The verdict, the seven findings behind it, and the recovery they point to.
How this diagnostic was built, and what it is, and is not, for.
This diagnostic is built entirely from information supplied by the recipient, or reconstructed from the recipient's own systems, and from assumptions agreed with the recipient. The figures have not been independently audited. Their accuracy depends on the completeness and accuracy of the inputs provided.
The report is a commercial decision-support tool. It is intended to inform capital-allocation and marketing-investment decisions, not to serve as a financial audit, statutory account or formal valuation. Its directional conclusions, rather than its precise decimal figures, are what it is designed to support.
All figures in this document are illustrative, internally reconciled to demonstrate the method, and anonymised. They represent no actual business or client. A live diagnostic is validated with the recipient's finance team so that its result is one the board will accept as documented fact rather than estimate.
The verdict, the headline numbers, and what they mean.
Your acquisition engine returns roughly 53 pence for every pound it spends winning a customer, a shortfall of about £835,000 a year at the current rate of acquisition.
| Measure | Result | Against benchmark |
|---|---|---|
| CLV : CAC, fully loaded | 0.53 : 1 | Below break-even (1:1) and healthy (3:1) |
| Capital Burn Velocity | −£69.6k / mo | ≈ £835k a year at run-rate |
| CAC payback, loaded | ≈ 25 mo | Beyond the ≈ 24-month average tenure |
Fully-loaded acquisition cost measured against margin-based, discounted lifetime value. Detail in Sections 03 to 05.
Your acquisition engine is not currently repaying what it costs to run. Measured on fully-loaded acquisition cost against margin-based, discounted lifetime value, your blended CLV:CAC ratio is 0.53:1. For every pound you invest in winning a customer, roughly 53 pence returns across that customer's life with you. At your current rate of about 3.3 new customers a month, that shortfall compounds to approximately £69,600 a month, or £835,000 a year at run-rate.
You have been working to a ratio close to 3.8:1 and a payback of about nine months. On the inputs that view used, it was a fair reading. The distance between 3.8:1 and 0.53:1 does not reflect a deterioration in your business. It reflects what those inputs included. Three measurement conventions, each ordinary and each defensible on its own terms, moved your reported position in the same direction.
Cost was drawn narrowly. Your reported CAC of £16,000 counted the spend that leaves your business as marketing: media, events and agency fees. It did not carry the loaded salaries, the business development effort, or the technology that also go into winning a customer. Value was read on revenue. Lifetime value was taken as contract value across tenure, before gross margin, before the cost of serving the customer, and without discounting future income to present value. Pipeline was credited on multi-touch. Every channel a buyer touched claimed a share of the same opportunity, so channel contribution summed to more pipeline than you originated.
Corrected on all three, the position turns over. This is the ordinary shape of the error rather than an unusual one, and it is precisely why it went unseen: no single input was wrong on its own terms. The three simply compounded, and all three pointed the same way.
At £44,500 to win a customer worth £23,625, each new customer opens a gap of £20,875 before it has repaid what it cost to acquire. Multiplied by your rate of acquisition, that gap becomes a velocity rather than a number: capital leaves at roughly £69,600 a month. Your loaded payback, at about 25 months, now sits beyond your average tenure of about 24 months, which means the typical customer leaves before repaying the cost of winning them.
The shortfall is not spread evenly. Your SMB book runs at 0.23:1 and accounts for 49% of the total while producing 55% of your new logos. No segment has yet reached break-even, so there is no healthy segment subsidising the rest. Cut a different way, by how customers are won rather than by size, the same concentration appears: your two-tier distribution route returns 0.14:1 against 0.69:1 direct, because roughly a third of its margin is conceded to the channel and a fully-loaded partner programme sits on top of the cost to win. That matters for the recovery: this is a question of where you acquire and how, not of whether marketing should spend less.
Sections 03 to 06 set out each finding, what it means for you, and what it costs. The recovery is set out in Section 07, where every recommendation is referenced back to the finding it answers.

You are not running one acquisition model. You are running three, none of them yet at break-even, and the most fuel is going to the weakest of them.
Six outputs at a glance, and the figures the analysis is built on.

Each output answers a capital-allocation question. Detail in the sections that follow.
The diagnostic is only as good as what goes into it. These are the figures you provided, or that were reconstructed from your systems, with retention costs separated from acquisition throughout.
| Input | Value | Source |
|---|---|---|
| New customers won (12 months) | 40 | CRM, closed-won |
| New customers per month | ≈ 3.3 | Derived |
| Average annual contract value | £30,000 | Finance |
| Gross margin | 70% | Finance |
| Average retained tenure | 2.0 years | Cohort, CRM |
| Reported CAC (media + programme) | £16,000 | Marketing |
| Cost-to-serve | 25% of margin | Finance, ops |
| Discount rate | 10% | Finance policy |
Acquisition and retention costs are held separate. Mixing them is the most common single cause of a CAC figure that answers neither question.
The true cost to win, and the true value won.
Your reported CAC of £16,000 captured paid media, events and agency fees. Adding the loaded sales and marketing headcount (£18,900), the business development and SDR effort (£5,600), and the technology that supports acquisition (£4,000) brings the fully-loaded cost of winning one new customer to £44,500. Retention costs are held out throughout, so the figure answers the acquisition question alone.
The £28,500 difference is not new spending. It is spending you already make, attributed to the activity it belongs to. The convention that produced the reported figure, counting only the money that leaves your business as marketing, is common and is not a reporting failure. It simply answers a narrower question than the one capital allocation asks: not what did marketing spend, but what did it cost to win a customer.
Your reported figure represented 36% of the loaded cost, so decisions priced against it were priced against roughly a third of the real number. Every acquisition judgement you have made on it, channel budgets, segment focus, sales capacity, carries the same distortion, and will continue to until the loaded figure becomes the planning figure.
| Cost component | Added | Running total |
|---|---|---|
| Reported CAC — media, events, agency | £16,000 | £16,000 |
| Sales & marketing, loaded headcount | + £18,900 | £34,900 |
| Business development & SDR effort | + £5,600 | £40,500 |
| Acquisition technology — CRM, data | + £4,000 | £44,500 |
| Fully-loaded New Customer CAC | 2.8× | £44,500 |
Each held-out cost added in turn. Retention is excluded throughout, so the number answers the acquisition question alone. A reported CAC typically represents 25 to 40 percent of the loaded figure; yours is 36%. The £28,500 difference is spend you already make on winning customers, attributed elsewhere.
Lifetime value was being read as contract value across tenure, before margin and without discounting. Read on gross margin, net of the cost to serve, and discounted to present value, the lifetime value of one of your customers is £23,625, against the £60,000 in view.
Revenue is not what a customer returns to you. Margin is, and it arrives over time rather than at once. The build below applies each correction in turn: gross margin at 70% takes your £30,000 contract to £21,000 a year; your average retained tenure of 2.0 years gives £42,000 of gross margin across the customer's life; the 25% cost to serve removes £10,500; and discounting future margin at 10% removes a further £7,875. None of these are pessimistic assumptions. They are the conventions your finance team would apply to any other investment of the same size.
The revenue-based figure overstated what each customer returns by roughly 2.5 times. Read together with Finding 01, this is the second of the three movements that carried your reported ratio to 3.8:1: one lightened the cost, one inflated the return, and they compounded.
| Annual contract value at 70% gross margin | £21,000 / yr |
| × Average retained tenure (2.0 years) | £42,000 |
| − Cost-to-serve (25%) | − £10,500 |
| − Discount to present value (10%) | − £7,875 |
| Net CLV, discounted, after cost-to-serve | £23,625 |
Your revenue-based, undiscounted CLV overstated the return by roughly 2.5 times. Read with Finding 01, both corrections move the ratio in the same direction.
The third movement behind your reported position.
Under multi-touch attribution, every channel a buyer touches claims a share of the same opportunity, so your channel totals sum to more pipeline than you originated. Re-cut to first-touch, the channel that genuinely started each opportunity, your claimed contribution of £6.0m reconciles to £2.1m, an over-claim of 2.9 times.
This is not a reporting failure by your marketing team, and the channels are not competing for credit dishonestly. Multi-touch is the default in most CRM and automation platforms, and it is genuinely useful for understanding influence: it answers "what did the buyer encounter?". It cannot answer "what created this opportunity?", because it deliberately shares one opportunity across many claimants. Used for capital allocation, that sharing double-counts, and the over-claim is largest in the channels that touch buyers late (outbound at 4.5 times, events at 3.8 times) rather than those that start them.
This is the third movement, alongside the cost and value corrections, and it compounds them. Cost was understated, value was overstated, and pipeline was over-credited, all at once and all in the same direction. It also means channel budgets have been set against contribution figures that cannot be reconciled to originated pipeline, so the money has been following influence rather than origination.
| Channel | Claimed | First-touch verified | Over-claim |
|---|---|---|---|
| Paid search | £2.4m | £0.9m | 2.7× |
| Events & field | £1.5m | £0.4m | 3.8× |
| Content & SEO | £1.2m | £0.6m | 2.0× |
| Outbound & SDR | £0.9m | £0.2m | 4.5× |
| Total | £6.0m | £2.1m | 2.9× |
Claimed pipeline contribution against first-touch verified. The gap is the double-counting that multi-touch attribution permits, and a large part of why marketing-reported ROI ran ahead of the financial reality. Channel mix shown is illustrative.
Three conventions, each reasonable on its own, moved in the same direction at the same time. That is why the position held together, and why it did not survive being measured.
The ratio tells you if. Burn Velocity tells you how fast.
At £44,500 to win a customer worth £23,625, you are £20,875 short on each new customer before that customer has repaid the cost of acquiring them. At your rate of roughly 3.3 new customers a month, that per-customer gap becomes a rate: approximately £69,600 a month, or £835,000 a year at run-rate.
A ratio tells you whether the engine repays. A velocity tells you how quickly the position moves while you decide what to do about it, which is the number a board needs. It is worth being precise about what it is not: this is not your total cash burn, and it is not your runway. It is the rate at which one activity, winning customers the way you currently win them, moves capital off the table. It is also the reason the position is easy to miss. Nothing fails visibly at 0.53:1; the engine simply runs, and the cost accrues.
Your loaded payback of about 25 months now sits beyond your average tenure of about 24 months. That is the sharper edge of this finding: on today's economics the typical customer leaves before repaying what it cost to win them, so the shortfall is not deferred revenue that arrives later. It does not arrive.
| Fully-loaded New Customer CAC | £44,500 |
| − Net CLV | − £23,625 |
| Economic gap, per customer | − £20,875 |
| × New customers per month (≈ 3.3) | − £69,600 / mo |
| Capital Burn Velocity, annualised | − £835,000 / yr |
The per-customer gap at your current pace of acquisition. It isolates the acquisition engine alone, and excludes retention and every other cost in the business.
Your measured CLV:CAC against the break-even and healthy benchmarks, the scale pivoting on the 1:1 line. Your reported position sat in the healthy band; your measured position sits below break-even.
Because each new customer currently costs more than it returns, additional volume adds to the shortfall rather than reducing it. On today's economics, every extra pound of acquisition spend and every extra customer won widens the gap.
This inverts the usual relationship between growth and efficiency, and it is the most counter-intuitive part of the position. Scale normally improves unit economics. Here it cannot, because the unit itself is loss-making: multiplying a negative does not change its sign. The common response, investing harder into growth to earn the way out, accelerates the loss rather than closing it, and it does so quietly, because volume rises at the same time.
Your growth plan and your recovery are, for the moment, in tension. Any target that increases new-customer volume before the unit economics reach 1:1 will increase the annual shortfall roughly in proportion. The sequence therefore matters more than the ambition: reach 1:1, then scale, and the same plan becomes accretive.
Growth is not the problem, and it is not the answer yet. On these economics it is a multiplier, and the number it is multiplying is negative.
Where the capital is going, by segment and by route, against the reference lines.
Your blended 0.53:1 is an average of three different economics, not a single position. Split out, your SMB book runs at 0.23:1 and carries £407,000 of the annual shortfall, 49% of the total, on 55% of your new logos. Mid-market runs at 0.57:1 (£325,000) and enterprise, your strongest, at 0.79:1 (£103,000). None has reached 1:1.
A blended ratio hides as much as it reveals, and here it hides the most important fact about your engine: there is no healthy segment subsidising the rest. In most businesses with a poor blended number, one segment is carrying the others, and the recovery is a reallocation towards it. That option is not open to you yet. Your strongest segment still returns 79 pence in the pound. Enterprise wins few customers and comes closest to repaying; SMB wins the most and is furthest from it, which is why the blended figure sits nearer the weak end than the strong one.
Your growth is concentrated in your least economic segment, so volume and shortfall are currently rising together. It also sets the order of the recovery: SMB is where roughly half the addressable capital sits, and it is the segment where the change is structural rather than incremental, because the cost of the sales-led motion is greater than anything that book can repay.
| Segment | New custs | Loaded CAC | Net CLV | CLV:CAC | Destroyed / yr |
|---|---|---|---|---|---|
| SMB / self-serve | 22 | £24,000 | £5,500 | 0.23 : 1 | − £407,000 |
| Mid-market | 13 | £58,000 | £33,000 | 0.57 : 1 | − £325,000 |
| Enterprise | 5 | £99,600 | £79,000 | 0.79 : 1 | − £103,000 |
| Blended | 40 | £44,500 | £23,625 | 0.53 : 1 | − £835,000 |
SMB wins the most customers and carries the largest share of the shortfall: 55% of new logos, 49% of the total. Enterprise wins fewest and comes closest to repaying, but still falls short of 1:1.
The same 40 customers, cut by how they were won rather than by size, divide into two routes. Direct sales win three in four of your new customers and return 0.69:1. The two-tier distribution route, the remaining quarter, returns 0.14:1. That is the weakest economic position in this report, below even SMB, and it is structural to the route rather than a matter of execution.
Two mechanisms drive it, and they pull on opposite sides of the ratio. The margin conceded to the channel, roughly a third of list once the distributor and reseller shares are stacked, is a permanent reduction in gross margin, so it lowers lifetime value on every deal the route wins. The programme that supports the channel, partner marketing, deal-registration incentives and the loaded cost of the partner-management team, is acquisition cost, so it raises the cost to win. A lower average contract value on the volume route compounds both. The route gives away a third of its margin to win customers worth half your direct average, and pays a fully-loaded programme to do it.
At 0.14:1 the two-tier route returns close to nothing on what it costs, and it is one of the reasons the blended 0.53:1 sits where it does. The route is not inherently uneconomic; distribution earns its place on reach into buyers a direct team cannot cover. But on the current give-away and programme cost it does not repay, and the diagnostic prices that plainly so the decision can rest on the number rather than on the relationship.
| Route | New custs | ACV | Loaded CAC | Net CLV | CLV:CAC |
|---|---|---|---|---|---|
| Direct | 30 | £60,000 | £42,000 | £29,000 | 0.69 : 1 |
| Distribution, two-tier | 10 | £30,000 | £52,000 | £7,500 | 0.14 : 1 |
| Blended | 40 | £52,500 | £44,500 | £23,625 | 0.53 : 1 |
The channel discount, the distributor and reseller shares stacked to roughly a third of list, is treated as a reduction in gross margin and lowers CLV. The channel programme and the loaded partner-management cost are treated as acquisition cost and raise CAC. Direct and two-tier are distinct customer populations, not the same customer counted twice.
| Reference | Benchmark | This business | Status |
|---|---|---|---|
| Break-even (capital preserved) | 1.0 : 1 | 0.53 : 1 | Below |
| Healthy B2B acquisition | 3.0 : 1 | 0.53 : 1 | Below |
| CAC payback (loaded) | < 12 mo | ≈ 25 mo | Beyond tenure |
| CAC payback (reported, media-only) | < 12 mo | ≈ 9 mo | Flattered |
On the reported, media-only basis the engine read as healthy: a 9-month payback and a ratio near 3.8:1. Both figures are internally consistent; they simply measure a narrower question.
Top actions ranked by impact, each referenced to the findings it answers.
Ranked by the capital each addresses at run-rate. Every recommendation is referenced to the findings it answers, so the report can be read in either direction.
The aim is not for you to spend less on marketing. It is to bring the engine to the point where it repays what it costs, and then to grow it. Each recommendation sets the direction, the capital it addresses, an owner and a horizon. The build itself, the specific programmes, targets and the order they are executed in, is the work of the Marketing & Capital Plan, which turns these directions into a costed, sequenced plan your team can run.
Your SMB book returns 23 pence for every pound spent winning it, and it is currently won through a sales-led motion that costs more than the segment can repay. The recommendation is not to abandon SMB. It is to change how it is acquired, so that the cost of winning comes within what the segment returns, and to stop funding it through the high-cost path in the meantime. This is first because it is the largest single pool of addressable capital and the change is structural rather than incremental: no amount of efficiency inside a sales-led motion will close a gap this wide.
The cost of winning SMB has to fall to within what the segment returns, which points away from the high-touch sales motion and toward a lower-cost acquisition model for that book. The routing of leads and the incentives behind them also currently push SMB into the most expensive path. Which model, at what cost target, and how the transition is sequenced without disrupting live pipeline is the work of the Marketing & Capital Plan.
Your tenure of 2.0 years and your 25% cost-to-serve are the two levers on the value side of the ratio. Moving mid-market and enterprise tenure toward 2.6 years, and trimming the cost to serve, lifts net CLV materially and pulls both segments toward break-even without winning a single additional customer. It is worth being clear why this ranks second rather than first: it is the cheaper half of the ratio to move, because you already have these customers, and it improves the return on every customer you win from here rather than only the next one.
The value side moves through longer tenure and a lower cost to serve, so the emphasis shifts toward retention, expansion and the quality of the customers acquired in the first place. There is a compounding effect available here, since better-retained customers also lower future acquisition cost. The specific programmes, the tenure and cost-to-serve targets, and the order they are built in are set in the Plan.
Most of your deals currently begin cold and are argued on price. That has a measurable cost, and it sits inside the loaded CAC in Finding 01: unfamiliar buyers take longer to close, absorb more sales time, and concede less on price, all of which are carried as acquisition cost. Building category salience with future buyers lowers the cost to win across all three segments. It is the one lever that moves both sides of the ratio at once, since a buyer who already knows you is cheaper to acquire and easier to retain at full price. It ranks third because it is the slowest to compound, not the least valuable.
A weak brand is paid for in hard acquisition cost, so the direction is to build familiarity with future buyers ahead of the point of sale, which lowers the cost to win across every segment. The balance between brand and activation, the positioning itself, and the measures that show it working are established in the Plan, drawing on the recognised B2B effectiveness evidence.
Three of the findings are measurement rather than performance: your cost was drawn narrowly (F1), your pipeline was credited 2.9 times over (F3), and neither was visible in a form that would show growth widening the gap (F5). The number that determines whether acquisition creates or destroys capital cannot be managed while nobody is required to produce it. This is the recommendation that protects the other four, because without it the position can drift back without anyone seeing it happen. It is also where marketing leads rather than waits: owning this number changes the budget conversation from defending activity to directing capital.
The fully-loaded, segment-level ratio needs to become a standing number rather than a one-off finding, which means giving it an owner, a data source and a place on the board pack, and reading attribution on a first-touch basis for allocation. The operating model that sustains this, and the reporting cadence around it, is defined in the Plan and handed to your team to run.
Your enterprise segment comes closest to repaying, at 0.79:1. Once SMB is contained (R1) and net CLV is lifted (R2), a measured shift of acquisition effort toward mid-market and enterprise is what carries the blended ratio through 1:1, and it does so more efficiently than spreading the same spend across all three. This comes last deliberately. Re-weighting toward enterprise before the value side moves would simply buy more of a segment that does not yet repay either, so the sequence protects you from solving the mix while the economics are still negative.
Once the value side and the SMB motion have moved, the mix of acquisition effort should tilt toward the segments that come closest to repaying, which favours fewer, better-fit customers over maximum logo count. The target weighting, the account definition and the sequencing against the other actions are set in the Plan, so the shift lands without starving the pipeline mid-transition.
Read together, this is a recovery, not a cost-cutting exercise. Two of these reallocate spend, two create value, and one fixes the measurement that kept the position out of view. None of them asks for a bigger budget. They ask for the budget you already have to be pointed at retained value rather than logo count.
This report tells you where the business stands. The Marketing & Capital Plan is the fixed-fee engagement that acts on it: scoped to these findings, built to reduce CAC, lift net CLV and slow the burn, with the diagnostic fee credited in full. It is reserved at the read-out, not sold from a page.
The interpretation, the assumptions, and the basis of preparation.
The report is the artefact. The read is the meaning. A specimen of how the findings are talked through, in plain terms, at the read-out.
The headline number will sting, so it is worth being clear about what it does and does not say. This is not your cash burn, and it is not a comment on your business as a whole. It is the rate at which one engine, the way you currently win customers, moves capital off the table. At 0.53:1 it is below the line where a customer pays back what it cost to win them.
The part I would sit with is the reported view. On the numbers you were looking at, a 9-month payback and something close to 3.8:1, you were right to feel the engine was healthy. There was nothing careless about it. The figure was understated because it left out the people and the time, and the value was overstated because it was read on revenue. Correct both and the picture turns over. That is the normal shape of the error, not an unusual one.
If I were deciding where to start, it would not be a cost-cutting exercise. It would be the SMB book, because that is where the money is going fastest, and the brand point, because that is the one lever that lowers the cost to win everywhere at once. Growth is not the enemy here. Growth on these economics is. Get the engine above 1:1 first, then it is worth pouring fuel on.
None of this needs to be acted on today. It needs to be seen clearly, by you and by whoever holds the capital. That is what this is for.
