CAC payback is longer than we can finance
Here is how to work out why.

The short answer

If CAC payback is longer than you can finance, stop scaling the channel. Rank by contribution payback, not by CAC alone, and only then spend. Go-to-Market & Commercial Strategy (t9) is the engagement. Creative tests do not repair a payback that the unit economics cannot close. Percision is not a media-buying desk.

CAC without payback is a vanity. A cheap click that takes twenty months to return contribution will bankrupt a company with twelve months of cash. A expensive click that returns in four months is a line of credit you should want more of. Blended CAC hides this completely, which is why “marketing is not working” and “we cannot finance growth” are often the same problem described by different functions.

The first cut is cohort contribution, not last-click CAC. If the paid cohort churns, payback never arrives. If the best customers already sit in the book, retention and wallet-share are cheaper than another top-of-funnel push — that is the neighbouring canonical on marketing spend. This page is specifically the finance constraint: payback versus runway.

Live catalog id t9 is Go-to-Market & Commercial Strategy (the inventory’s “GTM Strategy”). Pricing & Revenue Optimization (t7) is the second engine when the offer itself cannot support any reasonable CAC. EFF is the third when the issue is contribution, not channel.

SaaS language (NRR, ACV, land-and-expand) belongs in the copy where it is true. There is still no -in-saas industry grid: b2b-saas has no published run excerpt. Home-services paid lead gen has the same arithmetic with jobs, not seats.

How to tell this is actually your problem

These three together are the signature. One on its own usually points somewhere else.

✓ Payback in months is longer than cash runway in months
✓ Blended CAC looks acceptable and channel-level CAC does not
✓ The response so far has been more creative tests on the same channel

The move that usually makes it worse. Scaling spend to “make it up on volume” on a channel whose contribution payback already exceeds runway.

Who this is not for

Percision is the wrong tool if you already know the answer and only need execution capacity, or if the business is pre-revenue — then the constraint is evidence about the market, not analysis of your own figures. Percision is not a lawyer, tax advisor, auditor, licensed appraiser, clinical or regulatory filer, or an AI implementation shop. It does not do HR casework, creative-only brand work, or impersonate a named consulting firm. It is a strategy analysis engine — not a template library. Also wrong if you need facilitation, politics, or someone to sit with a lender or buyer. Those are human jobs.

Industry cuts

Industry pages at {problem}-in-{industry} ship only with an unedited run excerpt. This canonical has none yet, so there is no eleven-cell grid and no -in-saas door. Home-services operators (HVAC, plumbing, electrical, landscaping, cleaning) hit the same binds as other owner-operated trades: crews fully booked, contribution unknown by job type, and growth that still depends on the owner answering the phone. Percision can analyse that shape of business. There is no /strategy-for-home-services hub yet — industry pages ship only with a named profile and an unedited run excerpt, so this language lives on the operator pages rather than as a twelfth grid.

What the engine does with this question

It routes to Go-to-Market & Commercial Strategy (catalog id t9), one of 29 engagements. The output is a sequence with a stopping rule — which move first, what it funds next, and the observation that would say it is not working — rather than a list of things you could consider.

Questions people ask about this

Should we cut all paid until payback improves?

Cut the channels whose payback you cannot finance. Keep the ones that return inside runway. A blanket pause is how you also kill the one channel that was working.

Is LTV/CAC enough?

No. LTV that arrives in year three does not pay a bill in month nine. Payback in contribution months is the number that has to fit the cash.

Will a brand campaign fix this?

Not as a substitute for unit economics. Brand can lower CAC later. It does not change a contribution hole in the current offer.
