Marketplace · B2B wholesale
Buyer subsidies outran the repeat GMV they were meant to unlock.
This marketing & margin audit surfaced $66k in recurring annual margin in a Marketplace business, evidenced, senior reviewed, and delivered in 7 days.
The business
A B2B wholesale marketplace acquired new buyers with onboarding subsidies and first order incentives, justified on the lifetime GMV each buyer was expected to generate. Buyer growth was strong, and the lifetime value assumption underpinning the subsidies had been set early and applied broadly, without ever being tested against how those buyers actually behaved over time.
What triggered the audit
Buyer acquisition looked efficient against projected lifetime GMV, but cash didn’t reflect it, hinting the LTV assumption was too generous. The audit tested the actual repeat GMV behavior of subsidized buyers against the lifetime value the subsidies had been justified on, cohort by cohort.
What the audit found
The subsidies were being justified on a lifetime GMV that most buyers never delivered. The early LTV assumption, set when the marketplace was young and applied uniformly ever since, assumed subsidized buyers would return and reorder at a rate the actual cohort data flatly contradicted. A large share placed one subsidized first order and rarely came back, so the incentive was effectively a one off cost with no lifetime value behind it, while the healthy projected payback existed only on the spreadsheet. Because buyer counts kept growing and the assumption went unchallenged, the marketplace continued scaling acquisition on economics that simply weren’t real. Measured against genuine repeat GMV, the subsidized segment paid back far worse than assumed, and realigning it improved buyer payback by 26%.
What we changed
Reset the lifetime GMV assumption to actual measured repeat behavior, cohort by cohort, rather than an early projection that had been applied across the whole base.
Capped subsidies on the buyer segments that don’t reorder, and concentrated them on the segments with proven, repeatable GMV behind them.
Switched acquisition reporting to genuine repeat GMV payback, so no cohort can be scaled on projected lifetime value alone.
Set guardrails tying subsidy levels to demonstrated buyer retention rather than the optimistic early forecasts that no longer held.
The result
The published chart shows payback on subsidized buyers moving from 0.8× to 1.3×. The separately reported 26% buyer payback improvement is not presented as the percentage change between those two endpoints. Buyer payback improved 26% by subsidizing only the buyers who actually come back. For any B2B marketplace, the trap is the early LTV assumption: applied broadly and never tested, it lets acquisition scale on economics that exist only in the model. If your subsidies rest on projected lifetime GMV rather than measured repeat behavior, you may be buying one off orders at a lifetime price. It takes cohort level repeat analysis to see it. A fixed fee audit does that in days, before you fund more of the gap.
From kickoff to signed off findings: 7 days, inside our fixed 5–7 day window.
This +26% buyer payback gain is ≈$66k/yr at the client’s revenue scale.
