The economics

Modelled annual value · scales with retailer GMV

Same model, scaled across the enterprise tier. Weighted toward customer-acquisition efficiency over direct P&L margin. The structural floor of the CAC saving is independent of incrementality — full breakdown shared on partnership calls.

We'll run the model with your actual GMV, AOV, repeat rate and clearance volume — then walk you through it line-by-line. One spreadsheet your CFO can pressure-test.

The CAC framing

Stops looking like a marketplace fee. Starts looking like a customer-acquisition channel.

Translate Repurch's unit economics into the metric retail marketing teams actually live by. Effective CAC for a qualified store-credit customer sits materially below typical UK furniture-retail paid-channel acquisition spend — typically 4–7× cheaper, depending on retailer category and channel mix. The partnership stops sitting in your cost line and starts sitting in your CAC budget.

Effective CAC · UK furniture

Channel CAC (£)
Repurch · the channel 4–7× cheaper
Paid social £200–350
Paid search £280–450
Direct mail £300–500

The defensive floor

Even at half the modelled incrementality, the structural floor still scales with your GMV.

The acquisition-efficiency saving and the Clearance recovery (retailer keeps the large majority of net sale value) are structurally independent of cross-sell incrementality. At ~£100M revenue the floor stays around £3.5M; at ~£300M+ around £9.5M. Cross-sell is the upside lever, not the floor. Full incrementality sensitivity table and four-method measurement plan shared on request.

ESG & EPR positioning

An ESG narrative your sustainability team can finally measure. EPR-ready before the regulation lands.

UK Extended Producer Responsibility for furniture is on the regulatory horizon. Retailers with a credible take-back capability already in market won't be retrofitting under deadline — they'll already be running the operating model the rules will require.

Measurement methodology

We don't ask you to take incrementality on faith. We measure it. Quarterly.

The single assumption that drives the cross-sell line of the model is incrementality at 30%. The acquisition-efficiency saving and Clearance recovery are independent of it. We bake the measurement infrastructure in from partner onboarding — so you have audit-ready numbers to take to your Board by the time the partnership renewal comes around.

Randomised holdout

~10% of your customers form a control cohort that doesn't see Exchange during the measurement window. Comparing their 90-day new-furniture purchase rate to the 90% who do see it gives gold-standard causal incrementality. Configurable per partner; rotated each period so no customer is permanently excluded.

Pre/post difference-in-differences

Compare your customer cohorts before vs after Exchange launch, with industry retail-sales data as control. Confirms holdout findings; faster signal.

Survey at redemption

Two-question survey on credit-redemption confirmation: "Without the Exchange credit, when would you have bought?" Direct signal, cheap to run.

Time-to-next-purchase

Compare median days-to-next-new-furniture purchase for Exchange redeemers vs matched non-Exchange customers. Behaviour data, no survey bias.

Quarterly Board report

Triangulated incrementality estimate from all four methods. Delivered as a board-ready PDF + raw data export every quarter.

Audit-friendly

Independent-auditor methodology aligned with DEFRA + FCA-style frameworks. Numbers you can put in your annual report.

The argument, three ways

Same partnership. Three audiences. Three ways to tell the story.

For the Commercial team

The 30-second version

"This is not a marketplace partnership. It's a customer-acquisition engine. Each Exchange-credit customer brings you a £400+ qualified prospect with store credit ready to redeem. At industry-typical furniture-retail CACs, our service delivers customers at break-even on the credit gap with materially higher conversion intent than a cold-acquisition funnel. That conversion advantage compounds, on our modelled assumptions, to ~£5M annual value at £100M revenue — scaling to ~£14M at tier 1 anchor scale."

For the Sceptic / CFO

The defensive version

"Even at half the incrementality we project (15% instead of 30%), the partnership still delivers most of the modelled value. The acquisition-efficiency saving and the Clearance recovery — together the structural floor — are independent of incrementality, and scale proportionally with retailer GMV. We're not asking you to bet on cross-sell adoption. Cross-sell is the upside lever; the floor is structural."

For the CMO / Strategy lead

The strategic version

"Three things this partnership puts on your roadmap: a sustainability narrative with hard carbon numbers, customer credit lock-in that prevents migration to competitor brands, and a regulatory-ready take-back capability for when EPR rules drop. Early movers earn all three before resale becomes table stakes."
