[Request an audit →](/book/) Retail · Beauty # Vendor promo funding wasn’t covering the margin given away. This marketing & margin audit surfaced **$41k in annual margin** in a Retail business, evidenced, senior reviewed, and delivered in 5 days. $1–3M annual revenue Beauty Focus: Vendor promo funding +$41k vendor funding recovered / yr −18pts uncovered promo cost 5 days to findings Promo discount covered by vendor funding Before audit 78% → After fix 96% ## The business A bricks and mortar beauty retailer ran frequent in store promotions cofunded by its brand partners, on the understanding that vendor support covered the cost of the discounts. Promotions drove strong footfall and sell through, and because the vendor funding arrived as agreed, whether it actually covered the full margin given away in each promotion was never reconciled. ## What triggered the audit Promotional periods drove volume but dented margin more than the vendor funding seemed to offset. The audit reconciled the margin actually surrendered in each cofunded promotion against the vendor support received, testing whether the funding genuinely covered the discount or merely softened it. ## What the audit found The vendor funding wasn’t covering the margin the promotions gave away. Deals were being negotiated and executed on the assumption that partner support offset the discount, but when the audit reconciled them line by line, the depth and volume of the promotions frequently exceeded the funding, so the retailer was absorbing the shortfall on every overrun promotion. Additional givebacks, staff time and markdown on promotional stock widened the gap further. Because the vendor money arrived as agreed and sell through looked strong, the uncovered portion was invisible; nobody checked the actual margin math against the actual funding. Reconciled properly, the retailer was quietly absorbing roughly $41k a year of promotional margin the vendor support never covered. ◉ How we produced this finding The vendor promo funding finding rests on a line by line reconciliation. MarginFix checked the retail ledger against actual delivery and payment, isolated exactly where value leaked, and had a named senior auditor trace and verify the figure to source before releasing it. Data sources: Contracts, invoices, billing records and delivery or fulfillment logs, reconciled against each other, so the exact gap behind vendor promo funding is traced to the specific line driving it rather than estimated from the top down. Key frameworks: Line by line ledger and contract reconciliation, unit economics and cost to serve analysis, framed by Forrester Total Economic Impact (TEI) for evidenced business value, cost and risk. Human validation gate: Every reconciled figure is checked against your own records and signed off by a named senior auditor before it ships. Nothing is reported without a human tracing it to source. Verified against POS / invoice ledger Promo & discount logs Landed cost sheet Promo calendar Finance P&L The vendor funding recovered / yr was measured like for like over a matched period, reconciled to invoiced margin in the P&L, and signed off by a named senior auditor before publication.

WORKING PAPER ████████ Beauty Representative Redacted Promo type Vendor covered discount Brand A promos 100% Brand B promos 92% Cofunded promos 78% vendor funding recovered / yr +$40,640 Recurring, recovered every year the fix holds, not a one off. Working paper: promo discount covered by vendor funding traced line by line and reconciled to invoiced margin in the P&L over a matched period. Line items representative and redacted; the recovered figure is the reconciled audit finding. ## What we changed ✓ Reconciled every cofunded promotion’s true margin given away against the vendor support actually received, exposing the uncovered shortfall on each deal. ✓ Renegotiated funding terms so partner support genuinely covers the depth and volume of each promotion, rather than only a portion of it. ✓ Set promotion guardrails capping discount depth to what the vendor funding actually supports, so overruns stop landing on the retailer. ✓ Made cofunded promotion margin a monitored metric, so uncovered givebacks can’t quietly accumulate across the promotional calendar. ## The result The published chart shows the share of the promotional discount covered by vendor funding rising from 78% to 96%, an 18 percentage point increase. The annual figure is recovered vendor funding, not a reduction in promotional spend. $41k a year recovered by making vendor promo funding actually cover the margin given away, an annual figure equal to 7× the $5,950 Audit + Sprint fee. For any retailer running cofunded promotions, the assumption is the leak: “the vendor pays for it” rarely gets reconciled against the real discount depth. If you’ve never checked promotional margin against the funding received, you may be absorbing a shortfall on every overrun deal. A fixed fee audit reconciles it in days, so partner promotions stop quietly costing you margin. From kickoff to signed off findings: 5 days. ![Portrait photograph of David Jackson](/assets/team/david-jackson.jpg) Reviewed & signed off by: David Jackson Senior Auditor · MarginFix · 10+ years of auditing experience ✓ Anonymized to protect the client · senior reviewed findings · Audit completed between 2024 and 2026, contracted through Cristian Bragau's practice before the MarginFix name existed · Published in the MarginFix library July 21, 2026 · Last reviewed October 24, 2026 ## What the client said RETAIL $41k a year found in 5 days Promo discount covered by vendor funding: **78% → 96%** “The vendor pays for it, we assumed.
