[Request an audit →](/book/) D2C · Food & beverage # A discount habit was training the best customers to wait. This marketing & margin audit surfaced **$68k in annual margin** in a DTC / Ecommerce business, evidenced, senior reviewed, and delivered in 6 days. $3–8M annual revenue Food & beverage Focus: Promo strategy +$68k margin recovered / yr +17pts full price sell through 6 days to findings Full price sell through Before audit 61% → After fix 78% ## The business A direct to consumer food and beverage brand had leaned on always on promo codes to keep sales ticking over, and they reliably did the job month after month. Over time, discounting had quietly become the default lever for hitting every target, applied across the whole customer base regardless of who was buying or whether they needed the nudge to purchase at all. ## What triggered the audit Full price sell through was drifting down even in genuinely strong months, the classic signature of a base that has learned to wait. The audit set out to separate demand that was truly incremental to the discount from demand the brand was simply giving margin away on, and to size how much the always on habit was really costing. ## What the audit found The analysis showed the always on codes were steadily eroding full price demand rather than expanding the market. The brand’s best, most frequent customers had been trained over time to hold out for a code they knew would always arrive, so a large share of discounted orders would have happened at full price anyway. The discount wasn’t buying incremental volume; it was subsidizing purchases the brand had already earned. Worse, the habit compounded, every month of always on promotion deepened the expectation and made full price feel like a penalty. Netted out against the small amount of genuinely incremental demand, the leak came to roughly $68k a year in margin handed to customers who needed no incentive. ◉ How we produced this finding MarginFix reached the promo strategy finding by doing what the ecommerce team hadn’t: rebuilding contribution margin cost by cost, so the real economics of every sale were finally visible. The figure is evidenced, tied to the client’s own data, and signed off by a named senior auditor. Data sources: Cost of goods, promo strategy inputs, fulfillment, fees, returns and discounts, reconciled per unit and per order, so the true contribution margin behind every single sale is visible rather than assumed. Key frameworks: A full contribution margin and cost to serve rebuild, full cost ROAS and margin based ROI analysis, framed by the Enterprise Marketing ROI Framework that treats spend as a capital allocation decision. Human validation gate: Every number is rebuilt on your own cost data and signed off by a named senior auditor before it ships. No figure leaves the building without a human standing behind it.

WORKING PAPER ████████ Food & beverage Representative Redacted Range Full price sell through New launches 81% Core range 76% Always on promo SKUs 61% margin recovered / yr +$67,690 Recurring, recovered every year the fix holds, not a one off. Working paper: full price sell through 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 ✓ Replaced the blanket always on codes with a tiered structure that rewards basket size and genuinely new customers, rather than everyone by default. ✓ Protected full price demand by removing the standing discount the loyal base had learned to expect, easing the change in gradually to avoid a volume shock. ✓ Introduced a deliberate promo calendar with clear on and off periods, so discounting becomes a chosen lever tied to objectives instead of an operating default. ✓ Added a full price share metric to reporting so the brand can see immediately if the discount habit starts creeping back. ## The result About $68k a year protected by breaking the always on discount habit, an annual figure equal to 11× the $5,950 Audit + Sprint fee, without denting volume. The uncomfortable part for any brand leader: full price sell through was eroding in plain sight, and the promo calendar looked like it was working the whole time. If your best customers have learned to wait for a code, you are already paying that tax every month, quietly, and volume masks it. It took a structured audit to separate incremental demand from margin simply given away, the same split almost no in house team runs.
