# Financial due diligence on an FMCG supplier or acquisition target
Three weeks before closing, a private equity buyer discovered that its target, a mid-sized snack food company, had shipped 40% more inventory into distributors in the final quarter than any prior year, with no matching rise in consumer takeaway. The deal price dropped by eight figures. This is the single most common trap in FMCG (fast-moving consumer goods) financial due diligence: revenue that looks real but is actually inventory parked one step down the supply chain.
This lesson walks through the checklist a due-diligence team runs on an FMCG supplier or acquisition target, and the regulatory backdrop that shapes it.
FMCG businesses sell high-volume, low-margin, repeat-purchase goods (think snacks, beverages, personal care) through complex retail and distributor networks. Two structural features make financial diligence distinctive:
A buyer isn't just checking if the numbers are accurate. They're checking if the numbers reflect what consumers actually bought.
Channel stuffing is shipping more product to distributors or retailers than they can sell, to inflate reported revenue in a given period. It's legal-adjacent until it becomes deceptive, at which point it can trigger securities fraud claims under the US Securities Exchange Act of 1934, enforced by the SEC (Securities and Exchange Commission).
The core diligence check: compare sell-in (shipments from manufacturer to distributor) against sell-out (actual retail scan data, i.e., what consumers bought at checkout). Retailers and syndicated data providers like NielsenIQ or Circana track sell-out; a widening gap between sell-in and sell-out is the classic red flag.
Worked example:
If distributor inventory days (inventory held ÷ average daily sell-out) jumps from 30 days to 55 days, that's a warning sign the company pulled forward future sales into the current quarter to hit a target, common right before a sale process or earnings deadline.
Other revenue red flags:
Trade spend covers slotting fees (payments to get shelf space), volume rebates, co-op advertising funds, and promotional discounts. It is typically the second-largest cost line after cost of goods sold, yet it is often the least controlled.
Two diligence issues recur:
1. Accrual accuracy: companies estimate trade spend liabilities before actual retailer claims arrive, sometimes months later. Under US GAAP (Generally Accepted Accounting Principles) and IFRS (International Financial Reporting Standards, used across the EU and UK), these are variable consideration estimates that reduce revenue (ASC 606 / IFRS 15 revenue recognition rules). Underestimating the accrual inflates reported revenue and margin, and the true liability surfaces only after closing.
2. Unreconciled deductions: large retailers deduct trade spend directly from payments owed, and if the company's books don't reconcile these deductions promptly, real liabilities hide in "disputed deductions" accounts for years.
Diligence check: request the trade spend accrual roll-forward (opening balance, amount accrued, amount paid or claimed, closing balance) for the last 8 quarters, and compare accrual as a percentage of gross revenue over time. A ratio that's unusually stable when promotional intensity is rising elsewhere in the category is worth questioning.
Many FMCG companies, especially mid-sized ones, don't own all their factories. They use co-manufacturers (also called co-packers), third parties that produce goods under contract. This creates specific financial and legal exposure:

Beyond revenue and trade spend, two more checks close out the core financial picture:
A simple margin bridge check:
Prior year gross margin: 38.0%
Price/mix impact: +1.2 pts
Input cost (commodity) impact: -2.5 pts
Volume/efficiency impact: +0.8 pts
Current year gross margin: 37.5%Even though the headline margin barely moved, this shows input cost pressure was masked by price increases, useful signal if commodity costs are expected to stay elevated post-acquisition.
