Inventory and cash flow benchmarks for ecommerce

Inventory turnover, days of inventory on hand by category, the cash conversion cycle, and how much revenue you should have tied up in stock. Inventory growth eats the cash before the revenue arrives, so these are the numbers that keep a profitable brand solvent.

MetricBenchmarkNotes
Inventory turnover4-6x a year for most; 6-8x for replenishment-heavy brandsAnnual COGS divided by average inventory value. Below 4x means too much stock; above 8x you may be understocking.
Days inventory on hand by categorySubscription consumables 30-60, food and bev 60-100, beauty 90-140, apparel 110-180, hard goods 120-200Wildly category-dependent. The slower verticals imply turnover below the 4-6x target, and those are category norms, not aspirations.
Days inventory outstanding60-120 days for most DTC brandsThe largest part of the cash cycle. Shopify and Stripe settle in 1-3 days, so inventory and supplier terms decide the rest.
Cash conversion cycleUnder 60 daysCCC = days inventory outstanding + days sales outstanding - days payable outstanding. The true cash exposure window is often 3-6 months, because the formula only starts once stock reaches your warehouse.
Inventory as a share of revenueMany brands sit at 20-30%; Quad Lock kept it under 15%Pipeline, on-hand and safety stock combined. Quad Lock tied up just 8-13% of revenue with very few stock-outs, but a low-SKU durable brand can run leaner than most, so plan off your own structural ratio.
In-stock rate95%+ on A-items; about 90% across the catalogueC-items can run leaner, and an 80-85% in-stock target is fine for them.
Supplier termsNet 30+ by your fifth orderMove from 30/70 deposits to graduated terms, such as 30% deposit, 30% on shipment and 40% Net 30.
Cash runway90+ daysKeep any single purchase order under 30% of available cash, and run a 13-week rolling cash forecast every week.
Inventory financing costUnder 15% annualised; inventory financing runs 8-20%Revenue-based financing runs 20-40% effective annualised, so match the capital to the job: supplier terms and financing for repeatable cycles, equity only for genuine bets.
Supplier lead timesIf the supplier says 30 days, plan for 60Reality usually runs 30-50 days. Ignoring lead-time variability is one of the most common inventory mistakes.

How to use these benchmarks

These ranges are directional, not guarantees. They are drawn from The DTC Playbook and Rob Ward's operating experience taking Quad Lock from $0 to a $500M exit, cross-checked against widely cited DTC data. The point is not the exact number - it is whether you sit above or below it, and what to do about the gap. Judge yourself against your own category and trend as well.
