Inventory variance is the silent margin killer. Shopify says 100 in stock. 3PL counts 87. Customer orders the 90th unit and gets a 'sorry, out of stock' email. Variance compounds invisibly until it costs revenue and trust.
DTC brands above $1M ARR with physical product. Critical above $5M.
Inventory accuracy is foundational. Every other ops decision assumes it. Marketing forecasts, reorder triggers, financial reports all rely on accurate counts. Variance corrupts each.
First business day of month. 3PL provides physical count, you compare to Shopify display.
Don't wait for monthly to catch high-velocity variance.
Define before you find variance, not during.
Damage at receiving, theft, system sync error, miscount. Pattern of one type points to process problem.
Physical count is truth. System lags physical, not other way around.
Same SKU showing variance 3 months in a row needs investigation.
Track variance dollars over time. Increasing trend points to operational issue.
Required for COGS calculation. Schedule with 3PL 60 days ahead.
Record your screen while running this procedure. ReccordSOP captures every step with screenshots, then alerts you when the actual process drifts from documentation.
Try ReccordSOP freeUnder 1 percent of unit count. Above 3 percent requires investigation. Above 5 percent points to systemic problem.
Monthly full, weekly cycle counts on top movers. Yearly full physical for finance/tax.
Depends on cause. Receiving damage usually 3PL responsibility. Customer-attributable usually brand. Document the SLA in your 3PL contract.
I built ReccordSOP after watching too many DTC ops teams lose months to undocumented workflows. These SOPs are battle-tested with Shopify operators running $1M to $50M brands.
