The gap between Shopify's 'Total Sales' report and the amount actually deposited in your bank account, caused by processing fees, refunds, and adjustments netted out of the payout.
Total Sales is a top-line figure — it doesn't reflect what Shopify actually pays out. Between the sale and the deposit, Shopify's processing fee comes out, any refunds and disputes come out, and adjustments get netted in. Without breaking those out individually, the difference between 'what we sold' and 'what hit the bank' looks like one unexplained number every month.
ClairFlo buckets each payout's real transaction types — charge, refund, adjustment, dispute, reserve, fee — and posts each to its correct account automatically, so what's left flagged for review is a genuine discrepancy, not Shopify's normal fee structure. See Shopify features for the full breakdown mechanism.
