Ecommerce books look simple from the outside and become a mess at scale. Settlement deposits net out fees, refunds, and chargebacks. Inventory has to move through cost of goods sold on accrual. Sales tax nexus is triggered by both physical inventory locations (FBA warehouses) and economic thresholds (sales volume per state). A CPA who has worked with sellers will use a tool like A2X or Link My Books to clean platform data into your general ledger, advise on which states need registration, and keep your reported income reconciled to what payment processors actually deposited.
