Stop guessing your Amazon profits. Start knowing them.
Fred Lundin CPA offers Amazon Data Enrichment Services specifically for third-party sellers who need financial clarity in a complex marketplace. Selling on Amazon involves more than just a title and a photo; it requires precise backend data to calculate fees, taxes, and profitability correctly. Many sellers operate with incomplete "flat files," leading to incorrect FBA fee calculations, missed sales tax collections, and "profit" numbers that don't match the bank account.
We audit and enrich your Amazon inventory data to ensure your financial foundation is solid. We populate critical fields such as Cost of Goods Sold (COGS) for accurate margin reporting, Product Tax Codes (PTC) for automated tax compliance, and precise package dimensions to prevent FBA overcharges. By treating your Amazon catalog as a financial database rather than just a marketing tool, we help you stop bleeding hidden fees and start making data-driven decisions about which ASINs to scale and which to cut.
