What SupplySpy is
SupplySpy helps Amazon wholesale sellers assess supplier product lists and estimate product profitability. Upload a supplier file in .xlsx or .csv format with at least name, price, and UPC columns; the service calculates Amazon fees, ROI, profit margin, and sales rank. Its calculations can include shipping, multi-packs, referral fees, pick and pack costs, monthly storage, and inbound shipping. To connect an Amazon seller account, setup asks for a seller ID and MWS authorization token. SupplySpy tracks ASIN data daily, with 7-day or 30-day average sales rank, price changes, and average prices. Amazon selling price, best sellers rank, and offer counts are updated once a day. Extensive supplier lists may take up to 24 hours to upload. Capacity is based on the total number of products stored at one time, rather than a monthly upload allowance; deleting files can make room. The free plan costs nothing, billed annually, with capacity for 50 products and unlimited suppliers. Growth costs $20 a month billed annually or $29 a month billed monthly, with 75,000 product capacity and unlimited suppliers.
