SupplySpy
SupplySpy analyzes supplier wholesale price lists in bulk and calculates product profitability for Amazon sellers.
What SupplySpy is
SupplySpy analyzes supplier wholesale price lists in bulk and calculates product profitability for Amazon sellers. Users upload .xlsx or .csv files containing at least product name, price, and UPC, then connect an Amazon seller account using a seller ID and MWS authorization token. Calculations include Amazon fees, ROI, profit margin, and sales rank, with costs such as shipping, multi-packs, referral fees, pick and pack, monthly storage, and inbound shipping taken into account. SupplySpy tracks ASIN data daily, including 7-day or 30-day average sales rank, price changes, and average prices. Amazon selling price, best sellers rank, and offer counts also refresh once a day. Extensive supplier lists may take up to 24 hours to upload. Product capacity is the number of products stored at one time, not a monthly upload allowance; deleting files can free capacity. The web-based service has a free plan with capacity for 50 products and unlimited suppliers. Growth (Annual) costs $20 a month billed annually, with 75,000 product capacity and unlimited suppliers.
