Ecommerce brands that fulfil through a third-party logistics provider (3PL)
About Feeproof
Feeproof is a 3PL invoice auditing service with browser-based tools for ecommerce brands that use third-party fulfillment providers. Customers provide invoices (CSV or PDF), a 3PL contract, rate card or quote, and optionally a store order export; no 3PL or store login is required. Feeproof compares billed amounts with contract terms, invoice arithmetic and order totals to flag duplicate charges, rates above contract, unlisted or recurring fees, out-of-season surcharges, minimum-fee top-ups and unusual fee spikes. Each amount receives one of five statuses: Supported, Calculation mismatch, Conflicts with terms, Needs evidence or Not tested. The audit delivers a findings report, dispute letter with deadlines, promised-credit register and Excel export. Free browser tools include a three-invoice check and rate-card extraction. Paid monthly plans cover up to 3,000, 15,000 or 50,000 orders.
