Paystand is a blockchain-enabled B2B payments and receivables automation platform that lets businesses send, receive, and reconcile payments with zero-fee bank-to-bank (ACH/EFT) transfers, card acceptance, and a Bitcoin-anchored "Assurety" certified audit trail. The Paystand Developer API (v3) exposes payments, refunds, disputes, payers, customer banks, accounts and balances, scheduled payments, transfers, withdrawals (including auto-withdrawal settings), a Checkout / Billing Portal embed surface, an Events resource, and the Assurety blockchain notarization APIs (assurors, chains, contracts, records, schemas, wallets). It integrates with major ERPs and e-commerce platforms (Magento, WooCommerce, BigCommerce) and is used to automate accounts receivable and payable for mid-market and enterprise finance teams.
