Instant Accounts Receivables

Developers creating a product that would benefit from a built-in Accounts Receivable system can integrate directly with Bill & Pay to manage customers, create and send invoices, and receive payments through a branded customer portal. Integration can be as simple as provisioning new Bill & Pay accounts for your customers and embedding that account into your product.

Custom Synchronization

Use our API to integrate your vertical-market accounting system with Bill & Pay so that you can quickly start offering your customers an invoice delivery and payment acceptance solution. Our API provides everything needed to synchronize your customers, payments, and invoices to Bill & Pay and post payments made online back to your system.

Bill & Pay is the complete

invoicing and payment solution that has the best integration with QuickBooks and Xero. Accept ACH and Credit Card payments with any merchant account.
