Anoowa Inc. has released its billFLO seller application programming interface for electronic invoicing for accounting system vendors, allowing invoices to automatically be imported into accounting systems.

Vendors can give their users the ability to send billFLO invoices directly from their accounting software. BillFLO provides machine-readable invoices that can be imported into common accounting systems, eliminating expenses and the potential for data entry errors.

“Demand from accounting system vendors for billFLO invoicing for their customers has been high,” said Anoowa CEO Ian Sweeney in a statement. “The ability to send a billFLO invoice is available to more than 75 percent all accounting system users today, and now with the API our goal is to make billFLO invoicing available to 100 percent of businesses.”

billFLO already integrates with many invoicing and accounting systems, including Harvest, FreshBooks, Less Accounting, QuickBooks and Blinksale, as well as proprietary systems of large enterprises.
