BILL & Precoro API Integration: Close the Gap Between Purchasing and Payments

When a business is in its early stages, fragmented P2P processes don’t feel like a big deal. A quick Slack approval, a spreadsheet to track a few orders, and payments handled as they come—it works. Procurement and payments live in separate tools, and for a while, that’s manageable.

But as you grow, that simplicity quietly breaks down. Invoices arrive without a clear PO or approval history, forcing finance to double-check decisions across tools, repeat the same validations, and rely on manual confirmations. To keep work moving, employees start purchasing without POs. The result is familiar: budgets slip out of control, payments get delayed, and supplier relationships suffer. Scaling becomes messy and expensive.

The BILL and Precoro API integration connects procurement and payments into a single procure-to-pay workflow, eliminating manual handoffs and disconnected financial processes. Precoro manages the full procurement lifecycle, while BILL automates invoice payments. A robust two-way sync keeps supplier and transaction data perfectly aligned, so each stakeholder can clearly see what’s validated, paid, or still open. With all purchasing and payment information centralized, you get the control and confidence to scale without surprises.

“Fast growth shouldn't mean messy spending. I’ve seen too many businesses struggle because their buying and paying systems don't talk to each other. Our integration with BILL unifies the workflows, so you finally have a single view of your spend. Your teams stay fast, and your finances stay centralized and organized. It’s about growing your business without ever losing control of the reins.”
— Andrew Zhyvolovych, CEO at Precoro

Who will benefit most from the Precoro & BILL integration?

The integration is a game-changer for mid-market organizations that:

• Handle high transaction volumes where manual entry often leads to errors, delays, and rework.
• Operate across multiple entities, and need a centralized view of spend.
• Require tighter budget control, so finance can see committed spend before invoices reach BILL.
• Struggle with maverick spend, and want a structured purchasing process that teams will actually follow, without slowing down day-to-day operations.

If your finance or AP team spends hours reconciling invoices with purchase orders, or if you’ve ever paid a bill only to realize it wasn’t properly approved, this integration is for you.

How does the BILL & Precoro integration work?

The integration connects invoice processing in Precoro with payment execution in BILL through an automated, two-way sync. Approved invoices now flow seamlessly into BILL, and payment statuses appear in Precoro with a single click. You no longer need to retype records or worry about data inconsistencies again.

Here’s how the process works in practice:

1. When an invoice arrives, Precoro’s AI automatically extracts the data, matches it to the correct purchase order, and create a structured document.
2. The invoice then moves through your predefined approval workflows, where reviewers validate details before clearing it for payment.
3. Once approved, the invoice flows directly into BILL with all data pre-filled. Supplier records stay aligned across both systems as well.
4. AP processes the payment in BILL. The payment status then syncs back to Precoro, so all stakeholders see what’s been paid and what’s still open.
