BILL
Paying bills the old way means paper invoices, a stamp from everyone who has to approve, and a checkbook that needs two signatures. BILL deletes all of it. Invoices land in an inbox, get coded, route for approval on someone's phone, and pay themselves, while Divvy cards handle company spend with limits built in. Its newer AI agents even chase W-9s and reconcile the receipts nobody wants to touch. BILL builds the tools, Hiline implements and runs them, so a small business gets enterprise-grade AP without the enterprise headcount.
AP Done Right

Longest Partner
BILL is one of Hiline's oldest and closest partners in the finance tech world, going back 7+ years. BILL runs the number-one AP solution in the country, and it sits underneath most of Hiline's clients.

Set Up to Run
Hiline builds the whole AP workflow on BILL: coding, approval routing, spend controls, receipt capture, and grant vouchering, all tied straight into the books. BILL is the engine; Hiline owns the layer above it that makes it actually work for a client.

Agents on the Grunt Work
BILL's AI agents take the jobs nobody wants. The W-9 agent chases and validates vendor tax forms on its own (cutting roughly 80% of the manual steps), and the expense agent auto-codes Divvy receipts. Hiline's team helped beta-test the W-9 agent before it shipped and now manages it for its customers.
"
You can have the greatest tools in the world, but if you don't know how to use them, if they're not the right tool for the job, then nothing else matters. Having the right tool is super important. Knowing how to use it, having the advice, being able to show them how to use it – that's how BILL and a firm like Hiline work together.
