Generate invoices in Campfire. Get paid by Invoice Butler.

The AI-native ERP for modern finance, plus autonomous collections: a real end-to-end finance stack, from ledger to cash in the bank.

Campfire

CEO Mihir Deo with John Glasgow, CEO of Campfire.

Campfire is the AI-native ERP changing how modern finance teams run their accounting: clean books, fast closes, and a modern general ledger built to scale. But generating the invoice is only half the job — someone still has to chase it.

That's where Invoice Butler comes in. Once invoices go out of Campfire, Invoice Butler takes over everything needed to actually collect: AR follow-ups, the replies and back-and-forth with customers, phone and text outreach, customer and supplier-portal submissions (Coupa, Ariba, and more), escalations, and cash collection. Collections activity then syncs back to Campfire and is journalized automatically — cash receipts, payment plans, and write-offs posted without manual entries.

What the integration unlocks

  • Ledger to revenue, fully connected. Campfire keeps the books clean and Invoice Butler gets you paid — no gap between generating an invoice and collecting on it.
  • Collections activity in your books, automatically. Payments received, payment plans, and write-offs sync to Campfire as journal entries, so your AR balance and aging always reflect reality.
  • No new headcount. Customers like FERMÀT and Coder already run the integration to automate everything from ledger to revenue — without adding an AR hire.

How it works

  1. Generate and send invoices in Campfire, your system of record for revenue and receivables.
  2. Invoice Butler takes over collections — follow-ups, customer replies, portal uploads, phone/text outreach, and escalations — until the cash lands.
  3. Payments, plans, and write-offs sync back into Campfire and journalize automatically, keeping your books and AR aging accurate.
