Rillet

Invoice Butler + Rillet combine real-time accounting with end-to-end accounts receivable execution — closing the loop from invoice creation to cash in the bank.

Rillet is a modern accounting platform built for today's finance teams, replacing legacy ERPs with clear reports, real-time numbers, and a system designed for modern SaaS. But even the best ERP needs someone to follow up after the invoice goes out — and that's where Invoice Butler comes in.

Rillet generates the invoices and serves as the real-time system of record for revenue and receivables. Invoice Butler takes over everything after the invoice is issued: handling supplier portals, chasing payments, replying to customers, and escalating when needed — pushing collections until the cash lands in your account. Payment status and outcomes then flow back into Rillet automatically, keeping the books accurate and cash visibility fully up to date.

What the integration unlocks

• Invoices are created and tracked in Rillet, the real-time system of record for revenue and receivables.
• Invoice Butler manages end-to-end collections — follow-ups, customer communication, portal uploads, and escalations.
• Payment status and outcomes sync back into Rillet automatically: no parallel ledgers, no manual status tracking, no reconciliation headaches.

System of record meets system of execution. If you're upgrading your ERP but still relying on manual collections, this closes the loop from ledger to cash.
