Sequence + Rillet: The modern finance stack is here

The AI-native finance stack is forming, and next-gen ERPs like Rillet are at the center of it. Companies with established systems, such as NetSuite and Stripe Billing, are choosing to build their finance operations on Sequence for quote-to-cash and Rillet as their AI-native general ledger. With our new native integration, these systems now work together seamlessly. This matters because Sequence handles what legacy billing systems can't: multi-year ramped pricing, backdated contracts, percentage-based pricing, flexible usage minimums, mid-contract co-terms, and every other contract variation sales teams actually close. When you pair that flexibility with Rillet's AI-native ERP, finance teams finally get both: the ability to bill any contract accurately and the intelligence to close books in hours instead of weeks.

Finance teams shouldn't patch together their own stack

Until now, finance teams had to select from a new suite of modern tools which mostly existed in isolation. With the new Rillet integration, fast-growing B2B companies can reliably scale both their revenue workflows and GL.

What changes with the Sequence + Rillet integration

The new integration syncs your entire billing workflow into Rillet automatically:

Invoices flow automatically. When you finalize an invoice in Sequence, it syncs to Rillet with all invoice details, line items and service periods so you can close month-end confidently.

Product mapping stays clean. Map Sequence products to Rillet products once. Every invoice after that references the correct product IDs and GL account codes. Set a default product as a fallback to prevent sync failures while you're still mapping your catalog.

Payment status stays in sync. Mark an invoice paid in Rillet, Sequence reflects it. Both systems maintain consistent AR and payment states without manual reconciliation.

Customer records connect bidirectionally. Link Sequence customers to Rillet customers through the Sequence dashboard. Once linked, all billing data automatically references the correct Rillet customer record for proper GL posting.

Credit memos adjust revenue properly. When you issue a credit note in Sequence, it syncs to Rillet as a credit memo with service periods intact.

Why this matters

Finance teams migrating off NetSuite and Intacct want modern tools that work together, not disconnected systems that require manual data exports. This integration delivers that: Sequence handles CPQ, billing for complex contracts and real-time usage metering, Rillet handles multi-entity accounting and a streamlined month-end close. Now, Sequence and Rillet provide a seamless integration.

Extend Rillet with Sequence’s quote-to-cash platform

Sequence handles CPQ, contract quoting, complex billing scenarios like ramped pricing and usage-based charges, and mid-contract changes, all syncing directly into Rillet.
