Connect Rillet once, and Kintsugi handles the rest: syncing your customers, invoices, credit memos, and products, calculating your tax obligations, and filing returns automatically. Your books stay accurate, and you stay audit-ready, without the manual work.

How it Works

Kintsugi connects directly to Rillet and automatically syncs your customers, invoices, credit memos, and products. This sets up Kintsugi to calculate your sales tax across every US state, plus VAT and GST in 100+ countries as you sell internationally.

Kintsugi calculates tax the moment invoices flow out of Rillet, so your general ledger and your tax obligations never drift apart. With Kintsugi as your indirect tax system of record, you're ready to automate registration, filing, and remittance everywhere you sell, and you've got the reporting to keep you audit-ready.

Rillet was built as a modern, AI-native alternative to legacy ERPs like NetSuite, with a faster general ledger and automated revenue workflows. Kintsugi was built the same way for tax. Together, they close the loop between what you book and what you owe, in real time, without a CSV export in sight.
