Zoho Books is accounting software for running your business. You use it to send quotes and invoices, take online payments, track expenses and bills, reconcile your bank accounts, manage items and inventory, and report on how the business is doing.
Zoho Books doesn't provide tax compliance services itself. It doesn't monitor where you've crossed a state's economic nexus threshold, register you to collect tax, or file and remit your returns. For those, Zoho Books directs you to a separate service.
This is where Kintsugi helps. Kintsugi reads your Zoho Books transactions to track economic nexus across every US state and calculate what you owe, then registers, files, and remits returns for you. Monitoring is free, with transparent pricing and no per-order fees.
