The short answer
Rillet runs your ledger and connects to tax partners for sales tax. Zamp calculates tax on your Rillet invoices, and our team owns SaaS taxability, nexus, registrations, filings and notices.
Tax is right on the invoice when it goes out, not fixed at month end. The compliance work moves off your team.
Zamp calculates rooftop-accurate tax on Rillet contracts and recurring invoices, itemized by jurisdiction. Invoices and credit memos post to Zamp as they're created, updated or deleted, so liability stays current through your close.

States don't agree on software. New York taxes prewritten software accessed remotely, Texas exempts 20% of a data processing charge, and many states don't tax SaaS at all. Zamp's team classifies what you sell and shows you the rule behind each call.
