A managed sales tax service. Not a tool.
Most sales tax products hand you software and a to-do list. Zamp hands you a team. We register, file, remit, and answer the state, and we own the outcome.
Trusted by partners worldwide.
What managed actually means.
Zamp owns the outcome.
If a Zamp-managed calculation or filing results in penalties or interest, Zamp covers the cost. That's the Zamp Commitment, and it's on every subscription.
Nothing to learn.
You shouldn't have to understand sales tax to get it right. You review and approve. We prepare, file, and follow up. Your team never opens a state portal.
One price. Everything in it.
Registrations, filings, notices, and white-glove support are included. No per-transaction fees, no surprise invoices when you add a state.
Every part of sales tax, handled.
Nexus and registrations.
We watch your sales against every state's threshold and alert you at 80%. When you cross one, our team files the registration and adds the state to your calendar. You don't touch a portal.
Filings and remittance.
A specialist reconciles your data, prepares each return, and files it on the state's schedule. Payment goes out on time, and the confirmation lands in your account before you think to ask.
Notices and audits.
Every notice is received, reviewed, and answered by our team, inside the state's deadline. If one turns into an audit, we prepare the documentation and represent your interests with the state.
A team that answers the phone.
You get a dedicated point of contact who knows your business, backed by tax specialists and former state auditors. Not a rotating ticket queue, and not a chatbot standing in for one.
