Sales tax nexus tracking, in real time.
Nexus thresholds differ by state and reset every year. Miss one and you're collecting without authority, or not collecting at all. Zamp watches all 50 states.
Trusted by partners worldwide.
Know before you cross the line.
Proactive, not reactive.
Most businesses learn about nexus from an auditor. Zamp clients hear about it from us, with time to register before the obligation starts.
No gap between nexus and registration.
Hit a threshold and registration starts. Nobody has to notice, nobody has to file a ticket.
State rules, kept current.
46 states have economic nexus laws, and they change. We maintain our rules engine continuously, so you're measured against today's rules, not last year's.
How economic nexus monitoring works.
Revenue and transactions, live.
Zamp pulls sales data from your e-commerce platform, ERP, or billing system and measures it against each state's current economic nexus rules. You see where you stand before a threshold, not after.
Physical nexus, too.
Employees, warehouses, and inventory create nexus as surely as sales do. Zamp tracks physical presence factors alongside economic activity, so a 3PL in a new state doesn't slip past.
One view, every state.
A state-by-state dashboard shows where you have nexus, where you're approaching a threshold, and where you're not yet obligated. No spreadsheet, no 46 browser tabs.
Alerts, then registration.
We flag an approaching threshold with enough lead time to act. When you cross it, Zamp opens the registration automatically and our team takes it from there.
