Questions about the buyout.
Still have questions? Call us at 1-866-438-9267 or email us at support@zamp.com.
Is there a catch?
No. We cover your remaining commitment and you switch to Zamp. We do it because once finance teams have someone else owning the outcome, they don’t go back. Over 500 companies have made the switch.
Which providers does the buyout cover?
Any sales tax software or service you’re under contract with, from Avalara and TaxJar to Kintsugi, Numeral or an outside firm. Tell us who you use and what’s left on your term.
What if I’m only a few months into my contract?
The buyout applies whether you’re 2 months in or 10. We’ll structure the credit around your remaining commitment.
How does the buyout work?
Tell our team about your current contract, including your remaining term and what you’re paying. We review it and put together an offer, typically a credit applied to your Zamp subscription, so you don’t pay twice.
Will switching disrupt our filings, close or audits?
No. Your setup is reviewed, validated and migrated in parallel, so filings, registrations and reporting continue without interruption. Your old account goes offline only after our tax team confirms everything is live and accurate. Most teams switch within a week.
How does Zamp’s pricing work?
One fee for the whole outcome: filings, registrations, nexus monitoring, notice management and a named specialist. No per-return fees, no per-state surcharges, no surprise add-ons as you grow.
Switch without paying twice.
Bring your contract, your states and your systems. A sales tax specialist will put together your buyout offer and show you what Zamp takes over.
