Zamp sells sales tax compliance as a managed service. Teams that look for a Zamp alternative usually want pricing they can see before a sales call, ongoing monitoring rather than a one-time analysis, or coverage beyond the US and Canada. This guide covers why sellers switch, six alternatives with published pricing, who each one fits, and how moving off Zamp works.

Why sellers look for Zamp alternatives
Kintsugi publishes its prices, keeps monitoring your exposure for free, and covers the US and 100+ countries. Here's where Zamp's published plans draw the line.
No published prices. Zamp's U.S. and U.S. + Canada plans require contacting sales. Zamp says it doesn't list fixed prices by state or per filing because sales tax complexity varies. Kintsugi's paid plans start at $75 per filing or registration, so you can estimate cost before you talk to anyone.
A one-time free plan. Zamp's free plan is a one-time nexus analysis, not ongoing monitoring. Kintsugi's free plan is ongoing, with global exposure monitoring, nexus threshold alerts, AI product categorization, and address validation.
US and Canada only. Zamp covers the US, with Canada on its U.S. + Canada plan. Kintsugi's Premium plan covers Canada, the EU, the UK, and 100+ countries.
Limits on the Zamp Commitment. Zamp covers penalties or interest from Zamp-managed calculations or filings on its managed tiers. For API customers, coverage of an inaccurate result is capped at the amount paid over the prior 12 months. The Kintsugi Guarantee, on Premium, covers penalties or interest caused by our calculation or filing errors.

The 6 best Zamp alternatives
1. Kintsugi
Kintsugi is an AI-native sales tax, VAT, and GST platform for growing SaaS and ecommerce companies.
- Pricing: A free plan includes global exposure monitoring, historical liability auditing, nexus threshold alerts, AI product categorization, and address validation. Starter begins at $75 per filing or registration and adds automated registrations, filings, remittance, refunds and amendments, deregistration, and a virtual mailbox. Premium is custom, with volume discounts. See pricing.
- Coverage: 13,000+ US jurisdictions, plus Canada, the EU, the UK, and 100+ countries on Premium.
- Integrations: 60+, including no-code Shopify, Stripe, Chargebee, and BigCommerce connections.
- Support: Onboarding assistance and 24/7 live chat with same-day human responses on Starter; dedicated onboarding and account teams on Premium.
Best for: Sellers that want filings handled for them with published pricing and ongoing monitoring.
2. Numeral
Watch for: Registration costs $150 per state, twice Kintsugi's starting price. Global coverage is on the custom Enterprise plan. Numeral's guarantee covers late filings only. See our Numeral alternatives guide.
Numeral also publishes per-filing pricing ($75) and offers free monitoring, autofile, and a virtual mailbox.
Best for: US-focused sellers that can pay $150 per registration and don't need global coverage outside an Enterprise contract or a guarantee beyond late filings.
3. TaxJar
Watch for: TaxJar is US only and isn't a managed service. Each plan includes two or four AutoFile filings a year before extra filings cost $50 to $55. TaxJar's Starter plan has doubled from $19 to $39 a month since early 2025, and TaxJar no longer supports new NetSuite integrations. See our TaxJar alternatives guide.
Best for: US-only ecommerce sellers under 200 orders a month that file in only a few states and handle their own registrations.
4. Avalara
Watch for: Avalara prices each state separately, from $79 per state per month, for companies under $50M in revenue, and charges $403 per registration. Avalara lists 1,400+ integrations, but fewer than 80 are built by Avalara; the rest are built and maintained by third-party partners. Avalara sells live chat, phone support, and faster responses as separate Priority and Enterprise Support plans, and sells hands-on Guided Implementation separately too. See our Avalara alternatives guide.
Best for: Companies above $50M in revenue that need several tax types from one vendor and will negotiate a custom quote, per-state pricing, and separately sold implementation and support.
5. Anrok
Watch for: Every state or country is a separate $100-a-month market on Starter, and Anrok doesn't publish an error guarantee. See our Anrok alternatives guide.
Best for: SaaS companies in a handful of markets that can absorb $100 per market, per month, with no published error guarantee.
6. TaxCloud
Watch for: TaxCloud is US only, prices by order volume, and adds surcharges for Colorado, Louisiana, and Washington B&O filings.
In the 24 Streamlined Sales Tax states, eligible sellers can get registration, calculation, filing, and remittance at no cost through TaxCloud. See our TaxCloud alternatives guide.
Best for: US-only sellers whose obligations sit mostly in SST states and whose order volume stays in a low pricing tier.

How to switch from Zamp to Kintsugi
- Connect your channels on the free plan. Use Kintsugi's no-code integrations or import transactions by CSV. Exposure monitoring and historical liability auditing show where you have nexus today.
- Collect your registration details. Your registrations belong to your business, so they carry over. Ask Zamp for your state account details and filing history.
- Plan around your contract. Our team reviews your filing calendar and Zamp agreement and picks the first filing period Kintsugi owns in each state, so nothing is filed twice.
- Connect state accounts and notices. Kintsugi files and remits, and its virtual mailbox collects state notices.
- Register where you're newly exposed, from $75 per registration. Premium adds back filing with voluntary disclosure agreement (VDA) options.
