Zamp: cost, fit and limits
Zamp is a sales tax compliance platform made by Zamp, based in Miami, that assesses nexus, calculates tax, registers sellers, prepares returns with AI and files them in the United States and Canada. Its free tier includes a one-time nexus analysis and a 30-minute expert consultation.
What to know first
Zamp offers three plans named for coverage, not for size: Free, U.S. and U.S. + Canada. Free is an assessment and sandbox, the two paid plans add calculation, registration, filing and notices, and the page publishes no dollar amounts. Zamp says pricing is scoped to your footprint with no per-transaction fees. It claims 1,200 or more finance and accounting teams and a 4.7 rating on G2, both its own statements. The plan comparison names AI in return preparation, filing submission and notice classification.

Founders wanting a free first look
Free includes a nexus and exposure assessment, a product taxability review and a 30-minute expert session, which gives a concrete list of states before anyone signs.
NetSuite and Business Central users
The page lists NetSuite, Microsoft Business Central, QuickBooks Online and Xero among its accounting and ERP connections, next to Shopify, BigCommerce and Stripe.
Developers testing the API

What Zamp does
- Rooftop-accurate calculation
- The U.S. plan lists address-level rates rather than ZIP-level averages. That reduces over- and under-collection in cities where jurisdictions overlap within one ZIP code. Pricing from Zamp and its limits can shift, so recheck.
- Early-warning alerts
- Zamp sends alerts at 80 percent of a threshold, which leaves time to register before a state limit is crossed. The page lists the 80 percent figure but not the alert channel.
- AI return preparation
- Returns are prepared and submitted with AI on the U.S. plan, according to the plan table. The page does not state a review step, so ask who approves before submission.
- AI notice classification
- Letters from tax authorities are classified with AI assistance, which sorts routine requests from ones needing a response. It is listed under notice management. Nothing about Zamp on this point was tested here.
- Zamp API
- A Zamp API sits beside the connectors for stores and billing systems, so a custom checkout can call tax calculation directly. The free sandbox lasts 30 days and comes preloaded with all remote-seller state registrations.
How Zamp handles your data
Zamp states SOC 2 Type II compliance and links to a Trust Center at trust.zamp.com, which was not opened for this page. Its privacy policy lists the company address as 3165 Center St in Miami, says data is processed at its offices and wherever involved parties are located, and does not name a hosting region, sub-processors or any AI training practice. The vendor's policy was not checked for AI training beyond that, so a buyer should ask for it in writing and read the Trust Center report.
Where Zamp falls short in practice
- No dollar figures at all. Neither paid plan shows a price, only that fees depend on your footprint. A budget cannot be built from the page, and a seller must go through a call to learn if the cost fits.
- Coverage ends at Canada. Zamp's plans cover the US and Canada. A business that must register for VAT in the EU or UK needs a second provider, which splits filings and data across two vendors.
- AI review steps not described. The page names AI in return preparation and filing submission but does not say whether staff check each return, so the accountability for an error is unclear until the contract states it.

Alternatives to Zamp
Zamp: common questions
What does Zamp's free plan include?
Free offers a nexus and exposure assessment, a product taxability review, a 30-minute expert session and a rate-limited 30-day API sandbox. It does not register or file. That makes it a way to learn which states matter before choosing between the U.S. and U.S. + Canada plans.
Does Zamp charge per transaction?
The pricing page says there are no per-transaction fees and that pricing is scoped to your footprint, quoted after a short call with a tax expert. No dollar amount is published, so the cost depends on how many jurisdictions and filings you have.
How many integrations does Zamp list?
The page refers to more than 30 integrations, naming Shopify, Adobe Commerce, BigCommerce, WooCommerce, NetSuite, Business Central, QuickBooks Online, Xero, Stripe and its own API. Zamp gives no figure for this on the pages read. The U.S. plan adds rooftop-accurate calculations, automated registrations, filing and remittance and notice management.
Is Zamp a good fit outside North America?
The three plans cover the US and Canada only, so a seller with European or Asian tax duties would need another provider for those. Zamp's pages read do not mention VAT filing in other regions. The U.S. plan covers states and territories, and the U.S. plus Canada plan adds GST, HST, PST and QST calculations and Canadian filings.
What AI does Zamp use for tax filing?
The plan table lists AI-powered return preparation, AI-powered filing submission and AI-assisted notice classification. The page does not name a model or describe human review, so ask how a prepared return is checked and by whom before it is filed.
