Zamp in brief

Zamp publishes no prices and explains why on the page.

Price: None, quote only. Both paid plans say contact sales · Scoped subscription with registrations, filings and notices included, no per-transaction fees
Best for: Growing ecommerce, SaaS and digital service businesses with no in-house sales tax owner
Watch out for: You give up the ability to compare on price, and Zamp has decided that for you.

The short answer

Buy Zamp if you want sales tax taken off your desk rather than made easier to do yourself. Registrations, filings, remittance, notice handling and white-glove support are described as included rather than billed per item, there are no per-transaction fees, and the Zamp Commitment says that if a Zamp-managed calculation or filing results in penalties or interest, Zamp covers the cost. For a finance team of one or two running a growing US or US and Canada footprint, that is the whole case.

Skip it if you need a published price to compare, because neither paid plan carries a figure and Zamp says plainly that it will not list per-state or per-filing rates. Skip it if you want to operate the tool in-house and would rather pay less for software than more for a service. And skip it if you sell outside the US and Canada, since those are the two geographies the plans cover.

Where Zamp fits

Zamp sells a service with software attached, and it is explicit about the distinction. The homepage offers two models: done for you, where Zamp handles registrations, filings, notices and support, or done with you, where Zamp prepares the work and your team reviews and approves. That is a different proposition from a tax engine you configure yourself, and it decides fit faster than any feature comparison. If your problem is that nobody on your team wants to own sales tax, this is the shape of answer you are looking for. If your problem is that your checkout calculates the wrong rate, you may be buying more than you need.

The plan structure is geographic rather than functional, which keeps the choice simple. Free is an assessment, not a trial of the product. The U.S. plan adds rooftop-accurate calculation with real-time address validation, nexus monitoring with early-warning alerts, automated state registrations and account setup, AI-assisted return preparation with direct ACH remittance, early-filing discount capture, automatic filing frequency management, end-to-end notice management with daily state portal monitoring, and access to former state auditors. The U.S. + Canada plan adds GST, HST, PST and QST calculation with CAD support, Canadian threshold monitoring, provincial registrations, Canadian filings with input tax credit entry, a unified liability view and Canadian audit support.

The free plan is more substantial than most vendors' trials and it is the right place to start. It gives a one-time nexus analysis, a historical liability exposure estimate, a jurisdiction-by-jurisdiction risk summary, a product taxability review with classification and edge-case handling, a 30-minute session with a senior sales tax professional, and a rate-limited 30-day API sandbox preloaded with remote-seller state registrations that cleans itself up afterwards. Take all of it before you negotiate: the exposure estimate is the document Zamp will scope your price against, so you want to read it first.

Historical exposure is where this product earns its keep and also where the quote comes from. Zamp says a short assessment is needed because prior providers frequently left gaps that have to be addressed upfront, and the free assessment is designed to surface them. Back filings, registrations you should have made and taxability decisions someone got wrong are the expensive part of switching sales tax vendors, and they sit inside Zamp's scoped price rather than on a rate card. Which means the cleaner your history, the better your quote, and the messier it is, the more of the value you are buying.

The operational details worth checking are the ones that bite in month three rather than month one. Notice management is end to end with daily state portal monitoring, AI-assisted classification, expert resolution and a searchable archive. Reporting includes liability by jurisdiction, GL-ready reconciliation reports, audit-ready transaction history and multi-entity support. Integrations cover Adobe Commerce, BigCommerce, Microsoft Dynamics 365 Business Central, NetSuite, QuickBooks Online, Shopify, Stripe, WooCommerce, Xero and the Zamp API. One thing to note on diligence: the pricing page footer says compliance for AICPA SOC 2 is in progress rather than complete, so ask where that stands and what evidence you can have in the meantime.

Zamp pricing

Zamp publishes no prices, and it is the rare vendor that says why. Checked on 16 October 2026, the pricing page names three plans, Free, U.S. and U.S. + Canada, compares every feature across them, and puts a contact sales action on both paid tiers. Zamp's own explanation is on the page: it says sales tax complexity varies widely by product mix, number of states, entities and historical exposure, that flat per-state or per-filing pricing often hides risk and leads to add-ons later, and that it scopes pricing to your actual footprint instead. Agree with that or not, it is a stated position rather than silence, and it tells you what the quote is a function of.

Four things set the figure, and the first two are the ones Zamp names itself.

Which of the two paid tiers you need. The split is geographic: the U.S. plan covers calculation, registrations, filing, remittance and notice management across US states and territories, and the U.S. + Canada plan adds GST, HST, PST and QST work, Canadian registrations and filings, input tax credit entry and Canadian audit support. That choice moves the bill before any volume question does.
Your scope, which Zamp defines as nexus, jurisdictions, entities and systems. It says plans are designed by stage of growth and then scoped to those four things, so the number of states and provinces you have obligations in, the number of legal entities and your product mix are what the price is built on. Get those counts written into the contract along with what happens to the price when you register somewhere new.
Your historical exposure. The free assessment produces a historical liability exposure estimate and a risk summary jurisdiction by jurisdiction, and Zamp says prior providers often left gaps that have to be addressed upfront. Back filings and clean-up sit inside the scoped price, so the state of your history is part of the quote rather than a separate project.
What is included rather than metered. Zamp says there are no per-transaction fees and no surprise invoices, and that registrations, filings, notices and white-glove support are included. So order volume is not the stated meter. The flip side is that the single included figure is the only number there is, and it exists only in your quote.

What costs extra

No add-on prices are published. Zamp says registrations, filings, notices and white-glove support are included rather than billed separately, which is the claim to test rather than accept.
Exemption certificate management and the white-label service are listed as further products with no price attached.
Back filings, amended returns and voluntary disclosure work are described as part of the scoped engagement. Ask explicitly whether they sit inside the included price or outside it.

Implementation and commercial terms

The rows below are what the Zamp pricing page confirms as of 16 October 2026. The Free plan is the only one with a stated price, and it is an assessment rather than access to the paid product.

Published price: None, quote only. Free, U.S. and U.S. + Canada, with both paid tiers sent to sales
Why no price: Zamp says flat per-state or per-filing pricing hides risk and leads to add-ons, so it scopes to your footprint
Pricing basis: Scoped to nexus, jurisdictions, entities and systems, with no per-transaction fees
Free plan: One-time nexus and taxability assessment, exposure estimate, a 30-minute expert session, a rate-limited 30-day API sandbox
Implementation fee: None published. Zamp describes white-glove onboarding with a dedicated specialist handling migration, setup and existing registrations
Guarantee: The Zamp Commitment: if a Zamp-managed calculation or filing results in penalties or interest, Zamp says it covers the cost
Security posture: The pricing page states compliance for AICPA SOC 2 is in progress

Budget Zamp as a managed service with one number, and do the free assessment before you discuss that number at all. The exposure estimate and the jurisdiction risk summary cost nothing and are the document your price will be scoped against, so read them first and decide which findings you want Zamp to fix. Then nail down the scope in the contract: the state and province counts, the entity count, the systems, and what happens to the price when any of them changes. Test the no-per-transaction-fee claim against a month when your order volume doubles, and get the Zamp Commitment written into the agreement with its limits spelled out rather than taken from the website. Because nothing is published, the only honest benchmark is a vendor whose rates you can read, so put TaxJar's published per-order prices or Avalara's per-state figures next to the quote and make Zamp justify the difference as a service, which is what it is selling.

What Zamp gives up

You give up the ability to compare on price, and Zamp has decided that for you. Neither paid plan carries a figure, and the page argues that per-state and per-filing rate cards hide risk. That argument has merit and it also means you cannot tell whether your number is standard, whether a similar company paid less, or whether your renewal is reasonable. The only remedy is a competitive process including at least one vendor who publishes, plus a negotiated uplift cap agreed before you become a reference customer.

You give up the US and Canada boundary. The plans cover US states and territories and, on the higher tier, Canadian federal and provincial taxes. There is no EU VAT, UK VAT or wider international layer in the published plan structure, so a business planning to sell into Europe inside its contract term is buying a tool it will have to supplement. That is a reason to look at a multi-country platform now rather than to negotiate harder here.

You give up control, which is the point and also the cost. In the done-for-you model Zamp performs the registrations, prepares and files the returns, remits by ACH and resolves the notices. That removes work and it also means your compliance record is produced by someone else's process. Ask for the audit trail you get, the GL-ready reconciliation reports, your rights to export transaction history, and what happens to in-flight registrations and open notices if you leave mid-year.

You give up a conventional trial. The Free plan is an assessment plus a rate-limited 30-day API sandbox that cleans itself up, not access to the paid product, and Zamp says full platform access is configured around your products, entities and integrations with sales involved. So you cannot run the real thing before a commercial conversation. Ask instead for a scoped onboarding milestone with written success criteria, and treat the request as a test of how the vendor behaves when you want something specific.

You give up a completed SOC 2 report, at least for now. The pricing page footer says compliance for AICPA SOC 2 is in progress. For a vendor that will hold your transaction history and file on your behalf, that is a real diligence item rather than a formality: ask where the audit stands, what period it will cover, what interim evidence you can have, and whether the contract commits to a completion date. If your security review will not accept an in-progress answer, resolve that before anything else.

How Zamp compares

US sales tax splits on who does the work and whether you can read a price. Zamp sells the managed version and publishes nothing for it, deliberately. TaxJar publishes a per-order rate card and expects you to operate it. Avalara publishes per-state figures below a revenue line. Kintsugi publishes two of its four plans and charges per action. Anrok could not be checked at all. Every price below comes from that vendor's own pricing page, checked on 16 October 2026, and anything unpublished is recorded as unpublished rather than estimated.

Tool	Best for	Price	Where it breaks
Zamp	Teams who want registrations, filings, remittance and notices owned by the vendor under one included price	Not published, quote only	No figure for either paid plan, US and Canada only, and SOC 2 compliance is stated as in progress
TaxJar	US multichannel sellers who want a published price and will operate compliance in-house	$39 / mo and $99 / mo, both at 200 orders a month	Filings are billed as AutoFile credits on top, and the flex fee for peak months is unpublished
Avalara	Sellers whose cost tracks registered states rather than order volume	$79 per state/month or $799 per state/year (Core Compliance)	Published plans stop at the $50M revenue line, above which it is a custom quote
Kintsugi	Teams who want to pay per action, with a genuinely free entry plan	Free $0, Starter $75 per action; Scale and Premium quoted	The API, SSO and real-time calculation sit on Premium, which publishes no figure
Anrok	SaaS sellers, though nothing could be verified about the current offer	Could not be accessed on 16 October 2026	anrok.com returned HTTP 403 to every request, so no price or feature claim could be read

What to test in a Zamp evaluation

There is no trial of the paid product, but there is a free plan that does real work: a one-time assessment plus a rate-limited 30-day API sandbox. Use it first, then treat the sales conversation as the second half of the evaluation. Five steps.

Run the free assessment before you talk about money. It produces a nexus analysis, a historical liability exposure estimate, a jurisdiction-by-jurisdiction risk summary and a product taxability review with edge cases. Read all of it. This is the document Zamp will scope your price against, so you want to know what it says before they quote against it.
Use the 30-minute expert session on your hardest taxability question, not a general briefing. Bundles, digital services, mixed offerings, a state where you suspect you have been wrong for two years. The session is with a senior sales tax professional, so bring the question your own team cannot settle and see whether the answer is specific or hedged.
Put your real integration through the API sandbox. It is rate limited, runs for 30 days, comes preloaded with remote-seller state registrations and cleans itself up afterwards. Test rooftop accuracy against addresses you know are awkward, check refund and credit note handling, and if you run Shopify, NetSuite, QuickBooks Online, Stripe or Business Central, verify the connector rather than the demo.
Test the included-price claim against your worst month. Zamp says there are no per-transaction fees or surprise invoices and that registrations, filings, notices and support are included. Ask what happens when order volume doubles, when you register in six more states mid-year, when a return has to be amended, and when a back filing is needed. Get each answer as a contract term rather than reassurance.
Close the commercial and compliance gaps together. Get the scope counts, nexus, jurisdictions, entities and systems, written into the agreement with the price effect of changing each. Get the Zamp Commitment in the contract with its limits spelled out. Ask where AICPA SOC 2 compliance stands and what interim evidence you can have. And agree exit terms: data export rights, and what happens to in-flight registrations and open notices if you leave.

Frequently asked questions about Zamp

How much does Zamp cost?

Zamp publishes no price. As of 16 October 2026 its pricing page names three plans, Free, U.S. and U.S. + Canada, and both paid plans say contact sales. Zamp says it scopes pricing to your actual footprint rather than listing a per-state or per-filing rate.

What is Zamp?

Zamp is managed sales tax compliance: software plus a team that handles nexus monitoring, registrations, calculation, filing, remittance and notice resolution across the US and Canada. It offers two models, done for you, where Zamp owns the work, and done with you, where Zamp prepares it and your team approves.

Why does Zamp not list prices?

Zamp answers this on its own page: it says sales tax complexity varies by product mix, number of states, entities and historical exposure, and that flat per-state or per-filing pricing often hides risk and leads to add-ons later. It scopes pricing to your footprint instead. Checked 16 October 2026.

Is there a free Zamp plan?

Yes, and it does real work. The Free plan gives a one-time nexus and exposure assessment, a jurisdiction-by-jurisdiction risk summary, a product taxability review, a 30-minute session with a senior sales tax professional, and a rate-limited 30-day API sandbox that cleans itself up afterwards.

Can I use Zamp without talking to sales?

Only partly. The Free assessment and the API sandbox are self-serve, but Zamp says full platform access is configured around your products, entities and integrations with sales involved. Both paid plans route to a contact sales action, so the real product requires a scoping conversation.

What is the difference between the U.S. and U.S. + Canada plans?

Geography. The U.S. plan covers rooftop-accurate calculation, nexus monitoring, automated state registrations, filing, ACH remittance and notice management. The U.S. + Canada plan adds GST, HST, PST and QST calculation, CAD support, provincial registrations, Canadian filings with input tax credit entry and Canadian audit support.

Does Zamp charge per transaction?

Zamp says no. Its pricing page states there are no per-transaction fees or surprise invoices, and that registrations, filings, notices and white-glove support are included. That makes the scoped price the only number, so ask what happens in a month when order volume doubles and get the answer as a contract term.

What happens if a filing is late or wrong?

Zamp publishes what it calls the Zamp Commitment: if a Zamp-managed calculation or filing results in penalties or interest, Zamp says it covers the cost. Ask for that in the agreement with its limits spelled out rather than relying on the website wording, since the scope of the guarantee is what matters.

Does Zamp handle state notices and audits?

Yes, on the paid plans. Notice management is described as end to end with daily state portal monitoring, AI-assisted classification, expert resolution and a searchable archive, alongside audit support and representation. The higher tier adds Canadian audit support and cross-border specialists.

Is Zamp SOC 2 certified?

Not yet, by its own statement. The Zamp pricing page footer says compliance for AICPA SOC 2 is in progress. For a vendor holding transaction history and filing on your behalf, ask where the audit stands, what period it will cover, what interim evidence you can have, and whether a completion date is contractual.
