Positioning guardrails
Best for
- Growing e-commerce and DTC brands that want multi-state US sales tax filings handled end to end
- SaaS, fintech and digital-goods companies with subscription or marketplace revenue
- Lean finance teams that prefer a managed service with a dedicated account manager over DIY software
- Teams expanding into Canada that need GST/HST/PST/QST registrations and filings alongside US returns
Ideal size: 10–500 people · Scale-up with multi-state (or US+Canada) sales and a small finance team
Not for
- Enterprises that want to keep sales tax filing fully in-house with an internal tax department
- Buyers who require published flat or per-filing pricing before talking to sales
- Businesses whose sales tax exposure sits mostly outside the US and Canada
- Teams looking for a pure self-serve calculation tool with no managed service attached

Bottom line
Zamp is a managed sales tax service for growing US and Canadian digital businesses, combining rooftop-accurate calculation software, a REST API and integrations (Shopify, NetSuite, QuickBooks, Stripe and 30+ more) with tax professionals who handle registrations, filings, remittance and notices. A free assessment tier and 30-day API sandbox lower entry risk; paid U.S. and U.S.+Canada plans are scoped by footprint and quoted by sales. Buyers wanting published list prices or fully in-house filing should look elsewhere.
Frequently asked questions
What exactly does Zamp handle for our finance team?
Zamp combines sales tax software with a managed service: rooftop-accurate rate calculation at the building-address level, nexus monitoring, state registrations, return preparation and filing, ACH remittance, and end-to-end notice management. Customers describe spending minutes rather than hours per month on sales tax, with filings handled across 15 to 44+ states.
How is Zamp priced, and why is there no public list price?
There is a free tier for nexus and exposure assessment plus a 30-day API sandbox. The U.S. and U.S.+Canada plans are scoped to your jurisdictions, entities and systems and quoted by sales; Zamp argues flat per-state or per-filing pricing hides risk and states there are no per-transaction fees, with registrations, filings, notices and support included.
How long does implementation take?
Zamp runs white-glove onboarding with a dedicated specialist who handles data migration, account setup and existing state registrations. API users can make a first calculation within minutes using the free sandbox; production platform access is configured around your products, entities and integrations, so plan on roughly two to four weeks.
Which systems does Zamp integrate with?
Roughly 37 platforms are listed, including Shopify, BigCommerce, WooCommerce and Adobe Commerce, NetSuite, QuickBooks Online, Xero and MS Business Central, Stripe and Chargebee, plus Amazon, eBay and Etsy marketplaces. Sage Intacct, Acumatica, Zoho, Recurly and SAP are listed as coming soon, and a public REST API covers anything else.
What happens if a filing is late or wrong?
Zamp states it owns the outcome: under the Zamp Commitment, if a Zamp-managed calculation or filing results in penalties or interest, Zamp covers the cost. Notices are monitored daily across state portals and resolved by former state auditors and tax specialists, with a searchable notice and audit archive.
Does Zamp use AI, and what happens to our data?
The pricing page lists AI-powered return preparation and submission and AI-assisted notice classification, and Zamp describes deploying AI agents alongside tax professionals. The privacy policy says personal data is used to provide and improve the service; it makes no statement about training AI models on customer data, so confirm that directly with Zamp.
