Our verdict on Zamp
Zamp is a managed sales-tax compliance platform for growing digital businesses, including e-commerce, SaaS, and digital services companies. It combines rooftop-accurate tax calculation, real-time address validation, product-level taxability rules, nexus monitoring, registrations, filing, remittance, notice management, and audit support. Its web and API access suit teams that need either an operational compliance service or custom tax workflows embedded in their own products.
The plan structure covers different stages of tax assessment and ongoing compliance. Free includes one-time nexus analysis, historical liability exposure estimates, product taxability review, a 30-minute expert consultation, and a rate-limited API sandbox. Assess and diagnose adds one-time nexus and product taxability assessments, historical liability analysis, expert consultation, and an API sandbox environment. The U.S. tier adds calculations, nexus monitoring and registration, automated filing and remittance, notice management, and dedicated U.S. tax expertise. U.S. + Canada includes those U.S. capabilities plus Canadian GST, HST, PST, and QST calculations, registrations, filing, reporting, and cross-border tax expertise. A 30-day trial is available, while the pricing model is contact sales.
Platform fit is a major strength. Zamp integrates with Shopify, BigCommerce, Adobe Commerce, WooCommerce, Stripe, Amazon, eBay, Etsy, QuickBooks Online, Xero, NetSuite, Microsoft Business Central, Chargebee, Cin7, and Checkout Champ. The API supports calculations, transactions, address validation, registrations, and filings. Businesses seeking automated U.S. or Canadian sales-tax operations should consider Zamp, especially when managed filing, notices, and audit support matter. Teams wanting a self-serve paid checkout or compliance coverage outside its supported tax scope should compare alternatives.
