Learn how Zamp automates sales tax compliance, from nexus monitoring to filing and remittance, plus its pricing tiers and how it compares to alternatives.
Zamp is a fully managed sales tax compliance company founded in 2022 by CEO Rohit Bhadange and Edward Lando, headquartered in San Francisco, California. Rather than offering only self-serve software, Zamp pairs its platform with a team that includes former state tax auditors to handle sales tax compliance end to end for e-commerce and SaaS businesses.
Zamp is backed by investors including the CEOs of ThredUp, Lands End, Kayak, Italic, and Drizly, and has raised over fourteen million dollars according to founder interviews.
The platform covers the full compliance lifecycle across the US and, more recently, Canada, from nexus monitoring through calculation, registration, filing, and remittance.
Zamp calculates sales tax with rooftop-accurate, geospatial rate determination and real-time address validation, and proactively monitors nexus thresholds across states so businesses know before they trigger a new filing obligation.
The platform automates state registrations and account setup, uses AI to assist with return preparation, and remits collected tax directly via ACH to state authorities, removing manual filing work from finance teams.
Zamp also handles notice management, with daily monitoring of state tax portals, and has expanded into Canadian sales tax coverage, including GST, HST, PST, and QST calculations, Canadian threshold monitoring, and cross-border tax expertise.
Zamp offers a Free plan for businesses that want to understand their tax exposure, including a one-time nexus analysis, a historical liability exposure estimate, a product taxability review, and a thirty-minute expert consultation.
Beyond the free tier, Zamp's U.S. Plan and U.S. plus Canada Plan are both custom-priced and require a sales conversation, since the company scopes pricing to each business's actual multi-state or cross-border compliance footprint rather than charging flat per-filing fees.
This all-inclusive, quote-based pricing model is designed to avoid the overage fees and hidden add-ons that Zamp argues are common with flat per-state or per-filing pricing used by some competitors.
