Lappa vs. Zamp

At Lappa, we lead the way in global compliance through our unified software platform. Specializing in comprehensive cross-border solutions, we offer services for VAT compliance, sales tax reporting, EPR registration and reporting, e-invoicing, marketplace tax management, and more.

Zamp is a fully managed sales tax compliance platform designed for modern digital businesses. After regulatory changes pushed enterprise-level complexity onto growing companies, Zamp was built to eliminate the burden entirely. Combining intelligent automation with a dedicated team of tax specialists, Zamp manages calculations, nexus tracking, registrations, filings, and state notices from start to finish. Unlike DIY tax software, Zamp owns both the work and the outcome, providing accuracy, predictable pricing, and ongoing support.
