Extend Wave Accounting with Powerful U.S. Sales Tax Filing, Monitoring, and Automation

Wave is a popular free accounting platform trusted by freelancers, solopreneurs, and small businesses for invoicing and expense tracking. But if you’re generating income from U.S. customers, Wave’s built-in tax features fall short, offering basic rate application but no automated nexus tracking, no multistate filing, and no consolidated compliance. Commenda’s sales tax plugin for Wave fixes that. It connects directly to your Wave account, pulls your transaction data, calculates the right U.S. sales tax for every invoice, and handles all your jurisdictional filings, from New York to California. If you’re running a service business, SaaS, or online store using Wave and expanding into the U.S., Commenda ensures you remain compliant while staying focused on growth.

Who Should Use Commenda’s Wave Integration?

Commenda is ideal for:

  • Freelancers and consultants billing U.S. clients via Wave
  • SaaS startups or solopreneurs offering digital services
  • Agencies using Wave for simple bookkeeping but needing U.S. tax compliance
  • Canadian or international Wave users entering the U.S. market
  • Any business using Wave that’s exceeded or nearing U.S. sales tax nexus thresholds

If you’re invoicing across borders with Wave but struggling with sales tax obligations, Commenda automates it all, without leaving the tools you know.
