Numeral review

Numeral is built around handing off the filing work. The free Monitoring plan connects your stores or billing tools, runs a nexus study, watches physical and economic nexus and alerts you when you cross into a new jurisdiction. Professional charges $75 per return filed and a one-time $150 per state registration, and adds registrations, filings and remittance, Autofile, Autoregister, a virtual mailbox for tax mail, AI product classification, exemption certificate management and a concierge team. Numeral states there are no setup fees and no per-transaction overages on standard US filings, and accounts run month to month. Its guarantee says that if a return is not filed on time, Numeral pays the penalties and interest. Enterprise adds coverage in 90+ countries, the tax engine and API with 140ms p95 latency, and access to tax lawyers. The cost is easy to predict, though a seller filing monthly in ten states would pay $750 a month in filing fees.
