E-commerce clients can create sales tax work faster than many CPA firms expect.
One online store becomes multiple sales channels. Then come marketplace reports, state registrations, filing frequencies, local rates, exemption questions, and late client data. The work is not impossible, but it needs a system.
A multi-state sales tax workflow helps CPA firms manage recurring compliance without rebuilding the process every month.
