About
Your clients trust you with their books, so you're the first call when they start selling into new countries and hit a wall of foreign VAT, GST, OSS/IOSS and sales-tax rules. Saying "that's outside what we do" risks the relationship. This session shows accounting firms a better answer: partner with a specialist indirect-tax provider and keep your client relationship intact while someone else carries the cross-border compliance load.
When
Wednesday, August 5, 2026 · 1:00 p.m. Eastern Time (US & Canada) (GMT -4:00)
Agenda
  • Why accountants are the natural first responders for cross-border tax questions - and what it costs the relationship to turn those questions away
  • The compliance landscape at a glance: VAT registrations, periodic returns, OSS/IOSS, GST and US sales tax for ecommerce sellers
  • Becoming the single point of contact: growing wallet share and client loyalty by delivering everything "from one hand"
