Merchant Problem
Sales tax gets messy when every channel has a different report.
- Storefront, marketplace, and payment reports do not always match
- New-state nexus can sneak up as sales grow
- Registration, collection, filing, and due dates are easy to lose track of
- State portals and confirmations create too much admin work
- Big tax platforms can be too expensive for lean teams
