How to add sales tax depends on what accounting software your account syncs with.
QuickBooks for Windows
Set up sales tax in QuickBooks using sales tax items, rates, and codes. The next time the sync is run, we will bring over the sales tax items into Bill.com. Then as invoices are created in Bill.com, we will show and calculate sales tax.
Sales Tax Rates sync from QuickBooks Online to Bill.com, and invoice sales tax sync in both directions.
Xero, Intacct and NetSuite
Create a sales tax item in Bill.com. Then as invoices are created in Bill.com, we will show and calculate sales tax.
Other or No Accounting software
For accounting softwares that we do not have a direct integration with or if not using accounting software at all, create sales tax items manually or import your sales tax items.
