I'll be happy assisting you on how to add a sales tax rate within your transaction including estimates, invoices, and sales receipts in the Android app, Rachel
When you already add your sales tax rate, you should be able to add it to your sales transactions.
Here's how:
- Select the Estimate or Invoice with the sales tax rate you want to add.
- Then click the Add product and services.

- Then select the item and then from their you can add your Tax rate.

- Then hit Save to apply the tax to the invoice.
