Setup for Thailand

It's nice to have new faces here the Community, @klausrauter.

QuickBooks Online aims to provide easy, straightforward ways to manage your accounting and finances. I'm glad you're able to see how the program can help run your business. I can answer all your concerns and assist you in setting them up. 

By default, the invoice form name will show as Tax invoice when printed or emailed. To ensure all sales receipts will also reflect Tax Receipts on them, you need to edit the form template. 

Here's how:

1. Go to the Gear icon, then Custom Form Styles. 
2. Click Edit in the default form template (Standard).
3. Select Content.
4. Click the first part of the sample PDF form. 
5. Under the Form section, change the Sales Receipt name to Tax Receipt (see screenshot 1). 
6. Click Done. 

After setting it up, open an invoice and a sales receipt, then check the Print Preview. They should show the form names Tax Invoice (invoice) and Tax Receipt (sales receipt). To do so:

1. From the Gear icon, choose Invoice/Sales Receipt.
2. Enter necessary information.
3. Select Print Preview. 

Now, for your second concern; are you referring to deleting some of the tax invoices created? If so, you simply have to open the invoice and manually delete it. Refer to the steps below:

1. Go to Sales in the left navigation panel, then Customers. 
2. Locate the customer you need. 
3. Open the invoice you want to delete, then click More at the bottom. 
4. Select Delete (see screenshot 2). 
5. Then, Save and Close. 

And for your last question; you'll want to enable the Custom Transaction Number feature in QuickBooks Online. This way, you can manually assign one transaction number (for example 921), and the rest will follow in order. 

1. Go to the Gear icon, then select Account and Settings.
2. Choose Sales in the left navigation pane.
3. Click the pencil icon in the Sales form content section.
4. Put a check mark on the Custom transaction numbers box (see screenshot 3).
5. Click Save, then Done.
