Hi there, nkadri.

I can help you change the VAT percentage from 5% to 15%. This can be done within the Tax page in your book. To guide you further, please follow the steps below:

1. Go to Taxes on the left panel.
2. At the upper-right corner, click the Edit drop-down arrow. 
3. Select Edits rates.
4. In the Tax Rates lists, find the tax name that you want to change.
5. Then, click Edit under the Action column.
6. Change the percentage and other details that needed to be changed. 
7. Once done, click the Save button.

In addition, we can add another percentage, which is 15% in the Invoice set up without changing the previous percentage. Here are the steps on how to do it:
 

1. Still within the Tax page, click Edits rates.
2. Click the Add tax rate button at the upper-right corner.
3. Enter the needed information such as the tax name, description, sales rate, and others.
4. Then, click Save.

Every time you want to add another VAT percentage, you can follow the same steps above.
