Xpert-Timer Manual > Configuration > System

Sales tax rate	Customize the tax rate for your invoices here. It is not possible to save multiple tax rates in Xpert-Timer. If necessary, you must change them manually when invoicing.
Rounding mode	When creating an invoice, values with more than two decimal places may occur, which must be rounded for output. In Xpert-Timer, you have two different rounding options: round each invoice item or round the total amount.
Template	You can edit all fields of the invoice in the report generator. Please note that the template generator is an external program called FastReport. We cannot offer support for this product.
Next number	Here you can see the number that will be used to create the next invoice.
Length of RE no.	Specify here how many digits your invoice number should have. If you always want to assign 4-digit invoice numbers, enter 4 here.
Prefix	Set a prefix for your invoice number. This can consist of numbers and letters.

Your company

Here you can enter your own company details. If your company is based in Switzerland and you want to generate QR invoices via Xpert-Timer in the future, you must enter your company details here. It is important that you write out your street name in full, as the QR code misinterprets the abbreviation "str." You must also enter an IBAN so that your customer can successfully scan the QR code.

Customize invoice template

Yes, you can customize the invoice template in Xpert-Timer. With this report, you can influence all areas of the printout. Be careful not to change the SQL commands, as this will prevent your template from working. To be on the safe side, make a backup copy of the working template before making any changes.

The best way to design the template is to create three test invoice items in the "Invoices" tab. Save the invoice and then click on "Edit template." This will populate your template with data, allowing you to test the appearance much more effectively.

If you change column information, make sure that all 3 lines are changed accordingly so that the data is still displayed correctly.

You can change the labels by double-clicking on them.

Press F9 to display the preview and make any further adjustments.

Each time you click on an object in the template, you will see the properties for that object on the left-hand side. You can also customize these properties.

The data itself, i.e., the SQL commands and data bands, should be left as they are. If you delete a field, e.g., sqlinvoice."discountpercentage" (discount), you will receive an error message because this field is still referenced in the "Code" tab. It is better to set the fields you do not need to "Visible" -> False. This will hide this area. Remember to set the corresponding area to "Visible" -> False in all three lines so that the layout is correct when printing the invoice.

Save the template as XTINVOICE_* so that it appears in your invoice templates.

	The same applies here:
Save your template with a unique name to prevent an update from overwriting your template. If your template has been accidentally overwritten, you will find a backup in the program directory -> Backup -> Reports.
