Set rates

Choose which rate TimeToBill uses and how to edit an invoice line manually.

Updated: 2026-04-25 Nederlandse versie

TimeToBill can use rates from different sources. You choose which source has priority in Settings -> Rates and invoicing.

Possible rate sources

TimeToBill can work with:

a rate from your time tracker;
a rate from your accounting or invoicing software;
a default rate in TimeToBill;
a manual adjustment per invoice line.

Which sources are available depends on the connected providers and your settings.

Default rate in TimeToBill

A default rate is used when you work with one fixed hourly rate or when connected software does not supply a rate.

Set this in Settings -> Rates and invoicing.

Rate from connected software

If your time tracker or invoicing software makes rates available, TimeToBill can use them when building invoice lines.

Always check the draft invoice before sending it. You remain responsible for the correct rate on the invoice.

Use a client rate from WeFact

If you want to use a fixed hourly rate per client from WeFact, first create a custom field for customers.

Open WeFact.
Go to Settings -> Custom fields / Eigen velden.
Click Add field / Veld toevoegen.
Enter a field name, for example Hourly rate.
Under Applies to / In te vullen bij, select Customers / Klanten only.
Keep Type set to Text field / Tekstveld.
Click Add field / Veld toevoegen.

WeFact then shows the new field in the custom fields table. Copy the value from the Field code / Veldcode column, for example custom_1, and enter it in TimeToBill under Rates and invoicing.

Then enter the hourly rate for each customer in WeFact. Use only the amount, for example 95 or 95.00.

Edit the rate per line

You can edit the rate per invoice line before creating the draft invoice.

Use a manual adjustment for:

a one-off discount;
a different client agreement;
a missing rate;
a correction on a line.

A manual adjustment only applies to that invoice line. It does not change the setting for future invoices.

VAT, rounding, and unit

In the same settings, you also choose the default VAT percentage, hour rounding, and unit shown on invoice lines.
