I want to keep an accurate account of my overtime hours so I have a total of hours in lieu owed at the end of every week .is there a way

Yes, there's a way to track overtime hours for time off in lieu and present them on your client's invoice without charging for them immediately.

You can set up a service item and add it as a line item with a £0.00 rate. Here's how:

1. Go to All apps, look for Sales and get paid, then click Products and Services.
2. Click New product/service, then choose Service.
3. Add all the necessary details.
4. Click Save and close.

After that, use these steps on how to add the overtime hours in the weekly invoice:

1. Choose the service item you created for the overtime hours (in lieu).
2. Proceed to the Quantity column and indicate the number of overtime hours worked that week.
3. Set the Rate / Amount to £0.00 so the client isn't billed for them.
4. You may add a description such as "3 hours worked in lieu. Total cumulative TOIL owed to date: 12 hours."
5. Add all the details that are needed for the invoice before sending it to your client.
