# Editing Invoicing Months

### Editing Invoicing Months

Invoicing months are defined in the first version of your workplan and cannot be changed through a revision process once the workplan has been approved.

If your program has zero expenses on a given invoicing month, submit the invoice with zero expenses. This ensures access to subsequent invoicing months. To add invoicing months that were not initially selected in your workplan, contact your Program Specialist.
