Sometimes it is required to edit a job which has already been invoiced. In such cases, you have few options to reflect these changes in an existing invoice.

1. Open an invoice, select a job in the Invoice details table, and click Reload job data button on the toolbar. New amount will be loaded from a job, and invoice total amount will be automatically re-calculated.
2. When editing a job, select drop-down button near Save options button and select Save and add to existing invoice. If a job has multiple invoices, you will see a list to select which invoice you wish to update. After that, a job will be saved and underlying invoice will be updated. It is recommended to open an invoice and check if new amount is correct.
3. After editing a job, just select Save. If this job has been previously invoiced in full (and if only one invoice exists for that job) and the job amount has been changed, the system will offer to make corresponding changes in an linked invoice. Select Yes, and amount of invoice will b updated. Again, after such automatic change it is recommended to open an invoice to confirm that everything is correct.
