Hello Katz67,
Thanks for posting in the Community!
If you want to allocate new payment terms to your invoice, you'll need to update the due date of the invoice. Once you've made this change, the invoice will automatically follow the last terms that were set when you create a new invoice.
- Go to Invoice tab.
- Click on New invoice.
- Locate the Due date and set a new terms date.
- Fill out other invoice fields.
- Click on Save.
When you create a new invoice, the new terms will automatically be followed.
Post again in the Community if you have further concerns. I'll be around to help you.
