Do you have a customer who would like to receive an invoice? Then that is easily arranged with Optios.
The first step is to enter your invoice details via
1. Settings
2. Account
3. Billing information: fill in and save.
Once this is in order, you can create an invoice from any account for any customer.
Once the account has been settled, you will see 'create invoice' at the bottom right.
When you click on this, you have to fill in and save the details of your customer.
You can check all invoices created via
