Products (required)

Using the interface
Sending sales invoices
Sales invoices are created normally, considering the maximum character limits listed below. In most cases, the system does not allow saving data exceeding the limits, except for the customer name - if the name is longer, the full data will not transfer to Passeli.
Customer name: 150 characters
Address: 100 characters
Postal code: 15 characters
City: 30 characters
Country: 2 characters
Business ID: 30 characters
Customer email: 80 characters
Invoice row description: 100 characters
Product name in product register / Show accounting section: 20 characters
You can send one or multiple sales invoices to Passeli at once from the top of the sales invoice list via
Print & Export > Send to Passeli Merit.
Assigning a product to an invoice row
Each invoice row must include a Passeli Merit product (called “item” in Passeli Merit), which automatically links the row to Passeli Merit sales accounts during transfer.
If a product on a Finago PSA sales invoice does not yet exist in Passeli Merit, it will be added to the Passeli Merit product register during transfer.
- Create the sales invoice with rows.
- Click Show accounting.
- Select the Passeli Merit product to assign to the invoice row.
In the example image, the default product defined in the settings is shown, which can be changed per row from the dropdown menu.
Receiving bills
Purchase invoices can be retrieved from Passeli to PSA for project expense tracking.
First, define in the interface settings whether to fetch all uncollected invoices once per day or only those with project information already defined in Passeli.
Purchase invoices are fetched every morning by 6 AM.
A purchase invoice is assigned in PSA to the default purchase invoice recipient without project allocation, unless one of the following allocation references is found (only one per invoice):
- If the invoice contains a PR/PRJ number (same as the PSA project’s E-invoice reference field), it is automatically assigned to that project and its project manager.
- If the invoice contains a PO number and a matching purchase order exists in PSA, the invoice is assigned to that purchase order, the related project, and its project manager.
- If the invoice contains a US number, it is assigned to the specified user.
