This module enables contracts management with recurring invoicing
functions.
It works for customer contract and supplier contracts.
A rich set of reccurence patterns are available.
You can print and send contracts by email. Contracts are shown in
portal.
To view discount field in contract line, you need to set Discount on
lines in user access rights.
Contract templates can be created from the Configuration > Contracts >
Contract Templates menu. They allow to define default Journal,
Pricelist and Contract lines when creating a contract.
To use it, just select the template on the contract and fields will be
filled automatically.
Contracts are available in Invoicing > Customers > Customer Contracts
and Invoicing > Vendors > Supplier Contracts.
Click on New to create a new contact. Here is an overview:

- the partner (customer or supplier depending on the type of contract)
- the Journal is filled with the default customer/supplier journal
(first in sequence in Configuration > Journals)
- Pricelist, Payment terms and Fiscal position are filled in
from the partner information, if available
- Invoice every : Invoicing interval, in terms of days, weeks,
months, months last day, semesters or years
- Start Date of the contract, from which the invoicing period will
start
- End Date of the contract is optional. If not filled the invoice
generation will never stop.
- The Date of Next Invoice is automatically computed, but can be can
be modified manually
- Invoicing type : pre-paid or post-paid. A pre-paid contract
generates the invoice at the beginning of the invoicing period, a post
paid contract generates it at the end.
- Generation Type has only one option “Invoice”. Other options are
added in separate modules.
- Recurrence at lines level : see below
These lines will be used to generate the invoice lines. You can fill in
the product with a description, a quantity and a price.
The Description can include the markers #START#, #END# and
#INVOICEMONTHNAME# in the description field. This will display the
start/end date or the start month of the invoiced period in the invoice
line description.
Check Auto-price for having the price automatically obtained and
updated from the price list.
Recurrence at lines level is a different “mode”, where each contract
line has it’s own recurrence properties. For instance, one line starts
on 02/02/2026 and is invoiced every 2 weeks, and another line starts on
04/04/2026 and is invoiced yearly.
However, this mode and offers more reccurrence features, besides those
already presented.
Contract lines are now opened in a form view.

Auto-renew : contract lines will be automatically renewed when the
End Date is reached. The End Date will be postponed by the duration
set in the Renew Every field.
The field Termination Notice before will set the duration before the
End Date when the contract line state will change from In Progress
to Upocoming close. By default, the state changes one month before the
End Date.
Lines can also be manually renewed in advance using the green Renew
button.

You can Stop a contract line using the red button at the right.
A pop up will open asking for an Stop Date. In a pre-paid contract,
this date must be after the end of the period already invoiced. For
instance, if the last invoice covers the period from 01/01/2026 to
31/01/2026, the stop date must be equal or after 31/01/2026.
You can also Stop and plan a successor. A popup will ask for a new
Start and End date. The contract line will be stopped and a new one will
be created with the given Start and End dates.
The Generate Recurring Invoices from Contracts cron, available in
Settings > Technical > Automation > Scheduled Action, runs daily to
generate the invoices. Execution time and frequency can be configured in
the cron settings.
If you are in debug
mode,
you can click on the Create Invoices button.

The Show recurring invoices shortcut on contracts shows all invoices
created from the contract.
The menu Invoicing > Reporting > Contracts > Customer Contract
Lines/Supplier Contract Lines allows to view all contract lines in a
list view. Lines can be edited from there. Note : pivot view is not
available in this report.
The contract pdf report can be printed from the Print menu.
The contract can be sent by email with the Send by Email button
