Start here

In plain words: Hosting, support, rent, a licence: the same invoice every month, typed again by somebody who has to remember. Recurring Invoices & Contracts turns it into a contract: the lines, the period and the customer (or the vendor), and the invoice is created, posted and even sent on its date. You also see the monthly recurring revenue of all your contracts.

The contracts, one contract and the invoices it created.

Tip: Missed a few periods because the contract was started late or the server was off? The scheduled action catches them up.

What you get

Feature	What it does
Contracts	A partner, lines (product, quantity, price, discount, taxes) and a period: every n days, weeks, months or years.
Customer invoices and vendor bills	A contract creates either; a vendor contract is the rent or the internet bill.
Scheduled action	Creates the invoices that are due each day and catches up the missed periods.
Post and send	The invoices can be posted automatically and emailed to the customer.
Price increase	A percent applied to the prices every n months (12 for a yearly increase).
Control	Start, pause, resume, close, and create the invoice now.
Revenue	The amount of an invoice, per month and per year, with totals in the list.
Traceability	Each invoice shows its contract; the contract lists its invoices and keeps a log.
Arabic	Everything is translated and works right to left.

A contract

In plain words: Invoicing → Customers → Recurring invoices → New (or Vendors → Recurring bills). Choose the partner, the lines and the schedule, then press Start.

The contracts with their monthly and yearly recurring revenue.

Field	Meaning
Every	The period: for example 1 month, 3 months, 1 year.
Next invoice	The date of the next invoice; it moves on by one period at each invoice.
Ends on	After the last period the contract closes by itself. Empty: it goes on.
Post the invoices	Otherwise the invoices stay in draft for you to check.
Send the invoices by email	Customer invoices only, once posted, to the email of the partner.
Price increase	The percent and the number of months between two increases.

The invoices

In plain words: Each period creates one invoice dated on the period, with the period in the description of the lines and the contract as origin. The Invoices button of the contract lists them.

An invoice created by a contract: the period is in the description.

The vendor contracts: rent and internet.

Pause, close and the rest

A paused contract: the scheduled action skips it.

Button	What it does
Start	The contract runs from its start date.
Create the invoice now	Creates the next invoice immediately and moves the date.
Pause / Resume	No invoice while paused; when resumed, the missed periods are created.
Close	Ends the contract.
Back to draft	Reopens a closed contract.

A yearly contract: 4 licences a year, 1,200 per month recurring.

Who can do what

Who	Can
Accounting readers	See the contracts.
Billing users	Create and run contracts.
Advisors	Also delete contracts.

Arabic and right to left

Limits

Limit	Detail
Fixed lines	A contract repeats the same lines; usage-based billing is not computed.
Company currency	Invoices are in the currency of the company.
Catch-up	Up to 24 missed periods are created per run.
Email	The standard invoice email of Odoo is queued; its sending follows your outgoing mail settings.

For developers

In plain words: Skip this chapter if you only use the module.

contract = env['taqnix.recurring.contract'].create({'partner_id': partner.id, 'start_date': '2026-01-01',
    'line_ids': [(0, 0, {'product_id': product.id, 'quantity': 1, 'price_unit': 100})]})
contract.action_start(); contract._generate()   # or wait for the scheduled action

Troubleshooting

Problem	What to do
No invoice was created	The contract must be Running, with a next date on or before today.
“The invoice … could not be created: see the log”	Open the server log: a missing account, journal or tax is the usual cause.
The email is not sent	The partner needs an email, the invoices must be posted, and outgoing mail must be configured.
Too many invoices after a late start	Set the next date of the contract to the first date to invoice before starting.

Updating and removing

Replace the folder with the new version, restart Odoo and run -u taqnix_recurring_invoices. Contracts and the invoices they created are kept.
