This module adds a formula to compute prorated quantity to invoice as extension of the module contract_variable_quantity.
auto_awesome What this module does
AI-generated from the code · Odoo 19.0Adds a "Prorated Quantity" formula for contract lines, so invoices can bill a quantity proportional to the days actually covered in the invoicing period.
This module extends the contract variable quantity feature with a new quantity formula called "Prorated Quantity". When a contract line uses this formula, the quantity to invoice is calculated as the line's quantity multiplied by the share of the period that is really invoiced.
The calculation compares the real invoicing period with the theoretical one. It takes into account the recurrence type (for example monthly, monthly last day, daily), the recurrence interval, and whether invoicing is pre-paid or post-paid. For monthly-last-day contracts with post-paid invoicing, the calculation adjusts the theoretical period accordingly. The result is a ratio of invoiced days, which is then applied to the line quantity.
On contract templates, the quantity field is hidden and made required, because the quantity is now driven by the formula rather than entered manually. The module works on contract.line and contract.template.line records and depends on contract_variable_quantity.
