Retainer & Prepaid-Hours

Sell prepaid hour blocks and burn them down against timesheets with top-up alerts

Agencies that sell blocks of hours usually track them in spreadsheets and discover they've over-served only at month-end. This module ties a retainer contract to a project so every timesheet line (account.analytic.line) burns the prepaid balance down automatically — oldest block first. Consumed hours, remaining hours and a burn-rate update live; a configurable low-balance threshold flips the contract to "Low" and schedules a top-up activity, and a nightly cron flags expiring blocks and depleted contracts so nothing is delivered for free.

Key Features

Retainer Contracts

Per-customer contracts with period, hourly rate, optional linked project and a draft → running → low → depleted → closed lifecycle.

Prepaid Hour Blocks

Each top-up adds hours and value; blocks can carry their own expiry, and the set of blocks builds the total purchased balance.

Automatic FIFO Burn-Down

Timesheets on the linked project consume the retainer oldest-block-first, with consumed, remaining and burn-rate computed live per contract and per block.

Low-Balance & Expiry Alerts

A percentage threshold flips the contract to "Low" and schedules a top-up activity; a nightly cron flags blocks expiring soon and contracts that have depleted.

Consumption Log

Every timesheet entry links to the exact block it drew from, with employee, date, hours and value — a transparent audit trail of where the hours went.

One-Step Top-Up Wizard

Sell a new hour block in a single action, optionally creating a matching sale-order line value for invoicing.

Nothing Native Does This

Core Odoo has no prepaid-hours model, FIFO burn-down or top-up alerting — this tracks retainers end to end.

Stop Serving for Free

Live balances and proactive alerts mean you never silently over-deliver against a depleted block again.
