Account Banking Mandate

This module adds a new "Banking Mandate" record that represents a customer's signed authorisation for your company to debit their bank account. You can create mandates from the Accounting menu under Receivables, or directly from a partner's bank account form, where a "Direct Debit Mandates" section is shown.

Each mandate has a reference (auto-numbered starting with BM), a format, a type, the linked bank account and partner, the signature date, an optional scanned copy, the date of the last debit, and a status: Draft, Valid, Expired or Cancelled. Buttons let you Validate, Cancel, and send a cancelled mandate Back to Draft. A smart button shows how many payment lines use the mandate.

Business rules are enforced automatically: - A mandate cannot be validated without a signature date and a bank account. - The signature date cannot be in the future, and the last debit date cannot be before the signature date. - References must be unique per company. - A payment line's bank account must match the mandate's bank account, and the mandate must belong to the same company.

On customer invoices, when the payment method requires a mandate, a Direct Debit Mandate field appears and is filled with the partner's first valid mandate. Payment lines for incoming payments must have a mandate when the method requires it. Partners show a count of their mandates and their first valid mandate, and bank accounts list their mandates.
