+# Account Banking Mandate Batch Create
+
+Adds a contextual server action **Create SEPA mandates** to the Contacts
+(`res.partner`) list and form views.
+
+## Usage
+
+1. Go to *Contacts* (or *Accounting → Customers*), switch to list view.
+2. Filter the partners you want (e.g. your members: `is_client = True`).
+3. Select them (tick the header checkbox to select all).
+4. *Actions → Create SEPA mandates*.
+
+For each selected partner the action:
+
+- takes the partner's first bank account (`bank_ids[:1]`),
+- creates a recurrent SEPA Core mandate (`format=sepa`, `type=recurrent`,
+  `scheme=CORE`) with today's signature date,
+- validates it (state → *valid*).
+
+Partners with no bank account, or that already have a draft/valid mandate,
+are skipped. A notification reports created / skipped counts.
+
+> **Legal note:** only create mandates for members who have actually
+> authorised the direct debit. Adjust the signature date in
+> `data/server_action.xml` if you need the real authorisation date.
+
+## Requirements
+
+Depends on `account_banking_sepa_direct_debit` (OCA `bank-payment`), which
+pulls in `account_banking_mandate`, `account_payment_order` and
+`account_payment_mode`.
