# POST /api/v1/advisory-firms/{firm_id}/templates/{template_id}/deploy

> Deploy a firm template to selected client businesses

- **Tag:** advisory-firm-templates
- **Operation ID:** `deploy_firm_template_api_v1_advisory_firms__firm_id__templates__template_id__deploy_post`

## Description

Bulk-applies the template to each business in ``business_ids``. COA templates use ``LedgerService.apply_coa``; bank-rule templates create new ``BankRule`` rows (duplicates by name are treated as skips so re-deploying is idempotent); review-checklist templates are recorded informationally.
