+## Deployment
+
+### Local Development
+```bash
+# Sync to odoonix
+~/src/bringout/0/scripts/odoonix_rsync.py account_payment_mode
+~/src/bringout/0/scripts/odoonix_rsync.py account_payment_partner
+~/src/bringout/0/scripts/odoonix_rsync.py account_payment_order
+~/src/bringout/0/scripts/odoonix_rsync.py account_payment_order_grouped_output
+```
+
+### Production
+```bash
+# Install in order:
+~/src/bringout/0/scripts/upgrade_production_nix_service.py \
+  --module account_payment_mode \
+  --module account_payment_partner \
+  --module account_payment_order \
+  --module account_payment_order_grouped_output \
+  --install
+```
+
+## Use Case
+
+**Problem:** Merge multiple payments to same supplier into one payment order
+
+**Solution:** Use `account_payment_order` to create payment orders that group multiple invoices
+
+**Workflow:**
+1. Go to: Accounting → Payments → Payment Orders
+2. Create new payment order
+3. Select move lines (invoices) from same supplier
+4. Confirm → Creates grouped payment
+5. Optional: Use grouped_output for consolidated accounting moves
+
+## Upstream Updates
+
+To update from OCA:
+```bash
+cd /tmp
+git clone -b 16.0 https://github.com/OCA/bank-payment.git
