Complete Customer & Supplier Tracking - Implementation Summary

✅ What Has Been Implemented

Phase 1: Bill-to-Customer Linking ✅

Problem: Bills may not always have master_order_customer_id set correctly.

Solution Implemented:

1. Auto-set customer in create() method (account_move.py):

   • When a bill is created with master_order_id, automatically sets master_order_customer_id
   • Ensures customer is always set when bill is created

2. Auto-update customer in write() method (account_move.py):

   • When master_order_id changes, automatically updates master_order_customer_id
   • When master_order_id is removed, clears master_order_customer_id

3. Enhanced _link_master_order() method (account_move.py):

   • Now always sets customer when linking to MO
   • Ensures customer is never missing when MO is linked

4. Validation constraint (account_move.py):

   • _check_customer_consistency() ensures customer matches MO customer
   • Prevents data inconsistencies

5. Auto-create supplier debt (account_move.py):

   • _create_supplier_debt_record() creates supplier debt when bill is posted
   • Ensures supplier debts are tracked per customer automatically

Phase 2: Supplier Payment Tracking ✅

Problem: Supplier payments may not be properly linked to customers.

Solution Implemented:

1. Enhanced payment-to-customer linking (document_links.py):

   • Method 1: From Master Order (existing)
   • Method 2: From master_order_customer_id on bills (NEW)
   • Method 3: From reconciled bills directly (NEW)
   • Ensures customer is always found when payment is made

2. Supplier payment transaction creation (document_links.py):

   • Creates paid_out transaction for supplier payments
   • Links transaction to customer cash flow
   • Sets counterparty_id to supplier

3. Auto-update supplier debt (document_links.py):

   • Calls cashflow._update_supplier_debt() when payment is made
   • Refreshes supplier debt totals automatically

Phase 3: Supplier Debt Tracking ✅

Problem: Supplier debts may not reflect all bills correctly.

Solution Implemented:

1. Auto-create supplier debt on bill post (account_move.py):

   • _create_supplier_debt_record() called when bill is posted
   • Creates vera.client.supplier record if doesn't exist
   • Links supplier debt to customer cash flow

2. Update supplier debt method (vera_client_cashflow.py):

   • _update_supplier_debt() refreshes supplier debt totals
   • Called when payments are made
   • Ensures supplier debts are always up-to-date

3. Supplier debt computation (vera_client_supplier.py):

   • Uses master_order_customer_id to find bills (more reliable)
   • Computes totals from bills and payments correctly
   • Shows accurate outstanding amounts per customer

Phase 4: Migration & Repair Tools ✅

Implementation:

1. Migration script (account_move_migration.py):

   • repair_all_bill_customers() - Fixes all bills with missing customer links
   • sync_all_payments_to_cashflow() - Syncs existing payments to cash flow

2. Repair wizard (repair_customer_links_wizard.py):

   • UI for running repair operations
   • Options to repair bills, create supplier debts, sync payments
   • Shows summary of fixes
