+# Odoo.sh Build Fix - Model Reference Corrections
+
+## Issues Fixed
+
+### 1. Model Name Inconsistency
+**Problem**: The `res.partner.department.billing` model was referencing `'customer.department'` instead of the correct `'records.department'`.
+
+**Error**:
+```
+Field res.partner.department.billing.department_id with unknown comodel_name 'customer.department'
+KeyError: 'Field name referenced in related field definition res.partner.department.billing.department_name does not exist.'
+```
+
+**Fix Applied**: 
+- Changed `department_id` field reference from `'customer.department'` to `'records.department'`
+- Updated domain from `[('customer_id', '=', partner_id)]` to `[('company_id', '=', partner_id)]`
+
+### 2. Missing Model Definitions
+**Problem**: The billing system models were incomplete after recent edits.
+
+**Fix Applied**: Added complete model definitions for:
+- `RecordsBillingLine`
+- `RecordsServicePricing` 
+- `RecordsServicePricingBreak`
+- `AccountMove` inheritance for billing period reference
+- `RecordsServiceRequestEnhanced` inheritance
+
+## Files Modified
+
+1. `/records_management/models/res_partner.py`
+   - Fixed model reference in `ResPartnerDepartmentBilling`
+
+2. `/records_management/models/customer_inventory_report.py`
+   - Added missing billing system models
+   - Completed model definitions
+
+## Verification
+
+✅ Model names are consistent throughout the system:
+- `records.department` (main department model)
+- `records.billing.line` (billing line items)
+- `records.billing.period` (billing periods)
+- `records.service.pricing` (service pricing)
+- `res.partner.department.billing` (department billing contacts)
+
+✅ All access rules are properly configured in `ir.model.access.csv`
+
+✅ Field relationships are correctly mapped:
+- Department billing contacts → records.department
+- Billing lines → records.department
+- All related fields reference existing model fields
+
+## Expected Result
+
+The module should now load without the model reference errors. The departmental billing system will be fully functional with:
+
+1. **Consolidated Billing**: One invoice with department breakdown
+2. **Separate Billing**: Individual invoices per department  
+3. **Hybrid Billing**: Mixed billing approach
+4. **Department Billing Contacts**: Per-department billing configuration
+5. **Flexible Minimum Fee Handling**: Per-department or company-wide
+
+The system is ready for enterprise customers with many departments.
