Bookkeeping for Auto Body Shops in Calgary

Running an auto body shop in Calgary means juggling insurance claims, parts inventory, labour tracking, and customer payments all at once. The financial side of a collision repair business is more complex than most people realise, and getting your bookkeeping right is essential for profitability and compliance.

Bookkeeping Challenges for Auto Body Shops

• Insurance claim tracking. A large portion of your revenue comes through insurance companies, each with different payment timelines, supplement processes, and approval workflows. Tracking what is billed, approved, and paid requires careful accounts receivable management.
• Parts inventory and markup. You purchase parts from multiple suppliers, often with different markup structures for insurance versus customer-pay jobs. Tracking cost of goods sold accurately is critical for understanding your true margins.
• Labour rate management. Insurance companies negotiate labour rates that may differ from your posted door rate. Tracking labour revenue by rate type helps you understand profitability across different job categories.
• Sublet work. When you send work to specialty shops (glass, mechanical, upholstery), those sublet costs and revenues need proper tracking.
• Customer deductibles and co-pays. Collecting deductibles and tracking partial payments from customers alongside insurance proceeds adds complexity to your receivables.

Common Financial Mistakes Auto Body Shops Make

The most frequent mistake we see is failing to reconcile insurance receivables regularly. Insurance payments often arrive weeks after billing, sometimes with supplements or deductions that don't match the original invoice. Without monthly reconciliation, you can lose track of thousands in unpaid claims.

Another common issue is not separating material costs by job. When paint and supply costs are lumped together rather than allocated to specific repair orders, you lose visibility into per-job profitability.

GST Considerations for Auto Body Shops

Auto body shops must charge GST on all labour and parts, including insurance-paid work. The insurance company pays the GST as part of the claim, but you are responsible for collecting and remitting it correctly. Errors in GST calculation on insurance claims can lead to significant discrepancies at filing time.
