Written vs Verbal Approvals: Why Your Garage Needs a Paper Trail

"I never authorised that work." Five words that cost UK garages thousands of pounds every year.

Verbal approvals are the industry standard, and they're a ticking time bomb. A customer agrees to extra work over the phone, you do the work, and when the bill arrives, they dispute it. Without written evidence, who wins that argument?

The problem with verbal approvals

Verbal approvals leave no trace. There's no record of exactly what was agreed, when it was agreed, or who agreed to it. In a dispute, it becomes your word against the customer's.

Even with the best intentions on both sides, misunderstandings happen. A customer might think they approved a diagnostic check, not a full repair. The advisor might have explained it perfectly, but without documentation, there's no way to prove it.

What a written approval looks like

A proper written approval system records who approved the work (verified customer identity), what exactly was approved (specific items with descriptions), how much it costs (itemised pricing), and when it was approved (timestamp). This creates an immutable record that protects both the garage and the customer.

The legal position

Under UK consumer law, garages need clear consent before carrying out work. While verbal consent is technically valid, proving it exists is almost impossible. Written approvals provide unambiguous evidence of informed consent.

The Motor Ombudsman and trading standards bodies consistently recommend documented approval processes. Garages with written trails see dramatically fewer complaints escalated to formal disputes.

Making it frictionless

The key to written approvals working in practice is making them effortless. If a customer has to print, sign, and return a PDF, adoption will be terrible.

The best approach is a mobile-friendly approval card that shows the work needed, the cost, and a single "Approve" button. The customer taps once, and the approval is recorded with their identity and a timestamp. Done in 10 seconds.

The bottom line

Written approvals cost nothing to implement but can save thousands in disputed invoices. More importantly, they build trust. When customers can see exactly what they approved and when, disputes become almost non-existent.

Stop relying on memory. Start documenting everything.
