A repair shop can't print a price. Model the floor and the scope instead.
The last time you had your brakes done, the number at the top of the invoice was not the number you had been told. It was higher, and it was higher for a reason that was entirely legitimate: the rotors measured under spec, or a bolt was seized, or the pads that came off were not the pads the price list assumed. Every shop owner knows this story. It is why so many independent garages have no price…
When you last had your brakes serviced, the invoice did not feature the figure you were initially quoted. It was higher, and this increase was justified by factors such as rotors that were under specification or seized bolts and seized pads. Every independent garage acknowledges this scenario, which is why many lack a price list on their walls.
A fixed price sheet is seen as a binding contract, but it's impractical as the job's scope cannot be determined beforehand. Publishing no price is not a neutral decision; it shifts the decision-making process to a telephone conversation where the shop competes against others based on a figure that lacks context. The ideal solution lies in presenting the floor plan along with the scope, in a manner that remains consistent despite external variables. This problem is multifaceted, encompassing data modeling, typography, and QR code geometry.
The simplest service price structure requires two fields: the job description and the cost per axle. Some variables, like the vehicle condition and parts tier, are unknown when pricing but become clear upon completion. This structure prevents the creation of inaccurate price lists, which is far worse than having no list at all. The most fundamental structure that endures real-world conditions includes a floor plan and two arrays: one listing the job details and another detailing the services included or excluded.
It's crucial to include the floor measurement as a unit of cost to avoid discrepancies in pricing. The exclusion field defines what will be charged, making the floor plan defensible by outlining potential charges. Neglecting to include these details can lead to unforeseen expenses and disputes.
However, listing every possible charge on an invoice is impractical. A practical approach is to include these charges as a policy block on every ticket. This approach converts potential surprises into policies that customers have agreed to. Additional charges such as shop supplies, disposal of old tires, TPMS services, fixing broken hardware, and diagnostic fees should be included in this block.
This ensures transparency and policy clarity for customers. The invoice should also clearly indicate that all prices exclude tax. This comprehensive approach to pricing is applicable to various trades such as plumbing, dentistry, auto body, and veterinary services. It sets a high-value user interface (UI) component that is often absent in existing systems.
The QR code, which encodes this information, should be sized according to the viewing distance, following a 1:10 code-width-per-meter rule. This ensures the QR code is legible from various distances, enhancing accessibility and usability for all customers.
