A tire shop is two businesses sharing a building. One is a retailer selling a stocked product in dozens of sizes with real carrying cost. The other is a repair shop selling labor by the hour with a bay schedule and a comeback rate. General shop management software models the second competently and the first badly, which is why tire dealers so often end up with a spreadsheet of stock alongside it. This page is about what tire specific software has to do differently, and about the three numbers a tire business lives or dies by that a general system will not show you.
The size matrix is the hard part
A general shop system treats a tire as a part with a number. A tire business needs the size, the load and speed rating, the season, the brand tier and the quantity on hand, because a customer who needs two matching tires either can be served today or cannot. Software that cannot answer what do I have in this size, right now, is not doing the job, and every workaround involves somebody walking into the back to look, which is exactly the time the phone call was supposed to save.
Three numbers that decide a tire business
Stock turns, because tires are money sitting on a rack and a slow line is a loan you made to yourself. Attachment rate, meaning how often a tire sale carries an alignment, a valve, a balance or a repair, since that is where the margin actually lives. And comeback rate on fitting work, because a vibration complaint costs you a bay hour and a customer's confidence. A general shop system will show you revenue and hours and none of those three.
Disposal is a line, not a rounding error
Every tire that comes off has to go somewhere, and in most states that is a regulated waste stream with a per tire cost and paperwork behind it. Charging a disposal fee is normal and the mistake is treating it as trivial: at any real volume it is a meaningful number in both directions, and how it appears on the invoice is regulated in some states. Show it as its own line, set the amount from what your hauler actually charges, and review it when they change their price rather than a year later.
What the free tools do for a tire shop
The invoice builder on this site keeps parts at cost with your markup, the labor for fitting and balancing at your rate, shop supplies, and a disposal fee as its own input, so a tire ticket prices correctly without a general template fighting you. It computes in your browser and needs no account. What it does not do is track stock by size, which is a genuine limitation and worth saying plainly: if the size matrix is your problem, buy a system that models it.
Questions people ask about tire shop software
Do we need tire specific software or will a general shop system do?
If most of your revenue is fitting and service and tires are an occasional sale, a general system is fine. If you carry stock in dozens of sizes and the question what do I have drives your day, buy something that models the size matrix, because working around it never stops costing you.
How should the disposal fee be presented?
As its own labelled line at a rate you can justify from your hauler's invoice. Several states regulate how it can be described and what it may be called, so check your own rule before you print it on anything.
Is road hazard warranty worth selling?
It can be, and the thing to watch is the record rather than the maths: the claim comes back months later and you need to find the original sale, the tire, the date and the mileage. A warranty you cannot evidence is a promise you will end up honouring for free.
