Free auto repair shop software: what's free, what it costs, and when to pay

Free auto repair shop software exists in three kinds: free plans from cloud vendors, free single-purpose tools (parts ordering, card payments, scheduling), and open-source programs you host yourself. Each lets a small or new shop write estimates and invoices at no monthly fee, but "free" usually costs something else: limited users, card-processing rates, your own time to run it, or trouble getting your data out later. Paid shop systems run from roughly $200 to $360 a month for the ones Tekmetric compares [1].

Below: what shop software has to do, the free options in each kind with their limits, a 30-minute test to run on a real job, and the signs that it's time to pay.

What shop software has to do

Before comparing names, list the jobs. A shop's day runs on these:

Customer and vehicle records. Who, what car, past work, so you stop asking the same questions.
Estimates and repair orders. Labor at your rate, parts at your markup, tax, shop fees, printed or sent to the customer.
Invoices and payment. Take a card, record cash, mark paid.
Parts lookup and ordering. Check price and stock across suppliers without phone calls.
Appointments. A calendar, and ideally online booking. Our mechanic booking website guide covers that side.
Reminders and follow-up. Text or email when a car is ready or due for service.
Reports. Sales, car count, average repair order, hours sold. Without them you can't tell if the shop is making money (see is owning an auto repair shop profitable?).

A free tool that does the first three well is already better than paper. The question is which of the rest you can live without.

Kind 1: free plans from shop software vendors

These are full or partial shop systems with a no-fee tier. Details change often; the limits below are what the sources say on 2026-11-05, so check each vendor's pricing page before relying on one.

Tool	What is free	Limit to check
Hibbitts Auto Pro	Estimates, invoices, customer records, point of sale, no subscription [1][2]	Tekmetric's review says one user [1]; likely no integrated approvals or deep reports [2]
Mechmate	A free Starter plan [2]	Upgrades needed for advanced features; check limits on users, inspections, reports and exports [2]
ShopBase	A free core tier, reportedly with unlimited users and work orders [2]	Described as funded by payment processing, so confirm the card rates [2]
Sayaaraa	A free option for booking and repair orders [2]	Public detail is thin on tax, labor rates, parts and integrations [2]

The pattern: a free plan is a way in. It gets you writing estimates today, and the vendor hopes you upgrade when you add a second tech or want texting and digital inspections.

Kind 2: free tools that do one job well

PartsTech. Parts lookup and ordering from multiple suppliers in one place. Tekmetric lists it as a free tier with limited functionality [1]. Many paid shop systems connect to it, so using it now doesn't lock you in.
Square. Tekmetric's list shows invoices, estimates, point of sale, scheduling and a basic website as free features [1]. Card processing is the usual way a payment company earns, so read its per-transaction rate.
SchedulingKit. A free auto repair plan for appointments only, with branding and automation behind paid tiers [2].
OBD Auto Doctor. A free tier for reading codes and some live data, with advanced functions behind Premium, and you need a compatible adapter [2]. This is a diagnostic aid, not shop management.

Two or three of these together (a free plan for estimates, PartsTech for parts, a scheduler) can run a one-person shop. The cost is that your records live in three places.

Kind 3: open-source you host yourself

Toolradar lists OpenAuto, Torqvoice and Dolibarr with a service-garage module as free to download and host [2]. There is no license fee, but you take on what a vendor normally does: setting it up, updating it, backing it up and keeping it secure. One of the listed sources warns about the security risks of free downloadable shop software. A customer list with names, phones and vehicles is data you're responsible for.

Self-hosting makes sense if you or someone you trust is comfortable running a server and keeping backups. If that isn't you, a vendor's free plan is safer than a free program you can't maintain.

What free really costs

Card-processing rates. If a "free" system earns through payments, compare its rate to your current one. On $20,000 a month in card sales, half a percent is $100 a month.
Your time. Typing in customers, setting up labor rates and tax, building a services list. Estimate an afternoon or two, whichever tool you pick.
Missing pieces. No texting, no inspections with photos, no accounting sync. Each is a manual job for you or the front desk.
Getting out. Ask whether you can export customers, vehicles and invoices as a spreadsheet. A tool that holds your history hostage is not free.
Support. When the system fails with a car on the lift, is there anyone to call?

A 30-minute test on a real job

Don't judge from a feature list. Take one real repair from last week (say a front brake job on a common car) and run it through each tool you're considering:

Add the customer and vehicle by VIN or plate. How many fields did it fill for you?
Build the estimate: labor at your rate, parts from your supplier, shop fee, tax. Does it match the number you actually charged?
Send the estimate to your own phone. Can the customer approve it without calling?
Convert it to an invoice, take a test payment, and print or email it.
Book the follow-up and set a reminder.
Export all of it. If you can't, stop here.

Time each step. If one job takes 15 minutes to enter, it will take that every day.

When free stops being enough

The usual signs: you add a second tech or a service advisor, you are re-typing the same job in two systems, customers ask to approve by text, you want photos in inspections, or you can't answer "what was our average repair order last month?" without a spreadsheet. AutoLeap's published monthly range for shop management software is $150–$400 [3], and Tekmetric's comparison has plans starting under $200 up to about $359 a month [1]. If better software adds one more approved job a week, it can pay for itself: at a $150 average repair order, a handful of extra jobs a month covers the fee, though you should work out your own numbers.

When you move, run the free tool and the paid one side by side for a week, and export the old data first.

Your first week with a free tool

Day 1: set the numbers. Enter your labor rate, parts markup matrix, tax rules and shop fee exactly as you charge today. Our how to charge for auto repair guide shows how to build them.
Day 2: build your canned jobs. Oil change, front brakes, rear brakes, battery, diagnostic. Saved jobs are where the time savings come from.
Days 3–5: run both. Write each real job in the new tool and your old method. Compare the totals.
Day 6: ask the front desk. The person who types the most should say what slows them down.
Day 7: export a backup and put a reminder in your calendar to repeat it monthly.

Software is not marketing

Shop software handles the car once it's in your bay. It does not bring cars in. That is your Google profile, your website and your reviews, which is the work in our guides to auto repair shop SEO and how to get more customers. Square's free basic website can work as a stopgap, but it's one page of a product built for payments. If you want a homepage built around your services, makes and phone number, email us your shop's name and we'll send a free preview.

Opening a shop on a tight budget

Software is one of the smaller lines in a startup budget, so it's one where free is realistic. Our cost to start an auto repair shop guide shows the monthly software line next to rent and payroll, and how to start a mechanic shop with no money shows what to keep free while you build. Start with a free plan, keep your exported data tidy, and upgrade on a real reason.

FAQ

Is there really free auto repair shop software?

Yes: free plans from vendors, free single-purpose tools, and open-source programs. Each has limits on users, features or support.

What is the best free software for a small mechanic shop?

It depends on your jobs. Hibbitts Auto Pro and Square are named as free in Tekmetric's list, and PartsTech is a free parts-ordering tier [1]. Test each on a real repair order.

Can I use QuickBooks or a spreadsheet instead?

For invoices and books, yes. They don't do estimates by vehicle, parts lookup or repair orders, so you'd do those by hand.

Is open-source shop software safe?

It can be if you keep it updated, backed up and secured. You carry that work yourself, so it suits owners comfortable with servers [2].

How much does paid shop software cost?

Tekmetric's comparison lists plans from under $200 to about $359 a month [1]; AutoLeap gives a $150–$400 range [3].

How do I switch later without losing my data?

Choose a tool that exports customers, vehicles and invoices before you commit, and export on a schedule.
