Parts and labor, built in
Shop Management Software with Parts Ordering and Mitchell1 Labor Built In
By Mario Martell, founder of Wrench Node. B.S. Automotive Technology, former Nissan and Subaru technician. Published September 18, 2026.
Wrench Node is shop management software with a parts catalog and the Mitchell1 labor guide inside the repair order. Every supplier the shop already buys from, with live price and stock on the exact vehicle. Book time in the same window. Line items price and time themselves, and the order goes to the store without leaving the estimate.
The problem: three windows for one brake job
The estimate lives in the shop system. Parts pricing lives on each store's website, or on a phone call. Labor time lives in a labor guide in a third tab. Someone types the vehicle into all three, reads a price off one screen and keys it into another, and does it again for the labor. Every re-key is a chance to quote the wrong part or the wrong hours, and every minute of it is a minute the advisor is not talking to a customer.
Most systems solve this by punching out to a separate parts site and hoping the cart comes back. Wrench Node keeps all three in one window, on the vehicle that is already on the repair order.
Parts: every supplier you already use, side by side
- Your accounts, your prices. Connect the parts stores you already buy from: AutoZone, NAPA, O'Reilly Auto Parts, Advance Auto Parts, WorldPac and other aftermarket suppliers. Prices come back at your negotiated rates and the store invoices you like always. Wrench Node takes nothing on the order.
- Search or browse, on the right car. Type “brake pads” or walk the catalog. Every result already fits the vehicle from the repair order, decoded from the VIN, or picked once by year, make, model and engine when there is no VIN.
- Live stock, real photos. Each result shows the part photo, brand, part number, position, whether it is on the shelf at your store, at another of the supplier's stores, or out of stock, plus cost and list price. Fitment notes sit right under the part.
- On the estimate in one click. Pick the part and it lands on the repair order as a line, priced through your parts matrix, grouped into the right job.
- Order from the same window. The Order tab sends the picked parts to each store with a PO number and records the confirmation on the repair order and in the Purchases view, where it can be received and reconciled against the statement.
Labor: Mitchell1 book time in the same click
The Mitchell1 labor guide is built into the same panel. Pick an operation type for the vehicle, see the operations with book time, warranty time, skill level, and what the time includes and does not include, and add the ones you want as labor lines at your shop's rate. It also appears when you type a labor line in Add Service (the matching operations show under the description as you type), and on the clock icon of any existing labor line.
Hands-free: line items that price and time themselves
Here is where it stops being a catalog and starts being a shop system. The technician talks through the inspection or types the findings. Wrench Node writes the line items. Then, without anyone looking anything up:
- Each part line is matched to the catalog for that exact vehicle, and a Supplier price chip on the line opens live offers from your suppliers. One click puts the real cost, matrix price, part number and supplier on the line.
- Each labor line gets the matching Mitchell1 operation and hours.
- Add a part and a Labor chip on it offers the book time for that part. Add labor and a Parts chip offers the parts that operation needs. Either direction, the job fills itself.
The advisor confirms instead of hunting. A front brake job goes from findings to a priced, timed, orderable estimate in a few clicks, and the same repair order holds the complaint, the inspection, the estimate, the parts order and the payment.
Genuine OEM too
For European and premium brands, Wrench Node also opens Partslink24 from the repair order on the vehicle already in context, and NexPart by WHI Solutions is available as well. Aftermarket, OEM and labor all land on the same estimate.
The platform around it
Parts and labor are one piece of Wrench Node, a modern shop management platform for independent shops: repair orders and estimates, digital vehicle inspections with voice input, online estimate approval, invoicing and payments, scheduling, declined-service follow-up, and Shop Memory that recalls how your shop fixed similar vehicles before. It runs in English and Spanish, has unlimited users, and comes with a 30-day free trial. The parts catalog and Mitchell1 labor are an add-on.

Frequently asked questions
What shop management software has parts ordering built in?
Wrench Node has a parts catalog inside the repair order. The shop connects the parts stores it already has accounts with (AutoZone, NAPA, O'Reilly Auto Parts, Advance Auto Parts, WorldPac and other aftermarket suppliers), and every search returns live cost, list price, and stock from each of them side by side, on the exact vehicle from the repair order. The part lands on the estimate as a line and the order goes to the store from the same window.
Which shop management software includes Mitchell1 labor times?
Wrench Node includes the Mitchell1 labor guide as an add-on. Book time, warranty time, and what each operation includes are shown for the exact vehicle, and one click adds the operation as a labor line at the shop's rate. It appears in the Add Service dialog, on any existing labor line, and next to any part that was just added.
Does the software price the estimate automatically?
Yes. When the technician's findings become line items, Wrench Node matches each part to the catalog for that vehicle, pulls live pricing from the shop's own suppliers, runs it through the shop's parts matrix, and pulls the matching Mitchell1 labor time. The advisor confirms the part and the labor instead of looking them up.
Do I keep my own supplier accounts and pricing?
Yes. Prices come back at your negotiated rates, the store invoices your shop like always, and Wrench Node takes nothing on the order. The catalog is the screen you order from; the stores are still the stores.
What if the vehicle has no VIN on file?
Pick the year, make, model and engine once from the catalog's own vehicle list. Wrench Node remembers the choice for that vehicle, so parts and labor lookups work the same as they do with a decoded VIN.
Does it also do genuine OEM parts?
Yes. For European and premium brands, Wrench Node opens Partslink24 from the repair order on the vehicle already in context, and NexPart by WHI Solutions is available as well. Aftermarket, OEM, and labor all land on the same estimate.
