A wheel-speed sensor that shipped same-day in 2019 now routinely sits on a 6 to 9 day national backorder when the local warehouse runs dry. That is not a pandemic hangover story anymore. Parts delays have settled in as a permanent feature of running an independent shop, driven by tighter aftermarket inventory, more model-specific electronics, and distributors carrying leaner stock than they used to.
Here is why it matters for your bays: a delayed part does not just push out one job. It ties up a lift, freezes an approved ticket, and turns one annoyed customer into three when the cars behind that job start backing up too. The shops staying profitable through this are not the ones with a magic supplier. They are the ones who built a process around the delay instead of getting surprised by it every week.
Below is a checklist organized by where you are in the job. Work through it stage by stage.
Stage 1: At the Estimate
Most parts problems are decided before you ever order anything. The estimate is where you set expectations, and it is where you catch the long-lead items early.
- Check availability before you quote the completion time. Do not promise “done by Thursday” until you have confirmed the key part is in a local warehouse. On a 2015 European model, a control module can be a 4 to 7 day wait, and that changes the whole conversation.
- Flag electronics and dealer-only parts. Sensors, modules, and anything with a part number that only the OEM stocks are your highest-risk items. Mark them at estimate time.
- Quote a realistic window, not a hopeful one. A customer told “Friday” who gets the car Tuesday is thrilled. The reverse burns trust.
- Note a backup supplier on the estimate itself. If your first-call jobber is out, know who your second and third calls are before you need them.
Getting this right up front is the difference between a smooth job and a comeback conversation. If you are still building estimates on paper or a whiteboard, this is exactly where things slip through. Our breakdown of what a paper system actually costs you every month walks through where those gaps show up.
Stage 2: At Ordering
Once the job is approved, ordering is where speed and accuracy pay off. A wrong part on a slow supply chain can cost you a full week.
- Order approved parts within the hour, not end of day. On backordered items, being an hour earlier in the queue can move you an entire shipping cycle ahead.
- Confirm the exact fitment before you click. A returned wrong-fitment part on a 10-day backorder means you start the clock over. Verify VIN-level fitment.
- Batch your daily orders to one or two supplier runs. Fewer, cleaner orders reduce mistakes and let you negotiate delivery timing.
- Log every backorder with an expected date. “It’s coming” is not a date. Get the ETA in writing and put it on the ticket.
A shop doing 25 tickets a week that shaves even one day off two backordered jobs frees up a lift sooner and gets paid sooner. Over a year, that is real throughput. If you want to see how that time adds up in dollars, our shop software ROI math lays it out.
Stage 3: While the Car Waits
This is where most shops lose customers. The car is sitting, the part is late, and nobody told the owner. Silence during a delay is how a repairable situation turns into a one-star review.
- Update the customer the moment the ETA slips. A quick text saying “Your part is now expected Wednesday, we’ll have you back on the road Thursday” prevents the angry noon phone call.
- Offer a status the customer can check themselves. People do not want to call. They want to glance at their phone. Giving them a link to the job status cuts your inbound calls sharply. Our guide to texting software for shops covers how shops handle this without adding staff.
- Keep the bay productive. If a job is stalled on a part, move the car off the lift and pull the next approved job in. A frozen lift on a 5-day wait is 5 lost days of capacity.
- Track waiting-on-parts jobs in one place. These are the tickets that get forgotten. They need to be visible, not buried in a stack of paper repair orders.
Stage 4: At Delivery and After
The part shows up, the job wraps, and you think you are done. Not quite. The follow-through here protects your margin and your reputation.
- Inspect the part on arrival. A cracked housing or wrong revision level caught at the counter beats one caught at final assembly.
- Bill the delay honestly. If a rush shipping fee was needed and the customer approved it, itemize it. Do not eat freight silently and wonder where your margin went.
- Log the supplier’s performance. Which vendors hit their ETAs and which slipped? After 90 days you will know exactly who to call first.
- Close the loop with the customer. A short note thanking them for their patience during the delay turns a frustrating wait into a loyalty moment.
The shops that treat parts delays as a workflow problem instead of a supplier problem are the ones keeping bays full and customers calm. The delay is not going away. Your process for handling it is what customers actually remember.

Frequently Asked Questions
Isn’t this just a supplier problem I can fix by switching jobbers? A better supplier helps, but no single distributor stocks every part every time. The shops that stay smooth have two or three backup sources and a process for catching long-lead items at the estimate. Switching vendors alone does not fix a workflow that assumes every part ships same-day.
I run a 3-bay shop. Do I really need a system to track waiting-on-parts jobs? The smaller the shop, the more one stalled lift hurts. At 3 bays, a single frozen ticket is a third of your capacity. Whether it is a dedicated board or a whole-shop view, you need those waiting jobs visible so they get pulled forward the day the part lands, not three days later.
Won’t texting customers about delays just invite more complaints? The opposite. Customers get angry about silence, not honesty. A quick heads-up when an ETA slips reduces inbound calls and defuses frustration before it becomes a review. Shops that update proactively during delays report fewer angry pickups, not more.
