How Should a Parts Manager Handle Following Up on a Delayed Parts ETA?

When a parts ETA slips, your parts manager should notify affected technicians and service advisors within an hour, confirm the new arrival date with the supplier, and update the customer and service timeline accordingly. Document the delay reason, flag it in your DMS, and use it as data to adjust future ordering patterns and supplier performance reviews.

Why Parts Delays Happen and Why You Need to Track Them

Parts delays are not random. They follow patterns. A distributor might be out of stock on a common item. A manufacturer might have a backorder queue. A freight carrier might miss a delivery window. Your supplier might have marked the ETA conservatively to look good when it ships early.

The worst thing a parts manager can do is treat each delay as a surprise. Instead, treat delays as operational data. Track them. Count them. Know which suppliers miss their dates most often, and which parts categories have the longest lead times.

Here's the hard truth: stores that don't track this tend to blame technicians for "not ordering early enough" or blame service advisors for "overselling what we can turn." But the real bottleneck is often the supply chain itself. Until you measure it, you can't fix it.

Keep a simple log. When an ETA gets pushed, write down the part, the original date, the revised date, the reason (if the supplier tells you), and the supplier name. After three months, you'll see which suppliers are reliable and which ones consistently under-deliver on timing. That data is gold for your negotiations and your reconditioning roadmap.

Step 1: Notify Your Team Immediately When You Hear About the Delay

The moment a distributor tells you a part won't arrive on the promised date, you have a window—maybe 30 minutes to an hour—to tell the people who depend on that part.

Your primary audience is the technician or service advisor tied to that RO. They need to know right away because they're planning their day around that part. If they don't hear from you, they'll waste time waiting, or they'll over-commit to other work and then scramble when the part finally shows up.

Send a message through your DMS team chat, text, or email,whatever your dealership uses. Be direct and factual:

• The part name and part number
• The RO it's tied to
• The original promised arrival date
• The new expected arrival date
• Why it's delayed (if you know)
• What happens next (e.g., "I'm calling the customer at 2pm to let them know")

Don't bury the news. Don't wait until end of shift. Technicians and service advisors need time to adjust their workflow. A 24-hour delay on a timing belt for a 2017 Pilot at 105,000 miles changes the whole day's plan.

Step 2: Confirm the New ETA Directly with Your Supplier

When a distributor tells you a part is delayed, ask a follow-up question: "What is the actual expected delivery date?" Not "hopefully" or "we think." Actual.

This is where parts managers often get sloppy. They accept the first answer and pass it along. But suppliers sometimes hedge. They say "early next week" when they mean "Tuesday or Wednesday, we're not sure." That vagueness cascades down to your service team and your customer.

Push for specifics:

1. Get a new date and time window if possible (e.g., "Tuesday by 11am")
2. Ask if the part is actually in stock at the warehouse or still being processed
3. Find out the shipping method (ground, expedited, local pickup)
4. Get a direct contact at the supplier in case the date slips again

If the supplier can't give you a firm date, ask when they'll have one. Don't accept "we'll call you." Tell them you need an answer by a specific time. Parts managers who are most effective treat suppliers like they're part of their team,which they are.

Note: You might run into a situation where a supplier genuinely doesn't know when a part will arrive because it's on backorder from the manufacturer. In that case, ask for weekly check-ins instead of a single ETA. That's different from a "we'll let you know" brush-off, and it keeps the communication channel open.

Step 3: Update the Service Timeline and Customer Expectations

Once you've confirmed the new ETA with the supplier, your service advisor needs to contact the customer. Don't wait. The customer should hear from your dealership first, not from a technician who calls wondering where their car is.

The service advisor should explain:

• The part is delayed but has arrived at the supplier (or will arrive by [date])
• The revised pickup or delivery date for the vehicle
• Whether there are any additional costs or changes to the estimate
• An offer: does the customer want a loaner, or are they okay waiting?

Most customers get frustrated not because parts are delayed,that happens,but because they hear about it late and no one told them what to do. A parts manager who communicates delays proactively, with a clear new timeline, usually keeps the customer calm and the CSI score intact.

Update your DMS so the service timeline is accurate. If the part was supposed to arrive Tuesday and now it's Thursday, move the customer's expected delivery to Thursday (or Friday if you're being conservative). Don't leave it at Tuesday. That creates a second disappointment when the car isn't ready.

Step 4: Document the Delay and Flag It for Review

This is the step most parts managers skip. And it's the step that separates dealers who fix supply problems from dealers who just complain about them.

In your DMS or parts-tracking system, create a note that records:

• The supplier name
• The part number and description
• The original promised date
• The actual delivery date (once it arrives)
• The reason for the delay (backorder, out of stock, carrier delay, etc.)
• The impact (RO held up, customer unhappy, loaner cost, etc.)

Pull this data quarterly. Which suppliers are hitting their dates 90% of the time? Which ones are 70%? Which parts categories are chronically delayed (OEM engines, transmissions, body panels, etc.)? Are certain manufacturers worse than others?

Use this for your supplier performance review. A supplier that misses 30% of their ETAs should be on a performance plan. A distributor that hits 95% earns more of your business. This is basic vendor management, but most dealerships don't do it because they don't track it.

This kind of workflow is exactly what Dealer1 Solutions was built to handle,flagging delays, routing notifications to the right team members, and capturing the data for future analysis.

Step 5: Adjust Your Ordering Practices Based on Supplier Performance

After you've tracked delays for a few months, you'll see patterns. Use those patterns to change how you order.

For example, if your main OEM distributor consistently delivers transmission parts 3–5 days later than promised, you should start ordering them earlier. Not because you're bad at planning, but because that's the real lead time for that supplier. Your original estimate was based on their promised date, not their actual performance.

Some dealers shift volume to faster suppliers. Some add a buffer to every critical part order. Some negotiate with their distributor about realistic dates. All of these require data.

You might also notice that certain parts are almost always delayed because they're rarely in stock. A typical $3,400 timing belt job on a 2017 Pilot at 105,000 miles might mean a 2–3 day wait for a timing belt from one distributor but only 1 day from another. Once you know that, you can adjust your sourcing or build it into your T.O. conversations with customers.

Common Mistakes Parts Managers Make with Delayed ETAs

Don't assume the technician knows. Just because a part was ordered doesn't mean the tech is tracking the arrival date. Tell them. Twice.

Don't assume the customer is okay with a longer wait. Some customers have tight schedules. A 24-hour delay might destroy their week. Call them early, not the day before pickup.

Don't blame the service advisor for ordering late. The service advisor's job is to sell and schedule. The parts manager's job is to know lead times. If a part typically takes 4 days and a customer wants a 2-day turn, that's a conversation between you and the advisor,not something to flag after the fact.

Don't let a supplier give you a soft answer twice. If they miss a date and can't explain why, ask them to set a realistic window next time. If they miss twice, consider switching distributors for that part.

How to Prevent Delays Before They Happen

The best parts managers don't just react to delays. They prevent them.

Order critical parts earlier than you think you need them. Build a 1–2 day buffer into your order timing, especially for OEM parts or items that come from single sources.

When a service advisor writes an estimate that requires an ordered part, confirm availability before you commit to the customer. Check stock at your main distributors. Ask the supplier how fast they can get it. Then add a day for safety.

Maintain relationships with backup suppliers. If your primary distributor is out, you need a second source that can ship overnight or offer local pickup.

Track fast movers. Which parts do you order most often? Stock some of them. A high-turnover part that typically has a 3-day ETA might be worth carrying in inventory to cut that to 30 minutes.

Frequently asked questions

Should I always call the customer when a parts ETA gets delayed?

Yes, if the delay affects the delivery date or pickup date the customer was promised. If a part is delayed by one day and the car was going to be ready Friday anyway, a quick text or email is fine. If the delay pushes the car back 2–3 days, call. Customers appreciate hearing from you directly before they start wondering where their car is.

How should I handle a supplier who consistently misses their ETAs?

Start by asking them why. Is it a freight problem, a warehouse issue, or lack of inventory? Give them one chance to explain and improve. Track their performance for the next 30 days. If they're still missing dates, reduce your order volume with them and shift it to a more reliable supplier. Don't stay loyal to a supplier who doesn't deliver.

What should I tell a technician whose part is delayed?

Be specific: the part name, the new arrival date, and what they should do in the meantime. If the delay is long, ask if they can work on something else or if the car should move to a holding lot. Don't leave them guessing. They need to know whether to plan around this RO or reassign their time.

Can I charge the customer for a loaner if a parts delay extends their repair?

That depends on your dealership's policy and whether the delay is your fault. If you ordered late or under-estimated the lead time, you shouldn't charge. If the supplier missed their date despite you ordering on time, many dealers cover the loaner cost as goodwill. Check with your service manager or BDC on your dealership's standard practice for this situation.

How do I know if I should start carrying a part in inventory instead of ordering it?

Pull your parts data for the last 12 months. If you've ordered the same part 15+ times, it has a consistent lead time of 3+ days, and your technicians have complained about waiting, it's probably worth stocking. Factor in the cost of inventory (carrying cost, potential obsolescence) versus the benefit of faster turns. Most dealerships stock high-velocity wear items like filters, belts, and common maintenance parts.

What's the best way to document parts delays in my DMS?

Create a standard note format: supplier name, part number, original date, revised date, reason, and impact. Tag it with a label like "Delayed ETA" so you can filter and report on it later. Review these notes monthly with your service manager to spot trends. If you're using a parts-tracking tool within your DMS, use the built-in ETA field and flag function. Data that's easy to find is data you'll actually use.
