Quote the Whole Shortage List, Hard Lines Included

A buyer at an OEM sends over a shortage list on a Tuesday morning. Sixty lines pulled from the BOM for a build that starts in three weeks. Some are allocated, some have long lead times, and a handful are parts the manufacturer stopped making a while ago.

Your desk checks the shelf and finds nine. Those get a quote within the hour, which feels like good service. The other fifty-one lines get “no stock” or no reply at all.

The buyer still has fifty-one problems. Somebody else is going to solve them, and whoever answers the most of that list, the hard lines especially, is the one the buyer calls next time.

I should say plainly that I’m not an engineer and I’ve never quoted a BOM. I spent almost 18 years running Infographic World, a digital agency, and now I use AI to fix real problems inside businesses. What I pay attention to is where work stalls in an office. On a shortage list, it stalls on the lines that need reading and research, which is exactly where the value is.

Where the time goes on a shortage list

The easy lines are easy. The cost is all in the rest.

• Reading the list. Manufacturer part numbers mixed with the customer’s internal numbers, descriptions instead of numbers on some lines, quantity per board that has to be multiplied by the build.
• The stock check. Quick for exact matches on the shelf.
• The hard lines. Obsolete, allocated or long-lead parts. Answering these means finding a manufacturer’s cross reference or a form-fit-function alternate, and that means reading datasheets: package, pinout, voltage, temperature range, tolerance, qualification level. Easily an hour a line for someone who knows what to look for.
• Sourcing. Once there’s a candidate, finding stock of it at a trace grade the customer will accept.
• The answer. One response that tells the buyer, line by line, what you can do.

Most desks do the first two and stop, because the third takes the time of the most skilled person in the building. So the hardest lines, the ones the buyer is most worried about, get the least attention.

What the AI-assisted version looks like

It reads the whole list

The first step takes the list in whatever form it came: a spreadsheet, a PDF export, a pasted table in an email. It pulls out the part numbers, descriptions, quantities and any notes, and matches internal numbers to manufacturer numbers where the customer’s history makes that clear. Uncertain matches get flagged for a person.

It finds stock and recent buys

Every line is checked against your shelf and your recent buying history, with trace grade and date code shown. The easy lines are done in minutes instead of an hour.

It suggests alternates, with the reasons laid out

For each hard line, the system looks for manufacturer cross references and parts with matching form, fit and function, and lays the candidates side by side with the original: package, pinout, electrical ratings, temperature range, qualification. Every difference is called out, not smoothed over. A slightly narrower temperature range or a different lead finish is stated right there on the line.

An engineer or your most technical salesperson reviews the suggestions before anything goes to the customer. Weak ones get dropped. The ones that survive go out clearly labeled as suggestions that need the customer’s engineering approval.

It assembles one complete answer

The buyer gets a single response covering every line: in stock, alternate suggested for engineering review, sourceable with a stated lead time, or no answer, with the reason. That’s a very different reply from nine prices and silence.

Run the numbers

The formula in words: shortage lines received per month, times the share you quote, times your win rate on quoted lines, times average margin per won line. Then compare today’s share quoted with what it could be.

Say, for the sake of the math, you get 20 shortage lists a month at 60 lines each, so 1,200 lines. Today you quote 20 percent of them, or 240 lines. You win 20 percent of what you quote, and a won line brings $150 of margin. That’s 48 won lines and $7,200 a month. All of these are made-up numbers.

Now say, also made up, that reading every line and suggesting alternates lets you quote half the lines, 600 in all. The extra 360 lines are harder, and some alternates won’t get approved, so give them a lower win rate of 10 percent. That’s 36 more won lines and $5,400 more margin a month, on lists that were already in your inbox.

To run it on your own numbers, pull three:

1. Shortage lists received per month and the average line count. The last 20 lists will do.
2. The share of lines you actually quoted on those lists.
3. Average margin per won line.

If your desk tracks it, a fourth number helps: how often a customer placed most of a list with one supplier. That tells you what a complete answer is worth beyond the individual lines.

Picture a Monday, before and after

This scene is made up.

Before. A 60-line shortage list came in Friday afternoon. Monday morning a salesperson checks the shelf, quotes the nine lines in stock, and replies “no stock” on the rest. The engineer who could have found alternates for a dozen of them never sees the list. By Wednesday the buyer has placed most of it with a distributor who answered every line.

After. The same list was read over the weekend. Monday morning the salesperson opens one draft answer: nine lines in stock, fourteen sourceable with stated lead times, eleven with suggested alternates and the differences listed beside each one. The engineer spends forty minutes on the alternates, drops three, and approves the rest to go out as suggestions. The buyer gets a reply covering most of the list before lunch, with every alternate marked for their own engineering review.

What has to be in place first

• A stock list with trace grade and date code per line, current enough to quote from.
• Recent buy history by part, with the sources you trust.
• The cross reference and alternate knowledge you already have, written down. If it lives in one engineer’s head, getting it on paper is worth doing for its own sake.
• Access to manufacturer datasheets for the parts you deal in most.
• A named person who reviews every suggested alternate before it leaves the building.
• A clear picture of how each customer approves alternates. Some need a formal deviation, some an email from the engineer, some won’t take alternates at all.

Guardrails worth keeping

• Alternates are suggestions. The customer’s engineering approves, in writing, before anything ships against one.
• Every difference is stated. If the alternate differs from the original in any rating, package detail or qualification, the quote says so on that line.
• Qualified parts stay qualified. A part built to a military or space specification doesn’t get a commercial alternate suggested unless the customer asks for one. What a 5962 Number Tells a Buyer in Ten Seconds covers why those markings matter.
• Trace grade goes on every line. An alternate from an untraceable source is a different offer from one with full trace, and the price should reflect that, as Trace Grade Is a Price, Not a Paperwork Problem explains.
• The BOM stays confidential. It can reveal a customer’s design. Business-grade tools only, with access limited.

How you’ll know it’s working

• Share of lines quoted per shortage list, month over month.
• Hours from list received to complete answer sent.
• Alternates suggested, and the share the customer’s engineers approve.
• Won lines per list.
• Lists where the customer placed most of the lines with you.

Where I’d start

Pull the last ten shortage lists and mark every line you didn’t quote. Run alternate suggestions on those lines only, and have your engineer grade each suggestion as usable, close or wrong. If more than a handful are usable, you have your answer on whether the hard lines are worth quoting.

If shortage lists cross your desk every week, the free week on the Hunt page counts the requests you already get by part over 90 days, which shows how often those hard lines come back around.
