A customer reorders a part you made eighteen months ago. You send an RFQ to the same three suppliers. A quote comes back at a number that feels high — but you can't say how high, because you can't find what it cost last time.
So you accept it, or you push back on instinct.
The history exists, it's just not reachable
This isn't a data problem. You have every one of those quotes. They're in an email thread, a PDF in a folder named after the customer, or a row in a spreadsheet that got archived when the tabs got slow.
The information exists and can't be retrieved in the ninety seconds you have while deciding — which, in practice, is the same as not having it.
What the history is actually worth
A negotiating position that isn't a feeling. "That's up about 14% on what you quoted in March last year — has material moved that much?" is a question a supplier can answer. "That seems high" is one they can only disagree with.
Knowing whether it's the supplier or the market. If all three came back 12% up, that's material and everyone's dealing with it. If one came back 30% up and the others 10%, that's about that supplier — capacity, priorities, or how they see your account.
Not re-running dead ends. Last time one supplier no-quoted and another quoted fourteen weeks. Sending them the same RFQ spends your time and theirs rediscovering it.
Catching the drift. A supplier who creeps 4% above the others every year is invisible job-to-job and obvious across five.
The version that costs nothing
You don't need a system to start. You need requoted parts to be findable by part, not by date or customer:
Name things by part number, not "quote for Johnson". Any folder, any filing scheme — as long as the part number is in the name, next year's you can find it.
Keep the quotes you didn't take. The losing quote is what tells you whether today's number is reasonable.
Write down why you awarded it. One line. "Cheapest and the only one who'd hold the date" is worth more in a year than the numbers alone.
What changes when it's automatic
When RFQs live somewhere structured, this stops being filing discipline and becomes a property of the system: open the part, see every time it's been quoted, by whom, at what, and what happened.
Two things follow that are hard to get any other way.
You can see a supplier's pricing pattern across all their quotes, not just this part — who's consistent, who moves with material, who moves with how busy they are.
And repeat RFQs stop being a fresh start. You're not asking "what does this cost?" but "is this still the right number?" — a shorter conversation, and one that tends to produce a better answer.
The thing worth noticing
Most shops treat each RFQ as an event: it opens, it closes, it's done. But the same parts come back, and the same suppliers quote them.
Every quote you've received is a data point about a supplier you're still using. Thrown away, you start from zero each time. Kept and findable, the fifth quote for a part is a far better conversation than the first — and it costs nothing except not deleting anything.
