Find out how much of your own customers’ work you’re not on.
Every builder you sell to pulls permits. We match your customer list to the permits filed in your area. Then we show you, builder by builder, the jobs your own records do not have you on, plus every builder near you with recent permits who is not on your list.
One file. No questions, no sales call, nothing to fill in. Your territory and which rep has which account are both read from the export your ERP already makes.
Four questions permits can answer and your CRM can't.
All of it free, all of it on the page the moment the check finishes.
Which of my own customers have jobs I am not on?
For every builder on your list: how many permits they pulled this year, how many of those jobs your records show you on, and what your share of the rest would be worth. This only looks at customers you already have, so a name you forgot to include makes the list shorter, never wrong.
Which builders near me are not my customers yet?
Every builder in your area with recent permits who is not on your list, ranked by your share of their work. This is your call list.
Where should I put a rep?
Your territory split into areas and ranked: where to push, where to hold, where a rep's time goes furthest. Ranked by the work you are not on, not by how busy the area is, so the busiest place does not automatically win.
How is each rep actually doing?
If your file names the rep on each job, you get a page for each rep: their accounts, their share of each builder's work, and a report you can forward with one goal for the quarter.
One file. Nothing to fill in.
Drop in your customer list
The export your ERP already makes. CSV or Excel. Column names and order do not matter. We work out which column is which.
We match it to permits
Each customer name is matched to the builder named on permits. Related company names count as one builder, so the six numbered companies one builder files under count as one customer. Your territory is worked out from where your customers build.
The report opens on this page
Not in your inbox, not after a call. Add an email afterwards only if you want a link back to it and a short note each week when something changes in your area.
It’s your customer list. Here’s exactly what happens to it.
You should not have to take a stranger’s word for this. None of what follows is a promise. It is what the code does.
Your file is deleted, not stored
We read the customer names out of it and delete the file in the same step. What we keep is the list of names: not your spreadsheet, not your invoice values, not your contacts.
Nobody at BuildMapper browses it
Your report is locked to you in our database, the same way every paying customer's is. It is never shown to another company, never mixed into a shared pool of data, and never sold.
Only 12 rows are used to read your column headings
To work out which column holds the customer name, the first 12 rows go to Anthropic, the AI company we use, under business terms that forbid training on them. It only ever answers "which column is which". Every value in your report is copied from your file by our own server, and the rest of the file never leaves it.
We only need one column
The customer name. A job address column makes it far more useful, and a rep column gives you a page per rep. But you can delete every other column before you send it (price, margin, contact, volume) and the check still runs.
Not ready to upload your own? Try it on ours.
A made-up supplier’s customer list, built from real building permits. Download one, run it through the check above, and you will see every screen before you decide whether to send your own file.
The ones managers actually ask.
Is it really free? What's the catch?
Yes, and there is no catch. The report, the map, the list of builders not on your list, the page per rep and the weekly note all cost nothing, and there is no time limit. We make money when a supplier wants the rest of BuildMapper: the full permit database, contacts, pipeline, alerts. This check shows you whether our data is any good for your area. That is the only honest way to sell it.
Can you tell me who my competitors supplied?
No, and anyone who says they can is guessing. A building permit names who built a job, never who supplied it. So when this says you are not on a job, it means your own records do not show you on it, not that you lost it. The report keeps that difference everywhere.
What if my file is messy?
It will be, and that is fine. We work out the column names ourselves, so send the export exactly as it comes out. Any customer we could not match to a builder is listed back to you, not quietly dropped.
Do I have to give you an email?
Not to see the report. It opens on the page. An email only gets you a way back to it: a sign-in link, and a short note each week when a builder in your area does something worth knowing. No address, no email, ever.
How current is the permit data?
New permits land every Monday, and the report covers the last 12 months. It tells you how many permits it read and over what dates, so you can judge for yourself how well we cover your area rather than take our word for it.
How accurate are the dollar figures?
A permit records what a project costs to build: the whole house. You only sell part of it, so every dollar figure is your likely share of that job. The report says which share it used and where that number came from. If it is a published industry figure it says so, and you can replace it with your own number in one field.
It takes one file and about a minute.
You will see which of your customers pulled permits, which of those jobs you are not on if your file lists jobs, and which active builders near you are not your customers yet.
