Purchasing & cost control for homebuilders

The homebuilder ERP with AI staff built in.

Your vendor's contracted price becomes the job budget, the budget becomes the purchase orders, and every bill reconciles against them — nothing typed twice, nothing bought at the wrong price. The AI drafts the busywork; you approve it.

How it works

One chain, from contract to bill.

Most construction software stores what someone typed. AD ERP derives it — so the number on the PO is the number you negotiated, every time.

1

Contract price

Every vendor has a price per cost code, locked to a scope. One upload loads them all.

2

Job budget

Takeoff quantities × contract prices. The budget builds itself, per plan, per lot.

3

Purchase orders

Buy out a whole house in one pass. Committed cost updates the moment a PO is issued.

4

Bills

Invoices reconcile against the PO. Anything off-price or over-scope gets flagged, not paid.

Product

Everything the job needs, in one system.

Plans and takeoffs, estimating, budgets, vendor contracts, purchase orders, scheduling, bills, draws, change orders, warranty — and portals for your trades and homebuyers.

Know your margin before it's gone

Budget, committed, and actual side by side — per job, per cost code, per division. Variance shows up when a PO is issued, not when the invoice lands.

Your SOPs, written into the screens

How your company runs a job, on the screen where the work happens. One switch in the top bar turns numbered steps on for a new hire — and off for someone who's done it a thousand times.

app.aderp.com/vendor-confirmations

Your trades confirm without an account

Vendors get a link — no login, no seat to buy. They acknowledge the PO and confirm or propose a date. Accept it and the schedule updates itself.

Plans & takeoffs

Quantities per cost code, per plan, feeding budgets automatically.

Sales & contracts

Leads to signed homebuyer, options priced into the job.

Schedule

Every job, every trade, every date — with vendor confirmations.

Bills & draws

AP against POs, lender draws, retention, 1099 totals.

Change orders

Scope changes with client sign-off before the money moves.

Dashboards & API

Reporting out of the box, and your data open through an API.

AI staff, built in

It does the busywork. You approve it.

Two agents work inside the system, on your data, under your permissions. Neither one can write anything on its own.

app.aderp.com/purchasing-assistant

A purchasing manager that never writes without you

Tell it “HVAC costs are up 4% this quarter — raise every HVAC contract price.” It finds every affected line, works out the new numbers, and stages one approval card showing the old price beside the new one. Nothing moves until you press Approve.

Pricing

Published prices. No volume quotes.

You'll never get a custom quote based on how much you build, and your price won't climb because you had a good year.

How we compare

Real cost control, without the ERP rollout.

Questions builders ask

The short answers.

How long until we're actually running on it?
Days, not quarters. Your vendors and their contract prices come in on one spreadsheet upload — that single file is most of the setup. The $2,500 covers us loading it with you and checking it against what you're actually paying.
Do my subs have to buy seats or learn software?
No. Vendors get a link — no login, no account, no cost. They acknowledge the PO and confirm or propose a date from their phone. Homebuyers are free too.
We already use Buildertrend. Does this replace it?
For most builders, yes — AD ERP covers the same build coordination and adds the purchasing and cost control that project-management tools don't do. If you'd rather keep it, run us on the money side and keep it for field coordination; your data stays reachable through the API either way.
Can the AI change prices behind my back?
It can't write anything. Every change it drafts — one price or five hundred — is staged as a proposal showing the old value beside the new one, and it stays there until a person presses Approve. Every approval is logged with who and when.
Who can see cost and margin?
Whoever you say. Access is set per person across fourteen areas, and it can be narrowed to specific jobs. Someone running two communities doesn't see the rest of the portfolio, and field staff don't see margin at all.
Does it work with QuickBooks? Is our data locked in?
AD ERP is built to sit beside it: the job-cost side lives here — POs, bills, draws, retention, 1099 totals — and every bill and vendor carries a sync status for your books. Data moves out through clean exports and the API, so nothing is ever locked in.
Why this exists

Built inside a real purchasing operation.

AD ERP was built by the person who ran buyout for a builder doing 1,000+ homes — vendor pricing, bid evaluation, cost codes, plan and option structures. Every workflow in it was designed against live jobs, not customer interviews.

“Most construction software stores the work. It never does it. The variance shows up after the money is already committed — every time. AD ERP makes that structurally impossible.”
Arnaud Durand · Founder, AD ERP · Orlando, Florida

Twenty minutes on a real job.

No slides. We'll put a live job on screen, build a budget from vendor contracts, turn it into purchase orders, and let the AI draft a price change you approve. If it doesn't fit how you buy, you'll know inside twenty minutes.
