The spreadsheet that runs the company
Most contractors have one: the master sheet with every job, every draw, every retainage number. One person maintains it. Everyone fears breaking it.
Procore and Buildertrend are good platforms, but a 15-person GC often needs 10% of what they sell and one thing they do not have: your exact billing and reporting logic.
What I build for contractors
Purpose-built, connected to your accounting, owned by you.
- Project tracking shaped around your phases, draws, and retainage
- Progress billing tools that handle AIA-style applications without the re-typing
- Client portals where owners see schedule, photos, and payment status
- Change-order workflows with approvals that hold up later
- Automated weekly owner reports pulled from real job data
Real work, not theory
I built an operations app for a commercial contractor that runs their jobs from bid to final payment, including AIA-style progress billing that used to eat their office days every month. That is one of 40+ systems I shipped this year.
The offer, in one paragraph
I work as the AI systems builder on your team: $4,000 a month, published price, no contract. Your first working software lands inside 14 days of an approved plain-English plan, and month one is refundable if you are not happy. You own the code, the data, and the accounts from day one. The full offer, guarantees included, is at offer.busqueneil.com, and the pricing logic is unpacked in what custom software costs in 2026.
Common questions
We use Procore. Is custom still worth it?
Sometimes the answer is no, and I will say so on the call. Custom usually wins for the gap tools: billing logic Procore does not model, owner reporting, or connecting Procore to your accounting without manual exports.
Can you handle progress billing and retainage?
Yes. I have built AIA-style progress billing with retainage math that rebills correctly every period. It is exactly the kind of logic off-the-shelf tools get almost right, which is worse than wrong.
What does it cost?
$4,000 a month. First working version in 14 days. Month one is refundable, and you own the code, data, and accounts from day one.
