Custom software for commercial service businesses
From the estimate
to the invoice.
I build focused internal tools that follow up on open estimates, collect what technicians record in the field, and get completed work invoiced. Your team keeps its current accounting and field-service systems.

Nothing falls through.↗

You already spent time on the estimate.
Don't lose it to a missed follow-up or a slow invoice.

How I can help
One workflow.
Fixed first.
We start with the steps between an estimate and an invoice, and we fix the one that costs your business the most.
01◎
Map where
jobs get stuck.
After a free first conversation, a workflow audit follows real jobs from the estimate to the invoice. Its cost is credited toward the build.
- A map of the current workflow
- What the problem costs you in time or revenue
- A recommended solution and a price for the build
WORKFLOW AUDIT
02⇄
Close the gaps
between steps.
Build one focused tool for the step that costs you the most, around the systems you already use. For example:
- Reminders for estimates that need a follow-up
- An invoice-ready packet for each visit
- A record of approved extra work not yet billed
FOCUSED BUILD
03</>
Keep it
working.
After launch, the tool stays hosted, backed up, and up to date, with a defined amount of support each month.
- Hosting and monitoring
- Backups and updates
- Support within an agreed limit
ONGOING CARE
What could that look like?
Start with the job
that slipped away.
A few examples of the problems we could work on together.
↗"We send estimates and never hear back, and nobody follows up."
Track every open estimate and prepare the follow-up before the customer goes elsewhere.
↗"Our office re-types technician notes before every invoice."
Collect notes, photos, and materials once, in the shape the office needs to bill.
↗"Extra work gets approved in the field and never gets billed."
Record each approval with its labor and materials, and track it until it reaches an invoice.
↗"Finished jobs wait days for a missing photo or signature."
Flag what is missing while the technician can still fix it, and alert the office when a job stalls.
Working together
A clear path.
A human conversation.
- 01
Walk through a recent job
A free conversation about what happened between the estimate and the invoice.
- 02
Audit the workflow
If the problem is worth solving, I map it, work out what it costs you, and price a bounded solution.
- 03
Build it. Make it usable.
We agree on what "done" means before building, then check the tool against your real jobs.

that earns its keep.
WORKFLOWS / INTERNAL TOOLS / AI Hi, I’m Jason
An engineer.
In your corner.
My background is in full-time software engineering, with experience in applied AI and building custom software. Now I’m bringing that experience directly to commercial service businesses.
I’m interested in the practical questions: Who follows up on an open estimate? Who re-enters information from the field? What stops an invoice from going out?
You know your trade and your customers. I bring the technical experience to build a tool that fits the way your team already works.
