AI invoice coding for contractors: an agent reads vendor bills and fills in the job and GL code

Perry Contracting, Inc.

What they did with AI

Perry Contracting, a construction contracting firm in Norwood, Ohio, coded every vendor invoice by hand: project managers marked up paper invoices with the job and GL account, and a long-tenured accounting manager keyed them into the accounting software. With that manager nearing retirement after 30 years, the company had IT firm N Solutions build an AI agent on Microsoft Copilot that reads each invoice, works out the likely GL code and job details, and prefills the entry. The invoice then goes to the project manager in Microsoft Teams to review and confirm; nothing posts without a human check. A Power App shows each PM what is outstanding, and approved invoices are imported into the accounting software automatically. N Solutions estimates the process will save Perry 200 to 300 hours a year and captures the accounting manager's know-how so the next person can take over.

AI permit research, job-site daily logs and change-order scans at an Alabama builder-remodeler

Old Number One Customs (Jake Bartol, Auburn, AL)

Jake Bartol, owner of Old Number One Customs, a licensed residential builder and remodeler in Auburn, Alabama, describes the AI running on every active project. An AI notetaker on site turns conversations into daily logs that sync to project management. A daily scan of client communications flags possible scope creep, and within 24 hours the client gets a written, priced change order to approve or decline. AI permit research pulls county and city code requirements and overlays such as historic districts, Lake Martin shoreline rules and FEMA flood zones, which he then confirms with the permit office. AI also gives tier-based starting estimates from the site's project configurator and drafts invoices, change orders and emails. He says AI handles the information work that used to take 40% of his time.

Automate cost-plus draw billing and receipt capture

Sustainable 9 Design + Build

Minneapolis custom builder Sustainable 9 runs open-book, cost-plus projects up to $6M+ and used to build every draw in a giant spreadsheet. It now pulls costs automatically from bank feeds, vendor emails and field receipt photos into an AI construction-accounting tool, codes each one to job and cost code with approvals, and generates client-ready draw packages. The builder reports billing went from 80+ hours a month to about 2 hours per cycle and that it recovered thousands in receipts that used to go unbilled.

Cut construction bookkeeping time in half with automated AP coding

Shrock

Shrock grew from a family Amish construction business into several entities (custom homes, restoration, prefab), and manual AP and credit-card entry kept coding costs to the wrong job or cost code. It automated AP and card entry with structured approvals and real-time job costing across entities. The controller reports bookkeeping fell from 26-30 hours a month to 12-16 per entity, with job-cost reports leadership can now trust.
