Custom web apps and automation, for the shop, the practice, the studio, the site
The kinds of operations we keep showing up for: small enough that every staff hour matters, complex enough that off-the-shelf tools never quite fit.
Four kinds of operation. One pattern underneath.
Every one of them outgrew spreadsheets and generic SaaS, and none of them can justify what an enterprise consultancy charges. If you have repeat customers or members, collect data or require a login, and still run part of it by hand, you’re in here somewhere.
The Shop · Trades & Routes
HVAC, plumbing, electrical, painting, roofing, cleaning, dispatch.
Quoting that reads supplier pricing in real time. Job intake from a phone. Route logs that don’t live in someone’s head. The repetitive paperwork that comes between an estimate and an invoice.
The Practice · Law & Medical
Two-to-ten-person practices in the northwest suburbs.
Client intake, appointment reminders, document routing, billing follow-up. The repetitive work that eats staff hours every day.
The Studio · Members & Bookings
Gyms, dance and martial arts, salons, med-spas, instructors.
Booking that doesn’t bounce between three apps. Memberships, packages, and attendance in one place. And because it’s instrumented, you finally see which class times actually fill, and who went quiet three weeks before they cancelled, while there’s still time to do something about it.
The Site · Brochure Sites, Rebuilt
Organizations whose website is a business card that stopped changing years ago.
The most common conversion we run. Your site keeps its content and its brand, and gains a login, a customer portal, and a memory. It installs on a phone without an app store, and it starts producing behavioral data a static page never could.
We donate builds to the organizations that need them most.
Real engineering for organizations running on volunteers.
GraceZero builds full digital platforms for volunteer organizations, pro bono, start to finish. The first is live: TackleAgent, the operational platform for a youth football league serving hundreds of families, ran the league’s 2026 equipment-pickup day on a 248-player roster at tackleagent.com. The second, a Scout troop platform, is in build on the same standard.
These aren’t portfolio exercises. They’re real applications serving real users, built to the same standard as every paid engagement. If you found GraceZero through one of those apps, that’s the work. The full case study is on the work page.
