One engine, eight trades. Booking, job boards, and customer status for small shops.
What it is, plainly
A self-hosted operations tool for small service shops. Customers book online, the day's work lives on one board, quotes get approved with a tap, and customers follow their job from a link instead of calling you. Your customer data lives on your subdomain (yourshop.darn-tech.com) — you own it, you can export it, you can take it elsewhere if you ever leave.
Every trade runs the same DArnTech-built engine with a different trade on top — the auto-repair shop gets vehicle records and parts-ETA states, the tutor gets recurring slots and a family progress portal. Not a wrapper, not a reseller agreement — DArnTech (Indianapolis) built the engine and operates and supports your instance directly.
The whole suite runs live with demo data at acme.darn-tech.com. Real working software, not mockups — click into any trade below and use it.
What you get
yourshop.darn-tech.com on infrastructure DArnTech operates. Full export anytime. Your data is not pooled with other operators' data. Not sold, not used for ads.
Pick your trade — every demo is live
Your trade not listed? The engine retargets — each new trade is a configuration of the same core, not a new product. Ask about yours.
What it's NOT
Honest about scope — this is for the solo operator and the 2–5 person shop that's outgrowing pen-and-paper or Square Appointments, not for the enterprise field-service buyer.
- Not a sales CRM. Your customer list lives in the system but it's not a pipeline. If you want lead-scoring and email campaigns, this isn't that.
- Not fleet-scale dispatch. The board fits a small crew's day. If you run 5+ vans and need route optimization, you're outside this product's fit.
- Not accounting. Quotes and job records yes; tax and books no — the export means your bookkeeper gets clean data. When you want books you own too, that's its own lane: accounting migration, fixed price per system.
- Not a marketplace. It doesn't send you leads and it doesn't put your customers in anyone else's funnel. Your customers stay yours.
How to try it
Start at acme.darn-tech.com — pick your trade and click around; it's the real software with demo data, no signup. Then reach out and we'll spin up an instance configured for your shop's services and prices. You can take real bookings on it during a 2-week trial. If it fits, first paid month starts after the trial. If it doesn't, the instance comes down, you get a full export, and there's no lock-in.

Who's behind it
Darren Arney, owner-operator of DArnTech LLC in Indianapolis. Senior lab automation engineer (9+ years) and AI engineering as the day job — this is the small-business software line that runs alongside. The engine is built and operated by DArnTech, hosted on infrastructure I own and operate. Real person, not a SaaS support queue.
No company Facebook or Instagram — if you'd rather meet in person to size up whether this fits, happy to. Any place around Indy that works.
