One engine, eight trades. This is the front office of the Owned Office.
It is no longer sold on its own. DArnTech sells one product, the Owned Office: your whole back office on one box in your building, with your history moved onto it and checked to the penny. What you see here is the front-office layer of that box, and it is on this page as evidence you can click rather than as a plan you have to trust. Read what the Owned Office is →
If you already subscribe to this suite, nothing changes. Your instance keeps running, your support is unchanged, and you keep your export. The monthly plans are off the public menu; your service is not.
What it is, plainly
An operations tool for small service shops, and one of the systems that runs on the Owned Office. 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 is yours — you own it, you can export it, you can take it elsewhere whenever you want.
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. On an Owned Office install it runs on your box, beside your books, under your own sign-in.
The whole suite is published with demo data at acme.darn-tech.com. DArnTech built it and ran it; what you see is a snapshot taken on 18 September 2026, so the pages read but the forms don’t submit.
What you get
Pick your trade — every demo is a captured snapshot
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, on its own. Quotes and job records yes; tax and books no. On an Owned Office install the books sit on the same box and your history is moved there with a penny-exact check: read how Move works.
- 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 look at it
Start at acme.darn-tech.com — pick your trade and click around; it's the real software with demo data, no signup. If what you see is what your shop needs, the next step is the Owned Office, not a subscription to this one piece: the three moments are on the services page, and the day that starts it is the Move dry-run.
