Antarius — custom software development
Not dashboards that look good in a pitch deck — the system of record. The CRM your counter sells from, the job scheduler your dispatcher books from, the ordering portal and driver app your customers and trucks run on. We design it, build it, ship it, and stay on to run it with you.
Most of our clients are companies of ten to a few hundred people running a real-world operation on a stack of spreadsheets, a legacy package nobody likes, and a lot of phone calls. We replace that with software shaped around how they already work.
Job scheduling software for service contractors — plumbing, HVAC, repair — that have to book visits, send technicians, quote work, and get paid.
A CRM and B2B ordering system for retailers, distributors and supply houses — one that understands customer accounts, pricing, terms, and the warehouse behind them.
The part your customer touches — so your office stops being a call center.
A dispatcher will not use a tool that takes eleven clicks to book a job. Our process is built around finding that out early, in the field, before it is expensive.
01
We spend time with the people who will actually use the thing — the counter, the dispatch desk, the service manager. We map the real workflow, spreadsheets and sticky notes included.
02
One core workflow, end to end, working, in weeks — not a slide deck. You click it, break it, and tell us where it is wrong while changing it is still cheap.
03
Then the unglamorous half: roles and permissions, audit trails, integrations, tests, backups, and a deploy pipeline that does not need a person to babysit it.
04
We stay on after launch. Monitoring, support, and a steady queue of improvements, because the business keeps changing and the software has to keep up.
Each case study ships with a working demo running in your browser and a narrated walkthrough that explains every screen — what it does, what happens underneath, and why it is built that way. Nothing is a screenshot.
Plumberium
CRM, storefront, back office and a delivery driver app for a plumbing supply distributor — accounts, orders, invoicing, sales tax and proof of delivery.
Open case studyA plumbing company
Job scheduling software with arrival-window booking, dispatch, quotes, invoicing, purchasing and a customer portal — the whole operation for a Brooklyn service plumber, built to fit how they work rather than how an app vendor assumed they would.
Open case studyAn insurance brokerage
Book of business, carrier and wholesaler relationships, a certificate engine, and a client portal.
Open case studyWe pick tools our clients can still hire for in five years. A typical Antarius build is a TypeScript service over PostgreSQL, a React front end, a native iOS app when the work happens away from a desk, and infrastructure simple enough that one engineer can explain the whole thing on a whiteboard.
That is usually where the project is. Send a couple of paragraphs about the workflow that hurts most and we will tell you honestly whether custom software is the right answer.
