Applications

Apps that replace the spreadsheet.

Web and mobile applications with real logins, real data, and workflows built around how your team actually operates.

There's a moment in every growing business where the spreadsheet stops working. Three people are editing it, the field crew can't open it on a phone, and nobody trusts the numbers. That's an app problem.

We build web and mobile applications around the workflow you already have — the way jobs actually get scheduled, the way approvals actually happen — instead of forcing your team into someone else's software.

That means real accounts and permissions, a proper database with row-level security, dashboards that answer the question you open the app to ask, and offline-tolerant behavior for crews working where signal dies.

What we build

Where we go deep.

Internal tools & dashboards

Operational software that replaces spreadsheets, group texts, and paper.

Client & customer portals

Branded logins where your clients see documents, progress, and invoices.

Mobile & field apps

Phone-first tools for crews: photos, checklists, time, and offline capture.

Auth & permissions

Roles, org accounts, SSO-ready login, and row-level data security.

Integrations & automation

QuickBooks, Stripe, Twilio, email, calendars, and custom API work.

AI features

Estimating assistance, document parsing, summaries, and smart search.

Depth

How we scope an app without burning your budget

Custom software goes wrong when everything is built at once. We ship in slices that earn their keep.

Start with the painful loop

We find the one process costing the most hours per week and build that first. It goes live in weeks, not quarters, and it pays for the next phase.

Model the data once, properly

Bad schemas are the most expensive mistake in software. We design the data model up front so features two years out don't require a rewrite.

Design for the worst device

If it works one-handed, in gloves, on a cracked phone with one bar, it works everywhere. Field usability is a design constraint, not a nice-to-have.

Own your code and your data

You get the repository, the database, and the deployment. No lock-in, no per-seat surprise when you grow.

FAQ

Common questions.

Do I need a native app from the App Store?

Usually not at first. A fast installable web app covers most field and portal use cases and ships far cheaper; we go native when push notifications, hardware, or store presence genuinely require it.

What does a first version cost?

It depends entirely on scope, which is why we start with a paid discovery that produces a fixed-price build plan before anyone commits to a number.

Can you take over an existing app?

Often yes. We audit the codebase and data first, then give you an honest read on whether it's worth extending or rebuilding.
