Built around how you work.Web apps, dashboards and internal tools.

What we build

Everything a business system needs.

Twelve building blocks, put together differently for every client.

Insight

Dashboards and reporting

The numbers that matter on one screen, from sales this month to jobs in progress.

Sales

CRMs and pipelines

Leads, customers and deals in one place, with the stages your sales process already uses.

Customers

Customer portals

A place for customers to sign in, check status, pay and send files.

Operations

Scheduling and dispatch

Calendars, routes and crew assignments, with the day's jobs on every phone.

Payments

Payments and invoicing

Invoices, deposits, card payments and payouts, built on Stripe.

Accounting

Accounting sync

Customers, invoices and payments flow into QuickBooks Online, so nobody types them twice.

Paperwork

Documents and e-signatures

Estimates, contracts and reports filled from your data, then signed online or in person.

Security

Roles and permissions

Owners, office staff, crews and customers each see what they need and nothing else.

Automation

Automations and scheduled jobs

Reminders, follow-ups and nightly tasks that run on their own.

Integrations

APIs and integrations

Connections to HighLevel and the other tools you already pay for, plus an API of your own.

Data

Data migration

Your spreadsheets and old systems moved in, with totals checked against the originals.

Back office

Admin panels

Screens to manage users, settings and data without calling a developer.

One system.Every seat.

Good business software fits everyone who touches it. These are real screens from software we've built for the office, the crew and the customer.

Contracts become templates with every field already placed. Customers sign online or in person, and each signed copy keeps its own record of who signed and when.

How it works

From first call to launch.

Five steps, with something real to look at after each one.

  1. 01

    Discovery

    We learn how your team works today, what slows it down and what the software has to do.

  2. 02

    Written plan and quote

    Screens, features, timeline and price in writing, before any work starts.

  3. 03

    Design

    Clickable designs of the key screens. You approve them before we write code.

  4. 04

    Build in weekly milestones

    Every week there's a working build for you to try, so feedback lands early.

  5. 05

    Launch and support

    We move your data in, help your team get started and stay on for what's next.

Questions? Answers.

How much does custom software cost?

It depends on the scope. A tool that replaces one spreadsheet costs far less than a platform with mobile apps. After a short call we send a written plan and quote, so you know the price before any work starts.

How long does it take?

A focused internal tool can take a few weeks. A full platform with web and mobile apps takes months. Your written plan has the timeline, and you try a working build every week along the way.

Who owns the code?

You do. Ownership is written into the plan, and the code lives in a repository your company controls, so you can bring in any developer later.

Can it connect to the tools we already use?

Usually, yes. We've built Stripe, QuickBooks Online and HighLevel integrations into LightMaster and connected SignMaster to Claude and ChatGPT. If a tool has an API, we can connect to it.

Where is it hosted?

We can host it on modern platforms like Vercel and Supabase or deploy to a cloud you already use. Either way, hosting and its monthly cost are spelled out in your plan.

Do you help after launch?

Yes. We handle hosting, fixes and new features for as long as you want us to. LightMaster Mobile, for example, has shipped six updates since its September 21 launch.
