Custom Software

Build Software That Fits Your Process.

By Eduardo Roldan & Luisa S. Avalos, PMP

Off-the-shelf software is built for the average team, not yours. We build custom dashboards, internal portals, and operational tools designed around your actual process — and you own the source code on delivery.

Discuss Your Project

Custom App Development for SMBs focuses on building internal tools, portals, and dashboards that solve specific operational bottlenecks.

We replace messy spreadsheets with centralized, secure platforms designed for how your team actually works.

What We Engineer

  • Operational Dashboards

    Centralize data from Marketing, Sales, and Ops into a single "Mission Control" view.

  • Client Portals

    Give your clients a professional login area to view project status, invoices, and files securely.

  • Legacy System Migration

    Move off ancient on-premise servers to secure, scalable cloud infrastructure.

Frequently Asked

Questions buyers actually ask

What tech stack do you build internal tools in? +
Most builds use Next.js or Astro on the front-end, Supabase or Postgres for data, and Retool for fast internal-only UIs. For mobile we use React Native or Expo. Stack decisions are driven by team capability and total cost of ownership.
Do we own the source code? +
Yes. On full-engagement payment, all source code, infrastructure config and documentation transfer to your accounts and your repository. No ESR lock-in.
How long does a custom internal tool take to build? +
A scoped MVP typically ships in 6–10 weeks. Larger multi-module systems run 12–20 weeks. We work in 2-week sprints with a working demo at the end of each.
Can you integrate with our existing systems? +
Yes — Salesforce, HubSpot, QuickBooks, NetSuite, Shopify, Stripe, Twilio, Slack, and any system with a REST/GraphQL API or webhooks.
Do you maintain the app after launch? +
Optional. We offer monthly retainers covering hosting, monitoring, security patches and small feature changes. You can also take it fully in-house — your code, your call.
How much does a custom app cost? +
Most MVP engagements fall between $25k–$75k. Larger systems are quoted after discovery. We provide a fixed-price proposal for each scope so there are no surprises.

“Internal tools fail when they don't match how your team actually works. I lead the requirements work, design the JIRA workflow around your real process, and make sure ownership doesn't fall through the cracks after launch.”
