The internal software a Tustin business runs on — scheduling, client portals, invoicing, an owner dashboard — built single-tenant and handed over with the source. No per-seat platform fee.
Tustin sits in the middle of Orange County, equal parts Old Town charm and Tustin Legacy growth — 80,000 people, a base built on professional services, healthcare, family retail, and a growing layer of tech and light manufacturing. The businesses skew white-collar and appointment-driven: practices, advisories, service firms that bill by the engagement. They're organized enough to look buttoned-up from the outside and held together by a spreadsheet on the inside, the way most professional-services shops are.
The friction is the white-collar version. A practice schedules in one tool, bills in another, and reconciles them at month-end. An advisory firm onboards each client through a checklist living in a partner's head. A service business tracks engagements and retainers in a sheet only one person fully understands. The work is billable and valuable; the admin around it quietly consumes hours that could be billable too.
A Tustin operator doesn't need an enterprise practice-management suite with a per-seat fee. The fix is a small single-tenant app that handles the three to five workflows this business runs on — scheduling, a client portal, billing that drafts itself, a clean dashboard — built around the real process and owned outright. No subscription scaling with the team.
A professional-services firm in Tustin Legacy. Engagements, retainers, and team time live across a CRM and a spreadsheet, reconciled by hand each month. We build an internal app: active engagements with status, retainer burn-down, time logged against each, and invoicing that drafts from logged work through Stripe. The month-end reconciliation shrinks to an afternoon.
A healthcare or specialty practice. Appointments, intake, and payment reconciliation run on disconnected tools and a front-desk binder, and recalls slip. We build a scheduling and intake app: the day's appointments, automatic recall reminders through Resend, and a one-screen daily reconciliation. Just the front office, not a full clinical system.
An advisory or consulting practice in Old Town. Client onboarding lives as a checklist in a partner's head, and documents scatter across email. We build a client portal: each client sees their status and documents, an onboarding checklist drives the process, and the partner sees every account on one screen. The checklist stops living in someone's memory.
This is right for you if you run a real Tustin business, you know the three to five workflows eating your week, and you'd rather own software than rent another seat-based subscription. It's not right if you want a multi-tenant product to sell to your own clients — that's a bigger build, and I refer it out.
OC — in-person reachable in about 90 minutes from the San Diego studio, and I make the drive when a build calls for it. An hour walking your real process beats a long requirements doc.
