We build the tools your business needs and can’t buy.
Every growing company hits a wall where off-the-shelf software doesn’t fit how they actually work. Either you pay for three products to do what one custom tool would handle, or you live with the gap. Vusix Systems is the MSP that also ships software — we build the internal tools your operation needs, and we support them the same way we support the rest of your infrastructure.

We build internal tools, integrations, portals, and small-to-medium custom applications for mid-market businesses. The typical engagement is a system that would be boring to buy as a SaaS product (because no SaaS exists for exactly your workflow) but transformative to have. Engagements range from a two-week integration to a multi-month portal build; most land in the four-to-twelve-week range.
Our stack is pragmatic rather than fashionable. Node.js and Python are our defaults for new builds; .NET for clients with existing Microsoft environments. We use SQLite, Postgres, or SQL Server. We deploy on your infrastructure or ours. We don’t build on proprietary no-code platforms that lock you in.
Every tool we build, we support. You’re not getting a codebase thrown over a wall — we’re the same team that maintains your IT infrastructure. Backups, monitoring, updates, and the phone call when something breaks are all included.
How it works
Discovery (1–2 weeks)
We meet with you and the people who’ll actually use the tool — not just leadership, the operator who’ll be in the thing every day. We document the workflow as it exists today, the pain points, and what “good enough to replace the current process” means. Output: a written scope with user stories and a fixed-price or time-and-materials estimate.
Design and technical review (Week 2–3)
We produce wireframes or mockups for anything user-facing, and a technical design document for the integration and data model. You sign off on both before we write code. The design step is where we catch scope problems — it’s dramatically cheaper to redesign a wireframe than to rebuild a shipped feature.
Build (2–10 weeks depending on scope)
Iterative development with weekly demos. We ship working software to a staging environment early and keep it there, so you see progress every week. Your operators can test against staging throughout — changes that would’ve been discovered at launch get caught at week three instead.
Launch and handoff (1 week)
Production deployment, live user training, and a written operations runbook. The tool goes into our managed environment — backed up, monitored, patched — on the same terms as everything else we manage.
Ongoing support (retainer)
A small monthly retainer covers bug fixes, version updates, minor features, and priority response when something breaks. Bigger features get scoped as small projects. Plan on 10–15% of the original build cost per year for ongoing evolution.
What’s included
- Discovery and scoping — workflow documentation, user interviews, written scope
- Design — wireframes, mockups, technical architecture documents
- Full-stack development in an appropriate stack (not a mandated one)
- Third-party integrations — QuickBooks, Square, Microsoft Graph, Level RMM, IT Glue, Stripe, Zabbix, and more
- Authentication and security — SSO, magic link, MFA, role-based access control
- Hosting and deployment — your cloud, ours, or on-prem; your choice
- Live user training sessions
- Operations runbook — written documentation of how to run and troubleshoot the tool
- Ongoing maintenance retainer — bug fixes, dependency updates, minor features
- Source code delivery — you own the code from day one, clean license
What makes Vusix different
We ship production software ourselves, not just for clients.
Vusix Quoter is the quoting platform we use to run our own business — Node.js, better-sqlite3, PM2, Apache, built from scratch. Our client portal is a multi-tenant Express/EJS app we built and operate. Software built by people who ship software in production is fundamentally different from software built by a dev shop that ships and walks away.
We support what we build.
Most custom software engagements end at launch. Your IT provider then inherits a codebase they don’t understand, and six months later you’re quietly paying someone to rewrite it. We don’t create that situation because we’re the ones operating it from day one.
We write scopes we can honor.
Custom development has a reputation for scope creep and blown budgets. We do enough discovery up front to write a scope with real user stories and a real estimate — and then we deliver against it. When scope genuinely needs to change, we’re transparent about cost and timeline impact before we make the change.
