What this is not
Not a one-time development project. Not a replacement of your product. Not a migration away from your system. Not a generic software agency offer.
Partnership model for desktop software vendors
Your desktop product stays. New recurring revenue comes from web and mobile.
We help desktop software vendors add a modern web/mobile layer to their existing products — without rebuilding the core system or moving customers away.
No rewrite. No migration. No competition with your core product.
Desktop stays core
Web/mobile layer added
Joint customer value
Recurring revenue
No full rewrite
Shared growth
This is not outsourcing. This is a joint product model.
We do not simply build features for a fixed fee. We create a web/mobile extension together with the desktop software vendor, launch it to existing customers, and grow recurring revenue together.
How we work
Your desktop product remains the core. We build the web/mobile extension. You keep the customer relationship. We launch to your existing customers together.
Why it matters
An optional paid add-on for current customers creates a monthly subscription model, shared commercial upside, and continuous product improvement.
The problem
Desktop customers now expect web and mobile access, but rewriting a working product is risky.
Many successful vertical software products are mature desktop or on-premise systems. They already have loyal customers, trusted workflows, and a stable business base.
But customer expectations have changed. Buyers now expect mobile access, remote dashboards, customer portals, document upload, approvals, notifications, field workflows, online status tracking, and self-service access from anywhere.
Building a full web and mobile team is expensive, slow, and risky. A full rewrite can put the core product and customer trust at risk.
The Solution
Add a web/mobile layer around the existing product and monetize it as an add-on.
Your system remains the source of truth
We integrate with your existing desktop or on-premise product. Your data model, business logic, and customer relationships stay exactly where they are.
The desktop system remains the core. We build a separate web and mobile module around it that connects through APIs, sync, or secure database access.
Recurring revenue from existing customers
Your existing customers can pay a monthly subscription for web and mobile access to your product. That creates a new recurring revenue stream without replacing your core license model.
You keep the customer relationship, the product ownership, and the core business. QMX handles the web/mobile technical delivery and maintenance.
Pick what works for your market
Start with the module most valuable for your customers: owner dashboards, customer portals, mobile warehouse apps, field-worker apps, document capture, approval workflows, reports and analytics, or B2B ordering portals.
We do not rebuild the entire product. We start with one commercially valuable module and grow from there.
How the partnership model works
Existing desktop product → integration layer → web/mobile modules → recurring revenue.
Existing desktop product
Your product remains the source of truth. We learn its workflows, data structures, and commercial role before we extend anything.
Integration layer
We connect through a connector, API, sync layer, or secure access path so the web/mobile layer can sit around the core system.
Web and mobile modules
We deliver the first commercially valuable module: customer portal, mobile workflow, owner dashboard, or another paid access point.
Recurring revenue
The new module is sold as an optional add-on to existing customers, creating a shared monthly revenue stream instead of a one-off project.
Is this model right for your software company?
This model is designed for vendors with an existing desktop product, loyal customers, and a clear opportunity to add paid web/mobile access.
Good fit
- A mature desktop or on-premise software product
- Existing paying customers

- Willingness to launch a joint add-on to existing customers
Not a fit
- Already have a modern SaaS product
- Already have strong mobile apps and customer portals
- Only need temporary outsourcing capacity
- Want to replace the desktop product completely
- Do not want a recurring revenue model
- Do not have an existing customer base

This is the model we want to repeat with other desktop software vendors.
