Sound familiar?

The off-the-shelf trap

You pay $3,000/month in SaaS subscriptions for tools that only do 60% of what you need

Your data lives on someone else's server. If they shut down or hike prices, you're stuck

You've duct-taped 6 tools together. Integrations break, data is inconsistent, the team is confused

You can't add features your customers keep requesting because the vendor roadmap says no

These are exactly the problems a custom SaaS platform solves.

How It Works

From idea to live platform

01
Discovery call
We learn your business model, target users, and what the platform needs to do in week one.
02
Architecture & scope
We define the tech stack, database schema, feature set, and a fixed-price quote. No surprises.
03
Phased build
We ship in 2-week sprints. You see working software from week three, not at the end.
04
Launch & handover
Full deployment, documentation, and code handover. You own everything source code and all.
Who It Is For

Built for businesses like yours

Startups building a product
You have a SaaS idea and need a technical co-founder-level team to build it fast without giving up equity.
Agencies replacing client tools
Your clients need software tailored to their workflows. White-label it and resell it under your brand.
Businesses replacing off-the-shelf
You outgrew Salesforce, HubSpot, or monday.com and need something built around how you actually work.
Internal tools that became products
That spreadsheet or internal app is becoming a real product. Time to turn it into a proper platform.

We replaced three SaaS subscriptions that were costing us $4,200 a month. SoftProgrammer built us a single platform in 11 weeks. The whole thing paid for itself before the end of the year.

Common questions

How long does it take to build a SaaS platform?
Most platforms go live in 814 weeks depending on scope. We ship in phases, so you see working software from week three.
How much does custom SaaS development cost?
Pricing depends on the feature set. Most clients invest between $15,000 and $60,000 for an initial platform. We provide a fixed quote after our scoping call no hourly billing surprises.
Do I own the source code?
Yes, 100%. We hand over all source code, database schemas, infrastructure configs, and documentation at launch. No licensing fees, no lock-in.
Can you build multi-tenant architecture with separate billing per customer?
Yes. Multi-tenancy with Stripe billing (plans, trials, seat-based pricing, usage billing) is our standard pattern.
What tech stack do you use?
We typically use Next.js or React frontends, Node.js or Python backends, PostgreSQL or Supabase, and deploy on AWS or Vercel. We can match your existing stack if needed.
Can you integrate with our existing tools?
Yes. Slack, Salesforce, HubSpot, Zapier, and any REST API are standard integrations. We document every API endpoint.
