SaaS Development
From first paying customer to a platform
DanixSoft builds SaaS products for founders and adds engineering capacity to existing SaaS teams, covering tenancy, billing, permissions, admin tooling, and onboarding alongside the features customers pay for.
We help founders launch SaaS products and help existing SaaS teams add capacity. That means the unglamorous parts done properly — tenancy, billing, permissions, admin tooling, and onboarding — alongside the features your customers are paying for.
What's included?
Everything you need to ship a production-grade solution.
SaaS MVPs
The smallest product that can win a paying customer, scoped in a written spec and shipped in two-week sprints.
Multi-Tenant Architecture
Tenant isolation, per-tenant configuration, and data models that will not need a rewrite at 100 customers.
Subscription Billing
Stripe plans, trials, credits, usage-based billing, and dunning.
Admin & Support Tooling
Control planes for customers, plans, events, and support tickets — like the Lens admin panel.
Analytics & Dashboards
In-product analytics for your customers and operational metrics for your team.
Integrations Marketplace
OAuth-based integrations with CRMs, email, calendars, and messaging tools.
How does a project run?
Transparent, milestone-driven delivery from day one.
Product Scoping
Define the core value, the first customer, and the smallest release that proves it.
Architecture
Tenancy model, billing model, and data model agreed in writing before building.
Sprint Development
Two-week sprints with a demo each time — you can put early builds in front of prospects.
Launch Readiness
Security review, monitoring, backups, and onboarding flows before real customers arrive.
Iterate & Scale
Post-launch support, then ongoing development as usage and requirements grow.
Which technologies do we use?
Battle-tested tools we rely on to deliver.
SaaS Development in practice
Case studies where this service was part of the build.

FramewiseAI website builder: describe a business, get a finished site
Challenge: Small businesses need a professional website without hiring a developer, but most builders hand them a template marketplace and leave the structure, copy, and design decisions to them.
Read the case study
Repo DiveA daily training system for reading production code
Challenge: Developers who want to learn from real-world code have no structured way to do it. Browsing GitHub Trending is easy to skip, and an early version of the product picked repositories at random, so what someone had already studied never changed what came next.
Read the case study
BulkReachMulti-tenant bulk and scheduled messaging for Slack and WhatsApp
Challenge: Teams that announce to many Slack channels or WhatsApp contacts need sends that respect rate limits, survive timeouts, keep each customer's data isolated, and never message people who have not opted in.

How much does it cost?
Product / Growth: ~$10k–$30k+
Typically 2–4 months
A tightly scoped SaaS MVP can start in the MVP tier; most SaaS platforms with billing and integrations are Product / Growth.
Typical starting points, not quotes. Final pricing depends on scope and is fixed in writing after a discovery call.

Common questions about this service.
How long does it take to build a SaaS MVP?
Typically 4–8 weeks for a focused MVP, and 2–4 months for a platform with billing, integrations, and admin tooling.
Which stack do you use for SaaS?
Usually Next.js or React with a Node.js or Django backend on PostgreSQL. We choose based on your team and product, and write the reasoning down.
Can you work with our existing SaaS team?
Yes. We regularly join existing codebases and work inside your repository, tools, and code-review process.
