Custom Software and SaaS Development Built Around How Your Business Works
Off-the-shelf tools force your team into someone else’s process. We build web applications, SaaS products, internal tools and integrations that fit your workflow, connect your existing systems and scale as you grow.

Software we design and build
Whether you need a customer-facing product or an internal tool for twenty users, we start from your real process, then design software that removes friction from it.
SaaS MVPs
Multi-tenant architecture, sign-up and onboarding, subscription plans, billing with Stripe or Razorpay, and usage limits per plan.
CRM and ERP-lite tools
Lead pipelines, quotations, orders, inventory, dispatch and invoicing in one lightweight system shaped to your team.
Admin dashboards and reporting
Live KPIs, filters and exports that pull from your database and third-party tools, with scheduled email reports.
Customer and vendor portals
Self-service portals where customers track orders and download invoices, and vendors update stock, pricing or delivery status.
API integrations
Connections with Razorpay, Stripe, Shiprocket, Zoho, HubSpot, Tally and other accounting tools so data flows without re-entry.
Legacy modernization
Step-by-step migration of old systems to a modern stack, with data migration and parallel running to avoid disruption.
Security and access control
Role-based permissions, audit logs, encrypted secrets and regular backups built in rather than added later.

Why EcommFusion: based in India, working worldwide
Software projects fail when scope is vague and communication is thin. We keep both tight, whether you are across town or across the world.
NDA & full ownership
NDA before discovery. You own the source code, database and intellectual property, with repositories in your account.
Time-zone overlap
IST overlaps UK and European business hours, the UAE works the same day, and US teams can meet us in their mornings or evenings.
Transparent milestones
Each milestone has written acceptance criteria and a staging demo before it is invoiced.
Simple payments
Bank transfer or UPI in India; Wise, PayPal or international wire transfer for clients abroad.
Custom software and SaaS FAQs
Why build custom software instead of using an off-the-shelf tool?
Off-the-shelf tools are a good start, but many businesses outgrow them or pay for features they never use while missing the ones they need. Custom software fits your exact workflow, integrates with your existing systems and has no per-user license fees. We will also tell you honestly if an existing tool is the better option.
How much does custom software development cost?
Custom tools and SaaS MVPs start from ₹1,00,000 or $2,500. Cost depends on modules, user roles, integrations and data migration. Final quote after a free consultation.
Can you build a multi-tenant SaaS with subscription billing?
Yes. We build multi-tenant SaaS applications with separate data per customer account, plan-based feature limits, trials, and recurring billing through Stripe or Razorpay, along with a super-admin panel to manage tenants.
Can you integrate with Tally, Zoho or our existing systems?
In most cases, yes. We integrate with Razorpay, Stripe, Shiprocket, Zoho, HubSpot, Tally and other accounting or ERP tools through their APIs or supported connectors. We review your systems during discovery and confirm what is possible before we quote.
Do you work with international companies and agencies?
Yes. We work with businesses and agencies in the US, UK, UAE, Australia, Canada and Europe, including white-label engagements under NDA. We use shared boards, staging demos and scheduled calls that fit your time zone, with payment via Wise, PayPal or wire transfer.
Will we own the source code?
Yes. The source code, database and documentation belong to you. Repositories and cloud accounts are set up in your name, so you can bring development in-house or change vendors at any time.
