We design and build multi-tenant SaaS platforms for founders and businesses in Noida and Delhi NCR — subscription billing, onboarding flows, usage analytics, and the infrastructure to grow from 10 customers to 10,000.
Web Development Service #11 / 58
Most SaaS products fail at growth, not at launch. They are built to demo well but crack under real multi-tenant load, churn customers due to poor onboarding, and stall because billing cannot support the plans the market needs. We build SaaS platforms designed to survive success.
Marketing Wise has delivered 22+ SaaS platforms since 2021 — B2B vertical tools, workflow platforms, client management products, and marketplace SaaS for founders and enterprise teams in Noida, Delhi, and Gurugram. Each product ships with multi-tenant data isolation, a billing engine that handles trials and plan changes, and an onboarding flow that activates users before they churn.
We approach SaaS architecture with the growth constraint in mind: the database schema, API design, and billing structure we choose at v1 must support 100× user growth without a rebuild. That means row-level security for multi-tenancy, idempotent webhook billing, and a modular feature architecture that lets you ship new plans without touching core infrastructure.

No mystery phases. Four gates every SaaS platform engagement crosses — from product definition to paying customers.
We map the full product: user roles, multi-tenant data model, feature scope, pricing plan structure, and integration requirements. Architecture is documented and signed off before build starts — the decisions made here determine whether the product can scale without a rebuild.
Authentication, team workspaces, multi-tenant database, subscription billing, and the user onboarding flow are built and tested. The product is live in a staging environment with real billing by the end of this phase.
The product's core workflow is built sprint by sprint. Third-party integrations are wired up. An internal admin panel and public API (if in scope) are delivered in this phase. Beta users are invited before the sprint closes.
Load testing, monitoring, alerting, and error tracking are configured. The onboarding flow is reviewed against beta user behaviour and refined. The product is handed over with runbooks, deployment docs, and a 30-day post-launch support window.
Reached 310 paying companies within 5 months of launch. Monthly churn held below 4% through month six.
The founder had validated demand for a simple, affordable HRMS alternative for SMEs. Previous build attempts had failed because the product was built without multi-tenancy or proper billing — each new customer required manual setup by the dev team.
We built a multi-tenant platform with company onboarding in under 5 minutes, role-based access (admin, manager, employee), automated leave approval workflows, attendance via QR code, and Razorpay subscription billing with a 14-day free trial.
Next.js, Node.js, PostgreSQL, Razorpay, AWS S3, Resend
Launched in 20 weeks. 180 law firms onboarded in the first 4 months. Average session length 34 minutes — a strong engagement signal.
Independent lawyers in India were managing client matters in WhatsApp, Excel, and paper files. The founder needed a product affordable for solo practitioners but capable for 10-person firms — with document management, deadline tracking, and client communication built in.
We built a multi-tenant SaaS with matter pipelines, document storage with version history, deadline reminders via WhatsApp and email, a client portal, and team collaboration features. Monthly billing at ₹999–₹2,999 per firm.
React, FastAPI, PostgreSQL, AWS S3, Razorpay, Twilio WhatsApp API, SendGrid
Sold to 14 enterprise clients in the first 6 months at ₹1.2–3.5L annual contract value. Replaced Excel-based tracking for all 14 clients.
The consultancy manually managed vendor compliance documents, audit schedules, and renewal reminders for enterprise clients using Excel and email. Scaling to more clients was blocked by the manual effort required per client.
We built a multi-tenant SaaS where each enterprise client has a workspace with a vendor directory, document upload with expiry tracking, automated renewal alerts, and audit checklists with sign-off workflows.

"They delivered our platform in 12 weeks, on budget and exactly to spec. Weekly demos kept us informed at every stage and the final product matched the requirements document line by line."
"The API architecture they designed handles our peak load without breaking a sweat. We have had zero downtime in eight months of production. The codebase is clean, documented, and our internal team can extend it independently."
"We evaluated three development agencies before choosing Marketing Wise. Their scoping process was the most rigorous — they produced a requirements document that found two gaps we had not identified ourselves."
"The backend they built scaled from 500 to 15,000 daily active users in six months without a single architecture change. That kind of headroom built into the design is rare from an agency engagement."
"Post-launch support was exceptional. They flagged and fixed two edge cases we had not anticipated within 24 hours. The handover package — source code, infra docs, runbook — meant our team could take ownership immediately."
