Project Specifications
Active ProtocolWhat We
Offer.
Starting a SaaS product can be overwhelming. We help you avoid common mistakes by building robust platforms using modern, proven technologies. Whether you need a subscription-based tool, multi-tenant system, or complex business software, we create solutions that are secure, fast, and easy to maintain.
Multi-Tenant Architecture
Complete multi-tenant architecture with strong data isolation
Payment Integration
Smooth payment integration (bKash, Nagad, SSLCommerz, international cards)
High Performance
High-performance systems that handle thousands of users without slowing down
The Engineering Engine
Quantifiable ROI
- Outcome 01Full control over your data
- Outcome 02Flexible pricing models (no per-user penalties)
- Outcome 03Blazing-fast performance for better user experience
How We Deliver
Domain Mapping
We design multi-tenant isolated databases and workflow blueprints.
Core Prototype
Delivering primary functional systems with secure user sessions.
Scale & Integrate
Connecting local MFS payment systems and deploying containerized cloud setups.
Who It's For & Engagement Boundaries
Clear expectations before you commit budget. We engineer systems for organizations where our technical architecture genuinely delivers ROI.
Who This Service Is Engineered For
- Tech startups, founders, and enterprises building multi-tenant subscription software products
- Businesses transitioning internal tools into commercial B2B SaaS platforms
- Platforms requiring automated recurring billing (bKash Tokenized Checkout, Stripe) and tenant data isolation
If you have not yet validated market demand or spoken to target customers, conduct customer discovery interviews before writing multi-tenant SaaS code.
What's Included vs. Handled Separately
Included in the Engagement:
- Multi-tenant database architecture with strict tenant isolation (PostgreSQL RLS or schema-per-tenant)
- Subscription billing webhooks, automated invoice generation, and plan upgrade/downgrade logic
- User authentication, role-based access, and tenant onboarding flows
- Cloud infrastructure Docker containerization and CI/CD pipelines
Handled Separately or Excluded:
- Customer support for your end-users (we support your technical team; you handle end-user customer service)
- Payment processor merchant account transaction fees and chargebacks
Production Multi-Tenant SaaS vs. Single-Tenant Clones
Why scalable multi-tenant architecture protects your margins.
| Evaluation Factor | Multi-Tenant SaaS Architecture | Single-Tenant Clones |
|---|---|---|
| Operational Overhead | Single codebase & database pool serves thousands of tenants efficiently | Requires deploying and maintaining separate servers for every new client |
| Feature Deployment | New features and bug fixes deploy instantly across all customers | Must manually update dozens of disparate client installations |
| Hosting Margins | Shared cloud resources maximize profitability as subscription count grows | Infrastructure costs scale linearly, eating into subscription margins |
| Data Isolation | Strict cryptographic and row-level tenant security enforced at database level | Higher maintenance risk during manual server configurations |

Frequently Asked Questions
Clear, transparent answers about our engineering process, pricing factors, deliverables, and code ownership.
Q1.What architecture do you use for multi-tenant SaaS platforms?
We implement secure multi-tenant architectures with strict tenant data isolation (using schema-per-tenant or row-level security in PostgreSQL), automated tenant provisioning, JWT session management, and scalable cloud microservices capable of handling millions of requests.
Q2.How do you handle subscription billing and local payments in Bangladesh?
We integrate automated recurring subscription webhooks using bKash Tokenized Checkout, Nagad PGW, SSLCommerz, and Stripe/PayPal for international clients, complete with automated invoice generation, failed payment retries, and access provisioning.
Q3.Who owns the SaaS intellectual property and user database?
You own 100% of the intellectual property, database records, and codebase. We hand over the complete repository and cloud credentials upon project delivery.
