Custom Software Development Engineering & Solutions in Bangladesh & Worldwide
Custom Software Development for Operational Workflows
Software engineered to match your operational processes, with full source code ownership and milestone-based delivery.
Project Specifications
Active ProtocolWhat We
Offer.
When commercial off-the-shelf software cannot accommodate your approval hierarchies, calculation rules, or multi-branch data, custom engineering gives you a system built specifically for your team. We build internal operating tools, client portals, and integrated database systems that replace spreadsheet clutter with reliable, automated workflows.
Tailored Business Logic
Designed around your exact operational workflows, approval hierarchies, and calculation rules.
100% Source Code Ownership
You own full repository rights, database schemas, and intellectual property without per-seat licenses.
Modular Architecture
Clean TypeScript and Node.js microservices designed to scale smoothly as transaction volumes grow.
Seamless System Integrations
Built-in APIs connecting local MFS gateways, accounting suites, legacy databases, and third-party tools.
The Engineering Engine
Quantifiable ROI
- Outcome 01Zero recurring per-user licensing fees as your organization scales
- Outcome 02Elimination of manual operational bottlenecks and spreadsheet errors
- Outcome 03Complete data sovereignty with self-hosted or private cloud options
- Outcome 04Structured post-handover testing and warranty coverage defined per Statement of Work
How We Deliver
Domain Blueprinting
Deep-dive workshops to map operational bottlenecks, entity models, and business logic.
Iterative Sprint Slices
Delivering functional milestones with live staging environments for continuous review.
Hardening & Handover
Load testing, security audits, staff training, and full source code handover.
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
- Organizations with custom calculation rules, multi-level approval hierarchies, or specific industry workflows
- Businesses managing disconnected spreadsheets for daily inventory, order approvals, or patient/client records
- Companies looking to avoid perpetual per-user monthly subscription fees as their staff headcount grows
- Teams requiring full source code ownership and complete control over database hosting and customer data
If your operational needs are standard—such as basic retail sales, double-entry bookkeeping, or a corporate brochure website—an off-the-shelf tool like QuickBooks or a standard CMS is faster to launch and much less expensive than custom software.
What's Included vs. Handled Separately
Included in the Engagement:
- Requirements scoping, technical architecture, and relational database design (PostgreSQL or MySQL)
- Responsive web interfaces with role-based access control and granular staff permissions
- Direct API integrations with local payment gateways (bKash, Nagad), SMS gateways, and internal systems
- Staging server reviews, automated testing, and deployment to your production environment
- Complete handover of source code, database structures, and deployment documentation upon project settlement
Handled Separately or Excluded:
- Cloud hosting accounts (AWS, Hostinger, DigitalOcean), which remain under your organization's direct ownership
- SMS gateway credits and merchant payment gateway transaction fees
- Physical hardware supply (thermal barcode printers, biometric scanners, or local servers)
Custom Software vs. Off-the-Shelf SaaS
Understand the strategic and financial trade-offs before committing your budget.
| Evaluation Factor | Custom Software (Vivago) | Off-the-Shelf SaaS |
|---|---|---|
| Code & IP Ownership | 100% owned by your company; full repository handover | Rented indefinitely; zero ownership or export rights |
| Cost as Team Scales | Flat development cost; unlimited users without per-seat fees | Costs multiply with every new employee or branch |
| Workflow Alignment | Engineered around your exact operational rules and approval paths | Forces your team to adapt to the vendor's rigid workflow |
| Integration Freedom | Direct integration with any local Bangladeshi MFS, SMS, or ERP API | Limited to pre-built marketplace integrations |
| Data Sovereignty | Hosted on your own private cloud or local on-premise server | Stored on vendor multi-tenant servers with shared risk |

Frequently Asked Questions
Clear, transparent answers about our engineering process, pricing factors, deliverables, and code ownership.
Q1.Who is custom software development suitable for?
Custom software development is ideal for businesses that have outgrown Excel spreadsheets or off-the-shelf SaaS tools with rigid limitations. If your operational processes give you a competitive advantage, or if generic software charges unsustainable per-user monthly fees, custom software gives you a proprietary system built around your exact business rules.
Q2.What factors affect the cost of custom software development?
The primary cost drivers are workflow complexity (simple data entry vs. multi-stage approvals), integration requirements (bKash/Nagad, legacy databases, SMS gateways), data migration volume, and security/compliance standards. We provide transparent, fixed-price milestone quotes after our initial technical scoping session.
Q3.Who owns the source code and intellectual property?
You do. Vivago Technologies operates with 100% intellectual property transparency. Upon completion and final milestone settlement, the complete source code, database schemas, and infrastructure configurations are transferred entirely to your organization without any proprietary lock-in.
Q4.What happens after launch? Does Vivago provide warranty and support?
Yes. Our delivery framework includes a structured User Acceptance Testing (UAT) phase prior to final handover, bug warranty coverage for delivered code, and optional ongoing SLA maintenance agreements for continuous technical support.
Q5.Can Vivago maintain or refactor an existing software system built by another team?
Yes. We regularly conduct codebase audits for companies whose previous development teams were unable to scale their software. We audit code health, database indexes, and security vulnerabilities before proposing an incremental refactoring or modernization plan.
