Custom Software Development Services for Modern Businesses
Web applications, mobile apps, enterprise platforms, and custom AI integrations — engineered by an ISO 27001 certified software development company in India. You own the code, the data, and the roadmap.
When custom software beats off-the-shelf SaaS
SaaS is the right answer when your workflow is generic. Custom is the right answer when the workflow is the differentiator. The honest test: would three competitors use the exact same tool, configured identically? If no — you need custom.
Off-the-shelf SaaS
- ✓ Fastest to start, lowest upfront cost
- ✓ Vendor handles updates and security
- ✕ Per-seat pricing scales painfully past ~50 users
- ✕ Your workflow has to fit their model
- ✕ Integrations cost extra and can break on vendor updates
- ✕ Your data lives in someone else's database
Custom Software (Proeffico)
- ✓ You own the source code, the data and the roadmap
- ✓ 30–60% lower TCO over 3 years past ~50 users
- ✓ Workflow shaped to your business, not the other way round
- ✓ AI, automation and integrations baked in from day one
- ✓ ISO 27001 secure-by-design
- ✓ Optional on-prem deployment — defence and BFSI ready
What we build
One delivery team, six capability lanes — used together or independently, on cloud, on-premise, or hybrid.
Custom Web Application Development
Production-grade web platforms engineered for scale — multi-tenant SaaS products, internal operations tools, customer portals, dealer/distributor portals and API-first marketplaces. Built on modern stacks (React, Next.js, Node, .NET, Python) with cloud-native architecture and ISO 27001 secure-by-design practices.
Cloud + DevSecOps stackAI Software Development & Custom AI Integrations
Embed AI where it changes the unit economics — document intelligence with LLMs, conversational copilots, computer-vision inspection, predictive analytics, and autonomous agents triggered by your business events. We integrate OpenAI, Anthropic Claude, Llama and on-prem private LLMs as part of the same delivery.
AI & ML capabilitiesEnterprise Software Development
Legacy modernisation, ERP/CRM customisation (ERPNext, Salesforce, Zoho, Dynamics), enterprise integration (ESB, iPaaS, webhooks, SAP, Tally), and complex workflow engines. Designed for compliance-bound industries — BFSI, manufacturing, healthcare, logistics — where downtime is not an option.
Process automationMobile App Development
React Native and Flutter cross-platform builds, plus native iOS / Android where performance demands it. Offline-first architecture, push + WhatsApp notification stacks, in-app payments (Razorpay, Stripe), and App Store / Play Store deployment — managed end-to-end.
Field-deployment case studiesAI Agents & Autonomous Operations
Beyond chatbots. We build agentic systems that read your data, decide and act — raising tickets, triggering workflows, calling APIs, sending WhatsApp / Slack updates. Use cases: lead qualification, inventory replenishment, customer-support triage, document processing, internal helpdesks.
AI agent integrationsUI / UX Engineering & Design Systems
User research, journey mapping, interactive prototypes in Figma, accessibility-compliant interfaces (WCAG 2.1 AA), and reusable design systems. Hand-off to engineering is friction-free because the same team builds both.
Industries we serve
Domain depth across regulated and operations-heavy sectors. We do not pretend to be everywhere — these are the verticals where our delivery is battle-tested.
Manufacturing
Shop-floor MES, OEE dashboards, predictive maintenance, vendor portals.
Retail & QSR
POS extensions, loyalty engines, in-store analytics, dealer-network portals.
Healthcare
HIPAA-aware patient apps, hospital workflow tools, telemedicine modules.
Logistics & SCM
Fleet visibility, last-mile apps, EV charging ops, warehouse digital twins.
BFSI
Compliance-grade portals, KYC pipelines, partner integrations, audit trails.
Education
LMS, admissions, mentor-student platforms, exam invigilation tools.
Technologies we use
Modern, multi-runtime, cloud-agnostic. We will recommend the stack that matches your operating model, not the one that sells the most consulting hours.
Our development lifecycle
A predictable rhythm. No surprise change requests. Weekly demo, fortnightly invoice, monthly steering.
Discovery & business case
Stakeholder interviews, problem framing, success metrics, risk register, build-vs-buy analysis.
Solution architecture
System blueprint, data model, integration map, security threat model, capacity sizing.
Agile delivery
2-week sprints, demo every Friday, fixed-cost or T&M, signed-off acceptance criteria.
Quality & security
Automated tests, SAST/DAST, dependency scans, manual QA, UAT, performance benchmarks.
Deployment
CI/CD, blue-green or canary release, runbooks, observability stack, on-call handover.
Hyper-care & evolve
30/60/90-day hyper-care, SLA-backed AMC, roadmap planning, continuous optimisation.
The economics — why finance teams approve custom software
Indicative ranges drawn from delivered engagements. We will validate against your scale in the scoping call.
Lower TCO vs licensed SaaS over 3 years (no per-seat lock-in).
Faster process throughput post-deployment for ops-heavy workflows.
Typical time-to-MVP for a mid-complexity custom platform.
Source-code ownership — your IP, your repository, your future.

Most enterprise software does not need a "rebuild for AI." It needs AI threaded in at the right seams — search, support, document handling, decisioning, and customer-facing copilots.
- Conversational copilots over your existing CRM / ERP / helpdesk.
- Document intelligence — invoice, contract, KYC, policy QA.
- Computer vision plug-ins via VIZO361 — PPE, footfall, intrusion.
- Agentic workflows: lead qualification, ticket triage, replenishment, payment follow-ups.
- On-prem private LLMs for sensitive sectors (defence, BFSI, healthcare).
On-prem LLM development
Run Llama, Mistral or fine-tuned models behind your firewall. We handle GPU sizing, vector store, RAG pipelines, observability, and the secure SDLC around them.

Frequently asked questions
Why choose custom software development over an off-the-shelf SaaS product?+
Off-the-shelf SaaS is the right answer when your process is generic. Custom software wins when your competitive advantage lives inside the workflow — your pricing model, your routing logic, your industry compliance rules, your data assets. Beyond ~50 users, per-seat SaaS often costs more than amortised custom over 3 years, and you stop owning your roadmap. We help you choose honestly: if SaaS is the right call, we'll say so.
How long does custom software development take?+
An MVP for a mid-complexity platform typically ships in 12–16 weeks with a 4–6 person team. A simple workflow tool can ship in 6–8 weeks. Enterprise-grade platforms with deep ERP/CRM integrations and compliance certification land in 6–9 months. We commit to a fixed scope sprint zero before any code is written.
How much does custom software development cost in India?+
Indicative ranges (₹, GST extra): ₹6–15 lakh for an MVP, ₹15–60 lakh for a full v1 platform, ₹60 lakh–2 Cr for enterprise-grade builds with integration and compliance scope. Pricing is fixed-cost per sprint or T&M depending on engagement style. Detailed estimate after a 60-minute scoping call.
Who owns the source code and IP?+
You do — 100%. The repository is in your GitHub / GitLab / Azure DevOps org from sprint zero. Proeffico has working access, not ownership. No usage royalties, no SaaS lock-in, no escrow drama.
Can you integrate AI into existing software we already own?+
Yes — that is one of our most common engagements. We add LLM-powered features (intelligent search, document QA, agentic workflows), computer-vision modules (PPE, footfall, intrusion), or predictive analytics on top of your existing platform via APIs. Typical integration spans 4–10 weeks.
Do you offer post-launch support and maintenance?+
Yes. Hyper-care is included for 30 / 60 / 90 days post-launch depending on engagement size. After that we offer AMC at 18–22% of dev cost per year, covering bug fixes, security patches, dependency upgrades and 99.5% uptime SLA. Roadmap evolution is contracted separately.
Are you ISO 27001 certified?+
Yes. Proeffico Solutions Pvt Ltd holds an active ISO 27001:2022 certificate, covering our entire development and operations lifecycle. Certificate and Statement of Applicability available on request to sales@proeffico.ai.
Which industries do you have the most experience in?+
Telecommunications and BFSI (largest engagements via Alten Calsoft / Omantel and partner work), manufacturing (MES, OEE, vendor portals), retail (POS, dealer networks, in-store analytics), healthcare and logistics. We do not work on gambling, adult content, or anything explicitly prohibited under Indian law.
