Level 4 · Enterprise engagement

At this scale, we don't start with a quote. We start with discovery.

Enterprise systems fail on assumptions, not on code. So the first thing we sell is not development — it is a paid discovery phase that produces a specification, an architecture and a defensible number. Everything after that is priced against a document you own.

Why this tier is different

Three honest reasons we won't quote a fixed price on day one.

The scope is genuinely unknown

An enterprise system touches departments that have never written their process down. Until we have mapped them, any number we give you is a guess dressed up as a quotation — and guesses get renegotiated.

Integration risk dominates

The cost driver is rarely your new system. It is the eleven-year-old ERP it must talk to, the data nobody has cleaned, and the compliance rule discovered in month four. Discovery finds those first.

Architecture decisions are expensive to reverse

Multi-tenancy, data residency, high availability and audit requirements shape every layer. Choosing them properly before writing code is far cheaper than retrofitting them afterwards.

What you get from discovery, even if you never build with us

A business analysis, a technical specification, a data and integration architecture, a security and infrastructure plan, a phased delivery roadmap and a detailed cost model. It is your document. You can tender it to anyone — including us.

Engagement model

How an enterprise project actually runs.

Five phases. Each ends with something you can review, approve or walk away from.

01

Discovery & architecture

Business analysis across every affected department, process mapping, data architecture, integration architecture, security and compliance requirements, scalability planning and a detailed technical specification.

Duration4 – 10 weeks
Cost₹75,000 – ₹2,00,000+
OutcomeA specification you own
02

Design & foundation

Complete design system and UX for every role, database and API architecture, environment provisioning, CI/CD pipeline, authentication and permission framework. Nothing user-facing ships yet — this is the floor everything else stands on.

Module delivery

Built and released module by module, each one demonstrable on staging. You see working software every two to three weeks rather than a single reveal at the end.

04

UAT, migration & training

Your teams test against the approved specification on a production-like environment with migrated data. Training runs department by department, and the operations runbook is handed over.

Go-live & hypercare

Cutover with a rehearsed rollback plan, then a defined hypercare window with priority response before the engagement moves to a standing support arrangement.

Capability

What "enterprise" adds on top of the Advanced tier.

Everything in the Advanced Web Application package is assumed. These are the capabilities that only appear at enterprise scale — and each one is a real cost line, not a bullet point.

Architecture

  • Multi-tenant architecture with strict data isolation
  • High availability across zones
  • Disaster recovery with defined RPO and RTO
  • Service decomposition where it earns its complexity
  • Event-driven processing and message brokers
  • Read replicas and reporting databases
  • Data partitioning for high-volume tables

Security & compliance

  • Single sign-on against your identity provider
  • Enterprise two-factor and session policy
  • Complete audit systems with immutable trails
  • Advanced permission models to field level
  • Data residency and retention controls
  • Encryption at rest and in transit, key rotation
  • Independent security audit and penetration testing

Data & integration

  • Large-scale migration from legacy systems
  • Data cleaning, transformation and validation
  • Reconciliation and rollback for every migration run
  • Integration with ERP, HRMS, accounting and banking
  • Master data management
  • Reporting and BI layer

Infrastructure & operations

  • Dedicated environments per client
  • Infrastructure as code
  • Container orchestration and autoscaling
  • Full observability — metrics, traces, logs
  • Automated testing across the pipeline
  • Blue/green or canary deployment
  • Verified backups and restore drills
  • Defined incident response and on-call

How the money is structured.

Discovery is invoiced and completed before the development contract is signed, so you commit to the large number only once you have the specification in hand.

Terms

What you own, and what stays ours.

You own

  • The project source code, in full, after final payment
  • The discovery specification and architecture documents
  • The domain, hosting, cloud and database accounts
  • Payment gateway, WhatsApp, email and API accounts
  • All your data, exportable at any time
  • System documentation and runbooks

Sunarcode retains

  • Internal tools and reusable frameworks
  • Internal libraries and generic components
  • Internal deployment scripts
  • Proprietary systems developed outside this project

Unless otherwise agreed in writing. None of it is required for you to run, modify or hand your system to another team.

Scope Control — on every enterprise quotation

The quoted price is based on the features and requirements explicitly described in the approved scope. Any feature, integration, workflow, page, design revision, functionality or technical requirement not included in the approved scope is treated as a Change Request and may result in additional charges and timeline changes. At enterprise scale, the discovery specification is the approved scope — which is precisely why it is worth paying to get right.

Start with a conversation, not a quotation.

Tell us what the system has to do and which departments it touches. We will tell you honestly whether you need enterprise discovery, or whether the Advanced tier already covers it.
