ERP System Architecture: Core Modules, Functional Workflow, and Cost Breakdown

With this digital-first economy, one cannot manage every task of the business, say, inventory, HR, finance, CRM, relying on mere spreadsheets or disjointed software. ERP software development services, in this respect, work as the big game-changers and provide the companies with an integrated, intelligent, and real-time operational management solution under one digital roof.

ERP system architecture, its core modules, working, and costs heavily influence any business decision-making. Be it a growing enterprise or an established firm looking for workflow automation, having a basic understanding can allow you to make an informed investment. Delve into how Litost India builds a robust ERP system tailor-fit to your business DNA.

What Is ERP System Architecture?

At the very core, ERP architecture is the technical design that describes the manner in which the various components — modules, databases, user interfaces, and integrations — interact to present a single system.

Think of it as the building plan of your business’s digital headquarters.

Three Primary Layers of ERP Architecture:

. Presentation Layer: The front-end interface your users interact with — dashboards, forms, analytics, etc.

. Application Layer: This is the logic center where modules process business rules and handle data transactions.

. Database Layer: The foundation where all business data — inventory, customer info, invoices, reports — is stored and managed securely.

At Litost India, ERP architecture is designed for scalability, data integrity, cross-platform accessibility, and customization, ensuring your system evolves as your business grows.

Core Modules in ERP Software Development

The best ERP systems are equipped with customizable modules that interface with specific business functions. Litost India never creates prepackaged solutions for its clients; instead, it develops flexible ERP solutions tailored to your industry and workflow.

Functional Workflow: How It All Comes Together

The magic of an excellent ERP system is integration. Instead of hopping from software to software for each department, the team accesses it all from one dashboard. Let's see an example of its functioning:

A sales team closes a deal → data flows to inventory to reserve products → finance generates an invoice → delivery schedules the dispatch → HR calculates commissions → management gets real-time analytics on performance.

With Litost India’s ERP solutions:

. Manual errors are minimized

. Time is saved

. Customer satisfaction improves

. Business decisions become data-driven

Every workflow is mapped to your real-world processes, creating an efficient, seamless, and intuitive operational flow.

Cost Breakdown: What to Expect

One of the most common questions business owners ask is — How much will an ERP system cost me?

The truth is, ERP development costs vary based on several factors:

Key Cost Factors:

. Number of Users: More users = more licenses and support

. Modules Required: A full-suite ERP costs more than a basic version

. Customization Level: Tailored features take time and development

. Integration Needs: Connecting with third-party apps like Tally, SAP, or CRMs adds cost

. Hosting Preference: On-premise (your servers) vs. Cloud (SaaS-based)

Estimated Price Ranges:

. Basic ERP for SMEs: ₹1,50,000 – ₹4,00,000

. Mid-level ERP with 4–6 Modules: ₹5,00,000 – ₹9,00,000

. Advanced, Enterprise ERP with Full Customization: ₹10,00,000+

Litost India provides modular pricing, meaning you only pay for the features you need. There's also AMC (Annual Maintenance Contract) and post-deployment support included in plans.
