ERP Development in Rohini: Modules, Architecture and Data Decisions
An ERP is a set of connected modules, such as inventory, finance, HR and sales, that share one database so every fact is entered once. Before development starts, decide which module goes first, how it connects to your existing accounts and tools, where it is hosted and how personal data is protected. Mindrops builds custom, modular ERP from Pitampura.
Key takeaways
- List the steps that start from a re-typed document, need an approval, use an unusual calculation or feed a required report: that list is your real custom scope.
- The DPDP security rule takes effect in May 2027. Masking, access control, logs and backups are cheaper to design in than to add later.
- Define the eight or ten numbers you check before dashboards are designed, because a report can only use fields the data model holds.
- Keeping your current accounting package in phase one and exchanging data with the ERP is a valid choice.

ERP development in Rohini usually starts with a practical complaint: the stock register, the invoice book and the salary sheet each tell a slightly different story. Before you shortlist a developer, it helps to know what an ERP is made of, because the decisions that matter most are the same in every sector of Rohini: which modules to build, how they share data, where the system runs and how personal data is protected.
This guide covers those technical decisions. For what to build first by type of business, and how GST e-invoicing and e-way bills shape the design, read the companion guide on ERP development in Pitampura. The two are meant to be read together.
A short note on Rohini
As of October 2026, Wikipedia describes Rohini as a sub-city in North West Delhi, developed from the 1980s as a Delhi Development Authority project for "a composite society for all income groups". It lists three Red Line stations in Rohini: Rohini East, Rohini West and Rithala. Netaji Subhash Place, where Mindrops has its office, is an interchange station on the same Red Line.
Nothing in an ERP design depends on the postcode. What a nearby partner changes is how easy it is to sit with your team and watch how work really moves between the counter, the godown and the accounts desk. Treat that as a convenience, not a qualification.
Tailored ERP modules: what each one holds
An ERP is a set of modules that share one database. The point is that each fact is entered once: a sales order reserves stock, raises a purchase request when stock runs short, and later becomes an invoice and a ledger entry, without anyone typing it again.
| Module | What it holds | Usually connects to |
|---|---|---|
| Inventory and supply chain | Items, units, warehouses or godowns, stock movements, purchase orders, goods receipts | Sales (reservations), finance (stock value, payables), production (material issue) |
| Finance and accounting | Ledgers, invoices, payments, receivables and payables, approvals | Every other module posts into it |
| Human resources | Employee records, attendance, leave, payroll inputs | Finance (salary payables), projects (time) |
| CRM and sales | Leads, quotes, customers, sales orders | Inventory (availability), finance (invoicing) |
| Manufacturing and production | Bills of materials, production orders, material issues, finished goods | Inventory, purchasing, costing |
| Projects and tasks | Projects, tasks, timesheets, milestones | HR (time), finance (billing), CRM (won deals) |
You rarely need all six on day one. Start with the module whose errors cost you most; the rest can follow, because the shared records (items, parties, locations, users) are designed once. That master-data design is the part that is expensive to change later. Settle how you identify an item, how you record a customer so duplicates are caught, and which units you stock and sell in before any screen is built.
Industry-specific workflows: finding your exceptions
The standard modules cover the ordinary cycle of buying, storing, selling and paying. What differs by industry is a handful of workflows, and those are where custom development earns its cost. To find yours, list the steps that:
- start from a paper or PDF document that someone re-types today;
- need an approval, and note who approves and up to what value;
- use a calculation that packaged software does not do your way, such as slab pricing, scheme discounts or job-work charges;
- produce a report that a customer, auditor or the tax portal asks you for.
Whatever survives that list is your real scope. The Pitampura guide walks through typical priorities for shops, distributors, small manufacturers and service firms.
Scalable and secure architecture
These are the design choices to ask about, with the reason each matters.
- One database as the source of truth. Stock and ledger changes should be saved together in one transaction. If an invoice posts but the stock deduction fails, the books and the shelf disagree. Mindrops' ERP service lists PostgreSQL for this.
- Roles and scopes. Users should see only what their job needs: their own records, their team's or everyone's, per module. In the anonymised service agency ERP case study, access is set as own, team or all per module.
- An audit trail. Every financial or stock edit should record who changed what and when. It settles most internal disputes quickly.
- An API behind every screen. If the screens use the same documented API that integrations use, a connected tool never needs a back door.
- Background jobs for heavy and recurring work. Reminders, scheduled invoice drafts and overdue checks should run off a queue instead of slowing down the people entering data.
On technology, Mindrops' ERP service lists Node.js, Python, .NET and Java for the back end, PostgreSQL for data, and React 19 with TypeScript or Next.js for the interface. The case study above used React 18, TypeScript, Node and Express with tRPC, and PostgreSQL through Prisma. Our view is that the stack matters less than whether someone can maintain it in five years, so prefer mainstream tools and insist on written documentation.
Data protection: what the DPDP Rules mean for an ERP
An ERP holds personal data almost by default: employee records in HR, customer contact details in sales. India's Digital Personal Data Protection Rules, 2025 were published in the Gazette on 13 November 2025. Under Rule 1, a few administrative rules took effect at once, the consent-manager rule follows after one year, and the rest, including the security rule, takes effect eighteen months after publication. That works out to May 2027, so as of October 2026 those obligations are not yet in force, but ERP design has a long lead time.
Rule 6 sets out the reasonable security safeguards a data fiduciary (the business that decides why and how personal data is processed) must take. At the minimum they include:
- securing personal data through encryption, obfuscation, masking or virtual tokens;
- controls on access to the computer systems that hold it;
- logs, monitoring and review, so unauthorised access can be detected and investigated;
- backups, so processing can continue after a loss or compromise;
- keeping those logs and the relevant personal data for one year, unless another law requires otherwise;
- security terms in the contract with any data processor, such as a vendor that hosts or maintains the system.
The Press Information Bureau's explainer adds that failing to maintain reasonable security safeguards can attract a penalty of up to ₹250 crore under the Act. In ERP terms, these rules point to features you can ask for now: role-based access, masked fields (for example, hiding salary data from most users), access logs, tested backups and a retention policy. Whether the law applies to your business, and how, is a question for your legal adviser. This section is a design checklist, not legal advice.
Cloud-based or on-premise ERP
Where the ERP runs changes who does the maintenance work.
| Cloud-hosted | On your own server | |
|---|---|---|
| Access | From any branch or from home, over the internet | On your local network; remote access needs extra setup |
| Hardware | Provider's, billed as a recurring hosting cost | Yours: server, power, cooling, replacement |
| Backups and patches | Agreed with the host; you still need to test a restore | Your responsibility, or your IT vendor's |
| If the internet fails | System is unreachable unless an offline mode exists | Local users keep working |
Ask three questions: how many locations need access, how reliable is connectivity at each, and who restores the system after a failure. Mindrops' ERP service lists AWS and Azure with Docker and CI/CD as its cloud tooling. If you need an on-premise installation, say so at the start so it can be scoped properly.
Business intelligence and reporting
Decide the eight or ten numbers you actually check before anyone designs a dashboard. Typical candidates are receivables by age, stock by location, slow-moving items, margin by item and by customer, sales against target and purchases still pending delivery.
Reports depend on the data model. If items carry no category, you cannot report by category, so list the report you want and make sure the field exists. Heavy reports, such as a year of sales by customer, are often run against a separate read copy of the data so that month-end reporting does not slow down billing. Mindrops' ERP service describes dashboards and reporting layers over a single source of truth; see our BI dashboards service for the reporting side on its own.
Connecting to Tally, spreadsheets and other tools
Most businesses do not start from a blank page. They have accounts in Tally and years of spreadsheets. As of October 2026, TallyHelp documents integration with TallyPrime using JSON, XML and ODBC, plus file-based or database-level import and export, and says its APIs, HTTP or DLL methods can be used to sync Tally with CRMs, ERPs or hardware devices. In practice that gives you options:
- Keep your accounting package at first. Build inventory, sales or projects, and exchange data with the accounts you already trust. Move accounting into the ERP later, once the first modules are stable.
- Treat spreadsheets as a migration source. Agree import templates with validation rules, fix duplicates and missing fields before loading, and reconcile opening balances against your books.
- Insist on documented APIs and webhooks. They are what make future payment, logistics or e-commerce connections routine. Our API integration service covers this work.
Questions to ask about the architecture before you sign
- Can we export all of our data in a standard format (CSV, JSON or a database dump) at any time?
- Which actions are written to the audit log, and who can read it?
- Can a user be limited to one branch, warehouse or company?
- How are personal data protected: encryption, masking, access logs, backups, and how often is a restore tested?
- Who hosts the system, who applies patches, and how are upgrades tested before they reach us?
- Is every module available through a documented API?
- Will our own staff test with real data before go-live?

Conclusion
A good ERP is a small number of connected modules on one trustworthy database, with access controls and logs from the first release, an honest hosting decision and reports defined before the screens. Settle those, and the choice of developer becomes much easier to judge.
