Can you migrate our historical data from Tally, Busy, or Excel sheets?

Yes, absolutely. We specialize in zero-data-loss migration from Tally, Busy, Excel, or legacy local databases. We extract, clean, validate, and map all opening balances, customer records, vendor ledgers, inventory stock, and historical transactions before go-live.

Why build a custom ERP instead of subscribing to SAP Business One or Odoo?

Ready-made enterprise software forces rigid workflows on your business and charges expensive recurring per-user monthly subscription licenses that punish company growth. A custom ERP built by The Tab Theory matches your exact operational processes, integrates natively with Indian platforms (WhatsApp, GST portal, E-way bill), and gives you 100% source code ownership with zero user seat rent.

Is the ERP cloud-based, and can factory floor staff use it on mobile phones?

Yes. All our ERPs are cloud-native, secured with SSL, automated off-site backups, and role-based permissions. We also build React Native companion mobile apps for shop-floor supervisors, warehouse operators, and drivers that support offline caching for patchy internet environments.

Do we own 100% of the source code and database upon completion?

Yes. Upon project completion and handover, you receive complete intellectual property ownership, Git repository access, architecture documentation, and cloud server credentials. You are never locked into proprietary vendor subscriptions.

Core Modules

Bespoke ERP architecture, zero bloat.

Every module is custom-engineered to match your factory floor, supply chain, and back-office realities without forcing you into template limitations.

Multi-Godown Inventory & Stock

Real-time visibility across factories and regional godowns. Batch and serial tracking, barcode/QR scanner integration, low-stock threshold triggers, and inter-branch stock transfers.

Production Planning & BOM

Multi-level Bill of Materials (BOM), machine work-orders, scrap tracking, and stage-wise production tracking. Prevent bottlenecks and forecast raw material procurement accurately.

Accounts & GST E-Invoicing

Direct integration with the Indian GST portal for 1-click IRN e-invoicing and automated E-way bill generation. General ledgers, accounts receivable, and automated reconciliation reports.

FAQ

Custom ERP Development — Frequently Asked Questions

How much does custom ERP development cost in India?

We offer Dedicated Sprints at ₹1,800/hr (minimum 30 days / ~₹10,00,000+ commitment) for modular ERP builds, as well as full custom enterprise milestone delivery. For ad-hoc module updates or audits, we also provide on-demand consulting at ₹2,000/hr. You receive 100% source code ownership, zero per-user recurring fees, and free post-launch warranty support.

How long does a custom ERP project take to build?

A focused ERP (3–5 core modules like inventory, GST billing, and production) ships in 10–14 weeks. A full multi-plant enterprise suite typically takes 4–6 months. You receive weekly live demo builds throughout development so you see steady progress every week.

Can you migrate data from Tally, Busy, or legacy Excel software?

Yes. Zero-data-loss migration from Tally, Busy, Excel sheets, or older ERP systems is included in every project. We extract, clean, map, and verify opening balances, stock registers, and ledgers side-by-side with your accounting team before cutover.

Why build a custom ERP instead of subscribing to SAP or Odoo?

Ready-made ERPs charge per-user recurring seat fees forever and force your business to fit their rigid template. A custom ERP matches your exact manufacturing and distribution workflows, integrates with Indian channels (WhatsApp, GST portal), and you own the asset permanently.

Is the ERP cloud-based? Can staff access it on mobile phones?

Yes, every ERP we build is cloud-native — accessible securely from factory, warehouse, office, or phone. We also develop dedicated React Native companion mobile apps for shop-floor supervisors, delivery teams, and field executives with offline caching capabilities.

Do we receive full source code ownership upon completion?

Yes, 100%. Upon project completion, we transfer complete intellectual property rights, Git repositories, architectural documentation, and cloud server access to your organization. No vendor lock-in.
