How to start
Tell us what you need in your own words. You talk to the developers who would build it and get a written, line-item estimate.
Get a project estimateWhen spreadsheets and Tally stop being enough
Many businesses we meet run on TallyPrime for accounts, Excel for production plans and stock, and WhatsApp for approvals. It works until volumes grow or a second plant or godown opens.
A custom ERP replaces the spreadsheets, not necessarily the accounts. We model your items, units, locations and approval chains as they are, then roll out one module at a time.
Challenges
Operational gaps an ERP closes
Stock figures that never agree
Physical stock, Tally and the production sheet each show a different number.
Job work that is hard to trace
Material sent to job workers and returned with process losses is difficult to match against challans.
Re-keyed GST documents
Invoices and e-way bills typed in separate places invite mismatches.
Approvals stuck in chats
Purchase requests and price exceptions approved on WhatsApp leave no audit trail.

How it works
How work moves through your ERP, from purchase to dispatch
Each department updates the same records, so stock, costs and GST documents always agree.
- Purchase and stores
Step 1: Purchase and receipt
An indent becomes a purchase order; goods are received against it with a GRN and matched to the supplier's bill.
- Stores
Step 2: Stock updated by location
Received items move into the right godown, batch and unit, so stock is correct before anyone plans production.
- Shop floor
Step 3: Production
Work orders issue materials from the bill of materials, and output and rejections are entered from a tablet at the line.
- Sales team
Step 4: Sales order and dispatch
A sales order checks price lists and credit limits, then moves to packing and dispatch with scanned items.
- Billing
Step 5: GST documents
The e-invoice IRN, signed QR code and e-way bill are generated from the same screen, with no re-typing.
- Accounts and management
Step 6: Accounts and MIS
Vouchers sync to your accounting software, and management sees daily sales, stock value and receivables.

Plain-English glossary
ERP terms, in plain English
- Bill of materials (BOM)
- The recipe for a product: every raw material and sub-assembly, with quantities. The ERP uses it to issue materials and work out the cost of each work order.
- GRN (goods received note)
- The record made when goods arrive from a supplier. Matching it to the purchase order and the bill before payment stops you paying for goods that never came.
- Job work
- Sending material to an outside processor, for example for plating or machining, and receiving it back. The ERP tracks quantities out and in, including process loss, against each challan.
- E-invoice (IRN)
- An invoice registered on the government's portal, which returns an Invoice Reference Number and a signed QR code. Generating it inside the ERP avoids typing invoices twice.
- MIS (management information system)
- Daily or weekly summaries such as sales, stock value and receivables that owners use to make decisions without waiting for month-end accounts.
Product preview
Purchase desk, shop floor tablet, dispatch and daily MIS
Purchase and stores. Stores and purchase teams see what is on order, what has arrived and where a bill does not match, before any payment is made. 
Shop floor. Supervisors enter output and rejections at the line on a tablet, so stock and costing update in the same shift. 
Sales and dispatch. Each sales order moves from packing to e-invoice and e-way bill in one flow, with the IRN and QR code printed on the invoice. 
Management. Owners see sales, stock value, receivables and production efficiency every morning instead of waiting for month-end reports.

Modules in the first phase
Purchase and inventory alone is far smaller than purchase, production, sales and MIS together.
Workflows and approvals
Multi-level approvals, customer pricing and job work add rules to test.
Integrations
Two-way Tally sync, GST APIs and hardware each carry their own effort.
Sites, godowns and GSTINs
Several companies or states mean more configuration, numbering series and testing.
Migration and parallel run
Opening balances, open orders and item masters must be cleaned and verified.
Estimates are written from your scope, with the effort and assumptions behind each line item.

FAQ
Frequently asked questions
Do we have to replace Tally to use a custom ERP?
No. Many clients keep TallyPrime as the books of account while the ERP handles operations: purchase, stock, production, sales orders and dispatch. Ledgers, items and vouchers sync through Tally's XML interface, on a schedule or when a document is approved. Your accountant keeps working in a familiar tool and auditors see the same books.
How are GST e-invoices and e-way bills handled?
When a sales invoice is approved, the ERP sends it to the Invoice Registration Portal through a GST Suvidha Provider, receives the IRN and signed QR code, and prints them on the invoice. E-way bills are generated from the same data, with transporter and vehicle details added at dispatch. Your GST consultant should confirm HSN codes and applicability for your business.
Should we implement Odoo, ERPNext or SAP Business One instead?
If your processes are close to their standard flows, a configured platform is often faster to launch. A custom ERP makes sense when the core of your operations, such as job work across several processors, made-to-order costing or distributor schemes, would need heavy customisation that makes upgrades painful, or when licence costs across many users outweigh a build. We can also build custom modules around an existing ERP.
How long does an ERP project typically take?
The first module, often purchase and inventory, typically goes live in three to five months including data preparation and a parallel run. A full ERP covering production, sales, dispatch and MIS usually rolls out over six to twelve months in planned phases. Master data quality and the number of sites going live together are the biggest variables.
