Custom ERP software development
An ERP doesn't have to be the all-at-once, change-freeze, board-meeting project everyone has nightmares about. We build them module by module, starting with the workflow that's actually broken today. The master data model that might be useful someday can wait.
What's included in ERP development.
Most engagements start the same way: inventory reconciliation that doesn't tie, a GST invoice that took an accountant 40 minutes, or a purchase order approval flow that lives in WhatsApp. We pick one, sit with the people who run it, and write down every step, exception, and approval until the scope is agreed in writing. Only then do we design and build it. The next module follows once the first is live and in daily use.
Distributors, manufacturers, and trading houses doing ₹5–500 cr revenue who have outgrown Tally or off-the-shelf accounting tools but are not big enough to need SAP B1. Especially good when you already have a Tally instance and want to keep it as the system of record for one part of the business while we modernize the rest.
- 01
Inventory + warehousing
Multi-location stock, batch and serial tracking, reorder points, cycle-count reconciliation, and a stock-ageing report that explains the variance between physical and book stock.
- 02
Purchase + procurement
Indents, RFQ, vendor scoring, PO approval chains, GRN with QC routing, and three-way matching against the invoice before payment goes out.
- 03
Accounting + GST
Double-entry ledger, GST-ready invoices and credit notes, GSTR-1 and GSTR-3B exports, TDS deduction at source, and a reconciliation view that ties to Tally when needed.
- 04
Manufacturing (light)
BOMs, work orders, routing, WIP tracking, and consumption posting. A fit for SMBs with one or two factories. It does not replace SAP at a 500-crore plant.
- 05
HR + payroll
Employee master, attendance integration, leave engine, payroll heads with PF/PT/TDS, payslip generation, and Form 16 prep. Self-service portal for the rest.
- 06
Reports + finance close
Trial balance, P&L, balance sheet, ageing reports, sales registers, and a finance close checklist that owners can sign off on monthly without an Excel marathon.
From one broken process to a working ERP module.
Pick the broken process
We start with the workflow that hurts most today, whether stock that will not reconcile or purchase approvals chased on WhatsApp. We sit with the people who run it and write down every step, document, exception and approval until the module scope is agreed in writing.
Build one module
We design the masters, screens and posting rules for that module alone, and connect it to Tally or GSTN where the agreed scope calls for it. Finance and operations review each screen against the requirement document before any live data is moved across.
Cut over, then extend
We load masters and open balances, reconcile them against your existing books, and train each department on its own screens. Once the module is in daily use, we run the same study for the next one, so the ERP grows in the order your business needs.
Questions about ERP development.
- Where should an SME start when moving from spreadsheets to an ERP?
- With the one process that is broken today, before any work on the full master data model. That is usually stock that does not reconcile, a GST invoice that takes an accountant 40 minutes, or a purchase order approval that lives in WhatsApp. We digitize that one module first, and the next follows once the first is live and in daily use. We have built ERP systems for a multi-office law firm and for Bollard, an acoustic ceiling manufacturer.
- Does a custom ERP replace Tally, or can we keep using it?
- You can keep it. Tally can stay the system of record for accounts while we modernize inventory, purchase, and sales around it. Our accounting module produces GST-ready invoices, GSTR-1 and GSTR-3B exports, and a reconciliation view that ties back to Tally when needed. If you already use GSTN APIs or SAP Business One, we map those connections during the requirement study so nothing is keyed in twice.
- How is ERP scope agreed, and what if our requirements change mid-project?
- Each module starts with a requirement study. We sit with the people who run the process and write down every step, exception, and approval until the scope is agreed in writing. Only then do we design and build, and the timeline and cost are quoted against that scope. If something new comes up, we write it up as a change, agree its effect with you, and then build it, so nothing is added silently.
- How do you move our existing data into the new ERP and train staff?
- We migrate masters and open balances in passes: a sample load your team checks, a validation pass for duplicates and broken references, a rehearsal, then the go-live cutover, with finance signing off a reconciliation against the old books. Each department is trained on the screens it uses. After go-live we stay on for support, and new modules and changes continue under a maintenance retainer.
Requirements First: Why We Map Every Workflow Before We Build
Most business software projects go wrong before any code is written. Here is how we map the paper, spreadsheet, and WhatsApp process first, agree the scope in writing, and only then build.
ERPTally vs ERP: Is Tally an ERP, and How to Tell You Have Outgrown It
Tally is very good at the books. The trouble starts when sales, dispatch, and production run on WhatsApp screenshots and Excel registers around it. Here is how to tell which side of that line your business is on.
