®Custom ERP & operations software
Businesses that outgrew spreadsheets and off-the-shelf tools. We build the operating system their actual workflow needs: inventory, billing, dispatch, and reporting in one connected place.
ERP & Operations at Nowgray
A custom ERP is a single system that runs the parts of a business that normally live in separate places: stock, purchasing, production, dispatch, invoicing and the reports built on top of them. Off-the-shelf ERPs assume a standard process and ask you to adopt it. A custom one starts from the process you already have and removes the re-entry between steps.
Most businesses do not arrive here because they want software. They arrive because a number stopped being trustworthy. Stock on the sheet does not match stock in the godown. Two people edited the same file. A dispatch went out against an invoice that was later revised. Once the numbers cannot be trusted, every decision slows down while somebody checks them by hand.
The honest answer is not always a custom build. If a business runs a common process with light customisation, Tally plus a well-chosen add-on is cheaper and faster. Custom ERP earns its cost when the workflow is genuinely specific, when several disconnected systems have to behave as one, or when the business has already outgrown two generic tools in a row.
We build these incrementally rather than as a single switchover. The first release usually covers the one process causing the most pain, runs alongside the existing method for a few weeks, and only replaces it once the numbers reconcile. That sequencing matters more than any feature list, because an ERP that people quietly stop using is worse than the spreadsheets it replaced.
What usually brings people here
The same data typed three times
An order gets entered in a sheet, again in the billing tool, and again in the courier panel. Every re-entry is a chance to introduce an error nobody catches until month end.
Stock nobody trusts
Physical stock and recorded stock drift apart, so purchase decisions get made on instinct. The fix is usually transaction-level movement records, not a better spreadsheet.
Reports that arrive too late to act on
Numbers assembled by hand on the 8th of the month describe a month you can no longer change.
Knowledge living in one person's head
One employee knows which sheet is authoritative and how the pricing exception works. That is a real operational risk, and it is the thing a system encodes best.
What we build
- Inventory and stock movement with batch, serial and multi-location tracking
- Purchase and vendor workflows with approvals and goods-receipt matching
- Order to dispatch to invoice, with GST-compliant billing
- Production and job-work tracking for manufacturing operations
- Role-based access with an audit trail on every change
- Tally, accounting and courier integrations so data moves without retyping
- Owner reporting built on the same live data, not a separate export

Common questions.
- Buy, if your process is close to standard. A generic ERP plus configuration is cheaper and faster to live. Build, if your workflow is genuinely specific, if several systems have to behave as one, or if you have already outgrown two off-the-shelf tools. We will tell you plainly which case you are in, including when the answer is that you do not need us.
- Yes, and that is the common arrangement. Accountants keep working in Tally while operations run in the ERP, with masters, invoices and ledgers syncing between them. Replacing an accounting system people already know is rarely worth the disruption.
- The first working module is typically 6 to 10 weeks, covering whichever process hurts most. Full replacement of a spreadsheet estate usually runs 4 to 8 months, released in stages. We deliberately avoid single-switchover launches.
- It gets migrated. Item masters, customers, vendors, opening stock and historical transactions are imported and reconciled against your existing records before anything goes live. Reconciliation is part of the project, not an afterthought.
- Yes. Code and IP transfer to you, and you can take it to another team whenever you want. We would rather earn the next phase than hold your operations hostage.
