ERP for businesses that have outgrown spreadsheets
When inventory lives in one spreadsheet, purchases in another and accounts in a third, nobody has the full picture. A custom ERP brings it all into one system with real-time data, role-based access and reports that update automatically.
I build ERPs for businesses that are too small for SAP but too complex for off-the-shelf tools.
Modules I build
Inventory management with stock alerts, batch tracking and multi-location support. Purchase order management with supplier tracking and approval workflows. Sales order processing with invoicing and payment tracking. Production planning with stage-wise tracking and labour allocation.
Financial dashboards with receivables, payables and cash flow. All modules share data so a sale automatically updates inventory and accounting.
Implementation approach
Start with the module that causes the most pain - usually inventory or sales. Get it working, get the team using it, then add modules incrementally.
Each module ships with training documentation and a walkthrough session so adoption is smooth.
Hiring a freelance ERP developer
ERP is the longest project on this list, so the fair question when hiring one person is continuity: what happens if they disappear halfway through inventory and purchasing. That risk is real and worth planning for rather than waving away.
The answer is that nothing about the build is private to me. Code sits in your Git repository from day one, the database runs in your cloud account, the schema is documented, and each module ships and goes live on its own rather than arriving as one big handover at the end. If you needed to bring in another developer mid-project, they would inherit a working system with history, not a black box.
Frequently asked questions
Is there low-cost ERP for a small manufacturing unit?
Yes, if you build only the modules you actually use. Most ERP cost comes from paying for a full suite when you needed inventory, purchase and production. Starting with those three and adding later keeps the first phase affordable.
Is a custom ERP better than off-the-shelf for a small factory?
Not automatically. If Tally Prime or a Zoho suite covers your process, buy it. Custom earns its place when your production flow is unusual, when you run job work across units, or when licence costs across many users exceed owning the system.
Can ERP integrate with Tally for accounting?
Yes. Sales, purchase and stock entries export in Tally-compatible form so operations run in the ERP while accounts stay where your accountant wants them.
Can it track raw material stock and reorder alerts?
Yes, with lead-time-aware reorder levels so purchase is triggered before a stockout rather than after. Consumption is deducted against production so stock reflects the floor, not last month.
Can it track production stages on the shop floor?
Yes. Work orders move through defined stages with quantity and rejection captured at each, so you can see where a batch actually is and where time is being lost.
What is the difference between ERP, CRM and POS?
CRM manages customers and sales before the order. POS handles the sale at the counter. ERP runs what happens behind both: purchase, stock, production, dispatch and accounts. Small businesses often need one of the three, not all.
How long does a custom ERP take?
Four to ten weeks for the first modules, longer for full coverage. It ships module by module and each goes live as it is finished, so you get value before the whole system is done.
What ongoing maintenance does an ERP need?
Hosting and backups, plus changes when your process changes or statutory formats are updated. Most clients use a small monthly retainer; some go months without needing anything.
What happens if I hire a freelance ERP developer and they become unavailable?
The code is in your repository and the database in your account from the first week, with each module shipped independently and documented. Another developer can pick it up from a running system rather than a handover document.
How long does ERP development take?
A single module ships in three to six weeks. A full multi-module ERP takes three to six months depending on complexity.
Can it work on phones?
Yes. The interface is mobile-first - warehouse staff can scan and update stock on a phone while office staff use desktop screens.
Can it integrate with existing accounting software?
Yes. Tally, Zoho Books and other accounting systems can be connected via API.
