The problem

Growing manufacturers and distributors run stock in one sheet, purchase in another and sales in Tally, then spend days reconciling. Nobody trusts the stock number.

The fix

A custom ERP puts inventory, purchase, sales and GST in one system that fits how you actually work. We build it one module at a time, so the most painful part is fixed first.

Questions

Straight answers. Ask anything else in your brief and we reply within 24 hours.

We build ERP in modules. A single module such as inventory or purchase starts at ₹1.5L. A full system is quoted after a short paid scoping sprint, then built in fixed-price phases.

If an off-the-shelf ERP fits 90% of your process, use it and we will extend it. Custom makes sense when your process is your advantage or you are paying for many seats you work around.

Yes. GST invoices, e-way bills, HSN codes and returns-ready reports, and it can sync with Tally for your accountant.

Yes. Vouchers, ledgers and stock can sync with Tally, so accounts stay where your CA works.

Yes. We clean and import items, customers, vendors and opening stock as part of each module.

Each module takes 3 to 5 weeks. Most businesses go live with the most painful module first, then add the rest over 3 to 6 months.
