Solar ERP software has to follow material from the purchase order to the rooftop and the money from the quotation to the bank. A generic ERP tracks stock and invoices; a solar ERP also knows serial numbers, warranties, project-wise costs and DISCOM paperwork.
1. Stock by warehouse, with transfers
Panels, inverters, structures and cables sit in more than one godown and often on a vehicle. The ERP should hold stock per product and per warehouse and record every transfer between them, so the number on screen is the number on the shelf.
2. Serial numbers all the way through
Panels and inverters are sold with serial numbers, and warranty claims, subsidy paperwork and service calls all ask for them.
- Receive goods by scanning serial numbers, not typing them.
- Issue material to a project and keep the serial against the customer.
- Look up any serial and see where it was bought, where it was installed and its warranty.
3. Purchase orders and goods receipt
- Raise a purchase order to a vendor, receive goods against it, and see what is still pending.
- When an accepted quotation needs material that is not in stock, the shortage should become a purchase requirement automatically.
- One way to receive goods, not three, so the stock ledger has one source of truth.
4. Project-wise material and cost
The question every owner asks is whether a job made money. That needs material issued to the project, expenses booked against it, payments received on it, and a profit figure that updates itself. If it needs a spreadsheet at month end, the ERP is not doing its job.
5. GST and the books
- Invoices with HSN codes and CGST, SGST or IGST by place of supply.
- Payments that land on the right invoice.
- A ledger that posts itself, so the accountant is not re-entering the day's work.
- A bank balance that moves when a payment or an expense is booked.
6. After-sales: warranty, service and AMC
Installation is the start of a long relationship. Look for equipment warranties tied to serial numbers, service tickets, and AMC contracts with renewal dates, so the next sale or the next repair is visible.
7. Signs that an ERP is too heavy or too light
- Too heavy: months of setup, a consultant for every change, and screens built for a factory.
- Too light: stock as a single number per product, no warehouses, no serial numbers.
- Just right: set up in days by your own team, with your product catalogue imported from a spreadsheet.
