Job Billing and Payments for Rooftop Solar Installers

Each solar job is billed in the stages you agreed with the customer. Invoices carry GST, each payment is posted to its job, and the office sees what is due before the crew moves on.

Invoices raised from the job

Advance and stage invoices

The advance at acceptance, a payment when material arrives and the balance at handover are taken from the payment stages on the proposal. Terms are yours.

Material and service lines

Panels, inverter, structure and installation work appear as lines. Extras such as a longer cable run are added as their own lines. Nothing is hidden in a lump sum.

GST on the invoice

Invoices are issued in a GST format. The rate and treatment for each item are decided by the client’s accountant and set up once.

Recording payments

Customers pay by bank transfer, cheque, UPI or cash. Each receipt is entered against the invoice, with the reference. Where a loan or subsidy is part of the payment, it is recorded as a separate receipt. Part payments leave a balance that stays visible on the job.

Money due

The owner sees which jobs have an invoice raised and unpaid. A balance on a commissioned plant stands out, and the person who calls the customer sees the amount and the invoice. Chasing starts from facts.

What billing does not do

  • It is not an accounting package. Ledgers and returns stay with your accountant.
  • Tally export is scoped during set-up, based on how your books are kept.
  • Subsidy and loan terms are between the customer, the bank and the scheme.
  • Payment gateway links are confirmed during scoping.
FAQ

Frequently asked questions

Can an invoice be raised before material arrives?

Yes. Which stage triggers each invoice follows your payment terms, and the office can raise one by hand if a stage changes.

Can the customer pay by UPI?

Yes. A UPI receipt is posted to its invoice, and a payment link can be added if you use a gateway. Cash is recorded too.

Can a bank-financed job be handled?

Yes. The customer’s share and the bank’s disbursement are recorded as separate receipts on the same job.

Does it show profit on a job?

It can show material issued and billed values side by side. Whether labour and overheads are counted is set with you.
