GST-ready solar quotations with CGST, SGST and IGST

How the totals are calculated

Each line is priced first: capacity times the rate per kilowatt for the system and the bill of materials, and unit price times quantity for an optional battery. A flat rupee discount is then subtracted from that line, and it can never exceed the line it applies to. GST is worked out on each discounted line and added up, rather than being derived from an already-rounded taxable total.

• Taxable total, total GST and grand total are shown separately
• The system, bill-of-materials and battery lines each have their own GST rate
• Amounts are calculated in rupees and paise, never in floating point

CGST and SGST, or IGST

If your state and the customer's state match, total GST is split into CGST and SGST of equal value. CGST is rounded to the paisa and SGST takes the remainder, so the two always add up to the exact total. If the states differ, the whole amount is shown as IGST.

What you set up once

Your company's state is set in Settings and every customer record carries a state. If either is missing, Bharat Solar Venture asks you to add it instead of guessing. Your GSTIN is optional, and when you enter one its format is checked before it is saved.

Common mistakes

• Leaving a state out

  Your company's state is set in Settings and every customer record carries a state. If either is missing, Bharat Solar Venture asks you to add it instead of guessing.

• Expecting a tax invoice

  Bharat Solar Venture produces quotations only. It does not file returns and does not issue GST invoices.

• Assuming one rate fits every line

  The system line, the bill-of-materials line and the battery line each carry their own GST rate. Defaults come from your price book and battery catalog and can be changed on the quotation.

• Expecting old quotations to follow a rate change

  Rates are stored on the quotation. A change in your price book affects future quotations, while a finalized quotation keeps the rates it was issued with.

What to check before you send

• Your company's state is set in Settings
• The customer's state is on the customer record
• The GST rate on the system line, the bill-of-materials line and any battery line is correct
• If you entered a GSTIN, its format was accepted when you saved it
• The taxable total, total GST and grand total in the preview look right
