Gym billing app with GST: invoices and fee receipts your members can open on WhatsApp

Add your GSTIN in Settings and membership invoices show your gym's name, address and GSTIN, an invoice number and date, the member, service code 999723, the taxable value, CGST and SGST, the total and every payment received.

Your plan prices are treated as GST-inclusive, which is how most gyms quote, so nothing you charge changes. The tax is worked out from inside the price. A ₹1,500 plan at 5% shows ₹1,428.57 taxable value, ₹35.71 CGST and ₹35.72 SGST.

Not registered? Members get a clear fee receipt with what they paid for, the dates and the amount, and no tax lines, which is what an unregistered gym issues. Whether you need to register depends on your turnover and state. Ask a chartered accountant. Jimwala works either way.

• The GSTIN and rate are saved on each invoice when it is issued, so changing them later does not alter invoices members already have.
• Invoices are numbered one after another, like INV-00123. A cancelled invoice keeps its number and shows as cancelled.
• Part payments are listed with date, method and reference, such as a UPI transaction number, followed by the balance still due.

On a member's Payments tab, tap the WhatsApp button. The chat opens with the message and receipt link typed. The member can download a PDF or print from their phone.

Jimwala does not file GST returns. It prepares invoices and keeps records, and the filing happens on the GST portal, usually by your accountant. Shop sales such as supplements get a plain receipt for now, not a GST invoice. Rates can change, so check the current one with your accountant. You can set the rate in Jimwala.
