Instant, GST‑compliant billing that speeds up payments for spa owners

Below is a step‑by‑step walkthrough of the fast‑billing workflow, illustrated with a realistic example for Tranquil Touch Spa, a boutique wellness centre in Jaipur.

1. Open the Dashboard
   Log in at https://dashboard.ferbz.com/. The home screen shows the main navigation bar on the left: Clients, Bookings, Billing, Therapists, Automation, Broadcasts, Reminders, Reports.

2. Select the Client
   Click Clients → use the search bar to type “Rohit Mehta”. The client profile appears, displaying his phone number, email, and a list of past bookings. If Rohit is a new visitor, click Import CSV at the top of the Clients page to bulk‑upload his details, or press Add New and fill the mandatory fields (Name, Mobile, GSTIN if applicable).

3. Create a Booking
   From the client’s profile, hit New Booking. Choose the date and time – e.g., 12 Oct 2024, 3:00 PM – and select the therapist Anita Sharma from the Therapists dropdown. The service list shows “Swedish Massage – 90 min – ₹2,500”. Add any add‑ons such as “Aroma Oil – ₹300”. Click Save Booking. Ferbz instantly sends a WhatsApp confirmation to Rohit’s number using the official API, and the booking appears on the Appointments calendar.

4. Ring Up the Sale (Fast Billing)
   With the booking saved, click the Billing tab on the left menu, then press New Sale. The screen shows a Client selector – Rohit’s name is already highlighted because the booking was just created.

   • Service line: The system auto‑populates “Swedish Massage – 90 min – ₹2,500”.
   • Add‑on line: “Aroma Oil – ₹300”.
   • GST selection: Because Tranquil Touch Spa’s annual turnover is ₹38 lakh, it is registered under the composition scheme. Ferbz automatically applies the composition‑scheme GST rate of 6 % on the total (₹2,800 × 6 % = ₹168). The UI shows both the regular 18 % option (greyed out) and the composition rate (selected).

   The Subtotal reads ₹2,800, GST ₹168, Total ₹2,968. All amounts are displayed in Indian rupees with two‑decimal precision.

5. Generate and Send the PDF Receipt
   Click Generate Receipt. Ferbz builds a PDF that includes:

   • Spa name, address, GSTIN (29AAACB1234F1Z5)
   • Client name and contact
   • Booking reference number (BKG‑20241012‑001)
   • Itemised list with GST breakdown
   • Total amount payable

   A Shareable Link appears beneath the PDF preview. Click Send via WhatsApp. The system pulls the pre‑configured template “Your receipt for today’s session” from the Automation library, inserts the link, and dispatches the message through the WhatsApp Business API. The message status changes to Sent on the Reminders board; a few seconds later it updates to Delivered and finally Read when Rohit opens it.

6. Automatic Reminder Clock Starts
   Because the receipt was sent, Ferbz automatically enrolls Rohit into the “Post‑session follow‑up” automation (set up under Automation → “Win‑back after 30 days”). The trigger “days since last booking” is now counting from the moment the receipt link was shared. This means the next reminder – a gentle “We hope you enjoyed your massage, would you like to book your next session?” – will be scheduled exactly 30 days later, without any extra manual input.

7. Credit Deduction
   Each WhatsApp send consumes credits from Tranquil Touch Spa’s prepaid wallet. Assuming the standard rate of 1 credit per message, the receipt send deducts 1 credit. The wallet balance is visible on the top‑right corner of the dashboard; if it falls below the required threshold, a Top‑up button opens the Razorpay modal (₹99 = 100 credits, etc.).

8. Review in Reports
   After a week, the owner clicks Reports → Revenue → selects the date range 01‑Oct‑2024 to 07‑Oct‑2024. The report shows:

   • Total sales: ₹2,968
   • GST collected: ₹168 (18 % of taxable amount, or composition‑scheme rate)
   • Credits used for receipts: 1

   The owner can also view Messaging Effectiveness to see that 92 % of receipt messages were read, confirming that clients receive the invoice promptly.

Full Worked Example Recap

• Business: Tranquil Touch Spa, Jaipur
• Client: Rohit Mehta
• Service: Swedish Massage (₹2,500) + Aroma Oil (₹300)
• GST (composition scheme 6 %): ₹168
• Total invoice: ₹2,968
• Credits used: 1 (receipt WhatsApp) + 1 (confirmation message) = 2 credits
• Time from service completion to receipt delivery: < 30 seconds
• Next automated reminder scheduled for 11 Nov 2024 automatically

By following these clicks, the spa owner moves from a paper receipt and manual follow‑up to a fully compliant, instant billing cycle that fuels the rest of Ferbz’s automation.

Time saved – The entire billing sequence (client lookup, service selection, tax calculation, PDF generation, WhatsApp send) takes roughly 45 seconds on Ferbz. The same process using a spreadsheet, a separate invoicing app, and a manual WhatsApp copy‑paste can easily exceed 7 minutes per client. For a spa that handles an average of 12 bookings per day, that translates to 5 hours 45 minutes saved each week.

Revenue recovered – Because the receipt is delivered instantly via WhatsApp, clients see the amount owed while the therapist is still on the premises. In a pilot at a Hyderabad wellness centre, the average payment collection lag dropped from 3 days to under 1 hour, reducing outstanding dues by ₹12,340 in the first month. Faster cash flow means the owner can reinvest in stock, pay therapists on time, and avoid GST penalties.

Fewer manual steps – No separate GST filing data entry is needed; the invoice already contains the correct GSTIN, rate, and amount. The Clients profile automatically logs the payment, so the next booking shows a “last paid” date, enabling the “win‑back after 30 days” automation to fire without any extra tagging. This eliminates the common error of forgetting to mark a client as “paid”, which often leads to missed rebooking reminders.

Compliance assured – The module respects the two tax regimes relevant to Indian spas: 18 % GST for regular registrants and the 6 % composition scheme for eligible providers. The system prevents the owner from accidentally applying the wrong rate, and the PDF receipt meets the format required by the GST portal, reducing the risk of audit adjustments.

Credit transparency – Because every WhatsApp send draws from the prepaid wallet, the owner sees exactly how many credits are spent on receipts versus promotional broadcasts. This clear accounting prevents surprise expenses and lets the owner allocate budget precisely (e.g., 200 credits per month for receipts, 300 for re‑engagement messages).

Overall, fast billing turns a fragmented, error‑prone checkout into a single, GST‑compliant click, accelerates cash inflow, and feeds the automated reminder engine that drives repeat bookings – the core growth lever for any independent spa or wellness centre in India.
