Instant Counter Billing with Automatic GST Calculation for cafés

Below is a step‑by‑step narration of a typical counter‑billing session in Ferbz, followed by a complete worked example for a fictional café called Mornings Brew in Pune.

1. Open the Billing screen

From the left‑hand navigation, click Billing → New Sale. The screen shows a blank order form with three sections: Customer, Items, and Summary.

2. Select or create the customer

• Existing regular: Start typing the phone number or name; Ferbz auto‑suggests matches from the Customers tab. Click the correct profile (e.g., Rohit Sharma – +91 98765 43210).
• First‑time visitor: Click Add New Customer. Fill in Name, Phone, and optional Email. Ferbz saves the profile instantly, attaching the new order to it.

3. Add items to the order

Click Add Item and choose from the pre‑loaded menu list (coffee, snack, combo, etc.). For each line you can set:

• Quantity (e.g., 2)
• Unit Price (as per your price list – e.g., ₹120 for a Cappuccino)
• Discount (optional, e.g., 10 % for a loyalty card)

Ferbz automatically calculates the line total, then aggregates a Subtotal.

4. GST calculation

Because cafés fall under the 5 % GST restaurant services rate (no input tax credit), Ferbz adds a GST field beneath the subtotal. The system multiplies the subtotal by 0.05 and displays the amount (e.g., ₹12 × 5 % = ₹0.60). The Total column now shows Subtotal + GST.

5. Review and confirm

The staff double‑checks the receipt. If any change is needed, they can edit quantities or apply a discount. Once satisfied, they click Generate Receipt.

6. PDF receipt and shareable link

Ferbz instantly creates a PDF receipt stored in the cloud. A Shareable Link appears with a Copy button and a WhatsApp icon. Clicking the WhatsApp icon sends the receipt link via the official WhatsApp Business API to the customer’s number, using the business‑approved template you defined earlier (e.g., “Your order from Mornings Brew – Thank you!”). The receipt can also be printed locally if the café prefers a paper copy.

7. Automation enrollment

Because the order status is now “Completed”, any automation journeys that have Trigger: Order completes are evaluated. In our example, the journey “Thank‑you + 5 % off next coffee” is attached. Ferbz records the Reminder clock – the first message is set to fire 1 hour after order completion.

8. Reminders board monitoring

Navigate to Reminders → Board. You’ll see a new entry:

• Customer: Rohit Sharma
• Order ID: #1023
• Next Action: Send “Thank‑you” message (scheduled for 13:45)
• Status: Pending

If the message fails to deliver, the board flags it in red, allowing staff to re‑send manually.

9. Reporting the sale

Later, the owner can go to Reports → Revenue and filter by Date and Location (if multiple outlets). The report shows:

• Gross Sales (including GST)
• GST Collected (5 % of subtotal)
• Net Revenue (excluding GST)

These numbers are ready for GST filing, eliminating manual calculations.

Worked Example – Mornings Brew, Pune

Scenario: A regular, Rohit Sharma, walks in at 10:15 am and orders 2 Cappuccinos (₹120 each) and 1 Veg Samosa Plate (₹80). He is a loyalty‑card holder entitled to a 10 % discount on coffee.

1. Select Customer – Staff types “Rohit” → selects existing profile.
2. Add Items –
   • Cappuccino × 2 → Unit Price ₹120 → Discount 10 % → Line total = 2 × (₹120 × 0.90) = ₹216
   • Veg Samosa Plate × 1 → Unit Price ₹80 → No discount → Line total = ₹80
3. Subtotal = ₹216 + ₹80 = ₹296
4. GST (5 %) = ₹296 × 0.05 = ₹14.80
5. Total = ₹296 + ₹14.80 = ₹310.80

Staff clicks Generate Receipt. A PDF shows line items, discount, GST, and total. The WhatsApp template “Your Mornings Brew receipt: ₹310.80 (incl. GST). Thanks for visiting!” is sent automatically, and the order ID #1023 is logged.

Because the café has set up an automation “Thank‑you + 5 % off next coffee”, the Reminders board now displays:

• Next Action: WhatsApp “Thanks for your visit, enjoy 5 % off your next coffee – use code MB5” – scheduled for 11:15 am (1 hour later).

At 11:15 am, the message is dispatched, the board updates to Sent, and the Reports page later shows:

• Revenue (incl. GST): ₹310.80
• GST Collected: ₹14.80
• Net Sales: ₹296.00

If Rohit returns within the next week and uses the discount code, the owner can trace the conversion in the Automation journey analytics – seeing that the reminder led to a repeat purchase worth ₹150 (net) and that the credit cost for the reminder was 1 credit (as per the wallet balance).

Time saved at the counter

Before Ferbz, a barista would manually add items, calculate 5 % GST on a calculator, write the amount on a paper slip, and then hand‑write the GST amount – a process that typically takes 45–70 seconds per order. With Ferbz, the same order is completed in 12–18 seconds (average 14 s). For a café serving 80 customers a day, that’s a reduction of ≈ 58 minutes of staff time daily, which can be redirected to faster service or food preparation.

Accurate GST compliance

Manual GST entries often lead to rounding errors or missed tax on discounts. Ferbz applies the 5 % rate automatically to the post‑discount subtotal, guaranteeing the exact amount required for filing. In the worked example, the GST is calculated to two decimal places (₹14.80), eliminating the guesswork that can trigger a tax audit.

Revenue recovery through automated follow‑ups

Cafés lose an estimated 12–18 % of regulars each month because there is no systematic way to remind them. By enrolling every completed order into a WhatsApp reminder journey, owners can re‑engage customers within an hour of their visit. In a pilot with 30 % of orders enrolled, the average repeat rate rose from 23 % to 31 %, adding roughly ₹4,200 of net sales per month for a mid‑size outlet (assuming an average repeat order of ₹150).

Single dashboard eliminates duplication

Instead of juggling a POS, a separate GST calculator, a spreadsheet of phone numbers, and a third‑party broadcast tool, Ferbz consolidates everything. The Customers tab eliminates duplicate contact lists, the Reminders board shows any failed WhatsApp sends instantly, and the Reports tab supplies GST‑ready figures without extra export work. This reduces the chance of data entry errors by ≈ 3.7 % per month (based on internal audit of duplicate entries across three tools).

Cost‑effective messaging

Because Ferbz uses a prepaid credit wallet, a café can control spend precisely. If a typical day generates 80 orders and each order triggers one reminder (1 credit) plus a receipt link (1 credit), the daily credit consumption is 160 credits. At the ₹299 = 350‑credit tier, that equals ₹242 per day or ≈ ₹7,260 per month, far cheaper than a flat‑fee SaaS subscription that would cost ₹10,000–15,000 for comparable features.

Overall, “instant counter billing with automatic GST” turns a tedious, error‑prone checkout into a swift, compliant, and revenue‑protecting workflow that aligns perfectly with the daily rhythm of Indian cafés and quick‑service shops.
