Automated WhatsApp follow-up reminders convert viral-surge shoppers into loyal repeat buyers

Below is a step‑by‑step walkthrough that mirrors a screen‑recording of a shop owner, Ramesh’s General Store in Bhopal, setting up an automation to convert the surge of customers who bought “rice‑flour packets” after a local festival into repeat buyers.

1. Prepare the Customer List (optional bulk import)

1. From the left‑hand navigation, click Customers.
2. Press Import CSV and upload a file containing the phone numbers of customers who bought during the festival (Ramesh already exported the day‑wise sales from his POS).
3. Ferbz matches each row to an existing profile or creates a new one, attaching the phone number, name and address.

2. Create a WhatsApp Template (if not already done)

1. Go to Automation → Templates.
2. Click New Template, choose Text or Image with Caption (Ramesh selects Image with Caption to show a picture of the rice‑flour packet).
3. Write the message:

   नमस्ते {{customer_name}}! आपका {{product_name}} 7 दिन में समाप्त हो रहा है। आज ही दोबारा ऑर्डर दें और 10% छूट पाएं। लिंक: {{order_link}}
   

4. Submit for WhatsApp approval. Once approved, the template appears with a green check‑mark.

3. Build the Automation Journey

1. Click Automation on the main menu, then Create New Journey.

2. In the Goal field, type: “Remind customers who bought rice‑flour in the last 7 days to reorder before the weekend.”

3. Ferbz’s AI suggests a flow:

   • Trigger: Order completes → Days since last order ≥ 7
   • Wait: 2 days (to give the customer time to notice the stock level)
   • Message: Use the approved “Rice‑Flour Reminder” template
   • Branch: If message read → send discount code; else → send simple reminder

4. Drag the blocks onto the canvas, connect them, and click Edit on each block to fine‑tune:

   • Trigger: Set Product filter = “Rice‑Flour” and Days since order = 7.
   • Wait: Enter 2 days.
   • Message: Select the “Rice‑Flour Reminder” template, map the variables ({{customer_name}}, {{product_name}}, {{order_link}}).
   • Branch: Add a Condition “Message read = true”. For the true path, add a second Message block with a “10% discount code” template; for false, keep the first reminder only.

5. Click Save & Activate. The journey now appears in the Active Journeys list.

4. Process a New Sale (the trigger point)

1. When a customer buys a packet of rice‑flour, the cashier opens Billing → New Sale.
2. Select the customer’s profile (auto‑filled from the phone number entered at checkout).
3. Add the product “Rice‑Flour – 1 kg” and quantity.
4. Click Checkout. Ferbz instantly creates a PDF receipt, uploads it to the cloud, and generates a shareable link (e.g., https://ferbz.com/receipt/ABC123).
5. The Automation engine detects the order, checks the active journey’s filter, and enrolls the customer. The reminder clock starts: 7 days after this order, the system will wait 2 more days and then fire the WhatsApp reminder.

5. Monitor Reminders on the Board

1. Navigate to Reminders board.
2. The newly enrolled reminder appears under Scheduled with columns: Customer, Trigger date, Scheduled send date, Status.
3. When the message is dispatched, the status changes to Sent; later it updates to Delivered and finally Read (if the customer opens the chat).

6. Review Impact in Reports

1. After a week, open Reports → Messaging.

2. Filter by the journey name “Rice‑Flour Reorder”.

3. The dashboard shows:

   • Messages Sent: 48
   • Delivered: 45 (93.8%)
   • Read: 38 (79.2%)
   • Orders generated: 12
   • Revenue from reminders: ₹4,320 (average order value ₹360)

4. Export the report as CSV for accounting or GST filing.

Full Worked Example – Ramesh’s General Store

Date	Customer	Product	Order Value	Trigger Date (7 days later)	Reminder Sent (2 days after)	Message Read?	Follow‑up Action	Revenue from Reminder
12 Mar 2024	Sunita Sharma	Rice‑Flour 1 kg × 2	₹180	19 Mar	21 Mar (WhatsApp)	Yes	Discount code “WELCOME10” sent	₹360
13 Mar 2024	Amit Verma	Rice‑Flour 1 kg × 1	₹90	20 Mar	22 Mar (WhatsApp)	No	No further message	₹0
14 Mar 2024	Priya Kumar	Rice‑Flour 1 kg × 3	₹270	21 Mar	23 Mar (WhatsApp)	Yes	Discount code sent	₹540
…	…	…	…	…	…	…	…	…

From the table, Ramesh sees that out of 30 customers who bought rice‑flour during the festival, 12 placed a repeat order after the reminder, contributing an extra ₹4,320 in just two weeks. All of this was achieved without any manual phone calls or paper‑based follow‑ups.

Time saved

Before Ferbz, Ramesh’s shopkeeper spent roughly 15 minutes per day writing reminder SMS or calling customers individually. With the automation, the entire follow‑up process is handled by the system; the only manual step is the initial order entry, which already takes 2 minutes. Over a month, that is a saving of ≈ 7 hours of labour (15 min × 30 days ÷ 60).

Revenue recovered

During the March festival, the store saw a 30 % surge in rice‑flour sales (₹12,600). Historically, only 20 % of those customers returned within the next month. After enabling the WhatsApp reminder journey, the repeat‑order rate rose to 38 %, generating an extra ₹4,320 in revenue (12 additional orders × ₹360 average). That is a 34 % increase in post‑surge sales, directly attributable to the automated reminders.

Fewer manual errors

Paper‑based stock logs often missed the “reorder point” for fast‑moving staples. Ferbz’s Billing module automatically records the quantity sold, and the Automation trigger can be set to “days since last order” for each product. This eliminates the risk of forgetting to remind a customer who bought a single packet of detergent three weeks ago.

Credit‑based cost control

Ramesh topped up ₹299 (350 credits). Each reminder consumed 3 credits, and each broadcast (used only for a seasonal promotion) consumed 5 credits. After the first month, he used 120 credits for reminders and 30 credits for a single broadcast, leaving 200 credits for the next cycle. The prepaid model ensures he pays only for the messages that actually fire, avoiding hidden subscription fees.

Compliance and trust

Because messages are sent through the official WhatsApp Business API, customers see a verified business badge, which improves trust compared with personal‑number messages. Moreover, the system logs every delivery status, providing an audit trail useful for GST reporting and for proving that promotional messages were sent in compliance with Indian telecom regulations.

Overall, the automated WhatsApp follow‑up reminders turn an unpredictable viral surge into a measurable, repeat‑purchase engine, while freeing shop owners from manual outreach, cutting costs, and delivering clear ROI.
