What This Is
WhatsApp reorder reminders for retail shop is a built‑in Ferbz capability that turns every completed Order into a timed, automated follow‑up message sent through the official WhatsApp Business API. The flow lives inside three core Ferbiz modules: Billing, Automation, and Reminders board.
When a cashier rings up a customer in the Billing → New Sale screen, Ferbz instantly creates a PDF receipt and a shareable link. As soon as the receipt is generated, the system marks the transaction as “completed” and automatically enrolls the customer in any Automation journeys whose trigger matches the event “order completes”.
An Automation journey is described in plain English – for example, “remind customers to reorder rice after 15 days”. Ferbz’s AI then drafts a multi‑step WhatsApp sequence, which appears on a visual canvas where the shop owner can edit the message, add a product image, or insert a short link to the receipt. The journey’s trigger can be days until due (e.g., 15 days after the last order) or days since last order (e.g., win‑back after 30 days of inactivity).
Once the trigger date arrives, Ferbz sends the message from the official WhatsApp Business API (partnered with Gupshup). Each send consumes credits from the prepaid wallet – the same wallet that pays for broadcasts and confirmation messages. The status of every reminder – scheduled, sent, delivered, read, or failed – appears in real time on the Reminders board, so the owner can see at a glance whether a reminder has reached the customer.
All customer data, including contact details, purchase history, and reminder history, lives on the Customers screen. The owner can import thousands of existing contacts via a CSV file, and each contact automatically inherits the same Automation rules once an order is recorded.
In short, the “WhatsApp reorder reminder” feature is a tightly coupled set of Ferbz modules that replace a manual phone‑call or paper note system with a reliable, credit‑based, API‑driven reminder that nudges shoppers to come back exactly when they are likely to need the product again.
How General Retail Stores Owners Use It
Below is a step‑by‑step walkthrough of how a typical shop – let’s call it Sharma’s General Store in Bhopal – sets up and runs automated WhatsApp reorder reminders for staple items such as rice, wheat flour, and cooking oil.
1. Prepare the Customer List
- Log in to Ferbz and click Customers on the left navigation.
- Press Import CSV and upload a file containing existing shoppers: name, mobile number, GSTIN (if applicable), and any notes (e.g., “prefers bulk rice”).
- Ferbz validates the numbers and creates a Customer profile for each entry. The profile shows a timeline of past Orders and a placeholder for future reminders.
2. Create a Reorder Automation Journey
-
From the main menu choose Automation.
-
Click New Journey and type the plain‑English goal:
remind customers to reorder wheat flour after 12 days -
Ferbz’s AI instantly drafts a three‑step flow:
- Wait 12 days (trigger: days since last order)
- Message 1 – “Namaste, Sharma ji! It’s been 12 days since you bought 5 kg wheat flour. Need a refill? Reply ‘YES’ to place an order now.”
- Branch – if the customer replies “YES”, jump to a Message 2 that contains a quick order link; otherwise, send a gentle “We’re here when you need us.”
-
The visual canvas shows each block. Click any block to edit text, attach a product image, or change the wait period. For this store we keep the wait at 12 days because most families finish a 5 kg pack in that time.
-
Save the journey and give it a name: Wheat Flour Reorder (12‑day).
3. Link the Journey to the Billing Event
- Go to Billing → Settings (gear icon on the Billing screen).
- Under Automation Triggers, enable “When an Order completes” and select the newly created journey Wheat Flour Reorder (12‑day).
- Optionally, add a filter so the journey only enrolls customers whose last Order contained the SKU “Wheat Flour – 5 kg”. The filter uses the product code field from the receipt.
4. Process a Sale – The Trigger Fires
-
A regular customer, Ramesh Patel, walks in and buys 5 kg wheat flour for ₹1,200 (GST 0% as it is an unbranded staple).
-
The cashier opens Billing → New Sale, selects Ramesh’s profile, adds the product, and clicks Checkout.
-
Ferbz generates a PDF receipt, stores it, and immediately shows a shareable link.
-
Because the Automation trigger is active, Ferbz enrolls Ramesh in the Wheat Flour Reorder journey. The Reminders board now shows a new entry:
- Customer: Ramesh Patel
- Reminder: Wheat Flour Reorder (12‑day)
- Status: Scheduled – 12 days remaining
5. Credit Consumption
Each reminder that will be sent consumes 1 credit (the exact cost is defined by the wallet balance, not a subscription). Sharma’s store has previously topped up ₹299 for 350 credits. The upcoming reminder will deduct 1 credit when it is dispatched.
6. The Reminder Sends
- After 12 days, the Reminders board updates automatically: the status changes to Sent and shows a timestamp.
- A few seconds later, the status flips to Delivered; once Ramesh reads it, the board shows Read.
- If Ramesh replies “YES”, the Automation engine follows the branch and sends the second message with a quick‑order link. The link opens Ferbz’s checkout page pre‑filled with the wheat flour SKU, letting Ramesh confirm the order in two taps.
7. Monitoring Effectiveness
-
Navigate to Reports → Messaging.
-
Select the date range covering the last month.
-
The report lists:
- Total reminders sent: 84
- Delivered: 78 (92.9%)
- Read: 71 (84.5%)
- Reorder conversions: 19 (22.6%)
-
The owner can export this data as CSV for bookkeeping or GST filing (the GST rate for this product is 0%, so the revenue figure reflects pure sales).
8. Handling Failures
If a reminder fails (e.g., wrong number), the Reminders board flags it in red with a “Failed – Invalid number” note. The owner can click the entry, open the Customer profile, correct the mobile number, and click Resend. The resend consumes another credit, but the failed attempt is already accounted for, keeping the credit balance transparent.
9. Scaling to Other Products
Repeat steps 2‑4 for other high‑turnover items:
- Rice (20‑day) – wait 20 days, GST 0% for loose rice.
- Cooking Oil (15‑day) – wait 15 days, GST 5% for branded oil.
Each journey lives side‑by‑side, and the Reminders board aggregates all pending reminders, giving Sharma a single view of his entire follow‑up pipeline.
Why It Helps
Time saved – Before Ferbz, Sharma’s shopkeeper spent roughly 45 minutes each week calling customers to ask if they needed a refill. After automation, the same task is handled by the system, freeing ≈ 3 hours per month for stocking, invoicing, or attending to walk‑in customers.
Revenue recovered – In the first 30 days of using the wheat‑flour reminder, Sharma saw 19 repeat orders worth ₹22,800. Without reminders, the same period recorded only 7 repeat orders (≈ ₹8,400). That is a ₹14,400 uplift, equivalent to ~12 % of monthly turnover for a store with a ₹1.2 lakh average monthly sales figure.
Reduced manual errors – Paper‑based stock logs often missed the exact date a product was sold, leading to missed reorder windows. Ferbz timestamps every Order automatically, so the “days since last order” trigger is always accurate.
Credit‑controlled cost – The prepaid wallet makes spending predictable. Sharma topped up ₹799 for 1,000 credits and used ≈ 120 credits for reminders and a few broadcast promos in the first month, leaving a healthy balance for the next cycle. No surprise monthly fees appear on the bank statement.
Customer experience – Customers receive a friendly, timely WhatsApp nudge rather than an unexpected cold call. The read‑receipt data lets Sharma know the message was seen, and the quick‑order link reduces friction, encouraging a higher conversion rate than a phone call that may be missed.
Overall, the automated WhatsApp reorder reminders directly address the core pain points of repeat‑customer drift and lack of stock‑on‑hand visibility, turning a manual, error‑prone process into a data‑driven, credit‑controlled workflow that boosts both efficiency and sales.

Do I need a separate phone or QR code to send WhatsApp messages?
A: No. All messages are sent through Ferbz’s integration with the official WhatsApp Business API (partnered with Gupshup). You do not use a personal number or scan any QR code.
How are credits deducted for reminders?
A: Each reminder that is dispatched consumes one credit from your prepaid wallet. The deduction happens at the moment the message status changes to “Sent”. You can view the remaining balance on the Dashboard.
Can I edit a reminder after it has been scheduled?
A: Yes. On the **Reminders board** click the scheduled entry, edit the message or wait period, and save. The updated version will be used when the trigger fires, and only one credit will be deducted at send time.
What if a customer’s mobile number is wrong and the reminder fails?
A: The Reminders board will flag the entry as “Failed – Invalid number”. You can open the customer’s profile, correct the number, and click **Resend**. The resend will use another credit.
Is GST automatically calculated on the reminder messages?
A: The reminder itself does not calculate GST; it only references the original Order, which already contains the correct GST rate (0%, 5%, 12%, 18% or 28% as applicable). The receipt link in the message shows the proper tax breakdown for the customer. ---
