Automated WhatsApp Refill Reminders that Keep Your Pharmacy Stocked

Below is a step‑by‑step walkthrough of how a pharmacy owner in a Tier‑2 city such as Bhopal would set up and run refill reminders for chronic‑care patients. Imagine the pharmacy is called Arogya Pharmacy and today it is 12 September 2026.

1. Prepare Patient Data

1. From the left‑hand menu click Patients → Import CSV.

2. Upload a file containing columns: PatientID, Name, Phone, Medicine, LastSaleDate, QtyDispensed, DailyDose.

3. Ferbz parses the file and creates a profile for each patient. For example, the row:

   P001, Sunita Sharma, 9876543210, Metformin 500 mg, 2026‑08‑15, 30, 1
   

   tells Ferbz that Sunita bought 30 tablets on 15 August, taking one tablet per day, so her next refill is due on 14 September.

2. Record the Sale

1. Go to Billing → New Sale.

2. Search for “Sunita Sharma” (the patient appears automatically).

3. Add the item Metformin 500 mg – 30 tablets at the GST‑applicable rate (12 % GST).

4. Click Checkout. Ferbz generates a PDF receipt, stores it, and automatically creates a Sale record linked to Sunita’s patient profile.

   Result: The reminder clock for Sunita is now active.

3. Build the Refill Automation

1. Navigate to Automation → Create New Journey.

2. In the plain‑English prompt box type:

   “Send a refill reminder 3 days before the medication runs out, then a follow‑up after 2 days if there is no reply, offering a 5 % discount on the next purchase.”

3. Click Generate. Ferbz’s AI builds a canvas with three nodes:

   • Trigger – “Days until due = 3”.
   • Message 1 – “Hi {PatientName}, your {MedicineName} will run out on {DueDate}. Reply ‘YES’ to confirm a refill.”
   • Wait 2 days – branch based on response.
   • Message 2 (No reply) – “We noticed you haven’t confirmed your refill. Get 5 % off if you order within the next 48 hrs.”

4. Review each node. Replace the generic discount text with your own template:

   🎉 Special Offer: Use code REFILL5 at checkout for 5 % off your next purchase.
   

5. Save the journey as “Metformin Refill Reminder”.

4. Enroll Patients Automatically

Because the journey’s trigger is “days until due”, Ferbz evaluates every patient’s DueDate (calculated as LastSaleDate + (QtyDispensed / DailyDose)). When Sunita’s due date (14 Sep) is three days away (11 Sep), the system automatically enrolls her into the journey. No manual tagging is required.

5. Monitor the Reminder Flow

1. Open Reminders board from the main menu.
2. Use the filter dropdown to show “Active – Metformin Refill Reminder”.
3. You will see Sunita’s entry with status Scheduled → Sent → Delivered → Read (timestamps appear next to each).

If a reminder fails (e.g., phone number invalid), the board flags it in red and you can re‑send manually or correct the contact.

6. Follow‑up and Close the Loop

When Sunita replies “YES”, the automation marks her as Converted and logs the interaction. The pharmacy owner can now open the patient profile, click Create Sale, and process the refill. The system automatically adds the 5 % discount if the owner applies the discount code during checkout.

If Sunita does not reply, the second message is dispatched automatically after the 2‑day wait. The owner can see the open‑rate and click‑through statistics in Reports → Messaging Effectiveness, which shows that, for this journey, 78 % of reminders were read and 42 % resulted in a refill within 7 days.

7. Credit Consumption

Assume each WhatsApp message consumes 1 credit. Sunita’s flow used 2 credits (reminder + follow‑up). The owner’s wallet shows –2 credits deducted instantly after the messages are sent. If the owner had topped up ₹299 for 350 credits last week, the balance now reads 348 credits.

Full Worked Example

Step	Action	Result
1	Import CSV of 150 chronic patients	All profiles created
2	Record a Sale for Sunita Sharma (30 Metformin)	Reminder clock starts
3	Create “Metformin Refill Reminder” journey	AI builds 3‑step flow
4	System auto‑enrolls Sunita on 11 Sep (3 days before due)	Reminder scheduled
5	11 Sep 10:00 AM – WhatsApp sent, status Delivered	Sunita reads at 10:05 AM
6	Sunita replies “YES” at 10:12 AM	Journey marks Converted, discount applied
7	Owner creates refill Sale, 5 % discount applied, GST 0 % (insulin exemption)	Revenue recorded, stock reduced
8	Wallet shows –2 credits (total 348)	Credit balance updated

By following these steps, Arogya Pharmacy turns every sale into a proactive refill pipeline without lifting a pen after the initial billing.

Time saved – Before automation, the pharmacist spent an average of 12 minutes per patient each evening calling or texting to ask about refills. With Ferbz, the same 150 patients are reminded automatically, freeing ≈30 hours per month for counselling or inventory work.

Revenue recovered – In a typical month, Sunita’s pharmacy lost about 18 % of chronic‑care sales because patients forgot to return. After deploying the reminder journey, the conversion rate rose from 42 % to 68 % for Metformin refills, adding ₹9,850 (≈ ₹145 per successful refill) to the bottom line in the first 30 days.

Stock optimisation – The pharmacy’s stock of Metformin dropped from 2,400 tablets to a more realistic 1,650 tablets, reducing expiry waste by ≈ 12 % (≈ ₹3,600 GST‑adjusted loss avoided).

Accurate GST handling – Because each sale is recorded in Billing, the system automatically applies the correct 12 % GST for generic medicines and 0 % GST for essential items like insulin, eliminating manual tax calculation errors.

Zero‑failure visibility – The Reminders board surfaces any undelivered messages instantly. In the first week, only 2 of 150 reminders failed (invalid numbers), allowing the owner to update contacts and avoid silent loss.

Overall, the Automated WhatsApp Refill Reminder converts a manual, error‑prone process into a measurable, credit‑based workflow that protects revenue, reduces expired inventory, and lets the pharmacy focus on patient care rather than chasing phone numbers.
