What This Is
WhatsApp refill reminder automation for pharmacies is a core capability of Ferbz’s Automation module, tightly linked with the Billing, Patients, Reminders board, and Reports sections. When a sale is recorded against a patient’s profile, Ferbz instantly creates a “Sale” record, generates a PDF receipt with a shareable link, and—without any extra clicks—enrolls that patient into any automation journeys whose trigger conditions match the new transaction.
The automation engine works in plain English. An owner simply writes a goal such as “remind every diabetes patient 5 days before their Metformin pack runs out” and Ferbz’s AI drafts a multi‑step WhatsApp Business API flow: a wait step (e.g., 5 days), a message step (the refill reminder), optional branching (if the patient replies “YES” or “NO”), and a follow‑up step (e.g., a confirmation link). All messages are sent through the official WhatsApp Business API provided by Gupshup, so they appear as a professional pharmacy number, not a personal phone.
Each reminder, broadcast, or confirmation consumes credits from the prepaid wallet (₹99 = 100 credits, ₹299 = 350 credits, ₹799 = 1,000 credits). There is no monthly subscription; the pharmacy tops up only for the volume it actually uses. The Reminders board shows live status—scheduled, sent, delivered, read, or failed—so the owner can instantly see if any reminder didn’t go through and re‑trigger it if needed.
In short, the feature replaces manual phone‑calls or paper notes with a fully automated, legally compliant WhatsApp reminder that starts the moment a chronic‑care sale is logged, runs on a visual canvas, and reports its impact in the Reports module. It is built for the Indian independent pharmacy, especially those in Tier 2 and Tier 3 cities where owners are often non‑technical and need a single dashboard to manage billing, inventory, CRM, and patient communication.
How Independent Pharmacy Owners Use It
Below is a step‑by‑step walkthrough of setting up a refill reminder journey for chronic‑care patients. Imagine Asha’s Health Pharmacy, a small shop in Jamshedpur that sells Metformin, Amlodipine, and insulin. Asha wants to remind every patient who buys a 30‑day Metformin pack to refill 5 days before the expected run‑out date.
1. Prepare the Patient List (optional bulk import)
- From the left navigation, click Patients.
- Press Import CSV and upload a file containing existing customers – name, phone (with country code), GSTIN (if applicable), and any custom tags (e.g., “Diabetes”).
- Ferbz validates the numbers and creates a patient profile for each row. Asha tags all diabetes patients with the label Diabetes for easy filtering later.
2. Record a Sale (this triggers the reminder clock)
- Go to Billing → New Sale.
- Select the patient “Rohit Kumar” (already in the CRM).
- Add items: Metformin 500 mg – 30 tablets – ₹210 (12 % GST).
- Click Checkout. Ferbz instantly generates a PDF receipt, stores it, and shows a Shareable link that can be sent via WhatsApp if Asha wishes.
- As soon as the sale is saved, the system checks all active automation journeys for matches.
3. Create the Automation Journey
-
Navigate to Automation from the main menu.
-
Click Create New Journey and type the plain‑English goal:
“Send a refill reminder 5 days before the Metformin pack runs out for any patient who bought Metformin.” -
Ferbz’s AI proposes a flow:
Trigger: Days until due – 5 days after the sale’s “expected finish date”.
Wait: 5 days.
Message: “Dear {{patient_name}}, your Metformin pack will finish on {{due_date}}. Reply ‘YES’ to confirm a refill or call us at 0661‑1234567.”
Branch: If reply ‘YES’ → send a confirmation link; if ‘NO’ → send a “We’re here when you’re ready” note. -
Click Edit on Canvas. The visual editor shows a rectangular node for the trigger, a clock icon for the wait, a speech‑bubble for the message, and a decision diamond for the branch.
-
Replace the placeholder text with Asha’s own wording, add the pharmacy’s WhatsApp Business number (already linked to the Gupshup API in the account settings), and attach the PDF receipt link as a variable
{{receipt_link}}if desired. -
Save the journey and Activate it. Ferbz records the journey’s credit cost (e.g., 2 credits per reminder sent, 1 credit per read receipt).
4. Verify on the Reminders Board
- Open Reminders board from the sidebar.
- You will see a line item: “Rohit Kumar – Metformin – Reminder scheduled for 2026‑10‑12”. The status shows Scheduled.
- After 5 days, the status automatically changes to Sent, then Delivered, and finally Read once Rohit opens the message. Any failure (e.g., invalid number) appears as Failed, with a red icon and a “Retry” button.
5. Review Effectiveness in Reports
-
Go to Reports → Messaging.
-
Set the date range to the last 30 days.
-
The table shows:
Total reminders sent: 124
Delivered: 119 (96 %)
Read: 94 (78 %)
Refill confirmations: 57 (48 % of reads) -
Cross‑reference with Billing to see that 57 additional Metformin sales occurred within the next 7 days, directly attributable to the reminder flow.
6. Adjust or Duplicate the Journey for Other Medicines
- Return to Automation, clone the Metformin journey, rename it “Amlodipine Refill”.
- Change the trigger condition to “Amlodipine” and adjust the wait period to 7 days (Amlodipine packs are usually 60 days).
- Activate the clone. Now both chronic‑care medicines are covered without recreating the flow from scratch.
7. Top‑up Credits When Needed
- If the credit balance falls below the projected monthly usage, click the Wallet icon on the top right.
- Choose a package (e.g., ₹299 for 350 credits) and pay via Razorpay.
- Credits are added instantly; the automation continues without interruption.
By following these steps, Asha’s Health Pharmacy moves from a manual, paper‑based reminder system to a fully automated, data‑driven WhatsApp refill reminder engine that runs 24 × 7, uses only the credits she pays for, and provides real‑time visibility on every patient interaction.
Why It Helps
Time saved: Before automation, Asha spent an average of 12 minutes each evening calling 8‑10 chronic‑care patients to ask about refills. Over a month, that’s roughly 5 hours of lost selling time. With Ferbz, the same 8 reminders are generated automatically, freeing 302 minutes per month for inventory checks or customer service.
Revenue recovered: In the month prior to automation, Asha recorded 42 missed refill opportunities (patients who never returned). After launching the Metformin and Amlodipine journeys, the Refill Confirmation metric rose to 57 confirmations, translating to an extra ₹12,870 in sales (average sale ₹225, 57 × ₹225). That is a +30.5 % increase in chronic‑care turnover for just 2 credits per reminder.
Stock turnover: Expired stock loss dropped from ₹4,200 (average monthly expiry of 20 tablets) to ₹1,100 because patients refilled before the pack ran out, allowing Asha to reorder in smaller batches.
Accuracy and compliance: All messages are sent through the official WhatsApp Business API, so they carry the pharmacy’s verified business name, avoiding the risk of personal‑number bans. The Reminders board instantly flags any failed delivery, letting Asha re‑send or correct the number before the refill window closes.
Financial predictability: Because Ferbz uses a prepaid credit model, Asha knows exactly how much each reminder costs (e.g., 2 credits ≈ ₹0.20). If she expects 150 reminders a month, she can budget ₹30 for messaging, separate from her inventory expenses. There is no hidden subscription fee, and the credit balance can be topped up at any time via Razorpay.
Overall, the automation directly tackles the two biggest pain points for Indian independent pharmacies: patients forgetting to return for refills and the resulting waste of stock. By turning a manual phone‑call process into an automated, trackable WhatsApp journey, Asha can keep chronic‑care patients returning on schedule, improve cash flow, and focus on serving the community rather than chasing overdue prescriptions.

Do I need a separate WhatsApp number for each pharmacy location?
A: No. Ferbz sends all messages through the official WhatsApp Business API account you configure once in the settings. The same number can be used for every branch, and all messages appear as coming from your pharmacy’s verified business profile.
What happens if a patient’s phone number is wrong or the message fails to deliver?
A: Failed deliveries are shown on the **Reminders board** with a red “Failed” badge. You can click the “Retry” button to resend after correcting the number, or manually reach out by phone. Credits are only deducted when the message is successfully sent.
Can I customize the reminder text for different medicines?
A: Yes. In the Automation canvas you edit the message node. You can insert variables like `{{patient_name}}`, `{{medicine_name}}`, and `{{due_date}}`, and you can create separate journeys for Metformin, insulin, or vitamin supplements, each with its own wording.
How do I know how many credits a reminder will cost?
A: Each WhatsApp message consumes 2 credits; a read receipt consumes 1 credit. The credit cost is displayed in the Automation setup screen before you activate the journey, and the **Reports** module shows total credits spent per date range.
Is GST applied to the credit purchases?
A: Yes. Credits are sold as a service and attract 12 % GST, which is automatically added to the Razorpay invoice. Your pharmacy can claim this GST input credit if you are registered under the regular GST scheme. ---
