Automate refill reminders on WhatsApp and keep chronic‑care patients coming back with Ferbz

Below is a step‑by‑step walk‑through of how a typical independent pharmacy in Toronto would set up and run WhatsApp refill reminder automation for its chronic‑care patients.

1. Import or create patient records

   • From the left‑hand menu select Patients.
   • Click Import CSV and upload a spreadsheet that contains each patient’s name, phone number (in international format), date of birth, and the date of their last refill.
   • Ferbz automatically creates a patient profile for each row, showing a timeline of past Sales and any previous reminder activity.

2. Configure the refill reminder automation

   • Navigate to the Automation tab.
   • Click Create New Automation and type the goal in plain English:
     “Send a WhatsApp refill reminder 5 days before a chronic‑care patient’s next medication is due.”
   • Ferbz’s AI generates a visual canvas with the following steps:
     • Trigger: “Days until due = 5”. The system reads the “next refill due date” that you will define in the patient’s profile.
     • Wait: none (the trigger fires exactly at 5 days out).
     • Message: a pre‑written WhatsApp template that says, “Hi {{patient.first_name}}, it’s time to refill your {{medication_name}}. Reply ✅ to confirm or call us at 416‑555‑1234.”
     • Branch: if the patient replies ✅, the flow moves to a Confirmation step that logs a “Refill confirmed” event; if no reply after 48 hours, a follow‑up reminder is sent.
   • Click Save and give the automation the name Chronic‑Care Refill Reminder.

3. Link the automation to the patient’s medication schedule

   • Open a patient profile (e.g., Maria Lopez).
   • In the History section click Add Medication Schedule.
   • Choose the medication (e.g., Metformin 500 mg), set the last dispensed date (e.g., 2024‑07‑12), and the quantity supplied (90 tablets). Ferbz automatically calculates the next refill due date (2024‑10‑10).
   • Toggle Enroll in Automation and select Chronic‑Care Refill Reminder. The patient is now part of the journey and will receive a reminder on 2024‑10‑05.

4. Process a new sale and start the reminder clock

   • When a patient comes in for a refill, go to Billing → New Sale.
   • Search for the patient’s name, select the medication, enter the quantity, and click Complete Sale.
   • Ferbz generates a PDF receipt with a shareable link and, because the patient is already enrolled in the automation, the reminder clock is recalculated based on the new dispense date.

5. Monitor reminders in real time

   • Open the Reminders board from the main navigation.
   • The board lists each scheduled reminder with columns for Patient, Medication, Scheduled Send, Status (Scheduled, Sent, Delivered, Read, Failed).
   • If a reminder fails (e.g., invalid phone number), the status turns red and a Retry button appears. Clicking it re‑queues the message and deducts another credit.

6. Review performance

   • Go to Reports → Messaging Effectiveness.
   • Filter the date range to the last 30 days and select the Chronic‑Care Refill Reminder automation.
   • The report shows:
     • 124 reminders sent
     • 98 delivered (79 %)
     • 62 read (50 %)
     • 45 patients confirmed a refill via WhatsApp (36 %)
     • $4,875 recovered revenue (including GST/HST, see CRA for exact rates)

Worked Example: Maple Leaf Pharmacy

Maple Leaf Pharmacy in Hamilton stocks a range of chronic‑care drugs. In July 2024 the owner, David Chen, notices that 12 % of his diabetic patients miss their 90‑day refill, leading to $2,300 of expired stock each quarter.

1. Setup – David imports 312 patient records via CSV and creates the Chronic‑Care Refill Reminder automation as described above. He tops up his Ferbz wallet with 5,000 credits (each WhatsApp reminder costs 1 credit).

2. First Sale – On July 15, patient Sonia Patel purchases 90 tablets of Metformin for $78 (including GST). The sale generates a receipt link and automatically enrolls Sonia in the reminder flow, scheduling a reminder for August 10 (5 days before the next due date).

3. Reminder Sent – On August 5, the reminder is sent from the official WhatsApp Business API. Sonia reads the message, replies ✅, and the branch logs a “Refill confirmed” event.

4. Follow‑up Sale – On August 7, Sonia returns to the counter. David rings up a New Sale for another 90 tablets, $78 again. The system updates Sonia’s next due date to November 10 and re‑calculates the next reminder.

5. Outcome – Over the next 60 days, Maple Leaf Pharmacy sends 58 reminders, receives 34 confirmations, and recovers $2,652 in revenue that would otherwise have been lost to expired stock. The Reminders board shows zero failed messages, and the Reports dashboard confirms a 28 % increase in refill adherence compared with the previous quarter.

Time saved – Before automation, David spent an average of 12 minutes per patient each evening calling or texting to check refill dates. With 312 chronic‑care patients, that equated to roughly 62 hours per month. After implementing Ferbz, the same task is handled automatically; the only manual step is reviewing the Reminders board, which takes about 15 minutes per week.

Revenue recovered – In the month before automation, Maple Leaf Pharmacy recorded $2,300 in expired stock for Metformin and Amlodipine. After two months of WhatsApp refill reminder automation, the pharmacy recaptured $2,652 in sales from patients who responded to the reminders. That is a net gain of $352 after deducting 58 credits (≈ $58) for the reminders themselves.

Fewer manual errors – Manual entry of due dates often led to mis‑calculations; the automation uses the exact dispense date and quantity to compute the next due date, eliminating human error.

Professional communication – Because messages are sent via the official WhatsApp Business API, they appear with the pharmacy’s verified business name and logo, increasing patient trust and compliance compared with personal‑number texts.

Compliance with Canadian tax rules – Each receipt generated at checkout includes the applicable GST/HST automatically, and the Reports module can export sales data for CRA filing, ensuring that the pharmacy remains audit‑ready without extra bookkeeping steps.

Overall, the combination of accurate scheduling, automated WhatsApp delivery, and real‑time monitoring translates into a measurable lift in patient retention, a reduction in wasted inventory, and a clear, credit‑based cost structure that aligns with the pharmacy’s cash flow.
