What This Is
Fast counter billing with Ferbz is the Billing module working hand‑in‑hand with the Patients and Automation modules to turn every in‑store sale into an instant, paper‑free receipt and a live refill‑reminder workflow. When a pharmacy staff member rings up a sale against an existing patient, Ferbz automatically creates a PDF receipt, stores it in the patient’s profile and publishes a shareable link that can be sent via WhatsApp in a single click. The moment the receipt is generated, the reminder clock starts ticking according to the automation flow you have defined – for example “send a refill reminder 7 days before the next Metformin pack is due”.
All of this happens inside one dashboard, so there is no need to juggle a separate point‑of‑sale (POS) system, a stand‑alone invoicing app, and a third‑party messaging tool. The Billing screen lets you select a patient (or create a new one on the fly), add the items being purchased – Metformin 500 mg tablets, Amlodipine 5 mg tablets, insulin pens, vitamin C sachets – and apply any applicable VAT as required by HMRC. When you click Complete Sale, Ferbz instantly:
- Generates a PDF receipt that complies with UK tax rules and stores it under the patient’s record.
- Adds the sale to the patient’s purchase history, visible on the Patients tab.
- Triggers any automation journeys that are listening for “sale completed” – for example a refill‑reminder workflow that will calculate the next due date and schedule a WhatsApp message through the official WhatsApp Business API.
Because Ferbz runs on a prepaid credit wallet, each reminder, broadcast or confirmation that is sent draws from your credit balance – there is no hidden monthly fee, and you only pay for the messages you actually send. The Reminders board shows the status of every scheduled reminder (pending, sent, delivered, read or failed) so you can be certain that no patient is left behind.
In short, fast counter billing with Ferbz means a pharmacy can keep the checkout line moving, capture every sale in a compliant record, and automatically start the refill‑reminder journey without any manual data entry after the sale is complete.
How Independent Pharmacy Owners Use It
Below is a step‑by‑step walkthrough of using the fast counter billing capability in a typical independent pharmacy – let’s call it Greenfield Pharmacy on the High Street in York. The example uses realistic numbers and shows how a single sale creates a refill reminder for a chronic‑care patient.
1. Log into the Ferbz dashboard
Open a web browser, go to https://dashboard.ferbz.com/ and sign in with your credentials. The home screen displays the main navigation bar on the left: Dashboard, Billing, Patients, Automation, Broadcasts, Reminders board, Reports.
2. Select the Billing tab
Click Billing. The screen shows a clean “New Sale” form with three sections:
- Patient – a searchable dropdown.
- Items – a table where you add product lines.
- Summary – totals, VAT, and the Complete Sale button.
3. Choose the patient
In the Patient field type “John Smith”. Ferbz pulls up John’s existing profile (John is a 58‑year‑old with hypertension and type‑2 diabetes). If the patient were new, you could click Add new patient and fill in name, mobile number, address and NHS number – all of which will be stored for future reminders.
4. Add the items being purchased
Click Add line and start typing “Metformin 500 mg”. Select the product, enter the quantity (2 packs), and the system auto‑populates the unit price (£4.20 per pack). Repeat for “Amlodipine 5 mg” (1 pack, £3.10) and “Vitamin D 1000 IU” (1 bottle, £5.50).
The Summary area now shows:
- Sub‑total: £16.80
- VAT (calculated according to HMRC rules for medicines – generally zero‑rated for prescription items, standard‑rated for over‑the‑counter supplements): £0.00 for the prescription items, £1.10 for the vitamin supplement.
- Total: £17.90
5. Complete the sale
Press Complete Sale. Ferbz instantly does three things:
- PDF receipt – a downloadable PDF appears with a unique link (e.g.,
https://ferbz.com/receipt/AB12CD34). The receipt lists each line item, quantities, prices, VAT breakdown and the total. - Patient record update – John’s profile now shows this sale under the “Purchase history” tab, with the date, items and total amount.
- Automation trigger – because the Automation module has a journey titled “Metformin refill reminder – 7 days before due”, Ferbz enrolls John into that journey at the moment the sale is saved.
6. Send the receipt via WhatsApp (optional)
Navigate to the Patients tab, open John’s profile, and click Send receipt. A pre‑filled WhatsApp message appears, using the official WhatsApp Business API via Gupshup. The message reads:
“Hi John, thanks for picking up your Metformin and Amlodipine today. Your receipt is here: [link]. If you have any questions, reply to this chat.”
Hit Send. One credit is deducted from your wallet for the outgoing message. The status (sent/delivered/read) will appear on the Reminders board under the “WhatsApp messages” section.
7. Verify the reminder is scheduled
Open the Reminders board from the left navigation. You will see a new entry:
| Patient | Reminder type | Trigger | Scheduled for | Status |
|---|---|---|---|---|
| John Smith | Metformin refill | 7 days before next pack due (calculated from sale date) | 2024‑10‑05 09:00 GMT | Pending |
The reminder is automatically calculated: John bought 2 packs of Metformin, each covering 30 days. The system adds 60 days to today’s date (2024‑08‑06) and subtracts the 7‑day lead time, resulting in the 5 October send date.
8. Review the automation flow (optional)
If you want to see or edit the journey, click Automation → select “Metformin refill reminder – 7 days before due”. The visual canvas shows:
- Trigger: “Sale completed” + product = Metformin → Wait 53 days → Message (WhatsApp template “Refill reminder”) → Branch (if patient replies “Yes”, create a new sale; if “No”, send follow‑up in 3 days).
All templates use your pharmacy’s branding and can be edited directly on the canvas.
9. End of day – check reports
At any time, go to Reports → select “Sales & Messaging” for the date range 2024‑08‑01 to 2024‑08‑06. The report shows:
- Total sales: £1,274.60
- Number of receipts sent via WhatsApp: 27 (credits used: 27)
- Reminders scheduled: 22, of which 20 have been delivered and 2 are pending (e.g., a patient who purchased a 90‑day supply).
This gives you a clear picture of revenue, messaging spend and reminder effectiveness without leaving the Ferbz dashboard.
Why It Helps
Speed at the counter – In the example above, the entire checkout process took under 90 seconds from selecting the patient to printing the receipt link. There is no need to manually write down the next refill date or to copy‑paste patient details into a separate reminder system.
Reduced manual errors – Because the sale automatically populates the patient’s purchase history, the refill‑reminder date is calculated by the system, eliminating the common mistake of mis‑reading a prescription label or forgetting to note a 30‑day supply.
Revenue protection – Prior to using Ferbz, Greenfield Pharmacy lost an estimated £12.40 per month on missed insulin refills for just five chronic patients who forgot to return. After implementing fast counter billing, the automated reminder journey nudged 4 of those patients back within the 7‑day window, recovering £9.80 in sales and preventing the insulin from sitting idle on the shelf.
Credit‑controlled messaging cost – With the prepaid wallet, Greenfield Pharmacy spent exactly 27 credits on receipt messages and 22 credits on refill reminders for the week, a transparent spend of £0.27 + £0.22 (assuming the agreed credit value). There is no surprise monthly bill; you top up only when you need to send more messages.
Better stock turnover – By ensuring patients receive timely refill prompts, the pharmacy reduces the chance that a 30‑day pack of Metformin expires on the shelf. In the first month of use, expired stock fell from £45.30 to £12.70, a £32.60 improvement directly linked to higher refill adherence.
Overall, fast counter billing with Ferbz turns a routine checkout into a revenue‑protecting, compliance‑friendly, and fully automated workflow that keeps the pharmacy moving quickly while safeguarding chronic‑care income streams.

Do I need a separate POS system to use Ferbz billing?
A: No. Ferbz’s Billing module replaces a traditional POS for counter‑driven pharmacies. All sales, receipt generation and patient linking happen inside the Ferbz dashboard.
What happens if a patient pays cash and does not have a mobile number?
A: You can still complete the sale and generate a PDF receipt. The receipt link can be printed or handed to the patient. If a mobile number is later added to the patient’s profile, future reminders will be sent automatically.
Can I customise the WhatsApp reminder message that is sent after a sale?
A: Yes. In the Automation canvas you can edit the WhatsApp template used in each journey. The message can include your pharmacy’s name, opening hours and a direct link to the receipt or a booking page.
How does Ferbz calculate the “days until due” for a refill reminder?
A: The system uses the quantity and dosage information entered for the product line (e.g., 2 packs of Metformin 500 mg, each covering 30 days). It adds the total coverage days to the sale date, then subtracts the lead‑time you set in the automation trigger (e.g., 7 days).
What if a reminder fails to send – will I be charged?
A: Credits are deducted only when a message is successfully handed to the WhatsApp Business API. Failed deliveries appear on the Reminders board with a “Failed” status, allowing you to retry or investigate without additional cost. ---
