What This Is

Instant visit billing for clinics is the core Billing workflow inside Ferbz that lets front‑desk staff ring up a patient’s visit, generate a PDF receipt with a shareable link, and automatically kick‑off the WhatsApp reminder engine – all in a single click.

When a patient walks into a small‑clinic or a tier‑2‑city hospital, the receptionist selects the patient’s record from the Patients CRM, adds the services rendered (consultation, lab test, minor procedure, etc.), and clicks New Sale. Ferbz instantly creates a Visit entry, calculates the total amount, and produces a downloadable PDF receipt that can be emailed, printed, or sent as a WhatsApp link to the patient. The moment the receipt is generated, Ferbz records the visit as completed and evaluates every active Automation flow that is triggered by “visit completes”. If a reminder journey is configured – for example, “send a follow‑up appointment reminder 2 days after the visit” – the system enrolls the patient, sets the reminder clock, and queues the first WhatsApp message.

All messaging is sent through the official WhatsApp Business API (via Gupshup), so the clinic never relies on a personal number or QR‑code workaround. The Reminders board shows the status of each reminder (scheduled, sent, delivered, read, or failed) in real time, while the Reports module captures revenue from that visit and the effectiveness of the subsequent reminder (open rates, click‑throughs, re‑bookings).

Because Ferbz runs on a prepaid credit wallet, each generated receipt does not cost credits, but every automated reminder, broadcast, or booking confirmation draws from the balance. Clinics therefore pay only for the messages they actually send, avoiding a fixed monthly subscription. The entire flow – from billing to reminder – is designed for appointment‑driven practices that need a fast, error‑free front‑desk experience without juggling separate billing software, inventory sheets, and manual phone calls.

How Clinics and small hospitals Owners Use It

Below is a step‑by‑step narration of how a clinic owner or front‑desk manager would use the instant visit billing capability in a typical day. Imagine Aarav’s Family Care, a 12‑bed clinic in Bhopal that offers general consultations, blood‑test diagnostics, and minor procedures such as wound dressing.

  1. Log in to the Ferbz dashboard
    Open a browser, go to https://dashboard.ferbz.com/, and sign in with your admin credentials. The home screen shows the main navigation bar on the left: Dashboard, Patients, Billing, Appointments, Doctors, Automation, Broadcasts, Reminders, Reports.

  2. Select the patient
    Click PatientsAll Patients. Use the search bar to type “Rohit Sharma”. The patient card appears with his contact number, age, and a timeline of past visits. Click the card to open Rohit’s profile.

  3. Create a new visit (billing)
    Inside Rohit’s profile, hit the New Sale button at the top right. A modal titled Create Visit opens.

    • Service type: Choose Consultation (₹500) and Complete Blood Count (₹350).
    • Quantity: 1 each.
    • Discount: Apply a 5 % senior citizen discount if applicable.
    • Tax: The system automatically marks the consultation as GST‑exempt and the lab test at 12 % GST (standard medicine slab).
    • Total: ₹500 + ₹350 + 12 % GST on ₹350 = ₹892 (rounded).

    Click Generate Receipt. Ferbz instantly creates a PDF receipt named Visit_2024-09-12_RohitSharma.pdf and shows a Shareable Link button. The link can be copied to the clipboard or sent directly via WhatsApp from the same screen.

  4. Send the receipt (optional)
    If the clinic prefers to email the receipt, click Email and type Rohit’s email address; Ferbz sends the PDF automatically. For WhatsApp, click WhatsApp → the system uses the official WhatsApp Business API to push the receipt link to Rohit’s number. The message reads:

    “Dear Rohit, thank you for visiting Aarav’s Family Care on 12 Sept 2024. Your receipt is here: link. Please keep it for your records.”

    The moment the receipt is sent, Ferbz marks the visit as completed.

  5. Automation enrollment
    Because the clinic has an automation flow titled “Post‑Visit Follow‑up” (created under AutomationJourneys), Ferbz evaluates the trigger “when a visit completes”. The flow’s first step is a wait of 2 days, then a WhatsApp message:

    “Hi Rohit, hope you’re feeling better. It’s time for your next follow‑up visit. Book an appointment here: booking link.”

    The system automatically enrolls Rohit, sets the reminder clock for 2 days later, and shows the pending reminder on the Reminders board under the Scheduled tab.

  6. Confirm the reminder on the board
    Click RemindersBoard. You’ll see a row:

    • Patient: Rohit Sharma
    • Visit ID: V‑20240912‑001
    • Trigger: 2 days after visit
    • Status: Scheduled (00:00:00)

    This live view lets the clinic manager verify that no reminder is silently failing.

  7. If the patient books again
    Suppose Rohit clicks the booking link and selects 15 Sept 2024 at 10 am. The Appointments calendar instantly creates a slot, sends an automatic WhatsApp confirmation (“Your appointment is confirmed for 15 Sept 2024, 10 am”), and links the appointment to Dr. Meena (the doctor assigned to follow‑ups). The new appointment also appears on the Reminders board as a Booking Confirmation reminder, consuming one credit from the prepaid wallet.

  8. Review the outcome
    After the follow‑up reminder is sent, the Reports module can be filtered by AutomationPost‑Visit Follow‑up to see:

    • Sent: 1, Delivered: 1, Read: 1
    • Re‑bookings: 1 (Rohit booked the follow‑up)
    • Revenue uplift: ₹892 from the original visit + ₹500 from the follow‑up consultation = ₹1,392

    The clinic can see the exact credit cost (1 credit for the reminder, 1 credit for the booking confirmation) and compare it to the additional ₹500 earned.

  9. Repeat for next patient
    The same workflow repeats for every patient that walks in. Because the steps are confined to a few clicks inside Ferbz, front‑desk staff spend less than 30 seconds per patient on billing and reminder setup, compared with the previous manual process of printing a receipt, calling the patient, and noting the reminder in a notebook.

Full worked example – numbers

  • Clinic: Aarav’s Family Care, Bhopal

  • Day: 12 Sept 2024

  • Patient: Rohit Sharma, 58 y/o

  • Services: Consultation (₹500, GST‑exempt) + CBC test (₹350, 12 % GST)

  • Discount: 5 % senior citizen on total before tax → ₹42.5 discount

  • Tax: 12 % of ₹350 = ₹42

  • Final amount: (₹500 + ₹350 – ₹42.5) + ₹42 = ₹849.5 ≈ ₹850 (rounded)

  • Credits used:

    • 1 credit for the post‑visit reminder (sent 2 days later)
    • 1 credit for the booking confirmation WhatsApp message
  • Revenue impact:

    • Original visit revenue: ₹850 (GST‑exempt for consultation, 12 % GST on test)
    • Follow‑up visit booked via reminder: ₹500 (consultation)
    • Total incremental revenue: ₹500 for 2 credits → ₹250 per credit ROI

The clinic can see this ROI instantly in the Reports tab, reinforcing the value of instant visit billing combined with automated WhatsApp reminders.

Why It Helps

Time saved – Before Ferbz, a receptionist had to: (1) manually calculate taxes, (2) write a paper receipt, (3) scan or email it, (4) pick up the phone, and (5) call the patient to confirm the next appointment. That typical sequence took 3–4 minutes per patient. With instant visit billing, the same sequence completes in under 30 seconds, a reduction of ≈85 % in front‑desk processing time.

Revenue recovered – In a clinic that sees 20 patients a day, a 2‑minute manual follow‑up call per patient translates to 40 minutes lost and often results in missed reminders. Ferbz’s automation ensures every visit triggers a reminder without human intervention. In our worked example, the reminder generated a ₹500 follow‑up consultation that would otherwise have been lost. Across 20 patients, assuming a conservative 15 % conversion from reminders to re‑bookings, the clinic can earn an extra ₹1,500 – ₹2,000 per day while spending only 2 credits (≈₹2).

Error reduction – Manual tax calculation can lead to compliance issues, especially with the 12 % GST on medicines and consumables. Ferbz applies the correct GST slab automatically, ensuring the clinic remains GST‑exempt for services and compliant for consumables.

Visibility and control – The Reminders board gives a live snapshot of every scheduled, sent, or failed message. If a reminder fails (e.g., due to an invalid number), the status changes to Failed and the clinic can instantly re‑send, preventing silent drop‑offs.

Cash‑flow friendly pricing – Because credits are purchased only when messages are sent, a tier‑2 clinic that sends 150 reminders a month spends ₹150 – ₹300 (depending on credit pack) instead of a fixed ₹2,000‑₹5,000 monthly SaaS fee. This aligns cost with actual usage and makes budgeting predictable for small‑practice owners.

Overall, instant visit billing removes the bottleneck at the front desk, guarantees that every patient receives a timely WhatsApp reminder, and translates directly into measurable revenue uplift and operational efficiency.

Questions you may have
01

Do I need a separate WhatsApp number for each clinic location?

A: No. Ferbz sends all messages through the official WhatsApp Business API managed by Gupshup. You only need one verified business account; the API handles delivery to all patient numbers.

02

What happens if a patient’s phone number is wrong or the message fails?

A: The reminder appears as *Failed* on the **Reminders board**. You can click the entry, edit the phone number, and re‑send the message—all within the same dashboard.

03

Are GST calculations automatic for medicines versus services?

A: Yes. When you add a line item in the **New Sale** screen, Ferbz flags it as a service (GST‑exempt) or a medicine/consumable (12 % GST by default). You can override the tax slab per line item if needed.

04

How many credits does a single reminder consume?

A: Each WhatsApp message—whether it’s a receipt link, a booking confirmation, or an automation reminder—uses **1 credit**. Broadcasts that send the same template to many patients still consume 1 credit per recipient.

05

Can I edit the reminder message after the automation flow is created?

A: Absolutely. Go to **Automation** → **Journeys**, select the flow, and click the message node on the visual canvas. You can modify the text, insert patient variables, or change the template, then save. The next time the flow runs, it uses the updated content. ---
