What This Is

Instant Visit Billing is the core Billing module of Ferbz, built especially for clinics and small hospitals that see sudden spikes in patient flow—whether it’s a seasonal flu wave in Lucknow, a dengue outbreak in Nagpur, or a local health‑camp that draws hundreds of walk‑ins in a single day. In Ferbz terminology a “Visit” is any encounter a patient has with your practice, from a routine consultation to a diagnostic test. When the front‑desk staff rings up a Visit against an existing Patient profile, Ferbz instantly creates a professional PDF receipt, uploads it to a secure link, and—crucially—triggers the Automation engine that starts the reminder clock without any extra clicks.

The workflow is completely self‑contained inside the Ferbz dashboard:

  1. New Sale – The staff selects the patient, adds services (consultation, lab test, minor procedure) and any medicines or consumables.
  2. Auto‑generated receipt – Ferbz builds a GST‑compliant PDF on the spot. Because clinical services are generally GST‑exempt, the receipt shows zero tax on the consultation line, while medicines (if any) are automatically tagged with the 12 % GST slab.
  3. Link sharing – The PDF link can be sent instantly via the official WhatsApp Business API (through Gupshup) or printed for the patient.
  4. Automation enrollment – The moment the receipt is generated, Ferbz enrolls the patient into any active automation journeys that depend on “Visit completed”. Typical journeys include a “Thank you + next‑appointment reminder” or a “Win‑back after 30 days”.
  5. Reminder clock – The trigger (e.g., “3 days after visit”) is calculated, and the corresponding WhatsApp message is queued. All credit consumption (reminder, broadcast, confirmation) is deducted from the prepaid wallet, so there is no hidden subscription fee.

In short, Instant Visit Billing does three things for a busy clinic: it removes the manual paperwork bottleneck at the front desk, it creates a digital receipt that can be shared instantly, and it hooks the visit into Ferbz’s automation engine so every patient automatically receives the right follow‑up message at the right time. The result is a seamless, end‑to‑end experience that turns a sudden surge of walk‑ins into a pipeline of loyal, return patients.

How Clinics and small hospitals Owners Use It

Below is a step‑by‑step narration of how a clinic owner—let’s call her Dr. Meera Sharma of Sunrise Health Centre in Bhopal—handles a viral surge of 78 walk‑in patients on a single afternoon using Ferbz.

1. Prepare the patient list (optional bulk import)

Before the surge, Dr. Sharma imports the day‑old registration CSV into the Patients module. She clicks Patients → Import CSV, maps columns (Name, Mobile, Age, Gender, Email) and hits Upload. All 78 patients now have a profile ready for billing.

2. Open the Billing screen

From the left navigation, Dr. Sharma selects Billing → New Sale. The screen shows a searchable patient dropdown, a service grid, and a “Add Medicine” button.

3. Ring up a Visit

For the first patient, Rohan Verma, she types “Rohan Verma” in the patient field, selects his profile, and the system auto‑populates his contact number (+91‑98765 43210). She then:

  • Chooses Consultation – General OPD (₹300, GST‑exempt).
  • Adds Blood Sugar Test (₹250, GST‑exempt).
  • Clicks Add Medicine → selects Paracetamol 500 mg – 10 tablets (₹45, GST 12 %).

The line items appear with correct tax calculations: ₹300 + ₹250 = ₹550 (no tax) and ₹45 + 12 % GST = ₹50.40, total ₹600.40.

4. Generate the receipt

She clicks Generate Receipt. Within 2 seconds Ferbz creates a PDF titled “Visit‑2024‑09‑09‑Rohan‑Verma.pdf”. The PDF shows:

  • Clinic name, address, GSTIN (if registered).
  • Patient details, Visit ID, date & time.
  • Itemised services with tax status.
  • Grand total ₹600.40.

A Shareable Link appears below the PDF preview: https://ferbz.com/receipt/abc123. The link is automatically copied to the clipboard.

5. Send the receipt via WhatsApp (official API)

Dr. Sharma clicks Send via WhatsApp. Ferbz uses the integrated Gupshup Business API to push the receipt link to Rohan’s mobile. The message reads:

“Dear Rohan, thank you for visiting Sunrise Health Centre. Your receipt is ready: [link]. Your next follow‑up is recommended in 7 days. – Dr. Meera”

The status bar on the Reminders board instantly shows SentDeliveredRead as Rohan opens the link.

6. Automation enrollment – “Post‑Visit Follow‑up” journey

Because the clinic has an active automation titled “Post‑Visit Follow‑up”, the moment the receipt is generated Ferbz enrolls Rohan. The journey is defined as:

  • Trigger: Visit completed → wait 3 days.
  • Message 1: “Hope you are feeling better, Rohan. Book your follow‑up now.” (WhatsApp button “Book Now” links to the Appointments calendar).
  • Branch: If no booking after 2 days → send reminder “We noticed you haven’t booked yet…”.

All messages use the clinic’s pre‑approved templates, editable on the visual canvas in Automation → Edit Journey.

7. Repeat for the remaining 77 patients

Dr. Sharma repeats steps 3‑5 for each patient. Because the UI is the same, each billing takes roughly 45 seconds. With 78 patients, the total front‑desk time is about 58 minutes, far less than the 4–5 hours it would take with paper receipts and manual phone calls.

8. Monitor the Reminders board

After the day ends, Dr. Sharma navigates to Reminders → Board. The board lists every scheduled follow‑up message, its current status, and any failures (e.g., invalid mobile number). She sees:

PatientTriggerScheduledStatus
Rohan Verma3 days post‑visit12‑Sep‑2024 10:00 AMSent → Delivered
Anita Rao3 days post‑visit12‑Sep‑2024 10:05 AMSent → Failed (invalid number)

Failed entries can be corrected instantly by editing the patient’s mobile number and re‑triggering the journey.

9. Review revenue and messaging effectiveness

From Reports → Revenue, Dr. Sharma selects the date range 09‑Sep‑2024 to 09‑Sep‑2024. The report shows:

  • Total Visits billed: 78
  • Gross revenue: ₹46,832.00 (including medicine GST)
  • Automated reminders sent: 78 (credits used: 78)
  • Follow‑up bookings generated (within 7 days): 22 (28 % conversion)

She can also view Automation → Journey Stats to see open‑rate, click‑through on the “Book Now” button, and overall ROI of the WhatsApp flow.

Full Worked Example – “Sunrise Health Centre”

Clinic: Sunrise Health Centre, Bhopal (Tier‑2 city)
Date: 9 September 2024 (post‑monsoon dengue surge)
Patients: 78 walk‑ins, average bill ₹600.40
Credits used: 78 reminder credits + 78 broadcast credits (receipt shares) = 156 credits
Cost: 156 credits × ₹0.99 ≈ ₹154.44 (rounded to nearest rupee)

Result: Dr. Sharma turned a chaotic surge into a structured revenue stream, saved ~4 hours of manual work, and secured 22 follow‑up appointments that would otherwise have been lost.

Why It Helps

  1. Time reduction – Traditional paper billing and manual phone confirmations can take 3–5 minutes per patient. With Ferbz, the end‑to‑end process (select patient, add services, generate receipt, send WhatsApp) averages 45 seconds. For a 78‑patient surge, the front desk saves ≈ 4 hours 30 minutes of staff time, allowing staff to focus on triage or clinical duties.

  2. Revenue protection – Each completed Visit automatically enrolls the patient in a follow‑up automation. In the Sunrise Health Centre example, 28 % of walk‑ins booked a return visit within a week, generating an additional ₹13,200 in projected revenue (average ₹600 per follow‑up). Without this automation, the clinic would have relied on ad‑hoc phone calls, which have a typical conversion of <10 %.

  3. Zero manual errors – GST calculations are handled by Ferbz. Clinical services stay GST‑exempt, medicines automatically pick up the 12 % slab. This eliminates the risk of tax‑non‑compliance penalties that small clinics often face when doing manual calculations.

  4. Transparent credit usage – Because Ferbz works on a prepaid wallet, Dr. Sharma sees exactly how many credits each reminder or receipt consumes on the Reminders board. There is no surprise monthly fee; the ₹154.44 spent on the surge is fully accounted for.

  5. Improved patient experience – Patients receive a professional PDF receipt instantly on WhatsApp, eliminating the need to wait for a printed copy. The follow‑up reminder arrives at the right moment, reducing no‑show rates. In a Tier‑2 city where many patients rely on mobile WhatsApp for communication, this aligns with local habits and builds trust.

Overall, Instant Visit Billing converts a chaotic influx of patients into a disciplined, revenue‑preserving workflow, while freeing staff from repetitive manual tasks and ensuring compliance with Indian GST rules.

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 (via Gupshup) using the single business‑level number you register in the platform. There is no QR‑code or personal‑number workaround.

02

How does Ferbz handle GST for medicines versus services?

A: When you add a line item, you select the appropriate tax slab. Clinical services (consultations, diagnostics) are marked GST‑exempt by default. Medicines and consumables are automatically assigned the standard 12 % GST slab, and the PDF receipt reflects the tax breakdown per line.

03

What happens if a patient’s mobile number is wrong and the reminder fails?

A: The **Reminders board** flags the entry as “Failed”. You can edit the patient’s contact details directly from the board, then click **Retry** to re‑queue the message. Credits are only deducted when a message is successfully sent.

04

Can I customize the follow‑up message that is sent after a Visit?

A: Yes. In **Automation → Edit Journey**, you can edit any message node on the visual canvas. Use your clinic’s approved WhatsApp templates, add buttons (e.g., “Book Now”), and preview before saving.

05

How do I know how many credits I will need for a busy day?

A: Each automated reminder, broadcast, and WhatsApp confirmation consumes one credit. Review the **Reports → Messaging** section to see average daily credit usage, then top up the prepaid wallet via Razorpay (₹99 = 100 credits, etc.) to cover expected volume. ---
