Running a pharmacy or medical store often involves more than selling medicines. Some regular customers may ask to buy medicines on Udhar (credit) and pay later. The real challenge begins when the customer does not pay the full amount at once.
A bill may be partially paid today, another amount may be paid next week, and the remaining balance may stay outstanding for several days. If these payments are recorded in a notebook, loose paper, WhatsApp messages or memory, it becomes easy to lose track of the original bill and the amount still owed.
For pharmacy owners in Pakistan, a clear pharmacy Udhar management workflow can make this process easier. The goal is simple: keep every credit sale connected to its original bill, record every payment and know the remaining balance at any time.
What is pharmacy Udhar management?
Pharmacy Udhar management means keeping an organized record of medicines sold on credit and the payments made against those sales.
Instead of treating every payment as a separate transaction, the payment remains connected to the original bill. This makes it possible to see:
- The total amount of the bill
- How much the customer has paid
- How much remains
- The bill’s current status
- Previous installment payments
- Payment dates, methods and notes
- Customer information such as name and phone number
- The due date
This approach is particularly useful when customers pay their pharmacy credit in multiple installments.
A step-by-step pharmacy Udhar workflow
1. Create the original bill
Create the customer’s pharmacy bill normally. If the customer is purchasing medicines on credit, keep the Udhar record associated with that original bill. Every future payment must connect to the correct transaction.
Store the relevant customer details, including the customer’s name and phone number, along with the due date where applicable.
2. Record the opening payment
A customer may pay part of the bill immediately instead of taking the entire amount on credit. If the bill is Rs. 5,000 and the customer pays Rs. 2,000 at the time of purchase, record that opening payment against the bill.
The bill is partially paid because Rs. 3,000 remains outstanding.
3. Track the remaining balance
Once the opening payment is recorded, the owner should be able to identify how much remains unpaid. Maintain this calculation against the original bill instead of manually creating a new record whenever the customer pays.
Remaining balance = Original bill total − Total payments
4. Add later installments
The same customer might later pay Rs. 1,000 and then another Rs. 1,000. All three payments still belong to the same Rs. 5,000 bill.
5. Record useful payment details
Every later installment should retain enough information to be reviewed. A proper payment history records:
- Date
- Amount
- Payment method
- Relevant note
This creates a clearer record than writing only “paid Rs. 1,000” in a notebook. The owner can later see when the payment was recorded, how much was paid and which method was used.
6. Monitor bill status
A credit bill can have different statuses depending on its payment condition:
The complete bill amount has been paid.
Some amount has been paid, but a balance remains.
The bill has not been paid.
The due date has passed while a balance remains.
Common pharmacy Udhar record-keeping mistakes
Recording payments without the original bill
If an installment is recorded separately, it becomes difficult to determine which credit sale the payment belongs to.
Forgetting small partial payments
A customer may pay Rs. 500 or Rs. 1,000 and the owner may remember the payment but forget to update the remaining balance.
Creating a new bill for every installment
Later payments are not new sales. Keeping installments associated with the original bill provides a clearer history.
Saving too little payment information
Without the date, amount, method and note, it can be difficult to review what happened later.
Not verifying customer details
Incorrect customer names or phone numbers make it harder to identify the correct person. Verify customer and payment information before saving records.
Relying entirely on memory
A busy pharmacy handles many customers and transactions. Depending on memory increases the chance of mistakes.
Customer reminders for outstanding Udhar
Customer information such as the name, phone number and due date gives the owner what is needed to follow up about an outstanding amount.
Before contacting the customer, check the original bill and complete payment history. This helps ensure the reminder reflects the actual outstanding balance.
MedStock Pro does not automatically collect money. The pharmacy owner or authorized staff remains responsible for contacting the customer, confirming payments and recording them accurately.
