How to Split One Sale Across Cash, Card, Mobile Banking and Due

To split one sale across cash, card, mobile banking and Due without ledger confusion, record the full sale once in Tukri and assign each part of the payment to the correct money account or to the customer's due balance. That keeps the inventory movement, the sale total, and the unpaid amount tied to the same transaction instead of being scattered across a notebook, a card slip, and memory.

In a busy Bangladeshi shop, this problem is common. A customer buys goods worth ৳1,200, pays part in cash, sends part by mobile banking, and asks to keep the rest as বাকি (selling on credit, paid later). If you write the sale in one place, the mobile-banking amount somewhere else, and the due in a separate খাতা, end-of-day cash count stops matching. Shop owners commonly find the confusion starts not on big sales, but on ordinary mixed-payment bills.

What is the correct way to record a mixed payment sale?

The correct way to record a mixed payment sale is to make one bill for the full amount and then split the payment inside that same bill.

In Tukri's POS / quick billing flow, you can:

• add products by name, SKU or barcode
• apply per-line or whole-cart discounts
• split a payment across cash, card, bank, mobile-banking and Due
• save all of that under one sale record

That matters because each payment part has a different accounting meaning:

• Cash increases the cash account
• Card increases the card-related account you created
• Mobile banking increases the mobile-money account you created
• Due leaves the remaining balance under that customer

Tukri lets the owner create their own money accounts. Many shops name one account "bKash", "Nagad" or "Rocket" for convenience, but those are account labels for recording where money came in, not built-in payment-gateway integrations.

How do I record partial due sale without confusing the due ledger?

To record a partial due sale correctly, enter the amount received now and mark only the unpaid remainder as Due.

A simple example:

1. A customer buys items worth ৳2,000.
2. They pay ৳800 in cash.
3. They send ৳700 by mobile banking.
4. The remaining ৳500 stays as Due.

In Tukri, that is still one sale worth ৳2,000. The cash account gets ৳800, the mobile-money account gets ৳700, and the customer's due ledger gets ৳500.

This is where paper systems usually break down. In a notebook, many shopkeepers write the full sale in the cash memo, then separately write only the due amount in the বাকির খাতা. Later, when checking total sales against money received, the same sale can feel half-paid and half-missing. A digital due book avoids that because the due is linked to the original sale.

Tukri's বাকির খাতা / তালি খাতা keeps:

• a per-customer credit ledger
• sales-on-due and manual dues
• payment collections against dues
• a running "customers owe you ৳X" total
• SMS / WhatsApp due reminders or tap-to-call
• a downloadable customer statement PDF

So if a regular customer clears the remaining ৳500 at month-end, you collect against that due instead of creating a new sale or random cash entry.

How do I record mobile banking payment in a shop sale?

To record mobile banking payment properly, save that amount to a separate money account for the service the shop uses, then keep it inside the same sale as any cash or due amount.

For example, if a customer pays part by mobile wallet transfer, you can create a money account named "bKash" or "Nagad" and use it when taking payment. That helps with two practical problems:

• you can see how much money should be sitting in that account versus in the cash drawer
• you do not mix cash received with digital money received

At closing time in a small shop, this difference matters. Cash in hand can be counted. Mobile-money receipts cannot be counted from the till. If both are mixed in one handwritten total, the day's ledger becomes hard to trust.

Tukri also keeps one unified money-movement feed for cash, bank and mobile-money accounts, and balances are derived from transactions rather than edited by hand. That reduces the common habit of "adjusting" balances later to make the notebook match.

Paper khata vs split payment POS: where does confusion usually happen?

The confusion usually happens when one sale is broken into separate records instead of being saved once with multiple payment parts.

A paper notebook is still fine for a very new shop with very few credit customers and almost no mixed payments. But once you regularly see customers paying part now and part later, or part in cash and part by mobile banking, the manual method starts producing duplicate entries, forgotten balances, and arguments over what was already paid.

What steps should a small shop follow at the counter?

A small shop should follow one simple rule: finish the whole transaction before starting another, and record every amount inside the same sale.

Use this counter routine:

1. Create the bill once. Add all products to one cart.
2. Apply any discount before payment. Use line discount or whole-cart discount if needed.
3. Choose each payment part clearly. Enter the amount under cash, card, bank, mobile banking or Due.
4. Attach the customer if any amount is Due. This keeps the unpaid part under the right person.
5. Confirm the total equals the bill. Paid now plus Due should match the final sale amount.
6. Complete the sale once. Do not make a second entry for the due balance.

This is especially useful in clothing, electronics and pharmacy counters, where mixed payments happen often. A pharmacy may sell a box-based item by barcode and still leave a small amount on due. An electronics shop may take a down payment now and keep the balance as due if it is a regular credit sale; if it is a formal payment plan, Tukri's separate installment feature is the better fit than the due book.

How do I avoid ledger confusion at end of day?

To avoid ledger confusion at end of day, compare each money account to what should be there and keep due collections separate from new sales.

A practical closing checklist:

• count physical cash and compare it with the cash account
• check card and bank receipts against their recorded amounts
• check mobile-money collections against the mobile-money account total
• review new due created today
• review due collected today
• make sure no staff member recorded a payment twice

Tukri helps here because staff can sell and receive stock, while profit and settings stay restricted by role. The sale itself also works offline and syncs when back online, which matters in shops where internet is unreliable but billing cannot stop.

If your shop frequently deals with cash card due same sale situations, the main fix is not a more detailed notebook. It is one sale record that cleanly separates what was paid now from what is still owed.

If you are still using a paper ledger, keep it while the shop is tiny. But when mixed payments become a daily habit, try Tukri at tukri.bd and test a few real counter sales. You will usually know within a couple of busy days whether the confusion has dropped.
