What if a customer says they've paid via an app but the money hasn't arrived?

Never hand over the product until you see the incoming payment notification on your own phone or banking app. The customer's receipt is not enough: it may be pending or sent to the wrong number. Always confirm the amount and reference before handing anything over.

Accepting mobile payments in your shop: a practical guide

Q: Is it worth accepting mobile payments in a small shop?

Yes. Mobile payment is fast, avoids the change problem and is used by more and more customers, especially younger ones. With contactless (Apple Pay, Google Pay) you don't have to do anything special if your terminal already takes contactless cards, and instant-payment apps usually credit the money to your account straight away.

Q: How do I reconcile mobile payments at the end of the day?

Record each payment by its method in your POS: cash, card (including Apple Pay and Google Pay, which go through the terminal) or instant-payment app (which goes to your bank account). When you close the till, the system gives you the total per method and you compare it with your bank and your terminal. That way everything balances.

More and more customers walk into your shop without a wallet — just their phone or watch. They ask for the bread, the drink or the detergent and pay by tapping the phone. If you don't accept mobile payments, some of them will spend less or go somewhere else. It's not a fancy extra: it speeds up the till, gets rid of the change problem and stops you losing sales. Here's why it's worth it and how to fit it into your day without any hassle.

Why accept mobile payments in your shop

Paying by phone is no longer just for very tech-savvy people. Today it's normal in any local shop, and here's why offering it pays off:

It speeds up the till. A mobile payment is done in seconds. No hunting for coins, counting notes or getting change wrong in a rush.
Goodbye change problem. How many times have you had to ask "any smaller change?" or run out of coins by mid-morning. With the phone, the amount is always exact.
Younger customers love it. Lots of people barely carry cash anymore. If you don't accept their usual payment method, they'll spend less or shop elsewhere.
Instant collection. Contactless is a single tap, and some instant-payment apps credit the money to your account straight away.
Less cash in the drawer. Less physical cash means less risk, fewer trips to the bank and fewer discrepancies.

And there's one quieter but important reason: it makes your shop look up to date. A customer who sees you accept mobile payments perceives a business that has modernised, and that builds trust.

What kinds of mobile payment exist

They're not all the same. It helps to tell apart two big families, because they work differently at your counter.

Contactless wallets: Apple Pay, Google Pay and contactless cards

This is the most universal one. The customer keeps their card stored in their phone or watch and pays by tapping it on the terminal, without pulling out the physical card. For you it's exactly like taking a contactless card payment — in fact it goes through your same terminal with the same fees — but for the customer it's faster and easier. You don't have to do anything special: if your terminal accepts contactless, you already accept Apple Pay and Google Pay. This works the same in any country.

Instant-payment apps (depending on the country)

Alongside wallets, many countries have apps to pay account to account by entering a phone number or scanning a QR, with the money transferred instantly. In Spain the most widespread is Bizum (there's a personal version and also a business version with a QR and an identified deposit). In Portugal, the common equivalent is MB WAY. If you have customers from other countries or you're near a border, it's worth knowing which one people use in your area.

Key idea: wallets (Apple Pay, Google Pay) are cards inside the phone and go through your terminal. Instant-payment apps go account to account and do NOT go through the terminal. Understanding this helps you balance the till, because each one comes in through a different channel.

How to take mobile payments day to day

Offering mobile payments is easy, but so it doesn't get muddled when you're busy, it helps to have a clear method. Here's the step-by-step:

Keep the terminal handy and, if you use an app, a visible QR

For contactless, the customer just taps the phone on the terminal. If you also accept an instant-payment app, a small sign with your QR saves dictating your phone number on every sale.

Say the amount out loud and clearly

"That's 7.40." With contactless the amount is already keyed into the terminal; with an app, having the customer enter the right amount avoids underpayments.

Confirm the payment before handing over

With card/contactless, wait for the terminal's "approved". With an app, the golden rule: don't hand over the product until YOU see the incoming payment notification. The customer's screen is no proof.

Record the sale in the POS with its payment method

Mark whether it was card (including Apple Pay/Google Pay) or a payment app. That way it's counted just like cash and when you close the till everything balances.

Don't mix methods "to go faster"

Every sale, its own method. Logging everything as "cash" to save time is exactly what breaks the balance at the end of the day.

How to reconcile mobile payments in the till

This is the point that causes the most headaches and where most people get it wrong. If you take a payment via an app but then count it as if it were cash, your till will never balance, because that money is in your bank account, not in the drawer.

The right way is to treat each method as its own payment method. When you record the sale, you note how it was paid. At the end of the day:

The cash in the drawer should match only your cash sales plus the opening float.
The card total (including Apple Pay and Google Pay) should match your terminal's settlement.
The instant-payment apps total should match the deposits you see in your bank account.

If you split by method from the start, balancing is a breeze. If you mix it all together, you'll spend the night chasing a discrepancy that doesn't exist. A POS that splits the close by payment method does this job for you.

Best practices (and mistakes to avoid)

Don't treat it as paid without confirming. The costliest mistake. With an app, wait for your incoming-payment notification; the customer's receipt may be pending, cancelled or sent to another number.

Don't count app payments as cash. That money isn't in the drawer. If you mix it in, your till will never balance.

Don't force an unfair minimum. Posting "mobile only from €10" annoys customers. For small amounts, mobile payment usually works out the same or better than refusing it.

Don't dictate your number from memory in a rush. If you take app payments, one wrong digit and the money goes to someone else. Always use the QR.

Don't leave the terminal outdated. To accept Apple Pay and Google Pay you need contactless active. If your terminal is very old, replace it.
