Installment Payments on Your Website (PayU, Netopia): How to Enable Them

You sell products worth a few thousand lei, and you keep seeing carts abandoned right at the payment step. That's normal: a sofa, an e-bike, or a gaming laptop is hard to pay for in one shot. Installment payments directly on your site remove exactly that blocker — the customer sees an "in installments" option at checkout, picks the number of months, and finishes on the spot, no trip to the bank.

In Romania, the two processors that offer this are Netopia (formerly mobilPay) and PayU. In this article I'll explain how installments actually work, who pays the interest, which conditions you have to meet, and how to enable them step by step — no "guaranteed conversion" myths. At the end I'll tell you how we handle the technical side.

How installment payments actually work in Romania

Key thing to understand: in most cases installments don't come from the processor, they come from the bank that issued the customer's card. In practice these are "credit-card installments" — the customer pays with a credit card from a partner bank (BCR, BRD, Raiffeisen, Alpha Bank, Garanti, Unicredit and others), and the bank splits the amount into equal monthly payments.

That leads to a few rules:

• It works only with credit cards, not debit cards.
• The number of months available (usually 2 to 12) depends on each bank.
• There's often a minimum order value before the option appears.

Beyond credit-card installments, there's also point-of-sale financing (e.g. TBI Bank) and BNPL ("buy now, pay later") solutions — useful for customers who don't have a credit card.

Who pays the interest: you or the customer

This is the most important commercial decision. You have two options:

• Interest-free for the customer — you, the merchant, subsidise the interest. The bank keeps an extra commission from your revenue, but the customer sees "12 interest-free installments" and is far more likely to buy.
• Interest paid by the customer — you pay nothing extra, but the customer sees a higher total and the monthly cost may put them off.

Most stores selling expensive products choose "interest-free" over a limited number of months (say up to 6), because it's the strongest sales argument. Work out the extra commission and build it into your margin before enabling it — otherwise it eats your profit on every order.

Concrete steps to enable it with Netopia or PayU

The process is similar for both:

• You already have an account and an active payment-processing contract (verified store, IBAN, tax details).
• You request activation of the installments module from your merchant account or via a support request.
• You choose the partner banks you want to work with and the number of months.
• You decide who bears the interest and set the minimum order value.
• You sign the installments contract annex (those commissions are separate from standard-payment ones).

After approval, the "in installments" option appears automatically on the payment page hosted by the processor. You don't have to rebuild your checkout — but it's worth testing with a real credit card to see exactly what the customer sees.

The technical side: what needs to exist on the site

Good news: the processor handles the payment page, so you never touch card data. What's on your site's side:

• Correct integration with the Netopia or PayU API (or the official module if you're on WooCommerce, PrestaShop, etc.).
• Sending the amount and currency correctly, plus handling the confirmation response (IPN / server-to-server notification), so you only mark an order as paid once the bank confirms.
• Clearly showing the installments option on the product page, not just at the end — a small "available in installments" line next to the price builds trust.
• Testing on mobile, where most orders are lost.

If the integration is done badly, you get the classic result: the customer pays, but the order stays "pending". That's why server-to-server confirmation has to be handled carefully.

How we approach it at MPO Web Studio

We build premium websites for local businesses and deliver fully remote, nationwide. For stores that want installment payments, we integrate Netopia or PayU straight into checkout, with server-to-server confirmation handled correctly, and we surface the installments option right on the product page.

Before we work together, we build you a free demo of your site, so you can see exactly how it looks and how the order flow works before paying anything. Transparent pricing, no hidden costs.

One honest warning: nobody can "guarantee" a sales increase. Installments reduce payment friction — but the right price, good photos, and trust in your store matter too. If you want to talk specifics, message us on WhatsApp and we'll tell you what fits your products.
