Most entrepreneurs choose a payment partner based on the most obvious metric–price. In payments, that means the fee. And very often, this is exactly where they end up losing more than they save. This isn’t an exaggeration, it’s a pattern I’ve seen for years.

A business owner opens a comparison table, looks at fees, picks the lowest one and thinks: “Great, done.” Then wonders why funds are delayed, customers drop off before completing payment, and the accountant quietly hates every process.

Because in reality, a payment partner is not just about the question “how many percent.” It’s part of your business model. And the right choice can increase conversion, save you weeks of time, and reduce the kind of stress better spent on growing your business. Here are three key criteria to focus on.

1. Look at total economics, not just the fee

Globally, the average cart abandonment rate in e-commerce is around 70%. That means 7 out of 10 customers who add items to their cart never complete the purchase. One of the main reasons is a complicated, unclear, or untrustworthy payment experience.

Let’s do simple math: if your online store makes 100 sales per month, and your conversion improves by just 2% thanks to a better payment experience, that means two extra sales per month, 24 per year. With an average order value of €30 (approx. 1,300 UAH), that’s €720 in additional annual revenue. Now try to find a fee difference that outweighs that.

Another often overlooked factor is settlement speed. The difference between “same-day” and “2–3 business days” is not a technical detail, it’s your cash flow. It directly impacts how fast you can reinvest and grow.

Takeaway: consider the full picture: fee + settlement speed + impact on conversion.

2. Choose infrastructure, not just a service

In 2025, Ukraine’s e-commerce market reached 256 billion UAH, growing by 7% year-over-year. As the market grows, so does operational complexity: more orders, more payments, more reporting.

Small businesses spend up to 30–40% of their time on operational tasks–manual data entry, reconciliation, invoicing, compliance. That’s not business, that’s process maintenance. The more tools you use across different systems, the more errors and inefficiencies you create.

What should be in one place: business account; payment acceptance and acquiring; invoicing; CRM and marketplace integrations; automated fiscalisation.

Takeaway: your payment partner should simplify your business, not add another dashboard, login, or report.

3. Think from the customer’s perspective

Here’s a fact often underestimated: lack of preferred payment methods is one of the main reasons customers abandon their carts.

In Ukraine, this is especially visible. A large share of customers still prefers cash on delivery–not because they don’t have cards, but because they want to see the product before paying. It’s about trust, not technology.

Another trend: In 2025–2026, installment payments and buy-now-pay-later options have become standard in e-commerce – not just for expensive goods, but for everyday purchases.

And the simplest rule: the fewer steps between “I want it” and “I paid,” the higher your conversion. Optimizing the checkout process can increase conversion by up to 35%. This isn’t magic, it’s the math of convenience.

Takeaway: a strong payment partner increases conversion, not just processes transactions. And it builds customer loyalty.

Instead of a conclusion–three simple questions

Before choosing a payment partner, ask yourself:

  • Am I evaluating total economics or just the fee?
  • Does this simplify my business or add complexity?
  • Is it easy for my customers to pay?

If the answer is “yes” to all three–you’re on the right track. Because today, a payment partner is not a cost. It’s one of the drivers of your business growth.
