Why No Registration is Not Always a Ticket to High Payment Approval Rates

Skipping registration step is one of the most popular tips for optimizing payments and checkout. It's usually recommended to mass-market products with a small ticket size and complex retention, such as eSIM, proxies, VPN, donations, or purchases of minor consumables. Behind this advice quite explainable arguments may be found: more people reach payment page, the funnel expands, no obstacles on the way to the payment. And given that the payment amount is expected to be small, there are many similar or identical services on the market selling the same product, every obstacle is a potential customer loss.

Although at first this sounds beneficial and even like "how did we not think of this ourselves?", this approach the other side, which is usually left unsaid. And today we will look at exactly that and discuss a certain disconnect in the perception of conversion metrics, which prevents a clear look at product results and measuring relevant indicators.

Checkout Conversion and Payment Approval Rate

First and foremost, it's important to understand which conversion you're actually measuring and how you understand effectiveness.

Checkout conversion and payment approval rate are two completely different metrics. Most guest checkout tests measure precisely the first one and stop at this solution as effective, having organically more payment attempts or people who reached payment page. However, even if more users reached the payment page, this does not always mean more profit for the company and a higher approval of payment.

Here one should not forget about the second metric, which will be based not simply on page visitors, but will account for the percentage of people who started placing an order and reached the point of attempting payment — that is, clicked “pay.” The number of successful purchases out of that volume is what will constitute the conversion of payment attempt into successful payment.

But this approach also needs to be balanced, since funnel expansion achieved by excluding registration on the website can accommodate more people, but the quality of these people will be significantly lower. Why is that?

Is a Barrier Needed?

First of all, registration is friction that is designed not only to collect marketing information, but also to identify the user as much as possible, to filter out invalid traffic, bots, and fraudsters. All these categories of users often don't spend time registering on the platform, since their task is to spend money or test payment credentials quickly. Where possible, they don't choose websites that require authorization, email verification, or IP address checks, since this unambiguously links them and their actions on the site, allowing them to be limited in the future. Using guest checkout is a gift for bad-faith customers, since each time they turn out to be new customers for the site and can exploit it for much longer before noticed.

Thus, by skipping registration and basic checks of visitors, a website creates an open door, and statistically, more people will indeed walk through it. However, there's no guarantee these will be honest payers and genuinely interested customers. One could object that a legitimate user also isn't eager to fill out a long registration form, and that's true. That's why here it's necessary to balance between product security and high metrics, run testing, and determine the appropriate option for a specific business, without fully abandoning barriers.

If there are no barriers at all, fraud metrics often reliably grow: the number of chargebacks and refunds, while approval rate doesn't always do so. It often happens that the result is achieved — more people at checkout — but approval is lower than with registration in place. In absolute numbers, successful payments may be comparable or even lower. This happens because a mass influx of uninterested customers simply blurs the picture and creates a deceptive appearance. The marketing department is happy that there are many leads on the site, and analytics even show that they're walking through the payment page and clicking on something, yet they aren't making the payment. Some of them may not even attempt it at all, simply scrolling through the page, while others do attempt it but don't complete it. Payment infrastructure often ends up being blamed in this situation, but much depends on the details of customer behavior. After thorough analysis, it becomes clearly visible which reasons for incomplete transactions prevail, how customers behaved before landing on the payment page, and how many times they'd visited the site.

What Monoup Conclude From Experience With Clients

Taking all this into account, implementing guest checkout or simplified registration can be justified in a number of cases, for example, for repeat customers or specific advertising campaigns. Do not forget to measure effectiveness across different customer categories: those who went through the full user path and those who skipped registration. And also, look not only at how many payments were accepted, but how many of them remained successful over time. Here the difference between guest checkout and mandatory registration is especially visible: the first figure may look attractive initially, but two or three months later, some of these payments come back as chargebacks or refunds.

Also, multi-step registration is indeed excessive for many products. In practice, there are partial solutions that preserve part of the effect without creating full-on friction at entry: email verification without instant confirmation, fingerprinting and IP reputation without user involvement, deferred registration after the first successful payment, varying levels of friction depending on the amount or payment method. This makes it possible to maintain high conversion for the legitimate majority while at the same time not opening the door for those who never intended to register, because their goal isn't a purchase, but testing credentials.

Ultimately, abandoning registration step isn't an optimization at all — it's a transfer of risk from the entry point to the point of payment, where responsibility shifts from marketing function to payments function. However, at this stage it only becomes more expensive: chargeback, rather than a checkout decline. In this regard, it's important to precisely understand which conversions a company needs to optimize, at what expense, and what effect this may have on other processes, since some figures may look good in reports but not in the bank account.
