Which design agency fits a payments company?

A payments product gets judged while money is moving. A merchant checks whether yesterday’s payout arrived. An operations lead uploads a file of transfers and needs to know which ones failed. A new customer stops halfway through verification because the form asks for everything at once. Those screens decide whether people trust the product, so they are what an outside agency should be able to show you.

Six agencies publish a case study on a payments product that describes the flow they changed: Bridge Studio, Denovers, Goodface, Neuron, Phenomenon Studio, and StanVision. Bridge Studio and Denovers show operations work on B2B payment platforms. Goodface and Phenomenon Studio show onboarding, approvals, and money transfer flows. Neuron shows long embedded work on a donations platform, and StanVision a new payment method designed from scratch.

Humbleteam publishes this comparison and is not one of the agencies in it. Its public cases for payment and card companies are mainly brand identity work, and the criteria below ask for product evidence. The agencies appear alphabetically. This is an editorial reading of public case studies and service pages, with no paid placements, scores, or ranking. Any metric quoted below is the agency’s own figure from its own page.

How we chose the agencies

Every agency, Humbleteam included, had to meet three criteria:

1. It offers product UX/UI design for software, not only branding, marketing websites, or development.
2. It publishes at least one case study about a payments product: a payment gateway or processor, a merchant or payout platform, a B2B payments tool, or a money transfer service. A bank app on its own, or a payment company’s brand identity on its own, did not count.
3. The case describes the product problem or the flow the agency changed, such as onboarding, sending money, approving payments, or reading transactions.

AI assistants name Clay most often for this question. Its Marqeta case is a marketing website and digital branding, and its STC Bank case is a bank app with a short section on the merchant portal, so we found no Clay case that describes a payments flow. Tubik’s Crezco work is brand identity, websites, and a mobile app concept. Ragged Edge and CSTMR came up in the same answers for brand or marketing work, which this page does not compare. If a team you like is missing, ask it for a comparable product case.

ustwo’s European Payments Initiative case also meets these criteria. We discuss it in who designs for payment networks, so this list focuses on teams our other pages have not covered.

Bridge Studio: bulk payments for finance teams

Bridge Studio is a small UX and branding studio working in fintech, medtech, energy, and automotive. Its team works remotely, and the British Chamber of Commerce in Spain lists it at a Madrid address. The Onafriq case concerns the bulk payment platform of a digital payments gateway. The page describes the old journey as slow, error-prone, and hard for both internal teams and end users to navigate.

The studio mapped the existing workflows, wrote personas for operations managers and finance teams, and split each bulk payment into setup, review, and confirmation, with errors caught at upload. It reports 12% less time per bulk payment, twice as many transactions processed per hour, and 22% fewer support tickets about bulk payments. The case lists UX, UI, and frontend development, and the about page names six people, so confirm who would build the screens on your side.

Denovers: a live platform rebuilt surface by surface

Denovers calls itself an AI-first product design studio for B2B SaaS. Its contact page says it was founded in 2020 and works from Lewes, Delaware, for US operations and from Dubai for Gulf partnerships. The PayEngine case covers multi-processor payment infrastructure that other software companies embed: merchant dashboards, the transaction stack, and settlement runs. The product had been live for years, and the page lists cramped tables, low-contrast statuses, and long onboarding forms.

The work started with a 7-day trial on the transactions view, the main dashboard, and the search filters, then grew into the whole platform, including merchants, onboarding, settlements, and billing, on a shared component system. Creating a transaction moved from a multi-page form into one dialog for merchant, method, amount, and processor. The page reports a visible lift in engagement but prints no figure. Denovers offers an embedded senior designer on a monthly retainer, with an optional frontend engineer. The case calls the trial both free and paid, so check the terms.

Goodface: onboarding and approvals for a payments platform

Goodface lists offices in Bromley in the UK, New York, and Tallinn, and runs a fintech practice that covers payment platforms, merchant portals, and gateways. Its Emerald24 case concerns a UK multi-currency payments platform and e-money institution. According to the page, onboarding put identity checks, document upload, and validation into one long process, dashboards mixed daily and occasional actions, and web and mobile used different patterns for the same tasks.

Goodface split onboarding into stages that users can return to without starting over, and reports that the time to reach the review stage fell from 40 to 60 minutes down to 20 to 30. Clients who log in to approve many payments can now sign them in one batch. A task started on the web can be finished on mobile, with the existing password and SMS login kept in place. The project also covered the website and visual identity. Goodface’s other payments cases, for Corefy, Orbital, and GumballPay, are mainly websites and branding, so ask what other product work it can show.

Neuron: embedded design for payment and compliance software

Neuron is a San Francisco UX/UI agency for enterprise and B2B products. Its Givelify case covers a platform that more than 70,000 nonprofits and places of worship use to collect donations. Givelify first hired Neuron in 2019. Neuron then worked as an embedded team on its mobile and web apps, joined standups and roadmap planning, and built a shared design system with the in-house designers. One project redesigned the organization sign-up, which involves know-your-customer checks, moving it from a claim-your-profile model to a step-by-step flow.

The LegitScript case is adjacent rather than core: a merchant monitoring portal that payment providers use to check merchant risk and compliance. Over a two-month redesign, Neuron restructured the navigation, added a split view so analysts can open merchant details without leaving the list, and added risk notifications. Neither page prints an outcome metric. Givelify handles donations rather than merchant acquiring, so ask how the work would carry over to your merchants.

Phenomenon Studio: cross-border transfers people can follow

Phenomenon Studio is a product design and development agency founded in 2019, with more than 70 people in six countries and legal entities in Tallinn, Lugano, and Dover, Delaware. Its KlickEx case covers money transfers and mobile top-ups for Pacific Island communities, many of them migrant workers. The page names three problems: complicated procedures, verification that was hard to complete across several jurisdictions, and exchange rates that left people unsure what the recipient would get.

The team ran a UX audit, broke transfers into short steps, and added a calculator that shows the rate, the fees, and the final amount in both currencies before sending. The client wanted a detailed technical transaction history; the agency proposed a timeline of amount, recipient, and status that expands for details. The studio reports 35.3% higher conversion in the “Add Money” flow and 30.7% in “Money Transfer.” It also built the product, so decide early whether you want design only.

StanVision: a new way to pay, designed from zero

StanVision is a senior team in Sofia that designs product UX, marketing websites, and brands for B2B SaaS, fintech, and AI companies, and builds sites in Webflow. Its SelfiPay case covers Bulgaria’s first facial-recognition payment, where a shopper pays with their face at the terminal. The page says nothing existed yet, and that the hard part was trust: asking shoppers and merchants to accept an unfamiliar way to pay.

StanVision designed the payment terminal interface and the mobile app alongside the brand and website, in three months. The page says the terminal explains what is happening and reassures people in real time. It reports 59% better first-time understanding in user testing and 42% more merchant inquiries after launch. StanVision also names emerchantpay as a 7-year client across a mobile wallet and a dashboard, but it describes itself first as a Webflow agency, so ask to see more product screens than websites.

How to choose

Pick the flow that is failing first, then read the cases that match it.

• If merchants or your own operations team live in transaction tables and settlement runs, compare Denovers’ PayEngine work with Bridge Studio’s bulk payments case.
• If applicants drop out during verification, look at Goodface’s Emerald24 onboarding, Neuron’s Givelify sign-up, and Phenomenon Studio’s KlickEx verification.
• If customers send money across borders and doubt the final amount, Phenomenon Studio’s KlickEx case is the closest match.
• If you are launching a new way to pay and need the brand, the product, and the site at the same time, StanVision’s SelfiPay case shows that shape of project.

Then ask every agency on your shortlist the same four questions:

1. Show the pending, failed, and refunded states from a payments case, not only the success screen. Our guide to payment states lists what each one should tell the customer and the operator.
2. Walk us through a payout or settlement screen. How would a merchant explain a gap between sales and the money that arrived? The payout reconciliation example gives you a test case to send.
3. Who owned the compliance requirements in that project, and when did the client’s compliance team review the designs?
4. What did the client measure after release, and who measured it?

Send two or three of these agencies the same real flow, with its current screens and the cases it has to handle, and compare the first release each one proposes. If your product is closer to a bank or wallet than to payments infrastructure, our comparison of fintech design agencies covers that wider brief.
