What We Offer in terms of Open Banking Payments & Pay-by-Bank Consulting

Payment Initiation & Pay-by-Bank Strategy

We help companies determine whether Open Banking payments fit their business model, customer base and payment volumes. We assess relevant use cases, customer adoption barriers, payment economics, regulatory considerations and the role of account-to-account payments within the wider checkout experience.

Open Banking Payment Provider Selection

Choosing a provider requires more than comparing API documentation. We evaluate bank coverage, supported payment journeys, market availability, commercial terms, transaction status reporting, settlement arrangements, refunds, reconciliation, technical requirements and operational support. We help clients define selection criteria, compare providers and structure the commercial relationship.

Checkout, API & Payment Flow Integration

We support the design and implementation of payment initiation journeys across e-commerce, SaaS platforms, marketplaces and digital products. Our work includes payment method presentation, customer redirection or embedded experiences where supported, authentication journeys, API requirements, transaction callbacks, payment status handling, reconciliation and exception management.

Payment Cost & Performance Optimization

We help clients assess the economics of Open Banking payments against cards and other alternative payment methods. Our analysis considers provider fees, operational costs, customer adoption, conversion, payment completion, refunds and the overall payment mix. We recommend changes based on the complete commercial and operational picture rather than headline transaction fees alone.

How We Work?

1

Assess the Existing Payment Setup

We review the business model, customer segments, payment volumes, current providers, checkout performance, operational processes and target markets. We identify where account-to-account payments could provide a meaningful alternative or complement to existing methods.

2

Evaluate Providers & Design the Journey

We define the required functionality, compare suitable PIS and Pay-by-Bank providers and design the target customer journey. We consider bank coverage, user authentication, payment status visibility, settlement dependencies, cost structure and technical complexity.

3

Coordinate Integration & Launch

We help prepare technical and business requirements, work with the selected provider, support checkout implementation and coordinate testing. Particular attention is given to unsuccessful or abandoned payments, duplicate requests, asynchronous status updates, reconciliation and the customer's experience when leaving or returning to the merchant's application.

4

Monitor Performance & Improve the Payment Mix

Following launch, we help measure actual customer adoption, completed payments, processing costs and operational effort. We identify opportunities to improve the payment journey, expand bank coverage, refine routing and integrate additional payment methods where commercially justified.

Pay-by-Bank is not automatically cheaper or better than cards

Account-to-account payments can provide an attractive alternative to card transactions, but the business case depends on much more than the advertised processing fee. Bank coverage, customer authentication, payment completion, reconciliation, refunds, operational support and customer preferences all affect the outcome. z3x helps companies evaluate the full cost and commercial impact before committing to implementation.

Build a payment experience that works beyond the successful transaction

A payment flow must also handle failed authorizations, customer abandonment, delayed status notifications, refunds and accounting reconciliation. These requirements are especially important for marketplaces, recurring commercial relationships and products with complex order management. We help design Open Banking payment implementations that fit the wider transaction lifecycle rather than treating successful payment initiation as the only outcome.

Frequently asked questions

It can be an alternative for suitable customers, markets and use cases. However, bank coverage, user preferences, authentication journeys and provider capabilities vary. We typically evaluate how Pay-by-Bank can complement or improve the current payment mix before recommending broader changes.

No. z3x provides consulting, provider selection and implementation support. Regulated payment initiation is performed by appropriately authorized providers under the applicable service model.

Some providers offer additional capabilities supporting these business processes, but their availability and legal or technical implementation vary. Standard payment initiation should not automatically be assumed to provide card-like recurring charging or integrated refund functionality.
