PSP migration: what are we talking about?
PSP migration involves changing payment service providers to manage your online transactions. This can be driven by performance needs, cost considerations, or the desire for access to new payment methods.
A migration involves the transfer and configuration of:
- Financial flow,
- Merchant accounts,
- Customer data.
It requires ensuring that all ongoing transactions are properly managed and that historical data remains accessible for accounting and regulatory monitoring.
There are two types of migration:
- Complete migration: transactions and payment methods are transferred to the new PSP.
- Partial migration: some payment methods remain with the old PSP while others are managed by the new payment service provider.
This distinction allows companies to plan the transition according to their business and to limit the risks of disruption.
Why consider a PSP migration?
Several reasons may lead a company to consider a PSP migration.
Here are the elements to consider:
- Identify the limitations of your current PSP: a PSP may present certain performance problems such as a low acceptance rate, technical difficulties or a lack of flexibility.
- Hidden costs: high fees or disproportionate commissions can weigh on profitability. Furthermore, frequent payment refusals lead to lost revenue and directly impact turnover.
- Supporting the evolution of your business: migration can allow you to integrate new payment methods or launch on marketplaces, ensuring that the chosen solution supports the growth and complexity of financial flows.
Key steps in a PSP migration
To successfully migrate a PSP, it is crucial to follow a structured plan to secure payments and limit risks.
1. Assess your current situation
Start by analyzing the performance of your current PSP: acceptance rates, transaction costs, customer experience, and flow speed. Identify any pain points or limitations that are hindering your growth.
2. Define your needs
List the essential payment methods for your business, estimate transaction volumes, and identify your target markets. Consider regulatory and compliance requirements to ensure your future payment service provider (PSP) can meet them.
3. Choosing the right PSP
Select a payment provider approved by the ACPR that can support your growth, offering a scalable solution that is technically compatible with your existing systems (API, CMS, ERP). Also evaluate the quality of their support and guidance.
4. Involve the technical and business teams
Coordinating internal teams ensures that all aspects of the project, from the technical flow to business needs, are taken into account.
5. Anticipate potential errors
Identify risk scenarios, such as payment refusals or technical problems, and plan solutions to manage them quickly.
6. Prepare for the migration
Plan all project stages and organize financial flows to ensure continuity of payments. Properly manage customer data and merchant accounts so that transaction history remains accessible and secure.
7. Test before deployment
Perform functional tests on all payment methods and load tests to validate system performance. Also, verify the user experience across different journeys and devices to minimize the risk of abandonment.
8. Deploy gradually
Implement a phased migration to avoid disruptions. Track performance in real time and monitor key metrics such as acceptance rate and conversion rate. Develop a contingency plan to react quickly in case of problems.
This structured approach allows you to transform PSP migration into a performance lever while minimizing risks to your business and your customers.
9. Track key KPIs
Monitoring acceptance rate, conversion and overall performance allows for quick adjustments to the migration and ensures its success.
Can changing PSPs cause a service interruption?
Changing payment service providers (PSPs) doesn’t necessarily mean interrupting your payments, but a poorly planned migration can lead to temporary risks. A gradual and well-organized transition ensures uninterrupted cash flow.
In practice, it is common to implement a phase where the old and new payment service providers (PSPs) operate in parallel. This ensures that transactions remain possible during the data transfer and configuration of the new payment system. With careful monitoring and a range of tests, the impact on the service is virtually nil, thus guaranteeing seamless payment continuity.
The impact of a PSP migration on performance
A well-executed PSP migration can become a true strategic lever for your business. It allows you to increase acceptance rates, reduce transaction costs, improve conversion rates, and strengthen your ability to handle larger volumes as your business grows.
Beyond the immediate gains, a structured migration offers a long-term vision by optimizing the customer experience. Support from the payment provider and a phased approach are essential to ensure a successful transition and transform this change into a competitive advantage.
