What is a Payment Provider Migration?

Payment provider migration is simply moving your payment gateway, PSP, acquirer, or payment orchestrator to a different PSP. For SaaS companies, the migration generally involves switching integrations, routing logic, recurring billing data, and tokens with the checkout process running uninterrupted. Tokenization is a procedure where PANs are exchanged for tokens, leading to systems handling tokens and possibly altering PCI exposure levels.

Changing payment providers may affect various aspects of business and operations. Key characteristics encompass specific authorization rate levels, varying payment processing fee structures, modified fraud monitoring, geographic availability, and user interaction aspects influenced by transaction success rates.

In terms of SaaS businesses, this is expected to be associated with various outcomes:

•       An increase of 2-4% in authorization rates.
•       Chargeback rates exhibit a measurable quantity.
•       The per-transaction cost is recorded at a lower specific figure.
•       Fewer customer support tickets.
•       Sensitive data protection can involve tokens.

The payment migration process involves various components, and the understanding of associated risks relates to operational or procedural considerations.

•       The analysis explores the factors of interruptions, downtime, and transaction failures, and their significance for revenue and customer trust.
•       A range of token transfer functionalities is presented by different providers; some do not include import or export capabilities.
•       Data mapping, in the context of moving confidential customer and transaction records, can present differences.
•       Maintaining PCI DSS scope and compliance level throughout the migration process.
•       A temporary decrease in authorization rates was noted following the change.
•       Disruptions that elicit customer feedback impact the user experience.
•       Webhooks parity, retries, and refunds have to work properly across different systems.
•       Recurring billing continuity must be carefully planned not to interrupt the subscribers.

Identify in-depth all your payment system components, flows, fees, contracts, and methods of payment first. You need to check your token inventory, recurring billing dependencies, fraud settings, and report requirements to list all integration points and impacts. You also need to ensure that the transition is planned with your rollout and rollback options as well as success metrics. Finally, prepare your team for the switch by testing in a sandbox with your new provider and running “soft-launches” to reduce disruption when the final migration ​‍​‌‍​‍‌happens.

Well-executed payment provider migration involves a series of actions: audit, select, implement, migrate, and decommission in that exact order.

1.   Analyze your current infrastructure, performance levels, and your business requirements.
2.   Decide on the providers to go with.
3.   Address technical items. Ensure the technical side of the change to your system is covered.
4.   Move data and tokens. Transfer the content to your new system.
5.   Perform testing and parallel live transactions. Catch errors during extensive testing and run both systems to become familiar with the new one.
6.   The process involves a gradual shutdown of the old system, followed by its decommissioning. You can decommission the older system or not do that at all, but decommission it in parts.

Choosing providers based on factors that influence their performance and adaptability to future changes is essential. Criteria should include 

• authorization speed, 
• range of payments handled, 
• the areas covered, 
• token portability, 
• fraud tools, 
• detailed reporting, 
• guaranteed uptime/SLA, 
• developer tools, etc.

Keep the existing gateway running as a fallback, and set up real-time monitoring of your key metrics. Track these continuously to catch issues early:

• Authorization rates and latency.
• Observations related to error codes and webhook operational states.
• Refund volumes.
• Customer support inquiries.

Ensure that your current payment gateway remains fully active and operational during the integration and testing phase of the new one. Then redirect a relatively small volume of traffic to the new system by canary routing each transaction as testing until full switchover. The live systems strategy is often connected with reduced interruption, which can facilitate live migration without requiring scheduled downtime.
