The Expert's Playbook for Payments System Implementation: Best Practices and Insights

21st August 2023

Having spent 26 years working with payments projects across the retail sector, I’ve seen first-hand how challenging it can be to implement payments systems. There are many factors that can impact the success of a payments project. In this blog post, I’ll share my expert playbook for implementing a payments system, including best practices and key insights.

Understand clearly what you are trying to achieve:

Do not start by designing the solution. Start by establishing what you need to achieve as a business, and what the customer experience should be. Do not restrict this just to payments: this is only part of the story. Consider the whole user journey.

Payment Processing

Define your project scope and requirements upfront:

Once you are clear on the desired customer experience, then you can define the project scope and requirements. Do not try and design the solution at this stage. There are many approaches for delivering payment solutions. Working with payments experts will help you understand the options available and the implications of each.  

Choose a development partner with practical experience:

Payments is a complex world. Look for a development team with practical experience in working with a broad range of payment solutions. Weigh up the benefits of developing bespoke solutions against adapting existing software solutions. Work with the development team to decide which technologies are most appropriate considering your organisations standards. Also, consider cloud-based options.

Take a phased approach to development:

Payments system implementation is a complicated process that requires careful planning and execution. Taking a phased approach to development will help to minimise risk. Establish how your team will work with your chosen development partner. Decide how you are going to review the outputs throughout the development project. Set your testing strategy and agree your acceptance criteria. Know how you are going to implement the solution. Consider the benefits of piloting before rollout.

Prioritise resilience, transactions speed, ease of use, security and compliance:

Payment systems are the heart of your business. If your system is down you cannot trade, revenues are lost, and customers walk away. The user experience must be intuitive and transaction speeds need to be fast. Payment systems are a high-value target for cyber criminals. A data breach will have a massive financial impact and damage your company’s reputation. Consider how to design your system to minimise the costs of complying with  PCI:DSS (payment card industry – data security standard), the standard used within the payment industry to protect cardholder data. Ensure these features are built into your solution’s design from the project outset.

Test rigorously:

Payments systems must be tested thoroughly to ensure that they work as intended and are free from bugs and other issues. Plan for comprehensive testing throughout the development process, including functional testing, performance testing, and security testing. Polar Moment’s customers welcome our advice on test environment set up and management using both virtual and physical servers. We recommend development, test, pre-production and live environments. We are expert in the leading payment test tools, including T3 from Iliad.

Plan for ongoing maintenance and support:

Once your payments system is live, it will need ongoing maintenance and support. Work with your development team to plan for ongoing maintenance and support, including software updates, bug fixes, and customer support.
