## Summary

The City of London is procuring consultancy and technical support for the safe migration of its online payment service from PayPal to Flywire, including managing the change and integrating the new payment provider with SITS. This is an information technology service requirement, covering the practical and technical work needed to maintain payment functionality during the transition. The buying organisation is The Mayor and Commonalty and Citizens of the City of London. The work is associated with the City of London, with the buyer’s address in the City of London. The requirement is focused on payment-platform change, systems integration and related consultancy rather than general technology support. It would suit firms that combine payment technology knowledge with experience of business-system integration and controlled migration projects.

The procurement has been completed and awarded following a below-threshold limited competition. The buyer requested prices and service details from at least three suppliers. The award was made to Stu3 Limited on 26 July 2026 for the single lot. The contract was signed on 26 July 2026 and runs from 27 July 2026 to 2 April 2027. Its gross value is £65,520. The contract is active and the award remains active. The stated basis was suppliers’ price and details of the service they would provide. The requirement was treated as a services procurement, with information technology services as its classification. This was a limited competition rather than an open procedure, and the procurement was below the applicable threshold.

This award shows that the City of London buys specialist support for changing online payment providers where the work must be integrated with SITS. A credible competitor for similar work would need to demonstrate practical experience of PayPal-to-Flywire or comparable payment-platform migrations, including configuration, data and transaction-flow considerations, testing, technical troubleshooting and transition support. It would also need strong systems-integration capability and an understanding of how changes to payment services affect operational users and customer journeys. Consultancy skills are important alongside technical delivery: the requirement combines change management with integration rather than calling for a standalone software product. Suppliers should be able to present a clear service approach and competitive pricing, supported by relevant examples of safely delivering payment or enterprise-system change for public-sector or similarly controlled organisations.
