Sell-Side Technology Awards 2025: Best sell-side back-office platform—FIS
Product: FIS Post Trade Processing Platform

Overview
The FIS Post Trade Processing (PTP) Platform is a global, cloud-based, cross-asset software-as-a-service (SaaS) platform supporting post-trade processing across securities and derivatives. It is designed to integrate with front-office trading platforms and is connected to most major markets and industry utilities. It is typically used by:
- Broker-dealers with a regional/global footprint looking to consolidate their operations onto a single platform
- Local brokers requiring STP connectivity to their custodians and central securities depositories
- Market-makers and high-frequency trading firms with broad asset class requirements and large-scale volumes.
Over the recent years, we have enjoyed unprecedented growth levels. As we continue to diversify into new asset classes and trading strategies at ever increasing volumes, we need a flexible, scalable solution. FIS’ post-trade platform has demonstrated great capability. They provide a highly flexible cloud-based solution capable of scaling, when required, to provide us with the confidence we need to continue pressing our growth strategy

The solution
FIS’ PTP supports real-time, event-driven, multi-asset, multi-entity and multi-currency middle- and back-office processes, globally. Sell-side firms benefit from its scalable, modular, service-oriented cloud architecture (SOA), enabling them to select and scale to the right capabilities for their requirements. With the ability to support small to high volumes, firms can benefit from automated processes and drive high rates of straight-through processing with rapid exception resolution.
Secret sauce
FIS’ PTP platform is a post-trade platform designed to deliver real-time, multi-asset workflow processing from the cloud. It is also truly global, offering clients the ability to consolidate their global operations onto a single platform. Supporting T+0 settlement for clients in Asia, it is designed to support/enable shorter settlement cycles and is benchmarked to support the processing of over 100 million daily transactions on AWS.
Recent milestones
- Signed a significant number of new deals with sell-side firms across the US, Canada, the UK and Asia, following FIS’ acquisition of Torstone in early 2024
- Recurring annual revenue increased significantly year on year
- Went live with Bank of Ireland (Davy Capital Markets, Ireland’s largest broker) on FIS’ PTP for both middle- and back-office processing
- Enhanced integration and completed certification with the DTCC’s Central Trade Matching Platform
We’re truly excited by the significant growth we’ve achieved in 2024 following the FIS acquisition of Torstone, as well as our investment plans for 2025. We’re mindful of the unprecedented pressures financial services firms face, especially with the global shortening of settlement cycles, and we’re committed to helping our clients maximize their opportunities and improve their competitiveness with advanced technology
Mack Gill, head of securities processing, FIS Capital Markets
Future objectives
FIS will focus on:
- Establishing a larger US presence as it goes to market as part of the wider FIS team
- A wider rollout of its global middle-office solution to help with the T+1 transition
- Enhancing the combination of FIS products with the FIS PTP platform to deliver an integrated solution suite
Why they won
FIS follows up its success in the best sell-side back-office platform category of these awards 12 months ago by winning it again, thanks to its FIS Post Trade Processing Platform. Readers might remember FIS’ acquisition of Torstone and its Torstone Back-Office platform in early 2024, which enhanced FIS’ back-office offering, while also bringing with it a significant number of sell-side clients.
All back-office platforms worth their salt should provide users with three key benefits: improved operational efficiency and throughput, operational robustness and all-around increased transparency, and reduced operating costs through high levels of automation/straight-through processing leading to reduced back-office headcount. FIS’ Post Trade Processing Platform has those prerequisites covered, but the icing on the cake come in the form of the platform’s cloud-native architecture, allowing nimbleness and elastic scalability with minimal fuss to support all its clients’ specific requirements, while simultaneously minimizing time to market for new implementations and updates. Congratulations to FIS for another outstanding showing in this year’s SST Awards.
