Migrating market data spend management tools is a complex but strategic opportunity for financial firms to reduce costs, enhance compliance, and streamline operations. With rising data costs and increasing risks, successful migrations require deep expertise, clear workflow understanding, and vendor-agnostic support. This article outlines how CJC’s Commercial Management team—trusted by Tier 1 firms—leverages multi-tool experience to minimise risk, ensure continuity, and unlock significant savings during tool transitions.

Market data spend management tool migrations can be among the most complex and high-stakes projects financial firms undertake. Whether you’re consolidating platforms, switching vendors, or realigning your global market data strategy, the risk of spiralling costs, compliance breaches, and disruptions to business operations is real.

One of the most overlooked and critical components of a successful migration is multi-tool expertise. Without clearly understanding of what your firm is currently/will be using, clarity on paid-for data, and what you realistically need, migrations can go over budget, time and under-deliver. That’s why vendor-agnostic market data spend management tools and expertise aren’t just helpful, they’re essential. When it comes to complex market data challenges, CJC is a partner trusted by Tier 1 firms worldwide.

Why Manage Market Data Spend?

Market data costs have surged over the last decade – rising 8.1% last year alone –  compounded by renewal fee increases of 14-18% between 2022 and 2024. A recent report even described current cost levels as “unsustainable.” As data license expenses outpace budget growth, firms must manage spend with discipline and precision and the tools are becoming increasingly essential.

Spend management tools provide the visibility needed for smarter decisions – tracking inventory, usage, and cost while supporting compliance and strategic planning. But migrating away from a legacy platform correctly is complex and rarely a straightforward task. Each tool is different,  and a successful transition is beyond mere a “lift-and-shift.” It requires data validation, cleansing, and workflow alignment to ensure reporting and planning accuracy.

"In a digital world where market data costs are rising quickly, it can be very easy for firms to lose track of their spend. Having a robust inventory tool can make all the difference and open up a large pool of savings that you otherwise didn't know were there."

- Tom Dawe, Market Data Administrator at CJC.

Why Change How Spend Is Managed?

 

Firms migrate spend management tools for various reasons—vendor limitations, system consolidations, or broader strategic changes etc. Regardless of the trigger, each migration is an opportunity to address legacy inefficiencies and gaps, implement best practices, and potentially realise significant savings.

For example, a feasibility study conducted by CJC’s Commercial Management team for a global bank revealed that consolidating their market data platforms could save the firm £1.3M annually.

However, these projects are not without risk. Poorly executed migrations may lead to parallel system costs, compliance issues, data inaccuracies, and missed savings. Without the right expertise, firms may ultimately spend more than they gain.

Want To Maximise Your Chance To Succeed?

To reduce risk and maximise value during tool migration, firms must prioritise three critical areas:

  1. Deep Market Data Expertise – Market data is both complex and expensive.
  2. Clear Workflow Understanding – Minimising business disruption requires full visibility of underlying workflows.
  3. Vendor-Agnostic, Multi-Tool Knowledge – Vendor-aligned teams often lack familiarity with your existing platforms, limiting their effectiveness.

This is where CJC’s Commercial Management (CM) team excels. With hands-on experience across all major spend management tools – like Excel-based systems. FinOffice, In-house solutions, INFOmatch, MDSL, and Optimize Spend – CJC offers more than just migration support. Our team transforms and backfills legacy systems into optimised, enriched platforms through a structured process (Illustration A) with demonstrated benefits and includes:

  • Data collation and standardisation.
  • Validation and cleansing.
  • Workflow mapping and replication.
  • API integration and report configuration.
  • Post-migration documentation and support.

Illustration A: CJC’s Inventory Maturity Model

"CJC has used cost saving initiatives to help multiple firms cut costs by a significant margin, we have then helped migrate their market data into an inventory platform and aided them in keeping track of their market data."

- Tom Dawe, Market Data Administrator at CJC.

This approach has delivered measurable results. Following a series of acquisitions, CJC supported a global financial services client in consolidating fragmented inventory data into a single, unified system. Within six months, the number of managed contracts rose from 56 to 411, including a surge in Bloomberg contracts from 1 to 98. This transformation enabled significantly enhanced oversight, improved data integrity, and greater operational efficiency (see Example 1 below).

Why is CJC's Support a Good Option?

However, migrations are only the beginning. CJC also delivers ongoing support to help clients improve processes, manage contracts, and streamline invoice management to enhance finance reporting and strategic planning.

Unlike vendor-aligned service providers, CJC is completely independent.  We do not develop or sell proprietary tools, allowing CM to offer unbiased advice and support across all platforms. The CM team is trained in multiple systems and brings extensive best practice experience from Tier 1 banks, brokers and vendors.

Advantages of working with CJC include:

  • A client-first, vendor-agnostic approach.
  • 100+ years of combined market data experience.
  • Multi-spend management tool expertise.
  • Deep understanding of market data structures and workflows.
  • Proven track record of success.
  • Industry backgrounds spanning database vendors, tier-one banks, and brokers.

Example 1: Streamlining Inventory Management Post-Acquisition

Following a series of acquisitions, a global financial services client engaged CJC to consolidate disparate inventory data into a single, unified system. The client had inherited multiple inventory sources, including data from various tools, Excel spreadsheets, and records reconstructed from invoices and contracts.

CJC led the end-to-end migration process, selecting a single inventory management platform and transferring all relevant data into it. This involved:

  • Tool Consolidation: Migrating data from legacy systems into the chosen inventory tool.
  • Data Integration: Incorporating Excel-based inventories and manually reconstructed data from financial documents.
  • Data Validation: Ensuring only accurate, high-quality data was uploaded through rigorous validation processes.

As a result of this initiative, CJC successfully increased the number of managed contracts from 56 to 411 within a six months. Notably, Bloomberg contracts alone expanded from 1 to 98, enabling more granular oversight.
