How we help
At Oyster Data Services, we specialise in consulting and implementation services focused on financial planning (budgets and forecasts), reporting and business intelligence. We guide you along the journey of transforming your organisation’s financial, operational, and ESG data using leading technologies – empowering you to make confident, data-driven decisions.
Taking a user-centered approach to data analytics we focus on how people interact with data. By deploying a design-led strategy, we make insights clearer and more accessible. This ensures reporting tools are seamlessly adopted across teams, enabling faster and more effective decision-making.
Our collaborative approach ensures solutions are not only technically robust but also aligned with your team’s needs. From implementing new FP&A systems to optimising existing ones and providing ongoing support, we design user-friendly tools that unlock the full potential of your data.

What we do

What we do

DEVELOPMENT OF YOUR FP&A ROADMAP
At Oyster Data Services, we dive into complex reporting environments to actively listen to the unique challenges facing our clients. With extensive experience across commerce, finance, and operations, we specialise in meeting management, shareholder and debt covenant reporting requirements in multi-jurisdictional and multi-currency environments. We keep abreast of the latest FP&A developments and approaches and are perfectly positioned to develop this roadmap and guide you to bring your FP&A vision to life.
We achieve this by hosting workshops to gather information from stakeholders and end-users, ensuring we understand all perspectives before proposing solutions. After actively listening, we provide expert guidance, create RFP documentation, define ROI and goals, and develop detailed roadmaps to successful project implementation.

Financial planning & Analysis Transformation
In today’s fast-paced and competitive business environment, we help transform your organisation’s financial planning and analysis capabilities. With over twenty years FP&A experience and eight years’ experience building BI dashboards and data models, we empower clients with scenario-rich planning and forecasting tools. You shouldn’t have to wait days or weeks to see how changes in assumptions impact your forecast or budget bottom line, liquidity, or covenants. Imagine an hour-long discussion on key inputs that instantly generates your budget. This transformative approach to planning will allow your business to become increasingly agile.
We leverage Solver and PowerBI to meet your needs, from implementing cloud-based FP&A solutions from the ground up, to cleaning up and rewriting your Solver reports and budget inputs, and re-designing your PowerBI reports, all aimed at making them run faster and more robust with the necessary insight.

business intelligence
Having the right data is useless if you can’t easily understand or navigate it. Cluttered dashboards, inconsistent conventions, and a lack of information hierarchy prevents teams from adopting new products and systems that can boost your business’ bottom line. We ensure product adoption is not a hurdle by prioritising the design of our systems by integrating User Experience (UX) and User Interface (UI) design to maximise your return on investment.
We do more than make your dashboards visually appealing – we ensure they address the right problems, in the right way, tailored to your teams needs. We create BI dashboard mock-ups to facilitate clear communication among all stakeholders, ensuring alignment and sign-off before implementing your solutions.

solver implementation, maintenance and support
With the demands of a regular job, keeping up with changes and maintaining best practices in data, modelling and reporting can be overwhelming. Leverage our skills and experience to give you the capacity to focus on what matters most, without letting your FP&A process slip.
We implement, maintain and support your Solver environment, data and budget and reporting templates. Choose from our support contracts, ranging from technical support to the full management of your FP&A process. For new or existing implementations.
