Finance & Tax Technology That Works
From Day One
End-to-end implementation, automation, and support across the full finance and tax technology stack.
One Platform. Three Modules. Fully Integrated.
ONESOURCE Tax Provision, Corporate Tax, and Statutory Reporting are designed to work together - and Osprey Consulting has the expertise to implement them that way. Many of our engagements combine two or more modules, with data flowing between Tax Provision, Corporate Tax, and Statutory Reporting to create a single, joined-up compliance and reporting process.
We design and build the integrations between modules - not just the modules themselves. If you are considering more than one part of the ONESOURCE platform, implementing them together is typically more efficient and delivers a cleaner result than separate sequential projects.
ONESOURCE Tax Provision
End-to-end implementation of ONESOURCE Tax Provision for multinational group reporting.
ONESOURCE Tax Provision (OTP) is the market-leading platform for group tax provision and reporting for multinational organisations. Osprey Consulting has deep, hands-on expertise across the full OTP implementation lifecycle - from initial scoping and data analysis through to configuration, integration, testing, and go-live.
Mark Hart spent years as Director of Solution Consulting at Thomson Reuters, where he oversaw the consulting team for the ONESOURCE platform. That experience means we understand both the technical platform and the real-world tax requirements it needs to meet.

ONESOURCE Corporate Tax
Corporation tax compliance automation - tailored templates, streamlined review workflows, and clean data feeds delivering a faster, more reliable return process.
ONESOURCE Corporate Tax (OCT) automates the preparation, review, and approval of corporation tax returns. It replaces manual spreadsheet processes with structured, repeatable workflows - reducing the risk of errors and freeing your team to focus on higher-value advisory work.
We implement OCT from initial setup through to go-live, building return preparation templates tailored to your group structure and configuring data feeds directly from your ERP. We design the review and approval workflow around how your team actually operates - building in the controls and process improvements that reduce time in each compliance cycle.

ONESOURCE Statutory Reporting
Automated statutory financial statements at scale - global templates for large multinationals and Companies House digital filing readiness for UK groups ahead of the 2028 mandate.
ONESOURCE Statutory Reporting (OSR) replaces manual, Word and Excel-based statutory accounts production with a structured, template-driven process. For large multinational organisations, we configure the TR global account templates that produce consistent financial statements across dozens or hundreds of entities - with disclosures populated directly from trial balance data and local formatting applied automatically.
For UK groups, mandatory software-only filing at Companies House applies to annual accounts filed on or after 1 April 2028. Confirmed by the government on 9 June 2026 (after the original 2027 timetable was paused), it requires all accounts to be filed in iXBRL format using commercial software, with the existing web and paper filing routes for accounts closing. OSR - with its built-in iXBRL tagging and Companies House integration - is the natural platform for organisations that need to be ready. We implement OSR as a standalone solution or fully integrated with ONESOURCE Corporate Tax, covering everything from template design and data integration through to digital filing configuration and team enablement.

Alteryx Workflow Automation
Process automation for tax and finance teams - turning days of manual data work into minutes, with system integrations and API connections built in from the start.
Alteryx automates the data processes that currently consume your team's time. For tax and finance, that typically means pulling data from your ERP and other source systems via API or file-based connections, reconciling and mapping trial balances, preparing upload-ready data packs, and distributing outputs - all without manual intervention. Processes that previously took days or weeks are rebuilt as automated pipelines that run in minutes.
As a registered Alteryx Solution Provider Partner, we design workflows tailored to tax and finance use cases - not generic IT solutions. We build the integrations and API connections needed to connect your systems end to end, and we document everything so your team can understand, run, and maintain what we build. The goal is practical automation your people are confident using, not a black-box dependency.

Data Integrations
Connecting your ERP, source systems, and tax technology with reliable, auditable data flows.
Clean, timely data is the foundation of any tax technology implementation. We design and build the integrations that connect your systems ensuring the right data arrives in the right format at the right time.
We work across API-driven connections, file-based workflows, and RPA-assisted extraction depending on your system landscape. Every integration is documented, testable, and maintainable by your internal team.

Process Optimisation
A structured review of your current workflows, with practical improvements that stick.
Before implementing new technology, it is worth understanding exactly how your current processes work and where the real friction sits. We conduct structured process reviews of your tax and finance workflows - mapping what happens, where data moves, where time is lost, and where the risks lie.
Our review outputs are practical and actionable. We do not produce lengthy reports full of recommendations that sit on a shelf. Instead, we work with your team to prioritise improvements and begin implementation in the same engagement where possible.

Training & Support
Structured knowledge transfer and post-go-live support to keep your team confident.
Technology implementations only deliver lasting value when the people using the system are confident and capable. We provide structured training programmes tailored to your team - covering system navigation, data flows, configuration logic, and reporting outputs.
Post-go-live, we offer hyper-care support and ongoing advisory to handle questions, configuration changes, and system updates as they arise. Our support is direct - you reach us, not a helpdesk.
