The successful candidate will enjoy a collaborative environment where your expertise in system implementation will directly influence operational efficiency and strategic decision-making.

What You'll Do

As an Interim Systems Accountant, you will take ownership of critical projects that shape the future of financial management within the organisation. Your day-to-day activities will involve steering the transition from legacy systems to advanced platforms, ensuring every stage—from requirement gathering through data migration to user training—is executed flawlessly. You will work hand-in-hand with colleagues across departments to understand their needs, provide expert guidance on best practices, and champion process improvements that elevate operational effectiveness. By designing automated reporting frameworks and safeguarding data quality, you will empower leadership with actionable insights while ensuring compliance remains uncompromised. Your ability to communicate complex technical concepts clearly will be essential as you nurture user confidence in new systems. This role places you at the intersection of technology adoption and financial stewardship—making your contribution vital to both immediate project success and long-term organisational growth.

Lead the end-to-end upgrade and implementation of a new financial system, managing the transition from Sage 50 to ensure minimal disruption to business operations. Collaborate extensively with internal stakeholders to gather business requirements and tailor system functionalities to meet organisational objectives. Oversee the entire system migration process, including meticulous data transfer, comprehensive testing phases, and successful rollout across departments. Deliver engaging training sessions and ongoing support for key users, fostering confidence and competence in utilising new technologies. Evaluate existing financial processes and systems to pinpoint inefficiencies, recommending and developing enhancements that improve reporting accuracy and decision-making capabilities. Ensure all accounting processes adhere strictly to industry standards and regulatory requirements, maintaining compliance throughout system changes. Work proactively within the business to optimise current platforms such as Guestline, Epos Now, and S4, integrating them effectively with upgraded systems. Support the finance team by maintaining accurate and timely financial records that underpin strategic planning and performance evaluation. Design and implement automated reporting solutions using Power BI or similar tools to streamline information delivery for management teams. Monitor system controls vigilantly to guarantee data integrity across all platforms, swiftly addressing any discrepancies or risks identified.

What You Bring

To excel as an Interim Systems Accountant in this transformative environment, you will bring substantial hands-on experience guiding organisations through complex system upgrades or migrations—ideally involving Sage 50 or similar platforms. Your technical acumen will be matched by your ability to translate business needs into practical solutions that enhance efficiency without compromising compliance. You are adept at building rapport with colleagues from varied backgrounds, providing clear explanations during training sessions while remaining sensitive to differing learning styles. Your attention to detail ensures data integrity is never compromised even as you juggle competing deadlines. With strong interpersonal skills rooted in empathy and cooperation, you thrive when collaborating on shared objectives—always ready to offer support or share knowledge where it benefits the wider team. Your commitment extends beyond technical excellence; you are dedicated to nurturing trust among stakeholders by consistently delivering reliable results.

Demonstrated experience leading financial system implementations or upgrades within medium-to-large organisations, ideally involving Sage or comparable platforms. Advanced proficiency in Microsoft Excel with proven ability to leverage complex formulas for analysis and reporting purposes. Hands-on experience with Power Query or Power BI (or similar business intelligence tools) for designing automated reports that inform strategic decisions. Familiarity with data integration methods such as ODATA or ODBC is highly desirable for streamlining information flows between platforms. Exceptional analytical skills paired with a methodical approach to problem-solving in fast-evolving environments. Excellent communication abilities enabling you to engage effectively with stakeholders at all levels and deliver impactful training sessions. Comprehensive understanding of accounting principles alongside best practices in financial process management within regulated industries.
