Accounting Information Systems: ERP Finance Design, Transaction Cycles and System Controls – London, 6–17 Sep 2027

Programme overview

Introduction:

Accounting information systems often grow by patchwork: account codes added without logic, sub-ledgers that never agree with the ledger, interfaces that drop records and manual accruals that nobody can trace. Month-end slows, segment reports disagree and auditors cannot follow a transaction from source document to financial statement. This Core Concept course shows finance and audit staff how an accounting information system is designed, how each transaction cycle posts through ERP finance modules and how system controls and audit trails keep the data reliable. Participants build an AIS Blueprint with a System Control Matrix and Audit Test Plan.

Course Objectives:

• Design a chart of accounts coding block and a general ledger and sub-ledger structure that support statutory, segment and management reporting
• Map procure-to-pay, order-to-cash, payroll, fixed asset and inventory cycles to their source documents, posting rules and control accounts
• Configure period-end automation, including recurring journals, accruals, reversals and allocations, within an ERP finance module
• Specify input, processing, output and interface controls, together with access, change and operations controls, for each accounting cycle
• Test accounting data with audit trails and computer-assisted audit techniques to detect duplicate, unusual and unauthorised postings
• Plan the selection, data conversion, testing and upgrade of an accounting system with key users and finance stakeholders

Target Audience:

• Accountants who record, reconcile and close ledgers inside an ERP or accounting package
• Finance systems staff who maintain posting rules, master data, interfaces and user roles
• Internal auditors who rely on system-generated accounting data and audit trails
• ERP finance key users who test changes, train colleagues and raise configuration requests
• Finance process owners who take part in accounting system selection, rollout or upgrade projects

Why Attend This Course:

• Leave with an AIS Blueprint, System Control Matrix and Audit Test Plan built on a multi-sector case company
• Trace any transaction from source document through sub-ledger and interface to the financial statements
• Cut close delays and suspense balances by automating accruals, allocations and reconciliations inside the system
• Compare accounting system practice with finance and audit peers from trading, manufacturing, services and public entities

Conclusion:

Reliable accounting data depends on how the system is built, not only on the people who enter it. Week one covers AIS architecture, coding blocks, ledgers, transaction cycles, ERP finance modules, interfaces and period-end automation, tested on a distribution company case. Week two adds application controls, IT general controls, system segregation of duties, master data governance, system selection and upgrade, audit trails and computer-assisted audit. The final day produces an AIS Blueprint with a System Control Matrix and Audit Test Plan for a case company.
