Prepared by: Graham Bell

• Electronic Point of Sale (EPoS) systems are increasingly common in all areas of business, most notably the retail sector

• Systems in use range from basic Electronic Cash Register to sophisticated high end packages

• One common feature, they use electronic data and some form of computing power

Electronic Point of SaleA Risky Business

• Electronic Point of Sales data forms part of the business records used to create VAT and Direct taxes returns

• There are a range of risks attached to the use of electronic data systems as data may be manipulated by the user

• HMRC requires assurance that traders’ systems and processes are operating correctly

• Systems normally create hard copy reports e.g. Sales Receipts requiring manual audit. Electronic data provides scope for a more comprehensive alternative E Audit

Data Acquisition and Analysis

• Generically most EPoS systems will use front end software sitting on a Data Base Management system such as SQL or Microsoft Access

• Reports can normally be generated but may be cumbersome and can lead to system down time

• An alternative is to acquire the underlying raw data

• IDEA supports Open Data Base Connectivity (ODBC) and data can normally be imported from suitable sources by this method
