What you can do
Set standards for your master data
- Formats for capitals, abbreviations, addresses, post codes, tax numbers, contact details, bank accounts, etc
- Check that all master data fits within your standards, if not, fix it
- Ensure there are the minimal number of vendors, customers, materials, etc., remove any duplicates
- If you can not delete files, block any that have not been used for 13 months
- Avoid “sundry” accounts - the volume of transactions will be higher than you expect and they are hard to check
- How a master file is created and who can create it
- If it is a significant control point then maintaining master data should be separated from transactional access (eg: setting up vendors should be separate from processing invoices and making payments).
- Trained personnel should maintain master data
- Database maintenance is a specialist skill set. Personnel should be methodical, detail focused and almost pedantic.
