An enterprise resource planning (ERP) system is important for gathering key data from around the company. Large companies cannot run without a good ERP system. Small and midsize businesses (SMBs) might be able to get by with simple accounting packages and dozens of spreadsheets—obviously not as efficient as an ERP system and prone to errors.
Some SMBs might try to make the same systems continue to work as they grow just to avoid the pain of change. The bigger the SMB grows, the more difficult it is to maintain the slapdash system that worked when the business was smaller. Without a good ERP system in which to store data and provide a resource for monitoring operations, SMBs will only grow so far before disasters strike.
