What goes wrong without it
Many established businesses still run important processes on software installed on a single office computer, on a local server in a back room, or on spreadsheets passed around by email. These setups often worked for years. They become a problem when the business opens branches, staff begin working remotely, or the one person who understands the old system moves on.
The risks are real but often invisible until something goes wrong. A hard disk fails and the latest backup is weeks old. A spreadsheet is overwritten by someone working on an older copy. A former employee still has the file on a personal laptop. Staff at a second location cannot see current data, so they phone the head office for every answer.
Old desktop software may also be unsupported. It might run only on an outdated operating system, receive no vendor updates and offer no way to connect with modern tools such as online payments, WhatsApp or mobile apps. The business ends up held back by the very tool it depends on.
