Are you needlessly paying your staff to learn Excel?
Businesses normally use spreadsheets to fill gaps in their software and processes. You can avoid this completely by implementing bespoke software in your business. Bespoke sofware will allow your staff to concentrate on the value-adding tasks that they specialise in. Wouldn't you rather have your admin assistant chasing up unpaid invoices rather than searching through spreadsheets trying to find out who has paid and who has not?
