Manual data entry rarely shows up as a line item on a budget, which is exactly why it's so easy to underestimate. If someone spends even 30 minutes a day re-typing data between systems, that's over 120 hours a year — three full work weeks — spent on a task that produces zero new value and introduces the constant risk of a typo that causes a bigger problem downstream.
Connect the two systems directly — an order platform to a warehouse system, a form submission to a CRM, an invoice to your accounting software — so data moves automatically instead of through a person's hands. This is usually the single highest-return automation a business can build, precisely because it's boring, repetitive, and completely rule-based.
If you're not sure where to start automating, manual data entry between two systems you already use is almost always the highest-value, lowest-risk first project.
