Why This Calculator Matters
Most business owners don't realize how much time they're actually spending on invoice follow-ups. Between checking invoice statuses, writing personalized emails, and tracking responses, those "quick" reminder emails add up fast.
This calculator helps you understand both the direct costs (admin time) and opportunity costs (your billable time) of manual invoice reminders. The results often surprise business owners—what feels like a minor inconvenience is actually costing hundreds or thousands of dollars per month.
With Zendu's automated invoice reminders, you can reclaim this time and focus on growing your business instead of chasing payments.
