Why your invoices get paid late (it's usually not the client)
Inconsistent timing and weak wording are often the real reasons invoices get paid late, not the client. To fix this, adopt a consistent schedule for sending reminders: 3 days late (friendly nudge), 10 days late (firm reminder), and 20 days late (final notice). Use specific wording, such as 'Hi [Name], invoice [INV-014] for $1,200 was due on May 30, I haven't seen it land yet. Could you check on it this week? Thanks!' to get replies. This approach can be implemented without any tools, but a free overdue-invoice email generator and a full system like Get Paid OS can also be used to automate the process.
