You're losing money to forgetful clients.

These are defensible estimates — not precise financial math. The point is to make the cost of late payments visible, not to produce an audit-ready report.

• Cash flow drag — We take the total value of your late invoices (annual invoices × average amount × delay fraction) and apply a 5% cost of capital. This is a conservative estimate of what that money costs you while it's sitting unpaid — either in borrowing costs or lost investment opportunity.
• Time cost — We multiply your hours per week chasing payments × 52 weeks × your hourly rate. This is money you're spending on admin instead of billable work.
• Uncomfortable moments — We estimate that ~30% of invoices require a follow-up, based on freelancer community data. These aren't a financial cost — but they're a real cost.

The formula: Total = cash flow drag + time cost
