FAQs
How do you calculate late payment interest on an unpaid invoice?
Multiply the invoice amount by the annual interest rate, then by days overdue divided by 365. Example: $1,000 × 8% × (30 ÷ 365) ≈ $6.58 interest.
What interest rate should I use for late invoices?
Use the rate in your contract or invoice terms. Many freelancers use 1–1.5% per month (about 12–18% annually). Some countries set a statutory rate for commercial late payments — check local rules.
How does this savings estimate work?
It divides your unpaid AR balance by current average days outstanding to estimate daily cash tied up, then multiplies by the days you expect to shorten with consistent follow-ups.
Does docstoc email clients for me?
No. docstoc drafts follow-up emails; you review and send from your own inbox. That keeps your client relationship in your control.
