Best practices for faster payments

• Send a polite reminder before the due date to reduce late payments.

Common mistakes and how to avoid them

• Missing client details — always confirm billing address and email.
• Incorrect tax calculation — keep tax rates updated and use the tool’s tax features.
• Vague descriptions — include enough detail to prevent disputes.
• Forgetting to attach supporting documents — attach proof of delivery or timesheets when relevant.
• Not tracking invoice status — use dashboard reports to monitor outstanding invoices.

Handling disputes and late payments

• Contact the client promptly with the invoice and supporting materials.
• Offer a payment plan if cash flow is an issue for the client.
• Document all communications and agreed changes.
• For persistent non-payment, follow a staged collections approach: reminders → phone call → formal demand → professional collections/legal help.

---

Security and compliance

• Use secure HTTPS connections and strong passwords.
• Limit access with user roles if you have a team.
• Keep records for the legally required period in your jurisdiction.
• Ensure invoices include legally required elements: business details, tax IDs, invoice number, date, and itemized amounts.

Troubleshooting common issues

• Invoice not delivered: confirm client email, check spam, and resend or download PDF to send manually.
• Payment not recorded: reconcile bank/processor reports, ensure payment method is connected, and mark payments manually if needed.
• Currency/rounding errors: verify currency settings per client and apply consistent rounding rules.

Metrics to monitor

• Days Sales Outstanding (DSO)
• Average time to pay
• Percentage of overdue invoices
• Revenue by client/project
• Invoice conversion rate (sent → paid)
