❓ Frequently Asked Questions

What is the best way to handle late payments?

The best approach is automated invoice collection with clear payment terms, gentle reminders, and professional follow-up sequences. Tools like PingPaid can automate this entire process for you.

Late fees are typically calculated as a percentage of the overdue amount (usually 1-2% per month). You can use our free late fee calculator or let PingPaid handle calculations automatically based on your configured terms.

What should I include in a freelance contract?

A solid freelance contract should include: payment terms, late fee clauses, scope of work, revision limits, kill fees, and intellectual property rights. PingPaid offers free contract templates in our template library.
