Frequently Asked Questions

Should I include a late fee policy on my invoice?

Yes, it is standard practice to include a brief note regarding late fees (e.g., "A 5% late fee applies to balances unpaid after 30 days") to encourage timely payment.

How should I handle partial hours?

Convert minutes into decimals for easier calculation. For example, 30 minutes is 0.5 hours, and 15 minutes is 0.25 hours.

Is it necessary to list tax separately?

Yes, if you are required to collect sales or service tax, it should be clearly itemized as a separate line item so the client can distinguish between your service fees and government-mandated taxes.
