Frequently Asked Questions

Q1: How specific should my invoice descriptions be?
Very specific! Instead of "Design work - $2,500", write "Logo Design: 3 initial concepts, 2 revision rounds, final files in AI, EPS, PNG formats - $2,500". Specific descriptions prevent disputes, speed approval, and look more professional. Include deliverables, quantities, and timeframes whenever possible.
Q2: What's the most professional way to ask for payment?
Use confident, polite language: "Payment of $2,500 is due by February 10, 2026 (Net 30 terms)". Avoid apologetic ("Sorry to ask...") or desperate ("PLEASE PAY ASAP!!!") language. State facts clearly: amount, due date, and payment methods. Professional tone shows you expect payment as agreed.
Q3: Should I use formal or casual language on invoices?
Always lean toward professional/formal language on the invoice itself. Even if you have a friendly relationship with the client, your invoice is a legal document. Save casual language for the email cover note. Good rule: If it wouldn't work in a courtroom, don't put it on an invoice.
Q4: How do I word an invoice for partial payment?
Clearly state it's a partial payment: "Deposit Invoice: 50% Project Payment ($2,500 of $5,000 total)" or "Progress Payment #1 of 3: Milestone 1 Completion ($1,500)". Always show total project cost and how much has been paid/remains to avoid confusion.
Q5: What should I write in the email when sending an invoice?
Keep it professional and brief: Thank them, reference the work completed, state invoice number and amount, provide due date, explain payment methods, and offer to answer questions. See our email templates above for specific wording. Subject line should be clear: "Invoice #001 from [Your Business Name]".
Q6: How do I professionally word a late payment reminder?
Start friendly: "Friendly reminder that Invoice #001 for $2,500 is due on [date]". If overdue, be more direct: "Invoice #001 is now [X] days overdue. Please remit payment by [date]". Escalate gradually. Never use threats or aggressive language in early reminders. See our "Difficult Situations" section for detailed templates.
Q7: Should I include "Thank you" on my invoice?
Yes! A simple "Thank you for your business" at the bottom shows professionalism and appreciation. It's good for client relationships and costs nothing. Just keep it simple and sincere. Avoid overly casual phrases like "Thanks a million!" or "You're the best!"
Q8: What wording should I use for late fees?
Be clear and legal: "Late Fee: 5% monthly interest on overdue balances" or "Invoices unpaid after due date subject to $50 late fee or 5% monthly interest (whichever is greater)". Check local laws first—some places restrict late fee amounts. Always disclose late fees before work begins, not after payment is late.
Q9: How do I word an invoice for hourly vs project-based work?
Hourly: "Consulting Services - 40 hours @ $75/hour = $3,000" (include date range if helpful). Project-based: "Website Development - Complete E-commerce Platform (agreed fixed fee) = $5,000". Be clear which model you're using so client understands what they're paying for.
Q10: What if my client questions my invoice wording?
Respond professionally and quickly: "Thank you for reaching out. I'm happy to clarify any questions about Invoice #001. Could you please specify which items need clarification?" Then provide detailed explanation with supporting documentation if needed. Good invoice wording prevents most questions, but always be ready to explain your charges clearly and professionally.
