Start for FreeHow to Create a Professional Invoice
A professional invoice gets you paid faster. Include your business name, contact information, and any license or registration numbers at the top. This establishes credibility and makes it easy for customers to reach you.
Itemize every service performed and material used. Vague line items like “labor” or “parts” lead to questions and payment delays. Be specific about what was done, the quantities involved, and the cost of each item.
Set clear payment terms and stick to them. Net 30 is standard, but Net 15 or due-on-receipt works for smaller jobs. Include your accepted payment methods — the more options you offer, the faster you'll get paid. Online payments can cut collection time by 50%.
Include warranty information on every invoice. Even a simple “1-year labor warranty” reassures customers and reduces disputes. Keep copies of all invoices for your tax records.
Frequently Asked Questions
- What should an invoice include?
- A complete invoice includes your business info, customer details, invoice number, date, due date, itemized services with quantities and prices, subtotal, tax, total, payment terms, accepted payment methods, and any warranty or guarantee information.
- When should I send an invoice?
- Send invoices immediately upon job completion or the same business day. The sooner you invoice, the sooner you get paid. For multi-day or phased projects, send progress invoices at agreed milestones.
- How do I handle late-paying customers?
- Set clear payment terms upfront and include late fee language on your invoices (1-1.5% per month is standard). Send friendly reminders at 7 days, firm reminders at 14 days, and a final notice at 30 days. Consider offering a small discount (2-3%) for early payment.
