How to Create an Invoice in 5 Simple Steps
Step 1: Add Your Business Information
Start by entering your business details at the top of the invoice. This information establishes your professional identity and tells clients who to pay.
Include These Business Details:
- • Business name - Your company or professional name
- • Your full name - Especially important for freelancers
- • Business address - Complete mailing address
- • Phone number - Main contact number
- • Email address - Professional email for correspondence
- • Tax ID or Business registration number - Required for tax purposes
- • Logo (optional) - Increases brand recognition
Pro Tip: Using our free invoice generator, you can add all this information in seconds, and it's automatically formatted professionally.
Step 2: Enter Client Information
Add your client's details so they know the invoice is specifically for them and where to send payment inquiries.
Required Client Information:
- • Client name or company name - Who you're billing
- • Contact person - Name of specific person (for companies)
- • Client address - Full mailing address
- • Email address - For electronic invoice delivery
- • Phone number - Alternative contact method
Step 3: Add Invoice Details and Numbers
Invoice details help both you and your client track payments and organize records.
Essential Invoice Information:
- • Invoice number - Unique identifier (e.g., INV-001, 2025-001)
- • Invoice date - Date you're issuing the invoice
- • Payment due date - When payment is expected
- • Payment terms - E.g., "Net 30" means payment due in 30 days
- • Purchase order number (if applicable) - Client's PO reference
Invoice Numbering Best Practices:
- • Use sequential numbers (001, 002, 003...)
- • Include year for clarity (2025-001, 2025-002...)
- • Add client code for multiple clients (CLIENT-001, CLIENT-002...)
- • Never skip numbers or reuse numbers
- • Keep a log of all invoice numbers
Step 4: List Products or Services (Line Items)
This is the core of your invoice - detailing exactly what you're charging for.
For Services:
- • Description - Clear explanation of service provided
- • Hours or quantity - Amount of time or units
- • Rate - Hourly rate or unit price
- • Amount - Total for that line (hours × rate)
Example Service Line Items:
- • "Website Design - Homepage redesign: 20 hours × $75/hour = $1,500"
- • "Content Writing - Blog articles (5 posts): 5 × $150 = $750"
- • "Consulting - Strategy session: 3 hours × $200/hour = $600"
With our free invoice generator, you can add unlimited line items and all totals calculate automatically - no math required!
Step 5: Calculate Totals, Taxes, and Payment Amount
The final section shows your client exactly how much they owe.
Invoice Total Calculation:
1. Subtotal
Add up all line items to get the subtotal (before taxes and discounts).
2. Discounts (if applicable)
Subtract any discounts: Early payment discount, volume discount, or promotional discount.
3. Taxes
Add applicable taxes: Sales tax, VAT, or GST depending on your location.
4. Total Amount Due
Final amount client must pay after all calculations.
