Add Your Business Identity
Start by identifying who is issuing the invoice. Place your company logo prominently at the top, along with your official business or trading name, physical address, email address, and phone number. If you are registered for sales tax or VAT, always include your registration number.
Assign a Unique Invoice Number & Dates
Every invoice must have a sequential, unique number (such as INV-001). This prevents duplicate payments and gives your client’s finance team a reference for their ledger.
Always include two dates: the Issue Date (the day you send the document) and the Due Date (the deadline for payment, typically 14 or 30 days later).
Itemize Services & Products Clearly
Avoid vague single-line descriptions like “Consulting Services - $2,000”. Break down your work into recognizable milestones, deliverables, or billable hours. Include:
- Description of the task or product delivered
- Quantity or hours worked
- Unit price or hourly rate
- Line total
Specify Payment Methods & Instructions
Make paying you as effortless as possible. Clearly specify acceptable payment channels in the notes or terms section:
- Bank wire transfer: Bank name, account holder, routing code, and IBAN/BIC.
- Online payment links: A direct link to your Stripe, PayPal, or credit card checkout.
- Payment terms: Note whether early payment discounts or late payment fees apply.
- Missing due date: Simply writing “Due on receipt” can lead to delays. A concrete calendar date creates a tangible deadline.
- Unclear currency symbol: When working with international clients, always specify the currency code (e.g., USD vs CAD vs AUD).
- Forgetting purchase order numbers: Large corporate clients will often reject invoices that lack their internal PO number.
