Mistake 1: Not Setting Clear Payment Terms

If your invoice doesn't say when payment is due, don't be surprised when it takes 60+ days to get paid. Always include specific payment terms:

• Due on receipt — for small projects or new clients
• Net 15 — payment due within 15 days
• Net 30 — standard for ongoing clients

Never leave the due date blank. InvoiceKit requires a due date on every invoice for exactly this reason.

Mistake 2: Using Generic or Ugly Invoices

A Word document with "INVOICE" in Times New Roman doesn't inspire confidence. Your invoice is a business document — it should look professional.

What makes a professional invoice:

• Your logo and business name
• Clean, readable layout
• Proper formatting for numbers and currency
• PDF format (not a Word attachment)

InvoiceKit generates professional PDFs automatically with your branding.

Mistake 3: Not Tracking Partial Payments

A client sends $500 of a $2,000 invoice. You make a mental note. Three weeks later, you've forgotten whether they paid $500 or $700. Now it's awkward to ask.

Always record payments immediately. InvoiceKit tracks partial payments and shows the remaining balance on each invoice.

Mistake 4: Forgetting to Follow Up

Studies show that 29% of freelancer invoices are paid late. The number one reason? Nobody followed up.

Set up a system:

• Send the invoice immediately when work is delivered
• Follow up 3 days before the due date
• Follow up on the due date if not paid
• Follow up weekly after that

InvoiceKit's recurring invoice feature ensures invoices go out on time, every time.

Mistake 5: Not Invoicing in the Client's Currency

If your client is in Europe and you send an invoice in USD, you're adding friction. They have to figure out the conversion, and the uncertainty might delay payment.

Invoice in their currency. InvoiceKit supports 35+ currencies — switch per invoice with one click.
