Common invoicing mistakes

Small details that delay payment

  1. No due date

    'Payment on receipt' gets read as 'whenever'. A clear due date and terms set expectations.

  2. Missing reference details

    No PO number or wrong contact means the invoice sits in the wrong inbox.

  3. Nobody watching the aging

    Unpaid invoices get older quietly. A weekly look at 1-30 and 31-60 days catches them early.

FAQ

Questions, answered honestly

Do the templates calculate totals?

The Word templates are for clean layout; use the free calculator or the Excel register for totals. Many people keep both.

Do they include my country's tax rules?

No. Add tax only if you are registered, at your own rate, and check local invoice requirements.

Can I add my logo?

Yes. They're standard .docx files; insert your logo at the top.

How do I pay, and do you accept cards?

PayPal, or a debit/credit card through PayPal's checkout where PayPal offers guest checkout. You can also pay with Bitcoin (on-chain).

When do I receive my files?

PayPal: a private download link is emailed to your PayPal address, usually within about 15 minutes. Bitcoin: email your order code to eclipsekingdom.support@gmail.com; the link follows one blockchain confirmation. Links stay valid for 30 days.

What if a file doesn't work for me?

Email eclipsekingdom.support@gmail.com within 30 days and we'll fix it or refund you (PayPal refunds via PayPal; Bitcoin refunds in BTC for the USD value paid). See terms & refunds.
