There are several options when paying for your order.
Credit card online
This is the most commonly used option used by my customers and is processed directly through Shopify so extremely secure and safe.
Direct deposit
I've also set up the checkout to give direct deposit as an option.
When this is selected you'll receive the bank account details with the order confirmation email.
You can then transfer the payment from your account; once this clears into my account I'll mark your order as paid.
Credit card over the phone
Some customers prefer to place their order over the phone as it is a chance to clarify any small details you may have with customisations etc.
This is still very secure as I enter the details straight into Shopify without recording your card number.
This option can also be selected at checkout and you'll receive an email with the next steps.
Paypal, Klarna, Zip and Afterpay
At the moment I don't offer these payment options on my website due to the excessive merchant fees ( up to 5% of the order value).
