Hi @ScribeMarjie. Congratulations on starting your new business! I use both Square (SquareUp.com) and PayPal - they both have similar fees for accepting payments. It may be worth exploring passing that cost onto your customers/clients.
PayPal has 3 options - and they're all useful depending on what you need:
- Subscription: for clients who'll need monthly services (e.g. Here. scroll down, click a "Buy Now" button). I choose to use the individual "buy now" buttons for this, because it's the only way to create a URL (instead of just a button code) on PayPal. This allows your customers to pay via PayPal or Credit Card! I can also easily use my websites own button designs, instead of PayPal's buttons.
- Shopping Cart: for clients purchasing multiple writing services (e.g. Here. scroll to bottom of page, click "Add to Cart"). Once you create the button, it creates a code that allows you to post that button on your website and, as @Rustler mentioned, allows customers to return to the 'shop' to add more.
- Buy Now: @Rustler 's favourite (I get it) may still come in handy for something. I don't have my PayPal account open right now, but really take the time to think through your clients/customers' behaviour, before you decide which buttons will work in each situation.
Hope this helps!
