No payment method, no sales. WooCommerce gives you several options.
The usual choices
- Card payments through services such as Stripe or PayPal (free plugins).
- Bank transfer — simple, but the money arrives later.
- Cash on delivery — depending on your line of business.
Getting it running
Under Settings → Payments, enable the method and enter your account credentials for the service. Always place a test order before you open for business.
Important: offer card payments at the very least — that is what most customers expect.
