To set up shipping classes in WooCommerce, follow these steps:

1. Go to WooCommerce Settings: In your WordPress dashboard, navigate to WooCommerce > Settings > Shipping.

2. Select a Shipping Zone: Choose a shipping zone where you want to apply the classes.

3. Create a Shipping Method: Click Add Shipping Method and select a method (e.g., Flat Rate).

4. Configure Shipping Classes: Under the shipping method, you’ll find an option for Shipping Classes. Click on Add Shipping Class to create a new class.

5. Assign Products: Go to Products > Edit Product, and under the Shipping section, select the appropriate shipping class.

This allows you to apply different shipping rates for different product groups.

Go to WooCommerce → Settings → General, confirm your store address and currency. Scroll to “Enable taxes” and tick it, then Save changes. A new Tax tab appears. Open WooCommerce → Settings → Tax and choose whether prices include tax, how to display tax in cart/checkout, and whether shipping is taxable. Next, add tax rates: pick Standard (or create additional tax classes), click “Insert row,” then enter country/state, postcode, city, rate %, tax name, and priority. Save. Finally, place a test order to verify the correct tax shows for each location. If you sell globally, create separate rows per region.

Paying customers in WooCommerce usually means issuing refunds, store credit, or payouts for programs like affiliates or multi-vendor commissions. For refunds, go to WooCommerce → Orders, open the order, click Refund, enter amount/quantity, and choose Refund via gateway (if supported) or Manual refund. For store credit, use a gift card/credit plugin to add a credit balance customers can spend later. If you’re paying customers as affiliates/vendors, use plugins (AffiliateWP, WooCommerce Product Vendors/Dokan/WC Vendors) that calculate earnings and pay via PayPal/Stripe payouts or manual bank transfers.

WooCommerce subscriptions work by charging customers on a recurring schedule, like weekly, monthly, or yearly. You create a subscription product, set the billing period, price, and optional trial or sign-up fee. When a customer buys it, an order is created and a subscription record is saved in WooCommerce. The payment gateway then processes automatic renewals on each billing date. WooCommerce updates the subscription status (active, on-hold, cancelled) and generates renewal orders. Customers can manage renewals and cancel from their account page, based on your settings.
