Install WooCommerce, then add PayPal using the official WooCommerce PayPal Payments plugin. In WordPress, go to Plugins > Add New, search “WooCommerce PayPal Payments,” install, and activate. Open WooCommerce > Settings > Payments, enable PayPal, and click Set up. Connect your PayPal Business account, approve permissions, and choose options like PayPal buttons, Pay Later messaging, and card payments (if available). Confirm your store currency, country, and SSL are correct. Run a sandbox or low-value live test order, verify webhooks created, and check refunds/captures update order status. Exclude cart and checkout from caching, and test on mobile before launching promotions thoroughly.

Stripe is usually better for WooCommerce if you want the smoothest online checkout, strong subscription support, and broad payment methods like Apple Pay and Google Pay. It has excellent developer tools, reliable webhooks, and often better global coverage. Square is better if you sell both online and in-person, because it unifies POS, inventory, and payments in one system. Square can simplify retail operations, but some WooCommerce features and extensions work more naturally with Stripe. Fees are similar, so decide based on your workflow: online-first stores usually pick Stripe, while physical shops or pop-up sellers often pick Square. Also check availability, payout speed, refunds, and dispute handling in your country.

To export WooCommerce orders to PDF, CSV, or other formats, you can use built-in tools or plugins. For CSV export, go to WooCommerce → Orders, click Export, and choose the date range and fields if available. For more control, install plugins like “WooCommerce Customer/Order/Coupon Export” or “Advanced Order Export.” These allow you to filter orders by status, date, or product and download them in CSV, XML, or Excel formats. To generate PDF invoices or order PDFs, use plugins such as “WooCommerce PDF Invoices & Packing Slips.” After setup, you can automatically attach PDFs to emails or download them directly from the Orders page.

In WordPress, go to WooCommerce → Settings → General and set your store address, currency, and selling locations. Then open WooCommerce → Settings → Tax and enable “Enable tax rates and calculations.” Choose whether prices are entered inclusive or exclusive of tax, how tax is shown in cart/checkout, and whether shipping is taxable. Create tax classes (Standard, Reduced, Zero) if needed. In each class, add rates: country/state, postcode, city, rate %, name, priority, and compound rules. Save changes. Optionally enable automated taxes using WooCommerce Tax (Jetpack) or a service like AvaTax. Place a test order to confirm totals for accuracy.
