Klarna & PayPal BNPL Integration

I need our WordPress store to offer seamless Buy Now, Pay Later checkout with both Klarna and PayPal, first on a staging copy and then on the live site once everything is tested and approved.

Here’s where we stand:
• Stripe is already active and Klarna is enabled inside that account.
• I’m not certain whether the site is running WooCommerce, so I’ll rely on you to confirm. If it isn’t installed, please set up the latest stable WooCommerce version (or propose a better route if you know one).
• All BNPL options must be lightning-fast at checkout and display clearly alongside our existing Stripe methods.
• I’ll decide later whether BNPL should apply site-wide or only to specific product categories, so keep the implementation flexible.

Key milestones
1. Audit the current payment stack, verify WooCommerce status, and spin up a staging environment.
2. Integrate Klarna Pay Later and PayPal Pay in 4 / Pay Later on staging, ensuring they coexist with Stripe.
3. Walk me through testing; once I sign off, migrate the configuration to production without downtime.
4. Supply concise hand-over notes so future edits (e.g., limiting BNPL to certain categories) are straightforward.

Familiarity with WordPress, WooCommerce, Stripe APIs, Klarna, and PayPal SDKs is essential. Clean code, no performance drag, and a focus on user-friendly checkout are what will win this job.
