WooCommerce is nice as an order-to-sats system (for digital goods) and yeah, BOLT-11, it's the only thing that makes sense from a "good design" perspective.

What I think that BIP-353 tries to solve is that you can have an authenticated address for on-chain transactions rather than an address that can be easily MITM'd (for example by browser extension malware) whereas with DNSSEC you can authenticate the input (as long as you don't get exploited in fetching the wrong expected key).

I use Woocommerce to set up the order flow. I just have a plugin that calls up an invoice when the customer is ready to pay. The plugin requires the user to pay a BOLT-11 invoice and click a button that says they've paid the order. I doublecheck to match the invoice on the order and the payment in my wallet, and then it's good to ship. Also, Woocommerce won't see the payment as complete until the customer pays the invoice and clicks the "I've paid" button.

(also I don't have very many customers, so I probably could do it just by matching timestamps/amounts on orders and payments -- Woocommerce is pretty easy on Wordpress, though.)
