No. The integration reacts after checkout is already complete, not during it — so there's no added load or delay at the point of purchase.
It's a fair thing to worry about, especially if you've had bad experiences with heavier plugins in the past. Checkout is the one place on your site where every extra millisecond costs you conversions, so it's worth understanding exactly when and where this integration actually runs.
When it actually runs
- 01 The customer completes checkout normally — nothing in this step is touched.
- 02 WooCommerce marks the order as placed/completed, as it always does.
- 03 Only then does WooCommerce's native webhook system send a lightweight notification.
- 04 Document generation happens on the invoicing platform's own servers, entirely outside your site.
The customer sees their order confirmation exactly as fast as they would without the integration installed.
Why it's lighter than plugin-based invoicing
Plugin-based invoicing tools run inside your WordPress install, competing for the same server resources as everything else on your site — and they're the first thing to slow down or break after a WordPress or theme update. A webhook-based integration doesn't install anything: WooCommerce simply sends a small outbound notification, and everything downstream of that happens elsewhere.

Does connecting myDATA slow down my WooCommerce checkout?
No. The integration uses webhooks that fire after an order is placed, not during checkout, so there's no added load or delay for the customer at the point of purchase.
Does it add extra load to my WordPress server?
No noticeable load. Since there's no plugin installed and document generation happens on the invoicing platform's own servers, WooCommerce only sends a lightweight webhook notification.
