Flexilay and Lay-Buy are both real layby (lay-by) tools: the customer reserves an order, pays it off in instalments, and collects it once it's fully paid. Neither is buy now, pay later — there's no lending, no interest and no debt. That makes this a genuine like-for-like comparison rather than layby versus credit.
The differences are practical. Lay-Buy adds a "Lay-Buy" button to checkout through plugins and extensions (including Magento and WooCommerce) and is designed to run on PayPal. Flexilay runs on your own Stripe account, covers both ecommerce checkout and invoice payment plans, and ships with connectors for several platforms. This page lays out where each one fits.
