Sezzle / Zip BNPL for Shopify

This is a build-to-order engagement, not an instant App Store download. After purchase we schedule a short kickoff to collect your Sezzle and Zip merchant credentials and store details, then build and install the integration on your store. Typical delivery is about 5 to 10 business days depending on the number of markets, providers and theme surfaces involved. We confirm the exact timeline in writing before work starts.

Every build includes a defined post-launch support window to fix anything that doesn't work as specified and to answer configuration questions. After that, you can keep us on for maintenance — Shopify theme updates, provider API changes from Sezzle or Zip, and new market rollouts can all require adjustments, and we offer ongoing support arrangements to cover them. You own the installed app and configuration either way.

Yes. Sezzle and Zip pay you upfront and carry the shopper repayment risk, so the merchant relationship and credentials live in your own provider accounts. We wire those credentials into the integration during the build — we do not resell or proxy the BNPL rails, and your settlement terms remain directly between you and each provider.

No. We deliver the on-site messaging as Shopify theme app extensions rather than hardcoded Liquid edits, so the widgets render through Shopify's app extension framework and survive theme updates. Per-market settings live in metafields, which means configuration changes don't require touching theme code.

We configure Sezzle and Zip for US, Australia and Canada based on where each provider is available and where you sell. Routing rules decide whether a shopper sees Sezzle, Zip, or both, using market and cart-value logic. If a provider isn't offered in one of your markets, we gate the messaging so shoppers only see options they can actually use.
