Sezzle / Zip BNPL for Shopify widens the installment choices your shoppers see at checkout beyond the usual Klarna and Affirm. ECOSIRE builds, installs and configures a Shopify integration that surfaces Sezzle and Zip pay-in-4, interest-free messaging on product pages, the cart, and checkout — then routes shoppers to the BNPL provider you've enabled in each market.
Sezzle and Zip pay-in-4 interest-free options surfaced on product, cart and checkout pages
Multiple BNPL provider routing — show Sezzle, Zip, or both based on market and cart value rules
On-site messaging widgets delivered as Shopify theme app extensions (no destructive Liquid edits)
Per-market configuration (US / AU / Canada) stored in Shopify metafields
Custom Shopify app installed via OAuth using the Admin GraphQL API
Webhook registration for orders, checkout and app/uninstalled events to keep state in sync
This is not an instant App Store download. It is a build-to-order engagement: you purchase the one-time build, we connect to your store via a custom Shopify app using OAuth and the Admin GraphQL API, register the webhooks we need (orders, checkout, app/uninstalled), and deploy theme app extensions so the messaging widgets render in your live theme without hardcoded Liquid edits. Provider credentials (Sezzle merchant keys, Zip API credentials) stay in your accounts — we wire them in, we don't resell the rails.
Because Sezzle and Zip pay merchants upfront and assume the shopper-repayment risk, your cash flow is unchanged while average order value and conversion get a lift from a familiar pay-in-4 option. We configure US, Australia and Canada coverage based on the provider availability in your markets, store per-market settings in metafields, and ship an A/B-ready placement so you can test where the BNPL messaging performs best.
Every build is delivered installed on your store, verified end-to-end against a test order, and backed by a defined support window. You get the working integration, the configuration, and a short runbook — no fabricated screenshots, no stock testimonials, just the integration your store actually needs.
A store already running Klarna or Affirm that wants to add Sezzle and Zip so shoppers see the installment brand they already trust, lifting conversion without changing cash flow.
A brand selling into multiple BNPL-friendly markets that needs the right provider shown per country, with eligibility and currency handled correctly at checkout.
A conversion-focused operator who wants A/B-ready BNPL messaging placements and clean metafield-based configuration so experiments don't require theme surgery each time.

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.
