The Weekender Carry-On
Show delivery estimates, anywhere you show a product.
Delivery estimates don’t need to wait for the product page or checkout. Call the API from any surface your brand controls and show an accurate arrival date next to every product.
Put an arrival date on every product tile, so shoppers can filter and choose on speed as well as price.
Show when each result arrives, right in the results list and in predictive search.
Add delivery dates to “you might also like” and “complete the set” carousels to lift add-on sales.
Confirm the arrival date for the whole basket and show how long is left to order for it.
Pull live delivery dates into launches, restocks and gifting emails, so the message ends with when it can arrive.
Use the same dates in native iOS and Android apps, so every channel shows the same promise.
Show accurate delivery options, before the checkout
Show next day, standard and parcel locker options right on the product page, each with its own date and price, so shoppers can see their delivery options before they hit checkout.
Every delivery option, dated and priced
Return next day, standard and parcel locker options for the basket, each with its own arrival date and price, and show them in your checkout. It works in Shopify, Magento and custom checkouts.
Fewer “where’s my order?” tickets, happier customers
Pull the promised delivery date, service and carrier into your order confirmation, dispatch emails, or a bespoke tracking page. Shoppers see the same date across all touchpoints, so there’s no reason to get in touch to ask where their order is.
Personalised to every shopper, in real time.
Convert reads who’s shopping, where they are and what’s in the basket, then applies your delivery rules and returns the options that fit. Your front end just shows them.
Convert is the Zenstores delivery promise app. The Convert API gives you direct access to the tech behind it, so you can show accurate delivery dates, prices and options on your product pages, at checkout and in post-purchase comms, in your own design.
Anywhere you show a product: category and search pages, recommendations, the basket and campaign emails, as well as the product page and post-purchase comms. Native apps can use the same dates.
The Shopify app gives you ready-made widgets with limited customisation. The API returns the same delivery logic as data, so you decide exactly how it looks and where it appears, on any platform.
Any storefront that can make an API call. That includes Magento and Adobe Commerce, open source platforms like Saleor, Shopify Hydrogen, headless and custom builds, and native mobile apps.
From your Zenstores account. Handling times, cut-offs, carrier services, rates and delivery rules are set up once in Zenstores and applied to every API response, so changing a rule updates every surface.
Location, basket value and contents, weight, product tags and customer details, alongside live carrier service days and cut-offs. This is how one shopper sees free standard delivery and another sees courier only.
Yes. Show next day, standard, parcel lockers and click & collect side by side, each with its own date and price, on the product page and in the basket.
Yes. The option the shopper chose is stored with the order, so confirmation emails, dispatch updates and your warehouse team all work from the same date.
