At a high level, the Partial.ly integration with BigCommerce works by having a Partial.ly checkout button on your website. The checkout button contains information about the customer's cart or product being purchased, and when the customer completes checkout through Partial.ly the order will be automatically created in BigCommerce. When the payment plan is fully paid, Partial.ly will update the BigCommerce order status, which you can control.
After you've connected your BigCommerce account there are a couple settings which can control how Partial.ly integrates with BigCommerce, which you should review. From the Partial.ly merchant portal, click the Settings link, then integrations. From there you can click the BigCommerce settings link.

You can also configure various options for how the Partial.ly checkout functions, by clicking on Settings then checkout anywhere in the Partial.ly merchant portal. If the products you are selling require shipping, be sure to check the Require customer shipping addresses checkbox, otherwise BigCommerce order creation may fail if your shop is set to require shipping addresses. To configure shipping zones and shipping rates, see our shipping settings article.
Adding the Partial.ly checkout button
Adding Partial.ly to your BigCommerce shop involves copying and pasting a snippet of code to which will embed the Partial.ly checkout button on your site. The checkout button is linked to an offer which determines the payment plan terms available to your customers. See our offers section for more details on how to create offers.
To add a Partial.ly checkout button to your shop, navigate to the Offers section in the Partial.ly merchant portal, then click the integration tool link next to the offer you would like to use.
This will then take you to the integration page where you can configure various options for the checkout button, and automatically generate a piece of code to copy and paste into your shop's template.
Select "With a Partial.ly button on my BigCommerce cart" from the first dropdown menu. If you want a minimum value for payment plans to be available, select the check box and enter a value. Next, you can select a button design. The HTML code in the box will be the code to copy and paste onto your BigCommerce site.
To edit your shopping cart template, go to your BigCommerce admin and click Storefront. On your active theme, click the Advanced dropdown menu, then click edit files. If you've never edited your theme before, you may need to create a backup first. In the theme editor, navigate to the cart template by clicking templates > pages > cart.html (the exact location of the cart template may vary depending on your theme). Click on the cart.html template, locate where in the template you want the Partial.ly button to appear, then copy paste the code from the integration tool.
For more details on configuring the checkout button, see our Partial.ly checkout button support article.
