The Smart Buy Button + cart solution driving 20%+ conversion for Eerdmans
Supadu developed a multi-format centralized eCommerce cart for Books International. This lets publishers offer robust D2C eCommerce without having to manage any eCommerce operations, as BI handles the entire transaction and fulfilment workflow.
Supadu's Smart Buy Buttons can be added to any website, blog, newsletter or marketing page, even without native eCommerce. Readers are taken directly to a Supadu-supported checkout, allowing publishers to sell books wherever their audience discovers them.


Why Eerdmans chose Supadu & Books International
Eerdmans considered building its own eCommerce site, but chose Supadu’s Smart Buy Buttons for their seamless integration with Books International’s fulfilment.
The solution lets Eerdmans focus on marketing and reader engagement while Supadu and BI manage all technical, transactional and logistical operations.
