Sell supercharged subscription products

Sell products with automated recurring billing

Modular Merchant's subscription product system was built from the ground up to be like no other.

It's easy, powerful and robust, giving you full control over the automated invoicing process. Specify the products, bill dates and scheduling options from within your store's Administration Area — no need to jump back and forth between your store and merchant account control panels.

  • Sell on any schedule — a certain day of the month, anniversary date, every X days, and so forth.
  • Sell free trial products that dovetail into paid products.
  • A turnkey recurring billing solution that's completely automated.
Turn every day into payday with automated, recurring billing that runs on its own!
Sell downloads simply and securely

Sell downloads simply and securely

Modular Merchant's digital delivery system allows you to sell any type of file from any location.

Creating digital products couldn't be easier. The shopping cart's built-in Product Editor allows you to assign files to the products you create — no matter where those files are hosted. Then, your customers can download those files when they purchase that product.

  • Host your downloads anywhere — either with us or on your own servers.
  • No limits on the file size of your downloads — great for video and hi-res artwork.
  • Protect your intellectual property: the source location of your downloads is never revealed.
  • Track your downloads, traffic and bandwidth with intelligent reports and statistics.

Sell individual downloads, or even create entire digital libraries that your customers can subscribe to!

Manage website memberships

Monetize memberships on your website

Product subscriptions also function as a robust way to manage website memberships.

Membership management is built-in to the store's subscription billing system. There's nothing additional to install or activate — it's available and ready to go. Create "members only" content in your store or on your website in minutes.

  • Add password protected member's-only content to your products — no programming required.
  • Create password protected member's-only pages on your own website too.
  • Your store can validate your customer's memberships, even for pages hosted elsewhere!
  • Create membership rules easily, based on the products a customer has purchased.

Add profitable membership features to your website with the shopping cart's turnkey options!
