Every successful course starts with a great idea and hours of valuable research. 

But until now, if your course wasn’t fully finished, you couldn’t officially launch it, list it, or start selling.

That changes today.

We understand that waiting until every single video is shot and every workbook is perfected limits your momentum. That’s why we’re excited to introduce pre-order for Hosted Courses on Mainstack.

With this new feature, you can now accept payments for your course before it officially launches, validate demand, and start building excitement early.

Why Pre-Orders Matter for Mainstack Creators

With Pre-Orders on Mainstack, you can sell your course idea before it’s fully ready, giving you both validation and cash flow upfront.

Here’s what you can now do:

  • Validate demand early: List your course and confirm real interest from your audience before you finish creating it.
  • Earn while you build: Generate early sales to fund production, promotion, or upgrades.
  • Build anticipation: Turn your audience’s curiosity into a growing waitlist and early sign-ups.
  • Grow your community: Capture leads and nurture them before launch day.
  • Launch with confidence: Go live knowing you already have paying students and proof your course works.

Pre-Orders turn your next idea into income long before you hit “publish.”

How to Enable the Pre-Order Feature on Hosted Courses.

Setting up pre-orders for your course takes just a few minutes. Here’s how to start:

  1. Login to your Mainstack Dashboard and click Hosted Courses

  1. Select the course you want to open for pre-order (or create a new one).

For an already existing course, click on the course and scroll down to pricing and additional details.

  1. Turn on the Pre-Order toggle under the “Additional” details section.

  1. Add timezone, release date, and an optional pre-order message on button text (like “Launches January 15 – Secure your spot now!”).

Affiliate marketing has become one of the fastest and most cost-effective ways for digital product sellers to scale. Instead of burning cash on ads or struggling to grow reach on social media, merchants can tap into a network of motivated affiliates who promote their products for a commission.

The formula is simple:

  • Merchants get more sales and visibility.
  • Affiliates earn income by promoting products without creating their own.
  • Buyers discover trusted recommendations from people they follow.

With Mainstack’s Affiliate Marketplace, you don’t need complicated tools or long onboarding. Listing your product takes just a few minutes and it works seamlessly for hosted courses, products on your storefront, as well as bookings. Here’s how:

Step-by-Step Guide to Listing Your Product

Step 1: Log in to Your Mainstack Account

Start by logging into your Mainstack dashboard with your usual credentials.

Step 2: Navigate to Your Storefront

‍

From your dashboard, click on your Storefront, Hosted Courses or Bookings icon.

Step 3: Select the Product You Want to List

Choose an existing product from your storefront that you’d like to make available in the Affiliate Marketplace.

Step 4: Update Product Details

Under the product details page, scroll down to the Additional Details section.

Step 5: Enable Affiliate Listing

Toggle on the option that says “Add product to Affiliate Marketplace.”

Step 6: Set Your Commission

Decide how much commission you’re willing to give affiliates for every sale they generate.

Step 7: Upload Marketing Assets (Optional)

Help affiliates market your product better by providing:

  • Product images
  • Sales copy or sample captions
  • Any guidelines or FAQs affiliates need to position your product correctly

Think of this as your affiliate toolkit - the easier you make it for affiliates, the more likely they’ll promote your product.

Step 8: Save & Publish

Click Save, and that’s it!
Your product is now live on the Mainstack Affiliate Marketplace and instantly visible to affiliates who can start promoting it.

Every product you list on the Affiliate Marketplace is one step closer to:

  • More sales without spending a kobo on ads.
  • Wider reach by tapping into affiliate networks.
  • Faster growth with zero extra effort.

Affiliate marketing isn’t the future-it’s the now. And with Mainstack, you’re not just selling products, you’re unlocking distribution at scale.

List your product on the affiliate marketplace now!
