Submarket

SubMarket is a complete web application designed for selling digital products online.

It combines product management, checkout, promotions, upsells, cross-sells, webhooks, and built-in email marketing into a single platform.

Instead of assembling multiple tools to manage your digital sales, you get a ready-made code base that brings these functions together.

What You Get

A complete digital product marketplace

SubMarket provides the foundation for selling digital products from a single platform.

You can create and manage products, configure your offers, and build your own digital storefront.

It can be adapted for products such as:

• Software
• Source code
• Templates
• E-books
• Digital files
• Courses
• Resources
• Other downloadable products

Built-in upsells and cross-sells

Increase the value of each purchase with integrated offer management.

You can configure:

Upsells — Present an additional offer during the purchasing process.

Cross-sells — Recommend related products based on the product being purchased.

This allows you to build product relationships and create more complete offers directly within your marketplace.

Advanced product-level coupon system

SubMarket includes a flexible coupon system that allows you to control exactly how promotions are applied.

Coupons can be configured according to:

• Specific products
• Maximum number of uses
• Start date
• End date

This gives you more control over promotions instead of relying on a simple global discount system.

Integrated webhooks

Webhooks are built directly into the application, allowing you to connect SubMarket with external services and automation workflows.

This can be useful for:

• Automating actions after purchases
• Connecting external tools
• Sending customer data
• Triggering workflows
• Building custom integrations

Built-in email marketing

SubMarket also includes email marketing functionality.

You can manage email campaigns directly from the application and target customers according to the products they purchased.

For example, you can create a campaign specifically for customers who purchased:

Product A → Campaign A

Product B → Campaign B

This allows you to build more relevant follow-up campaigns based on purchase history.

Save and reuse email templates

Email templates can be saved inside the application and reused for future campaigns.

This makes it easier to maintain consistent communications and avoid recreating the same emails every time.

Templates can be prepared for:

• Product announcements
• Promotions
• Follow-ups
• Customer communications
• Cross-sell campaigns
• Product-specific campaigns

Make It Your Own

Customize the application to match your business identity.

You can change:

• App name
• Logo
• Branding
• Interface
• Store identity

For example, you could transform SubMarket into:

DigitalHub · SellStack · MarketFlow · DigitalStore · FileMarket · CreatorMarket · ProductHub

These are only examples. You choose the identity, domain, positioning, and direction of your marketplace.

What Can You Do With the Source Code?

The source code gives you the flexibility to:

• Deploy the marketplace on your own hosting.
• Customize the design and branding.
• Modify existing functionality.
• Add new product types.
• Extend the checkout experience.
• Create new promotional mechanics.
• Add integrations through webhooks.
• Extend the email marketing system.
• Build features specific to your business.
