A standard subscription selling option allows customers to pay automatically on a recurring schedule, with each payment aligned to an order or delivery.

Make sure you have:
Connected a payment gateway
Synced your products to GoSimple
Decided that a standard subscription is the correct model for this product
If not, complete those steps first.
From the GoSimple dashboard:
Selling options → Subscription plans → Create plan
This opens the Create Plan screen.
Enter a name for internal reference only.
This name is not visible to customers
Use a clear, descriptive name for your team
Examples:
Monthly Refill – Standard
Weekly Subscription – Core Product
This helps distinguish plans when managing subscriptions later.
Select Standard subscription.
A standard subscription:
Charges customers automatically at a recurring interval
Creates an order for each successful payment
Continues until paused or cancelled

These options control how the subscription appears on your product page.
Removes the one-time purchase option from the widget
Customers can only purchase via subscription
Use this if the product must always be subscribed to.
Combines multiple frequencies into a single dropdown
Keeps the product page cleaner when offering several intervals

Highlights the discounted subscription price
Displays the base price crossed out for comparison

Controls the display order of plans on the widget
Lower numbers appear higher

These settings affect how delivery fees are handled for subscription orders.
Charges a fixed delivery fee per order
Charges a delivery fee per product unit
Use these options only if your shipping logic requires it.
If unsure, leave both unchecked and rely on a third party integration, like BobGo.
Calculates subscription pricing and discounts using the compare-at price
Useful when compare-at pricing is already configured in Shopify

These settings control what customers can do in the customer portal.

Allows customers to skip their next scheduled payment
Allows customers to move the next charge date
Enabling these options reduces customer support requests and gives customers more control.
Once all options are configured:
Review your settings
Click Save
The subscription plan is now available to be assigned to products.
Once you click 'Save' on your selling option for the first time, the 'Assign Products' view will appear, allowing you to easily assign products to your subscription plan.

After creating a standard subscription selling option and assigning your products:
Review the product page widget
Test checkout in test mode
Each step is covered in its own guide.
