Decision 1
Choose physical, digital, service, or subscription
The product type determines whether you need inventory, shipping, delivery access, booking, recurring billing, or none of those.
Commerce stack guide
Start with the transaction, then add only the software needed to complete it
An online-selling stack is not a shopping list. It is a chain: offer, page, checkout, payment, delivery or fulfillment, customer communication, and measurement.
Planning range$20-$500+ per month depending on product type, catalog size, and automationUse this for architecture planning, not as a vendor quote. Verify current pricing before purchase.

Decision framework
Make the choice in this order
Decision 2
Make checkout the center
The website, forms, email, and automation layers should support the transaction rather than compete with it.
Decision 3
Add lifecycle tools after the sale works
Email, CRM, automation, SEO, and design software are valuable when they improve acquisition, conversion, onboarding, or retention.

Do not buy this if
Software should remove a constraint.
- Do not buy inventory software for digital products.
- Do not add a CRM before you have a lead or customer workflow to manage.
- Do not pay for separate funnel, email, and automation tools if an all-in-one platform already covers the simple version.
- Do not optimize software before confirming people will buy the offer.
FAQ
Questions that change the decision
What is the minimum software I need to sell online?
At minimum you need a place to present the offer, a checkout or payment mechanism, and a way to deliver or fulfill what was purchased. Everything else depends on the business model.
Do I need a separate website and ecommerce platform?
No. Many platforms combine the website and commerce layers. Separate systems make sense when content, customization, or operational requirements justify them.
When should I add automation?
After a repeatable manual handoff exists, such as purchase to onboarding, order to fulfillment, or form submission to follow-up.
