Why it works
SmartSize is easy to recommend because the pain is obvious.
Every apparel, footwear, lingerie, kids, and pet store has sizing questions. SmartSize gives them two answers in one Shopify app: beautiful size charts and an AI size quiz. Your link simply connects that need to a tool merchants can install directly from the Shopify App Store.
How it works
Three steps from first mention to recurring commission.
Share with Shopify stores
Use your link in client work, content, newsletters, communities, app roundups, implementation docs, or store audits.
Earn every month
When a referred store installs and subscribes, you earn 20% of their payments for their first 12 months with SmartSize.

The details, in plain language
How much can I earn?
You earn 20% of every payment a merchant you referred makes to SmartSize for their first 12 months subscribed. The more active stores you refer, the more recurring commission you stack up.
How and when do I get paid?
Commissions are tracked and paid automatically through Mantle
. There’s no minimum payout threshold, so you don’t need to reach a balance before you can be paid.
Who can join?
Anyone who works with or reaches Shopify merchants — agencies, freelancers, consultants, content creators, newsletter writers and community builders. It’s free to join with no approval queue to wait on.
How long does the commission last?
You earn for the first year of each referred merchant’s subscription, starting from when they install and subscribe through your link.
How are my referrals tracked?
When you join, Mantle gives you a unique referral link. Anyone who installs SmartSize through that link is automatically attributed to you — no codes for merchants to remember.
Can I use the SmartSize logo and brand assets?
Yes — grab the logos, Shopify badges and brand colors from the brand kit
above. Please use the logo as provided: don’t recolor, distort or modify it.
