Both routes run the same mechanic: backers commit money, and the project only goes ahead if it hits the goal. What changes is who owns the relationship and who takes a cut. Here is the math, without spin.
What Kickstarter costs
Kickstarter charges a 5% platform fee on everything you raise, plus payment processing of roughly 3 to 5% depending on your country. On a $20,000 raise that is about $1,600 to $2,000 gone before you make anything. You only pay if you fund, which is fair, but the bigger cost is invisible: the backers belong to Kickstarter's ecosystem. You get names and pledge amounts, not customer accounts, not a store relationship, and re-marketing to them later means starting over.
What running it on your own store costs
On your own Shopify store the campaign is just orders. You pay your normal Shopify payment processing (which you would pay on any sale anyway) and a flat app fee. Fundcap is $19 a month with no percentage of your raise, so the same $20,000 raise costs you $19 plus standard processing. Every backer is a real customer in your admin: their order, their email, their consent to hear from you again.
The honest trade: discovery versus ownership
Kickstarter's real product is its browse traffic. If you have no audience at all, a well-made Kickstarter page can be discovered by strangers, and that discovery can be worth far more than the fee. If you already have an audience (an email list, an Instagram following, a Discord, repeat customers), the platform adds little: you are bringing your own backers and paying 5% for a checkout you already own.
A simple rule
- No audience yet, product with broad appeal: Kickstarter earns its cut through discovery.
- Existing audience, repeat drops, or a niche you already reach: run it on your store and keep the raise, the emails, and the customer.
- Doing both is legitimate too: some brands launch flagship products on Kickstarter and run every restock and follow-up drop on their own store.
If you go the own-store route, the mechanic still needs to be real: a visible goal, a deadline, and an automatic refund if it misses. That is exactly what an all-or-nothing campaign does, and why it converts better than a plain preorder.
