Shopify crowdfunding apps charge in three different ways, and the pricing model matters more than the headline number. A 5% cut sounds tiny and a monthly subscription sounds like a commitment, but which one actually costs less depends almost entirely on how much you raise. Here is the plain math, including the case where a percentage app really is the cheaper choice.
The three pricing models you'll see
- Flat monthly fee. You pay a fixed subscription while the app is active, regardless of how much your campaign raises. Predictable, but you pay it whether the campaign succeeds or not.
- Percentage of raise. The app keeps a cut of everything you collect, often somewhere in the 1% to 5% range. Your bill scales with your success, and sometimes drops to zero if the campaign fails.
- Usage fees. A small charge per order or per transaction, sometimes layered on top of a reduced monthly fee. These behave like a percentage model in practice: more backers, bigger bill.
The math at a $10,000 raise
Picture a six-week campaign that raises $10,000. On a $29 flat fee you pay about $58 across two months. At 2% you pay $200, at 3% you pay $300, at 5% you pay $500. Per-order fees land in a similar range: 200 orders at $1 each is $200. None of these numbers is outrageous on its own, but they come straight out of the margin you counted on when you set your goal. If you have not done that margin math yet, start with how to price and set a crowdfunding goal.
The math at a $50,000 raise
Same campaign, better result. The flat fee is still about $58. At 3% you now pay $1,500, and at 5% you pay $2,500. Nothing about the app's work changed. It processed more orders, which costs the developer very little, but your bill grew five times over because your campaign did. This is the same dynamic that makes Kickstarter's 5% platform fee sting at scale, and we compare those numbers directly in Shopify crowdfunding vs Kickstarter fees.
When a percentage app is genuinely cheaper
Flat fees are not always the better deal, and it would be dishonest to pretend otherwise. If your campaign raises $500, a 3% fee is $15, less than one month of most flat subscriptions. And if your campaign fails on an app that only charges on success, you pay nothing at all, while a flat fee is money spent either way. So for a tiny first test, especially one where you expect a real chance of failure, success-only percentage pricing has the lower worst case. If that is where you are, a small validation raise is a sensible move, and validating demand before buying inventory covers how to keep that test cheap.
A simple break-even rule
Divide your total flat cost by the percentage rate to find the break-even raise. Two months at $29 is $58, and $58 divided by 3% is about $1,900. Below that raise the percentage app is cheaper. Above it the flat fee wins, and the gap widens fast. Two things to check before you decide either way: whether there are per-order fees hiding under a low headline rate, and whether the percentage still applies to orders you later refund. Fees on refunded orders deserve special attention with all-or-nothing campaigns, and processing fees on refunds explains how those work on Shopify.
Fundcap uses the flat model: $19 a month, no percentage of your raise, no per-order fees, with a 14-day free trial. Building a campaign is free and the plan only starts when you go live. That makes us the cheap option at a $10,000 or $50,000 raise and, honestly, not the cheapest at a $500 one. Run the break-even math above with your own numbers before you pick any app, ours included.
