Which payment provider is most similar to Stripe but cheaper?
For SaaS companies, Stripe has long been the default choice for payments since it’s developer-friendly and easy to integrate. But Stripe charges a flat 2.9% + $0.30 per transaction, and that can become expensive fast.
This article will run you through how to find an alternative, including an analysis of Fiska, Helcim and Finix.
What “cheaper” actually means for a SaaS platform
Lower processing rates are the obvious thing to compare, but for SaaS platforms the full picture is more complicated.
There are three distinct ways a payment provider can be cheaper. The first is lower processing costs: paying less per transaction because you’re on interchange-plus rather than a blended rate.
The second is fewer fees on top: Stripe charges separately for features like Billing, Radar, and advanced Connect functionality that other providers include as standard or don’t charge for at all.
The third, and the one most SaaS platforms overlook, is revenue share: the difference between paying a provider to process payments and earning margin on every transaction your merchants process.
A platform processing $1M/month through Stripe at 2.9% is paying around $29,000 in processing fees. A platform on interchange-plus at a similar volume might pay closer to $18,000–$22,000 depending on their card mix. But a platform that also marks up interchange and keeps the spread could be earning $5,000–$10,000 a month on top of lower costs. That’s not a pricing comparison anymore: it’s a fundamentally different commercial model.
When you’re evaluating alternatives, be specific about which of the three you’re optimising for. They often point to different providers.

What are the closest alternatives to Stripe but cheaper?
Visa and Mastercard publish interchange rates that vary by card type, transaction size and channel. But regardless of the true processing cost, Stripe will still charge 2.9% + $0.30 (and keep the margin).
In contrast, providers like Fiska and Helcim that charge interchange-plus pricing give software platforms the same experience as Stripe but with full visibility into real processing costs. They also offer a lower, more predictable markup, which is especially important when you start processing higher volumes.
Here’s a quick cost comparison between the best low-cost Stripe alternatives:

How to evaluate the most affordable Stripe alternatives for your SaaS
To determine the most affordable for your business, you should:
- Compare all fees, not just transaction rates. Check for chargebacks and international surcharges, as well as refund costs.
- Review feature support. Ensure options like marketplace payouts and fraud prevention match your stack.
- Run a small-scale test. Process part of your volume with the new provider to see the real costs of processing payments firsthand.
- Get custom quotes from top alternatives. Top providers like Fiska, Stax, and Helcim all offer custom quotes, so you can receive quotes and directly compare which option is cheapest.
Why use Fiska as your Stripe alternative
Stripe’s convenience is valuable, but it comes at a premium cost.
For scaling SaaS platforms, Fiska’s interchange-plus model gives you more control over your payments. You can control what prices your merchants pay, customize your pricing to suit different merchants, and earn meaningful income from payments because of Fiska’s revenue share agreement.
“Stripe does one thing very well: it gives you a box full of powerful tools. But as soon as you fall outside that box, they’ll politely tell you it’s not for them. There’s no middle ground. At Fiska, we offer a true partnership, helping you build a successful payment strategy.” Patrick Huynh, CEO of Fiska.
FAQs: Which payment provider is most similar to Stripe but cheaper?
1. What is interchange-plus pricing?
Interchange-plus means you pay the actual card network fee (Visa/Mastercard) plus a small markup. It’s more transparent than Stripe’s flat rate because you see exactly where the money goes.
2. Why is Fiska cheaper than Stripe?
If you’re an early-stage startup processing small volumes, Stripe’s fixed rate setup may be convenient in the short-term. But as you scale, Fiska’s revenue share business model becomes far more cost-effective. Fiska gives you:
- Transparent interchange-plus pricing (no hidden margins)
- Revenue share on every transaction
- Customizable merchant pricing and onboarding
- Hands-on implementation support
3. How easy is it to switch from Stripe to Fiska?
Migrating from Stripe to Fiska is simpler than most SaaS teams expect. Fiska’s onboarding and integration process is fully guided, with a dedicated technical team that helps transfer your existing payment flows, customer tokens, and merchant data securely. You can keep your existing UI, and you can even run both systems in parallel during transition. Because Fiska’s API is Stripe-like in structure and developer-friendly, switching usually takes days rather than months, which makes it an easy move for growing platforms ready to reduce costs.
4. How much can SaaS companies save by switching from Stripe to Fiska?
SaaS platforms switching from Stripe to Fiska could see as much as 10–30% lower payment processing costs, depending on volume and transaction mix.
That’s because Fiska’s pricing isn’t padded with hidden margins or bundled fees. On top of that, Fiska offers revenue sharing, allowing software companies to earn on every transaction processed through their platform—something Stripe typically reserves for its largest partners. The more your payment volume grows, the more your platform benefits.
5. Does Fiska charge setup or monthly fees?
No. Fiska doesn’t charge setup, platform, or monthly maintenance fees. Unlike many processors that add recurring charges for access, support, or compliance tools, Fiska’s costs are purely transactional and transparent. You pay only for the payments you process — no surprises, no extra line items, and no hidden “program fees.”
