PS: I analysed over a year’s worth of reddit posts to figure out what’s working for founders as far as online payment gateways are concerned. You can check the full thing out here. However, here’s a summary of what other founders on Reddit recommend if your SaaS is still in its early stages.

Based on my extensive research across Reddit discussions, I've compiled the top recommendations for payment gateways that prioritize affordability and simplicity without sacrificing essential functionality. As a founder of an early-stage SaaS startup, you're juggling a million priorities with limited resources. Your payment gateway shouldn't be yet another complex system draining your time and money.

So… without further ado, here are:

The Top 5 Payment Gateways for Early-Stage SaaS Startups

Chargebee: The Startup-Friendly Subscription Manager

It’s great because:

But watch out for:

Best for: SaaS startups with subscription models who want to avoid building billing logic from scratch and can live with some feature limitations in exchange for zero cost.

BillaBear: The Self-Hosted Budget Option

It’s great because:

But watch out for:

Best for: More technical founding teams who are comfortable self-hosting and want maximum control while minimizing costs.

Lemon Squeezy: The Simple All-in-One

It’s great because:

But watch out for:

Best for: Non-technical founders who value simplicity and speed of setup over having the absolute lowest transaction costs.

Stripe: The Industry Standard Starter

It’s great because: Widely recognized and trusted in the industry Comprehensive documentation and extensive integration options Can start using it without having a registered company Reasonable starter fees before you scale

But watch out for: Recent price increases affecting profitability as you grow Doesn't handle tax remittance (just calculates it) Potential for account reviews and payment holds Becomes more expensive as you scale

Best for: Startups who anticipate complex integration needs or want the safety of using the industry standard solution.

Mollie: The European Simplicity Champion

Making the Smart Choice for Your Early-Stage Startup

When evaluating these payment gateways, consider these key factors that redditors repeatedly emphasize:

True Cost Calculation

Don't just look at the advertised transaction fees. Other Founders on reddit recommend calculating the true cost, including:

Growth Flexibility

Several founders shared cautionary tales about choosing platforms that were cheap at first but became prohibitively expensive or limiting as they grew. Consider:

Customer Experience Impact

Multiple Reddit posts emphasized that saving a percentage point on transaction fees isn't worth it if:

Developer Resources Required

Be honest about your technical resources. Other Founders on reddit consistently warned:

Most importantly, Always Have Plan B

One recurring theme across discussions between founders on reddit was the importance of having a backup payment method. As one experienced founder put it:

"We had all our payments running through a single gateway until they suddenly froze our account during a surge of new customers they deemed 'suspicious.' We lost nearly a week of revenue before getting it resolved. Now we always offer at least two payment methods." Surprisingly (at least for me), the analysis shows that adding PayPal as a secondary option despite its higher fees and issues can save you in an emergency. Many end-users still prefer it, and having it as a backup isn’t a bad idea.

Key Takeaways for Early-Stage SaaS Founders

Start with a free or low-cost option that meets your basic needs rather than paying for features you might use "someday".

Prioritize simplicity and good documentation over having every possible feature.

Consider tax handling requirements early, especially if you plan to sell internationally.

Factor in the hidden costs of development time and customer support burden.

Always have a backup payment method.
