‘Payment partners’ and ‘payment providers’ are often used interchangeably. But in our view, the difference isn’t just down to semantics: there’s a meaningful distinction between the two.

A provider offers a service, but a true partner becomes an integral part of your team and is motivated to see your business thrive and succeed.

As a SaaS, you might be feeling frustrated with your current payment provider for one (or perhaps all) of the following reasons:

• You’re not getting strategic advice: Your specialty is SaaS, not payments. You need a partner who can handle payment strategy, freeing up your energy to focus on improving your software.
• Support is too slow and inefficient: Large payment providers often use a ticket support system, and it can take between 2 and 5 days for someone to respond. Once you do get a response, you often have to re-explain your business each time you request help.
• Fees are too high: Platform fees, even if they seem modest at first, can add up: especially as an SMB. You might be looking for a solution that leaves more revenue on the table for you.
• Overwhelmed by features: You have access to a long list of features, but you often wonder if you’re paying for tools that you don’t need.

Wading through payment jargon and endless feature lists can be frustrating. To make it easier, this guide will break down what really matters when choosing a payment partner and the common mistakes to avoid.

Key qualities to look for in an ISV payment partner (and questions to ask)

When evaluating a payments partner, it’s important to go beyond surface-level sales pitches and assess how well they’ll support your platform’s real-world needs.

Here are the key qualities to look for, along with important questions to ask, to ensure they’re a strong long-term fit.

They’re eager to share their payments expertise with you

As a software provider, your focus should be on innovative software development, not on becoming an expert in payments. A strong payment partner helps you bridge this gap. They act as an operational and strategic advisor who actively helps you make decisions, optimize revenue, and avoid hidden pitfalls.

Good partners are more than reactive support desks. They proactively help you improve routing, reduce costs, and enhance the overall payment experience for your merchants and their customers. They keep up with your goals, check in regularly, and help you stay ahead of payment trends.

What to look for

• Revenue share: If a partner only succeeds when you do, they’re incentivized to help you grow. Look for shared success models.
• SaaS-specific experience: Review their customer base and see if they’ve helped similar SaaS businesses scale.

Questions to ask your prospective payment partner

• How often will we check in?
• Can you support us in strategic decisions?
• Do you have experience supporting SaaS companies like ours?

You’ll get a dedicated point of contact who knows your business inside out

Strong partnerships depend on trust and continuity. That’s only possible if you’re working with the same people each time. A dedicated team learns how your platform works, remembers your past issues, and gives relevant advice without you needing to re-explain things.

With a ticket-based model, you often lose time bringing new agents up to speed. Worse, it slows down urgent resolution when merchant issues crop up. A consistent contact you can reach out to directly reduces friction and gives you peace of mind.

What to look for

• A provider who guarantees you’ll work with the same point of contact or small team.
• Service levels that promise quick, multi-channel responses, not vague timelines.

What to ask your prospective payment partner

• Will we have a dedicated team that learns and knows our business?
• How quickly can we get support, and through which channels?
• Do you provide ongoing support beyond just answering tickets?

You can offer your merchants flexible pricing models

Pricing flexibility can have a direct impact on your revenue. Can you offer your merchants custom pricing or add your own markup to payments? If so, you create a recurring revenue stream. If not, you may be leaving money on the table.

A good payments partner lets you experiment with different pricing models, so you can respond to market trends, run promotions, or tailor offers to different merchant tiers. Flexibility means they’re invested in helping your business grow, not just locking you in.

Depending on your merchants and where they operate, that flexibility could also include offering credit card surcharging through your SaaS platform. A good partner should help you decide when it makes sense and how to implement it without creating unnecessary checkout friction.

What to look for

• Providers that support custom pricing or revenue-share models.
• Transparent documentation on pricing tiers, markups, and merchant-level flexibility.

What to ask your prospective payment partner

• Can we set our own merchant pricing?
• Is it possible to add our own markup?
• What pricing models do you support, and how easily can we change them?

They have proven experience supporting SaaS companies

Payments are complex. You want a partner who understands SaaS onboarding flows, supports integrated payments, and knows what your merchants expect from in-person and online payments.

A provider with experience scaling SaaS companies is more likely to offer APIs, workflows, and support that align with your needs and roadmap.

What to look for

• Features that address specific SaaS needs, such as multi-merchant onboarding or embedded UI options.

What to ask your prospective payment partner

• Can you share SaaS-specific examples of companies you’ve helped scale?
• How do your solutions fit into embedded finance or B2B SaaS platforms?

They have transparent and fair exit terms if it doesn’t work out

Not every partnership works out. You might grow faster than expected or need different functionality. That’s why it’s important to check how easy it is to leave if things don’t work out.

Some providers tie you into long-term contracts with steep penalties for early termination. That’s a red flag. A good partner doesn’t need to trap you — they’ll focus on keeping you by delivering value.

What to look for

• Non-exclusive contract terms with fair notice periods, no monthly minimums, and no early termination fees.
• No hidden termination fees or auto-renewal traps.

Questions to ask your prospective payment partner

• Are we locked into a long-term contract?
• What’s your cancellation policy?
• Can we leave if things don’t work out without heavy penalties?

Before choosing a partner, it helps to define what you actually need them to support. Our guide explains how to build a scalable SaaS payments strategy across onboarding, monetization, customer experience, and risk.

Three common mistakes that ISVs without payment partners make

Even the best SaaS companies have made plenty of errors when it comes to payments. Costly mistakes can be hard to avoid without the right guidance.

Here are some common mistakes we’ve seen, and how to avoid them:

1. Prioritizing profit margin too early

It might sound counterintuitive, but trying to optimize your profit margin too early (especially as an early-stage SaaS) can end up slowing down your business growth.

For example, you might be taking on a lot more operational burden than you need to be. If this happens, the cost of managing the added compliance, risk, and liability often outweighs any profit you’d be making from higher margins, especially if you have to make a new hire because of it.

(This is why we don’t recommend becoming a PayFac for most SaaS. Read more here: Why most SaaS platforms shouldn’t become a PayFac)

How to avoid this mistake

Many SaaS companies misprice their payment offerings because their provider doesn’t offer strategic guidance.

If your provider charges fixed platform fees, they get paid no matter what, so they have little incentive to help you optimize or course-correct.

In contrast, a partner with a revenue-share model is directly invested in your success. The more your payment volumes grow, the more value you both create, which aligns incentives from day one.

An aligned partner helps you avoid common mistakes from the outset. For example, if the adoption of your embedded payments is low, the focus should be on growing volume, rather than maximizing margin. That often comes down to making the integration simple, the customer experience smooth, and the incentives clear for your users.

2. Paying more for features you don’t need

Large payment providers often promote extensive feature sets. But for most SaaS platforms, many of these tools go unused and come at a steep cost. Real-time analytics dashboards, for example, might sound like a reasonable value-added service. However, access is often bundled with a flat-rate model, sometimes charging 0.30% to 0.60% above the interchange rate.

For a small to medium-sized SaaS, that margin could be better utilized elsewhere, such as improving the user experience.

How to avoid this mistake

Be realistic about what you actually need from your payment setup. Don’t pay for unused tools. A partner who understands SaaS will help you focus on what’s essential and advise when it’s time to layer in more advanced capabilities.

The right partner won’t push bundled features or upsells. Instead, they’ll show you how to reinvest those savings, for example, by offering more competitive rates to attract merchants or building a more sustainable revenue stream. Transparent pricing and aligned incentives create stronger partnerships and better long-term results.

3. Picking a provider based on a salesperson

When you first reach out to a payments provider, your point of contact is usually a salesperson. Their job is to sell the vision, and often, they do it well. You leave early conversations feeling confident, heard, and optimistic.

But sometimes, the problem comes later, when you’re handed off to a different team for implementation and support. The relationship shifts, and you may not get the same level of attention, service, or expertise you were promised at the start.

How to avoid this mistake

Don’t rely solely on the sales team. Ask to speak with product specialists, engineers, or integration leads early in the process. These are the people who’ll be supporting you day-to-day — and they’ll give you a far more accurate picture of how the partnership will actually work.

A good partner won’t just show off features. They’ll ensure you meet the people who will support you long-term and provide a transparent view of how they operate. If the team seems slow, vague, or disinterested now, that won’t improve after you sign. Prioritize providers who let you evaluate the full experience, not just the sales pitch.

A payment partner built for SaaS/ISVs: Fiska

Fiska was established by SaaS founders who understand what it takes to build, scale, and monetize software platforms. Unlike generalist providers, we act as an extension of your team: sharing insights, helping shape your payment strategy, and giving you the tools to create a revenue stream that fits your product.

Here’s what you can expect when you partner with Fiska:

A team of SaaS experts that understand your business

When you partner with Fiska, you’ll work with the same small team from day one. We act as an extension of your business: familiar with your platform, aligned with your goals, and able to offer meaningful advice without needing context every time you reach out. Our team is proactive: we step in when needed, and we’ll flag issues before they become problems.

Think of Fiska as your fractional head of payments. We’re not just here to provide infrastructure: we’re here to help you make better payment decisions. That means giving you the tools, insights, and guidance to build a payments strategy that supports your growth.

Regular check-ins ensure we stay aligned with your roadmap and give us a chance to share our SaaS expertise when it matters most.

You’re not locked in with Fiska. Our contracts last 3 years, and automatically renews annually. But because of our revenue-share model, we have no monthly minimums or early termination fees. Our partnership is also non-exclusive.

Retain complete control over your pricing and UX

With Fiska, you stay in control of your pricing. We’ll advise on strategy where helpful, but you decide what merchants pay: whether that’s a flat rate, interchange-plus, a blended model, or custom pricing for different customer groups. This flexibility enables you to align pricing with your go-to-market strategy, attract specific segments, and offer incentives such as volume-based discounts.

Our integrated payment solution is invisible, leaving your brand at the forefront. Think of Fiska as the plumbing behind the walls: invisible to your users, but powering everything securely in the background. You stay in control of the full customer journey, with no third-party redirects or external branding. To your merchants, payments simply feel like a native part of your product.

A true revenue-share model: we only make money when you do

We operate on a true revenue-share model. As a Fiska partner, you earn a percentage of the actual profit from payment processing, not just a markup on rates. We share our gross profit (the difference between what your merchants pay and the interchange), so you benefit directly from the value you’re creating.

This model keeps our incentives fully aligned. We only make money when you do, which means we’re motivated to help you grow, optimize your strategy, and maximize your payment margin over time.

Because of this alignment, we don’t charge monthly platform fees. Fixed-fee providers get paid no matter what. We don’t, so you can trust we’ll stay invested in your success beyond onboarding.

Experts who are just a Slack away, and Level 2 merchant support

Alongside strategic guidance, Fiska offers responsive, multichannel technical support through Slack, email, or phone. Our team is easy to reach and quick to respond. We only work with a select number of clients that are the right fit, so we always have availability to handle any support issues right away.

We provide Level 1 support for your team and optional Level 2 customer support for your merchants. This is a rare feature among payment providers. This means we can speak directly to your merchants and help them resolve their issues quickly and clearly, if you’re unable to resolve the problem yourself.

For instance, imagine you provide software for coffee shops. If your embedded payments go down one morning, and your merchant can’t accept card payments during morning rush hour, this could significantly impact their bottom line.

Clearly, your merchant will be frustrated, and direct that towards you. That kind of outage can damage your reputation, even if the issue isn’t your fault. With Fiska, any outage is considered critical by Fiska. We’re able to step in immediately and fix the problem directly if necessary, minimizing disruption and restoring trust.

Because our team is deeply familiar with your business, we can keep our support efficient, and step in at a moment’s notice.

Deliver a true omnichannel experience for your merchants

Fiska supports universal tokenization, allowing your merchants to store and reuse payment credentials across multiple channels and use cases. Tokens are secure, interoperable, and portable. This enables features like one-click checkout, card-on-file, and seamless repeat purchases: the kind of frictionless payment experiences used by Amazon, Uber, and other global platforms.

Combined with built-in omnichannel payment support, this gives your merchants the tools to accept payments consistently across online, in-person, and mobile channels.

All of this is delivered through a single, unified integration. With Fiska, even SMB-focused SaaS platforms can offer the polished, scalable payment infrastructure typically reserved for enterprise giants.

Pick a payments partner over a payments provider

As a SaaS, the sooner you start working with a payments partner, the better. Payment partners have your best interests at heart and can steer you in the right direction.

Fiska gives you a strategic partnership and a competitive advantage: we become an extension of your team that goes above and beyond to educate your team about payments. By working with Fiska, you’re not just getting a provider: you’re getting a partner who’s fully committed to your growth.

FAQs

1. What is an ISV payment partner, and why is it better than a standard payment provider?

An ISV payment partner (Independent Software Vendor partner) goes beyond basic payment processing. Unlike a standard payment provider, an ISV partner acts as an extension of your team, offering strategic guidance, flexible pricing, and embedded payment integration that supports your long-term growth.

2. How can ISVs earn additional revenue through embedded payments?

As an independent software vendor, you can generate additional revenue by embedding payments and applying your own markup. A true ISV partner supports custom merchant pricing models, enabling you to create recurring revenue streams without taking on the full compliance and risk burden of becoming a PayFac.

3. What should I look for in a white-label ISV payment solution?

A strong ISV partner should offer white-label functionality, transparent pricing, and control over your merchant experience. Look for support for omnichannel payment methods, no platform fees, and a revenue-share model that aligns incentives between your platform and the provider.

4. Why is dedicated support important for ISVs offering merchant services?

When offering merchant services through your SaaS, consistent support matters. An ideal ISV payment partner assigns a dedicated team who knows your business, responds quickly via Slack or phone, and can even provide Level 2 support directly to your merchants, reducing friction and protecting your brand.

5. Can an ISV switch payment processors without penalties?

That depends on your contract. Some payment processors lock ISVs into long-term agreements with hidden fees. A trustworthy ISV partner will offer transparent, fair exit terms with no steep penalties, so you’re never trapped if the relationship no longer serves your platform.
