Designing a High-Conversion Payments Experience for ISVs | Forteembedded payments
From Click to Cash: Payments Experiences ISVs Can Use to Improve Conversion
CSG Forte TeamAuthor
Key Takeaways
The payments experience deserves its own design focus : Even small breaks in the flow—extra steps, confusing errors, redirects—directly reduce conversion and increase churn.
High-converting payment experiences combine seamless UX with smart controls : The strongest ISV flows use embedded payments, bill payment patterns, and growth-and-retention tactics like progressive onboarding, context-aware friction, and clear, branded error states.
Payments should be managed like a measurable product journey : Guide every step, track drop-off by segment and device, and iterate with your embedded payments partner to improve authorization, activation, and upgrade rates over time.
For independent software vendors (ISVs), your payments experience is no longer “just” plumbing. It’s one of the most important product journeys you own—and a direct driver of trial-to-paid conversion, upgrade adoption, and long-term retention.
Your customers expect to onboard, accept, and reconcile payments without ever leaving your platform. At the same time, they’re comparing you to the best digital experiences they use every day. If your flows feel clunky, confusing, or risky, they abandon—and they remember.
The opportunity for ISVs is clear: design a payments experience that turns intent into revenue—while your embedded payments partner helps you manage the complexity of risk, compliance, and scale.
This article walks through how to do that, from core customer experience principles to mobile design and analytics.
In this post, you'll discover actionable strategies for building a seamless payments experience that boosts conversion and reduces customer churn.
Why payments deserves its own design focus
The payments experience is different from the rest of your product for three reasons:
It happens at peak intent : By the time someone lands on your checkout, upgrade, or “pay now” screen, they’ve already said “yes” in their mind. Any friction you introduce here has an outsized impact on revenue.
It sits at the intersection of money, trust, and compliance : Payment flows must satisfy end users, your merchants, card networks, banks, and regulators—all at once. Even if you use an embedded payments partner, how you collect data affects what’s possible for KYC/KYB, AML, Nacha, PCI, and ongoing monitoring.
It’s a shared journey across multiple models : The same user might pay an initial invoice, set up recurring billing, update a card, switch to ACH, or make an in-app one-time upgrade. Treating each of those flows as separate one-offs leads to inconsistent experiences and fragmented data.
Key elements of a high-converting payment flow
A high-converting payments experience does two things well:
Several design patterns show up consistently in ISVs that convert well.
1. Progressive profiling and tiered underwriting
Onboarding is where growth and risk collide. Ask for everything up front and users stall. Ask for too little and your risk team gets nervous.
Progressive profiling : Start with lightweight data (business name, email, basic use case) and request more only as the customer approaches go-live, higher volume, or riskier features (e.g., higher-ticket transactions, payouts).
Tiered underwriting : Auto-approve low-risk merchants; route higher-risk verticals and large volumes to enhanced review with clear expectations.
This approach reduces form fatigue, gets more customers to first payment quickly, and still gives your embedded payments or payment facilitation-as-a-service (PFaaS) partner what they need for KYC/KYB and risk decisions.
2. Native, branded payment surfaces with secure components
Redirection is the enemy of trust. When users are bounced to a third-party checkout with different branding, drop-off tends to rise.
Keep users inside your product’s UI using embedded or hosted components for card and bank data.
Offload sensitive fields to your payments partner’s secure, PCI-compliant elements, while you control layout, copy, and brand.
This is where embedded payments shine: you get a consistent, in-product feel with a partner handling encryption, tokenization, and compliance behind the scenes.
3. Clear, actionable error states
Payment failures will happen. How you surface them determines whether users recover—or give up.
Specific messages : Distinguish “card declined,” “insufficient funds,” “account under review,” and “suspected fraud” instead of vague “Something went wrong” errors.
Inline guidance : Show users exactly which field needs attention and what to do next.
No data loss : Preserve form inputs when an error occurs so people don’t have to start over.
This not only improves conversion; it also reduces inbound tickets and time-to-resolution for your support team.
Reducing friction at checkout and in-app upgrades
Many ISVs lose revenue in two high-value places:
The first-time checkout (initial subscription, license, or setup fee)
In-app upgrades (add-ons, more seats, higher usage tiers, new modules)
These flows are often owned by different teams, use different patterns, and may not even share analytics. The user, however, just experiences paying your company.
1. Make the path to pay obvious and fast
For first-time checkout, minimize clicks from “start trial” or “subscribe” to “payment confirmed.”
For in-app upgrades, trigger the payment step directly from the feature or limit the user just hit—no detours through generic account pages if you can avoid it.
Short, linear paths with clear progress indicators tend to outperform complex, multi-step wizards.
2. Offer the right mix of methods, not every method
Too many options can be as paralyzing as too few.
At minimum, support major cards and at least one lower-cost method like ACH where it fits your use case—especially for recurring bill payments and higher-ticket B2B invoices.
Prioritize the methods your segments actually use. For example, small businesses might lean more on cards, while enterprise customers prefer invoice plus ACH.
Tie this into your bill payments strategy so that whether someone is paying an invoice, auto-paying a subscription, or upgrading an account, they see familiar, trusted options.
3. Make upgrades feel reversible and safe
Users hesitate to upgrade when they’re unsure what will happen if something goes wrong.
Your upgrade flows should clearly answer:
Simple answers reduce last-minute abandonment and encourage experimentation with higher tiers.
Designing payment experiences for mobile users
Mobile is often the first place users hit your limits: logging in from the field, paying a bill on the go, or approving a last-minute upgrade.
Designing a great mobile payments experience ISVs can rely on means taking small screens—and sometimes spotty networks—seriously.
1. Optimize forms for thumbs, not mice
Use single-column layouts with large tap targets.
Trigger numeric or email keyboards automatically for relevant fields.
Support autofill for address, name, and card data where possible.
The less typing required on a phone, the better your chances of completion.
2. Embrace express and wallet options
Digital wallets like Apple Pay and Google Pay can be powerful for mobile: they compress multiple steps (card entry, billing address) into a single action that feels safe and familiar.
Offering wallets alongside cards and ACH where your risk and business model allow.
Prioritizing wallets for one-time or low-amount transactions, while steering recurring or higher-value payments toward methods that support your margin and cash-flow goals.
3. Design for low connectivity and interruption
Mobile payers get interrupted. Make sure:
Sessions can recover gracefully if a user temporarily loses connectivity.
Key states (e.g., “Payment submitted, processing…”) are clearly communicated to prevent duplicate attempts.
Users can quickly confirm status in their account or billing history without calling support.

Frequently asked questions
What is a payments experience for ISVs?
It’s the end-to-end journey your customers and their end users go through to sign up, pay, get paid, and manage billing inside your software—from onboarding and KYC/KYB to checkout, refunds, recurring billing, and reporting. For many ISVs, this includes embedded payments, bill payment flows, and growth-and-retention tools like account updater or recovery workflows.
Why does payment UX matter so much for conversion?
Because payments sit at the highest-intent moment in your funnel. Every extra field, redirect, or unclear error is a place users can abandon. ISVs that streamline these steps typically see higher trial-to-paid conversion, more successful upgrades, and better retention, without changing their pricing or acquisition strategy.
Do we need to become a full payment facilitator to improve our payments experience?
Not necessarily. Many ISVs start with an embedded payments partner using models like PFaaS or referral/aggregator arrangements. These approaches let you embed modern UX patterns while your partner handles most of the underlying acquiring, risk, and compliance. You can always move toward more ownership later as volume and capabilities grow.
How does this apply if our revenue is mostly bill payments, not classic e-commerce?
The same UX principles apply. Whether you’re powering rent collection, invoices, membership dues, or usage-based billing, you still need clear amounts, flexible options, mobile-friendly flows, and predictable error handling. A unified approach across bill payments and card-present/card-not-present commerce makes it easier to measure and improve overall payment performance.
