7 Questions to Help You Find the Right Embedded Payments Provider

Payments used to be the part of a software roadmap that got handed off to a third-party processor and forgotten. Today, that model is being rewritten. 

Bain & Company estimates that U.S. embedded finance transactions will grow from $2.6 trillion in 2021 to more than $7 trillion by 2026, and most of that growth is happening inside software platforms — not on the websites of legacy processors. 

For software-as-a-service (SaaS) teams, payments have moved from a back-end utility to a central piece of product strategy, and the partner you pick to power them will shape your roadmap and your business users’ day-to-day experience for years. 

The hard part is that the embedded payments space is loud. Every provider promises easy APIs, fast onboarding, and revenue share. The actual differences show up in the fine print, the dev experience, the merchant onboarding experience, the available workflow customization, and the thoughtfulness of the deployment and support plan. 

Here’s how to cut through the noise to find the right embedded payments provider for your software platform. 

What are embedded payments? 

Embedded payments are transactions that happen outside of traditional financial environments. Think rideshare apps, social media platforms, business management solutions, and other non-financial environments where payments happen. This technology allows software providers to integrate the full payment experience — signup, checkout, processing, payouts, and reporting — inside their platform, instead of sending users to a third-party site or requiring them to manage a separate account. 

That means customers can sign up, start accepting payments, and reconcile sales inside the software platform they already use to manage their day-to-day. 

There are a few different ways to approach embedded payments: 

Referral model: With a referral arrangement, you hand merchants off to a processor and earn a referral fee. It’s easy to launch, but it offers weak monetization and a fragmented experience. 

Integration model: With an integrated approach, you bolt a processor’s API into your user interface for a better experience and more control, but you still don’t own the merchant relationship.  

Payfac model: Payment facilitators (payfacs) are entities that sponsor merchants under a master account, manage risk and compliance, and move money on behalf of the card networks. Becoming one yourself is technically possible and gives you more control over your merchants and revenue. However, it also requires you to establish banking relationships, build risk and know-your-customer (KYC) operations, hire compliance team members, and shoulder the full weight of card network rules. Most SaaS platforms shouldn’t go down that road. 

Embedded model: With a true embedded model, you sit on top of infrastructure that lets you onboard, underwrite, and serve merchants under your brand, while a partner handles payments for you. You earn a share of the revenue, so your profits grow as your users process more payments. 

The right embedded payments partner removes the burden of becoming a payment company, while still giving you more control than you would have with a traditional referral or integration model. They handle the underwriting, disputes, reporting, and payout rails, so your engineering and product teams can stay focused on building software.  

Why your embedded payments provider can make (or break) your integration 

Studies show that vertical SaaS platforms that add embedded financial products can increase revenue per customer by 2 to 5 times without changing their core software pricing. PYMNTS Intelligence also reports that 90% of SMBs now consider embedded finance tools essential to their operations.  

The upside is real, but only if the partner powering your platform can keep up with you. 

The wrong partner shows up in ways that are slow to diagnose and expensive to fix: a merchant onboarding flow that takes seven days when your competitor takes seven minutes; a webhook that silently drops events on important sales holidays; a pricing structure that chips away at your share as volume grows. 

None of those problems show up in sales demos, but they make a big difference six months later when you realize your payment solution is draining your resources. 

That’s why vetting matters. 

Here are a few questions worth asking before you choose an embedded payment provider. 

7 Questions to ask before you sign 

1. How robust is the developer experience? 

Start with the docs. Public, version-controlled, and complete documentation is a leading indicator of how the rest of the partnership will go. But the best providers go further: they give your developer — or your AI agent — the tools to move fast without guessing. Look for a platform that supports fully agentic development and curated developer skills or playbooks that walk you through credential setup, payment session creation, and test payments. 

The critical nuance: agentic doesn’t mean unsupervised. The right provider pairs autonomous tooling with curated human-in-the-loop checkpoints at the right inflection points — scoping the integration before a line is written, certifying in sandbox before going live, and backing every step with a dedicated solution engineer who’s in it with you.  

Done right, a developer or AI agent should be able to complete the integration in no more than a couple of hours. If the tooling isn’t built for that pace, your launch timeline is already slipping. 

2. Can you fully customize your in-app workflow? 

The payments layer should feel like part of your product, not a bolt-on. The way to get there is webhook-driven workflow customization. That means every meaningful payment event — like a merchant being approved, an API key being created, a terminal being added, a transaction being settled — fires a real-time event that your application can act on instantly. 

Picture a home-services platform where a merchant is approved and goes live. The moment approval fires, your software automatically grants access, kicks off device setup, and sends a branded welcome prompt — all without a single manual step. That’s not just a webhook; that’s your product, powered by payment infrastructure running underneath it. 

Ask prospective partners to walk you through every event in their webhook catalog and show you how to map those events to actions inside your application. If they can’t demonstrate a real-time, customizable event model — credit, ACH, voids, refunds, terminal status, held funds, settlement — the integration will always feel like a third-party tool your merchants have to leave your app to manage. 

With the right partner, everything will look like you built it from scratch. Because in the ways that matter to your merchants, you did. 

3. How automated is your application — and does it bring all payment types into a single enrollment? 

Onboarding is the first real experience your merchants have with payments inside your platform, and it sets the tone for everything that follows. The question worth asking isn’t just how fast the process is — it’s how much of it happens automatically. One form. One enrollment. Credit, debit, ACH, and embedded finance are all covered from the same application, so your merchants aren’t bouncing between workflows to get live.  

Ask whether underwriting rules are embedded directly into the application. When they are, the form itself becomes intelligent. That means it will dynamically surface additional fields based on the merchant’s business type, risk profile, or transaction patterns. That dynamic approach can eliminate the back-and-forth that turns a 20-minute enrollment into a week-long underwriting thread.  

Also, look at how modern the bank account validation experience is. With a proper integration, like Plaid, merchants can link their bank account instantly through a live connection — no voided checks, no manual entry, and no email threads asking for routing numbers. That kind of validation service typically drives a 20 to 30% lift in onboarding conversion on its own, since merchants who might abandon a paper-heavy form can move through a digital bank integration in seconds. 

4. What payment options can you support? 

The checkout your merchants need today might not be the checkout they need in two years. 

A serious embedded payments partner should give merchants flexibility across in-person and online transactions, ACH and bank-account debits, recurring billing and subscriptions, payment links, invoicing, digital wallets, and tap to pay on supported devices. 

Nearly 55% of customers say they would reconsider shopping at a local business after one bad payment experience. For your business users, access to reliable, flexible payments can mean the difference between success and losing sales to big-box competitors. And if they’re not getting those solutions from you, they’re getting them from someone else. 

Offering a variety of payment options is especially important for SaaS platforms serving verticals with mixed transaction patterns. For instance, a wellness studio needs to accept in-person payments at the front desk and process recurring memberships, while a general contractor needs to send large invoices that require ACH and payment links.  

The right partner handles it all through a single integration, with a credible roadmap for what’s next. 

5. What does your monetization model look like? 

Embedded payments offer a unique opportunity to turn what used to be a cost center into a profit center. For most SaaS platforms, subscription pricing has a ceiling. There are only so many seats to sell and so many pricing tiers to climb before growth has to come from net-new users. Payments revenue works differently — it scales with the volume your merchants are already processing, so your profit grows as their businesses grow. 

That’s why embedded finance has become such an important piece of the SaaS playbook. When you build payments into your product, you tend to earn more from each customer over time. And merchants who run their daily operations through your software are much harder to lose. That means the same integration drives both revenue and retention. 

Ask your potential partner for the real economics before you sign: 

• What’s your cut of every transaction? 

• How does that grow as your merchants process more volume? 

• What happens when you cross into a new pricing tier? 

• Which costs — chargebacks, network fees, gateway fees — come out of your share before you ever see a dollar? 

A partner worth signing with will make sure you understand every detail before you do. One that isn’t will hand you a brochure. 

6. What does your support plan look like? 

Your platform’s brand is on the line every time a merchant calls support. That’s why the best embedded payments partners don’t just put you in a ticketing queue — they build a support model that’s genuinely designed around your program. Ask how the partner shares data with you, how quickly that data flows, and how it’s structured so your team can act on it without having to call someone to find out what happened. 

Ask whether support knowledge is centralized and instantly accessible — to every member of your support staff, not just a few people with logins to a separate portal. An up-to-date knowledge base means your team can resolve a merchant question in seconds instead of escalating it. 

Here are a few specific things worth pinning down: 

• Who is the named contact for your team? Will you have a dedicated partner manager, or be put in a shared queue? 

• How is real-time transaction and merchant data shared with your program, and how current is it? 

• Is there a knowledge base your entire support staff can access instantly — updated with partner-specific context, not just generic FAQs? 

• What does the go-to-market launch plan look like, and is there an ongoing program review cadence built in? 

7. How do you handle PCI compliance and tokenization? 

The less card data your software touches, the better. A strong embedded payments partner reduces your payment card industry (PCI) scope by handling sensitive data on your behalf.  

Network tokenization, where a card number is replaced with an equivalent token, lifts authorization rates and reduces decline-and-retry headaches when cards are reissued or expire. Because they’re issued by Visa and Mastercard, network tokens are often more secure than traditional encryption methods. The best solutions will let you use payment data for repeat purchases or recurring billing without having to host sensitive information on your servers.  

Non-compliance can be costly, so it’s important to ask a potential partner how they handle PCI compliance and tokenization. The more responsibility they can take off your plate, the better. 

Red flags worth walking away from 

Here are a few red flags to look for: 

• Documentation that requires a sales conversation to access 

• Webhook delivery guarantees that read more like marketing than engineering 

• Pricing the partner won’t put in writing 

• A sandbox you can’t use without an account manager 

• Long contracts with no exit ramp if performance lags 

Where to go from here 

Embedded payments are one of the most important product decisions a SaaS team can make. The wrong partner will cap your revenue, slow your roadmap, and show up in your support queue; the right one will handle the heavy lifting — processing, compliance, risk, payout rails, and dispute operations — so your team can stay focused on the software you set out to build.
