How can SaaS platforms accept online and in-person payments with one integration?

For SaaS platforms offering embedded payments, supporting both online and in-person transactions is becoming essential. Many merchants expect to accept payments wherever their customers are.

The challenge is how you do this without bolting together separate integrations that create data silos, reconciliation headaches, and ongoing engineering drag.

The answer is true omnichannel payments: one merchant account, one integration, and a single set of payment objects shared across every channel.

In this article, we’ll explain what that actually means in practice, how most platforms approach it today, and why SaaS-first providers like Fiska are becoming a popular choice.

Omnichannel vs multichannel: why “one integration” matters

Many payment providers claim to support both online and in-person payments. But supporting multiple channels is not the same as being omnichannel.

Multichannel platforms offer separate products for online checkout, POS, and mobile payments. Each works, but they often operate in silos, with different APIs, reporting models, and customer records.

Omnichannel, by contrast, means every payment flows through the same underlying system:

• One merchant account
• One API
• Shared objects for customers, payments, refunds, disputes, and reporting
• A single source of truth across all channels

From a SaaS perspective, omnichannel is what makes “one integration” real, not just a marketing claim.

Patrick Huynh, CEO at Fiska, describes the difference between multichannel and true omnichannel in simple terms: “Most providers give you multiple pipes. Omnichannel is one system.”

In practice, that means the same customer, the same payment tokens, the same refunds, and the same reporting logic across every channel. Not three integrations stitched together, but one data model that runs through your entire platform.”

The most common approach to unified online and in-person payments for SaaS

Historically, platforms have defaulted to large, horizontal providers:

• Stripe + Stripe Terminal: Online payments combined with card-present readers under the same Stripe account.
• Adyen: A single API supporting multiple payment methods and channels with unified reporting.
• Square: Strong in-person and SMB tooling, with APIs for online and in-app payments.

These platforms can work, but they were not designed specifically for SaaS. Most started in retail or e-commerce and expanded over time, which often leads to inconsistencies between channels.

This is where SaaS-specific providers like Fiska differ. Fiska was built from day one to support omnichannel embedded payments inside software platforms, not retrofitted later.

Why SaaS platforms choose Fiska for omnichannel payments

Most providers built payments for merchants. Fiska built payments specifically for SaaS.

That distinction shows up everywhere, from pricing to APIs to support.

Build omnichannel from day one

Fiska’s white-label architecture is genuinely unified. There are no bolted-on products or channel-specific gaps. Security updates, compliance changes, and new features apply universally across every payment flow. 

Universal tokenization across channels

Payment details are tokenized once and can be reused securely online, in-app, or in-person. This enables one-click payments everywhere and reduces checkout friction: a major driver of higher conversion rates.

Revenue-share model: no platform fees

Fiska only makes money when you do. There are no fixed platform fees,  just a transparent revenue share that turns payments into a predictable income stream for your SaaS.
