IRIS Pay for SaaS and Software Companies: The Best Solution for B2B Payments and Subscriptions

IRIS Pay enables SaaS platforms and software companies to integrate direct bank account payments into their digital processes and automate a significant part of the work involved in B2B payments. Instead of requiring customers to create a bank transfer themselves and manually enter the IBAN, amount, and payment reference, the payment details can be pre-filled and the payment can be confirmed within the customer’s banking environment.

This is particularly relevant for SaaS businesses, where revenue depends on the timely collection of multiple recurring fees, licences, subscriptions, and contractual payments. In B2B models, a software company may serve hundreds of corporate customers with different plans, invoices, and payment terms.

That is why, in 2026, an efficient payment process is not measured solely by whether a customer can pay online. The cost of accepting payments, the time required to receive the funds, the level of automation, and the ability to link a specific transaction to the relevant customer, contract, or invoice are equally important.

Specific Features of Financial Models in Modern SaaS Platforms

The financial model of a SaaS platform is based on predictable and recurring revenue, making efficient payment collection a critical part of the business. Unlike a one-time software sale, Software as a Service involves an ongoing relationship between the provider and the customer.

Customers may pay a monthly or annual subscription, a licence fee based on the number of users, or a fee depending on their usage of the service. Corporate customers often have individual contracts and invoicing arrangements.

This means that the payment process is directly linked to revenue and cash flow management. The more a SaaS company grows, the more important it becomes to automate the processes between issuing an invoice, receiving the payment, and reconciling it.

The Risks of Failed Transactions and Expired Cards for Recurring Fees

Recurring card-based payments can be interrupted when a card expires or is replaced, when there are insufficient funds, or when a transaction is declined. For a SaaS business, this creates the risk that a customer who actually wants to continue using the service may become overdue because of an issue with the payment instrument.

There is another common scenario in B2B relationships. Payment may be made after an invoice is issued, requiring an employee of the customer to initiate the bank transfer manually. This adds another administrative step and creates the potential for delays.

A2A payments offer a different approach. The payment is initiated directly from the customer’s bank account to the merchant’s account, while the required payment parameters can be provided in advance. This allows a SaaS company to offer a convenient digital payment journey without relying on the entry of card details.

The High Costs of Processing Cross-Border Transfers

The cost of international B2B payments can become a significant factor for SaaS companies selling their services across multiple European markets. The exact cost always depends on the banks, payment service providers, currency, and contractual terms, so international payments cannot be considered equally expensive in every scenario.

For growing software companies, however, even a small difference in the cost of processing a single transaction can have a noticeable impact when multiplied across thousands of payments.

With an Open Banking A2A model, funds are transferred between the customer’s bank account and the merchant’s account. With IRIS Pay, payment acceptance costs are lower compared with the card-based model. For SaaS companies with growing international operations, this creates an opportunity to optimize payment infrastructure as the customer base expands.

Digitalizing Payments in the B2B Software Sector

The digitalization of B2B payments enables software companies to connect invoicing, payment, and payment status information in one continuous process. Instead of the finance team sending an invoice and waiting for the customer to initiate a bank transfer manually, the customer can be given a direct way to proceed with the payment.

This is a natural extension of the SaaS model itself. If registration, plan selection, user management, and invoicing already take place digitally, there is no reason for payment to remain a separate manual process.

IRIS Pay provides API integration capabilities for internal systems, allowing a specific payment to be linked to an order or another identifier and its status to be tracked by the company’s system.

Direct Account-to-Account Bank Transfers Without Expensive Intermediaries

Direct A2A payments allow funds to be transferred from the customer’s bank account directly to the merchant’s designated account. With IRIS Pay, the funds are not held in an intermediary IRIS Solutions account but are transferred to the bank account specified by the business.

For a SaaS platform, this model can be integrated directly into the customer journey. The user selects their bank and proceeds to its mobile or online banking environment, where they confirm the transaction.

This preserves the familiar account-to-account bank transfer while eliminating the need for customers to manually copy the IBAN, amount, and payment reference from an invoice.

Convenience and Biometric Confirmation for Monthly Subscriptions

Payment can be confirmed directly within the customer’s familiar banking environment, including through biometric authentication when supported by the customer’s bank and device. The customer does not provide card details to the SaaS platform and does not need to install an additional app to use IRIS Pay.

However, it is important to distinguish between convenient payment of a recurring obligation and an automatic recurring card payment. With Open Banking, the customer confirms the specific payment transaction within their banking environment according to the relevant payment scenario.

For SaaS companies, this is particularly suitable for B2B subscriptions and invoices where the customer is required to approve the payment anyway. Instead of receiving only an invoice containing bank details, the customer can be provided with a ready-to-use route to payment.

How Can Bulgarian Software Companies Optimize Their Cash Flow?

Bulgarian software companies can optimize cash flow by shortening the journey between invoicing, payment initiation, and the actual receipt of funds. This is particularly important for SaaS businesses because a large proportion of their operating expenses – salaries, cloud infrastructure, licences, and development – are fixed, while revenue depends on customers paying on time.

With IRIS Pay, payments can be completed in around 10 seconds when the banking infrastructure and the specific transfer support instant payments, or within the standard bank transfer timeframe.

However, optimization does not end with faster movement of funds. With the appropriate integration, payment status information can be used by an ERP, accounting, or other internal system. This reduces the time spent checking whether a particular invoice has been paid and makes it easier to associate the incoming payment with the relevant customer.

Benefits of Open Banking for Growing Software Companies

Open Banking gives growing software companies the opportunity to build a more direct, integrated, and automated payment process. Instead of keeping payment separate from the product, it can become part of the overall customer experience.

This is particularly important for SaaS platforms planning to scale. With dozens of customers, manually checking invoices may appear manageable. With hundreds or thousands of customers, the same approach begins to require significant administrative resources.

Open Banking allows payments to be initiated through a secure connection with the customer’s bank, while authentication takes place within the banking environment. For software companies, this combines a digital customer experience with the ability to integrate payments into their internal processes.

Automate the Collection of Your SaaS B2B Payments with IRIS Pay

IRIS Pay enables SaaS and software companies to turn B2B payment collection from a separate administrative task into part of the digital customer journey. The solution can be integrated into a website, application, or proprietary system, while payment links can be used for remote payments.

IRIS Pay by Click can be integrated directly into the online payment process, while IRIS Pay by Link enables businesses to create a payment link with predefined parameters that can be sent to the customer or included in a digital document. IRIS Pay also offers API integration, allowing payments and their status to be connected to the SaaS company’s systems.

This enables businesses to optimize not only the way customers pay but also the entire process surrounding the payment – from issuing the payment obligation to identifying it within the internal system.

For SaaS companies in 2026, this type of automation is key. Payment infrastructure needs to scale alongside the product, customer base, and number of B2B payments without every new transaction creating additional manual work.
