DebiCheck is a powerful system for maximising corporate client revenue, with more than 6,000 creditors using the scheme. However, it also brings new transaction complexities, specifically mandate management, consumer adoption, and an evolving payments landscape.

From 2022 to 2024, 79% of mandate-based collections have been successful. DebiCheck is an exciting collection engine for creditors, as the procurement windows fall in the early mornings. Since collection occurs immediately after the inbound payment window, Debicheck maximises the chance of a successful transaction as funds are more likely to be present in the debtor’s account.

Before DebiCheck, Electronic Funds Transfer (EFT) was the primary collection engine for South African banks. However, this system was flawed because the only requirement to request a debit order was access to the account holder's banking information. This vulnerability led to widespread fraud, and according to media reports in 2019, it cost South African consumers R1,6 billion annually.

On the other hand, consumers would also dispute legitimate debit orders to manage their own fund availability, since scheme rules required automatic refunds before an investigation takes place.

Both scenarios posed significant challenges for banks, as fraudulent debit orders eroded consumer trust while false disputes delayed payments to corporate clients.

In response, PASA launched Authenticated Collections (AC), also known as DebiCheck.

Under the DebiCheck scheme, an entity must have a pre-approved digital mandate to collect money from a bank account. When a collection is issued, both creditor and debtor banks must verify the existence of a valid mandate before the payment is processed. If both banks confirm the mandate, the transaction is processed as specified in the mandate's terms. If one or both banks fail to verify the mandate, then it is automatically rejected before the authorisation stage.

With DebiCheck, it becomes nearly impossible to authorise fraudulent collections, and retail customers are unable to log false debit order disputes, ensuring that all stakeholders benefit from a more transparent payment ecosystem.

• Corporate clients experience improved collection rates and fewer disputes, reducing the administrative burden of chasing unpaid debts.
• Retail customers gain full control by defining collection parameters, like the date, frequency, and maximum amount, before the first payment. A transaction is automatically declined without intervention if it doesn't meet these criteria.
• Banks strengthen their brand reputation with retail customers and maintain their corporate client relationships by offering a secure environment that maximises collection success.

By addressing the needs of consumers, corporate clients, and banks alike, DebiCheck creates a more resilient financial landscape. However, the value of the solution depends on the efficiency of its implementation.

The foundation of a reliable and future-fit DebiCheck offering

Reliable mandate management

A key challenge with DebiCheck is tied to mandate management, particularly during the collection process. In addition to the standard messages needed to process a payment, each DebiCheck transaction requires mandate verification. The verification process involves sending multiple data-rich messages to corresponding creditor and debtor banks' mandate stores. These stores must then assess the collection request, ensure it has a legitimate mandate, and that the payment details correspond to the mandate specifications. Once verified, the mandate stores need to communicate the transaction request’s validity to the participating banks.

When volumes spike, the complexity of mandate management places significant strain on a bank's systems. Adding multiple collection mechanisms only worsens this strain.

To ensure stability and reduce strain on core systems, your modern mandate store must process data-rich messages effectively, quickly, and reliably, thereby ensuring transaction success and reducing bottlenecks.

Cloud-native architecture allows you to decouple mandate and collection management systems, ensuring stability regardless of scale.

A stable DebiCheck solution requires a full understanding of the transaction lifecycle. Therefore, to identify and resolve the root cause of transaction failures and enable effective troubleshooting, it must be designed with full observability.

Increased adoption

DebiCheck was the solution to fraudulent EFT collections and disputes; however, issues arose in confirming valid mandates. Consumers lacked awareness of what digital mandates were or how to confirm them. By 2022, retail customers had authorised only 59% of issued mandates.

To address lagging authentication, PASA introduced the Registered Mandate Service (RMS), which allowed creditors to collect against mandates without authorisation; however, retail consumers still needed to be notified about the mandate, and could dispute it to prevent future collections. Despite the introduction of RMS, mandate authorisation rates have only grown to 62% in 2024.

These challenges present an exciting opportunity for banks to differentiate their collection services. Creditor banks can offer training for corporate client sales teams to ensure mandate verification when finalising a sale.

Additionally, banks can optimise the user verification journey in their app to increase the likelihood that their retail customers accept verifications. The improved user experience can serve as a proof point for corporate clients, benchmarked against the industry average, showing that your bank values and prioritises a successful collection engine.

Rapidly adapt to scheme changes

In 2025, RMS became a formalised collection mechanism known as Registered Mandate (RM). While these efforts succeeded in mitigating fraud and enabling collections, they introduced complexity and system strain for banks, who now had to manage three distinct collection mechanisms with different rules and requirements.

Consequently, bank collections are stratified, requiring more resources for maintenance, optimisation, and product development. Additionally, there is greater strain during collection periods, as they now have to be managed across three different solutions.

DebiCheck, RM, and EFT each play distinct roles in collections. To optimise your collection business, it is critical to position each scheme appropriately by understanding what they do well and their limitations.

Banks can ensure corporate client satisfaction by identifying optimal collection processing windows through automated scheduling.

By modularly replacing outdated or unfit components of their existing DebiCheck solution, banks can ensure operational stability while eliminating technical debt. Strategically shifting to future-fit systems ensures stability over time as volumes continue to scale, corporate client needs shift, and scheme rules change.

A stable modernisation approach is to use cloud-native architecture to deploy changes iteratively.

Achieve operational calm with a proven software partner

DebiCheck fosters corporate client trust by providing the reliability needed to safeguard their revenue while giving retail customers transparent control. When a stable, consolidated system manages mandates efficiently, collection rates improve, and disputes naturally decrease. To maintain stability needed to protect corporate client revenue, DebiCheck infrastructure requires ISO 20022-native processing and real-time visibility.

Creating a standout DebiCheck solution requires proven expertise and an understanding of the nuances of South Africa’s payments ecosystem. By working with payment software providers like Electrum, banks can leverage purpose-built foundations that evolve without introducing complexity, allowing them to focus on building functionalities that deliver value to their corporate clients.
