SOTpay vs PCI-PAL: Which Payment Solution Is Right for Your Business?

Different Approaches to Secure Payments

PCI-PAL uses DTMF suppression during telephone payments: customers enter their details on their keypad, with tones masked from agents and recordings. This keeps the payment tied to the call and to agent-handled flows.

SOTpay removes the need for keypad entry altogether. Secure digital payment journeys, such as pay-by-link, let customers complete transactions on their own device, without holding the payment inside the call environment.

DTMF Is a Legacy Approach

DTMF suppression is a legacy method of securing card entry during calls. It ties payments to the telephone and to structured contact centre flows, which adds friction as customers move to digital-first payment journeys that:

• reduce dependence on telephone input
• allow customers to complete payments on their own devices
• simplify internal processes and compliance handling

Where SOTpay Delivers Greater Capability

DTMF-Free Payment Journeys

SOTpay enables businesses to take payments without requiring customers to enter card details via keypad.

Instead, secure payment links can be sent during or after a call, allowing customers to complete transactions quickly and securely.

This helps:

• reduce friction
• improve payment completion rates
• streamline the customer experience

Multi-Channel Payment Capability

PCI-PAL is confined to telephone-based environments.

SOTpay enables payments across:

• phone
• SMS
• email
• WhatsApp
• live chat
• social media

This allows businesses to collect payments wherever customer interactions take place.

Security and PCI Compliance

Both SOTpay and PCI-PAL provide PCI DSS-compliant payment environments.

SOTpay is designed to reduce PCI scope by removing sensitive card data from your business environment wherever possible. Payments are handled within secure, customer-controlled sessions, rather than passing through internal systems or call infrastructure.

This approach helps:

• reduce compliance burden
• minimise exposure to sensitive data
• simplify internal processes

Integrated Financial Workflows

SOTpay integrates directly with platforms like Xero and QuickBooks, allowing payments to be automatically matched to invoices and financial records.

This helps:

• reduce manual reconciliation
• improve reporting accuracy
• save time for finance teams

Greater Flexibility for Growing Businesses

As customer expectations evolve, businesses need more than a single payment channel.

SOTpay allows you to:

• combine telephone and digital payments
• adapt to customer preferences
• scale payment capability without adding systems

Considerations for DTMF-Based Solutions

DTMF-based platforms are built around agent-assisted card entry during calls. That confines them to:

• structured contact centre environments
• high call volumes
• payments completed during calls

They run out of road when businesses need:

• multi-channel flexibility
• faster digital payment journeys
• deeper integration into financial systems

Pricing Considerations

Both platforms offer pricing based on:

• usage
• infrastructure requirements
• payment volumes

For many businesses, total cost is influenced by:

• operational efficiency
• payment success rates
• reduction in manual processes

Which Platform Should You Choose?

Choose SOTpay if you:

• want secure telephone payments without relying on DTMF
• need multi-channel payment capability
• want integration with Xero, QuickBooks, and other systems
• want to reduce PCI scope and operational complexity
• need a future-ready payment platform

Final Verdict

PCI-PAL is confined to telephone payments using DTMF suppression, within contact centre environments.

SOTpay covers those same telephone payments and goes well beyond them, across digital channels, ecommerce, and integrated business systems.

For any business that needs more than telephony-led payments, SOTpay is the stronger and more complete platform.
