What Is A Cross-Border Payment Aggregator Service?

A cross-border payment aggregator (PA-CB) is a financial service provider that bundles multiple payment methods, currencies, and compliance tools into one platform. It enables businesses to accept international payments by simplifying processes that would otherwise require direct partnerships with foreign banks.

These aggregators help merchants handle online payments across borders while ensuring AML compliance and offering functions such as escrow, FX conversion, and fraud detection. In Latin America, PA-CBs play a crucial role in e-commerce growth by bridging financial gaps between countries and providing infrastructure for underserved markets.

This guide explains how PA-CBs work, how they differ from gateways, and why they are essential for global trade. For example, platforms like Order Express deliver the infrastructure businesses need to expand internationally.

Understanding Payment Aggregators and Gateways

To navigate cross-border e-commerce, it’s essential to understand the difference between payment aggregators and payment gateways. While both enable digital transactions, they serve distinct roles in how payments are processed, secured, and managed. This section breaks down what each term means, how they function in Latin American markets, and why businesses often rely on both to streamline global payments.

What is a Payment Aggregator (PA)?

A Payment Aggregator is a third-party service provider. It allows businesses to accept online payments through websites or mobile apps. These aggregators enable transactions via credit cards, debit cards, e-wallets, and bank transfers. Merchants do not need a direct relationship with a bank. The aggregator collects payments on their behalf and settles the funds later. In Latin America, licensed non-bank PAs are subject to local regulations and often partner with financial institutions to offer services such as check cashing.

PA-CBs simplify payment setup for businesses and improve their chances of growing online. They typically provide a unified dashboard, invoicing tools, analytics, and fraud detection. This bundling of features makes them a preferred option for startups and mid-sized merchants in Latin American countries.

What is a Payment Gateway?

A payment gateway is a software platform. It links the customer’s payment source to the merchant’s payment portal. It authorizes transactions and ensures secure transfer of funds. Payment gateways support multiple channels like credit cards, debit cards, digital wallets, and bank transfers. In Latin America, common gateways include regional platforms that integrate with local banks and payment networks. These platforms ensure transaction approval, fraud checks, and encryption.

Modern gateways also support real-time processing, tokenization, and mobile payments. As mobile internet access grows in Latin America, gateways must adapt to mobile-first environments. Integrating with regional gateways ensures compliance with local transaction rules and banking networks.

Payment Aggregator vs. Payment Gateway

A payment gateway is a tool for processing transactions. A payment aggregator manages multiple gateways and simplifies integration for merchants. Gateways focus on transaction approval and security. Aggregators focus on managing relationships, settlements, and compliance. Most aggregators operate their own gateways to provide full-service options. In Latin America, aggregators often work with regional banks and fintech partners to offer money transfer functionality and more.

PA-CBs often act as one-stop solutions, bundling multiple services like onboarding, analytics, FX conversion, and customer support. This helps merchants streamline operations and focus on sales and logistics.

Compliance and Operational Models

Operating as a cross-border payment aggregator requires strict adherence to regulatory and compliance frameworks. From FinCEN registration in the U.S. to anti-money laundering protocols in Latin America, PA-CBs must navigate a complex landscape of legal obligations. This section explores the compliance standards, authorization models, governance structures, and due diligence practices that ensure secure, legal, and transparent operations across borders.

Current Compliance Standards

PA-CBs must meet financial and compliance criteria in the jurisdictions they serve. In the U.S., they must register with FinCEN and comply with the Bank Secrecy Act. Any transaction or pattern that totals 2,000 USD or more (5,000 USD if detected through record review) triggers a Suspicious Activity Report, which must be filed within 30 calendar days of detection; follow-up SARs are due between 120 and 150 days if the activity continues. Currency Transaction Reports are mandatory for any cash-in or cash-out activity that exceeds an aggregated 10,000 USD in a single business day; CTRs must be filed within 15 calendar days. PA-CBs are also required to renew their MSB registration every two years and maintain electronic records of all updates, including ownership changes and business structure modifications, through the BSA E-Filing System.

For Latin American corridors, they must partner with regulated entities in each country. These partnerships ensure compliance with anti-money laundering (AML) and counter-terrorist financing (CTF) rules. Aggregators must perform customer due diligence (CDD) and maintain transaction monitoring systems.

In addition, compliance teams must track regulatory updates, conduct regular staff training, and coordinate with external auditors. These processes ensure that risk exposures are minimized and oversight bodies are satisfied with internal controls.

Authorization Models

PA-CBs may be categorized as Export Only, Import Only, or both. In Latin America, Export Only PA-CBs help Latin merchants receive payments from the U.S. Import Only PA-CBs help consumers in Latin America buy from global sellers. Entities providing both import and export services must keep clear separation of transaction flows and reporting. These categorizations are essential to manage risks and meet regulatory standards in both regions. They also impact whether remittance transfer rules under Regulation E apply.

Clear categorization also impacts FX reporting, VAT reconciliation, and risk-scoring logic that guides AML workflows. It ensures uniformity and consistency across operational units.

Governance and Risk Framework

All PA-CBs must establish strong governance frameworks. They must include internal controls, risk management, and fraud prevention. This is particularly important when handling high-risk transactions or operating in countries with limited financial infrastructure. PA-CBs must onboard merchants through a verified process. They should check for restricted goods and monitor high-value purchases. Dispute management and customer support processes must be clear and accessible.

Tools like Chainalysis monitor suspicious blockchain activity, helping PA-CBs detect fraud in real time. Beyond this, aggregators are expected to conduct enterprise-wide risk assessments, segmenting threats by geography, payment channel, merchant category, and transaction value. Boards of directors must be involved in approving risk appetite and escalation protocols.

Due Diligence Requirements

PA-CBs must perform Know Your Customer checks on all merchants and buyers when transactions meet or exceed 3,000 USD, or lower state-specific limits where applicable, in addition to routine onboarding. In the U.S., this includes ID verification and screening against OFAC lists. In Latin America, local regulations vary, but most require similar identity checks and documentation. Enhanced due diligence begins at the 2,000 USD SAR trigger, remains in force at the 3,000 USD monetary-instrument trigger, and is always applied to any transaction that reaches the 10,000 USD CTR threshold. EDD includes source-of-funds verification and buyer identity validation, often linked to virtual-currency and regulatory limits.

Due diligence also includes ongoing monitoring. Transactions must be reviewed to identify patterns that deviate from the norm. Any inconsistencies should trigger further investigation or suspension of service.

Account Structures and Settlement Flows

Secure and transparent account structures are the backbone of cross-border payment aggregation. PA-CBs must follow strict protocols for managing escrow accounts, processing settlements, and separating import and export flows. This section outlines how aggregators handle fund movement, enforce regulatory safeguards, and structure accounts to prevent fraud, enable due diligence, and comply with U.S. and Latin American financial regulations.

Escrow and Settlement Accounts

To protect customers and merchants, PA-CBs must use escrow accounts. These accounts must be with licensed banks. Funds must be settled promptly and in line with agreed timelines. In the U.S., settlement timelines are tied to delivery confirmation or refund windows. Latin American counterparts must follow similar structures. Funds should not be used for lending or investment. Escrow mechanisms help reduce risk of fraud or bankruptcy.

Escrow banks are forbidden from lending against these funds. Under internal BSA/AML policies, PA-CBs must ensure that escrow funds are not pledged, used as collateral, or accessed for any unauthorized purpose. These protections align with global trade regulations such as those outlined by Travel.State.Gov. Segregated escrow accounts also prevent commingling of merchant and platform funds.

Import Only PA-CBs

Import-focused PA-CBs in Latin America must ensure all import payments follow legal routes. They must only support legal, unrestricted goods. Payments from consumers are collected into escrow accounts. These are transferred to foreign merchants after goods are confirmed. Import PA-CBs may onboard international merchants or work with global platforms. Due diligence on foreign merchants is mandatory. If the transaction is high-value, buyer due diligence is also required.

They may enable users to purchase airline tickets easily while ensuring compliance with travel and customs requirements. Identity checks may include standards set by the TSA.

Export Only PA-CBs

Export-focused PA-CBs allow Latin American merchants to receive cross-border payments. These aggregators maintain export settlement accounts in both USD and local currency. They must validate the identity of each merchant onboarded. Only registered, compliant businesses can be paid. Export PA-CBs must also prevent restricted goods from being sold abroad. Proceeds are transferred only to verified merchant accounts. Currencies are converted according to local FX regulations.

These platforms are also expanding into Bitcoin and crypto payment support, allowing merchants to access new audiences using digital assets or tools.

Import and Export PA-CBs

PA-CBs offering both import and export services must maintain clear operational boundaries. They must use separate escrow and settlement accounts for each service. Import Collection Accounts (ICA) and Export Collection Accounts (ECA) should not be mixed. Each set of accounts must follow local laws, AML checks, and audit protocols. Entities must ensure compliance with U.S. and Latin American regulations. Dual-service PA-CBs must maintain accurate logs and reconciliations.

Additionally, dual-licensed entities often adopt internal firewalls between teams, with separate compliance officers and reporting lines. This creates operational integrity while meeting legal expectations.

Payment Instruments and Regulatory Requirements  

• Escrow Mechanisms: Escrow accounts are a safeguard in payment aggregation. They hold customer funds until delivery is confirmed. Escrow banks must be licensed and regulated. PA-CBs must remit funds into escrow accounts immediately after receiving payment. The amount in escrow must always match the balance owed to merchants. This prevents misuse or diversion of funds. Well-structured escrow accounts build trust between buyers and sellers. Some platforms even offer services like courier services to support delivery processes.
• Settlement Finality: Settlement finality is when a payment becomes irreversible. For PA-CBs, this means the point where funds move from escrow to the merchant. The timing depends on the transaction agreement. If the aggregator is responsible for delivery, settlement must happen within one day of shipment confirmation. If the merchant is responsible, settlement must happen within one day of delivery confirmation.
• Settlement Models: Each aggregator must define clear settlement models. These models must be based on contract terms with merchants. PAs should offer flexibility to reflect local market practices. However, rules must be consistent and documented. Deferred settlement models must meet regulatory obligations.
• Transaction Flows: A typical payment flow starts with a customer placing an order. The PA processes the payment and collects the amount. It stores the funds in an escrow account. The merchant receives notification and ships the goods. After delivery is confirmed or refund periods expire, the PA settles the amount with the merchant. For consumers seeking guidance on cross-border payments, resources like ways to send money offer helpful comparisons.

Instrument-Specific Flows

PA-CBs must adapt to different payment instruments. Cards involve acquiring banks and require PCI compliance. Wallets involve KYC and local electronic money rules. Bank transfers require clear settlement windows and AML checks. Each instrument introduces unique regulatory and operational requirements. PA-CBs must maintain dynamic compliance frameworks to address each one.

Platforms offering support for multiple instruments, such as vehicle services for verification — reduce friction and expand user access. Some platforms educate merchants using blockchain learning resources.

AML and Reporting Obligations

PA-CBs must monitor transactions for suspicious activity and file Suspicious Activity Reports when a transaction or pattern meets the 2,000 USD trigger (5,000 USD if found during record review). The initial SAR is due within 30 days; continuing SARs must be filed within 60 days after the initial 90-day review if activity persists. Currency Transaction Reports are required whenever cash-in or cash-out totals exceed 10,000 USD in a single day and must be filed within 15 days. Front-line staff must be trained to detect structuring attempts aimed at evading thresholds and must never disclose SAR filings or related investigations to customers or unauthorized parties. Aggregators must track customer behavior, monitor transaction patterns, maintain watch-lists, and screen names against OFAC and other sanctions lists. In Latin America, local laws may also require reporting to central banks or Financial Intelligence Units.

The ability to generate instant reports and adopt paytech innovations can streamline this process.

Partner Banks and Institutions

PA-CBs must work with trusted banking partners. These include acquiring banks, settlement banks, and FX service providers. All partners must be regulated and AML compliant. Contracts must include clauses for data sharing, dispute resolution, and reporting. For further assistance or inquiries, users can contact us anytime.

Technology and Infrastructure

PA-CBs must invest in scalable and secure infrastructure. Platforms must be PCI-DSS compliant and support encrypted data transfer. Monitoring systems must detect fraud, manage chargebacks, and automate settlement cycles. Integration with payment gateways and banks should be seamless.

Redundancy, uptime, and data protection protocols must be rigorously documented. Cloud-hosted platforms with containerized architectures help ensure rapid failover and geographic coverage.

Customer Experience and Dispute Resolution

PA-CBs must ensure positive customer experience. Platforms should offer transparent terms, multilingual support, and clear refund policies. Dispute resolution processes must be easy to access. Refunds, chargebacks, and complaints must be handled within regulatory timelines.

Proactive engagement, including chatbots, multilingual support teams, and real-time tracking tools — helps build trust. Mobile-friendly interfaces and tiered support channels also boost customer satisfaction.
