Overview

Blend partnered with AWS to help Progresión implement a mass payment and collection system that automates payroll, supplier disbursements, and receivables at scale. The solution leverages unique transaction references to enable real-time reconciliation while embedding identity controls, API protection, encryption, and fraud monitoring to ensure the security and reliability of large-scale financial operations. By modernizing payments infrastructure, Progresión expanded secure digital access for businesses and underserved communities while reducing costs and accelerating cash flow.

Challenge

  • Manual Matching: Managing thousands of small payments across multiple banks required manual reconciliation, creating delays, errors, and heavy administrative overhead.
  • Reconciliation Gaps: Missing or inconsistent payment references limited financial visibility and audit readiness.
  • ACH Dependence: Reliance on Colombia’s ACH system delayed cash flow and increased operational costs, restricting real-time liquidity management.
  • Security Vulnerabilities: Without automated identity controls, encryption, API protection, and fraud monitoring, mass collections faced risks in accuracy, integrity, and regulatory compliance.

Solution

Progresión deployed a secure, cloud-native platform on AWS that automates mass disbursements and collections, strengthens compliance, and ensures accurate real-time reconciliation.

  • Secure Web Access (Public Subnet): Amazon CloudFront accelerates user access with TLS encryption, AWS WAF protects against malicious traffic, and Application Load Balancer (ALB) ensures reliable routing. Endpoints are secured via AWS Certificate Manager (ACM).
  • Automated Payment & Collection Engine (Private Subnet): AWS Lambda and AWS Step Functions process payroll, supplier payments, and mass collections. Unique identifiers ensure precise reconciliation.
  • Intelligent Reconciliation Module (Private Subnet): Amazon DynamoDB maps payments to payers in real time, reducing mismatches and strengthening financial accuracy.
  • Application Security & Compliance: Amazon Inspector scans workloads for vulnerabilities, AWS Config enforces secure baselines, and AWS Security Hub centralizes compliance findings.
  • Storage & Data Protection: Amazon S3 retains logs and compliance records, Amazon RDS secures databases with encryption in transit and at rest, and AWS KMS manages encryption keys.
  • Multi-Bank Interconnectivity & ACH Processing: Amazon SQS enables asynchronous interbank processing, while AWS VPN Site-to-Site ensures secure connections.
  • Real-Time Monitoring & Fraud Detection: Amazon CloudWatch, AWS CloudTrail, and AWS Config provide full visibility and auditability, while Amazon GuardDuty and AWS Security Hub detect anomalies and centralize fraud-prevention insights.

Impact

The new AWS-powered platform allowed Progresión to streamline payment operations and expand financial access across multiple channels:

  • Eliminated settlement delays, enabling payments to clear in near real time.
  • Simplified micro-payment management, freeing resources for higher-value activities.
  • Ensured continuous access to financial services across peer-to-peer and retail environments.
  • Expanded secure access to digital payments for underserved and unbanked communities.
  • Built trust through embedded identity controls, encryption, API protection, and fraud monitoring.
