Overview

A tailored investment solutions firm in Colombia partnered with Blend to implement an automated payment platform that could streamline payroll and supplier disbursements while ensuring compliance.‍

Challenge

The client serves customers with high-value financial operations, requiring efficient payment execution. However, Colombia’s slow and expensive ACH system, combined with the need to coordinate across multiple banks, created bottlenecks. Before processing payments, the client also had to meet complex tax and regulatory obligations, manually adjusting deductions, invoices, and documentation.
This manual process led to delays, errors, and inefficiencies in liquidity management, compliance, and reconciliation, making large-scale operations costly and time-consuming.

Solution

Multi-bank payment platform that integrates a pre-payment module to deduct taxes, invoices, and regulatory obligations before processing transactions.
