Batch Payment Processing for Accounting Software Users: A 2025 Guide

You’ve done the work. Invoices are approved, and suppliers are waiting. Your accounting system can generate the payment list, but now comes the part no one talks about: getting those payments actually out the door.

This is where most finance teams hit a wall.

You’re stuck either re-entering dozens of payments into your bank portal or trying to upload a CSV file that throws errors, breaks formats, or needs another round of approvals.

Instead of streamlining operations, your batch payment processing becomes a bottleneck.

The Real Cost of Manual Payouts

• Time wasted formatting or reformatting payment files
• High risk of paying the wrong supplier or entering the wrong amount
• Approvals get scattered across email threads or are delayed entirely
• Supplier trust suffers due to missed or late payments
• End-of-month reconciliation becomes a manual nightmare

And when you’re dealing with 10, 50, or even 500 payments each cycle, these problems scale fast.

Manual batch payments aren’t just inefficient. They’re risky, error-prone, and unsustainable.

What Is Batch Payment Processing?

Batch payment processing is the practice of sending multiple supplier or contractor payments in one consolidated workflow. Instead of approving each transfer separately, you bundle them and process all payments together. This approach reduces time spent, improves control, and helps avoid errors.

Traditionally, this meant exporting a payment file, usually in CSV, XML, or ISO 20022 format, from your accounting system and uploading it to your bank’s portal. But most banks aren’t designed to work smoothly with external file exports.

The result? Manual work, errors, and delays. You may spend hours checking formats, re-uploading failed files, and chasing internal approvals. Even when payments go through, you often have no real-time insight into what succeeded or failed.

How Open Banking APIs Help

Modern finance teams are moving away from manual file uploads and toward real-time, API-based payment automation using Open Banking infrastructure.

With Finexer, you don’t need to export files at all. Instead, your accounting system can send batch payment data directly through Finexer’s Open Banking API. This lets you:

• Push payment instructions securely in real time
• Authorise the entire batch with one approval
• Process payments across 99% of UK banks
• Get instant confirmation and status updates

This shift eliminates the friction between accounting systems and banking portals, replacing it with secure, compliant, and fully automated batch payment processing.
