Compliance Deadline: November 2026

ISO 20022 · Payment Transformation

Altimetrik's ISO 20022 Migration Accelerator

We get you to ISO 20022 compliance before November 2026
The global payments network just went through its biggest upgrade in decades. Banks completed the November 2025 SWIFT compliance milestone. The infrastructure is live, and the new payment language is in place.
Now the work moves to the corporate side. From November 2026, every company that sends cross-border payment instructions must use ISO 20022-aligned formats. The old formats will not be accepted. For banks, that means thousands of clients still on legacy systems, all at risk of having their payments rejected. For corporate clients, it means a compliance deadline with real operational consequences that requires action now.
Altimetrik's ISO 20022 Accelerator is built for both. It connects to your existing systems, converts legacy payment files into bank-accepted ISO 20022 messages, and does it without replacing a single system you use today. Whether you come to us through your bank or directly, the path to compliance is the same.

Built for Banks. Built for Corporates.

For Banks

Help your clients comply without taking on the delivery burden.

A single bank can have thousands of corporate clients still on legacy payment formats. Banks that move early protect those relationships and gain a first-mover advantage before competitors engage the same client base. Altimetrik works with each corporate client directly. You introduce the program, and we handle everything that follows. No development cost, no delivery burden, no implementation responsibility on your team.

For Corporate Clients

Get compliant before your payments stop

From November 2026, the payment instructions generated by your ERP, treasury system, or vendor management platform must be in ISO 20022-aligned formats. The formats your systems currently produce will not be accepted. Altimetrik's accelerator sits on top of your existing setup, handles the conversion automatically, and keeps your teams working exactly as they do today. You can come to us directly or through your bank.

Process

How Does It Work?

Altimetrik follows a repeatable four-step model designed for fast turnaround with minimal disruption.

Discovery

We confirm your current payment formats, the systems involved, and what your bank requires before any configuration begins

Configuration

The plug-in is mapped to your source files. Legacy MT101 (Request for
Transfer) or proprietary initiation messages are translated to their equivalent Pain.001
messages (Customer Credit Transfer Initiation).

Testing

Every output is validated against CBPR+ guidelines and tested against the
bank's acceptance criteria before go-live.

Go-live

The connector is deployed to production. Business users notice nothing has
changed.

Integrations

What Does It Connect To?

  • Vendor management systems
  • Custom and proprietary formats

FAQ

Frequently Asked Questions

Banks completed their own ISO 20022 migration in November 2025. From November 2026, corporate clients must convert their payment initiation formats to bank-accepted ISO 20022 messages. Any payment sent in the old format after that date will not be accepted on the SWIFT network.

No. The accelerator integrates with your existing systems with minimal disruption to your business workflows. Nothing gets replaced or rewritten. Your teams carry on exactly as before.

This works well for companies that:

  • Send cross-border payments using file uploads or APIs from an ERP or treasury system
  • Currently generate payment files in legacy formats
  • Do not have in-house ISO 20022 expertise or a dedicated integration team
  • Need external support to complement their in-house teams and expedite the process
  • Need to be compliant quickly and with minimal disruption

The plug-in uses config-driven mapping and works with legacy MT101 files, ERP-generated formats, CSV-based payment files, and other custom and proprietary formats. The specific formats your systems produce are confirmed during the discovery phase.

Corporate clients can engage Altimetrik directly or through their bank. When a bank introduces a client to the program, the bank is the referring institution, and Altimetrik handles everything that follows. Corporate clients who come to Altimetrik independently work with us the same way. Both paths follow the same implementation process.

Altimetrik follows a repeatable delivery sequence:

  • Client qualification and discovery
  • Fit assessment and gap analysis
  • Configuration and mapping
  • Testing with the bank's onboarding team
  • Go-live readiness review
  • Production deployment
  • Hypercare and stabilization

Ongoing upgrade support is available for clients who need it. Updates required by rulebook or scheme-version changes are handled separately from the initial conversion and priced accordingly.
