Collaboration Paths
Choose Your Path
Every contribution moves the standard forward. Here are the ways you can make a difference.
Funding
Help sustain development, infrastructure, and community events. Your sponsorship invests in an open, vendor-neutral future for digital receipts.
Pilot Projects
Test in real POS and bookkeeping environments. We need POS vendors, retailers, bookkeeping providers, and app developers to validate the spec against real-world workflows.
Code Contributions
Build SDKs, reference implementations, or validation tools. Every pull request strengthens the ecosystem. All code is Apache 2.0.
Spread the Word
Present at meetups, write blog posts, share on social media. Awareness drives adoption — every conversation counts.
Feedback & Review
Review the specification, file GitHub issues, test implementations. Critical feedback from developers, merchants, and regulators makes robust.
Standards & Policy
Help align with ISO 20022, GS1, and EU digital receipt regulations. Connect us with standards bodies and policymakers.
