The reason to buy
What this saves you from building
You are not paying for a file count. You are skipping the failure handling, verification, documentation, and operational edge cases behind the feature.
Credit grants, ledger, check-in, cancellation, and settlement flows
Use an explicit data model and lifecycle instead of stitching together examples.
Failure-path tests, Docker demo, and release documentation
Keep reproducible QA and operator-facing evidence from the first integration.
What's included
Connected infrastructure, ready to adapt
- Platform, Organization, Venue, and Member workspaces with server-enforced scope
- Monthly credit grants, expiry, balance, adjustments, and ledger
- Expiring venue QR links and browser check-in with duplicate prevention

Screenshots / demo
The product is the visual.
Every frame uses synthetic fixtures. No customer data, live keys, or private environments.
Architecture
A small, inspectable workflow
Each step has a clear responsibility and can be adapted without turning the kit into a platform dependency.

Product FAQ
Before you buy

Yes. One individual or one legal entity may use it commercially under the included commercial license.
Can I modify the source?
Yes. You may modify it for permitted internal products and client deliverables.
Can I use it for client projects?
Yes, provided you do not transfer or resell the Starter Kit itself as a reusable source-code product.
Can I redistribute the Starter Kit?
No. Resale, public source distribution, public-repository publication, and repackaging as a substantially equivalent template are prohibited.
Is hosting included?
No. This is a source-code product. Hosting, deployment, and managed operation are not included.
Are updates guaranteed?
No. Future updates, compatibility releases, and indefinite maintenance are not guaranteed.
Was camera QR scanning tested on a phone?
