This product is fully self-serve. Everything you need is in the files you downloaded.
- Help: README.md (5-minute setup) and TROUBLESHOOTING.md (FAQ and fixes for common errors). There is no call, chat or email support.
- Refund: 14-day "works as described", requested through the checkout platform you bought on.
- Updates: fixes ship as new versions at the same download link. CHANGELOG.md lists every change.
Update plan
- PATCH release for fixes, MINOR for new options, MAJOR when inputs, outputs or setup change.
- Every release re-runs the full factory QA gate and updates CHANGELOG.md, VERSION and listing.json.
- New questions found in refund reasons or public reviews are added to TROUBLESHOOTING.md in the next version.
Regression re-test triggers
Re-run python3 run_batch.py --only payment-reminder-pro --retest when any of these happen:
- Tally or Zoho Books changes its export columns
- the UPI deep-link format changes
- Anthropic changes the Agent Skills format or upload rules
- New Python minor release
- A refund request or public review names a bug (add that case to the tests first, anonymised).
- Quarterly, even if nothing changed.
If a re-test fails, the listing goes to coming-soon until it passes again.
