1. Pre-purchase checklist

Item	Verify
Processor is NMI on MID paperwork	ISO branding ≠ different API
Sandbox / test gateway credentials	From ISO or NMI portal
Integration type matches product page	Hosted vs direct API
USD settlement plan documented	Multi-currency if applicable
WooCommerce + PHP within requirements	Product page minimums

Use how to evaluate payment gateway plugins and WooCommerce payment gateway integration checklist for broader validation.

2. License and renewal expectations

Annual license covers updates and support per product terms.
Expired licenses may leave production on unpatched code when Woo or NMI changes endpoints.
Budget renewals using payment gateway TCO framing.
Support typically covers documented plugin behavior—not unlimited third-party theme conflicts.

3. Sandbox test matrix

Execute on staging before live keys:

Test	Pass criteria
Approved test transaction	Correct paid/processing status
Decline	Safe failure UX; no false “completed”
Early browser close	Webhook/IPN completes order
Partial refund in Woo admin	Visible in NMI reporting
Auth + capture (if used)	Operations match finance SOP
Subscription renewal (if applicable)	Second charge without manual intervention

Guides: how to test your payment gateway like a pro, staging vs production testing, PCI-safe logging.

4. Purchase and install workflow

5. Post-purchase operations
