What about post-launch support?

All tiers include 14 days of bug-fix coverage after handover — anything broken because of our build gets fixed at no extra charge. After that, two options: (1) per-incident support at our standard hourly rate (handy for one-off questions), or (2) maintenance retainer ($299–$999/month depending on extension complexity) covering Magento minor + major version compat updates, security patch verification, and minor feature requests. Marketplace-Ready tier includes 12 months of upgrade compatibility built-in.
