What’s your post-launch support like after upgrade?

Two phases, then optional retainer:

Phase 1 — Stabilisation (first 14 days, included in upgrade quote):

• Daily check-ins (Slack / email) for the first 7 days, every-other-day for the next 7.
• Bug-fix work: anything that breaks because of the upgrade is included, no clock-watching.
• Performance monitoring: I track LCP, INP, error rates, conversion rate vs pre-upgrade baseline. If anything regresses, I diagnose and fix.
• Rollback button stays armed for 72 hours. After that, point-fixes only.

Phase 2 — Post-stabilisation (days 15–90, optional retainer at $1.5k–$3k/mo):

• Weekly check-in + monthly perf report.
• Capped hours for new bug-fix work or small enhancements.
• Security patch monitoring (I’ll apply 2.4.9-px patches as Adobe ships them).
• Quarterly extension audit (catch newly-incompatible extensions before they bite).

Phase 3 — Long-term ops (optional, separate engagement): Ongoing development retainer at $2.5k–$8k/mo for stores that want a dedicated Magento dev relationship. Capped hours, monthly invoice, you can scale up/down.

I don’t lock anyone into a retainer after stabilisation. Most stores at $1M–$5M GMV don’t need one; most stores above $10M GMV do. You’ll know which you are by day 30.
