How much does it cost to fix a Magento bug after an upgrade?

Every project gets a fixed written quote. Send a short brief on WhatsApp and I reply within one working day with scope, price and timeline.

• Quick Fix (~4h): one well-defined post-upgrade bug, such as a single fatal or one broken page.
• Bug-Fix Sprint (~20h): a batch of bugs, or one gnarly root cause like a composer deadlock or a removed-API cascade, with regression tests.
• Contact me for a quote.

You see the quote before any work starts. No silent per-hour billing.
