Is there a guarantee?

Yes. If the specific conflict we fixed comes back within 14 days and nothing else changed, we re-fix it at no extra charge. Every fix ships with a written root-cause note, which app injected what, in what order, and how we resolved it, so you have a record. If your conflict turns out to need a different specialist (a pure theme-Liquid bug or a hard checkout problem), we will tell you and point you to the right page rather than bill for the wrong work.
