It really depends on the code. To find a CSS bug, yes easy peasy. To find a logic hole in a payment integration of what someone has missed or should have implemented but didn't (eg webhooks), then this requires a lot more time and the developer basically has to sit down properly to work out exactly what should have been implemented / how they would have developed it, and then cross-check it against what has been done, otherwise you won't be able to easily find those logical holes which effectively are bugs, just not simple code bugs like a missing semicolon.
