Web forms can be slightly unreliable, so if your user makes a mistake or something goes wrong instead of displaying an error pop-up, give people the option to ‘retry’ or ‘redo’ so they get a second chance and don’t have to start all over. A great example is when an upload fails, don’t make your users start the process from scratch, a retry button will avoid frustration and decrease your bounce rate.
