Hey everyone, CA background here, did articleship, and also worked on fraud investigation cases for a while. Been building a tool that runs inside Excel for GST reconciliation, currently does 2A vs Books. Reads your file as it already is, no need to reformat anything first. Flags mismatches, duplicates, wrong tax head entries, and tells you the actual GST section behind why it's flagged.
It's 2A right now, not 2B. Know that's what actually matters for ITC these days; that's next. Doesn't change anything by itself either; you review and approve everything.
Looking for a few people who deal with this regularly to try it on a real file and tell me honestly where it's wrong. Not selling anything, just want to know if it actually holds up. Reply or message me and I will help you get it set up.
