For: GST officers · Chartered Accountants · finance teams
Why it exists
Fast, accurate, audit-ready.
GST officers, CAs and finance teams spend days stitching portal exports together before they can even start an audit. GSTNXT takes the raw portal files, Excel or ZIP, up to 400 at once, and does the stitching.
The parser is label-based, so it survives the portal's layout shifts. Output is a single audit-ready workbook: per-section master sheets, a compiled 3B summary, GSTR-1 vs 3B and 2A vs 3B difference sheets, and a colour-coded validation summary.
Jobs survive refresh, progress is visible stage by stage, downloads are owner-scoped and auto-purged. Built for officers as much as practitioners.
