How it works
From paper pile to filed GSTR — in three steps.
Upload or forward
Drop in a PDF, scan, or photo of an invoice — or forward it to your Zerenzo inbox. OCR handles even crinkled prints.
AI reconciles GST
We validate GSTINs, check CGST/SGST/IGST math, match line items to your books, and flag every mismatch.
Export clean reports
Download GSTR-ready summaries, mismatch logs, and journal entries — push straight to Tally or Zoho Books.
Features
Built for the messy reality of Indian accounts payable.
Invoice OCR that handles real paper
Scans, photos, PDFs, even thermal prints. Extracts every line item, HSN code, and tax field.
Mismatch detection
Catches wrong CGST/SGST splits, broken GSTINs, line totals that don't sum, and inter-state IGST errors.
Auto-reconciliation
Matches purchases against GSTR-2B and your books. No more manual ticking in Excel.
Reports your CA loves
Monthly GSTR summaries, ITC eligibility, and a clean mismatch log — exportable to Excel or Tally.
Audit-ready trail
Every change, every override, every flag — logged and exportable. Sleep through scrutiny notices.
Plugs into your stack
Tally, Zoho Books, Vyapar, Gmail forwarding. Zerenzo fits where you already work.
From the beta
Early SMEs and CA firms are already filing faster.
"We used to spend three days every month reconciling vendor invoices. Zerenzo's beta cut that to an afternoon. The GSTIN check alone has caught two wrong claims."
"I handle 40+ SME clients. Having a tool that pre-flags CGST/SGST errors before files hit my desk is genuinely a productivity unlock during return season."
"Honest, no-BS product. It does one thing — invoice reconciliation — and does it better than the bloated ERPs we tried."
About
Made by founders who lost weekends to GSTR-3B.
Zerenzo started inside our own e-commerce business. Every month we shipped a pile of vendor invoices to our CA, every month something was wrong — a missing GSTIN, a wrong CGST split, a line item that didn't sum. Spreadsheets weren't going to fix it.
We built Zerenzo so any Indian SME — from a 5-person D2C brand to a ₹50 cr distributor — can close their books in hours instead of days. Our mission is simple: collapse compliance work to its absolute minimum, and give that time back to the business.
