# ZeroGrunt

> ZeroGrunt builds AI agents for the finance back office of teams in India: invoice booking, PO creation, vendor reconciliation, month end close, quote generation and invoice creation. For vendor invoices, Agent Zero reads every invoice as it arrives by email, matches it to the purchase order and the goods receipt, picks the vendor, GL, TDS code and cost centre from the company's past invoices, catches over-billing, duplicates and wrong GSTINs, raises debit notes the same day, and posts to the ERP or CRM (Oracle Fusion, NetSuite, SAP, Zoho Books, ERPNext, Tally, Salesforce, HubSpot). When past bookings disagree, Agent Zero asks one question by email; once approved, the answer becomes a rule for every later invoice. The finance team approves from one daily email. Pricing is per piece of work (an invoice, a purchase order), not per seat. Live in one day. SOC 2 Type II and ISO 27001.

## Guides

- [How to handle debit notes and credit notes under GST with AI](https://www.zerogrunt.ai/guides/debit-note-vs-credit-note-gst.md): Under GST, the vendor issues a credit note when the invoice was too high (goods returned, short supply, a rate above the agreed one) and a debit note when it was too low. The debit note a buyer raises for a short supply is a commercial document: it tells the vendor what you will not pay, but the GST on the invoice comes down only when the vendor issues the matching credit note.
- [How to stop paying the same vendor invoice twice, with AI](https://www.zerogrunt.ai/guides/duplicate-invoices.md): A duplicate invoice gets paid when the same invoice arrives twice in slightly different forms: once from the vendor and once forwarded by a store, or with the invoice number written differently. Check every new invoice against past invoices from the same vendor on GSTIN, a cleaned-up invoice number, date and amount together, not on the invoice number alone, and hold any close match until someone confirms it.
- [How to do GSTR-2B reconciliation with AI](https://www.zerogrunt.ai/guides/gstr-2b-reconciliation.md): GSTR-2B is the monthly statement of input tax credit available to you, built from what your vendors report in their own returns. You can claim credit only for invoices that appear in it. Each month, match it with your purchase register on vendor GSTIN, invoice number, date, taxable value and tax, then act on the gaps: chase vendors whose invoices are missing from 2B, and book invoices that appear in 2B but not in your books.
- [How to do a vendor reconciliation with AI, step by step](https://www.zerogrunt.ai/guides/vendor-reconciliation.md): A vendor reconciliation compares the vendor's statement of account with the vendor's ledger in your books, line by line, and explains every difference. Start from the same date on both, tick off the invoices, payments and notes that appear on both sides, and list what is left: invoices you have not booked, payments still in transit, TDS, credit notes and debit notes one side has not recorded, and duplicates.
- [How to do a three-way match in accounts payable with AI](https://www.zerogrunt.ai/guides/what-is-three-way-match.md): A three-way match compares three documents before an invoice is paid: the purchase order (what you agreed to buy, and at what rate), the goods receipt note (what actually arrived) and the vendor's invoice (what you are asked to pay). Pay only the quantity you received, at the rate you agreed. Anything above that is held, and you raise a debit note for the difference.
