"I compared invoice parameters across the Tally Sundry Creditors ledger. Both bills reference PO #4811 with identical GSTIN breakdown. I recommend rejecting the pending batch disbursement and notifying the vendor."

Engine Capabilities

Three Layers of Deterministic Defense

Most software relies on either brittle keyword regexes or unpredictable LLM hallucinations. Tieot uses exact decimal arithmetic compiled in code with strict mathematical guarantees.

Rule: EXC-AP-002

Cross-Channel Duplicate Detection

Suppliers frequently submit bills via multiple channels—email attachment, supplier portal, and WhatsApp image. Slight filename or numbering variations (e.g., INV-890 vs INV/890/24) bypass standard ERP validation. Keel matches tax identifiers, exact subtotal decimals, and line-item hashes across all open batches.

Stops double-payouts before bank execution
Rule: EXC-AP-003

Dynamic Early Payment Clocks

In high-volume operations, finance teams routinely miss 2/10 Net 30 windows because approvals sit in manager inboxes until Net 30. Tieot computes the annualized yield of every vendor term (e.g. 2% in 10 days = 36.7% annualized return) and escalates expiring discounts directly to the morning priority queue.

Average capture: ₹14L to ₹48L per ₹100Cr spend
Rule: EXC-AP-001 / TDS

Statutory Withholding (TDS & MSME)

Under Indian law, contractor payments and professional fees require TDS deduction under Sections 194C, 194J, or 194Q, while MSME suppliers require settlement within 45 days. Tieot validates vendor PAN/UDYAM status and pre-computes exact statutory withholding adjustments before voucher export.
