The Process

PO, GRN, Bill—always in sync

Line-level matching compares billed quantity and price to PO and GRN. Taxes are validated Bill vs PO; GRN does not carry tax fields, avoiding false positives.

Purchase Order Validation

Base document with approved quantities, prices, and terms for comparison

Two-way when no GRN
Three-way when valid GRNs exist
Accepted GRN quantities drive 'available to bill'

Goods Receipt Note Matching

Confirms actual quantities received and accepted against PO

Validates received quantities
Tracks accepted vs rejected items
Provides audit trail

Invoice Line-Level Comparison

Transform unstructured text into structured, validated data fields

Line-level quantity and price validation
Tax rate and amount verification
Automatic exception categorization

Validation & Approval

Ensure consistent results with redundant processing capabilities

Status outcomes: MATCHED, EXCEPTION, BLOCKED

Exception Management

Exceptions you actually want to see

Exceptions are categorized to reduce noise and highlight risk.

Blocked

Critical Exceptions

High-risk issues requiring immediate attention

Overbilling risk
Quantity over-billed
Item not on PO
High-likelihood duplicates
Review

Medium Exceptions

Moderate issues requiring review

Price variance beyond tolerance
GST rate/amount/type mismatch
Info

Info Exceptions

Informational items for awareness

Items on PO missing in bill (partial billing is normal)

Status Outcomes

Clear status indicators for different exception types

MATCHED

Approve extraction as-is

EXCEPTION

Modify extracted data

BLOCKED

Send for approval

Intelligent Categorization

Reduce Exception Noise by 70%

Our intelligent exception categorization highlights only the issues that need attention, allowing your team to focus on critical exceptions rather than routine validations.

Duplicate Detection

Stop duplicates and avoid overages

We assess invoice number similarity, amounts/dates, and cumulative billed amounts vs PO value to flag risks early.

Invoice Number Similarity

Levenshtein-based similarity for invoice numbers

Validated

Amount & Date Analysis

Cross-reference amounts and dates across invoices

Flagged for Review

Cumulative Billing Check

Draft and approved bills counted in cumulative checks

Validated

GRN Analysis

Risk Assessment

Multi-Level Risk Analysis

Our intelligent detection system categorizes risks based on multiple factors to provide clear guidance on required actions.

LOW

Minor variance, likely legitimate

Small price fluctuations
Rounding differences

MEDIUM

Moderate risk requiring review

Price variance within tolerance
Similar invoice numbers

HIGH

High probability of duplicate or overbilling

Exact amount matches
Identical invoice numbers
Overbilling detected

Tolerance Configuration

Your policies, enforced automatically

Configure tolerances for price variance, quantity, dates, and GST (rate and amount).

Price Variance

Configure percentage and absolute thresholds for price differences

±5% tolerance
±$100 absolute
Per-item price checks

Quantity Tolerance

Set acceptable quantity variances from PO and GRN

±2% quantity variance
±10 units absolute
Line-specific quantities

Date Tolerance

Define acceptable date ranges for billing

±30 days from GRN
±7 days from PO
Document-wide tolerances

GST Tolerance

Configure GST rate and amount tolerances

±1% GST rate
±$50 GST amount
Item-level tax validation
