Performance at a Glance
Audit‑Ready Compliance
Key Features
GST‑First Validation
Validation based on Vendor & Buyer GST filing history. If the vendor has not generated an e-invoice, AP posting is blocked to avoid input tax credit issues.
– HSN code & value matching before posting
– GST filing history verification
– Automatic exception flagging with corrective notes
One‑Click Ready‑to‑Post Screen
A smart dashboard that shows all Ready-to-Post invoices, highlighting validation errors on screen. Post with a single click.
– On‑screen error messages (GST mismatch, HSN mismatch, missing e‑invoice)
– Bulk select, post, or undo options
– Audit trail and approval integration
Auto AP Posting & TDS Capture
Withholding Tax(TDS) is automatically captured from BP Master. Supports both Auto-Post and Manual Post Modes.
– TDS slab and PAN/TAN checks from BP master
– Automatic journal creation with tax breakups
– Configurable posting rules per company/branch
Faster Posting
During GRPO creation, the system validates HSN, total value, rates, and quantities against PO. Any mismatch is blocked or raised as an exception.
– Line‑level quantity and rate validation
– HSN consistency across PO → GRPO → Invoice
– Configurable tolerance percentages
