Fully autonomous AP & GL posting with zero-tolerance validation in SAP B1.
BRC deployed a single AI automation platform to handle six high-volume, document-heavy financial workflows GRN invoicing, landed cost reconciliation, bulk GL entries, and monthly salary postings all posting directly into SAP Business One with no manual approval gate.
Six high-volume workflows, all processed by hand
BRC runs a high volume of recurring financial postings in SAP Business One: vendor invoices matched against Goods Receipt Notes, import Landed Cost documents from three different customs brokers, bulk journal entries for mobile, transport, and electricity payments, and monthly salary invoices from manpower service providers across every branch.
We built a single automation platform the BRC GRN & GL Automation System that reads source documents (PDFs, Excel workbooks, bank statements), validates them against SAP's own records, and posts directly to SAP B1. No module posts anything until it has passed a strict, computationally-enforced set of checks.

The Challenge
Each posting workflow required cross-referencing multiple documents by hand commercial invoices, GRNs, customs Bayan declarations, bank statements, and routing tables across six very different processes:
Vendor invoices manually matched line-by-line against open GRNs before AP posting
Three customs brokers with different invoice structures, reconciled against SAP Landed Cost by hand
Bulk telecom payments reconciled between SNB bank statements and per-subscriber Excel sheets
Transport and electricity bills manually routed to correct GL accounts and cost centers
Manpower salary invoices manually calculated and grouped per branch, division, and cost center
No centralized visibility when a document failed to process correctly
At this volume, manual processing meant slower postings, inconsistent handling between staff, and a real risk of data-entry error reaching SAP directly.
Four structured phases, minimal disruption
Workflow Discovery
Each of the six posting workflows was mapped end-to-end source documents, SAP data dependencies, validation rules, and failure modes to define exactly what the automation platform needed to enforce.
Module Architecture
Six dedicated modules were built on a shared validate-then-post pipeline: GRN Invoice, Landed Cost (Sultan, Excellence, Alwatanya), Mobile GL, Transport GL, Electricity GL, and MPS Salary Invoicing.
Validation Engine Build
Each module received its own sequential validation chain. For GRN Invoicing alone, five hard-fail checks run before an AP Invoice is ever created including zero-percent amount tolerance and quantity cap enforcement.
SAP Integration & Governance
Direct SAP B1 posting was wired for all six modules, with duplicate detection, role-based access control, posting date rules, and a live operations dashboard surfacing every failure with reason, step, and timestamp.
The Solution
One automation platform, six modules, each posting directly to SAP Business One through the same validate-then-post discipline: Upload → Parse → Reconcile / Validate → Build Payload → Post to SAP → Verify.
GRN Invoice Automation (A)
- Reads vendor PDF invoices automatically
- Fetches matching SAP GRN records
- Runs 5 sequential validation checks
- Duplicate check on CardCode + invoice number
- Posts AP Invoice directly to SAP B1
No invoice is posted until it clears all five hard-fail checks vendor code, invoice validity, line matching, quantity cap, and amount tolerance.
Landed Cost Processing (B)
- Broker-specific logic for Sultan, Excellence, Alwatanya
- Reconciles against SAP Landed Cost document
- Calculates customs duty, freight, and incidentals
- Posts up to four AP Invoices per import
- Auto-reconciled amounts, no manual entry
Each customs broker has a different invoice structure; the module handles all three formats within a single reconciliation pipeline.
GL Bulk Automation (C.1–C.3)
- Mobile/Telecom: SNB bank PDF vs. Excel allocation
- Posts one balanced Journal Entry per transaction
- Transport: Najd delivery note extraction & SAP PI
- Electricity: SEC meter routing to GL, cost center, division
- Keyed on unique Bank Transaction ID to block duplicates
Three separate GL workflows mobile, transport, electricity unified under one bulk posting discipline with automated reconciliation and duplicate protection.
MPS Manpower Salary Invoicing (C.4)
- Parses multi-sheet monthly salary workbooks
- Groups costs by Division and Cost Center
- Posts one Service Purchase Invoice per branch
- Handles multiple manpower providers
- Automated monthly cycle no manual calculation
What previously required manual per-branch calculation across multiple providers now runs in one consistent posting cycle every month.
Validation in Practice GRN Invoicing
The GRN Invoice module alone runs five sequential checks before an AP Invoice is ever created. Any single failure is a hard stop the document is blocked, not posted incorrectly:
Wrong extractions cannot become wrong postings a bad vendor code, amount, or quantity fails validation instead of posting incorrectly.
Governance at a Glance
The platform's reliability comes from its governance design, not from trusting the AI's extraction blindly. Every module is built to the same standard:
100% of modules with built-in duplicate detection
5 sequential checks before every GRN posting
Full audit trail on every posting, every module
Fully autonomous, SAP-native posting with no manual approval gate
Governance figures reflect the platform's enforcement configuration and design constraints not statistical estimates.
Before vs After
Business Impact
Six previously manual, document-heavy workflows now run through one consistent pipeline reducing the time and staff attention needed to keep AP, landed cost, bulk GL, and salary postings current in SAP.
Because validation is strict and computational, an AI extraction error becomes a blocked posting, not a wrong one in SAP the finance team resubmits a corrected document instead of chasing down a bad entry after the fact.
The system is built to scale: new brokers, branches, or bill types extend the same validate-then-post pattern rather than requiring a new manual process.
Why It's Reliable
The platform is designed as a fully autonomous agent but reliability comes from strict, auditable controls, not from trust in the AI alone. Core capabilities include:
"The system handles postings we used to process manually across multiple staff members. Validation catches every mismatch before it reaches SAP, so our finance team spends time reviewing exceptions not chasing down incorrect entries."
