A regional supermarket chain with hundreds of outlets processed over 20,000 supplier invoices per month, often received in multiple formats PDFs, scans, emails, and handwritten notes. Each invoice had to be manually read, validated, and entered into the ERP. This overwhelmed the AP team and introduced a wide range of issues: slow processing, errors, duplicates, delayed payments, and compliance risks. The client needed a smarter, AI-first approach that didn’t rely on static OCR templates but could read, understand, and validate invoices contextually.  

The Challenge: Unstructured, Unscalable, Unreliable

The client’s accounts payable process was struggling with high volumes of diverse invoices, leading to delays, errors, and operational inefficiencies.

Key pain points included:

• Invoice Format Diversity: Hundreds of unique invoice formats with no standardization made data extraction challenging.

• Line-Level & Tax Data Errors: Accurate capture of item details, quantities, and taxes was difficult, resulting in frequent errors.

• Mismatch with POs and GRNs: Reconciliation issues led to delays in approvals and payments.

• Lack of Real-Time Visibility: Finance teams had no up-to-date view of invoice exceptions or bottlenecks.

• Scalability Issues: Seasonal or quarterly spikes in invoices overwhelmed the manual process.

The client required a scalable, automated solution to standardize invoice processing, ensure accuracy, and provide real-time visibility across accounts payable operations.
