PROJECT REQUIREMENTS

Back-End Invoice Data Validation for an Automated AP System

The client required a specialised provider for back-end invoice data validation to support their centralised, automated Accounts Payable (AP) system.

The client’s AP system received thousands of invoices monthly from various end users, each adhering to distinct data formats and submission protocols. Although the client’s proprietary AP platform automatically processed these bills, the inherent data variance caused it to generate a significant volume of exceptions. These exceptions were driven by issues like varying data formats, missing fields, and submission errors. Given that these invoice records directly impact financial transactions and adherence to trade regulations, these errors created a tangible risk of financial loss or legal exposure.

Therefore, the primary project requirements focused on:

  • Exception Handling: Manual review and correction for invoices that the AP system flagged as exceptions.
  • Data Integrity Check: Performing rigorous data validation by cross-checking the processed entries against the source documents to ensure accuracy across all differing languages and formats.
  • Regulatory Compliance: Guaranteeing secure data handling for all sensitive invoice information, meeting stringent international trade and data protection standards.
  • Capacity Assurance: Providing scalable operational coverage via rotational shifts across a six-day work week to effectively manage the high-volume, time-critical workflow.
PROJECT CHALLENGES

Handling Large Volumes of Inconsistent Invoice Data

The core difficulty lay in bridging the gap between the client's automated Accounts Payable (AP) system and the high volume of multi-format invoices it received, which frequently resulted in exceptions demanding manual intervention.

The key operational challenges we encountered were:

  • Inconsistent Data Structure: The high variability in invoice formats—different layouts, field placements, field names, and grouping of information— from various clients caused the AP system to frequently misinterpret entries and generate exceptions.
  • Invoice Quality Issues: Processing poor-quality and handwritten invoices proved difficult. Scans with low resolution, faded print, or unclear handwriting made it hard for the system to accurately capture essential details.
  • Language Variability & Complexity: Many invoices were not in English but in other regional languages and used local trade terms and abbreviations. The AP system struggled to interpret these correctly, assigning low confidence scores to these entries.
  • OCR Errors: Even minor OCR misreads in high-stakes data fields—like decimals, tax codes, or currency codes—introduced significant risks related to compliance and accurate financial reporting.
  • Scalability: Invoice submissions surged during typical business peaks, such as end-of-month and holiday cycles, causing exception volumes to spike significantly higher than the baseline.
  • Security Imperatives: Handling sensitive trade and financial invoice data necessitated adherence to strict compliance and security standards, even when distributed across the workforce.
OUR SOLUTION

A Robust and Scalable Invoice Validation Framework

To help the client manage their high-volume invoice load with precision and continuity, we implemented a scalable staffing and process model built around consistency, control, and flexibility. The framework included a dedicated team of five full-time resources for invoice processing, supported by four part-time resources activated during seasonal peaks. Operating in rotational shifts across six days a week, the team ensured uninterrupted processing and quick turnaround.

Our solution encompassed multiple operational layers to maintain data accuracy and performance:

1

End-to-End AP Exception Management

Every invoice flagged by the client’s AP system underwent a structured review and correction process guided by template-based SOPs. This ensured uniformity in handling diverse invoice formats and minimised workflow disruptions.

2

Manual Validation for Low-Quality or Handwritten Scanned Invoices

Invoices with poor scan quality or handwritten entries were verified manually. For high-risk fields, we adopted a double-key entry approach and escalated mismatches to senior reviewers for double accuracy assurance.

3

Multilingual and Domain-based Data Standardisation

Our team interpreted invoices containing regional languages and trade-specific terminology, translating and standardising them into English. Over time, we built a reference glossary of recurring terms to maintain long-term consistency and contextual accuracy.

4

Continuous Oversight by a Dedicated Project Manager

A project manager supervised both day and night shifts, overseeing workflows, conducting periodic QA checks, and ensuring each processed invoice record met the client’s quality benchmarks before submission.

5

Critical Field Verification and Compliance Checks

Key financial data, such as invoice totals, tax codes, and currency amounts, was cross-validated against client master data and reference databases to prevent compliance breaches or financial losses.

6

Flexible Scaling during Peak Periods

To accommodate volume surges during month-end closings or regional holidays, the framework allowed for rapid scale-up through overtime and additional part-time staffing, ensuring deadlines were consistently met without backlog accumulation.

7

Data Security & Compliance

All work was performed exclusively on the client-hosted AP system under ISO 27001-certified protocols. Security measures included strict NDAs, Role-Based Access Control (RBAC), secure VPN Access, a ‘No Local Storage’ policy, and compliance with ISO 27001:2022 standards.

Upholding Data Security in a Client-Hosted, Distributed Environment

Because the entire operation was managed within the client-hosted environment, establishing robust data security for sensitive business documents and maintaining confidentiality was paramount. We implemented a multi-layered security framework to meet this critical mandate:

Confidentiality Agreements

All team members signed Non-Disclosure Agreements (NDAs) to fully safeguard the client’s intellectual property.

Granular Access Management

We enforced strict Role-Based Access Control (RBAC) to limit system access to authorised associates as per their defined roles & responsibilities.

Encrypted Connection

Client system access was facilitated exclusively via secure, encrypted VPN servers.

Zero Local Data Retention

Any personal/financial client data could not be downloaded, copied, or saved on any local or external device.

Certified Data Security

All data handling followed ISO 27001:2022 and GDPR security requirements to ensure secure and compliant processing.

Project Outcomes

Our reliable, human-in-the-loop methodology and ability to adapt to global time zones led to immediate and sustained success. The collaboration resulted in a strategic, long-term three-year engagement.
