Digital audit transformation: Collecting and ingesting data

By: Wolters Kluwer Tax and Accounting

If you've been in the audit game for more than five minutes, you know the drill. Client sends over a USB drive with all sorts of Excel files, many of which don’t match the chart of accounts they gave you last month. Half the data is in PDFs. Others are in some proprietary system format that doesn’t convert easily.

Without the right tools, this can lead to days or weeks of manual sorting, classification, and follow-up before substantive work can even begin.

The data collection nightmare

Junior staff would spend weeks manually sorting through files, trying to figure out which expenses belonged in which buckets. Account groupings were more art than science, and inevitably, someone would discover a big batch of data right before the fieldwork deadline.

Then came the quality control headaches.

  • How do you know if the numbers actually tie out?
  • Is that $50,000 variance a real issue or just a mapping problem?

And then there’s missing documentation. Chasing clients for missing documentation adds to the time pressure, especially when the required reports are buried in different systems.

AI-enabled data collection

Instead of drowning in data chaos, you can now automate the entire collection and preparation process, with AI-enabled data collection tools that give auditors cleaner data faster and reduce the risk of errors.

No more manual account grouping

AI can automatically classify accounts based on your firm’s established preferences and prior-year mappings, applying these rules consistently across engagements. This includes creating standardized tax groupings that align with your tax preparation requirements.

Once groupings are complete, the system can export directly into your tax software, eliminating duplicate entry and ensuring consistency between the audit and tax processes.

Multi-format data ingestion

AI-enabled ingestion tools can accept structured data from ERP systems, unstructured spreadsheet files, and exports from multiple platforms. The technology standardizes this information into a single, workable format, ready for review and analysis.

Automated validation

AI-driven validation checks catch problems before they become problems. The system can spot inconsistencies, flag missing elements, and identify data that looks suspicious. Addressing these issues before fieldwork begins ensures a smoother audit process.

Pre-processing for analytics

The real magic happens in the pre-processing phase. Instead of discovering data problems during fieldwork, AI can identify and flag issues before you even start testing. The system will highlight problems and anomalies so you can do your work with confidence.

This allows for preliminary risk assessments, identification of unusual trends, and more precise planning before substantive testing starts. 

Direct system integration

You can also deploy direct integration with client systems through secure APIs and open banking connections. Instead of relying on whatever export the client remembered to send you, you can pull financial data directly from the source.

It's real-time, it's accurate, and it eliminates the telephone game that happens when data passes through multiple hands.
