Context

A leader in entertainment payroll processed enormous volumes of timecards, often in inconsistent and handwritten formats, largely by hand — slow and error-prone.

The challenge

Timecards vary wildly in format and quality. Extracting accurate data from them at scale meant combining reliable OCR with AI that could interpret messy, inconsistent documents and flag what it wasn't sure about.

Our approach

Read any timecard

We built an OCR layer to digitize timecards across formats, including difficult and handwritten ones.

Interpret with AI

AI extracts and structures the relevant fields, interpreting inconsistent layouts rather than relying on rigid templates.

Validate and escalate

Automated validation catches errors, and a human-in-the-loop step handles the exceptions the system flags as uncertain — accuracy without full manual review.

Architecture

Document AI for genuinely varied input formats

Entertainment-industry timecards come in a wide range of formats — different productions, different unions, different paper and digital templates — and the starting point was stacks of these in formats that varied enough that a single rigid template-matching approach wouldn't hold up. The document-AI extraction layer is built to handle this variation: it identifies the relevant fields (worker identity, hours, rates, job codes, date ranges) across different layouts rather than requiring each format to be pre-registered as a known template, using a combination of layout analysis and field-level extraction models.

Validation against payroll business rules, not just extraction

Extracted data isn't automatically correct — a misread digit, a field extracted from the wrong location on an unusual layout, or a timecard that's internally inconsistent (hours that don't sum correctly, a date outside the expected pay period) all need to be caught before the data reaches payroll. The validation layer applies business rules specific to entertainment payroll (union rate rules, overtime calculations, job-code validity) and flags discrepancies for human review rather than passing everything through silently — the goal was to catch errors before they became payroll mistakes, not to eliminate human review entirely.

Normalisation into a standard schema for payroll export

Once extracted and validated, data from wildly different source formats is normalised into a standard schema that the payroll system can consume directly. This is where the 'stacks of varied-format timecards become clean payroll data' transformation actually happens — the payroll system doesn't need to know or care what the original timecard looked like, because by the time data reaches it, every record has the same shape.

What we built

  • A document-AI extraction pipeline handling varied timecard formats
  • Field-level extraction for worker, hours, rate, and job-code data
  • A validation layer applying entertainment-payroll business rules
  • Discrepancy flagging for human review
  • A normalisation layer producing standard payroll-ready output

Results & impact

Timecard processing became faster and more accurate, with manual effort focused only on genuine exceptions — freeing the payroll team from rote data entry.

  • The entertainment payroll leader replaced manual data entry from varied-format timecards with an automated extraction-and-validation pipeline.
  • Validation against payroll business rules caught discrepancies — miscalculated hours, rate mismatches — before they reached payroll processing, where errors are far more costly to fix.
  • The normalisation layer meant the payroll system received consistent input regardless of the source timecard's original format, simplifying downstream processing.
  • As a scoped GenAI/document-AI project, the pipeline was delivered against a defined set of timecard formats with a clear validation rule set — a bounded, well-specified deliverable rather than an open-ended 'automate payroll' initiative.
