This case study supports From Spreadsheets to Systems: How HR Leaders Can Escape Broken, Disconnected Tooling and the audit method behind the fix in How to Audit Your HR Tech Stack for Manual Data Bridges.

Context

Sarah’s team ran onboarding the way most growing HR departments do: an ATS for candidates, an HRIS for employee records, and a spreadsheet-and-email process bridging the two. Every accepted offer meant manually re-typing the candidate’s information into the HRIS, forwarding paperwork by email, and tracking completion in a shared spreadsheet that only Sarah’s team knew how to read.

The team wasn’t understaffed. The process was the bottleneck. New hire data entry, form routing, and status tracking consumed hours every week that never showed up as a line item anywhere, because it was distributed across a dozen small manual tasks instead of one visible process.

Approach

Rather than replacing either the ATS or the HRIS, the fix was integration: connecting the two systems so an accepted offer automatically triggered the new hire record in the HRIS, routed the correct onboarding forms, and flagged missing signatures without anyone checking manually. The standardization step came first. Before building anything, the team documented exactly what happened at each stage of onboarding, since automating an undocumented process would have just made existing inconsistencies move faster.

Once the process was written down and agreed on, an integration platform handled the data handoff between systems, matching the automation level to what the process actually needed: an in-product workflow for standard approvals, and a connected data sync for everything crossing between the ATS and HRIS.

Implementation

The build focused on the single highest-friction handoff first: candidate data flowing from the ATS into the HRIS the moment an offer was accepted. That one connection eliminated the most repetitive re-entry work in the entire process. From there, automated form routing and a status tracker replaced the shared spreadsheet, giving the team a live view of who was missing what, instead of a static file someone had to update by hand.

The new system ran alongside the old spreadsheet process for one full onboarding cycle before the spreadsheet was retired, confirming the automation caught everything the manual process used to catch.

Results

Sarah’s team reclaimed 12 hours a week that had been absorbed by manual re-entry, form chasing, and status tracking. Hiring time, from offer acceptance to a fully onboarded employee, dropped 60%. Neither number came from working faster. Both came from removing steps that never needed a human in the first place.

Lessons Learned

The biggest lesson wasn’t technical. It was that the team had assumed a bigger project, a full HRIS replacement, was the only way to fix the problem. The actual fix was narrower: one well-built integration and a standardized process behind it. Teams chasing a full replatform routinely overlook the smaller, faster win sitting between two systems they already own.
