Foundation payroll to BambooHR: PDF-first integration
If your construction company runs payroll in FOUNDATION® but manages HR in BambooHR, you can still automate the pay-stub handoff, even without an API. The practical path is PDF-first: export the payroll packet, split it into per-employee stubs, validate totals against a CSV (when available), and upload the right PDF into each employee’s BambooHR file area.

The problem: pay stubs are trapped in a single payroll PDF

After each payroll run, FOUNDATION typically produces a bulk payroll packet (often a single PDF with every employee’s stub). HR then has to:
  • split the file into individual pay stubs
  • name each PDF correctly
  • upload each stub to the right employee record
  • answer follow-up questions when the stub detail is too compressed
The manual process is slow, and the risk is real: one wrong split or mis-upload can put the wrong employee’s pay stub in the wrong profile.

What “PDF-first” means (and why it’s often the best option)

A PDF-first integration doesn’t try to force a real-time sync between systems. Instead, it builds a reliable automation around the artifact that payroll already produces: the pay-stub PDF.
This approach makes sense when:
  • there is no Foundation API available for payroll exports
  • the business cares about preserving the detailed pay-stub format employees already understand
  • you still want the HR team to manage distribution and retrieval in BambooHR

The PDF-first integration workflow (Foundation → BambooHR)

Here’s the end-to-end workflow that works well in practice.

1) Export the payroll packet (PDF) after each run

Trigger the process right after payroll is finalized.
Common ways to trigger:
  • a controlled “drop zone” folder where the PDF is uploaded after each payroll run
  • an SFTP location where exports land automatically
The goal is to make the export step predictable and auditable.

2) Confirm whether the PDF is real text or image-based

This is the first technical fork.
  • Text-based PDF: splitting + extraction is straightforward and reliable.
  • Image/scanned PDF: you likely need OCR, which adds cost and accuracy risk.
If the export isn’t text-based, you can still automate, but you should expect more exception handling.

3) Split the PDF into per-employee stubs (with hard safety checks)

A safe splitter should do more than “page ranges.” It should:
  • detect employee identifiers (name + employee ID, when present)
  • prevent duplicate matches
  • prevent cross-employee page leakage
  • route any ambiguous pages into a review bucket
This is where most payroll risk lives, so it’s worth building the checks.

4) Validate totals with a CSV (when possible)

Even when the employee-facing document is the PDF, a CSV export can act as a backend validation layer.
Use it to check:
  • gross pay totals per employee
  • hours totals (regular/OT)
  • fringe or job breakdown totals (where applicable)
If the CSV is summarized (a common issue), you can still validate at the “headline” level (gross/net) and use the PDF for the full breakdown.

5) Upload pay stubs into BambooHR (employee Files)

Once each stub is generated, upload it to the correct employee record in BambooHR.
Key implementation details:
  • choose a stable matching key (BambooHR employee ID is best; email is a fallback)
  • enforce naming conventions, e.g. Pay Stub - 2026-06-04 - Lastname, Firstname.pdf
  • store stubs in a consistent location so employees can self-serve

6) Exception handling (required for payroll)

Build a short list of non-negotiable controls:
  • Unmatched employee bucket: any stub that can’t be mapped automatically gets quarantined
  • Upload audit log: every stub upload is logged (employee, pay period, file hash)
  • Immutable archive: the original export packet is stored securely for audits

Expected timeline and costs (ballpark)

Every implementation varies, but PDF-first payroll automations typically break into:
  • initial build and QA (often a few weeks, depending on export consistency)
  • ongoing per-payroll processing (automated run + exception handling)
  • a small monthly maintenance plan (monitoring, fixes when payroll formats change)

Risks and mitigations

  • Risk: wrong pay stub in the wrong profile → mitigate with strict matching rules + quarantine bucket.
  • Risk: PDF format changes → mitigate with monitoring + test runs before each deployment.
  • Risk: scanned PDFs → mitigate by pushing for a text export or budgeting for OCR and manual reviews.

When to consider a non-PDF integration

If Foundation can export a consistently detailed CSV (or provide a supported integration method), you can shift to a “data-first” workflow and generate pay stubs from structured data. But in many construction payroll environments, PDF-first is the fastest path to a dependable result.
