How do I manage per diem reimbursements for construction crews on travel jobs?

Key takeaways

• Vergo automates per diem submission through text messages that require no app download, proposes job cost coding by inference from your accounting structure, and syncs approved transactions directly to your construction ERP.
• Per diem reimbursements require clear policies that specify rates, eligible expenses, and approval thresholds for each job site or region.
• Field crews should submit per diem requests with job codes and supporting documentation through accessible tools that work in the field.
• Approval workflows should route requests to supervisors based on project, cost code, or dollar amount to maintain budget control.
• Approved reimbursements must sync directly to your construction ERP with proper job cost coding to avoid manual re-entry and reconciliation errors.
• Real-time visibility into request status reduces crew frustration and improves communication between field and accounting teams.

What makes per diem reimbursements challenging in construction?

Per diem reimbursements in construction face unique complications because policies vary by project location, union agreements, and prevailing wage requirements. A crew traveling to a high-cost urban project may receive different daily rates than one working in a rural area, and tracking these variations manually creates compliance risk. Field crews often lack reliable internet access to submit requests through traditional portals, leading to paper receipts that accumulate for weeks before reaching accounting. Vergo solves this with text-based submission that works from any phone without app downloads or portal logins, letting crews submit per diem details and receipts immediately from the field. The handoff between field supervisors who approve per diems, accounting staff who code them to job cost, and payroll teams who process payments introduces multiple opportunities for error. Delayed reimbursements damage crew morale and retention, while incorrect job cost allocation distorts project profitability reporting and makes it difficult to forecast labor costs accurately on future bids.

How to establish an effective per diem policy

An effective per diem policy begins with clear rate schedules tied to geographic regions or specific project assignments, documented in language accessible to field crews. Specify which expenses qualify as per diem versus itemized reimbursements—typically lodging, meals, and incidentals when crews are more than 50 miles from their tax home. Set approval thresholds that empower field supervisors to authorize routine requests up to a dollar limit while routing larger or unusual claims to project managers or controllers. Include the job cost structure in the policy so crews understand which cost codes apply to their per diem expenses, reducing back-and-forth corrections. Build in compliance with IRS per diem rates and prevailing wage rules for public works projects where applicable. Review the policy annually or when opening projects in new regions, and communicate changes through toolbox talks and written updates rather than assuming crews will read policy manuals on their own.

A practical example

A mechanical contractor sends a five-person crew to install HVAC systems on a hospital project 200 miles from the home office. The project spans three months, and the policy allows $75 per day for meals and incidentals plus actual lodging receipts up to $120 per night. Each crew member submits per diem requests weekly, specifying the hospital project number and the labor cost code for their trade. The foreman approves requests under $1,000 for the week; anything higher routes to the project manager. Approved per diems code automatically to the hospital job with the correct cost code and sync to the construction ERP, where they appear on the job cost report alongside material and equipment expenses. Payroll receives the approved amounts and includes them in the next pay cycle, typically within five business days of approval. This cycle repeats weekly until the crew demobilizes, with all per diem expenses properly allocated to the hospital project for accurate profitability tracking and client billing if the contract allows reimbursable per diems.

Integrating per diem data with your construction ERP

Integration between per diem management and your construction ERP eliminates double entry and ensures job cost accuracy. Approved per diem reimbursements should flow directly into the general ledger with the correct project number, cost code, and cost type—typically coded as labor burden or reimbursable expenses depending on your chart of accounts. The integration must also feed payroll systems so crews receive payment without manual data transfer that introduces errors and delays. Real-time synchronization allows project managers to see per diem expenses on job cost reports immediately after approval, giving them current budget status rather than waiting for month-end close. The integration should handle split coding when a crew member works on multiple projects during a single pay period, allocating per diem proportionally. Reporting becomes more powerful when per diem data sits alongside other job costs, enabling analysis of total crew costs by project phase or comparison of actual travel expenses against bid assumptions.

How Vergo handles this

Vergo manages per diem reimbursements for construction crews through text-based submission that requires no app download or portal login—field employees text their per diem details and receipts from any phone. Vergo proposes job cost coding by inference from your accounting structure and history, suggesting the correct project number and cost code based on the crew member's assignment, with every coding showing why it was chosen so reviewers confirm in seconds. Approval workflows route requests by project, GL account, or dollar amount to match your existing spend control structure, or you can skip approval flows entirely and let policy flags catch only what breaks a rule. Transactions sync into your construction ERP the moment they clear, carrying the approved job cost coding through to the general ledger and payroll without re-entry. Card spend, employee reimbursements, and AP invoices run through one coding model—same coding, same review, one reconciliation—so per diems reconcile alongside other project expenses. Vergo integrates with every ERP and accounting software used in construction.
