What should a construction company include in its expense reimbursement policy?
A construction company's expense reimbursement policy should define eligible expense categories (mileage, lodging, meals, tools, materials), spending limits, required documentation, job cost coding rules, approval workflows, reimbursement timing, and non-reimbursable items. Vergo enforces policy rules automatically by routing expenses through project-based approval workflows and requiring job codes at the point of capture.
Key takeaways
- An expense reimbursement policy establishes what expenses are reimbursable, spending limits, required documentation, and how expenses must be coded to projects.
- Construction policies must address field-specific categories like mileage between job sites, per diem for remote work, emergency tool purchases, and equipment rentals.
- Every reimbursable expense should be assigned to a project number and cost code at submission to keep job budgets accurate in real time.
- Policies should specify approval workflows, documentation windows, reimbursement timing, and explicitly list non-reimbursable items.
- Vergo enforces policy rules automatically through project-based workflows and real-time coding, with approval workflows that route by GL account, amount, or project and employees handling everything by text message.
What an expense reimbursement policy covers
An expense reimbursement policy is a written document that establishes the rules governing how employees submit, approve, and receive payment for out-of-pocket business costs. At its core, the policy answers three questions: what is reimbursable, how much the company will pay, and what proof is required. In construction, this document must address field operations that create expense categories office-based businesses rarely encounter—fuel and mileage for crews moving between job sites, tools and consumables purchased on-site for emergencies, per diem rates for workers on remote projects, equipment rental deposits, and subcontractor meals during extended shifts. A policy that does not name these categories explicitly will produce inconsistent practices as supervisors make individual judgment calls on every submission. Effective policies also connect reimbursement directly to the job cost structure, with every expense assigned to a project number and cost code at the time of submission.
Why construction companies need a formal reimbursement policy
Without a formal policy, reimbursement becomes a negotiation. One foreman gets approved for a $75 site lunch; another gets denied for $40 of fasteners purchased to keep work moving. This inconsistency creates employee dissatisfaction, inflates overhead accounts with costs that should hit job cost, and complicates audits and certified payroll reviews on public projects. For a controller, the absence of a policy creates downstream accounting problems: expenses submitted without job numbers require manual reclassification, receipts submitted weeks late distort WIP schedules, and reimbursements paid without proper documentation create exposure during IRS audits or bonding reviews. For a project manager, unclear policy means the project budget does not reflect true cost, as crew expenses reimbursed through payroll adjustments or petty cash often never reach the job cost ledger at all.
Core elements to include in the policy
Every construction expense reimbursement policy should include eligible expense categories (mileage, fuel, lodging, meals, tools, materials, subcontractor-related costs), spending limits and caps (per diem rates, hotel nightly maximums, meal limits by meal type), and documentation requirements (itemized receipts, acceptable formats, submission window such as within five business days). Job cost coding instructions must require a project number and cost code on every submission. The policy should define the approval workflow—who approves field expenses, who approves exceptions, and escalation thresholds—along with reimbursement timing (payment cycle and method). It must explicitly list non-reimbursable items such as alcohol, fines, personal purchases, and expenses without receipts. For companies using corporate cards, the policy should explain how card expenses are reconciled and who reviews statements.
A practical example
Before implementing a formal policy, a superintendent on a three-week bridge project purchases hotel stays, fuel, and meals on a personal card and submits a handwritten list at month-end. Accounting has no job number, no receipts, and no way to verify amounts. The $4,200 reimbursement hits general overhead, and the project's actual cost is understated on the WIP schedule. After implementing a policy, the same superintendent uses a company-issued card governed by rules that specify a $175-per-night hotel cap, IRS-rate mileage reimbursement, and a $60-per-day per diem for meals. Each transaction requires a digital receipt and a project number entered within 48 hours. The $4,200 flows directly to the bridge project under cost codes 01-500 (travel) and 01-510 (meals), and the WIP schedule reflects actual field cost. A policy that defines a dollar threshold—items under $150 may be reimbursed as direct field expense; items $150 and above require a purchase order—eliminates the grey zone where crew members buy small tools and supervisors argue about project versus shop assignment.
How Vergo handles this
Vergo enforces expense reimbursement policy automatically through project-based workflows and real-time coding. Approval workflows are optional and fit how you already control spend: route by GL account, by amount, or by project—or skip approval flows entirely and let policy flags catch only what breaks a rule. Employees handle everything by text message—no app to download, no portal login—and Vergo chases missing receipts itself. Vergo proposes the coding by inference from your own accounting structure and history, so new vendors are coded on first sight without keyword lists to maintain, and every coding shows why it was chosen so a reviewer confirms in seconds. Transactions are ready to code the moment they happen—no waiting for clearing—and once they clear, they sync into your accounting or ERP software. Card spend, employee reimbursements, and AP invoices run through one coding model—same coding, same review, one reconciliation—and payment stays on the rails you already use. Vergo integrates with every ERP and accounting software.

Frequently Asked Questions
Should a construction expense policy set different rules for field employees vs. office staff?
Yes. Field employees incur categories—site fuel, per diem on remote projects, emergency material purchases—that office staff rarely encounter. A single undifferentiated policy either over-restricts field crews or opens reimbursement to categories that don't apply in the office. Most construction policies define employee tiers with category-specific rules for each.
What is a reasonable per diem rate for construction workers on remote projects?
Most construction companies anchor per diem to IRS-published federal per diem rates, which vary by location. For 2024, the standard lodging rate is $107/night and meals and incidentals are $59/day, but high-cost project locations carry higher rates. Companies working on prevailing wage projects must also verify whether per diem affects fringe benefit calculations.
How should reimbursed expenses be coded to avoid distorting job cost reports?
Every reimbursed expense should carry a project number and a cost code at submission—not after accounting reviews it. Common cost codes used in construction include travel (01-500), meals (01-510), and field supplies (01-520). Coding at source prevents expenses from landing in overhead and keeps WIP schedules accurate throughout the project lifecycle.
How often should a construction company update its expense reimbursement policy?
At minimum, annually—and whenever IRS mileage or per diem rates change, when the company takes on new project types (e.g., Davis-Bacon prevailing wage work), or after an audit identifies classification errors. Policies tied to fixed dollar thresholds should also be reviewed as material and fuel costs shift with market conditions.
What documentation is legally sufficient to support an expense reimbursement?
The IRS requires that reimbursements under an accountable plan be supported by receipts showing amount, date, vendor, and business purpose. For construction, business purpose should include the project name or number. Digital photos of itemized receipts are accepted. Credit card statements alone are not sufficient because they don't itemize individual purchases.
Can construction expense management software enforce policy rules automatically?
Yes. Platforms like Vergo embed policy rules—spending caps, required cost code fields, receipt attachment requirements, approval routing thresholds—directly into the submission workflow. This catches policy violations before they reach accounting rather than during month-end review, reducing reclassification work and improving job cost accuracy across active projects.
