How do I set up expense approval routing for a construction company?

Key takeaways

• Vergo routes approvals by GL account, by amount, or by project—fitting how construction companies already control spend—and syncs approved expenses to your ERP with job cost mapping intact.
• Route expenses to the project manager responsible for the job number, not to a central inbox, to keep cost accountability with budget owners.
• Set dollar thresholds that match your project size—common tiers are under $250 to supervisor, $250–$2,500 to project manager, and above $2,500 to controller or CFO.
• Require valid job numbers and cost codes before the approval workflow initiates to prevent unapproved expenses from reaching accounting without proper allocation.
• Build escalation rules with named backup approvers for project managers who are frequently on-site, triggering after 48–72 hours of inactivity.
• Audit routing quarterly as job rosters change and project managers turn over to avoid rules pointing to former employees.

Why Expense Approval Routing Breaks Down in Construction

Construction companies operate across multiple job sites, cost centers, and crews simultaneously. Without a defined approval chain, expenses get submitted to the wrong person, sit unapproved for weeks, or get coded to the wrong job number—causing budget overruns that only surface at month-end. The core problem is that most construction firms treat expense approval as a one-size-fits-all process. A $40 hardware store receipt and a $4,000 equipment rental don't belong in the same workflow. Common breakdown points include no role clarity at the field level, where foremen submit expenses directly to the CFO and bypass project managers who own the job budget; missing cost code assignment, creating manual rework for accounting; threshold blind spots where approvers approve everything regardless of amount; and no escalation path when a primary approver is unavailable in the field.

The Recommended Expense Approval Workflow

This process applies to any construction company with field crews, project managers, and a central accounting function. First, define expense categories—materials, fuel, tools, meals, lodging, subcontractor reimbursements—and require a job number and cost code at submission for every category. Second, set dollar thresholds for each approval tier: a common model routes under $250 to the direct supervisor or foreman, $250–$2,500 to the project manager, and above $2,500 to the controller or CFO. Third, assign the first-level approver by job or crew, routing field expenses to the project manager responsible for that job number. Fourth, require cost code validation before approval is triggered so the workflow only initiates after the submitter has assigned a valid job number and cost code. Fifth, build in an escalation rule for delayed approvals—if an expense sits unapproved for 48–72 hours, automatically escalate to the next level and name a specific backup approver for each primary. Vergo routes approvals by GL account, by amount, or by project, and approval workflows are optional—you can skip them entirely and let policy flags catch only what breaks a rule.

A Practical Example

A general contractor runs six active projects ranging from $500K to $3M. Each project manager owns the budget for their job. When a foreman on the $3M commercial build purchases $180 in materials from a local supplier, the expense routes directly to that project's manager because it falls under the $250 threshold and carries the correct job number. When the same foreman rents a skid steer for $1,800, the expense routes to the project manager but also requires a photo receipt because it exceeds the $75 documentation threshold. If the project manager doesn't approve within 72 hours—common when they're on-site all day—the system escalates to the operations director who serves as the designated backup. Once approved, the expense syncs to the ERP with the job number and cost code intact, posting directly to the WIP schedule without manual re-entry by the accounting team.

Tips for Construction Controllers Setting Up Approval Routing

Tie approval authority to job ownership, not org chart position alone. A project manager overseeing a $2M job should have appropriate approval authority for expenses tied to that job, even if their title is junior. Separate approval routing for union versus non-union labor reimbursements, as these often have different documentation requirements and audit trails under collective bargaining agreements. Document your threshold policy in writing—controllers frequently enforce undocumented approval rules, and when auditors or bonding companies review expense processes, written policy protects you. Audit the routing quarterly, as job rosters change, project managers turn over, and new cost codes get added. A routing rule pointing to a former employee creates silent failures that stall approvals and frustrate field teams.

How Vergo Handles This

Vergo routes approvals by GL account, by amount, or by project, fitting how construction companies already control spend. Approval workflows are optional—you can skip them entirely and let policy flags catch only what breaks a rule. Transactions are ready to code the moment they happen, with no waiting for clearing, and once they clear they sync into your accounting or ERP software with job cost mapping intact. Vergo integrates with every ERP and accounting software, so approved expenses land in the right job cost buckets automatically. Employees handle everything by text message—no app to download, no portal login—and Vergo chases missing receipts itself instead of waiting for a report. Card spend, employee reimbursements, and AP invoices run through one coding model with the same coding, same review, and one reconciliation. Connecting your existing cards involves no card applications, no re-issuing, and no banking change. See how it works at getvergo.com/products/expense-management.
