How do architecture firms handle reimbursements?

Key takeaways

• Reimbursable expenses in architecture firms are project costs incurred on behalf of clients and recovered through contractual billing, typically defined in AIA B101 agreements.
• Effective reimbursement handling requires linking every expense to a project and phase at the point of capture, applying the correct markup, and providing documentation for client billing.
• Vergo proposes coding by inference from your own accounting structure and history, so reimbursables are tied to the correct project and phase the moment they happen—no rule library to build, and new vendors are coded on first sight.
• Missed reimbursables represent lost revenue—a single forgotten consultant invoice or site visit expense can cost thousands in unbilled charges.
• Architecture firms need systems that align expense capture with project phases and billing cycles to ensure all reimbursable costs are recovered.

What are reimbursable expenses in architecture firms?

In architecture, reimbursable expenses are project costs that a firm incurs on behalf of a client and is contractually entitled to recover. These are distinct from the firm's professional fees. Common examples include reproduction and printing costs, travel and lodging for site visits, permit and filing fees, third-party consultant fees (such as structural or MEP engineers), and model-making or rendering services.

The governing document is typically the AIA B101 owner-architect agreement, which includes a dedicated article defining what qualifies as a reimbursable expense and the markup rate the firm may apply—commonly 10% above actual cost. Some contracts cap reimbursables or require prior client approval for expenses above a threshold. Reimbursables are not a minor line item. On large projects, they can represent 5–15% of total project billings. Mismanaging them means either leaving revenue on the table or triggering billing disputes with clients.

Why reimbursement tracking matters in architecture firms

Architecture firms operate at the intersection of professional services and construction, which creates accounting complexity that generic expense management tools are not designed to handle. The reimbursement process must align with project phases—schematic design, design development, construction documents, construction administration—because many contracts limit reimbursables to specific phases.

For a controller at an architecture firm, this creates several practical challenges: phase-level cost allocation requires coding an employee's site visit travel to the correct project phase, not just the project. Consultant pass-through tracking demands capturing sub-consultant invoices, applying the contracted markup, and billing them to the client on the appropriate cycle. Receipt documentation is increasingly required by clients for backup, especially on public or institutional projects. Markup enforcement prevents staff from submitting expenses that get billed at cost or overlooked entirely. Billing cutoff alignment ensures reimbursables don't slip to the next cycle or get forgotten. When reimbursements are tracked informally—through email, shared spreadsheets, or generic expense tools—firms routinely miss billable items.

A practical example: tracking site visit reimbursements

A project architect travels to a job site for a construction administration meeting and submits a mileage reimbursement. In an informal process, that expense is reimbursed to the employee through the HR system but never linked to the project. At invoice time, the project manager doesn't know it was incurred, and the client is never billed. The firm absorbs the cost.

In a structured process, the same expense is submitted through a project-linked workflow. The employee selects the project number and phase code at submission. The controller sees the expense in a pending reimbursables queue, confirms it meets the AIA B101 reimbursable definition, applies the 10% markup, and includes it on the next client invoice with the receipt attached as backup. Vergo handles this by coding reimbursements to project and phase at the moment they happen, ensuring the firm recovers the cost and maintains proper documentation for client review.

Handling sub-consultant pass-through costs

Sub-consultant invoices represent a significant category of reimbursable expenses in architecture. A structural engineering firm invoices the architect $18,000 for design services. Under the owner-architect agreement, this is a reimbursable at cost plus 10%. The accounts payable team must flag this invoice as a pass-through, tie it to the correct project and phase, and ensure the $19,800 billable amount appears on the next client draw.

Without a system to track these invoices as reimbursables at the point of entry, they often get coded as regular firm expenses or sit in accounts payable without being linked to a project. This results in the firm paying the consultant but never recovering the cost from the client. On a project with multiple consultants—structural, MEP, geotechnical, landscape—the cumulative unbilled amount can represent tens of thousands in lost revenue.

How Vergo handles this

Vergo is an AI-native, card-agnostic expense management platform that handles architecture firm reimbursements by coding every transaction to project and phase at the moment it happens. 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. 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.

Vergo proposes the coding by inference from your own accounting structure and history—no rule library to build, no keyword lists to maintain, and new vendors are coded on first sight. Every coding shows why it was chosen, so a reviewer confirms in seconds instead of re-coding by hand. 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.

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. Connecting your existing cards involves no card applications, no re-issuing and no banking change. Vergo integrates with every ERP and accounting software, ensuring reimbursables flow directly into project billing without manual re-entry.
