Reimbursable Expenses Are the Real Procurement Problem for Architects

Most commercial architecture contracts include a line for reimbursable expenses, large-format printing, physical models, renderings, mileage for site visits, that the client agrees to pay on top of the design fee. Those costs are usually small individually and easy to lose track of collectively, which is exactly the problem: a firm that under-captures reimbursables across a busy quarter is quietly absorbing costs the client contract says they shouldn't have to.

Software licensing, particularly BIM tools that scale with active headcount on a project, is the other recurring cost worth getting right. Airbase and Procurify approach both differently enough to matter.

Why Reimbursables Get Lost Between the Print Shop and the Invoice

A project architect sends a large-format print job to an outside print shop on a Friday afternoon to have plans ready for a Monday client meeting. The invoice arrives two weeks later, gets coded to a general printing expense account by whoever processes accounts payable, and by the time the project's monthly invoice goes out, nobody remembers to check whether that specific print run was billed back to the client. Multiply that by every renderer, model shop and courier a firm uses across a dozen active projects, and the leakage adds up to a meaningful percentage of what the firm was contractually entitled to recover.

Airbase for Fast, Small Reimbursable Purchases

Print shops, model makers, courier services, these are exactly the kind of small, frequent, project-tied purchases that benefit from card-first speed: a project architect needs the print job today, not after a multi-step approval. Airbase's custom fields let that architect tag the project and mark the cost as reimbursable at the point of purchase, which is the only reliable way to make sure it shows up correctly on the next client invoice instead of getting buried in general overhead.

Procurify for BIM Software Seats That Track Project Staffing

BIM software licenses, whether seat-based or usage-based, tend to track closely with how many people are actively working a project at a given phase, similar to the pattern in other project-based design and engineering firms. Procurify's request-first flow works well here because a studio lead names the project and expected seat count before licenses are provisioned, which makes it natural to also set a review point for when that phase ends and seats should scale back down.

A Worked Example: Closing Out the Reimbursable Gap on One Project

Say a mid-size commercial project runs eight months from schematic design through construction documents, generating a steady stream of print runs, a physical model for a client presentation, and two rounds of renderings for a planning commission hearing. If each of those purchases is tagged to the project and marked reimbursable at the point of purchase, the project's monthly invoice can include an accurate reimbursable line without anyone reconstructing receipts at month end. If they're not tagged consistently, the firm typically finds, when someone finally audits it at project close, that reimbursable capture ran well under what the contract entitled them to bill, a gap that's much harder to recover after the fact than to prevent from the start.

A Common Mistake: Treating All Printing as Overhead

Some firms default to coding all print shop and model maker invoices to a general "printing and reproduction" overhead account, on the theory that sorting reimbursable from non-reimbursable print jobs is more trouble than it's worth. That default quietly shifts real, contractually recoverable client costs onto the firm's own books. A short rule, printing tied to an active client deliverable is reimbursable and gets tagged to the project; internal marketing or proposal printing is overhead, removes most of the ambiguity without requiring a judgment call on every single print job.

A simple routine for capturing reimbursables:

  1. Tag each print, model or courier purchase to its project, and mark it reimbursable at the point of purchase.
  2. Code print shop and model maker invoices by whether they tie to an active client engagement, instead of defaulting everything to overhead.
  3. Log site visit mileage and travel against the project when it happens, not at month end.
  4. Compare the reimbursable line on recent client invoices with print, model and courier spend for the same projects to find leakage.

Coordinating Reimbursables Across Consultants on the Same Project

A commercial project usually involves the architect plus structural, MEP and civil consultants, each potentially generating their own reimbursable costs that flow through the architect's invoice to the client as the prime consultant. That adds a layer the reimbursable tracking has to handle: a consultant's print or travel cost needs to be captured and passed through accurately, not absorbed by the architecture firm because nobody built a clean handoff for consultant-generated reimbursables.

The firms that handle this well set up a standard monthly reimbursable submission from each consultant, due before the architect's own invoice is finalized, and tag those costs to the project the same way they'd tag their own print shop invoice. Skipping that step is a common reason architecture firms find themselves eating a consultant's reimbursable cost that should have been passed through to the client.

Executive Capability Standard

What Good Looks Like

A well-run architecture firm can show, for any active project, exactly what reimbursable costs have accrued and whether they've been billed to the client, without a project accountant reconstructing receipts from memory at invoice time.

Building The Capability (5-Stage Skill Ladder)

1. Learn:Pull the reimbursable line from your last three client invoices and compare it against total print, model and courier spend for the same projects to check for a gap.
2. Do Manually:Require project architects to tag every print shop, model maker and courier purchase as reimbursable or overhead at the point of purchase, in a shared tracker if needed.
3. Delegate:Assign a project accountant or office manager to review the tagged reimbursable log weekly and flag anything missing a project or reimbursable status.
4. Automate:Connect Airbase or Procurify's project tagging fields to your billing system so reimbursable costs flow directly into the next client invoice without manual re-entry.
5. Buy:Move to a platform that reconciles reimbursable spend against each project's contract terms automatically and flags gaps before the invoice goes out.

Frequently Asked Questions

How do we handle a rendering used for both a client presentation and the firm's own portfolio?

Bill the client for the portion of the cost tied to their specific deliverable, and treat any additional cost incurred purely for the firm's own marketing use as overhead. If the rendering was produced specifically for the client meeting and the firm is simply reusing the same file later for its portfolio, the full cost is still reimbursable.

What's the fastest way to check if we're under-capturing reimbursables?

Compare the reimbursable line on your last few client invoices against your total print shop, model maker and courier spend for the same projects over the same period. If the gap is large, purchases are landing in general overhead instead of being tagged and billed back, which points to a tagging discipline problem rather than a platform problem.

Should site visit mileage go through the same system as vendor invoices?

Yes, treat site visit mileage like any other reimbursable cost and log it against the project when the trip happens. Reconstructing it from a calendar at month end invites missed charges. Both platforms support mileage or travel expense entries tagged to a project the same way they support vendor invoices.
