What is the best expense management software for engineering firms using Deltek Vision?

Deltek Vision's project-phase-task hierarchy is exactly how Vergo codes transactions as they happen. Employees submit receipts by text, coding is inferred from your Vision structure, and expenses sync directly into Vision without file imports or re-entry — an AI-native platform for engineering firms.

Key takeaways

  • Engineering firms on Deltek Vision need expense management that codes to the project-phase-task hierarchy at the point of capture, not weeks later during cleanup.
  • Vergo proposes coding by inference from your Vision accounting structure and history, with no rule library to build and no keyword lists to maintain, so new vendors are coded on first sight.
  • The right tool eliminates re-entry, codes at every WBS level, and syncs coded transactions directly into Vision without file imports.
  • Field engineers should submit receipts in seconds without logging into desktop interfaces, and reimbursable expenses must be marked for client billing as they occur.
  • Complete audit trails linking receipts, GL accounts, project coding and approvals are essential for government contract audits and earned-value reporting.

Why engineering firms on Deltek Vision need dedicated expense management

Deltek Vision handles project accounting well, but its native expense entry is clunky for staff away from the office. Engineers traveling to client sites, attending design reviews or buying testing supplies shouldn't need to log into Vision's desktop interface to submit a receipt. The result is predictable: late submissions, miscoded expenses, and accounting chasing project charges at month-end. Common problems include expenses on the wrong project-phase-task combination that distort project cost reports, per diem and mileage entries submitted weeks late that skew profitability, staff re-entering expense data from spreadsheets into Vision, no timely view of reimbursable expenses that should be billed to clients, and audit trails that fail to connect receipt images to the Vision transaction. For CFOs managing utilization and project margins, late or miscoded expenses directly hurt earned-value calculations and client invoicing accuracy.

What to look for in expense management for Deltek Vision

Direct Deltek Vision integration is essential so expenses sync to Vision's project-phase-task hierarchy without file imports or middleware. The tool should respect your Vision structure at the point of entry, coding at every WBS level and to the right reimbursable, direct or indirect account, not after the fact. Receipt capture for field staff should take seconds and need no app. Multi-level approval workflows should route expenses to the project manager, department lead, then controller to match your firm's delegation of authority. Reimbursable expense handling marks client-billable expenses at submission so they flow to billing in Vision without manual sorting. GSA per diem rates applied by location keep government contracts in policy. A complete audit trail links every expense to a timestamped receipt image, GL account, project coding and approval chain for defensible reporting.

A practical example

An electrical engineer drives to a client site for a design review and stops for fuel and a working lunch. At the gas station, she texts a photo of the receipt, and Vergo recognizes the transaction context. Within seconds, the expense is coded to the correct project, phase and task. At lunch, she does the same with the restaurant receipt, and it is coded reimbursable because the client agreement covers meals during on-site work. Her project manager sees both expenses that afternoon and approves. The transactions sync into Vision, coded to project-phase-task and ready for the next billing cycle. The controller never touches a spreadsheet, the client invoice picks up the reimbursable meal, and the audit file has the timestamped receipt images behind each entry. What used to take a week of back-and-forth now happens as the spending occurs.

How Vergo handles this

Vergo integrates with Deltek Vision, syncing coded expenses directly into your project-phase-task hierarchy without file imports or re-entry. Employees handle everything by text message with no app to download and no portal login, texting receipt photos and submitting in seconds while Vergo chases missing receipts itself. Vergo proposes the coding by inference from your Vision accounting structure and history, with no rule library to build and no keyword lists to maintain; 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, routing by GL account, by amount, or by project, or you can skip approval flows 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 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.

Does the AI read the receipt, or just the header?

This is where AI-native coding separates from OCR. OCR lifts the vendor, the date and the total off the top of the receipt, then hands the coding back to a person. Vergo reads the receipt itself, line by line, and predicts the coding from what was actually bought — the project, the phase and the task — not just the vendor name on the header. One equipment-supply order can split across several projects and tasks, and header-level capture cannot see that. Every coding shows why it was chosen, so review means confirming in seconds rather than re-coding by hand.

Related questions

Can the software predict the coding from a receipt?

Yes. Vergo reads the receipt itself, line by line, and predicts the coding from what was actually bought — the project, the phase and the task — not just the vendor name on the header. A reviewer confirms rather than codes, and the reasoning is shown alongside each suggestion.

Frequently Asked Questions

Does Vergo sync expenses directly to Deltek Vision without import files?

Yes. Vergo integrates with Deltek Vision and syncs approved expenses directly with full project-phase-task coding. No spreadsheet exports, no manual imports. Each expense carries its receipt image and approval history, maintaining a complete audit trail for every entry.

Can engineers submit expenses from a client site on their phone?

Yes. Engineers text a photo of the receipt, with no app to download. Vergo codes it against your active Deltek Vision projects, so every expense lands on a valid project, phase and task. That removes late submissions and the miscoding that comes with end-of-month batch entry.

How does Vergo handle reimbursable expenses for client billing in Vision?

Vergo codes reimbursable expenses as reimbursable when they are submitted. When the expense syncs to Deltek Vision, that status carries through so billing staff can pull those charges into client invoices. It removes the manual sorting that delays billing cycles at many engineering firms.

What approval workflows does Vergo support for engineering firm expenses?

Vergo supports multi-level approval routing based on project, GL account, amount or any combination. A typical engineering firm routes expenses to the project manager first, then to the controller for final approval. Thresholds can escalate large expenses to a CFO or principal automatically.

Can Vergo apply GSA per diem rates for government engineering contracts?

Vergo applies per diem policies set to your rules, including GSA rates by travel location, and flags expenses that exceed them. That helps engineering firms on federal or state contracts keep travel spend within allowable limits and cuts the manual lookups controllers do during expense review.
