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 manual re-entry, enforces WBS-level job costing, and syncs coded transactions directly into Vision without CSV imports.
Field engineers should submit receipts in seconds without logging into desktop interfaces, and reimbursable expenses must be flagged for client billing as they occur.
Complete audit trails linking receipts, GL codes, project codes, and approvals are essential for government contract compliance 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 field teams. Engineers traveling to job sites, attending client meetings, or purchasing materials shouldn't need to log into Vision's desktop interface to submit a receipt. The result is predictable: delayed submissions, miscoded expenses, and controllers chasing down project charges at month-end. Common problems include expenses coded to wrong project-phase-task combinations that distort job-cost reports, per diem and mileage entries submitted weeks late that skew profitability snapshots, AP clerks manually re-entering expense data from spreadsheets into Vision, no real-time visibility into reimbursable expenses that should be billed to clients, and audit trails that fail to connect receipt images to specific Vision transaction IDs. For CFOs managing utilization and project margins, late or miscoded expenses directly impact earned-value calculations and client invoicing accuracy.

What to look for in expense management for Deltek Vision

Native Deltek Vision integration is essential so expenses sync to Vision's project-phase-task hierarchy without CSV imports or middleware. The tool should enforce your Vision cost structure at the point of entry with WBS-level job-cost coding, not after the fact. Mobile receipt capture for field staff means engineers on-site can submit in under 30 seconds. Multi-level approval workflows should route expenses by project manager, department lead, then controller to match your firm's delegation of authority. Reimbursable expense flagging lets you tag client-billable expenses at submission so they flow into Vision's billing module without manual sorting. GSA and per diem rate compliance with auto-calculation by location keeps you compliant on government contracts. A complete audit trail links every expense to a timestamped receipt image, GL code, project code, and approval chain for defensible reporting.

A practical example

An electrical engineer drives to a client site for a design review meeting and stops for fuel and a working lunch. At the gas station, she photographs the receipt and the system recognizes the transaction context. Within seconds, the expense is coded to the correct project phase and task based on her current assignment. At lunch, she does the same with the restaurant receipt and flags it as reimbursable since the client contract covers meals during on-site work. Her project manager sees both expenses that afternoon and approves with a single tap. The transactions sync into Vision that evening, properly coded to project-phase-task, ready for the next billing cycle. The controller never touches a spreadsheet, the client invoice includes the reimbursable meal automatically, and the audit file has timestamped images linked to Vision transaction IDs. What used to take a week of back-and-forth now happens in real time with complete accuracy.

How Vergo handles this

Vergo integrates with Deltek Vision and every other ERP and accounting software, syncing coded expenses directly into your project-phase-task hierarchy without CSV imports or re-entry. Employees handle everything by text message with no app to download and no portal login, photographing receipts on-site 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.

Frequently Asked Questions

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

Yes. Vergo integrates natively with Deltek Vision's API, syncing approved expenses directly to Vision's AP module with full project-phase-task coding. No CSV exports, no manual imports. Receipt images attach to the Vision transaction record automatically, maintaining a complete audit trail for every expense entry.

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

Yes. Vergo's mobile app lets engineers photograph receipts and submit expenses in under 30 seconds. The app pulls active Deltek Vision project codes so field staff select valid WBS combinations on-site. This eliminates delayed submissions and reduces miscoding errors that typically occur with end-of-month batch entry.

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

Vergo lets staff flag expenses as reimbursable at the time of submission. When the expense syncs to Deltek Vision, the reimbursable tag carries through so billing coordinators can pull those charges directly into client invoices. This eliminates 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, department, expense 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.

Is Vergo compliant with GSA per diem rates for government engineering contracts?

Vergo supports GSA per diem rate tables and can auto-calculate allowable per diem by travel location. This helps engineering firms working on federal or state contracts stay compliant with FAR expense requirements and reduces the manual lookups controllers perform during expense review cycles.
