How do I sync expense data with ADP in a construction company?

Prerequisites Before You Begin

Before configuring any ADP expense sync, have these elements locked down:

• ADP admin credentials and API access. Your ADP account must have Workforce Now or Run API access enabled. Without this, no third-party integration can write data back to payroll records.
• A clean job and cost code list. Construction ERPs use a job > phase > cost code hierarchy. Export your active job list and confirm cost codes are current — stale codes create mapping errors that corrupt payroll allocations.
• Defined approval hierarchy. Decide whether expense approvals route by project manager, by job, or by dollar threshold before you build any workflow. Changing this post-launch requires reconfiguring every approval chain.
• Field user device inventory. Know what devices your field crews are using. Mobile submission behavior differs significantly between iOS and Android, and offline capture capability matters on remote job sites.
• Payroll processing calendar. Map your expense submission deadlines to ADP's payroll run schedule. Expenses submitted after the cutoff cannot be included in the current cycle — this must be communicated to crews before go-live.

Step-by-Step Implementation

1. Audit your current expense and payroll data flows. Document every place expense data is currently entered manually. Identify which fields in ADP correspond to which fields in your expense tool — commonly: employee ID, earnings code, job number, cost code, and amount.
2. Export and clean your job cost code master list. Pull the full job and cost code list from your construction ERP. Remove closed jobs, consolidate duplicate codes, and confirm phase codes align with how field crews actually describe their work.
3. Map expense categories to ADP earnings codes. Each expense type — mileage, per diem, materials, subcontractor receipts — must map to a specific ADP earnings or deduction code. Build a mapping table and get payroll sign-off before configuration.
4. Configure the integration between your expense platform and ADP. Use your expense tool's ADP connector or a middleware layer (such as a Workato or Zapier flow) to establish the data sync. Set sync frequency — real-time, daily batch, or per payroll cycle — based on your volume and payroll schedule.
5. Set up job code lookup for field users. Field employees should search for and select a job number at the point of expense capture. Configure your expense tool to pull live job data from your ERP so crews only see active, assigned jobs — not the full master list.
6. Build approval routing by project or cost threshold. At this stage, decide whether approvals route to the project manager on the job or to a centralized accounting approver above a dollar threshold. Both models are common in construction; the right choice depends on your project count and PM capacity.
7. Run a pilot on one active project. Select a mid-size project with an engaged PM and 5–10 field users. Run two full payroll cycles before expanding. Validate that ADP is receiving correct job allocations and that earnings codes are posting to the right accounts.
8. Train field crews and roll out company-wide. Provide mobile-first training focused on receipt capture and job code selection — these are the two failure points that generate the most resubmissions and corrections.

Common Pitfalls to Avoid

• Skipping the cost code cleanup before go-live. Importing a messy cost code list creates misallocations that require manual corrections in both your ERP and ADP — exactly the double entry you were trying to eliminate.
• Not involving project managers in approval workflow design. PMs who don't understand the approval chain will either bottleneck approvals or bypass them entirely. Get their input during Step 6, not after launch.
• Syncing ADP before your expense platform is stable. Configure and test the expense tool fully before enabling the ADP write-back. Partial data pushed to ADP during testing can corrupt payroll records.
• Ignoring offline capture for remote job sites. Field crews on sites without reliable connectivity will abandon digital expense submission if the app requires a live connection. Verify offline capture and sync-on-connect capability before rollout.
• Misaligning expense submission cutoffs with ADP payroll runs. If crews don't know the submission deadline, late expenses miss the payroll cycle and require manual off-cycle adjustments — the highest-cost exception in construction payroll.

How Vergo Simplifies This

Vergo's expense management platform is built specifically for construction and includes native integrations with all major construction ERPs — Sage 100/300, Viewpoint Vista/Spectrum, Procore, Foundation, QuickBooks, Acumatica, CMiC, COINS, Epicor, Jonas, and Deltek — as well as a direct ADP connector. The job code mapping described in Step 3 and Step 5 is automated through Vergo's ERP sync: active jobs and cost codes pull directly from your ERP into the mobile app, so field crews always see current, job-specific options without accounting having to maintain a separate list.

How Vergo Helps

Vergo is a card-agnostic expense management platform built for construction. Connect any corporate or project credit card and get full visibility and control over field spending.

• Job-cost coding at the point of capture — field teams assign job number, cost code, and cost type from their mobile device before the receipt leaves the job site.
• Per-job spend controls — set card limits by project, cost code, or cardholder so spending stays within approved budgets.
• Mobile receipt capture — superintendents and PMs photograph receipts on-site with automatic data extraction.
• Role-based approval workflows — route expenses through project managers, job-level approvers, and controllers based on your org structure.
• Vergo integrates natively with major construction ERPs, syncing coded expenses directly into job cost and general ledger without manual re-entry.
