Tracking committed costs requires mapping approved POs and subcontracts against invoices received, then monitoring the variance by cost code throughout the project lifecycle. Vergo's AP automation workflow maintains this committed-vs-invoiced ledger in real time, flagging overbillings and syncing updated WIP exposure directly to your ERP.
The Current Problem
In construction, there is often a significant gap between the costs your team has committed to (purchase orders, subcontracts) and the actual invoices that come through. This makes it challenging to accurately forecast project cash flow and manage budgets. The breakdown typically happens at the handoff between the field team and accounting.
- Field staff don't consistently track or report committed costs
- Accounting lacks visibility into outstanding commitments
- Invoices arrive piecemeal and aren't matched to original commitments
- Lacking this connection, you can't see the true project financial picture
The Recommended Workflow
- Require field staff to log all purchase orders and subcontracts in your centralized system (ERP, construction management software).
- Set up automatic syncing between your field system and accounting system so all commitments are visible.
- As invoices come in, match them to the original commitments using PO numbers, cost codes, etc.
- Flag any variances between committed and invoiced amounts for review and approval.
- Report on the gap between committed and invoiced costs for each project.
- Use this data to manage cash flow, forecast project financials, and optimize future subcontractor negotiations.
Tips for Construction Teams
- Train field staff on the importance of logging commitments accurately and consistently
- Provide mobile tools to make it easy for them to track POs and subcontracts on the go
- Establish a clear policy around commitment approvals and invoice matching
- Automate as much of the AP process as possible to reduce manual effort
- Integrate your ERP, project management, and accounting systems for a connected view
- Use software like Vergo to streamline committed cost tracking and AP automation
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.

Frequently Asked Questions
What if a subcontractor invoice doesn't exactly match the original PO?
If there are variances, flag them for review by the project manager. They can approve the invoice, adjust the commitment, or request a credit/change order from the subcontractor.
How do I handle commitments that span multiple projects or cost codes?
Set up your ERP or construction management system to allocate commitments across multiple jobs or cost codes. This ensures you have full visibility, even for complex procurement.
Can I track committed costs on a per-project basis?
Absolutely. Organizing your commitments, invoices, and variance reporting by individual project is key for cash flow management and project cost control.
What about one-time purchases that don't have a PO?
Even for ad-hoc purchases, you should require a digital approval workflow and integrate that into your AP process. This maintains a paper trail and keeps commitments visible.
