How do I connect AP automation to Foundation Software for construction invoices?

Key takeaways

• Vergo integrates with Foundation Software to sync AP invoices directly into job costing and general ledger, coding by inference from your existing cost code structure with no manual rule setup.
• Foundation Software integration requires admin credentials, a defined cost code structure, and an approval workflow that fits your construction projects.
• Successful AP automation depends on mapping your job, phase, and cost code hierarchy so invoices route correctly through Foundation's job costing modules.
• Field team adoption is critical—project managers and superintendents must understand how to submit invoices and receipts through the new workflow.
• A pilot phase on one project helps identify integration issues and cost code mapping errors before scaling across all jobs.

What you need before connecting AP automation to Foundation Software

You'll need full admin access to your Foundation Software instance to configure integration settings and user permissions. Your cost code structure—including job numbers, phases, and cost codes—should be documented and ready to map into the AP automation system. Define your approval hierarchy based on project, cost threshold, or GL account so invoices route to the right reviewers. Vergo's integration requires these same prerequisites but handles cost code mapping through inference rather than manual configuration. Involve project managers, field teams, and accounting staff early to secure stakeholder buy-in and plan training. Without these prerequisites in place, integration can stall or produce coding errors that require manual correction downstream.

How to implement AP automation with Foundation Software

Start by connecting your AP automation platform to Foundation Software using the available integration, mapping data fields to sync invoices with Foundation's job costing and AP modules. Configure cost code mapping so your job, phase, and cost code structure aligns between systems—this ensures invoices categorize correctly as they flow through. Set up approval workflows based on project, cost threshold, or other construction-specific criteria, then provision user access and permissions accordingly. Onboard field teams by training project managers and superintendents on invoice submission through the new system. Pilot the workflow on a single project to test data sync, approval routing, and cost code accuracy before expanding to your full portfolio. Monitor processing time, adoption rates, and coding accuracy, then iterate on workflows and mappings as needed.

A practical example

A general contractor running five active projects in Foundation Software connects AP automation to streamline subcontractor invoices. They map their three-tier cost code structure—job number, phase code, and cost code—into the AP platform, then configure approval workflows so invoices under $5,000 route to the project manager and invoices above that threshold route to the controller. They pilot the workflow on one commercial project, submitting ten subcontractor invoices over two weeks. The pilot reveals that two cost codes were mapped incorrectly, causing invoices to post to the wrong phase in Foundation. After correcting the mappings, they roll out the workflow to the remaining four projects and reduce invoice processing time from an average of five days to under two.

Common pitfalls when connecting AP automation to Foundation

Ignoring field team adoption is the most common failure point—project managers and superintendents who don't understand the new process will continue submitting paper invoices or bypassing the system. Incorrect cost code mapping between the AP platform and Foundation Software leads to invoicing errors, rework, and delayed payments to vendors. Skipping the pilot phase and scaling immediately can cause widespread disruptions if integration issues or workflow misconfigurations go undetected. Inadequate ERP integration—missing data fields, poor sync timing, or incomplete API connections—creates data silos that require manual reconciliation and undermine the automation's value.

How Vergo handles this

Vergo integrates with Foundation Software and every other ERP and accounting system, syncing AP invoices directly into your job costing and general ledger. The platform codes invoices by inference from your own cost code structure and history—no rule library to build, no keyword lists to maintain, and 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: route by GL account, by amount, or by project, or skip approval flows entirely and let policy flags catch only what breaks a rule. Transactions are ready to code the moment they happen, and once they clear, they sync into Foundation Software. Card spend, employee reimbursements, and AP invoices run through one coding model—same coding, same review, one reconciliation—and payment stays on the rails you already use.

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 job, the phase and cost code, and the cost type — not just the vendor name on the header. One run to a supply house can be several cost codes across its lines, 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.

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 job, the phase and cost code, and the cost type — not just the vendor name on the header. A reviewer confirms rather than codes, and the reasoning is shown alongside each suggestion.
