Vendor invoices arrive by email, get matched to the Vista PO, checked against what was actually delivered, routed to the right approver, and posted as AP invoices coded to job, phase code, and cost type. 90% less PO and invoice processing time.
Viewpoint Vista is a construction ERP with tools for accounting, HR, project management, equipment management, and service management. Field Materials doesn't replace any of it — it automates the purchasing and AP work.

Every invoice type, coded correctly
Because invoices clear in days rather than weeks, project managers see committed, received, invoiced, and paid costs against the Viewpoint Vista budget while the job is still running — not after the period closes.
AP automation for Viewpoint Vista is software that receives vendor invoices, matches them to Viewpoint Vista purchase orders and delivery records, codes them to the right job and cost code, routes them for approval, and posts them into Viewpoint Vista without manual data entry. Field Materials provides AP automation and purchase orders for Viewpoint Vista, handling the work before a transaction reaches your accounting system.
Viewpoint Vista doesn't include AP automation, and it does not capture delivery records from the field or check invoice lines against received quantities. Field Materials adds that layer. Crews photograph packing slips on delivery, each invoice line is matched against both the Viewpoint Vista purchase order and what actually arrived, and only verified, coded records post to Viewpoint Vista.
Field Materials reads every line of the invoice, matches it to the Viewpoint Vista purchase order, and applies the job, phase codes from that purchase order. Invoices with no PO are coded from the vendor's default or from past invoices, and a single invoice can be split across several cost codes or jobs. Project managers see committed and actual costs against the Viewpoint Vista budget while the job is still running.
Yes -- Field Materials matches each invoice line against both the Viewpoint Vista purchase order price and the quantity actually delivered. Field crews photograph packing slips in the mobile app, which creates the received-quantity record. Price and quantity discrepancies are flagged before the invoice posts to Viewpoint Vista. This is a true three-way match, not a header-total check.
