Every invoice type, coded correctly
Because invoices clear in days rather than weeks, project managers see committed, received, invoiced, and paid costs against the Spectrum budget while the job is still running — not after the period closes.
AP automation for Viewpoint Spectrum is software that receives vendor invoices, matches them to Viewpoint Spectrum purchase orders and delivery records, codes them to the right job and cost code, routes them for approval, and posts them into Viewpoint Spectrum without manual data entry. Field Materials provides AP automation and purchase orders for Viewpoint Spectrum, handling the work before a transaction reaches your accounting system.
Viewpoint Spectrum 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 Spectrum purchase order and what actually arrived, and only verified, coded records post to Viewpoint Spectrum.
Field Materials reads every line of the invoice, matches it to the Viewpoint Spectrum 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 Spectrum budget while the job is still running.
Yes -- Field Materials matches each invoice line against both the Viewpoint Spectrum 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 Spectrum. This is a true three-way match, not a header-total check.
