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