Field Materials pulls your QuickBooks projects, classes, items, and vendors, so POs go out itemized and mapped to the right QuickBooks items. Bills and expenses are then verified, approved, and posted. 90% less PO and invoice processing time.
QuickBooks Online is a leading accounting platform for small and mid-sized businesses, but it wasn't built for construction purchasing. Field Materials adds the project-level PO, delivery, and AP automations, without changing how your books 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 QuickBooks budget while the job is still running — not after the period closes.
AP automation for QuickBooks Online is software that receives vendor invoices, matches them to QuickBooks Online purchase orders and delivery records, codes them to the right job and QuickBooks items, routes them for approval, and posts them into QuickBooks Online without manual data entry. Field Materials provides AP automation and purchase orders for QuickBooks Online, handling the work before a transaction reaches your accounting system.
QuickBooks Online 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 QuickBooks Online purchase order and what actually arrived, and only verified, coded records post to QuickBooks Online.
Field Materials reads every line of the invoice, matches it to the QuickBooks Online purchase order, and applies the job, classes 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 QuickBooks Online budget while the job is still running.
Yes -- Field Materials matches each invoice line against both the QuickBooks Online 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 QuickBooks Online. This is a true three-way match, not a header-total check.
