procee

Budget and procurement management from the purchase request to the payment: a cloud layer on top of your ERP, with real-time budget control, approval routes and a supplier portal. Procee is a cloud procure-to-pay system for budget and procurement management, from the purchase request to the payment. It sits on top of the ERP you already run instead of replacing it, and syncs with it (Hashavshevet, Priority, SAP, Sage, Xero). The flow behind Procure to Pay and Invoice Management runs end to end in Procee, in one system: - Purchase requests with flexible approval routes (steps, approvers, conditions); approvers respond from email, mobile or the portal. - Purchase orders with real-time budget control: an order that exceeds the remaining budget line is blocked or flagged before the commitment is made. - A supplier portal where suppliers onboard themselves, upload invoices and delivery notes, match them to the purchase order and follow the status. - Invoice intake by upload, email or the supplier portal, AI-based OCR, 3-way matching against the order and the delivery, and export to accounting. - Payment batches that close the loop. Budgets are hierarchical (sort codes, baskets, allocations), with transfer requests that go through an approval route, multiple budgets and multi-currency support. Used by 200+ organizations. ISO 27001 and ISO 27017 certified. Free trial, no setup fee, no commitment.
