FAQs About onPhase AP Automation Software
What does an onPhase AP automation implementation involve?
onPhase scopes every AP automation implementation to your invoice volume and existing accounting and ERP systems rather than running a one-size-fits-all rollout. It supports phased migrations and multiple integration methods, including API, secure file drop, and direct access, so your accounts payable team can bring the platform online in stages.
Which ERPs does onPhase integrate with natively, and what does that mean in practice?
onPhase connects directly with widely used ERPs including NetSuite, Microsoft Dynamics and Business Central, SAP, Sage, Acumatica, Procede, and CDK, with additional connections available. In practice, that means invoices, approvals, vendor records, and GL codes sync between onPhase and your ERP in real time, so your AP team runs the full accounts payable process in one system with no rekeying and no version-control issues.
How accurate is onPhase's AP automation invoice data capture?
onPhase's AP automation uses human-assisted AI to capture header and line-item invoice detail with up to 99% accuracy. Its smart capture reads complex invoice formats, handwriting, and multiple languages, and flags exceptions before they reach your ERP, reducing manual data entry for your accounts payable team.
Can we configure approval rules by amount, department, vendor, or GL code?
Yes. onPhase routes invoices through custom, rules-based invoice approval workflows that can be configured by amount, department, vendor, or GL code, so accounts payable approvals follow your organization's policies automatically. Routine invoices move straight through while exceptions are flagged for review.
What payment methods does onPhase support, and which earn cash back?
onPhase supports ACH, check, virtual card, and wire, all issued from within the same AP workflow and synced back to your ERP. Virtual card payments earn cash back on eligible transactions, turning accounts payable into a source of rebate revenue rather than purely a cost center.
How is onPhase AP automation priced?
onPhase AP automation pricing is tailored to your invoice volume, the modules you need, and your ERP integration requirements. Pricing is provided as a custom quote following a short scoping call or demo.
What compliance certifications does onPhase hold?
