All the AP Automation Features You Need in One Platform
onPhase delivers the full set of AP automation features modern finance teams need, including AI-powered invoice capture, intelligent approval workflows, PO matching, embedded payments, and real-time reporting and intelligence, on one cloud-based platform. 
Invoice Capture
onPhase's AI and human-in-the-loop validation work together to read header and line-item invoice details, including handwriting, with up to 99% accuracy. When the AI gets it wrong, onPhase's own team handles the exception before it ever reaches your AP team.
Automated Invoice Management
Validate and route invoices through approval rules as simple or as complex as your organization needs. Configure by amount, vendor, department, GL code, or location. See exactly where every invoice is in the process, and where it is getting stuck, before it becomes a problem.
PO and non-PO Matching
2-way, 3-way, and 4-way PO matching catches overpayments and discrepancies at the line level, before the approval step. Exceptions are flagged automatically. No more duplicate payments or missed short shipments.
Embedded Payments
Pay vendors without leaving the platform, so your team stays focused and efficient. Cash flow visibility is built in so you can see what's ready to pay, what's in process, and what's cleared in real time. That's real-time cash-flow visibility. Virtual card adoption generates rebates through your supplier network that can offset software costs. Suppliers can check payment status in the portal, which means fewer calls to your AP team and stronger vendor relationships
Reporting and Intelligence
Real-time reporting built into the platform gives finance teams live intelligence on their AP data from day one. No setup project. No data warehouse required.
Four pre-built dashboards are ready immediately: Invoice Aging shows where invoices are stuck by age and vendor, Approver Aging surfaces who is holding things up and what it is costing, Invoice Monitor tracks every invoice through the approval cycle in real time, and Vendor Spend Snapshot shows where every dollar goes by supplier and over time.
Supplier Communication
Communicate with suppliers directly inside the platform to resolve discrepancies, share payment status, and address open questions, without the email chain. Suppliers get real-time visibility into where their payment stands. Your AP team stays focused.
Built-In Security
SOC 1 Type II, SOC 2 Type II, HIPAA, and NACHA compliant. Role-based access controls, separation of duties, and a time-stamped audit trail on every capture, approval, and payment.
Seamless Integrations
onPhase integrates with the ERPs and dealer management systems (DMS) systems your team already runs, including NetSuite, Microsoft Dynamics, Procede, CDK, Karmak, Dealertrack, and Tekion, Sage, SAP, Infor, eand more!


A smarter way to manage invoices.
onPhase uses advanced AI to extract and validate invoice data with up to 99% accuracy. Our capture technology reads complex formats, handles line item detail, and flags exceptions before they reach your ERP.
Most AP automation tools reach 80 to 85% capture accuracy with AI alone. The remaining exceptions land on the AP team. With onPhase, those exceptions go to our human-in-the-loop team, so your team doesn't have to.
onPhase is built to connect by seamlessly integrating with your financial systems, workflows, and approval processes. From invoice intake to final approval, every step is automated, accurate, and auditable.
Take control of payments without slowing down your process
With onPhase, payments are embedded into the platform, providing your team even more visibility on cash flow. Once invoices are approved, your team is able to pay your suppliers without ever leaving the system.
Whether you’re issuing single payments or managing complex batch runs, onPhase gives you the flexibility to pay by ACH, check, virtual card, or wire. Built-in controls ensure compliance with your approval policies, while automatic holds protect against insufficient funds or missing documentation.


Built to work seamlessly with the ERP or DMS system you run today.
onPhase connects directly with the most widely used ERPs and dealer management systems (DMS) including NetSuite, Microsoft Dynamics 365, Business Central, Dynamics GP, SAP, Procede, CDK, Karmak, Tekion, Dealertrack, Sage, Infor, and more. Data flows bi-directionally between systems in real time, so invoices, approvals, and payments are always up to date. No rekeying. No version control issues.

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 integrates natively with NetSuite, Microsoft Dynamics 365 and Business Central, Sage, and Acumatica. For dealer management systems, onPhase is a certified API partner with Procede / Excede, CDK, Karmak, Dealertrack, Tekion, HBS, and DIS. Integration is bidirectional: invoices, approvals, vendor records, and GL codes sync in real time, so your AP team runs the full accounts payable process without rekeying data or managing version-control issues between systems.
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. Mid-market companies can route by entity, cost center, or business unit and build approval hierarchies that match their org structure without IT involvement. Mobile approvals and automatic delegation keep the workflow moving when approvers are out.
What payment methods does onPhase support, and how do rebates work?
OnPhase supports ACH, check, virtual card, and wire, all from within the same AP workflow and synced back to your ERP. Virtual card adoption generates rebates through your supplier network that can offset or exceed software costs. Once payments are released to onPhase, liability transfers to us. Built-in controls hold payments on insufficient funds or missing documentation before funds move.
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?
onPhase is SOC 1 Type II, SOC 2 Type II, HIPAA, and NACHA compliant, backed by more than 25 years supporting finance teams. For IT and security teams, SOC 2 Type II is typically the gate for vendor approval and covers data security controls, access management, and audit readiness. For healthcare organizations processing invoices alongside patient-adjacent financial data, HIPAA compliance applies to how that data is handled throughout the AP workflow. For finance leaders and treasury teams, NACHA compliance covers ACH payment processing. All implementations include role-based access controls, separation of duties, time-stamped audit trails, and automated payment holds.
Does onPhase integrate with dealer management systems like Procede, CDK, and Karmak?
How does onPhase handle invoice exceptions that are specific to my industry?
How does onPhase handle multi-rooftop or multi-entity AP operations?
onPhase is built for AP at scale across multiple locations and legal entities. Dealerships use it to centralize AP across 5 to 50+ rooftops, with each rooftop maintaining its own GL coding, vendor master, and approval rules, while the Controller or CFO gets a consolidated view across all locations in real time. Mid-market companies going through acquisitions or organic multi-entity growth use onPhase to standardize the AP workflow across new entities without rebuilding their ERP configuration. Approval hierarchies, vendor masters, and reporting dashboards can be set at the entity level, the location level, or rolled up company-wide. You add locations and entities without adding AP headcount.
