Invoice processing software: how to choose the right solution [2025 guide]

At a glance

Modern invoice processing software eliminates repetitive tasks, reducing manual effort spent on chasing approvals and cross-verifying data.

Accuracy improves because every step—from validation to approval—follows a standardized digital process, minimizing errors and duplicate payments.

Visibility increases through real-time dashboards that track progress, bottlenecks, and pending exceptions across finance teams.

Scalable, compliant operations become achievable as automated workflows connect with ERP systems and external vendors seamlessly.

Choose the right invoice processing software and learn how Moxo’s workflow automation layer complements ERP and AP systems to drive efficiency, compliance, and collaboration.

Invoice processing is at a crossroads

Despite decades of digital transformation, invoice processing remains one of the most manual finance workflows. Studies show that organizations spend up to $13 per invoice when relying on email or paper-based methods (as per APQC). Multiply that across thousands of transactions, and the cost of inefficiency is substantial.

At the same time, regulatory oversight, vendor expectations, and audit requirements have intensified. Businesses can no longer afford duplicate payments, missed discounts, or delayed approvals. Modern invoice processing software bridges the gap—combining automation, AI validation, and compliance visibility.

But the key challenge lies in choosing the right software—one that enhances ERP capabilities rather than duplicating them.

‍

Why traditional AP tools fall short

ERP and AP systems manage accounting well but lack flexibility for human-driven, external workflows. Consider how most finance teams still operate:

• Approvals happen over long email chains.
  
  
• Validation requires manual cross-checks.
  
  
• Exceptions in two- or three-way matching delay payments.
  
  
• Vendors have no real-time visibility into invoice status.
  
  

This fragmentation leads to bottlenecks, compliance risks, and poor vendor experiences.

A mid-sized CPA firm, for instance, struggled with scattered invoice approvals across multiple clients. After adopting a workflow-driven portal built on Moxo, they reduced processing time by 54%, minimized duplicate entries, and improved client satisfaction scores.

The takeaway is clear: automation alone is not enough. Businesses need connected workflows that combine structure, visibility, and accountability.

‍

What category are you buying?

Not every tool marketed as invoice processing software serves the same purpose. Understanding categories helps prevent overlap and ensures the right fit:

ERP/AP modules: Built into systems like SAP, Oracle, or NetSuite. Great for accounting, limited for external collaboration.

Point solutions: Offer OCR and basic automation but often lack scalability or deep integration.

Workflow automation software: Platforms like Moxo extend ERP/AP functionality with external collaboration, secure approvals, and end-to-end visibility.

Choosing the right category depends on whether your goal is to enhance existing systems or to completely replace manual workflows. Most high-performing finance teams choose augmentation—adding a workflow layer like Moxo to complement existing ERP investments.

Evaluation criteria: How to choose the right invoice processing software

When evaluating solutions, look beyond automation claims. The best software combines flexibility, intelligence, and compliance. Here’s how to evaluate—and how these criteria map to Moxo’s capabilities.

Flow builder: human steps and approvals

Invoice processing requires multiple human touchpoints—finance, operations, compliance. A no-code flow builder enables teams to map these steps easily.

Moxo’s workflow builder allows businesses to create approval hierarchies, escalation paths, and reminders, ensuring accountability without email clutter.

Two/three-way match exceptions

Exceptions occur when invoice, PO, and receipt data don’t align. Moxo automates exception routing to relevant stakeholders and maintains a complete digital audit trail for compliance teams.

Integrations (ERP/AP, DMS, eSign)

An invoice processing tool must connect seamlessly with core systems. Moxo’s integrations with ERP, DMS, and e-signature platforms ensure end-to-end continuity without data duplication.

Magic links and notifications

Moxo’s Magic Links enable vendors or clients to submit or approve invoices securely—without logging into a portal. Instant notifications ensure every participant stays informed, reducing follow-ups.

SSO/SAML and audit trails

Security and compliance are essential. Moxo’s bank-grade security framework includes SSO/SAML, SOC 2 and GDPR compliance, encryption, and detailed audit logs—providing both control and transparency.

Management reporting

CFOs need visibility across metrics like cycle time, exception rates, and payment status. Moxo’s reporting dashboards give leaders actionable insights to identify bottlenecks and improve ROI.

Evaluate your shortlist with this checklist

Before finalizing your vendor shortlist, use these practical evaluation questions:

• Does the software support multi-level human workflows?
  
  
• Can it automate validation and exception routing with AI?
  
  
• Does it integrate seamlessly with ERP/AP systems?
  
  
• Are audit trails and security standards (SOC 2, SSO/SAML) in place?
  
  
• Can vendors and clients collaborate externally without login friction?
