Introduction
Small and medium businesses, CFOs, and finance managers face constant pressure to close books faster, maintain cash flow, and control costs. Online accounts payable services transform traditional accounts payable by moving the accounts payable process into a secure, automated, cloud-based environment. By adopting online accounts payable services, you can automate invoice processing, streamline payment process workflows, and free your AP department from repetitive tasks, letting your AP team focus on supplier relationships and strategic accounts payable management.
What are online accounts payable services?
Online accounts payable services are cloud-based accounts payable solutions and managed services that automate accounts payable workflows from invoice capture through payment. These services combine accounts payable software, automation platforms, and often managed services or outsourcing accounts payable services to deliver end-to-end accounts payable process automation. Typical online accounts payable services include invoice processing, approval workflows, purchase order matching, payment scheduling, and integration with accounting software and ERP systems.
Related terms to know
This article uses related terms such as cloud-based AP services, online invoice processing, virtual accounts payable solutions, digital AP automation, accounts payable automation, AP automation solution, and accounts payable outsourcing services to describe complementary approaches and capabilities.
Key benefits of online accounts payable services
1. Speed: Faster invoice processing and payments
Automating the accounts payable process reduces manual data entry and accelerates the accounts payable process. Online accounts payable services use optical character recognition (OCR), machine learning, and robotic process automation to extract invoice data and route it through automated AP workflows. That means invoices are validated, approved, and processed faster, reducing cycle times and enabling timely payments that can secure early payment discounts.
2. Accuracy: Fewer errors, improved audit trails
Manual AP is error-prone: miskeyed amounts, lost invoices, and inconsistent coding. An accounts payable automation solution standardizes invoice processing and captures data accurately, decreasing invoice exceptions. All changes and approvals are logged, creating a clear audit trail and simplifying month-end close and compliance.
3. Visibility: Real-time tracking and reporting
Online accounts payable services provide dashboards and reports showing invoice status, pending approvals, and cash requirements. Visibility into the accounts payable workflow helps CFOs forecast cash flow, prioritize payments, and manage supplier relationships. Integration with your accounting software or ERP ensures a single source of truth across payable systems.
4. Cost savings: Reduce headcount and late fees
Automation reduces the time AP staff spend on routine tasks, cutting labor costs and lowering per-invoice processing costs. Avoiding late payments avoids fees and maintains supplier goodwill. For businesses considering accounts payable outsourcing solutions, online services can further reduce costs by providing shared infrastructure and specialized teams.
5. Scalability and flexibility
Cloud-based accounts payable solutions scale with business needs. Whether you process dozens or thousands of invoices monthly, online accounts payable services adapt without major IT investments. Mobile approvals, integrations, and configurable workflows let you tailor the AP process to your business.
In-house AP vs online/outsourced accounts payable services
Deciding whether to keep accounts payable in-house or to adopt online accounts payable services or accounts payable outsourcing services depends on business size, complexity, and strategic priorities.
In-house AP (traditional)
- Pros: Direct control over payables, internal knowledge of supplier relationships, and immediate access to documents.
- Cons: Higher labor costs, slower invoice processing, risk of errors, limited scalability, and heavy IT/support burden if using on-premise systems.
Online accounts payable services (cloud-based or hybrid)
- Pros: Faster deployment, continuous updates, automation features (OCR, RPA), easier integrations with accounting software, mobile approvals, and improved visibility.
- Cons: Dependence on vendor SLAs and internet availability, ongoing subscription costs, and initial change management.
Outsourced/accounts payable outsourcing companies
- Pros: Turnkey solution with managed services, reduced headcount burden, operational expertise, and potential cost predictability.
- Cons: Less direct control, potential data security concerns, need for strong governance, and SLA management.
Choosing the right model
Many organizations adopt hybrid approaches: retain strategic AP functions in-house (supplier relationships, exceptions) while outsourcing or using online accounts payable services for invoice processing and payments. Assess your business needs, current accounts payable process maturity, and available resources to determine the best path.
Essential features to look for in online accounts payable services
When evaluating online accounts payable services, prioritize features that address speed, accuracy, visibility, and integration.
1. Invoice capture and processing automation
Look for OCR, machine learning, and prebuilt data extraction to automate invoice capture. The best accounts payable software improves accuracy over time and reduces manual validation.
2. AP workflow and mobile approvals
Configurable approval rules, delegation, and mobile approval capabilities keep the AP workflow moving even when approvers are remote. This accelerates the approval process and prevents bottlenecks.
3. Purchase order matching and exception handling
Automated three-way matching (invoice, purchase order, receipt) reduces exceptions. When there are mismatches, the system should provide clear tools for resolution and workflow routing.
4. Payment process automation
Integrated payment capabilities, including ACH, virtual cards, and check printing, enable secure and auditable payments. Payment scheduling and approval controls help manage cash flow.
5. Integrations with accounting software and ERP
Seamless integration with your accounting service, ERP, and banking systems prevents duplicate data entry and keeps your general ledger up-to-date.
6. Reporting, dashboards, and analytics
Real-time insights into days payable outstanding (DPO), invoice aging, and cash requirements empower finance leaders to make data-driven decisions.
7. Security, compliance, and audit trails
Choose providers that meet industry security standards, offer role-based access, and provide detailed audit logs for compliance and risk management.
8. Scalability and vendor support
Verify that the accounts payable service provider can scale with volume and offers strong onboarding and ongoing support, whether you adopt an automation solution or a managed service.
Common challenges and mistakes to avoid
Even with the best technology, organizations can fall into pitfalls when adopting online accounts payable services. Avoid these common mistakes:
- Skipping process mapping: Automating a broken accounts payable process amplifies inefficiencies. Map and streamline workflows before implementing automation.
- Underestimating change management: Train staff and approvers, communicate benefits, and provide clear documentation to drive adoption.
- Poor integration planning: Failing to integrate with accounting software or purchase order systems leads to duplicate work and reconciliation issues.
- Ignoring supplier onboarding: Suppliers must be able to submit invoices in supported formats; invest in supplier enablement to reduce exceptions.
- Focusing only on cost: Prioritize long-term value accuracy, visibility, and compliance over short-term price considerations.
Step-by-step guide to selecting and implementing online accounts payable services
Step 1: Define business goals and metrics
Determine what success looks like: reduce invoice processing time by 10%, lower per-invoice cost, improve on-time payments, or cut DPO to a target. Establish KPIs to measure outcomes.
Step 2: Map your current AP process
Document your accounts payable workflow, from invoice receipt to payment, including exceptions and manual tasks. Identify pain points that automation must address.
Step 3: Set requirements
Create a list of required features: OCR invoice processing, AP workflow automation, purchase order matching, payment modes, accounting software integrations, security, and mobile approvals.
Step 4: Evaluate providers
Shortlist accounts payable service providers and software solutions. Consider cloud-based AP services, AP automation software vendors, and accounts payable outsourcing companies, depending on whether you want managed services. Evaluate demos, customer references, and case studies focused on similar business needs.
Step 5: Run a pilot
Start with a pilot for a subset of suppliers or invoices to validate the solution’s invoice processing accuracy, integration behavior, and AP workflow performance. Gather feedback from AP staff and approvers.
Step 6: Plan integrations and data migration
Work with IT and your vendor to integrate with accounting software, ERP, and banks. Migrate supplier data and establish mapping for GL codes and purchase orders.
Step 7: Supplier enablement
Communicate changes to suppliers, provide submission options, and offer onboarding support. Supplier adoption significantly reduces exceptions and improves first-pass processing.
Step 8: Train users and monitor KPIs
Provide role-based training for AP staff, managers, and approvers. Monitor KPIs and adjust workflows, rules, and thresholds to improve performance.
Step 9: Scale and optimize
After successful rollout, expand the service to more suppliers, automate additional payment types, and use analytics to uncover further savings opportunities.
