What is a Paperless Invoice Approval System?
A paperless invoice approval system is a digital solution that automates the process of receiving, reviewing, and approving supplier invoices without the need for physical paperwork. Instead of relying on printed invoices, email threads, or manual signatures, businesses can use software to manage the entire approval workflow electronically.
Why do you need to switch to a paperless invoice approval system?
Convenience, speed, cost-effectiveness, and accuracy are just a few reasons why you should make the switch to paperless invoice approvals.
This system typically includes features like digital invoice capture, workflow routing, approval hierarchies, and integration with accounting software. It not only enhances efficiency and accuracy but also supports organizations in complying with audit and record-keeping requirements. By streamlining accounts payable processes, a paperless system helps reduce costs, speed up vendor payments, and eliminate data silos.
In this blog, we will explore how to implement a paperless invoice approval system, the benefits it offers, key components to consider, common challenges to avoid, and the best tools available today.
What does a Paper-based Invoice Approval System look like?
In the words of the Controller, QSR Restaurant Franchise Operator, a paper-based invoice approval system looks like this –
After we paid everything, we would go back and double-check. So we would look at what was on the paper and what we keyed and highlight it, to make sure it was right. If we missed it that way, and it got posted, and it got found later down the line, we’d have to do an adjustment in our accounting system, which took a little while. But it was another step.
We probably looked at the invoices five or six times before we were finished with them — between opening them, sorting them, coding them, keying them, checking them, and scanning them. Yeah, we went through them a whole bunch of times. We would look at one piece of paper, like, a lot.
Why Businesses Should Transition to a Paperless Invoice Approval Process
For decades, finance teams have relied on paper invoices, spreadsheets, and physical files to manage vendor payments. While this method may seem familiar, it is fraught with inefficiencies, including misplaced documents, delayed approvals, and high administrative costs. A paperless invoice approval process solves these issues by digitizing the entire workflow.
The cost of processing a single invoice through a manual, paper-based system comes to $16 USD. Costs associated with manual invoice processing include labor costs, infrastructure costs, physical goods costs, and transaction fees. When we factor all of these costs, the total cost of manual invoice processing amounts to $1.42 per invoice (for companies in the 25th percentile) and $6 per invoice for bottom performers.
One of the most compelling reasons to adopt a paperless process is speed. Digital invoices can be routed instantly to approvers, reducing delays that often occur when physical documents sit on desks or in inboxes. This also improves cash flow management by allowing companies to take advantage of early payment discounts. CFOs of global businesses are switching to paperless invoice approval systems. Why? Independent studies show that AP automation and paperless invoice approval systems can reduce invoice processing costs by up to 80% and shorten approval times by 50-75%.
Another advantage is visibility. With real-time tracking and centralized dashboards, finance managers can see exactly where each invoice is in the approval process. This reduces the risk of duplicate payments, missed deadlines, and compliance violations. Additionally, the reduction in paper usage aligns with sustainability goals, making this transition not only a smart business move but also an environmentally responsible one. Transitioning to paperless AP processes also offers substantial environmental benefits by reducing paper usage and decreasing the carbon footprint.
How to Implement a Paperless Invoice Approval System Effectively
Implementing a paperless invoice approval system is a strategic process that involves multiple steps. Each step is essential to ensure that your transition from manual to digital invoicing is successful, compliant, and sustainable.

Benefits of a Paperless Invoice Approval Process for AP Teams
Adopting a paperless invoice approval process revolutionizes how accounts payable (AP) teams operate, shifting them from manual, reactive work to strategic, high-impact roles. These benefits span efficiency, accuracy, control, and vendor satisfaction.
First and foremost, it drastically reduces processing time. In traditional environments, invoices often pass through several hands before approval, leading to lost documents and delayed payments. With a digital system, routing is instant, and approvals can be completed in real time—even remotely. This reduces approval cycle time from days to hours, ensuring vendors are paid promptly and early payment discounts can be captured.
Second, accuracy significantly improves. Digital systems use OCR to eliminate manual data entry, which is one of the leading sources of invoice errors. These platforms also validate entries against purchase orders and goods received notes, automatically flagging mismatches for resolution. As a result, fewer discrepancies arise, and the need for rework or exception handling is minimized.
Third, it enhances visibility and accountability across the invoice lifecycle. Every step—from receipt to approval—is logged in an audit trail. This level of transparency enables finance managers to monitor workflow bottlenecks, ensure timely approvals, and enforce compliance with internal policies and external regulations. It also simplifies audits by maintaining a searchable, well-organized history of all invoice transactions.
Fourth, AP teams experience greater control over spend and budget management. Real-time dashboards provide insights into outstanding liabilities, pending approvals, and upcoming due dates. This information supports accurate cash flow forecasting and allows finance leaders to make informed spending decisions.
Fifth, vendor relationships improve through consistent communication and faster payments. Suppliers appreciate predictable timelines and can access status updates without repeated email follow-ups. This builds trust, reduces invoice disputes, and positions the company as a preferred customer.
Finally, automation frees AP teams from repetitive, low-value tasks such as printing, filing, and chasing signatures. Instead, they can focus on strategic initiatives like spend analysis, process optimization, and vendor negotiations, enhancing the overall impact of the finance function.
The shift to a paperless invoice approval process transforms AP from a reactive cost center to a proactive business enabler, delivering measurable value across the organization.
Key Components of a Digital Invoice Approval System
A robust paperless invoice approval system is built on several essential components that work together to streamline the process:
- Digital Invoice Capture: Invoices are received via email, upload, or scanning. OCR tools extract data, removing the need for manual entry and minimizing errors.
- Custom Workflow Routing: Based on rules such as invoice amount, department, or vendor, invoices are automatically routed to the correct approver.
- Approval Hierarchies: Multi-level approvals ensure that invoices above a certain threshold are reviewed by senior personnel. This maintains compliance and control over spending.
- Real-Time Dashboards: Managers can track invoice statuses, monitor bottlenecks, and view KPIs like cycle time and approval delays.
- ERP Integration: Seamless syncing with financial systems ensures that once invoices are approved, they are automatically pushed to the accounting system for payment processing.
- Audit Trail and Reporting: Every step, comment, and approval is logged, providing full visibility and compliance with internal and external standards.
These components ensure that the entire invoice lifecycle is digitized, tracked, and optimized from start to finish.
Common Challenges in Paperless Invoice Processing and How to Overcome Them
While paperless invoice processing brings immense advantages, companies often face certain hurdles during implementation. One major challenge is resistance to change. Employees accustomed to manual processes may hesitate to adopt a digital tool. This can be addressed by providing adequate training, highlighting time-saving benefits, and involving users early in the implementation process.
Another issue is data inconsistency. If supplier information is incomplete or invoice formats vary, it can disrupt automated routing. To mitigate this, standardize data formats and regularly update vendor master records. Using OCR with machine learning can also improve data accuracy over time.
Technical integration with existing systems can also be complex, especially in organizations with legacy infrastructure. Choosing a flexible platform that supports integration with common ERPs and provides APIs can help smooth this transition.
Finally, weak internal controls may surface during digitization. Ensure that clear approval workflows, user permissions, and segregation of duties are built into the system from the start to avoid compliance risks.
