AP automation in NetSuite: a guide to better invoice and payment processing

Modern accounts payable (AP) teams often use tools and techniques that are anything but modern. They use spreadsheets to track and enter expenses, manually match invoices to purchase orders and reconcile vendor statements by hand. These practices are not only outdated, but they also create inefficiencies and errors that force finance professionals to work overtime, while creating blind spots in reporting.

AP automation transforms how businesses manage their operations, helping teams like yours improve accuracy, speed up payments and streamline their workflows. These benefits are particularly acute if your business uses NetSuite, thanks to several advanced automation capabilities that are deeply integrated into the ERP software.

In this guide, we'll explore the essentials of AP automation in NetSuite, focusing on key integrations and their role in helping you streamline invoice processing from start to finish.

Key highlights:

• Manual AP processes create inefficiencies, errors and delays that hold finance teams back from operating at scale.
• Implementing AP automation in NetSuite improves accuracy, accelerates invoice processing and enhances financial visibility.
• Clear implementation steps and change-management practices are essential to overcoming adoption hurdles and realizing ROl.
• Zone & Co delivers purpose-built NetSuite AP automation tools that streamline workflows and maximize long-term business value.

What is AP automation?

AP automation uses technology to streamline the accounts payable function, from invoice receipt to payment, by eliminating manual intervention wherever possible. Using scan and capture, artificial intelligence (Al), purchase order approval workflow and invoice approval workflow tools, AP automation streamlines several functions:

• Capturing invoice data
• Validating invoices against purchase orders and receipts
• Guiding invoices through defined approval processes
• Assigning codes for the general ledger
• Initiating payment processing

The case for NetSuite AP automation

AP automation for NetSuite offers a wide range of benefits. Since the functions are carried out natively within the enterprise resource planning (ERP) system, it reduces manual data entry and improves the accuracy of financial operations. This approach helps prevent delays in invoice processing that lead to late fees, cash flow management issues and vendor relationship problems.

An integrated approach also brings your financial data together quickly, helping you:

• Gain insights early in the month
• Address issues before they escalate
• Improve the control you have over your financials

When AP automation is integrated directly into NetSuite, it gives you access to advanced capabilities, including real-time tracking and visibility into financial data, multi-currency support and advanced reporting.

Understanding the ROI of NetSuite invoice automation

One of the key reasons to consider AP automation for NetSuite is the potential return on investment (ROl) it provides, which is largely related to the productivity gains it creates. The following challenges for today's AP professionals are highlighted in a recent survey conducted by the Accounts Payable Association:

• 52.8% of organizations take more than 7 days to process an invoice from receipt to payment.
• About 17% of organizations report duplicate payments affecting more than 10% of invoices.
• More than 80% of organizations have faced fraud, with over a quarter encountering it monthly or more often.
• 32.6% face recurring compliance issues tied to tax, VAT or ESG reporting.
• Almost 1 in 5 lack a supplier vetting process.
• Over 15% of organizations struggle with significant missing or incorrect AP
  documentation during audits.

How automation helps teams overcome AP challenges

By automating your AP process, you can save time, reduce errors and free up your team to focus on more strategic work. That translates into cost savings for your business and faster returns on your investments in automation. Real-world results highlight the impact:

• Escalante Golf cut invoice entry time by 70%, reducing 300+ hours of manual work each month.
• Amigo Mobility freed up more than 700 hours annually, equivalent to four months of full-time work.
• Enviolo achieved 100% reconciliation accuracy and faster month-end closes, eliminating hours of manual effort at every close.
• EM de Jong eliminated duplicate entries and gained complete visibility across subsidiaries, improving audit readiness and team productivity.

In addition, businesses that deploy automation have reported several benefits that extend its value. They validate invoices much more quickly, reducing the financial impacts of fraud, duplicate invoice payments and expired credit notes. They also report fewer missed payments and late fees - and instead take advantage of early payment discounts. Not to mention, they can now forecast cash flow faster and more accurately than ever, and are reporting fewer payment problems with suppliers linked to AP issues.

Integrating automation with other financial processes, such as advanced revenue management (ARM), can further improve your ROl, particularly for companies with complex billing models. That's because ARM can reduce the manual effort required, improve accuracy and make compliance easier for accounts receivable teams.

When combined with automation solutions, ARM improves the visibility you have into your business's cash flow, which can inform decisions that truly improve your company's financial position.

Core components of NetSuite AP automation

Finance leaders often ask what AP automation in NetSuite actually looks like in practice. It comes down to the core components that remove manual work, reduce errors and create consistency in how invoices flow through your ERP.

Several features of NetSuite's AP automation make it a powerful tool for your business:

• Invoice capture automatically scans and extracts invoice data using optical character recognition (OCR) and Al technology. OCR eliminates the need for manual data entry, significantly speeding up your cycle time while reducing errors.
• Approval workflows route invoices to the appropriate stakeholders to expedite approval and ensure all required steps are completed before payments are scheduled.
• 3-way matching connects invoices to their respective purchase orders and receipts, reducing the need for manual verification and allowing finance teams to focus on exceptions.
• Automated coding assigns general ledger codes to invoices based on preset rules, reducing the risk of misclassification and ensuring consistency across transactions.

AP automation implementation for NetSuite: Key steps

Rolling out AP automation in NetSuite is only successful if it addresses the friction points AP teams deal with every day - invoices stuck in inboxes, approvers who never log in, mismatched POs and duplicate vendors. A strong implementation plan makes sure those problems don't just move from email to ERP.

1. Assess your current AP process

Trace an invoice from receipt to payment. Where does it stall - in a shared AP inbox, waiting for approvals or during PO matching? Document how many exceptions occur and why (missing POs, duplicate suppliers, unclear GL coding). This baseline ensures automation targets the right gaps.

2. Prepare and clean your AP data

OCR and coding rules only work as well as the data you feed them. Clean up vendor master records - merge duplicates like "Acme Ltd." vs "Acme Incorporated." Standardize PO formats and VAT/tax codes. Ask suppliers to use consistent invoice templates so automation doesn't get tripped up by formatting quirks.

3. Configure AP automation natively in NetSuite

Set rules that reflect how your AP team actually works with AP automation tools like Zone & Co's. Here are a few examples:

• Auto-assign GL accounts based on vendor type
• Apply tolerance rules for 3-way matching (e.g. invoices within 2% of PO auto-approve)
• Route invoices by department or spend threshold
• Enable email-based approvals for managers who rarely log into NetSuite

Keeping these rules native avoids the workarounds that plague bolt-on tools.

4. Roll out in stages

Start with invoice categories that are high-volume but simple - utilities, leases or subscriptions - to prove the process works. Once stable, move to complex vendor invoices like multi-line inventory POs which require tighter matching. A staged rollout prevents disruption and builds confidence across finance and operations.

5. Monitor and fine-tune your AP automation software

Measure what matters to AP:

• Average invoice cycle time
• % of invoices processed straight-through without manual touch
• Exception reasons (missing PO, duplicate vendor, approval bottlenecks)
• Late payment fees avoided
• Approvals stuck with a single approver

Use NetSuite dashboards and saved searches to track these KPls and adjust rules as needed. Continuous tuning is what sustains ROl.

Overcoming implementation issues of a NetSuite AP automation solution

Implementing AP automation in NetSuite can present issues around data quality, employee adoption and change management. It's important to ensure your data is accurate and standardized before implementing automation, as poor data quality can lead to errors and inaccurate financial reports. Automated invoice capture solutions like ZoneCapture can help improve data quality using OCR and generative Al technologies.

Another common hurdle is getting buy-in from employees who have grown comfortable with manual processes. To help ease the transition to AP automation, be ready to communicate clearly and provide thorough training. It also helps to choose automation systems that are flexible and can adapt to your business needs and operating practices.

One example of how an AP automation solution can be integrated into an organization's operating practices can be found in our case study with Escalante Golf. Their deployment allowed AP professionals to view relevant invoices without leaving the ERP or navigating external software. It also made uploading and coding easy and accurate by providing a side-by-side view of documents and their details. This not only reduced NetSuite invoice processing time for the company by 70% each month, but it also improved team morale.

The future of AP automation

AP automation is only increasing in sophistication. Solutions are evolving to provide deeper insights than ever before and integrate even more seamlessly with other financial processes, such as ARM and accounts receivable automation. New features are on the horizon that make it easier for your business to handle:

• Complex approval workflows
• International payments
• Customized vendor management tasks

In the not-too-distant future, these platforms will provide you with a comprehensive view of your business's financial health - in real time. And, of course, we must not forget Al and machine learning technologies. They're already driving advanced capabilities that improve data quality and streamline financial operations, and they're evolving quickly.

With the help of Al and machine learning, AP automation will soon help businesses further improve accuracy, detect anomalies and even prevent fraud.
