Accounts payable best practices: 9 tips to optimize AP

When you talk strategy with your business partners, how often do you bring up accounts payable?

Few businesses think AP needs their attention unless something’s going wrong, but this couldn’t be further from the truth. Accounts payable can significantly impact your financials, affecting your cash flow, bottom line, reputation, and even opportunities in the market.

Fortunately, optimizing your accounts payable process isn’t complicated. With the right approach, your AP system can become a strategic asset—something we’ll explore through success stories after breaking down our top 9 best practices for accounts payable optimization.

Is accounts payable optimization worth it?

Before we dig into how to optimize your AP process, let’s talk about why it’ll be worth your time. Good accounts payable practices will:

• Increase efficiency: Implementing accounts payable best practices can reduce your AP processing workload, freeing your employees to focus on value-added tasks rather than compliance and manual processes.
• Reduce costs: AP best practices can help reduce your business’s cost per invoice. Better efficiency leads to cost savings on late fees, fraud containment costs, excess salaries, and more.‍
• Produce more accurate financials: When you perfect your AP process, your financials will be more accurate and up-to-date. This helps with bookkeeping and ensures better financial decision-making.
• Reduce fraud and cash mismanagement: Certain AP best practices can help prevent fraud and protect against losses resulting from negligence and cash mismanagement‍
• Improve vendor relationships: Adopting AP best practices will ensure your vendor payments are timely and accurate. When you prove you’re a reliable customer, your vendors and supplier relationships improve and they may be more likely to offer better payment terms or grant early payment discounts.
• Reduce stress: With the right AP strategies, you and your employees will almost never have to stress about missed due dates or late payments. And because your vendors and suppliers are happy, you won’t have to worry about fraying those key relationships.

Accounts payable best practices: 9 tips for improved AP processing

Optimizing your AP process is a big undertaking, so tackle it in chunks. Review the best practices below with your team and decide which one(s) to implement first. Prioritize the areas where you need the most help, then move on to the next one once you have the capacity. Even making one or two small changes can have a big impact on your organization.

1. Standardize your workflow

Create a workflow that describes exactly how you receive, approve, and process invoices. If you standardize your invoice approval workflow, you can look up the status of an order at any time. This ensures:

• All invoices are accounted for; no invoice is left behind
• Invoices are paid on time to the correct party—only once—in the correct amount
• Employees understand the workflow, preventing bottlenecks in the approval process
• There’s a record of how the invoice was managed
• Payments are recorded in your financial records
• You’ve taken advantage of early payment discounts and avoided late payment fees

2. Establish internal controls

Controls aren’t a thrilling topic, but keeping your invoicing system secure is necessary to safeguard against fraudulent activities. Internal controls for accounts payable can also provide better visibility into which employee—or which software—performed a task so you can trace errors and discrepancies to the source.

For example, your AP clerk, AP outsourcing provider, or automation software should perform a three-way match, outlined in an AP policy, by matching the purchase order to the receiving report and the invoice.

3. Go paperless

Encourage your vendors and suppliers to ditch paper invoices; if they won’t, digitize them yourself. You can use optical character recognition (OCR) software to scan invoices, read them, and pull relevant numbers into your system. Not only does going paperless for AP create a more reliable invoice record, but it also makes that invoice searchable.

4. Integrate

Centralize your financial data by ensuring your invoice management software is integrated into your other systems. This could include your accounting software, enterprise resource planning (ERP) software, customer relationship management (CRM) software, project management software, and expense tracking software.

5. Automate

Manually entering invoices is time-consuming, introduces inefficiencies, and can lead to costly errors. Automating your AP processes can ensure that the data in your system is accurate, reduce the chance of fraud, reduce the chance you’ll approve duplicate invoices, and help you avoid making duplicate payments or incorrect payments. A few AP automated solutions are:

• OCR for reading invoices, digitizing them, and extracting data from paper documents and PDFs
• Automated invoice approvals with 3-way matching
• Automated systems for procure-to-pay solutions
• Creating an audit trail

6. Build relationships with suppliers

If you haven’t already, create an open line of communication with your suppliers. Regular touches every now and then, even when you haven’t ordered in a while, can be a great way to build rapport. A good relationship puts you in a better position to negotiate early payment discounts or more flexible payment terms.

7. Understand your goals

Leverage your AP department to further your accounts payable goals. If your AP staff understands your vision, they can help guide you there. You can start by isolating KPIs that depend on your AP department, like cost per invoice, AP turnover ratio, or days payable outstanding (DPO). Then, empower your employees to help improve those numbers.

8. Train employees

When you use automation software to handle backend accounting functions, you might be tempted to think you can lighten up on employee training. But you shouldn’t overlook ongoing training; you might just need to adjust your focus.

Instead of training your accounts payable team to perform AP functions, you may just need to train them to use your AP software properly. Either way, whether you use automation software or perform all functions manually, your employees need to understand your AP workflow and why each task is being performed.

9. Keep good records

Businesses run on data, so good recordkeeping is essential. Invoice processing software will keep records of who approved the purchase order, processed the invoice, approved payment, and recorded the AP journal entry. The best software can also build accounts payable reports that help you make better strategic decisions surrounding AP.

How to monitor your AP process

Let’s say you’ve implemented many or all of the best practices we listed above. How will you know if your AP process is improving? You should review your AP data regularly.

The right software makes this much easier, allowing you to pull up the following metrics at any time:

• Overall financial performance: With accurate financials, you can be sure your payables balance is manageable relative to your working capital
• Outstanding payments: This report will help you see what payments are about to hit your cash account and when
• Short-term cash needs: This report will tell you your cash needs over the next week, two weeks, month, etc.
• Forecast future cash needs: Based on historical data, your software can predict your future cash needs over the next year, adjusting for seasonality and predicted materials cost increases
• AP metrics and KPIs: Software can calculate useful financial metrics like DPO, AP ROI, overdue payables, AP turnover ratio, average invoice processing time, and others
• Aging reports for accounts payable: AP aging reports can help you prioritize payments if cash reserves are tight, showing you which invoices have been unpaid longest
• Supplier invoice analysis: This report can show the average number of invoices (and average invoice amounts) from each supplier

Aside from hard metrics, you can monitor your AP process by simply talking to your employees. How does your AP department feel about the changes? Do they find their jobs easier or less stressful after implementing these solutions?

Crossbeam: Saving money on vendor contracts

Crossbeam, a rapidly growing technology company, faced a different challenge. Procuring new software often required hours of research to ensure they were getting the best value.
