When your business is just getting started, you probably aren’t paying that many vendors.

However, as your company scales, this can quickly change. Some businesses consider outsourcing the accounts payable (AP) process to manage increased payable volume. 

This guide provides an overview of accounts payable outsourcing and when it might make sense for your business to consider this strategy.

What is accounts payable outsourcing?

Accounts payable outsourcing is when a business contracts with a third-party agency or external freelancer to handle some or most of the end-to-end accounts payable process.

AP outsourcing can either be an alternative or complement to having in-house finance staff overseeing AP processing or using AP automation software. 

For example, some businesses with an AP department might still work with an AP outsourcing agency, particularly if they have a significant month-to-month payment volume. 

This list below provides a good summary of the different tasks involved in accounts payable that a business might outsource: 

Process Description
Document management and data capture Receiving and filing purchase orders (POs), invoices, and other supporting documents, such as contracts, with the intent of facilitating payments.
Financial data entry and bookkeeping Creating bills, entering invoice data into payment processors or spreadsheets, and reconciling data in the accounting system or ERP.
Invoice matching Comparing purchase orders (POs), invoices, and shipping documents, before payment is sent to ensure goods and services have been received as described.
Approval workflows Sending invoices, PO (if applicable), and/or shipping receipts to the appropriate approvers who are authorized to review and approve the payment.
Payment Processing payments using preferred payment methods (ACH, check, credit card, etc.) and, where possible, securing early payment discounts.
Recordkeeping The documents, communications, and journal entries must be stored and available for review.
Reporting Management needs reports to manage cash flow and to monitor productivity.

Outsourcing providers automate payable functions to speed up processing, lower the risk of error, and offer a competitive price for AP processing.

If you consider outsourcing some or most of your AP process, it’s important to establish clear ownership of each of these steps to avoid any delays or other payment issues. 

Why do businesses consider AP outsourcing?

Businesses use AP outsourcing solutions for several reasons.  

You want to save money.

First and foremost, businesses sometimes outsource accounts payable as a cost-effective way to save money by reducing headcount and AP processing costs. 

Regarding employment benefits and back-office administration costs, AP outsourcing can be more affordable than increasing headcount costs by hiring a full-time staffer. 

Moreover, the human capital needed to process a single invoice using a third party will likely be lower than when a CFO or AP clerk processes it. 

Your finance staff is stretched thin.

Whether you have a one-person finance team managing 100 different fires or a robust finance organization, chances are that AP invoice processing is not top of the priority list. 

AP processing is considered a low-value-add activity, so businesses will often outsource AP to free up their in-house finance staff’s time for higher impact responsibilities like month-end close. 

An added benefit is that it can remove dependency bottlenecks and help your staff avoid feeling overworked and frustrated, a problem significantly impacting accounts payable departments.

You want to prevent fraud and ensure compliance.

Using an accounts payable outsourcing service provider can provide additional checks and balances that help your AP team process invoices on time, maintain positive vendor relationships, and enforce overall AP policy compliance. 

Every year, the AFP (Association for Finance Professionals) publishes an annual payments fraud survey.

The 2023 survey finds that 65% of organizations surveyed have been victims of payment fraud, with paper checks being the biggest culprit. This can typically happen when finance teams process electronic or paper invoices that appear valid but are sent by criminal actors. 

Having an extra set of eyes could also make your business less susceptible to this type of accounts payable fraud. In addition, accurate invoicing is a prerequisite to generating accurate financial statements. 

A system that generates duplicate payments — or pays fraudulent invoices — is unreliable, and the total accounts payable balance is likely incorrect. 

You want to improve your vendor relationships.

An AP process delayed by bottlenecks, payment discrepancies, or by lost data can quickly damage your relationships with your vendors, putting you at risk of losing key suppliers. 

You never want to have to rush to find a new supplier before a major event or shipment simply because a lost check caused your vendor to end your business relationship. 

By that same token, processing invoices on time and accurately could unlock opportunities for early payment discounts that boost your bottom line. 

10 pros & cons of AP outsourcing

First, let’s cover the advantages of using an accounts payable outsourcing company. 

Pros of outsourcing AP

1. More accuracy 

Outsourcing AP provides an extra layer of reviews that help ensure that errors are caught ahead of time. 

2. Lower cost compared to full-time hire

Even with accounts payable automation, the payment process can be time-consuming. Using a third party is often less expensive than hiring a full-time resource, like an AP clerk. 

3. Access to AP software tools

AP outsourcing agencies or contractors likely use AP automation and other financial technology to drive efficiencies and streamline the end-to-end AP process. 

By extension, hiring an AP outsourcing third party would help an organization derive benefits from the software the AP outsourcing firm is using. 

4. Reduces your team’s workload

If all goes well, outsourcing AP means that your finance team is no longer spending significant hours managing payable workflows, which frees up time for them to focus on higher-impact work. 

5. Improved vendor management

Working with an AP outsourcing partner can increase the likelihood that your payments are sent on time (or ahead of time), contributing to positive working relationships with your vendors. 

After all, improving vendor relationships is just a game of making sure they get paid on time, which is something that vendor management software can help with.

6. Manage cash flow more effectively

By outsourcing many of the manual AP tasks, you have more time to examine the bigger picture – key dates you’re sending invoices, what your cash outflows look like each day, discounts offered by vendors, and more. 

Potential cons of outsourcing AP

7. You may lose some control over the process

A trade-off you make whenever you bring on any agency or third party, AP outsourcing included, is that you tend to lose control over some of the process. 

But in many ways, that’s the point. You free up time for yourself by outsourcing a function for others to manage, so you can focus on higher priority items and strategy. 

By establishing clear communication and stringent reporting protocols with the outsourcing provider, you can maintain an appropriate level of oversight and thereby ensure a smooth operation.

8. You must be extra mindful of your data security practices

When outsourcing AP,  you must rely on the third-party provider’s security to protect your data.

That is why it’s essential that you collaborate with your IT and legal teams to ensure you and the AP outsourcing resource are following internal protocols for working with vendors. 

To alleviate data security concerns, it's suggested to conduct routine audits, insist on regular security updates, and insist on stringent data breach protocols to be in place.

9. You may create more work than you started with

We’ve all been there. You hire an agency that promised the world, but they fail to deliver on that vision for one reason or another. 

AP sourcing is no different. This is why it’s essential for you to do reference checks before you onboard an AP service provider and work closely with your third-party support to ensure your goals are being met. 

10. Third-party agencies may lack contextual understanding

An AP outsourcing provider might lack the situational nuances and understanding that in-house AP specialists possess. 

This inherent lack of contextual knowledge can potentially limit their ability to successfully handle intricate financial procedures and anomalies, which could negatively impact the efficiency and accuracy of AP operations.

This is why businesses often lean more on full-time staff as they scale. 

AP automation software vs. AP outsourcing

AP automation software digitizes and automates the end-to-end accounts payable process, allowing businesses to capture, code, match, and approve accounts payable data using fewer manual tasks.

As mentioned previously, AP outsourcing service providers often use AP automation software to support businesses they work with.

However, there are AP automation solutions that in-house finance teams can use to automate the end-to-end accounts payable process without having to lean on AP outsourcing firms. 

With solutions like Rho, lean finance teams – from a sole CFO or business owner to a small team – can easily process thousands of invoices in seconds.

In a few clicks, you can: 

  • Collect invoices and supporting documentation within one platform
  • Use AI-powered OCR invoice scanning to eliminate manual data entry
  • Receive all documents and approval notifications within the software
  • Pay bills in bulk or one-by-one across different payment methods: ACH, wire, check, or card
  • Sync data seamlessly with your ERP for month-end close
