The Silent Killers of Accounts Payable: 3 Outsourcing Errors That Cost You Money

By a B2B payments industry contributor.
A single returned check might seem like a small problem. You find the right address, fix your records, and send the payment again. But these small problems are signs of a bigger, more costly issue in how you pay your bills. Every manual fix, late payment, and hour spent stuffing envelopes wastes your team’s time and your company’s money. The real cost isn’t just the price of a stamp. It’s the important work your team could be doing instead.
Many businesses use third-party payment services to get away from these manual tasks. Solutions like SmartPayables can handle the whole process, from printing and mailing checks to sending digital payments. But just handing off the work isn’t a perfect fix. Switching to an outside service has its own risks that can be just as costly as the problems you were trying to solve. The key is to understand these new risks.
The move to digital payments is happening fast. According to Nacha, the group that manages the ACH network, the number of businesses using standard ACH payments grew from 48% in 2023 to 60% in 2024. The use of Same Day ACH grew in a similar way, from 45% to 56% in that time. This quick change shows why it’s so important for businesses to get their payment plans right, for both paper and digital payments.
Quick answer: Using an outside service for business payments can cut down on office work, but common mistakes with data, security, and software can quickly cancel out the benefits. To avoid these problems, you should treat payment outsourcing as a smart update to your system, not just a simple handoff of tasks.

How Much Do ‘Small’ Data Errors Really Cost?
Small data mistakes, like a wrong address or an old bank account number, cause a chain reaction of costs and slowdowns. Hiring an outside service can’t fix this by itself. The problem isn’t the service you hire; it’s the quality of the information you give them. A payment service is like a powerful engine, but it needs good fuel from you to run.
The most obvious costs are failed payments. For paper checks, this means returned mail, the cost of new postage and checks, and any fees your provider charges to send it again. For digital payments, a typo in an account number can cause the payment to fail, lead to a return fee from the bank, and hurt your relationship with a supplier. These small costs add up fast when you make hundreds or thousands of payments.
The quick move to digital payments makes clean data even more important. According to Nacha, the group in charge of the ACH network, 60% of businesses now use standard ACH for payments, which is a big jump from last year. Even more telling is the use of faster payments, with 56% of businesses now using Same Day ACH. These systems are faster, but they don’t handle mistakes as well. A bad address on a check might delay it by a week. A bad account number on a Same Day ACH transfer can cause a much harder problem to fix quickly.
❝ The real cost of one payment error is rarely just the postage or bank fee. Any payment problem that needs a person to fix it takes real staff time to track down, correct, and resend. For someone on your payments team, that single error can easily cost more in labor than it does in fees.
The solution starts before you send a payment file. You need a process to clean your data regularly. Before you hire a service, ask them about their tools for checking data. Do they offer CASS-certified address checks to match addresses with the USPS database? Do they have systems to spot bad bank routing numbers? A good partner doesn’t just process what you send; they help you make sure it’s correct first.
Are We Overlooking Critical Security and Compliance Features?
When you look at a payment service, you need to go past their ads and check their real security and safety rules. A provider’s website might list awards or certificates, but you have to check if their claims are true. This means asking for their official reports and understanding what they mean for your company’s safety.
The most important document to ask for is a System and Organization Controls (SOC) report. A SOC 2 Type 2 report is a deep check by an outside company to prove the provider’s systems for security, privacy, and other controls are working over time. The American Institute of Certified Public Accountants (AICPA), which sets the standards for these reports, says they are made to help you trust a service’s security. Don’t just trust a logo on a website; ask for a copy of the latest report.
❝ When you review a SOC report, look for the auditor’s opinion. Look for any “exceptions” they list. These are times when the provider’s controls didn’t work as planned. A few small exceptions might be okay, but a lot of them could be a big warning sign.
Besides general security, think about rules for your specific industry. If you handle healthcare payments, your provider must be HIPAA compliant. This isn’t just a box to check; it means they have specific ways to protect health information. Ask a potential partner to explain how they handle documents with this private data. Also, if you process credit cards, PCI DSS (Payment Card Industry Data Security Standard) compliance is a must.
Finally, ask about tools to fight fraud. One of the best is Positive Pay. With this service, your company sends a file of all your checks to your bank each day. The bank will only pay for checks that match the details in that file. This helps stop fake or changed checks from being cashed. A good payment service should be able to create and send these files to your bank for you automatically.
Is Our Vendor’s Platform Flexible Enough for Our Workflow?
A service’s system might be good at standard payments, but its real value shows when it handles your company’s unique needs. Many businesses make the mistake of only looking at the cost per check or bank transfer. They forget about the hidden costs of a system that is hard to use and doesn’t connect well with their accounting software.
The key difference between a basic service and a true partner is automation, usually through an Application Programming Interface, or API. An API is a tool that lets your accounting software talk directly to the payment provider’s system. This means your team doesn’t have to manually export payment data, reformat it, and upload it to the vendor’s website. That manual process is slow and often leads to mistakes.

Without a good API, the time you “save” from outsourcing the mailroom is lost to new, boring data tasks. Your team ends up spending hours preparing data that a proper connection would handle in seconds. This is like moving a problem instead of solving it. The goal is to reduce the total amount of manual work, not just change what kind of manual work is done.
❝ Ask a potential vendor if their API supports webhooks. A webhook is an automatic message sent from their system to yours when something happens, like a check being cashed. This is much better than your system having to constantly ask their system for updates. It gives you real-time information to better manage your cash and records.
A flexible system should also fit your company’s special needs. For example, can you add custom notes to payments for your own reports? Can you set up approval steps that match your current company rules? If the vendor says you have to change how you work to fit their system, it’s not a real solution. It’s a tool that will create new work for your team.
Frequently Asked Questions
What is the difference between a payment outsourcer and my bank’s bill pay service? Your bank’s bill pay is good for a small number of payments, but a special payment service is built for complex business needs. They usually offer better connections to your accounting software, handle special documents like HIPAA-compliant forms, and provide fraud prevention services like Positive Pay that banks don’t always offer.
Why would I receive a check from a third-party I don’t recognize? This is common when a company you work with hires a service to handle their payments. The company that owes you money is still the one paying you, and the money comes from their account. The payment service’s name might be on the envelope because they are the ones printing and mailing the check on that company’s behalf.
What does a typical pricing structure for these services look like? Most services charge a one-time setup fee to get your account ready. After that, you usually pay a fee for each check printed or digital payment sent, plus the cost of postage for mailed items. Prices are often tiered, so the cost per item usually goes down as you send more payments.
What types of businesses benefit most from outsourcing payments? Any business that sends a lot of payments can benefit, but it’s especially helpful for certain industries. Property management companies, healthcare providers sending patient refunds, and law firms sending out settlement checks all use these services to handle complex payments and follow the rules.
How long does it take to get started with a payment outsourcing service? It depends on how connected you want to be. If you plan to upload payment files on their website, you can often be set up in a few days. A full API connection that links directly to your accounting system is a bigger project that can take several weeks, depending on when your tech team is available.
The Real Goal: A More Resilient Payment Process
Moving your payments to an outside service is more than just a way to save money. The biggest mistakes happen when you see it as just a mail service instead of part of your company’s financial system. The goal isn’t just to stop stuffing envelopes. It’s to have fewer payment problems, improve security, and free your team from fixing mistakes. Real success means your team spends less time on manual work, not just that you pay less for each check.
The key decision is not about comparing features, but about choosing a partner that makes your own processes stronger. A basic service takes the file you give them and processes it. A real partner helps you improve that file before it’s even sent, using tools to check and clean the data. They connect with your systems to get rid of manual data entry and give you real-time updates that make it easier to track your money.
In the end, you should judge a provider on how they handle problems when they happen. A perfect payment is easy. The real test is what happens when an address is wrong, a bank account is bad, or a security threat appears. A system’s strength is shown in how it deals with failure. Choosing a partner who prepares for those moments is how you go from just outsourcing a task to truly upgrading a key part of your business.
