- Choose an ACH provider that fits your transaction volume, since fees add up as you scale.
- Compare providers on cost, payment options, accounting integration, and approval workflows before you commit.
- Use ACH to cut payment costs, as transfers typically cost less than $1.50 each versus $25 to $30 for a domestic wire.
- Recognize that standard ACH settles in one to two business days, with same-day options when speed matters.
What are B2B ACH transfers?
ACH payments are a way to transfer funds electronically from one bank account to another through the Automated Clearing House network, which includes the Federal Reserve and is managed by the National Automated Clearing House Association (NACHA).
Businesses can use ACH to make B2B payments to each other even if their accounts are at different banks.
- The funds move from the payor’s bank to an automated clearing house network.
- Once the clearing house approves the transaction, the funds are then deposited into the recipient’s bank account.
But how do ACH services for small businesses make your life easier?
In 2025, the ACH Network processed 35.2 billion payments valued at $93 trillion, including 8.1 billion business-to-business payments, making it the backbone of US business payments.
How does ACH payment processing work?
ACH payment processing moves money electronically between bank accounts through the Automated Clearing House network. It works by grouping transfers into batches and settling them between banks.
Here is how a typical ACH payment moves from start to finish:
- You authorize the payment and share the recipient’s bank details, or they share yours.
- Your bank or payment provider submits the payment instruction to the ACH Network.
- The network sorts and routes the instruction to the recipient’s bank.
- The banks settle the transfer and the funds land in the recipient’s account.
Because payments travel in batches rather than one by one, ACH keeps costs low. Standard transfers usually clear within a couple of business days, and same-day options are available when you need funds to move faster.
Benefits of ACH payments for SMBs
Businesses use ACH payments to get various benefits that support their financial operations and growth.
Reduce costs
ACH payments typically cost less than $1.50 per transaction, far cheaper than paper checks or wire transfers, which usually run $25 to $30 for a domestic wire.
Increase efficiency of financial operations
Every payment is easily recorded, tracked and reconciled. If you use a good tool, it’s also easily shareable with your accountant or bookkeeper. Plus, instead of writing and sending checks manually, you just click a few buttons and you’re done.
Payments can even be scheduled in advance, so you can work in bulk instead of jumping from task to task.
Protect your business – and the environment
Safety is key when it comes to business payments. ACH payments are transferred through a clearing house, which has to comply with regulations and laws. The process enables businesses to get their money back within two months if fraud occurs.
Meanwhile, businesses are doing all this electronically, protecting the environment from producing and discarding more paper and ink.
What to look for in an ACH provider
Remember to account for these considerations when managing your small business’ ACH processing operations.
The cost of ACH payments
Some financial institutions and most service providers charge fees for ACH transactions. Fees vary, depending on the bank or service provider, whether you’re on the sending or receiving end, and if you need to make an expedited payment.
- Many banks charge a small per-transaction fee. If you’re only making a couple of transactions a month, the fees are less significant, but as the transaction volume increases, they add up.
- Some service providers charge subscription fees, which can add to your monthly costs, so that’s also something to consider.
- Fast transactions can be expensive. Standard ACH payments normally take one to two business days to process. If you need to expedite your payment and use a same- or next–day ACH, banks and certain service providers may charge a flat fee per transaction, regardless of the amount. Others may charge a percentage of the transaction.
When it comes to fees, the differences between service providers can amount to hundreds, even thousands, of dollars a year, depending on your transaction volume. Make sure to compare the different service costs before making your decision.
Just putting it out there: Melio includes up to five free ACH payments a month on its free plan, with paid plans offering more free ACH, unlike some competitors such as Plastiq and Bill. Check Melio’s pricing page for current fees and same-day options.
Additional payment options
Some vendors still insist on getting paid by check. Maintaining two separate payment procedures – paying some vendors with ACH and others by paper checks – is a logistical and accounting challenge.
So, what can you do?
- If your bank is your service provider, you probably can’t merge the two tracks.
- Most ACH service providers will limit you to ACH only.
- However, there are service providers that offer more payment options, including decoupling the payment track from the way vendors receive funds. These services allow you to pay with ACH, and your vendors can receive a paper check.
Effective integration with your accounting software
One of the biggest advantages of ACH payments is that they’re digitally recorded with all the relevant financial information.
There’s no reason businesses should waste time registering that information a second time in QuickBooks (or another accounting software they use) – especially since there are ACH services for small business operations that offer seamless integration with leading accounting software tools.
Effective user interface and approval workflow designed for businesses
Business owners often have more than one individual involved in the payment process: it could be an accountant, bookkeeper, or a member of your team.
As a business grows and changes, additional users and approval levels could be added. Businesses need to make it simple for them to access and manage the payments, while still giving management the oversight and control over these team members’ actions.
Hopefully, businesses can add all that to their workflow at no extra cost, but even getting a good interface isn’t always a piece of cake.
- Bank interfaces don’t usually provide this functionality.
- Some service providers that offer approval levels are far too complicated, because they have designed their interfaces with large organizations in mind. They also charge fees for every additional user.
Small businesses need solutions that were developed with them in mind – those that offer the right balance between simplicity and control, preferably with no added cost.
