ACH Payments for Contractors: Lower Fees, Faster Deposits

Every time a client pays a $15,000 invoice with a credit card, you lose $465 or more to processing fees. That is real money. Enough to cover a day of labor or a load of materials.

ACH payments are the alternative most contractors overlook. They pull funds directly from the client's bank account, skip the card networks entirely, and cost a fraction of what credit cards charge. For contractors handling invoices in the thousands or tens of thousands, the savings add up fast.

This guide covers how ACH payments work, what they cost, and how to start offering them to your clients.

What Are ACH Payments?

ACH stands for Automated Clearing House. It is the electronic network that processes bank-to-bank transfers in the United States. When your paycheck hits your bank account via direct deposit, that is an ACH transfer. When you pay a bill online using your bank account number and routing number, that is also ACH.

For contractors, ACH payments mean the client authorizes a transfer directly from their bank account to yours. No credit card network in the middle. No interchange fees. No card brand markups.

ACH handles over 30 billion transactions per year in the U.S. It is not new technology. But it has only recently become easy for small contractors to offer, thanks to payment platforms that handle the complexity behind the scenes.

ACH vs. Credit Card Fees: The Real Difference

Processing fees on credit card payments typically run 2.9% to 3.5% plus a per-transaction fee of $0.30. ACH fees are significantly lower, usually between 1.0% and 1.8%.

Look at what that means on real invoices:

On a $25,000 roofing job, ACH saves you $375. Process ten jobs like that per year and you have saved $3,750 in fees alone. That is a meaningful number for any contractor.

The savings get even better with platforms that offer tiered ACH rates. Linkster's Business and Enterprise plans charge just 1.0% on ACH, which drops that $25,000 fee to $250. That is $500 less than a standard credit card rate.

How Long Do ACH Payments Take?

This is the one trade-off with ACH. Credit card payments settle in 1 to 2 business days. ACH payments take longer.

Standard ACH settlement: 3 to 5 business days from the time the client authorizes the payment to when the funds are available in your account.

Same-day ACH: Some platforms offer same-day ACH processing, which reduces settlement to 1 to 2 business days. There is usually an additional fee for this service.

Here is the typical timeline:

For most contractors, the 3 to 5 day settlement is perfectly acceptable. You are not waiting 30 to 60 days for a check. You are waiting less than a week, and the payment is guaranteed once it clears. No bounced checks, no "the check is in the mail."

Pros and Cons of ACH for Contractors

Pros

• Lower fees. Save 1 to 2 percentage points compared to credit cards on every transaction.
• Good for large invoices. The bigger the invoice, the more you save. On a $50,000 contract, the difference between 3% and 1.5% is $750.
• No chargebacks. Credit card payments can be disputed and reversed (chargebacks). ACH payments have a much narrower dispute window and are far less susceptible to fraudulent chargebacks.
• Predictable costs. ACH fees are straightforward: a flat percentage with no per-transaction fee on most platforms.
• Professional appearance. Offering bank transfer as a payment option signals to clients that you are a serious business, not just someone with a Venmo handle.

Cons

• Slower settlement. 3 to 5 business days versus 1 to 2 for credit cards. If you need money tomorrow, ACH is not the fastest option.
• Client friction. Some clients are less comfortable entering bank account details online. They are used to credit cards and may hesitate at first.
• No rewards for clients. Clients cannot earn credit card points on ACH payments. For a $15,000 invoice, that is real rewards money some clients do not want to give up.
• Return risk. ACH payments can be returned for insufficient funds, though this is less common than bounced checks.

For most contractors, the pros outweigh the cons, especially on invoices over $5,000 where the fee savings become substantial.

How to Offer ACH Payments to Your Clients

Setting up ACH is straightforward with a modern invoicing platform. You need three things:

1. Use a Platform That Supports ACH

Not every invoicing tool offers ACH. Generic tools like PayPal and Venmo do not support ACH for invoice payments. You need a platform built on a payment infrastructure like Stripe that supports both card and bank transfer payments.

Linkster includes ACH on every plan. When you send an invoice, the client sees both payment options (card and bank transfer) and chooses the one they prefer. There is nothing extra to set up on your end.

2. Set Up Your Bank Account

You will need to connect your business bank account to your payment platform. This is where your funds will be deposited. The setup typically involves:

• Entering your bank account number and routing number
• Verifying the account with micro-deposits (two small test transactions)
• Confirming your business identity

This takes about 10 minutes and only needs to be done once.

3. Present Both Options on Every Invoice

When you send an invoice, make sure the client can see both payment methods. Do not hide ACH behind a menu or make them ask for it. The payment selection should be front and center.

A simple note on your invoice can encourage ACH: "Pay by bank transfer to avoid credit card processing fees." This frames it as a benefit to the client, not just a cost savings for you.

4. Educate Your Clients

Some homeowners have never paid an invoice via bank transfer. A brief explanation goes a long way:

• "Bank transfer works just like paying a bill online through your bank."
• "You enter your account and routing number. The funds transfer directly."
• "It is the same system your employer uses for direct deposit."

Most clients are comfortable once they understand it is the same technology they already use for other payments.

When to Recommend ACH vs. Credit Cards

Not every payment should go through ACH. A quick guide:

The sweet spot for ACH is invoices in the $5,000 to $50,000 range, which is exactly where most contractors operate. A plumber billing $8,000 for a bathroom rough-in, an electrician invoicing $12,000 for a panel upgrade, or a GC collecting a $20,000 progress payment all save meaningfully with ACH.

Keep More of What You Earn

ACH payments are one of the simplest ways to reduce your costs as a contractor. The fees are lower, the process is simple, and the technology is proven. The only trade-off is slightly longer settlement times, which is a small price to pay for saving hundreds or thousands of dollars per year in processing fees.

Start by choosing an invoicing platform that supports both ACH and credit card payments. Present both options on every invoice. Let your clients choose, and watch your processing costs drop.

For contractors processing $10,000 or more per month in payments, ACH is not a nice-to-have. It is a smart business decision that puts more money in your pocket on every job.
