Sending a $20,000 invoice and watching $600 disappear into card fees is a specific kind of pain that contractors, consultants, and service businesses know well. The fix is not complicated: give customers a way to pay by bank transfer, keep the fee at 0.9%, and let it cap at $1,000 no matter how large the ticket gets. That is exactly how ACH works on invoices we send through Pocket Boss, and the savings on a single job can cover months of software overhead.
What ACH Actually Is on an Invoice
ACH stands for Automated Clearing House, the network that moves money directly between bank accounts in the United States. When a customer pays an invoice by ACH, they enter their routing and account number — or authorize a saved bank account — and the funds transfer electronically, usually settling in one to two business days.
From the customer's side it feels like paying a bill online. From your side it means the payment lands in your account without a card network touching it, which is why the cost structure is completely different from credit or debit cards.
On invoices sent through Pocket Boss, our ACH pricing is straightforward: 0.9% of the transaction amount, or $0.50, whichever is greater, with a hard cap of $1,000 per transfer. That cap is the number that changes everything on large tickets.
Why Card Fees Hurt More as Tickets Get Bigger
Card processing fees are a percentage of every dollar. That relationship is linear and unforgiving. A typical effective rate for a small business accepting a mix of rewards cards, corporate cards, and premium travel cards often lands between 2.5% and 3.5% when interchange, assessments, and processor margin are all counted together.
On small tickets that percentage is a rounding error. On large tickets it becomes a line item that rivals labor cost.
Here is the math on two common invoice sizes, using 3.0% as a typical illustrative card rate and our 0.9% ACH rate:
| Invoice Amount | Card Fee at 3.0% | ACH Fee at 0.9% | You Keep Extra |
|---|---|---|---|
| $5,000 | $150 | $45 | $105 |
| $10,000 | $300 | $90 | $210 |
| $20,000 | $600 | $180 | $420 |
| $50,000 | $1,500 | $450 | $1,050 |
| $112,000 | $3,360 | $1,000 (cap) | $2,360 |
At $112,000 the ACH fee stops growing entirely. Every dollar above that threshold is free to process. For businesses that invoice large project amounts — roofing, remodeling, IT projects, consulting retainers, equipment sales — the cap alone can represent thousands of dollars per year in recovered margin.
These figures are illustrative. Your actual card rate depends on your card mix and pricing model, which a statement review will confirm.
How Does the Cap Work in Practice?
The cap is not a promotional rate or a volume tier you have to qualify for. It is simply the ceiling on what we charge per ACH transfer. Once the fee calculation hits $1,000, it stops.
If a customer pays a $150,000 invoice by ACH, the fee is $1,000. If they pay a $500,000 invoice by ACH, the fee is still $1,000. For businesses that occasionally handle very large single payments — a commercial contractor billing a general contractor, a staffing agency billing a corporate client, a consultant closing a large engagement — this is a meaningful structural advantage over any percentage-only pricing model.
For context, that same $150,000 payment on a card at 3.0% would cost $4,500. The difference is $3,500 on a single transaction.
What Does This Look Like on a Real Invoice?
Pocket Boss invoices include a payment link. When we set up your account, we configure which payment methods appear on that link. If you want to offer both card and ACH, both options show up and the customer chooses. If you want to nudge customers toward ACH on large invoices, we can set thresholds or simply make ACH the default for invoices above a certain amount.
The customer clicks pay, selects bank transfer, enters or confirms their bank details, and authorizes the payment. You get a notification. The funds settle in one to two business days. No manual reconciliation, no chasing checks, no waiting for a mailed payment.
Because invoicing lives inside Pocket Boss alongside your CRM, scheduling, and automation tools, the payment status updates the job record automatically. A paid invoice can trigger a follow-up text, a review request, or a task for your team — without anyone touching it.
Isn't ACH Slower Than a Card?
One to two business days is slower than the instant authorization a card provides, but it is faster than a mailed check, and for most invoice-based businesses the settlement timeline is not the bottleneck. The bottleneck is getting the customer to pay at all.
A payment link in a text message or email, with a clear bank transfer option, converts faster than an invoice that requires the customer to write and mail a check. The net effect for most businesses is that ACH invoices get paid sooner than paper-based alternatives, even accounting for the settlement window.
For businesses that need faster access to funds, our team can walk through what options make sense for your volume and ticket size during a statement review.
How ACH Compares to What You Might Already Be Using
Square, Stripe, and PayPal all offer ACH or bank transfer options, but their fee structures differ. Stripe's ACH fee has historically been 0.8% capped at $5. PayPal's bank transfer pricing varies by product. Square's ACH offering is more limited. None of these platforms are designed around the needs of invoice-heavy service businesses the way Pocket Boss is, and none of them bundle ACH payment collection with CRM, scheduling, texting, and automation in a single subscription.
The comparison that matters most is not ACH provider versus ACH provider. It is the total cost of your current setup — card fees plus software subscriptions plus admin time — versus a single platform that handles all of it at lower cost.
The chart below shows illustrative effective processing costs for a business with a mix of card and ACH payments. Numbers are illustrative and vary by business type and card mix.
Which Businesses Benefit Most?
ACH on invoices delivers the clearest savings for businesses where average tickets are high and customers are other businesses or financially sophisticated consumers who are comfortable with bank transfers. The strongest fits include:
- Contractors, remodelers, and specialty trades billing project amounts of $5,000 or more
- Consulting firms, agencies, and professional services billing retainers or project fees
- Equipment dealers, distributors, and B2B sellers with large order values
Businesses with low average tickets — under $500 — will see smaller absolute savings from ACH, though the percentage savings are identical. For those businesses, the bigger opportunity is usually optimizing card interchange categories, which is a separate conversation our team can walk through.
What to Do Next
If you process invoices regularly and want to see exactly what ACH would have saved you over the last 90 days, the fastest path is a statement review. We look at your current fees, your ticket distribution, and your card mix, and we show you the actual dollar difference — not an estimate based on averages.
