Card vs ACH vs Check: Invoice Payment Cost Comparison for Contractors and Home Services

How contractors and home service businesses actually get paid

Most contractors and home service companies run two businesses in one payment-wise. Residential work, like a water heater swap, a roof repair, or a quarterly pest service, is usually paid by a homeowner using a card or a personal check, often at the job site or from an emailed invoice. Commercial and subcontract work is usually paid by a general contractor, property manager, or facilities team by check or ACH, often on net-30 or longer terms and sometimes with retainage held back.

That split shapes your inputs. Ticket sizes in this trade are large compared with retail. A service call might be a few hundred dollars, while a replacement, remodel, or progress draw can run into the thousands. If your average invoice is $1,000 or more, the tool flags you for large-ticket card pricing questions in the full report, because a percentage fee on a $9,000 job is a real number.

Card-present versus card-not-present matters too. A card tapped or dipped on a mobile reader in the driveway is generally priced differently than a card number typed into an invoice link or virtual terminal back at the office. If your techs collect on site, your effective rate may differ from a company that bills everything by email. If you know your current rate, enter it. If you leave it blank, the tool uses a placeholder industry average for the business type you choose, labeled as an assumption.

Choosing a business type: if you mostly bill homeowners, Professional services is usually the closer fit. If you mostly bill general contractors, builders, or commercial accounts, B2B is usually closer. Neither is exact for the trades, so entering your own card rate from a recent statement gives you a more useful result.

Worked example: a hypothetical HVAC and plumbing contractor

All numbers here are hypothetical and chosen for illustration. Picture a contractor invoicing $120,000 a month with a $2,400 average invoice, which works out to 50 invoices. Thirty percent of dollars come in by card, 20% by ACH, and 50% by check. Days to cash: card 3, ACH 5, check 35. Card rate left blank with Professional services selected, so the tool applies the 2.9% placeholder. ACH costs $0.50 per payment, each check costs $3 out of pocket (assumed for deposit runs, bank fees, and postage on reminders), and office staff cost $30 an hour, spending 10 minutes per check, 3 per ACH payment, and 2 per card payment. Cost of cash is set at 10% a year.

Baseline result: about $1,279 a month in direct costs (card fees of $1,044 are most of that), plus about $647 a month in carrying cost on roughly $77,600 sitting in collection, for a total near $1,926 a month, or about 1.6% of revenue. Weighted days to cash: 19.4. Notice that checks look cheap on fees, at $75, but the $70,000 tied up in check float creates most of the carrying cost.

Now the scenario slider. Moving half of the check share to ACH (check drops to 25%, ACH rises to 45%) brings the total to about $1,601 a month. That is roughly $325 a month in savings, about $30,000 in cash freed up, and weighted days to cash falling to 11.9. Moving that same half of check volume to card instead frees slightly more cash, about $32,000, but card fees rise enough that the month comes out about $516 more expensive. The tool labels that an additional cost, not a saving.

The takeaway for this hypothetical shop: ACH is the cheaper lever for big commercial invoices, while card earns its fee where speed matters most, such as material deposits or jobs where waiting a month for a check would squeeze payroll. Estimates are based on published industry averages and are not a quote. Actual rates depend on card mix, ticket size, industry, and underwriting.

Deposits, progress billing, and maintenance plans in home services

Deposits: many contractors collect an upfront payment before ordering equipment or materials. Because the deposit funds a purchase you have to make right away, days to cash on that money matters more than on a final payment. If you take deposits by card, consider modeling a higher card share and see whether the faster cash offsets the fee for your business.

Progress billing and retainage: on longer jobs, each draw is its own invoice, so your invoice count goes up and your average invoice goes down compared with billing once at completion. Retainage held by a general contractor until closeout can stretch real days to cash well past your stated terms. Use the days you actually experience, not the days on your contract. If check days hit 45 or more, the tool points you to the Merchant Funding Payback Estimator so you can weigh the cost of bridging that gap.

Maintenance agreements and recurring service: HVAC tune-up plans, lawn and pest programs, pool service, and cleaning contracts are a natural fit for recurring ACH or card-on-file billing. They are small, predictable invoices that cost far more in office minutes when they arrive as paper checks. If a large share of your invoice count is recurring, test moving those check payers to ACH.

Seasonality: HVAC peaks in summer and winter, roofing follows storm season, and landscaping and exterior work cluster in spring and fall. Run the tool twice, once with a peak month and once with a slow month. Cash tied up in collection during peak season is often the money you need for extra crews and inventory, and the carrying cost line shows what that float is worth to you.

Fees and fine print contractors and home service pros should check

When you pull a statement to find your real card rate, divide total fees by total card volume. Then look for line items that often go unnoticed: PCI non-compliance fees, monthly statement or minimum fees, annual fees, higher-priced tiers applied to keyed-in or invoice-link payments, equipment leases on readers you could own outright, and early termination fees. These do not show up in the advertised rate but do show up in your effective rate.

Refunds and disputes behave differently in this trade. Deposits on canceled jobs may need to be refunded, and disputes tend to center on workmanship or scope rather than non-delivery. Signed estimates, change orders in writing, and completion photos tied to the invoice make a dispute easier to respond to, regardless of which payment method the customer used.

A good result for a contractor or home service business is usually not the lowest fee line. It is a mix where weighted days to cash drops, cash tied up in collection shrinks to something your line of credit or reserves can comfortably cover, and office time spent chasing and depositing checks goes down. For many shops that looks like ACH for commercial and recurring accounts, card for deposits and on-site residential collections, and checks as the exception.

The full report, available after a short form, runs four recommended mix scenarios against your baseline, includes an ACH, eCheck, and virtual terminal setup checklist if checks are 30% or more of your volume, covers Level 2 and Level 3 card data questions for large-ticket invoices, and shows an illustrative interchange-plus card estimate using placeholder pricing assumptions, not a quote and not TouchSuite's actual rates.
