Card vs ACH vs Check: What Each Invoice Payment Really Costs Wholesale Distributors

Why the payment mix matters more for wholesale distributors

A distributor's receivables profile looks very different from a store's. Invoices are typically larger and less frequent, most payments come in card-not-present (by phone, emailed invoice, or customer portal), and card-present sales are usually limited to will-call counters or showroom pickups. Many accounts still pay by paper check on net 30 or net 60 terms, which means the real cost of a check is not the stamp or the bank deposit. It is the days of float plus the time someone in AR spends opening mail, keying remittances, and chasing short-pays.

Card payments flip that equation. Cash arrives in days, but the processing fee scales with the invoice size, so a single large card payment can cost far more in fees than a check. ACH usually sits in the middle: a low per-payment fee, little handling time, but customers still tend to pay on their terms date rather than early. This tool puts all three on the same scale, including the carrying cost of cash you are waiting on, so you can see which trade-off actually costs your business more.

Seasonality is worth factoring in. Many distributors see inventory build-ups ahead of their customers' busy seasons, which can stretch cash just as receivables balloon. If your volume swings, run the tool for a typical month and again for your peak month. The cash tied up in collection number tends to matter most when you are paying suppliers for the next season's stock.

Worked example: a hypothetical wholesale distributor

These numbers are entirely hypothetical and use assumptions, not benchmarks. Picture a distributor invoicing $400,000 a month with a $2,500 average invoice, or 160 invoices. Customers pay 15% by card, 35% by ACH, and 50% by check. Assumed days to cash: card 5, ACH 32, check 48. Card rate left blank, so the tool uses the B2B default estimate of 2.8%. Assumed ACH fee $0.50, check cost $4.00, staff cost $35 per hour, 12 staff minutes per check and 3 per ACH or card payment, and an annual cost of cash of 9%.

Under those assumptions, card costs about $1,722 a month in fees and staff time but only $75 in carrying cost. ACH costs about $126 direct plus $1,120 carrying cost. Checks cost about $880 direct (roughly $11 per invoice) plus $2,400 carrying cost on $320,000 waiting in the mail and in AR. Total: about $6,323 a month, around 1.58% of volume, with roughly $479,333 tied up in collection and a weighted 35.95 days to cash.

Now move half of the check volume to ACH using the scenario slider. Total monthly cost drops to about $5,573, a saving of roughly $750 a month, cash tied up falls by about $53,333, and weighted days to cash drops to 31.95. Moving the same checks to card instead would shorten days to cash further but, at a 2.8% card rate on $2,500 invoices, would raise total cost in this example. The answer changes if your cost of cash is high, your check terms are long, or your actual card rate is lower than the default.

Estimates are based on published industry averages and are not a quote. Actual rates depend on card mix, ticket size, industry, and underwriting.

What wholesale distributors should watch for in their card costs

Many B2B card payments are made on commercial, corporate, or purchasing cards, which often carry higher interchange than consumer cards. On large tickets, passing Level 2 and Level 3 data (such as tax amount, PO number, and line-item detail) can qualify some commercial card transactions for lower interchange, but only if your gateway or virtual terminal sends that data. If your average invoice is $1,000 or more, the full report adds a section on the questions to ask about large-ticket card pricing.

Look at your statement for fees that are easy to miss: monthly minimums, statement and batch fees, PCI non-compliance fees, annual fees, and on tiered pricing, non-qualified surcharges that frequently land on commercial cards keyed over the phone. Enter your true effective rate (total fees divided by card volume) rather than the advertised rate. The tool marks whether it used your rate or the default estimate, and the gated report compares your current card cost with an illustrative interchange-plus estimate built on placeholder pricing assumptions, not TouchSuite's actual rates.

Some distributors consider surcharging or offering a cash discount to offset card fees on large invoices. Rules vary by card brand and by state, so confirm the requirements with the card brands and your state before changing how you price card payments.

What a good result looks like for a wholesale distributor

There is no single right mix. For most distributors, a strong result is a lower check share, a shorter weighted days to cash, and a clear view of which customers should be nudged to ACH versus allowed to pay by card. If checks are 30% or more of your volume, the full report emphasizes an ACH/eCheck and virtual terminal setup checklist, including remittance capture so payments match invoices without manual keying.

Factor in the operational realities that hit distributors specifically: partial payments, deductions for returns and damaged goods, credit memos, and early-pay discounts like 2/10 net 30. A customer who takes a discount and pays by card early may still be cheaper than one who pays by check on day 50. If weighted days to cash reaches 30 or more, or checks take 45 days or longer, the report links to the Merchant Funding Payback Estimator so you can compare the cost of waiting with the cost of working capital.
