Payment USA publishes this merchant guide. Examples are illustrative; your agreement, account configuration and applicable requirements determine your actual costs and options.
01 / Find the four parts
What each section tells you.
Processors use different labels and orders. A useful review follows the money from transactions to the bank, then traces each charge. Collect every page, including notices and fee-detail attachments.

| Area | What it shows | Your check |
|---|---|---|
| Sales and credits | Submitted sales by card brand or channel; refunds and other credits. | Confirm the period and whether Amex is included. Gross sales are not deposits. |
| Funding / deposits | Batches, deductions, holds and bank transfers. | Match transfer dates and amounts to your bank; explain timing differences. |
| Processing detail | Interchange or tier charges, network assessments, processor percentage and per-item charges. | Separate pass-through costs from processor pricing when the statement permits. |
| Other charges and notices | Monthly services, equipment, PCI-related items, disputes, annual charges and changed terms. | Identify the fee owner, contractual basis and recurrence. |
Gross sales are submitted purchases before refunds. Net sales subtract credits such as refunds; a statement may show chargebacks and adjustments separately. Deposits are cash transfers, so they can be lower than net sales after withheld fees or reserves. A processor that bills fees monthly can transfer deposits before those fees are debited. Follow the actual arithmetic rather than relying on a heading alone.
Do not compare one day's bank transfer with a calendar month's sales without allowing for weekends, cutoffs and batches settling later. An unmatched amount is a question to investigate, not proof of overcharging.
From Payment USA's statement reviews
First, make the statement understandable.
In our work with merchants, confusion often starts before the rate comparison. An owner sees a low quoted percentage or a line called “discount” and reasonably assumes it means something different from what the statement actually charges.
“Discount” can mean a charge.
On a processing statement, a discount rate generally describes a processing charge, not money saved. Daily discount usually means processing charges are withheld as transactions settle; monthly discount generally means those charges are collected monthly. Other fees may still be billed separately. Check the funding detail and agreement for the exact timing.
Check for a separate Amex bill.
We also encounter merchants whose Amex fees arrive separately. If the processor statement includes Amex sales but leaves out those fees, the apparent all-card effective rate can look lower than the complete cost. We explain the separate charges before comparing rates.
A quoted markup is not the full rate.
AutoTech, an automotive business we helped, believed it was paying 0.5%. Our statement review found a 3.25% effective rate, and Payment USA subsequently brought that effective rate to 2.8%. The initial 0.5% figure represented markup, not the entire cost of acceptance. See the AutoTech cost comparison and its assumptions.
Our review separates underlying card costs, processor markup and additional fees, then explains what each charge covers and which charges merit a question. The goal is for the merchant to understand what they are paying and why. Payment USA never charges a cancellation fee on any account we offer.
Practice notes and the AutoTech account were supplied by Payment USA in September 2026. The customer example describes one account; it is not a promised rate or a typical savings claim.
02 / Follow the dollars
A fictional statement, reconciled.
All numbers below are invented for teaching. They are not customer data, a typical rate or a Payment USA offer. Assume one July statement, all cards billed by one processor, and fees withheld from funding.
Swipe across to read the arithmetic.
| Line | July amount | Meaning |
|---|---|---|
| Gross Visa / Mastercard / Discover sales | $40,000 | Submitted purchases. |
| Gross Amex sales | $10,000 | Included in this processor's fee scope. |
| Total gross card sales | $50,000 | $40,000 + $10,000. |
| Refunds | −$500 | Customer credits, not processing charges. |
| Net card sales | $49,500 | $50,000 − $500. |
| Processing and account fees | −$1,250 | Withheld from funding in this example. |
| Net deposits | $48,250 | $49,500 − $1,250; match to bank transfers. |
Real statements can include chargebacks, reserves, tips, taxes, prior-period adjustments or delayed deposits. Enter each on its own reconciliation line rather than forcing it into “processing fees.” If fees are collected by a separate end-of-month debit, deposits here would be $49,500 and a later $1,250 bank debit would complete the cash picture. The economic fee is the same; the funding method differs.
03 / Calculate the rate
Effective rate needs a matched numerator.
Effective rate is fees divided by relevant card sales. It summarizes an account's cost; it is neither a published interchange rate nor the processor's quoted markup.
All-card rate
The example's $1,250 fees cover all $50,000 of gross card sales, so $1,250 ÷ $50,000 = 2.50%. Using $49,500 net sales instead gives about 2.53%. Label and consistently use your chosen basis.
Same cards. Same period.
Include every fee you intend to measure and only the card volume those fees cover. Check for fee lag, another invoice and refund-heavy periods. One unusual month is informative but does not represent a year.
The all-in rate can change even when processor markup does not. A shift toward premium or online cards, different ticket sizes, minimum fees and one-time charges change the blend. Visa and Mastercard publish interchange programs with qualifying criteria, while the complete bill includes other costs. The fee comparison guide explains pricing models.
04 / Check the Amex boundary
Amex sales can dilute the apparent rate.
American Express says OptBlue merchants can receive one processor statement and combined payment. A direct Amex agreement may place charges on Amex's own records. Documents and fee bases decide the calculation; absence of an Amex fee line alone does not identify the program.
Swipe across to compare matched bases.
| Fictional situation | Calculation | Meaning |
|---|---|---|
| Processor fees only, but all card sales | $1,000 ÷ $50,000 = 2.00% | Misleading: $10,000 Amex sales present without its $300 separate bill. |
| Matched processor-only scope | $1,000 ÷ $40,000 = 2.50% | Visa / Mastercard / Discover only. |
| Matched Amex-only scope | $300 ÷ $10,000 = 3.00% | Amex only, if $300 is its complete July cost. |
| Matched all-card scope | ($1,000 + $300) ÷ $50,000 = 2.60% | Combined after both fee sources are included. |
Do not replace missing Amex charges with zero. Confirm that Amex sales occurred, whether they are inside processor sales, and whether costs were bundled in a tier, netted from deposits or billed elsewhere. A processor-billed tiered fee can be complete without an “Amex interchange” line. A direct agreement can include a discount and extra fees. Gather the matching record before claiming an all-card rate. See how Amex billing works.
05 / Name every charge
“Miscellaneous” is a starting point, not a verdict.
Read description, rate base and agreement before deciding a fee is unnecessary. Some categories are network costs; some are processor revenue; others pay for a chosen service or event.
Swipe across for questions to ask.
| Category | Examples | Ask |
|---|---|---|
| Card and network | Interchange, assessments, brand fees. | Which network or rule sets the charge, and what is its base? |
| Processor pricing | Markup, per-item, authorization, batch or account fees. | Where is it in the agreement, and is it negotiable? |
| Services | Gateway, software, reporting, equipment, paper statements. | Is it used or required? What are cancellation terms? |
| Events / compliance | Disputes, chargebacks, PCI-related charges. | What triggered it? Which remediation step ends an ongoing fee? |
| Periodic | Annual account, support or membership fee. | When does it recur, and is it in another quote line? |
A $99 annual fee appears as $99 of real cost in its billing month. In a full-year forecast it appears once, not every month. If ordinary monthly charges are $500, the year totals 12 × $500 + $99 = $6,099. An $8.25 monthly allocation helps planning; it does not change the actual bill.
Paying a PCI non-compliance fee does not prove compliance. Ask your acquirer what validation applies and which requirement remains open; the PCI Security Standards Council has merchant resources. Ask for a written explanation of unfamiliar lines instead of assuming every one is a “junk fee.”
06 / A repeatable review
Ten minutes monthly; deeper when something changes.
- Gather the full period. Save every statement page, relevant Amex or gateway invoices and bank transactions. Check dates.
- Reconcile activity. Add sales by network, subtract credits, identify chargebacks and tie funding to deposits with settlement lag.
- Total fees once. Use a summary total or itemized lines. Add separate bills, but do not double-count withheld fees.
- Calculate a labeled rate. Record fee and sales scope, date range and whether you used gross or net sales. Note unusual refunds or annual charges.
- Compare prior months. Investigate new fees, changed rates, unexpected tiers and fixed charges; request the agreement provision.
- Compare offers in dollars. Use the same card mix, count, channels and Amex assumptions. Include required software and annual charges once.
The free savings review starts with your actual statement. Payment USA's analyzer uses a 2.65% illustrative comparison benchmark; that figure is neither a card-network cost nor a personalized quote. A written proposal is needed to know what your business would pay.
