The short answer
Read a Schedule A by identifying three things: the true cost basis for each line item, the padding added above actual cost, and the revenue lines excluded from your split entirely. Those three elements, not the advertised percentage, determine your effective split, which industry analyses often find 20 to 30 points below the headline number.
What a Schedule A Is
A Schedule A is the pricing exhibit attached to an agent or sub ISO agreement that lists the buy rates, per item fees, and cost allocations used to calculate residual splits. It typically covers interchange treatment, dues and assessments, authorization fees, statement fees, PCI fees, batch fees, and monthly account fees.
The agreement's split percentage applies to revenue above these listed costs. That makes the Schedule A, not the split, the document that determines income. Two agents with identical merchants and identical 80/20 splits can earn dramatically different residuals if their Schedule A cost bases differ.
Where the Padding Hides
Padding appears as costs listed above what the ISO actually pays. Common examples include authorization fees marked up two to four cents above cost, a BIN sponsorship or risk fee applied per transaction, dues and assessments quoted with a margin baked in, and flat monthly charges per merchant labeled as service or platform fees.
The second mechanism is exclusion. Many agreements keep 100 percent of PCI fees, statement fees, monthly minimums, and equipment revenue for the ISO. When padding and exclusions are combined, an advertised 80/20 split can produce the economics of a 50/50 split. Industry reviews of agent contracts find effective splits 20 to 30 points below the advertised figure with some regularity. Small basis point markups look harmless on paper until they are multiplied across millions in monthly volume.
How to Model Your Real Split
Take a live merchant statement, calculate total revenue above true interchange and network pass through costs, then run the same merchant through the Schedule A and compute your residual. Divide your residual by the total margin. That percentage is your effective split. Do this for a small retailer, a restaurant, and one larger account, because padding hits small tickets and small merchants hardest.
Run the same exercise on a residual report from a producing agent in the program if you can obtain one. A trustworthy Schedule A reconciles cleanly against a residual statement: every cost line traceable, every exclusion disclosed. Reports that lump costs into a single unexplained deduction are the operational version of padding, and they make auditing your own income impossible. The programs most confident in their pricing are consistently the ones that itemize.
Questions to Ask Before Signing
Ask which line items are at cost and which carry margin. Ask which revenue categories are excluded from the split. Ask whether the Schedule A can be amended unilaterally, because a document the ISO can change at will is not a pricing commitment. Also confirm how upfront bonuses interact with residuals, since some programs recover bonuses out of future residual payments. Get every answer in the exhibit itself, not in an email.
The Batch Group Sub ISO Program publishes its economics as aggressive buy rates with lifetime residuals vested from day one and no clawbacks, which is the level of clarity any Schedule A should meet.
Commonly Asked Questions
- What is a buy rate in a Schedule A?
- The buy rate is the cost basis the agent pays for processing services. Your residual is your split of the revenue collected above that rate, so a lower and truer buy rate means higher income.
- Can an ISO change the Schedule A after signing?
- Many agreements allow unilateral amendment with notice. Push for language requiring mutual consent for changes to buy rates and splits on existing merchants.
- Why does my 80/20 split feel like much less?
- Because the 80 percent applies only to revenue above listed costs, and those costs are often padded while several revenue lines are excluded. Model a real statement to find your effective split.
