Enhanced BillBack, and the bill that arrives a month late.
A low headline rate is charged at the time of sale, and the real interchange difference is recovered on a later statement. The two never appear together, which makes the pricing almost impossible to read and the true cost easy to miss for years.
What this page settles.
Three questions, in the order most people ask them.
How the model works
Enhanced BillBack, sometimes billed as ERR or Enhanced Recover Reduced, splits the cost of a transaction across two statements.
This month, you are charged a discount rate. It is low — frequently lower than any genuine interchange-plus quote you have seen, which is the first thing that should give you pause.
Next month, the processor recovers the difference between what they charged you and what the transaction actually cost at interchange, plus their margin. This appears as a separate line, often described as a recovery, a billback, or an enhanced adjustment, and it refers to the previous month’s transactions.
So the cost of October is spread across the October statement and the November one. Both are real; neither is complete.
Why it is so hard to read
Several things compound, and the combination is what makes this model distinctive.
The two halves never appear together. Looking at any single statement, you can see what you were charged for that month’s sales and a recovery for last month’s. You cannot see the full cost of any one month on any one statement.
The recovery line is rarely itemized. It is an amount. Tying it back to specific transactions, or to a published interchange category, usually is not possible from the statement.
The headline rate looks excellent. Because it is not the price. A merchant comparing their discount rate to a competitor’s interchange-plus quote concludes they are already well priced, when the comparison is not between two prices at all.
It shifts with your card mix exactly like tiered pricing does, with none of the visibility. A month with more rewards cards produces a larger recovery next month, and nothing explains why.
We have seen merchants on enhanced BillBack for several years who could quote their rate to two decimal places and had never once calculated what they actually paid. The model is not hiding anything illegally. It is simply built so that reading it takes deliberate effort nobody prompts you to make.
How to tell if you are on it
Four checks, and the first one usually settles it.
Look for a line referencing the previous month. Words like billback, recovery, enhanced recovery, interchange recovery or prior period adjustment, with a month name attached. If this month’s statement is charging you for last month’s transactions, you are on a billback model.
Check whether your discount rate looks implausibly low. A rate meaningfully below what interchange alone costs for your card mix is not a rate, it is the first half of one.
Check whether your monthly total swings without your volume swinging.
Ask directly. “Am I on enhanced BillBack or ERR pricing?” is a fair question with a one-word answer. If the reply is lengthy, that is informative.
What it actually costs
You cannot know from one statement, so do this instead.
Take three consecutive months. For each one, add every charge — the discount rate, the recovery lines, the fixed fees, everything. Add the three totals together and divide by the three months of card volume.
That is your real effective rate across the period, and it is the only number worth comparing with anybody.
Three months rather than one, because a billback has a one-month lag and a single month either includes a recovery for a month you are not counting or excludes one for a month you are. Over three the edges stop mattering much.
The result tends to surprise people. A merchant quoting a discount rate of around 1% is frequently somewhere near three when the recoveries are counted, which is not a scandal — it is roughly what their card mix costs — but it does mean the headline number was describing nothing.
What to do about it
Calculate the three-month figure first. Before any conversation, know your number. Everything else depends on it.
Then ask for a quote in a readable shape. Markup over interchange, a per-item fee, and a complete list of fixed charges. The worksheet for comparing is here. Price your real month through it.
Do not accept “we’ll lower your rate”. Lowering the first half of a two-part price changes nothing if the recovery absorbs it. The question is not the rate; it is the model.
Check the agreement for a rate review clause before you assume the current arrangement is stable, and check the notice period and any termination fee before you plan a move.
And a point worth being fair about: enhanced BillBack is not fraud, it is disclosed, and merchants do sign for it. But it is the model where the gap between what a merchant believes they pay and what they actually pay is widest, and that is reason enough to find out which side of it you are on.
What we charge
Interchange + 0.50% + 10¢ in person, interchange + 0.75% + 25¢ keyed. Everything for a month appears on that month’s statement, interchange itemized at cost, markup stated. There is no recovery line, because there is nothing to recover.
Send us three consecutive statements and we will tell you what you have actually been paying. If it turns out to be competitive, we will tell you that too.
While we are on the subject
Is enhanced BillBack the same as interchange-plus?
No, and the confusion is understandable because both reference actual interchange. Interchange-plus passes interchange through at cost with a stated markup, visible on the same statement. Enhanced BillBack charges a low rate up front and recovers an amount later that you cannot easily tie back to anything.
Is it legal?
Yes. It is a pricing model, disclosed in your merchant agreement. The objection is not that it is improper, it is that it is extremely difficult to evaluate, which tends to be the reason it is used.
How do I spot it on a statement?
Look for a line on the current statement referring to the previous month, often called a billback, recovery, or enhanced recovery adjustment. If this month’s statement is charging you for last month’s transactions, you are on it.
What should I switch to?
Any model where the full cost of a month appears on that month’s statement. Interchange-plus is the most auditable, but even a flat rate is easier to evaluate than a billback.
