Architecture — Product & Monetization

More programs fail on economics than on compliance or technology.

The margin isn't there. Interchange is lower than projected. The BaaS take rate is higher than expected. These are not market problems. They are program design problems.

Where Programs Break Economically

The four economic failure modes

01
Interchange lower than projected
Card type, BIN structure, and Level 2/3 data transmission were determined by vendor defaults rather than program design. The economics were modeled against the wrong interchange assumption.
02
BaaS take rate higher than expected at scale
BaaS pricing that works at low volume becomes untenable at $50M+ in processing volume. The model wasn't stress-tested against the growth trajectory before the program was built.
03
Float revenue captured by the bank
Customer balance float retained by the sponsor bank because the commercial relationship wasn't structured to share it. Revenue that could belong to the program sponsor is going to the bank by default.
04
Fee structure that doesn't reflect value
Transaction fees, subscription fees, and FX margins inherited from vendor default schedules rather than designed against program value. Programs consistently undercharge when fees aren't designed explicitly.
05
Last-mile revenue gap — the monetization layer was never connected
The program is live. Payments are processing. But the monetization infrastructure — interchange routing, float mechanics, fee execution logic — was never wired into the program. Most programs that fail to capture payments revenue didn't make a wrong decision. They made no decision. The fee structure, interchange routing, and float mechanics defaulted to vendor configuration because they were never explicitly defined. This is an architecture gap, not an operational one. It's fixed at the design stage.
What Fee Design Actually Requires

Designing a fee structure is not benchmarking competitors. Competitor pricing reflects their cost structure, their volume economics, and their willingness to compete on price — none of which are necessarily relevant to your program. Benchmarking anchors the conversation at the market floor rather than the value ceiling.

Fee design starts by quantifying what the program eliminates or enables for the customer. An ACH transaction replacing a check — where the all-in check cost is $8–15 per payment — justifies a very different fee than one priced against the ACH rail cost. A same-day payment premium priced against the receiver's working capital benefit captures a different fraction of value than one priced against the rail cost differential.

Three fee elements missing from most programs: speed tier pricing (same-day and instant delivery priced against receiver value, not rail cost); data and reporting fees (remittance products, ERP integration feeds, and exception management charged separately from transaction execution); and exception pricing (returns, reversals, and manual exception handling priced to recover cost and incentivize cleaner payment behavior).

Revenue Architecture

Ten levers that determine payments revenue

These are the specific program design decisions that determine whether your payment flow generates revenue — and how much. Each is designed as part of the architecture, not discovered after launch.

LEVER 01
Interchange Architecture
BIN structure, card type, network selection, sharing agreement terms.
LEVER 02
Float and Balance Revenue
Account structure and bank relationship terms determine who captures float.
LEVER 03
Fee Design
Fee structure designed against program value, not inherited from vendor defaults.
LEVER 04
Program Model Selection
BaaS vs. direct vs. hybrid sets the ceiling on every other lever.
LEVER 05
Sponsor Bank Relationship Terms
Float economics, revenue sharing, compliance cost allocation — negotiated before the conversation.
LEVER 06
Payment Speed Control
Rail cost vs. delivery price spread. Three pricing models: transactional, subscription, tier-embedded.
LEVER 07
Custom Integration and Aggregation
ERP connectors as billable products. Implementation pricing + platform tier pricing.
LEVER 08
Custom Remittance
Five remittance products. Two-sided monetization. Remittance data is worth more than the payment.
LEVER 09
Payments Sold as Efficiency to Adverse Payers
Receiver-side monetization when payers won't pay. Speed fees, dynamic discounting, AR financing.
LEVER 10
Flexibility in Delivery and Cascading
Programmatic delivery waterfalls. Premium delivery tiers. Revenue on re-delivery.

The full detail on each lever — including specific design approaches, benchmarks, and implementation guidance — is in the Payments Monetization framework.

What the monetization design work looks like

The revenue architecture is designed before the build — or it isn't designed.

Interchange capture, float economics, and fee structure get locked in at the program design stage. The programs that capture them are the ones that design for them explicitly.
