Jurisdiction-Aware Cash Rounding Compliance for POS Platforms
20 states with an enacted cash rounding law, 8 states with cash rounding legislation introduced or advancing but not yet enacted, and 30 states with no enacted law. 19 of the 20 enacted states apply the symmetric five-cent table, and the enacted texts divide into 7 distinct mixed tender architectures. Centsless is the compliance infrastructure POS platforms integrate to deliver jurisdiction-aware cash rounding to their merchants without building or maintaining it internally.

The Compliance Complexity Your Merchants Are Navigating
20 Enacted Laws, No Uniformity
- 20 states with an enacted cash rounding law, 8 states with cash rounding legislation introduced or advancing but not yet enacted
- Arizona: Swedish rounding required when one-cent coins are unavailable, other methods prohibited (HB 2938)
- Connecticut: rounding permitted inside a prescribed total-price method, totals of four cents or less exempt (PA 26-128)
- Florida: permitted for sales tax dealers once the one-cent piece is no longer in production (SB 1074)
What Your Merchants Are Facing
- Exposure from rounding inconsistent with the applicable state rule
- State-level enforcement mechanisms that differ by jurisdiction
- Consumer protection questions where no statutory shield exists
The Build vs. Partner Decision
- Encoding and testing each state rule in-house
- Ongoing regulatory monitoring required
- Ongoing liability and maintenance remain with your team
Turn Compliance Risk Into Revenue
Rule Maintenance
We maintain the jurisdiction rules. Your team does not track legislative changes or re-encode state methods.
Revenue Share Model
A new revenue line from your existing merchant base. Commercial structure is set per partnership.
Available Now
An integration-ready rule set while others encode state methods internally.
Zero Maintenance
Rule updates are applied centrally as laws change. No engineering resources required on your side.
Append-Only Audit Log
Every rounding event is written to an append-only audit log whose records are chained and re-verified end to end.

Integration Built for POS Platforms
Illustrative only. The response shape is confirmed during integration scoping and is not a published API contract.

});
// Illustrative response:

Designed for platforms, processors, and enterprise partners. Commercial structures include:
API-based pricing (per transaction or location)
Revenue share arrangements
Volume-based licensing
Beyond the Penny
This transition may not stop at the penny. Our own research declines to forecast the nickel's elimination and notes that the dominant federal effort points toward preserving the coin. Centsless is designed so that if a denomination changes again, the same engine applies the new increment. That is a roadmap position, not a prediction.
