Deterministic, rule-versioned rounding with an auditable record.
20 States. No Two Identical. No Federal Standard.
20 states have enacted a cash rounding law, 8 have legislation pending, and 5 have issued administrative guidance without a statute. Each figure is verified and dated in the tracker, not updated live.
The tracking is free. The compliance engine is the product.
Fragmented Across 20 States. Unregulated in the Rest.
Penny availability is declining. The 20 states with an enacted cash rounding law are moving at different speeds with different requirements, and 30 states have no enacted rule at all, which leaves the method to each operator. POS platforms, merchants, and financial institutions each face the same underlying problem: no standardized, jurisdiction-aware compliance layer exists. Centsless is that layer.

Legislative Observatory
The authoritative source for cash rounding legislation in the United States.
A state has a record if it has enacted a law, has legislation pending, has issued administrative guidance, or has had a bill fail. The four categories are counted separately above and together in the last figure.
