Two records, both confidence-marked cell by cell. The provider directory is wide: who supplies payroll data for which use case. The deduction record is deep: what a write at the deduction boundary actually expresses, system by system.
How every field is defined and scored: methodology.

Every entry carries the identical 10-field deduction record. Of 220 assessed cells, 100 are unverified — 45.5% — because no public source states the answer.

| Payroll systems by data capability What each payroll system will actually let you read and write at the deduction boundary. Products are listed separately, not companies — ADP Workforce Now, RUN, Vantage and Next Gen are four different contracts. | 18 | 180 | 84 (46.7%) |
| Unified APIs: the deduction record Employer-permissioned unified APIs scored on the same deduction record as the payroll systems they sit in front of. The question is not how many integrations they claim; it is what the deduction write actually expresses. Every other use case, and every other kind of provider, is in the provider directory. | 4 | 40 | 16 (40%) |
| 401(k) recordkeepers by payroll integration depth Which recordkeepers support 180-degree versus 360-degree integration, per payroll system. | 0 | 0 | — |
