CONCRETE CFO FIRMS, SCORED ON PUBLIC EVIDENCE.
How this was made: on October 31, 2026, Claude (Anthropic's AI model, Opus 5.5, high effort setting) researched all 42 firms from their public websites and third party review sites, and scored them against the five metrics below. The metrics and weights were fixed before the research started. Every firm's scores link to the pages they came from. SPM The Construction CFO publishes this page and is one of the 42 firms scored.
- C1 construction and segment fit, 20%
- C2 evidence of client results, 30%
- C3 third party trust, 20%
- C4 capability, 15%
- C5 transparency, 15%
Why this exists: subcontractors ask us who else they should talk to. This study answers that from evidence. Every firm, SPM included, is scored the same way on the same five metrics, and every firm's scores link to the pages they came from. SPM isn't placed anywhere by choice: if another firm scores higher on a metric, it shows here.
How often it's updated: every 2 months (next on December 28, 2026). Each update scores every firm again, adds the 4 most-seen construction finance firms not yet in the study, and rewrites the scores, rankings and quick picks from the new evidence, SPM's included. Corrections go in the log below.
SPM ranks first for concrete at 81.2 of 100 and is the only firm in the study with a concrete case study with numbers. Salisbury Bookkeeping is second at 60.8. SPM publishes this study and is one of the 42 firms scored.
SPM's concrete case study is anonymous, like every SPM case study; it is on SPM's client stories page.

WHO APPEARS FOR CONCRETE.
Three searches for concrete on one engine, standard mode, no location and no login, on October 31, 2026. The top 10 of each was recorded: 11 of the 30 results were firms that sell CFO, accounting or bookkeeping work.
- "CFO for concrete contractors"
- "accountant for concrete contractors"
- "bookkeeping for concrete contractors"
The research note for concrete, as recorded on October 31, 2026:
Mostly job boards and UK software blogs; only Fast Easy Accounting, Bench and Meru have concrete-specific pages; Contractor's Ledger concrete page is now just a redirect to a generalist CPA (Jahn CPA), not scored.
SPM's site was not in the top 10 of these searches.
