Hammr review

Field time and prevailing-wage payroll without replacing your ledger.

Verdict

Hammr is the wildcard because it attacks the part of construction accounting that goes wrong first, crew time and payroll rates, instead of trying to be another ledger.

What customers praise

The page describes managing multiple pay rates, prevailing wages and union rates, a mobile time-tracking app for field crews, crew scheduling, in-app messaging, and benefits and onboarding tools, with integrations to QuickBooks Desktop and Online, Sage, Xero and Acumatica.

What customers criticise

The page does not mention job costing, billing or retainage, and shows no prices; it sends visitors to a demo request. It does not replace a ledger or an AIA billing tool.

Best for

Contractors whose real accounting pain is field time and prevailing-wage or union payroll, and who already keep their ledger in QuickBooks, Sage or Xero.
