Know what your job sites are doing right now
Crews clock in on site, tasks update as the work gets done, and costs land against the job that caused them. You find out today, not when the paperwork catches up.

If you're good with a hammer but bad with the paperwork
ZenHammer is the office your crew carries. The people doing the work enter it once, in the field, and it turns into your hours, your costs and your invoices.

Know who is on site, without calling anyone
Draw a boundary around each job site. Time entries are tied to that area, so you can see who is inside it right now instead of phoning the foreman for a headcount.
Updates arrive as the work happens
Crews and subcontractors update their own tasks from the field, with photos and notes attached. It lands on your project feed the moment they save it.
Costs attach to the work that caused them
Materials and equipment are logged against the task that used them, so labour, materials and equipment add up per project while the job runs — not in a spreadsheet afterwards.
Everything the job needs, in one place
From the first budget request to the final invoice, without re-typing the same numbers into three different tools.
Time tracking tied to the site
Hours are recorded against the right job automatically, and can be corrected later when someone forgets to clock out.
Delays you can prove
Log weather, accidents and material problems with the delay each one cost, in hours, days or weeks — so when a date moves you can show exactly why.
Budgets out to subcontractors
Send line-item budget requests to several subs at once and keep the back-and-forth in one thread instead of a mailbox.
Invoice from work already recorded
Bill from the hours and materials the job already produced, and get paid straight to your bank account. Nothing gets typed twice.
Know what you already own
Track what is on hand, what is reserved and what it averaged out to cost across your warehouses, before you buy it again.
A schedule that argues back
Sequence the work and get warned when a task is scheduled before the task it depends on.
