CastorGrid mascot
Where construction, technology and people connect.

Run every project from one place

Everything your construction project needs in one place. Job logs, schedules, time clock, POs that sync to QuickBooks, and an AI agent that keeps clients updated — all from the field.

Everything a builder actually uses

Designed with field crews and PMs, not back-office software vendors.

Job logs

Daily field notes, photos, weather — captured from the jobsite in seconds.

Schedule

Tasks, dependencies, and a real calendar. No more spreadsheet gymnastics.

Time clock

Per-project clock in/out with GPS. Export hours straight to payroll.

Purchase orders

Issue POs, track delivery, sync to QuickBooks Online automatically.

CastorGrid Agent

An AI that drafts client updates and nudges the PM when something slips.

QuickBooks Online

Two-way sync for POs and bills. Finance stays in their tools, you stay in yours.

Simple pricing, by project

Per company, in USD. Guests are always free, on every plan.
