ContractLog is the easiest way for subcontractors and field crews to track hours, mileage, per diem — and generate professional invoices in seconds.
Designed specifically for field crews — not adapted from generic software that never quite fits.

Generate PDF and Excel invoices with one click. Contract limits, line items, totals — everything formatted and ready to send.
See a full breakdown of hours, mileage, and spend by project, person, and month. Know exactly where every dollar went.
