What it is
Costlocker is a business tool for tracking agency time and costs and examining profitability by project, client, and employee. It records billable and non-billable hours and connects tracked time to salaries, roles, and billable rates. Teams can set project budgets, compare estimates with actual costs, and monitor budget use as work progresses. Reports cover profitability, while revenue forecasts can use budget expectations and planned workloads. Costlocker is available on the web, iOS, macOS, and Windows, with REST and GraphQL APIs. A Make integration is available by invitation through support. The All-Inclusive Plan is listed at $12 a month, billed monthly, with unlimited projects and clients, desktop apps, API integration, and chat and email support; only active users are charged. A 30-day trial requires no credit card or payment details. The company lists a Help Center, Quick Start Guide, system status page, and developer API documentation. Its terms state that the service is for business use and not intended for consumers.
