A wise man once sang that time keeps on slippin’ (slippin’, slippin’) into the future. But when you’re at work, it’s crucial to not let time, or expenses, slip through the cracks. OfficeTime is a robust time and expense tracker that scales from a single person to a small business. It’s great for tracking billable hours, creating invoices, and generating quick expense reports, and it syncs seamlessly between your Mac (or PC), iPhone, and iPad over the local network.
