We do thousands of time entries a month in QB online across 30+ employees. We got so tired of the constant issues that we built time entry (weekly view, single entry view, and timeline view) into our employee portal product and it syncs directly with QB online. You can even save presets for time entries you put in regularly, which is awesome. It's been a huge time saver for our team.
