Time Tracking Software Resources

Want to start a discussion with G2 experts in the time tracking software community: what's the best time tracking software for billing multiple clients accurately without a mountain of manual invoice work? Most "best time tracker" lists only cover starting a timer, not turning hours into an invoice a client actually pays without back and forth.

Looking through Time Tracking Software on G2, here's what stood out:

• Toggl - reviewers doing consulting work say it's easy to track hours across a bunch of clients at once, though a few still lean on another tool for the invoice itself.
• BigTime - built for professional services billing. Reviewers call out billing down to individual tasks and controlling what staff can see financially.
• FreshBooks - turns time into an invoice fast, with Stripe and PayPal built in. One reviewer said comparing tracked hours to revenue showed their busiest service was actually their least profitable.
• Deltek Replicon Time - for firms with distributed teams and stricter compliance needs. Reviewers mention fewer billing errors, though pricing came up as a complaint.

For anyone tracking multiple clients, do you invoice inside the same tool or hand it off to separate accounting software?

Can employees swap shifts without manager involvement every time?
