Timesheeting tie ins for Advanced?

Hi all,

I've had a prospect ask me the question, is there a good Timesheeting tie in for Advanced.

They're a contractor, who is looking for ideally:

Integration from Advanced

• Pull employee settings
• Pull Job settings
• Be able to define what Time types and allowances are available, and billable, as part of this pull.

Employee Portal

• Note down what hours they worked, allowances accrued, leave applied for.  Job/TimeCode enforcement from Advanced Integration

Customer Portal

• Approve Hours worked by workers as having happened/being good to bill/good to pay.

Supervisor Portal

• Approve Hours worked by workers as having happened/good to pay.

Integration to Payroll

• Give approved time details to Payroll for Payroll to pay people
• Possibly give Costing information for Jobs/Projects (if Payroll is going to generate the costing journals.)

Integration to Advanced

• Give approved time details to Advanced for Billing via Jobs/Projects
• Give approved time details to Advanced for Costing via Jobs/Projects (Possibly via Payroll)

I know there are a huge range of timesheeting applications out there for contracting companies/service companies, so I imagine there's probably an exact right fit for my prospect out there somewhere.  Hoping to hear about good/bad experiences from the rest of the community before I steer the client down a particular path.
