Jon -

My suggestion is to do your weekly payroll in the payroll module, just as you would if you were doing it in-house.  Then find a provider that will accept an export file based on your pays, deductions and taxes as you calculated them.  Then when you receive the paper copies of the payroll reports back, it should just be a matter of Generating Direct Deposits, Print Checks (assuming you use the same employee sort in Timberline as the provider) to the same check numbers, and post the payroll.  I have switched a few clients from the providers that don't allow you to control what is paid in taxes to CheckWriters.  They accept a Timberline Report generated to a txt file as their import.

When I last checked, both of the major providers (ADP & Paychex), both require you to use their tax calculations, which is always a few cents off and makes balancing the payroll between the 2 systems tedious.

You could extend the automation and have a report written to export the IRS, State Withholding, Garnishments, providers fee, etc. from payroll into AP Invoices for those deductions coming out of the checking account.

Just my experience,

Why not process the payroll fully in-house?  Sounds like you are doing the bulk of the work in-house already.

We prefer not to process the direct deposits--along with the handling of 941s and multiple state tax withholdings and SUIs.

Those steps are pretty straight forward in Sage and Aatrix for tax filings.  You may want look into it as an option.
