I noticed in your post that you are using Quickbooks to enter your disbursements and then reconciling to those entered in Time&Billing. I just wanted to let you know that Adagio Payables provides an automatic interface with Adagio Time&Billing. You can allocate an invoice directly to a file/docket in Time&Billing at the time it's entered into Payables (invoices can be allocated across multiple client/files) and the disbursement batch is automatically created for you in Time&Billing. You can control markups automatically.

Sorry to interject...
