Could you recommend software for solicitors bookkeeping?

I currently do the bookkeeping/reconciliations for my solicitor client on VT on a monthly basis. To record the Client account side of things I have set up a 'Client Ledger' and within that, the Analysis account for each client.

Each 'Client to Office account'  transfer necessitates two transactions to ensure that it is reflected correctly.

 What dedicated bookkeeping package is available to be used by accountants to maintain solicitor clients' accounting records? The main requirement being the ability to efficiently record the interactions between Office and Client accounts?

Thanks for advice
