Roundhouse also have a Sage 200 pro add-on (which records changes to the customer account, e.g. change of credit limit). The "new" version of sage 200 does record changes to PL bank detauls (and purchase reqs) - which is very handy (and you can exclude access to the supplier bank tab on the amend account form)

Agreed get asked for these all the time who has added this stock item, who has amended this etc. definitely need more auditable of record creation / amendment.

There's functionality there for PL bank accounts and Purchase Reqs in winter 18, so hopefully they will increase this to save people getting a sicon addon
