One case per client, per year, per work type — corporate income tax from the ECI through the Form C-S / C, personal income tax, ACRA annual returns, IRAS queries and ad-hoc engagements — with every deadline generated from that client's financial year end. Your team shares one case list and every update is logged against the person who made it, while client names and UENs are encrypted in your browser before they are stored. Access is by request.
