Donovan Dressler has decided to try and cut his overhead by working from home. His mother is helping him with day-to-day office tasks until he can afford a new assistant. On Monday he returned from court and his mother advised him of the following items that came in the mail: A cheque from Client 4 in the amount of $1,000 for a retainer; an invoice from the LSO for outstanding fees of $1,500 including HST; and a cheque in the amount of $500 as partial payment on an invoice to client 3. Donovan also received an invoice from his former office for rent owed in the amount of $300.

 

Where should Dovovan deposit the partial payment from client 3? Explain.
