This may work for some time but this approach may generate high fees for the short term and also be in the best interest of the client(all needed requirements completed) but the first low ball estimate from the competition and revenue is lost forever.
To protect your client from this the best approach is to make sure your client understands the difference between quality service and something inadequate yet inexpensive.Many accountants avoid this conversation with clients wary of getting negative feedback from the client but it's a conversation that must be undertaken and will save the accountant revenue and provide the client with the best value. Inadequate service at low ball prices is quite simply a rip off .
