For businesses that are not so large or complex or those that are very much cash-based, then we are big fans of Banklink.
Using the Banklink system, you record a code on cheques and deposit slips as you write them. This code is then picked up by the bank when they process your cheque/deposit.
At the end of each month we get a data file from Banklink which has all your data coded (well, most of it anyway). We then fill in the missing codes with your help. The Banklink software allows us to prepare your GST returns quickly and efficiently, and it also provides excellent cash based reporting.
