Bank deposits are simply entries made into the Check Register with a Type of D. They can be made either automatically or manually.
Automatic Entries include:
Deposits posted from the Customer Payments and Credits Browse.
Depositing an A/P Refund Check.
Manual entries are made directly into the Check Register.
YOU CANNOT COMBINE DEPOSITS!
Each Deposit made into Simple Accounting is a separate record in the Check Register. For example, if you enter ten Customer Payments and then Post them, this creates a Deposit in the Check Register. If you then enter another two Customer Payment and Post again, you will have created a second Deposit for the day. Likewise, if you post ten Customer Payments, and then enter a Manual Deposit directly into the Check Register, you will find two entries in the Check Register (and hence, two deposits.)
If you have different types of monies (several Customer Payments and one Vendor Refund) to deposit into the bank on a given day, you should divide these into two separate deposit slips. This will make reconciling your bank account easier since this is how Simple Accounting will record these as two entries in the Check Register.
