How can I use the form to enter informtion into a spreadsheet to submit later?

Is there a way to have a form set up where information is entered into the form and then its places into the proper cells in a spreadsheet within the form, where multiple entries are made and then it is sent to the spreadsheet. After the Spreadsheet is full then it will be able to be submitted. 

I am needing to track the customers I have, However submitting one form for each person is going to be overwhelming not only for my employee, but for my self when I go to look at the submissions

I am not sure if I understand your query correctly. Do you mean to have the spreadsheet on the form to be saved each time the form is entered without submitting it? Unfortunately, it is not possible to save the data to spreadsheet without submitting the form. If you need to save the information to a spreadsheet, you may consider generating an Excel report for the submissions received or integrate Google Spreadsheet to the form so that the each submission will be updated automatically.

We do have a Save and Continue feature to submit the form later. But I don't think it works for your requirement. Please go through the guide below and see if that helps in any way.
