Management Spreadsheet for confectioners

I already use a management spreadsheet for confectioners, but I would like to add other items to this spreadsheet and use the colors of my bakery.

The spreadsheet will contain:

customer management

order management

technical sheets

pricing

cash flow

The spreadsheet will have a menu with buttons that will direct the person to each tab. I already have these spreadsheets, but I would like to centralize everything in one and have my profile.

I have included it in the attachment, but as I said, I would have to add other buttons.
