I am trying to add shareholder contribution that was paid from a private account and sell my tools and product to the company. How do i properly log it in to the journal.

1. It seems that you have made an investment to another company and paid the shareholder contribution from your personal account. If that so, then you need to pass the following Journal in your Quickbooks.

Investment in _____ Company A/c (classified as Assets) Debit

Owners Contribution (Equity) a/c            Credit

2. For entering the sales transaction, you should use either invoice or sales receipt.
