Start-up capital and contribution of equipment and PPE for a sole proprietor as a secondary occupation

I started as a self-employed sole proprietor in secondary occupation on 02/05/2024. I have just started using Dexter.

I incurred a number of costs before my company number was activated. To pay those costs (and have enough capital to pay the bills before I receive income), I deposited some ‘start-up capital’ into my business account in advance. How do I record that start-up capital?In addition, I have a number of devices and PPE that I already had and that I need to perform my services. How can I enter these as business assets? For some items, I have an invoice in my own name (without a vAT number), for others I no longer have an invoice (or receipt).
