Where to start? (or help?)

Hi, I don't know if I'm allowed to post this. I hope so. I'm a person who works a lot & has less time than I actually would like to have for programming/writing website code. I've tried to find a solution for what I actually want, but haven't found it yet. (Many projects I find give me just too much. Or maybe I'm looking up the wrong things. (I don't need any payment options.)) What I want is just to keep track what I have ordered with our suppliers, and when I receive some goods, that I can then link to my placed order. Status (ordered, partially received, completed, (+possibility to mark completed manually, for when the backorder is too small & they won't deliver the rest)). ( 0.0) customer) ( 0.1) products (customer, title, type [box/roll], measurement type [pieces/meter], [sortId (= a custom field where I put my own code for sorting ordening purposes)])) ( 0.2) suppliers (for those products, products can have multiple suppliers))

1. orders (create date, product, amount ordered, supplier, confirmation date of the supplier, order number given by the supplier) (part of the order can only be filled in (/added) later) (maybe even a possibility for a suggested delivery date)
2. receiving (receive date, amount received, delivery number, (linked order number), [add (pdf) file attachment]) ( 3) invoices of the received goods)

a) I have already a website (not Laravel, made by someone else, but that I have already customized a little bit more) to keep track of the current stock of our materials. (So I already have a database that has many things that I would need for this one too, just need some additional tables.) b) I now want to have a way to keep track of what has been ordered, and when delivered, that I can link the delivery with the order. When order complete, it may go off the overview list (or after a button is pressed by someone who checks the invoices against the delivery documents). (But maybe still searchable for in the future, maybe in a kind of archive page). c) Maybe also a page to add/edit "products", "suppliers". (adding new products is currently done with the (android) app that has been created to make it possible to move a pallet to another place, to remove them out of stock, etc.)

Friendly greetings, Valcav
