Good packagist for Laravel Inventory system

I have a project and need this thing, but I can't find a word to search for it.

to reduce development time, so I think it's better to have a packagist install.

I have Inventory which stock goods.

Each unit has a different volume and weight, or even have smaller units inside it. (Can you readers get it to this point? There were boxes inside a box. Like you guys buying a whole big M&M box)

Right now I stock everything in the smallest unit for example:

• a sack of flour is 25Kg, and I stock it like 25.000 grams (if there is 20 sack of flour it's always stock like 20*25000= 500.000grams)
• a big box of choco powder with 20 small boxes in it. and each small box has 5 small plastic packs in it. (if there is 10 box of choco powder it's always stock like 10*20*5= 1.000 packs)

and what I requesting is a packagist that can write down every product details and convert it in view like:

• flour stock left = 5 sacks - 2.5kg
• choco powder stock left = 2 big box - 17 small boxes - 2 packs
