Hello, I hope you're okay. I need your advice, I just want your confirmation that Odoo community version 12 covers all my scenarios. da v12 community already has batch picking, zone picking, cluster picking and free module for barcode scanner.
there are a lot of dishonest people telling me we need to redevelop everything from the beginning. but i just need to configure Odoo to my scenario or not?
please help.
here is my scenario

We are a small start-up with limited resources and we want to sell on the internet. Our concept is very clear: everything has to run efficiently so that we save costs & everything runs smoothly. We will have a warehouse (about 100 square meters) and vehicles (with shelves) so that we can use the space in the vehicle well. The rule in the vehicle is exactly the same for all vehicles and has 36 compartments. The routes are first planned using open source route optimization software such as Vroom. There will be a shop in Magento.
I try to describe here again how exactly this should work:
1. the customers will order in shop
2. we plan the routes of customers. since we have a Capacitated Vehicle we can only transport certain amount (36 crates per vehicle).
3. on the basis of these routes picking lists are then created. The system must say how much boxes a customer needs. (Average volume and weight of the products and max weight and volume of the crates.)
4. using this information we can then create vehicle plan where the crates are placed in the vehicle plan, using this visual image.5.Picking: When the products are delivered, the employees store them on the shelves and mark them with a barcode. Then the picking begins. 
5.1 The employees pick up a trolley (marked with a barcode) and place 18 crates (marked with a barcode) on it. (Crates connected with shelves)
5.2 He runs to the starting point and scans the area (chilled or frozen, frozen is the last to be picked). 
5.3 On a device the picker is now shown where the first product is (shelf number), how many pieces he has to take and in which crate it comes.An algorithm (Multi or batch picking) arranges the orders and makes it possible that the pickers can collect several products for different customers at the same time and therefore only have to run through the shelves once (without running back). So all products are picked.
6. the runner will then drive the planned routes and should know exactly where the customer's crates are when he is at the customer's location based on the vehicle plan. 
That was now a rough explanation so you know how it all should works. I hope it was understandable. can we realize our concept with your solution? if not, please tell us what we can and can't do.
I'm waiting for your answer.
