Online store for wholesale and dropshipping sales from its private cabinet

A need for an online store with specific features. For wholesale and drop sales. I already know of a similar ready and working version, if someone is interested to see how it works in reality, and what I specifically need (essentially almost everything that is there) the site is here account . opt-drop . com (remove extra spaces).

1. Sales are available after full registration, in the closed admin part of the client, and possibly client activation even by the admin. Without registration, only the front-end side is visible, a product catalog with prices, but without the ability to place an order.

2. Two prices. Wholesale + Drop price.

3. Own balance/account of the client, from which these funds are deducted when placing orders. The ability to top up this balance both by the system admin and by the client themselves, through payment systems. Display of deductions.

4. The ability for a partner to place an order for themselves or for a client with the attachment of a file of their own labeling (PDF) of the new mail. (I showed in the screenshot how this is implemented in the same example).

5. Management of product stocks is possible directly in the system, or for example through integration with the SalesDrive crm warehouse via API.

6. The ability for clients to connect to the site via API.

7. The ability for XML/Csv export (products, characteristics, photos, availability) for adding products to websites or to marketplaces PROM/Rozetka.

8. The possibility of integration with SalesDrive for clients.

9. Adaptability for mobile devices.

It is preferable that everything is developed by one group of people, rather than searching separately for designers, etc.

Development is desired to be not long. Around 1 month.

It is preferable to orient on price, as the budget is also not flexible here unfortunately. The budget here is of course indicated from the ceiling. It will be by agreement.
