How to create a service that allows customers to create their own invoices?

Question

1C-Enterprise

Good afternoon, dear connoisseurs.

The situation is as follows: we work with dealers, and most of the time it takes the formation of invoices for them. I think that this moment can be outsourced to the program.

As I see it: in 1C we have a database of dealers with their details. We also have a database with the current balance of the Goods. Each dealer has its own discount. The dealer enters the application, enters his TIN and drives in the necessary goods in the required quantity. The price for the goods is set automatically in accordance with the dealer's discount. If there is no product, the item is marked in red, he cannot order it and issue an invoice.

After the dealer clicks “Create an account”, the completed positions are frozen from the base with balances for a certain number of days (for example, for 3 days). At this time, no one else can order this Product. If after three days the Goods are not paid for, the position is unfrozen. If paid - this amount is deducted from the base.

We see in 1C that the dealer has paid for the goods and we begin to prepare the Goods for shipment.

I know that such services exist. You put the goods in the basket, then choose the payer (individual or legal entity), pay by bank transfer, fill in all the data and you will be billed.

But I can’t figure out how to correctly find these services, or those who provide and configure such functionality.

I would be grateful for any hints, tips, possible prices for writing such an application from scratch, suggestions.

Answer 1

According to the description, it is as similar as possible to an online store, just the details of the legal entity are also indicated.
So they offer to start the search with template online stores, how they can be expanded, and opportunities for integration with 1C (you may have to write a web component on the 1C side)
