You can create a vendor account on fintechee.io
After you finish developing the EA for this client, you can upload a zip to fintechee.io and make a product item projected to the zip.
You can set a price for the product and inform the client to pay for the bill.
Once you receive the payment, you can remove the product item.
Removing items is not necessary for other products.
Because you are providing an exclusive freelancer service, so you need to remove the item.
Please refer to this article to know how to sell your service(product). How to Sell – Fintechee EA Marketplace
Please note, currently fintechee.io is under the sandbox mode.
So the payments are not real. We will open a live payment gateway next year.
