Need someone to setup on our Cpanel server a gateway that will have unlimited user accounts. This gateway will allow for a credit card terminal starting with the Verifone VX510 to log onto our server that will then log onto the merchants paypal account that has paypal and use paypal to process the transaction and then report the approval or denial of the credit card transaction to our portal/server and then to the machine. All of this should take place within 1 minute and require NO other interaction after the user has registered with our portal. Portal must have a PER transaction billing via paypal that can be set by the admin. Reciepts should print on the terminal for the credit card holder to sign and should disclose that the charge will appear as "Paypal-(merchant name)" cards will be either swiped or entered manually. Programmer MUST also be able to program this terminal to communicate with our server for this process to happen. This will be an ongoing process with terminals being added all the time. You must have the ability to once we start rolling this product out be able to re-program all types of terminals and be able to do so within 24 hours each time we contact you. Please when you apply explain exactly how you will make this happen so that we know you read this before applying. Thank you

Dear Developer. I am currently running a small shop that requires a POS that will be in synch with my website. The WooCommerse Point of Sale Plugin has accomplished this for me: https://codecanyon.net/item/woocommerce-point-of-sale-pos/7869665 However I am experiencing a few bugs, and would like to see them fixed along with a few custom updates. The support for this plugin has not been adequate for my needs. I would like to create a new plugin based on this one with these fixes and updates for my website. I would like to keep the existing plugin for backup. As we make sales in the shop, the plugin would need to work well, and we should perhaps test on a dev site before going live. • CHANGE: Move the Quantity field Between cost and Total. • UPDATE: Currently you can edit the cost of any item by entering a new dollar amount. I would like to have the option to be able to enter a dollar amount or enter a percentage. So if I am running a sale and it is 10% off just 1 item I can do that easily. Currently you can enter the discount on a % basis only on the order total which discounts each item. • FIX: Even when I set a register to Email, the email is still slid to "No" at the register. The register settings in the backend do not seem to change what happens on the front end of the POS. • FIX: The print option is not working at the register. It does set to print "Yes", or print "no", but it is then not printing. I certainly will need to print receipts for customers. However it does bounce me to a new page where I can print the receipt with a basic printer on an 8.5 X 11 paper. I would prefer to use our Star Receipt printer. • FIX: After the payment is processed, I get redirected. I would prefer instead to return automatically to the POS register. The problem with the redirect is that a lot of time when you go back to the POS and check the next person out you get a “Duplicate Invoice” error and need to then reenter the entire sale because the POS did not refresh between sale. • FIX: The bar-code printing option doesn't work. It will print everything else, but not the actual barcode. • UPDATE/FIX: The speed of the checkout is an issue. If there is a way to make it quicker, great. At a minimum it cannot get slower with these updates. Payment will be for completing all of these bugs fixes and updated features. Please let me know if you have any questions.
