Here is the problem: company brings in a whole bunch of sales reps. The sales reps want to be able to provide their clients the ability for them to check their own stuff. But the sales rep can’t give them their access into the website area because then the other companies will be able to see what he gave them for a price vs the other company and just would be a bloody mess if they found out. The sales reps create their own company in this case. They then go out and get all of their clients and then take a markup on the gas, etc. Solution: I have already started the front end of the website, but need help with the database end of it because the people will have to input the changed numbers for that specific company in the access project that you would build. Each company would have their own login and their own data that they can view so no 2 companies could see each other’s information. Goal: To have logins for each company and then to have the ability to easily add Company ABC if he finds and sells another station. Would have to be able to add that company easily on the backend and to emulate all of the reports that need to be seen. The main reports that you need to look at in the following login that I give you to the are as follows: My Account In this area – they would need the ability to be able to update the following if it changes 1) Email, address, cell telephone, telephone number, fax number. My Documents Needs the ability to input the following data into the credit cards, draft notices, and invoices. My Pricing Needs the ability to input the following data for each stores pricing. We will need to make sure each company has a login and a login area specific to their page - and we need the ability to add a company on the fly automatically and then disable them, if for some reason they are no longer a customer. We can and will provide you logins to the appropriate accounts to see the reports and what is pulling. Need the ability to upload excel / csv docs. Please contact me if interested.
