I prefer using mySQL as dB and PHP touch screen will be used with the program (no keyboard/mouse) so please keep that in mind for this project in regards to the interface development. (ie. large buttons for navigation and menu items, on screen keyboard/number pad) I would like a Point Of Sale system (source code delivered). The software is targetted to be sold with various businesses like local shops, pharmacies, clothing outlets etc. The system should be deveoped preferrably on ASP.Net / C# and SQl Server/Oracle . The software should manage in-store inventory, category wise and item wise. It should also help track sales through an item bar coding system. I will be installing a Bar code scanner and printer, so the software should work in such a way that code numbers and bar codes for new items can be generated in the software and be printed BILLING SOFTWARE Setup: Company Setup: User Setup: Rights: Receive SMS of Sales (End of The Day) Sales-Exp-C/c Receive SMS of PendingPaymentsReceivedOnlyWhenPayment isDone Receive SMS of Immediately for canceled bill Receive Email Of Sales Of The Day (End of The Day) Qty Price Total Receive Email Of Stock Report (End of The Day) OB | Pur|Sale|CB Receive Email Of Purchase (End of The Day) on that day if any Receive Stock Requirement Report (End of The Day)CurStock+order Receive Pending Bill Report (End of The Day)All Pending till not Paid SMS allocation to the company SMS through remote login Hidden inventory & Bill Tick Box For The Above Area Which ever is applicable to the User Category 3 >Printing Module Under Printing Module (Radio Button) O Pre-Printed Stationary O 40 Column Paper Print Msg 1 on Bill Print Msg 2 on Bill Category 4 : Ø Product Setup Under Product Setup Category Sub-Category Item Detailing of Each >Under Category SMS MSG Via Web / Modem SMS to Customer: BOX Festival Greetings BOX Send to all customers in data SMS for Sales of the day No Box Direct Text Format : PAS SALE Date:DD/MM/YY SMS for Pending Payment Received No Box Direct Text Format PAS Pend Rcv SMS for Bill Cancellation No Box Direct Text Format PAS Bill Can Category 1 Operations Generate a Bill Reprint Bill (Can Be looked up by Name/Ph no/ Bill No/Date/ Bill Payment EDIT (Only to Change it to pending / Credit Card/ Chq) Rest bill cant be edited Cancel Bill (Entire Bill has to be cancelled) by bill no Print Prev Bills Hot Key For Last Bill or Enter Bill Number Purchase(Option to purchase) Under Operations Category 2: Purchase(Option to purchase) Category 3: Issue Quotation: Reports Section All Reports for Current Day POS Restaurant - only one modification Purchase Kitchen items separately and costing of products.
