i want to develop Point of S A L E system. can anyone help me can anyone tell me what type of module i need to add. or any other information.
Well you would need to do some research before you started. Is barcode required? Keyboard Input? How many products are you wanting to cater for? What Data you want to be able to store? What reports and information you want as outputs? The principle of a POS system is simple, you enter a product and quantity, then it is removed from the available stock. You need to be able to add new stock as it arrives to the system, which will need to be quick and efficient to do. You would want to get statistics on a daily, weekly, monthly basis. If you decide you need barcoding, you need to find a hardware supplier, possibly looking for some kind of API to use it.
yes agree with lukefowell89. You need research before you establish your point of sale. Point of sale depends on nature of your products. Are they general store products? Are they software products? visit some online stores related to your idea register there and observe which services they provide with which type of features.
