Our client requires the following:
1. An invoicing application to run on a MS Windows OS PDA which will contain their:
i) Customer Details
ii) Product Information (all details) and selling price
2. A deskptop application running under Windows XP / Vista which will synchronise with the PDA (when the unit returns to base).
In the field, the PDA would be used to generate an invoice at the time of delivery, obtain the signature of the receipent of the goods (buyer) and when the unit is returned to base, the PDA would update (upload) the invoices generated on it to a desktop computer which would store a database of all the invoices generated (and delivery signatures) thus then allowing the user on the desktop machine to either: a) print the invoices; b) send the invoice via an e-mail; or c) export the invoice to any popular accounting software (point "c" is optional).
Please provide me with your best quote for this application with the option to export the invoice to any accounting package, and without this functionality. Also, obtaining a signature at the time to delivery on the invoice is optional - so, please quote a price with and without this facility.
If you need any more clarification or explanation, please ask me on here before you quote.
Kindly indicate the lead time required to create the application as well.
