I would have done this in Excel easily with some VBScript, but the solution has to be online and for mobile too.
Basically it is just an inventory of goods, with quantities, need to generate some reports, print them out and save few ascending serial numbers printed on the reports (invoices).
I immediately thought about Google Spreadsheets, but i don't think they can run scripts, and generate reports, or do they?
Any ideas on how to approach this?
Thanks in advance.
