Our Mistakes

- not preparing the psudo code of the system. - not recording the shop item master & item master file item data with a batch number(we used a grnnumber instead for stock). - allowing the user to backup & restore the database with same difficulty withing the main system. - formatting error in entering item prices (ex: we used 55.5 instead of/which must be 55.50). - not recording the supplier invoice with a ref number to that invoice. - not having a relationship with the two txn_master & txn_details tables. - in the invoice summary report giving the whole invoice grand totals without summarizing them by day. - errors in naming the master & details tables(ex : txn_master & txn_details). -in system documentation just saying "documentation" without saying --> "system documentation". - allowing an order id to be present in more than one grn. - naming the menu that opens the item billing form as "billing section" without saying "billing screen". - in the billed items grid having an unnessary field called "purchase status". - when billing the same item twice not having them as two seperate rows without checking and appending the item qty to the previously billed item qty of the same item.
