Hi Kylie,
Apologies for the late reply.
Numbering isn't an issue for us.
The default is that quote get a Q prefix, sales orders an S, invoices an I etc. That is the default setting and can be changed. The numbers after the prefix aren't synced either.
The improvement in efficiency is that once a part has been quoted successfully and a customer PO is received it can be instantly turned into a sales order confirmation. From the sales order a supplier purchase order can be generated (or added to an existing supplier PO) if the part isn't in stock. When the part is in stock we can mark it as "shipped" and the invoice is generated automatically. To do all that in MYOB alone requires a lot more work.
This is only a small part of what TE is capable of but we find it extremely useful.
Most of our supplier purchases are imports with long lead times. I've also found TE useful for filtering supplier purchase orders to see what we have on back order.
