Single touch have 3 products.
STP lite: $7.50 + GST per month, 30 employees included then 25c per employee, upload CSV (ie the above offer).
STP data: $5 + GST per month, 50 employees included then 10c per employee, upload data file (CSV or XML) via portal or API. Manager needs to have an ATO product id, which I think means it needs to be registered with with the ATO.
The later looks better to me and listing Manager on the ATO site is likely to be good marketing exposure for Manager.
