Hello Suphasuda,
Thank you for getting in touch.
The invoice USD1100.00 was for CC SPPS membership 2015-2016 ( this includes the software access + the proficiency flavor capsules packs for the panelists at 4 times per year ).
In addition to this, you may also want to budget for the on-going panel's maintenance training using the off-note training kit ( CSD kit @ usd1000 per kit and water kit @ usd1000 per kit ).
Does your plant produce both CSD and Water? If so, you may need to budget for 1 kit each, total USD2000 per year.
Hope this explains.
