Avatax Calculations Are Slow (> 45 secs) in SuitePOS. Disable Avatax.
The Avatax Module ( because of Avatax) may experience degradation of performance during peak times. This has the effect of slowing sales down since SuitePOS relies on Avatax to calculate the tax. Severe delays are very rare and very temporary, however you may want to consider temporarily disabling Avatax so you can ring up sales quickly.
If the situation is dire, you will need to temporarily disable the Avatax Module and set the tax code to the backup tax code used for Avatax. This is done in the POS Settings record. When done, Avatax calculations are by-passed and the backup tax code on all transactions is used. In NetSuite, this also means that the tax documents will not be written to Avatax and will have to be manually adjusted in Avatax accordingly.
