To make sure the e-commerce extension or plug-in is compatible with your ERP, testing is required. Depending on whether a plug-in for your system is available, this process normally takes 1-6 weeks. If there isn’t already an appropriate plug-in, we’ll work with a developer to make one.

No, but if used our system will try to correct it

1 space, usually state and zip code can be set in two different places in seller system. 

Q: What rate does SutTax use if it doesn’t recognize the address or if the address is in the wrong format?

Depends on the state, system will try to match street, zip+4, then zip, or error. 

Q: Address verification link?

Zip code lookup 

Q: Is it possible to expand the sales tax rate that the Avior solution uses to three decimal places?

The system does use tax rate with 4 decimal digits, your extension is doing the rounding and we are fixing that in next extension release.
Q: How does the system handle words that are spelled wrong…like the name of a street or the name of city?

The system will try to standardize the street or city names based on USPS database. In the case of spelled wrong words, the system tries to match street, zip+4, then zip, or the extension gives error if it can't match in database.
Q: This works for us at the transaction level, now how to make it work at the reporting level. Is there a way to get reports out of the Avior system that will break down the sales tax by city, county, and state?

2 options to get your transaction details:
1. You can use the extension to get the data, the break down is in the current extension debug trace. Future extension release will dump data to separate CSV file.
2. You can get the transactions history in CSV file from the tax engine.

3 options for filing and payment:
1. File it with state yourself and remit payment.
2. Upload the transactions csv file to Avior SutTax-C and the system files it with the state, and can include payment.
3. SutTax automated filing, the system can file sales tax return automatically at month end from history transactions, and can include payment.
Note, options 2 & 3, this limited to states accepting automated filing.



Q: How will I be charged and billed for my use of SutTax Determination?

How many transactions you complete per month will determine SutTax Determination’s subscription fee. An invoice line item is regarded as a transaction.
