   1.                                                   We note that the
calculation of annualized recurring subscriptions and usage revenue
                                                        (ARR) includes platform
usage charges for all CPaaS customers (subject to minimum
                                                        billings threshold for
a period of at least six consecutive months). Please tell us what
                                                        usage charges you are
referring to here and revise to clarify whether certain usage fees are
                                                        excluded from this
measure. In this regard, your revenue recognition policy refers to
                                                        bundled and non-bundled
usage fees. Also, Fuze's policy referenced variable usage fees
                                                        for blocks of
additional minutes and other items systematically purchased in excess of
                                                        plan limits. Refer to
SEC Release No. 33-10751.

2.       You state that service revenue increased during fiscal 2023, primarily
due to your installed
         base of mid-market and enterprise customers, expanded deployments by
existing
         customers, and growth in related telecom usage by your customers. You
also refer to a
         partial offset due to a decrease in usage revenue in the Asia-Pacific
region. Please revise
         to disclose the dollar or percentage change in revenue due to new
versus existing
         customers. Also, tell us your consideration to disclose the number of
customers in your
         installed base as you do in your Form 8-K earnings releases for your
enterprise customers.
         In addition, where two or more factors contributed to a material
change from period-to-
         period, including any offsetting factors, revise to include a
quantitative discussion of such
         factors and avoid using vague terms such as "primarily" in favor of
specific quantification.
         Similar revisions should be made in your Form 10-Q filings. In this
regard, you refer to
         various factors such as increased churn, down-sell in your inorganic
customer base and
         lower revenue in Southeast Asia region, partially offset by new
subscription revenue and
         new organic bookings as contributing to the decrease in revenue during
the three and six
         months ended September 30, 2022. Lastly, explain your reference to
"inorganic" customer
         base and consider quantifying churn in future filings. Refer to Item
303(b) of Regulation
         S-K.

3.       We note that international revenues comprised 27% of total revenue in
fiscal 2023. Please
         tell us whether revenue from any individual country is material, and
if so, how you
         considered the guidance in ASC 280-10-50-41(a).

4.       We note you refer to adjusted EBITDA as a percentage of revenue in the
financial results
         bullet points without also presenting the comparable GAAP measure of
net loss as a
         percentage of revenue. In addition, you disclose various non-GAAP
operating expenses as
         a percentage of revenue without disclosing the comparable GAAP
operating expense as a
         percentage of revenue. Where you present non-GAAP measure, please
revise to ensure
         that you present the comparable non-GAAP measure with equal or greater
prominence.
         Refer to Question 102.10(a) of the non-GAAP C&DIs.

5.       We note your measure of non-GAAP net income does not appear to include
the income
         tax impact of your non-GAAP adjustments. Please revise to include a
separate income tax
         adjustment commensurate with your non-GAAP measure of profit. In this
regard, while
 Kevin Kraus
8X8 Inc.

      we note that you have a recognized GAAP pre-tax net loss and a valuation
allowance
      against your deferred tax assets in recent years, you have also reported
non-GAAP net
      income in the same periods such that a valuation allowance may not apply
on a non-
      GAAP basis. Revise or explain further why you do not believe an income
tax expense
      adjustment is necessary. Refer to non-GAAP C&DI Question 102.11.
       In closing, we remind you that the company and its management are
responsible for the
accuracy and adequacy of their disclosures, notwithstanding any review,
comments, action or
absence of action by the staff.
