Draft Registration Statement on Form S-1

Prospectus Summary
Overview, page 1

1.     You refer to your annual revenue run-rate ("ARR") for the periods
presented here and
       throughout the prospectus. Please define the ARR metric here or provide
a cross-
       reference to such disclosure.
Market Size and Opportunity, page 4

2.     You state that you believe your total addressable market is materially
larger than
       ecommerce platform spend due to the additional revenue share that you
earn from your

         technology partner ecosystem. As the estimate of market opportunity
for ecommerce
         platforms appears to include spend on both software-as-a-service
("SaaS") and legacy
         software, please also discuss the effect that the continued strength
of legacy software may
         have on such estimate. In this regard, we note your disclosure that
legacy software is still
         prevalent for the largest retail businesses and that only within the
last five years have
         multiple SaaS options begun to challenge legacy software leaders in
the small, mid-
         market, and large enterprise segments. Also, while we note your
discussion of the
         disadvantages of legacy software throughout the prospectus, please
address whether there
         are any material risks and challenges that legacy software has posed,
or is expected
         to continue to pose, to your business. In this regard, the first risk
factor on page 35
         suggests that the challenge of converting businesses from legacy
software to SaaS is
         magnified in the case of highly regulated industries.

SaaS platform for
         cross-channel commerce.
Risk Factors
Our success depends in part on our partner-centric . . ., page 21

4.       You disclose that certain of your strategic technology partners,
including PayPal, Google,
         and Stripe, generate significant revenue for you. In this regard, we
also note your
         disclosure in Note 2 to the financial statements on page F-11 that one
partner represented
         12% of your revenue for the fiscal year ended December 31, 2018. To
the extent that any
         particular partner has continued to represent a significant portion of
your total revenue and
         the loss of such partner would have a material adverse effect on your
business, please
         enhance this risk factor by highlighting that fact and specifying the
partner from which
         you derive that revenue, and describe the material terms of the
contract governing such
         relationship. Also, please clarify whether your contracts with
strategic technology
         partners are cancelable.
Risks related to owning our Series 1 common stock and this offering, page 41

5.       Please address in a risk factor the extent to which your directors,
executive officers, and
         persons holding more than five percent of the outstanding shares of
Series 1 common
         stock will be able to exercise significant influence over any vote of
the Series 1
         stockholders after the offering, as well as the anti-takeover
implications of such
         concentration. Also, disclose the percentage of the Series 1 common
stock that they will
         together beneficially own following the offering in the prospectus
summary.

The provision of our amended and restated certificate of incorporation
requiring . . ., page 47

6.       You state that the exclusive forum provision will not apply to suits
brought to enforce a
         duty or liability created by the Securities Act of 1933 or the
Securities Exchange Act of
         1934. The corresponding disclosure on page 125, however, indicates
that the provision
         will require that claims arising under the federal securities laws
must be brought in a state
         or federal court located within the State of Delaware. Please revise
to reconcile these
         disclosures and clarify whether the exclusive forum provision will
apply to claims arising
         under the federal securities laws in any manner. If the provision will
apply to claims
         arising under the federal securities laws, state that there is
uncertainty as to whether a
         court would enforce such provision and that investors cannot waive
compliance with the
         federal securities laws and the rules and regulations thereunder. If
the provision will not
         apply to claims arising under the federal securities laws, please also
ensure that the
         provision states this clearly, or tell us how you will inform
investors in future filings that
         the provision does not apply to any claims arising under the federal
securities laws.
Market, Industry, and Other Data, page 49

7.       We note that you cite estimates and statistics from a number of
third-party publications
         and reports throughout the prospectus. In addition to identifying the
third parties, please
         provide the name and date of each publication or report that you
reference.
Use of Proceeds, page 50

8.       Please identify any executive officer, director or any of their
affiliates who will be
         receiving offering proceeds pursuant to the Series F Dividend, and
quantify the amount
         each will receive. Provide this disclosure in the aggregate under the
summary of the
         offering on page 12.

Operations
Overview, page 60

9.       You disclose here and throughout the prospectus that the 60,000 online
stores that you
         serve represents your customer base. As your customers may have
multiple stores
         running on your platform and your growth strategy is dependent in part
on selling
         additional stores to existing customers, please contextualize this
disclosure by providing
         the number of businesses and stores on your platform for each period
presented. Also,
         given your particular focus on acquiring, retaining, and growing your
mid-market and
         large enterprise customer base and the fact that the increase in the
number of mid-market
         and large enterprise customers has been one of the primary
contributors to your revenue
         growth, please break out such information by type of business. In this
regard, we note the
         growth in your mid-market and large enterprise customer base is not
clear because your
         accounts with annual contract value ("ACV") greater than $2,000 metric
includes not only
         customers on Enterprise plans but also customers on Pro plans and
customers with
         multiple plans that together exceed such threshold. Finally, in light
of the strategic

         importance of large enterprises to your business and your statement
that the power of your
         platform to support their growth better than legacy software is
"evidenced by the large and
         growing number of category leaders and Global 2000 businesses that
select you as their
         ecommerce platform of choice," please also specify the number of large
enterprise
         businesses and stores on your platform for each period presented.
Key factors affecting our performance, page 63

10.      Please discuss whether there are any material challenges related to
retaining and growing
         your existing customers that you have faced or expect to continue to
face. In this regard,
         we note that growth in subscription solutions revenue in fiscal year
2019 appears to have
         been primarily driven by the acquisition of new customers. Further, we
note your net
         revenue retention has fluctuated between negative and positive rates
for the periods
         presented. For additional context, please also disclose the average
fixed term of your
         existing non-cancelable enterprise contracts.
Key business metrics, page 63

11.      In your explanation of the computation of annual revenue run-rate, you
indicate that
         monthly recurring revenue includes contractual growth adjustments as
customers'
         businesses grow past contracted order thresholds. Please clarify
whether you include the
         actual adjusted fees once the customers' business has reached the
threshold or an
         estimated amount.
12.      In your explanation of the computation of average revenue per account
for accounts above
         the ACV threshold, please clarify the period you use to determine the
amount of
         customer-billed revenue and the allocated amount of partner and
services revenue
         included in the calculation.
13.      Please provide an analysis explaining how changes in your key business
metrics
         correspond to changes in revenues for the periods presented. For
example, address the
         decrease in both the number and the net retention rate of accounts
with ACV greater than
         $2,000 as of June 30, 2018 compared to March 31, 2018. Refer to the
Instructions to Item
         303(a) of Regulation S-K.
14.      You disclose the percentage of your ARR generated from accounts with
greater than
         $2,000 ACV for each period presented. Please also disclose the
percentage of ARR
         generated from customers on your Enterprise plan for each period
presented. In this
         regard, we note that as of December 31, 2019, such customers generated
"approximately
         half" of your ARR.
Liquidity and capital resources, page 72

offering will be sufficient to
         meet your working capital and capital expenditure needs and your debt
service obligations
         for at least the next 12 months. As it appears that you have

       resources will allow you to conduct planned operations and satisfy your
obligations, as
       well as the minimum dollar amount of funding required to remain in
business for at least
       the next 12 months. Also, highlight this risk in a separately captioned
