<p style="margin-top:6px;margin-bottom:0px"><font style="font-family:times new roman" size="2"><i>Business Description </i></font></p>
<p style="margin-top:6px;margin-bottom:0px; text-indent:4%"><font style="font-family:times new roman" size="2">We are a leading provider of on-demand supply chain management solutions, providing prewired, proven integrations and comprehensive retail
performance analytics to thousands of customers worldwide. We provide our solutions through the SPS Commerce platform, a cloud-based software suite that improves the way suppliers, retailers, distributors and other customers manage and fulfill
orders. We deliver our solutions to our customers over the Internet using a Software-as-a-Service model and derive the majority of our revenues from thousands of monthly recurring subscriptions from businesses that utilize our solutions. </font></p>

<p style="margin-top:6px;margin-bottom:0px; text-indent:4%"><font style="font-family:times new roman" size="2">The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles
generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, these condensed consolidated financial statements do not
include all of the information and notes required by GAAP. We have included all normal recurring adjustments considered necessary to give a fair statement of our financial position, results of operations and cash flows for the interim periods shown.
Operating results for these interim periods are not necessarily indicative of the results to be expected for the full year. The December 31, 2012 balance sheet data was derived from our audited financial statements at that date. For further
information, refer to the consolidated financial statements and accompanying notes for the year ended December 31, 2012 included in our Annual Report on Form 10-K as filed with the Securities and Exchange Commission on March 6, 2013.

<p style="margin-top:6px;margin-bottom:0px; text-indent:4%"><font style="font-family:times new roman" size="2">
Preparing financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets
and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. </font></p>

<p style="margin-top:6px;margin-bottom:0px; text-indent:4%"><font style="font-family:times new roman" size="2">During the three months ended March 31, 2013, there were no material changes in our significant accounting policies. See Note A to
the consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2012, as filed with the Securities and Exchange Commission on March 6, 2013, for additional information regarding our
significant accounting policies. </font></p>

<p style="margin-top:6px;margin-bottom:0px; text-indent:4%"><font style="font-family:times new roman" size="2">
Effective July 1, 2012, we adopted an employee stock purchase plan which allows participating employees to purchase shares of our common stock at a discount through payroll deductions. The plan is
available to all employees subject to certain eligibility requirements. Participating employees may purchase common stock, on a voluntary after tax basis, at a price that is the lower of 85% of the fair market value of one share of common stock at
the beginning or end of each stock purchase period. The plan consists of two six-month offering periods, beginning on July 1 and January 1 of each calendar year. A total of 1.2 million shares of common stock are reserved for issuance
under the plan. </font></p>
<p style="margin-top:12px;margin-bottom:0px; text-indent:4%"><font style="font-family:times new roman" size="2">As of March 31, 2013, we have withheld approximately $271,000 from employees participating in the plan
for the offering period that began on January 1, 2013 and a total of approximately 1.2 million shares were available for future purchases under the plan. </font></p>
<p style="margin-top:12px;margin-bottom:0px; text-indent:4%"><font style="font-family:times new roman" size="2">
For the three months ended March 31, 2013, we recorded approximately $93,000 of stock-based compensation expense associated with the employee stock purchase plan.
The fair value was estimated based on the market price of our common stock at the beginning of the offering period, which was $37.27 per share, and
using the Black-Scholes option pricing model with the following assumptions: </font></p>

Operating results for these interim periods are not necessarily indicative of the results to be expected for the full year. The December 31, 2012 balance sheet data was derived from our audited financial statements at that date. For further
