POWER OF ATTORNEY

	I, Jamie Thingelstad, hereby authorize and designate each of Jonathan R.
 Zimmerman, Kareem Tawfic, Ryan Miske, Christine G. Long, Sabra Drummond, Amra
 Hoso, Kimberly K. Nelson and Brian Senger signing singly, as my true and
 lawful attorney-in-fact to:

(1) execute for and on my behalf, in my capacity as an officer and/or director
 of SPS Commerce, Inc., a Delaware corporation, (the "Company"), Form ID or
 Forms 3, 4 and 5 in accordance with Section 16(a) of the Securities Exchange
 Act of 1934 (the "Exchange Act") and the rules and regulations promulgated
 thereunder and other forms or reports on my behalf as may be required to be
 filed in connection with my ownership, acquisition, or disposition of
 securities of the Company, including Form 144;

(2) do and perform any and all acts for and on my behalf which may be necessary
 or desirable to complete and execute any such Form ID or Forms 3, 4 or 5 and
 timely file such form with the Securities and Exchange Commission and any
 stock exchange or similar authority; and

(3) take any other action of any type whatsoever in connection with the
 foregoing which, in the opinion of such attorney-in-fact, may be to my
 benefit, in my best interest, or legally required of me, it being understood
 that the statements executed by such attorney-in-fact on my behalf pursuant to
 this Power of Attorney shall be in such form and shall contain such terms and
 conditions as such attorney-in-fact may approve in such attorney-in-fact's
 discretion.

I hereby further grant to each such attorney-in-fact full power and authority
 to do and perform any and every act and thing whatsoever requisite, necessary,
 or proper to be done in the exercise of any of the rights and powers herein
 granted, as fully to all intents and purposes as I might or could do if
 personally present, with full power of substitution or revocation, hereby
 ratifying and confirming all that such attorney-in-fact, or such attorney-in-
fact's substitute or substitutes, shall lawfully do or cause to be done by
 virtue of this Power of Attorney and the rights and powers herein granted.  I
 hereby acknowledge that the foregoing attorneys-in-fact, in serving in such
 capacity at my request, are not assuming, nor is the Company assuming, any of
 my responsibilities to comply with Section 16 of the Exchange Act.

This Power of Attorney shall remain in full force and effect until I am no
 longer required to file Form ID or Forms 3, 4 and 5 with respect to my
 holdings of and transactions in securities issued by the Company, unless
 earlier revoked by me in a signed writing delivered to the foregoing
 attorneys-in-fact.  Notwithstanding the foregoing, if any such attorney-in-
fact hereafter ceases to be at least one of the following: (i) a partner or
 employee of Faegre Drinker Biddle & Reath LLP or (ii) an employee or officer
 of SPS Commerce, Inc., then this Power of Attorney shall be automatically
 revoked solely as to such individual, immediately upon such cessation, without
 any further action on my part.

I hereby revoke all previous Powers of Attorney that have been granted by me in
 connection with my reporting obligations under Section 16 of the Exchange Act
 with respect to my holdings of and transactions in securities issued by the
 Company.

IN WITNESS WHEREOF, I have caused this Power of Attorney to be duly executed as
 of this 28th day of May, 2024.

/s/ Jamie Thingelstad
