I, Bradley A. Cleveland, hereby authorize and designate each of Archie C. Black,
Kimberley K. Nelson, Andrew G. Humphrey, Jonathan R. Zimmerman, Matthew Kuhn,
Ryan R. Miske, James R. DeBuse, Andrew V. Tran, Kassendra D. Galindo, Brook T.
Nuernberg, Julie M. Regnier and Lauren Graff signing singly, as my true and
lawful attorney-in-fact to:

     (1)  execute for and on my behalf, in my capacity as an officer, director
and/or greater than 10% stockholder of SPS Commerce, Inc. (the "Company"), Forms
ID, 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;

     (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, 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 or any such
attorney-in-fact's substitute or substitutes 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 Forms ID, 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 of Faegre Baker Daniels LLP,
(ii) an employee of Faegre Baker Daniels LLP or (iii) an employee of SPS
Commerce, Inc., 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 may have been granted by me
in connection with my reporting obligations, if any, 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 7th day of November, 2012.

/s/ Bradley A. Cleveland
