LIMITED POWER OF ATTORNEY
FOR SECTION 16 REPORTING OBLIGATIONS

I, Archie Black, hereby authorize and designate each of Andrew G.
Humphrey, Jonathan R. Zimmerman, Ryan R. Miske, Andrew V. Tran, Brian E.
Jacobson, Miranda S. Hirner, Thomas P. Trier, Mary A.L. St. Marie, Amra Hosa and

Victoria A. Larson, signing singly, as my true and lawful attorney-in-fact to:

(1)	execute for and on my behalf, in my capacity as director of
SPS Commerce, Inc., a Delaware corporation (the "Company"), the Form ID and
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;

(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 Form
3, 4 or 5 and timely file such form with the Securities and Exchange Commission,

any stock exchange or similar authority, and the National Association of
Securities Dealers; 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 substitutes 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 the 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.

This Limited Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file Forms 3, 4 or 5 with respect to the
undersigned's holdings of and transactions in securities issued by the
Company, unless earlier revoked by the undersigned in a signed writing
delivered to each of 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, or (ii) an employee of Faegre Baker Daniels LLP, this Limited Power of
Attorney shall be automatically revoked solely as to such individual,
immediately upon such cessation, without any further action on the part of the
undersigned.

IN WITNESS WHEREOF, the undersigned has executed this Limited Power of
Attorney as of this 30th day of March, 2015.


Signed and acknowledged:
