Register as a City Vendor

Anyone providing goods or services to the City must register as a vendor to receive payments. Vendor registration is a two-step process.

The City of Lenexa has implemented an electronic accounts payable solution to process vendor payments through Paymode-X. This program enhances payment security, reduces the risk of fraud, and maximizes financial efficiency. If you do not register with Paymode-X, payments will be issued by paper check.

Register online

Step 1.Register with Lenexa Vendor Self-Service Portal

  • Manage your vendor account information (including addresses and W-9s).
  • View payment details and account history.

You must upload a completed Form W-9(PDF, 162KB) to your account. The Internal Revenue Service requires a W-9 to confirm a vendor’s taxpayer identification number.

Detailed registration instructions can be found in the Vendor Registration Instructions Guide(PDF, 2MB).

Frequently asked questions

What is the City's sales tax exemption number?

Our sales tax exemption number is KSB2C55NQW. If your company requires a certificate on file, contact the Finance Department at 913.477.7540.

Please note: K.S.A. 79-3606 (b) statute exempts all sales of tangible personal property and services, including the renting or leasing of tangible personal property, purchased directly by the State of Kansas or a political subdivision thereof, and used exclusively for state or political subdivision purposes.

Can the City provide a tax exempt number or letter to prove status as a tax-exempt organization?

The IRS does not provide a tax exempt number, however we can use our federal identification number for identification purposes. In addition, we have an IRS tax exempt letter that describes our exemption from federal income tax and the Internal Revenue Code sections that pertain to deductible contributions and income exclusions.

For more information, see the IRS explanation of tax-exempt status or contact the Finance Department at 913.477.7540.
