Purchasing

Vendors must register on the RMEPS website to submit your solicitations electronically. If you need assistance, please contact the RMEPS Vendor Support department at 1-800-835-4603, option 2.

The Purchasing Division provides a centralized source for pricing, sourcing, quotations, order placement, vendor contact and general problem solving. It is the responsibility of the Purchasing Division to buy the right quality, in the right quantity, at the right time, from the right supplier at the right price.

To accomplish this, we must know the marketplace, determine the best way to acquire materials and services, and develop bid documents that are consistent with state laws, county policies and standard procurement practices. Purchasing oversees all of the bid processes to ensure compliance with these standards. For information regarding about the County’s purchasing process, please refer to How to do Business with the County.

Vendor and Bid Information


Arapahoe County always welcomes new vendors to register and join our list of quality suppliers for goods and services. If you are a vendor looking to do business with the County, check out current bid opportunities or contact our office. 

You are encouraged to complete the Vendor Evaluation form based on the product or service you provide. This information will contribute to the success of future purchases.

For more information on the Electronic Bid Submission (EBS) process, refer to the EBS for Vendors guide.

Purchases are accomplished by issuance of a numbered purchase order, authorized by the purchasing agent. Professional services are secured by contract and supported by issuance of a purchase order. Upon receipt of a correctly initiated order and invoice, the department receiving the product will authorize payment. Progress payments for construction projects are authorized by the project manager. Discount terms are highly encouraged. The average payment period by the Finance Department is 30 days.

The Purchasing Division also gives a workshop for vendors every quarter on the purchasing process overview. This presentation will help to explain the purchasing process, laws and regulations, what the County purchases, methods of procurement, the evaluation process, and awarding the contract. The Sample Request for Proposal and Sample Addendum that are referenced in the presentation will help in aiding you to understand the overall process.
