We supply commercial software to federal agencies.

Mainstay Supply Co LLC is a veteran-owned small business reseller. When an agency needs a specific license, renewal, or subscription and cannot buy it from the publisher directly, we bridge that gap. We quote fast, we carry the registrations, and the publisher delivers and supports the product exactly as they always have.

Product supply

We supply software an agency has already chosen.

Mainstay supplies commercial software, licenses, and renewals when a requirement calls for a specific product. Send the requirement, we return a compliant quote, and the publisher delivers the license and support directly. Useful when the publisher is not registered in SAM, or is too large to compete for a small business set-aside.

Set-Aside Eligible

SBA-certified veteran-owned small business. Eligible for small business and veteran-owned set-asides.

Registered and Ready

Active SAM registration with UEI and CAGE code. Quotes on your terms, invoiced on your schedule, compliant with your clauses.

Authorization Before Quote

Where a publisher requires written authorization to quote its product, we obtain it before quoting, so delivery and support come from the source.

Fast Turnaround

License renewals and brand-name requirements move on short deadlines. We return quotes in days, not weeks.

For software publishers

Government wants your product. Sometimes it can't buy it from you.

Federal buyers post requirements naming specific products every day. If your company is not in SAM, or the buy is set aside for small business, or the renewal never reached your sales team, that revenue goes to whoever holds the paperwork. That is where we come in.

You keep your price

You quote us your standard channel price. We carry the federal contract, the registrations, and the compliance work.

Two documents, one deal

A reseller authorization letter and a quote. That is all we need from you to compete for a live federal requirement.

No channel commitment

We work deal by deal. No distribution agreement, no minimums, no exclusivity. If a requirement names your product, we call you.

You keep the customer

Delivery, support, and the renewal relationship stay with you. We are the contract vehicle, not a middle layer on your product.

Heard from us about a live requirement? The deadline is usually days away. Reply to the email or call back the same day and we can still make it.
How it works

Three steps.

01

Send the requirement

An RFQ, a renewal notice, or a product name and quantity. That is all we need to start.

02

We return a compliant quote

Backed by manufacturer authorization and priced through the publisher's own channel.

03

The publisher delivers

Licenses, keys, and support come direct from the maker. We handle the contract side.
