Is Thomasnet worth it? What a job shop gets from Thomasnet, Xometry and the RFQ marketplaces

Xometry’s partner agreement, updated April 15, 2026, says it pays partner shops within 40 days after their parts are accepted. The same agreement charges a partner $25,000 for each “Partner Prohibited Communication”, which includes contacting a customer you met through Xometry outside the platform, or tucking your own business card in the box. Thomasnet, meanwhile, lets any supplier claim a company profile for free and sells advertising on a monthly budget. Both have had the same owner since December 2021, when Xometry bought Thomas for $300 million.

Whether Thomasnet is worth it depends on which product you mean. The free profile is worth it, because it costs an afternoon and buyers do use the directory to build supplier lists. Paid placement is worth it only if you can trace RFQs back to it, and in the two head searches we checked, Thomasnet did not appear in Google’s top 10 at all. Marketplaces are worth it as a way to fill open machine hours, as long as you price for their terms and never mistake their customers for yours. Your own site is where a buyer learns your name and comes back.

What does each channel actually sell a job shop?

We read the supplier-facing pages and terms of four platforms on Oct. 26, 2026. Terms change; re-read them before you sign anything.

	Thomasnet	Xometry Partner Network	Protolabs Network	MFG.com	Your own site
What you get	A profile in a supplier directory; paid placement that “boosts your ranking in buyer search results”	Jobs matched to your capabilities; “No RFQs, no fees, no subscriptions”	“Pre-vetted, pre-sold orders”, $100 to $500,000	RFQs from buyers that you quote	Inquiries from buyers who found you
What it costs	Free profile; paid Verified subscription and advertising; “Pay only when potential buyers engage with your profile”	Free to join; FastPay early payout carries “a nominal fee”	Free to join	“Pay per RFQ or go Premium for unlimited opportunities”	Your time, hosting and promotion
Who sets the price	You, with the buyer	The agreement says you make parts “for the price(s) provided by Partner in its quote” as accepted in the work order	Not stated; the page says “We handle the negotiations”	You, in your quote	You
When you get paid	Between you and the buyer	Within 40 days after parts are accepted	Not stated on the partner page	Between you and the buyer	Between you and the buyer
Who talks to the customer	You	Only through the platform (“Direct Comms”)	Protolabs Network handles “all customer communication”	You, after the match	You

Xometry’s partner page says you accept only the jobs “that fit your schedule, capabilities, and pricing goals”, while its agreement refers to the price in the partner’s quote; we report both because both are on Xometry’s own pages. Protolabs Network’s partner page does not publish payout timing or who sets prices, so we left those cells as “not stated” rather than guess.

Who ranks when a buyer searches for a shop?

Directories and marketplaces both pitch themselves as the place buyers look. We checked two searches, not a broad sample: Ahrefs’ snapshots of the US results pages for “cnc machining services” (3,200 searches a month, crawled Oct. 23, 2026) and “custom injection molding” (1,600 a month, crawled Oct. 21, 2026).

	cnc machining services	custom injection molding
Online instant-quote services in the organic top 10	6: Xometry, Protolabs, SendCutSend, JLCCNC, PCBWay, PartsBadger	4: Protolabs, Xometry, PCBWay, Ponoko
Independent shops and molders in the organic top 10	1: American Micro Industries	3: The Rodon Group, Rapid Molding, Thogus
Other organic results	1: a Facebook page	1: a YouTube video
Map pack	3 local machine shops	3 local molders
Thomasnet	Not in the top 10	Not in the top 10

Two searches cannot tell you how directories do across every buyer query, and they do show up on list-style searches. In our own checks from southwest Ohio on Oct. 26, 2026, a Thomasnet list page ranked on page one for “injection molding companies”, as our guide to what buyers search before they pick a molder logs, and thomasnet.com ranked for “conveyor manufacturers”, in the page-one log of our manufacturing SEO study. On the two phrases above, the kind a buyer types with a part to make, the platforms that sell finished parts held the top of the page and the directory was absent. If you are paying a directory for visibility, that is the comparison to keep in mind. Page one also shifts by day and location; our guide to what OEM buyers search for a machine shop logged its own check of the first query on Oct. 26, 2026, from Ohio, with a slightly different mix.

On both pages, the map pack’s three slots went to local businesses with Google Business Profiles, and a profile costs nothing.

Is Thomasnet worth it for a job shop?

Thomas makes a big claim about reach. Its supplier pages cite more than 2.2 million registered buyers, “7,500 New Users Join Monthly” and “over 500,000 industrial suppliers”, and say “Sixty-six percent of buyers visit with a specific purchasing need.” Its advertising page promises “25x More Buyer Evaluations with Premium Placement” without saying 25 times what.

Our position is to claim and complete the free profile, because the cost is an afternoon. List your certifications, equipment and part size range there exactly as on your own site. Then treat paid placement like any other ad buy. Before you renew, ask Thomas for engagement data in your categories, and add a “How did you hear about us?” field to your RFQ form, as HEI Precision’s request-for-quote form does; our RFQ-to-quote playbook covers the rest of that form. If you cannot connect a quote to the spend after two quarters, drop to the free tier.

Know what else Thomas sells. Its homepage lists “Website Design & SEO” and “Digital Marketing & PPC” among its business services, and the footer of Midway Swiss Turn’s site, a 2026 Modern Machine Shop Top Shop, reads “Site created by Thomas Marketing Services.” Buying those services is fine, as long as you are clear which product you are paying for and how each one will be measured.

When does a marketplace make sense?

A marketplace makes sense when machines sit idle. Plastics Technology’s 2026 Top Shops benchmark, published Oct. 21, 2026, found average capacity utilization of 62% at the honored molders and 61% at everyone else, and the magazine noted neither figure was high. Metalworking shops are adding machines in 2026. AMT’s August figures, reported by Manufacturing Dive, put US manufacturing technology orders up 36.3% from a year earlier, which means more new machine hours that shops will need to fill.

A marketplace fills those hours without a salesperson. Protolabs Network says partners “only have to focus on producing custom parts.” Xometry says its jobs are matched to your capabilities and that “JCP, CMMC, AS9100, and ITAR shops earn 6X more on average,” a figure it does not explain.

Run it with rules, and write them down before the first job:

• Set a ceiling on the share of shop hours that go to marketplace work, and review it monthly.
• Price for the payment terms. Forty days after acceptance is a cost of carrying the job.
• Read the inspection and delivery clauses. Xometry’s agreement lets its examiner reject nonconforming parts, and on expedited or DPAS-rated work orders that ship late it lets Xometry deduct “up to the total amount of the Work Order.”
• Treat marketplace jobs as practice in new materials and tolerances. By design, you will not get the customer from them.

Giving up the customer is the whole trade. Xometry’s agreement bars partners from marketing to customers they learn of through the platform, and Protolabs Network handles customer communication itself. A shop that does all of its new work this way has no customer list of its own to sell to, or to sell with the business.

How do these compare with your own site?

Your website is the only channel where the buyer learns your name, sees your equipment and sends the next RFQ directly. It does the slow work the others skip: it ranks for your process and town, it supports your Google Business Profile, and it gives an engineer something to forward to a buyer. Our teardown of job shop capabilities pages shows what to put on it, and our Google Ads guide for job shops shows how to buy clicks to it without bidding against the platforms.

In your industry

Metals and machining. CNC is where the platforms are strongest: six of eight organic results for “cnc machining services” were online services. Compete on what they do not show, such as certifications, named machines and repeat production, and use the marketplace for overflow.

Plastics and rubber. The molding results page we checked still left room for independent molders, three of eight organic results. Protolabs Network asks molding partners to build molds or mold parts in-house and lists certifications such as ISO 9001 and ISO 13485; a molder with a cleanroom or medical certification has more to gain from its own site than from a marketplace queue.

Industrial machinery and equipment. Larger fabricated and machined assemblies fit RFQ-style platforms where you quote, like MFG.com, better than instant-quote engines. Your own site still has to carry the size and weight ranges that get you on a buyer’s list.

What to do Monday

1. Claim your free Thomasnet profile and make it match your website, certification by certification.
2. Add a “How did you hear about us?” field to your RFQ form and log the answer on every quote.
3. If you use a marketplace, write your ceiling and pricing rules for it now, and re-read the partner agreement each time it is updated.
4. Search your top three processes in Google and note who ranks. Those sites are your real competition for new buyers, and none of those slots can be bought from a directory.
