Scientist.com publishes no single price list, so we assembled one from its own pages. Supplier registration and quoting are free. Facilitated sales carry a variable transaction fee whose percentage is not published. SciPay early payment costs 2.00% to 3.00%, plus 0.75% on non-USD invoices. Optional marketing subscriptions run $5,040 to $28,800 per year. Buyer-side enterprise terms are not published. For comparison, BioBridgeX (which publishes this page) charges suppliers a flat 2% success fee.
Why this page exists: the fee information is scattered
Search for Scientist.com pricing and you will not land on a price page. The numbers exist, but they sit in five separate places: the public homepage, a supplier backoffice FAQ, the supplier agreement, a three-page PDF rate card dated May 16, 2025, and a SciPay payments page. As far as we can tell, nobody has pulled them into a single reference. This page does that, with the source named next to every figure.
Two ground rules. First, every number here was pulled from a Scientist.com property (scientist.com or backoffice.scientist.com) in August 2026; where a figure is not public we write "not published" instead of guessing. Second, disclosure: this page is published by BioBridgeX Ltd, a London-based marketplace that competes with Scientist.com. The Scientist.com facts below stick to the company's own published words, and the comparison section at the end is kept separate from the reference material.
What buyers pay: not published, and folded into the quote
Scientist.com's homepage describes a network of "6,000+ Global Providers" across "1,000+ Scientific Categories" with "18M+ Off-the-Shelf Products". What it does not carry is a buyer price list. Enterprise buyers access the platform through private, company-branded marketplaces under negotiated agreements, and those terms are not published anywhere we could find.
The mechanics matter more than the label. Per the supplier agreement, "Quotations issued by Supplier to Client will include the Transaction Fee in the total price quoted." In plain terms, the platform's fee reaches the buyer inside the supplier's price rather than as a separate line item. The backoffice FAQ adds that the transaction fee and payment terms "can vary by request and marketplace partner", so the effective cost of the platform can differ from one client request to the next. A buyer modeling total study cost should know the fee is in the price, just not broken out.
The Scientist.com transaction fee: variable, set per request
The supplier side starts free. The backoffice FAQ states there are "no fees to register for an account, create a profile, receive requests or submit price quotes." Money changes hands when a sale is facilitated through the platform.
The supplier agreement (written in the name of Assay Depot, Scientist.com's legal entity) defines the fee base as "the total payment received from the Client less any service-related shipping charges, applicable taxes or credit card transaction fees." The percentage itself is not published. It is disclosed inside each client request, and once specified for that request it cannot be changed without the supplier's consent. Between requests, the company "reserves the right to change or modify the Transaction Fee at any time, in its sole discretion."
Payout timing is contractual too: funds are transferred to the supplier within 15 days of Scientist.com receiving the client's payment, and payment to the supplier is conditional on the client actually paying. Read the fee terms on every individual request before quoting rather than assuming last quarter's rate still applies.
SciPay rates: what faster payment costs
SciPay is Scientist.com's payment and invoicing program, and its rates are among the few numbers the company publishes directly. The cost scales with how quickly the supplier wants cash: NET60 costs 2.00% of the invoice, NET45 costs 2.50%, and NET30 costs 3.00%. Invoices up to $25,000 are approved automatically, with what the page calls fair, flexible terms on larger ones.
Two more published details. A 0.75% foreign transaction fee applies to invoices in currencies other than USD, and the platform supports eight currencies: USD, GBP, EUR, SEK, CHF, CNY, JPY, and CAD. For a European CRO invoicing in EUR and wanting 30-day payment, the published SciPay stack is 3.75% before the unpublished transaction fee enters the math.
The Scientist.com rate card: supplier subscriptions
The clearest published pricing sits in the Marketing Services Rate Card, a PDF hosted on backoffice.scientist.com (effective May 16, 2025, Rev 1.6, marked "pricing subject to change without notice"). It lists four supplier subscription plans, available only to registered suppliers, priced below.
These are visibility packages, not access fees. A supplier can receive requests and submit quotes without one. The backoffice FAQ describes the paid options as marketing opportunities: sponsored ads, supplier spotlights, newsletters, webinars, and podcasts. With 6,000+ providers listed by the company's own count, search visibility has value, and the subscriptions are how the platform prices it. Whether that spend earns its keep depends on how many requests convert in your category.
- Essential: $420 per month, $2,520 per 6 months, $5,040 per year (newsletter ad requires an annual commitment)
- Plus: $630 per month, $3,780 per 6 months, $7,560 per year
- Premium: $1,150 per month, $6,900 per 6 months, $13,800 per year
- Elite: $28,800, sold annually only
A la carte services, bundles, and annual marketing plans
The same rate card prices individual marketing services. A selection, verbatim from the May 2025 card: PRO Webinar Production and Promotion at $16,500, Survey Eblast at $12,500, Dedicated Eblast at $10,000, Targeted Eblast at $7,000, Virtual Demo at $7,000, Video Interview at $6,000, Podcast Interview at $4,500, Newsletter Banner Ad at $3,000, Sponsored Blog at $3,000, and co-branded press releases at $2,500 to $5,000 depending on distribution.
Pre-set bundles run from $9,000 (Introduction to Advertising) to $62,900 (Technology Content Pack). Annual Marketing Plans commit a supplier to a 12-month spend level in exchange for bonus credits: Bronze at $25,000+ (worth $27,000 in spend value), Silver at $35,000+ ($39,200), Gold at $45,000+ ($52,900), and Platinum at $55,000+ ($66,900).
The card also prices platform tooling. VERIF.i lab pre-assessments cost $14,000 per supplier or site for human biological samples, animal welfare, or chemistry, manufacturing and controls, and $16,000 for the two-day Good Laboratory Practices assessment. Site integration (single sign-on, CRM, and COMPLi) runs $15,000 annually. The e-commerce solution with AI chatbot is listed as "Please Inquire".
What Scientist.com supplier costs can add up to
Here is the straight arithmetic for a supplier weighing the platform. Take a CRO awarded a $100,000 study. The transaction fee applies at a percentage that is not published, so call it X% of roughly $100,000 less shipping, taxes, and card fees. If the CRO wants payment at NET30 through SciPay, add 3.00% ($3,000). If it invoices in EUR or GBP, add 0.75% ($750). If it also runs a Premium subscription for visibility, that is $13,800 for the year regardless of how many projects it wins.
Everything in that stack except X is published. X is the number to get in writing on each request before quoting, because the agreement makes it binding per request once specified. A supplier comparing platforms should ask the same question everywhere: what do I pay, when do I pay it, and does anything charge me before I win work?
What is not published, stated plainly
For completeness, the list below covers what we could not find on any public Scientist.com property in August 2026.
None of this is unusual for enterprise procurement software, and Scientist.com publishes more supplier-side detail than most sourcing platforms. A public rate card and public SciPay rates are genuinely useful, and credit is due for both. The gap that matters most is the transaction fee itself: it is the one recurring cost tied directly to winning work, and the one number a supplier cannot model in advance.
- The transaction fee percentage: set per request, stated to vary by request and marketplace partner, no public rate anywhere
- Buyer-side pricing: enterprise marketplace terms are negotiated, not published
- E-Commerce Solution + AI Chatbot: listed as "Please Inquire" on the rate card
- Virtual Event, Summit or Mini-Series pricing: listed as "Please Inquire"
- How fee levels differ across partner-branded marketplaces: stated to vary, values not given
CRO marketplace fees comparison: three models
Sourcing platforms in this space cluster into three fee models. Scientist.com uses a variable, platform-facilitated transaction fee included in the quoted price, plus optional paid visibility. Free directories cost nothing but stop at discovery: no RFQ workflow, no quote management, you chase every vendor yourself. BioBridgeX (our platform, so weigh this paragraph accordingly) uses a flat, published success fee: suppliers pay 2% only when a project is awarded and paid, buyers use it free, and buyers contract with and pay suppliers directly, so no payment routes through the platform and the 2% is the only fee.
Each model fits a different buyer. If your procurement team needs deep systems integration and a managed supply chain across thousands of vendors, Scientist.com's enterprise model is built for exactly that, and its scale (6,000+ providers by its own count) is real. If you are a biotech founder or program lead who wants transparent economics and direct supplier relationships from IND-enabling work through CMC and manufacturing, a flat-fee neutral marketplace keeps the math simple: the fee is 2%, it is public, and it exists only when you award work. BioBridgeX runs no labs of its own and its public vendor directory holds 260+ profiles, smaller than Scientist.com's network and open for anyone to inspect.
Whichever model you choose, run the numbers yourself. Browse a free vendor directory, generate a structured RFP, and put the responses side by side in a quote comparison grid before committing to any platform's economics. Ready to price a study?
