How to Price and Launch an Authentication Service as a New Revenue Line

By YourGrowthPartner  |  April 2026  |  9 min read

If you are already authenticating items for your own resale business, you are sitting on an unexploited revenue opportunity. The expertise, equipment, and credibility you have built to verify your own inventory can be packaged as a service for sellers, private buyers, individual collectors, and partner platforms who need that same expertise but do not have it in-house.

Authentication as a standalone revenue line is not a new idea. The RealReal, Entrupy, and Authenticate First have all built significant businesses around it. But you do not need to be a platform at scale to make it work. Any resale business with genuine category expertise and consistent process can launch an authentication service and generate meaningful income from it within 30 to 60 days.

This guide covers how to define your service tiers, cost and price them correctly, build the trust signals that make buyers willing to pay, and pilot the service before committing to full infrastructure.

Step 1: Define Your Service Tiers

Authentication is not a single service. The depth of verification a buyer needs for a 500 AED bag is different from what they need for a 50,000 AED watch. Tiering your service lets you serve multiple customer types, price appropriately for the work involved, and upsell naturally.

Tier 1: Visual Authentication

This is your entry-level service. The client submits photos (typically 20 to 30 images of specific reference points) and your expert reviews them remotely. You are checking stitching, hardware, font, date codes, tags, lining, and overall construction quality against authenticated examples from your reference library. The output is a written authentication report with a pass or fail determination, and a brief explanation of the key indicators reviewed.

This tier is appropriate for items under roughly 3,000 AED and for buyers or sellers who need a quick, credible check before proceeding with a transaction. It requires the least time (typically 30 to 60 minutes per item for an experienced authenticator) and has the lowest overhead.

Tier 2: Full In-Person Authentication

The client ships the item to you (or brings it in person) and you conduct a hands-on examination. In-person authentication allows you to check elements that photos cannot capture: hardware weight, leather texture and smell, interior seam quality, and the subtle tactile details that separate originals from high-quality fakes. You produce a detailed written certificate with photos documenting the key authentication points.

This tier is appropriate for mid-to-high value items where the buyer needs a defensible, documented result. It takes longer (typically 2 to 4 hours depending on complexity), requires physical handling and return shipping, and carries higher liability, which is reflected in the price.

For in-person authentication appointments, condition assessment typically runs in parallel with authentication. Both processes inspect the same physical item, and the condition grade directly affects how the item is priced and listed. Implementing a standardized grading taxonomy before you scale your authentication service means every item that passes through your hands gets a consistent condition grade alongside the authentication verdict. Our guide to designing a product condition filter for pre-owned marketplaces covers how to build the grading taxonomy and inspector checklist that makes this dual-assessment process consistent and scalable.

Tier 3: Authentication with Provenance and Documentation Review

This is your premium service. In addition to the full in-person authentication, you review any accompanying paperwork: receipts, box, dustbag, guarantee cards, and service records. You verify that the serial numbers on the item match the accompanying documents and prepare a comprehensive provenance report. For watches, this might include movement inspection. For jewellery, gemstone and metal testing.

This tier is appropriate for very high-value items (typically 20,000 AED and above) where the buyer needs the most thorough possible verification before committing to a significant purchase, or where the item is being sold with a formal provenance claim.

Step 2: Cost Each Tier Accurately

Pricing without understanding your costs is how authentication services end up losing money on complicated items. Before setting prices, cost each tier properly.

For each tier, calculate the following components.

• Labor: How many hours does each tier take, and what is the hourly cost of the authenticator (whether that is your own time or a specialist you hire)?
• Overhead allocation: Equipment, subscriptions to authentication databases and reference libraries, photography equipment, certificate printing or digital delivery infrastructure.
• Shipping and insurance: For Tier 2 and 3, you are handling items worth thousands. Insured two-way shipping plus any handling costs need to be priced in or charged separately.
• Liability provision: If you issue a certificate and you are wrong, what does that cost you? Build a small percentage into your price as a reserve against disputes, even if you are confident in your accuracy.

Once you have a total cost per tier, apply a 2x to 3x margin for your standard pricing. This is not excessive for an expertise-based service. Authentication requires years of knowledge accumulation and carries real reputational risk. Your pricing should reflect that.

Step 3: Choose Your Pricing Models

Authentication services can be priced in several ways depending on your client type. You do not need to choose just one. Most authentication businesses use different models for different client segments.

Fixed fee per item

The simplest model. A clear per-item fee for each tier. This works for individual buyers and sellers who are submitting items one at a time. It is easy to communicate, easy to quote, and easy to invoice. Example structure: Tier 1 visual at 150 AED, Tier 2 in-person at 450 AED, Tier 3 provenance at 850 AED.

Tiered fee by brand or value

Some authenticators charge higher fees for brands or item categories that require more specialist knowledge or carry higher risk. A Tier 2 authentication of a Chanel 2.55 and a Tier 2 authentication of a vintage Patek Philippe are not the same job. Tiering by brand or price range allows you to price the harder work appropriately without undercharging on complex categories.

Subscription for sellers

If you have consignment partners or marketplace sellers who submit items regularly, a monthly subscription model makes sense. For a fixed monthly fee, they get a set number of authentications per month with a per-item fee for additional volume. This creates recurring revenue for you and predictable cost for them. A typical structure might be 2,500 AED per month for 10 Tier 1 authentications, with Tier 2 available at a discounted rate for subscription holders.

For consignment partners using the subscription model, the authentication service is most effective when it sits within a formal consignment agreement that defines how authentication outcomes affect payout rates and listing decisions. A consignor whose item fails authentication needs to know in advance what happens next. Our guide to setting up consignment program contracts and payouts covers how to structure the intake agreement, payout tiers, and dispute resolution process in a way that integrates cleanly with your authentication workflow.

Percentage of sale for consignment partners

For partners who only want to pay when a sale happens, a percentage of the final sale price as an authentication fee can work. This aligns your interests (authenticate accurately so items sell) and removes upfront cost friction for partners. The trade-off is that your revenue is variable and slower. A typical rate is 1 to 3 percent of the sale price, depending on category and volume.

Step 4: Build the Trust Signals That Drive Purchases

The quality of your authentication certificates and the credibility of your process are what clients are actually paying for. Invest in making both as strong as possible from day one.

Authentication certificates

Your certificate should include: a unique reference number, the item description and key identifiers (brand, model, color, hardware, serial/date code), the authentication outcome (Authentic, Not Authentic, or Inconclusive), the date of authentication, the name and credentials of the authenticator, and key photos of the authentication reference points. A QR code linking to a digital version that clients can share is a worthwhile addition.

Process documentation

Publish a detailed page on your website showing exactly how you authenticate. Not a vague paragraph, but a visual walkthrough of what you check, what tools you use, and what the output looks like. This is your most powerful sales tool for convincing first-time clients that your process is worth paying for. Clients who can see the process have higher conversion rates and fewer disputes post-authentication.

Guarantee policy

Define clearly what happens if you authenticate an item as genuine and it later proves to be a fake. A guarantee that provides a full fee refund in the event of a verifiable authentication error builds confidence without creating unmanageable financial exposure. If you are confident in your accuracy, this policy costs you very little in practice but dramatically increases buyer trust.

Step 5: Run a Pilot Before Building Infrastructure

Do not spend three months building a website, a CRM workflow, and a certificate system before you have validated that people will pay for this service. Run a manual pilot first.

Identify 5 to 10 people in your existing network who regularly buy or sell pre-owned luxury items and offer them authentication at your proposed pricing. Document every authentication manually. Use a simple Google Form for intake, a Word document for your certificate, and invoicing via your existing payment method. This is not scalable, but it is not supposed to be yet.

After your first 10 to 20 authentications, you will know: whether clients value the service at your price point, which tier gets the most demand, what the most common intake friction points are, how long each tier actually takes vs your estimate, and what questions or objections you need to address in your marketing.

That data is worth more than any market research. Use it to refine your pricing, your process documentation, and your go-to-market materials before you invest in infrastructure.

Key Metrics

• Attach rate: What percentage of your listed or consigned items are being authenticated through your service? A high attach rate means buyers trust the service and sellers see value in it. A low rate suggests pricing or awareness issues.
• Revenue per authentication: Track average revenue by tier. This tells you which tier is driving the most value and whether your pricing is being accepted by the market.
• Fraud rate: How many items that you authenticated as genuine were later disputed? A zero or near-zero fraud rate is your most important credibility metric. Track it from day one.
• Chargebacks avoided: For items sold with your certificate, track whether you see lower chargeback or dispute rates compared to items without one. This is a compelling selling point when pitching consignment partners or marketplaces.

Buyers who purchase with your authentication certificate are significantly more likely to return, because they know what they are getting. That trust is exactly what a loyalty program is designed to compound.

Timeline

You can launch a pilot authentication service in under a month: one week to define tiers, costs, and pricing; one week to create your certificate template and process documentation; one week to reach your pilot clients and complete your first authentications; one week to invoice, collect feedback, and refine. After 30 to 90 days of piloting, you will have enough data to decide whether to invest in building out the full infrastructure, and what that infrastructure should look like.
