Sell Custom Shirts Online: Side Hustle Guide for Fitness Businesses

Selling custom shirts online for a fitness business means uploading your logo, setting a retail price, and sharing a link. Your community visits the link, picks their size, pays the retail price, and their shirt arrives within about a week. You earn the margin on every order without touching a single shirt. This guide covers how to set up the link, how to drive the first sales, and what to expect in terms of ongoing income.

How to Sell Custom Shirts Online Without Building a Website

You do not need a website to sell custom shirts online. Your Bear Grips Pro Shops storefront is a standalone page with its own URL. The link goes directly to your shop where members can browse products, select sizes, and pay. No website build required, no Shopify subscription, no Wix page to design.

1. Create a free vendor account at shops.beargrips.com/signup
2. Upload your business logo or design
3. Add the shirts you want to sell
4. Set retail prices
5. Copy your shop URL and share it

Your shop URL is shareable directly as a link in messages, emails, Instagram bio, or any communication channel you already use. No custom domain required to start.

How to Drive Your First Custom Shirt Sales Online

The most effective tactics for driving first sales from an existing fitness community:

• Direct message your most engaged members first: "Hey, we just launched our shop. Here's the link." A direct personal message from the gym owner or club director is the highest-converting outreach. Start with your 10 most engaged members before announcing broadly.
• Announce in class or at a group run: Face-to-face announcements convert better than email. Mention it at the end of class or during a group run cooldown when energy is high.
• Post a photo of the actual shirt: Share a photo of the shirt on a person or on a hanger with the club logo visible. Physical product photos convert far better than a plain shop link.
• Include in new member welcome: Add the shop link to your new member welcome message. New members are most enthusiastic and most likely to buy within the first 30 days.

Do not rely on organic social media posts alone for first sales. Direct communication with existing members is 10-20x more effective than hoping someone sees a post and clicks through.

Ongoing Strategy for Selling Custom Shirts Online

After the initial launch wave, custom shirt sales sustain through consistent but low-frequency promotion:

• Monthly mention in your newsletter or group chat: Include the shop link in your standard member communication once per month. Do not make it the focus, just include it as a resource.
• Seasonal collection announcements: When you add a sweatshirt in fall or a tank in summer, announce it. New product additions drive purchase spikes from existing members who are not in the market for a second shirt but are in the market for the first sweatshirt.
• New member wave targeting: January, September, and the beginning of sports seasons bring new member waves. Each new member cohort is a batch of first-time buyers.

The annual income from selling custom shirts online compounds as the community grows, not as the marketing budget grows. Consistent community building creates consistent shirt sales. See the make money selling shirts guide for full revenue math.

Expanding Beyond Shirts: Building a Full Online Merch Side Hustle

Shirts are the entry point. The full online apparel side hustle includes:

• Hats: The second most purchased item after shirts. Add a mesh snapback or rope hat to your shop after the first 30 days.
• Sweatshirts: Add a crewneck or hoodie in time for fall. Members who already have the shirt are now in the market for the layer.
• Tank tops or racerbacks: For warm-weather communities and women's fitness groups.
• Event-specific shirts: Annual competition, charity event, anniversary edition. Generates purchase motivation from members who already own the standard shirt.

Frequently Asked Questions

Can I sell custom shirts online without holding inventory?

Yes. Bear Grips Pro Shops uses print on demand: each shirt is printed after an order is placed and ships directly to the buyer. You hold no inventory at any time. Your upfront cost is zero. Revenue starts with the first order from your shop link.

How do I get people to buy from my custom shirt link?

Direct communication with your existing fitness community is the most effective approach. Send the link directly to your most engaged members first. Announce it in class or at a group event with a physical product photo. Include the link in your monthly member newsletter. New member welcome messages are the highest-converting single touchpoint.

Can I sell custom shirts on Instagram through Bear Grips Pro Shops?

Yes, indirectly. Bear Grips Pro Shops does not integrate directly with Instagram shopping, but you can place your shop link in your Instagram bio and link to it from Stories. When you post a photo of a member in your shirt and include the shop link in your bio, followers can click through to order. This is a standard link-in-bio merch approach used by coaches and gym owners.
