Consumers today don’t just want products, they want custom experiences. A report by Deloitte shows that over 50% of consumers express interest in personalized products, and 20% are even willing to pay a premium for them. The global custom product market is projected to hit $50 billion by 2028, fueled by rising demand for personalized apparel, packaging, signage, and gifts.

Whether you're in the game or just getting started with eCommerce, selling custom products online is a massive opportunity but only if you get the steps right. From selecting what to sell to building the right storefront and marketing it effectively, every part of the process needs to be optimized for personalization and performance.

7 Essential Steps for Selling Custom Products Online

Below are seven essential steps to help you build and grow a successful custom product business online.

Step 1: Choose the Right Custom Products to Sell

Your product catalog forms the backbone of your business. But instead of offering every customizable item imaginable, start with a lean, strategic approach.

Factors to Consider:

• Your niche: Weddings, eco-conscious buyers, corporate gifting, etc.
• Your capabilities: What you can print, fulfill, or source effectively
• Your target market: B2B, B2C, or both
• Profit margins: Include customization, materials, and fulfillment costs

Popular Custom Product Categories in 2025:

• Custom Apparel: T-shirts, hoodies, sportswear, baby wear
• Home Decor: Canvas prints, photo frames, custom wall decals
• Gifting Items: Mugs, calendars, puzzles, journals
• Event Products: Invitations, signage, party favors
• Corporate Merchandise: Branded pens, bags, lanyards, notebooks
• Custom Packaging: Boxes, labels, paper bags, tissue wraps
• Promotional Products: Stickers, buttons, keychains

Pro tip: Focus on niche products that hold emotional or functional value—like wedding signage, baby milestone cards, or sustainable packaging—which tend to convert better and allow for higher pricing. Custom products like wedding rings are also a strong example, as they combine emotional significance with personalization, making them an evergreen niche for sellers.

Step 2: Build a Storefront That Supports Customization

Custom product eCommerce is different from selling ready-made items. Your platform must support real-time personalization, file uploads, live previews, and pricing logic.

Must-Have Features for a Custom Product Store:

• Product personalization interface (text input, color, image uploads, templates)
• Live preview of the personalized product
• Dynamic pricing engine (based on design, size, or quantity)
• Product variants (material, size, finish)
• Real-time stock visibility and shipping estimation
• Customer dashboard for saving designs and reordering
• Automated order routing to print vendors or internal production

Tip: A web-to-print platform like DesignNBuy offers all of the above features along with scalable backends and B2B portals, making it easier to grow your custom business without technical complexity.

Step 3: Use a Powerful Product Personalization Software

The product design experience is a core part of your customer journey. A simple, mobile-friendly, and intuitive product personalization software will drive higher conversions and fewer support requests.

Key Features of a Modern Product Personalization Software:

• Drag-and-drop design editor with responsive layout
• Editable text fields with font, color, and alignment controls
• Image upload with cropping, resizing, and rotation tools
• Pre-loaded design templates, clipart, and design assets
• Real-time visual mockups of the final product
• Print-ready output generation (PDF, SVG, CMYK support)
• Multilingual and multi-currency compatibility for global selling

Best practice: Offer both template-based and form-based design modes to cater to different user types from casual shoppers to B2B professionals.

Step 4: Set Up Backend Processes for Fulfillment

Custom product fulfillment is more complex than standard orders. Each order is unique, requiring streamlined automation and clear tracking.

Fulfillment Workflow Components:

• Order intake and payment processing
• Design file verification and preflight checks
• Print job queue management
• Vendor routing or in-house production planning
• Inventory management (blank stock, materials, packaging)
• Shipping and return handling

Recommended Backend Tools:

• Order Management System (OMS)
• Print Workflow Automation Software
• Shipping integrations (FedEx, UPS, Delhivery, ShipStation)
• CRM for customer communication and support
• Production dashboard for real-time tracking

Tip: DesignNBuy's web-to-print ecosystem integrates these backend features seamlessly, reducing operational friction and ensuring timely delivery.

Step 5: Price for Profitability

Pricing custom products isn’t one-size-fits-all. You must balance product cost, customization complexity, and customer expectations while ensuring healthy margins.

Key Pricing Factors:

• Base product and material costs
• Customization charges (e.g., number of colors, print area, design time)
• Software and platform costs
• Packaging, labor, and fulfillment
• Customer acquisition cost (CAC)
• Taxes, transaction, and payment gateway fees

Pricing Best Practices:

• Use tiered pricing for larger quantities or simpler designs
• Implement dynamic calculators that adjust based on inputs
• Show unit savings for B2B or bulk orders
• Offer product bundles (e.g., mug + coaster, t-shirt + cap) to increase average order value

Step 6: Market Your Custom Store Strategically

A strong storefront needs equally strong marketing to attract customers. Use a mix of paid, organic, and referral channels to drive traffic and repeat business.

Top Channels to Promote Your Custom Store:

• Optimize category pages and product descriptions for high-intent search queries like “custom logo t-shirts” or “personalized packaging for small business.”
• Google Shopping & Meta Ads: Run product feed ads targeting location, audience segments, and events.
• Social Media Marketing: Use Instagram, Pinterest, and Facebook to highlight real customer designs, behind-the-scenes content, and seasonal promotions.
• Email Campaigns: Automate abandoned cart emails, order follow-ups, and seasonal offers.
• Influencer Partnerships: Collaborate with niche influencers (e.g., mom bloggers, wedding planners, small business coaches).
• B2B Outreach: Cold email campaigns to marketing agencies, HR teams, and event planners with a curated catalog or bulk discounts.

Content tip: Create helpful guides like “How to Design Custom Packaging for Your Brand” to drive traffic and establish authority.

Step 7: Enhance Customer Experience and Support

Customer experience defines your brand in the custom printing space. A seamless design process, clear timelines, and helpful support will increase customer trust and long-term loyalty.

Ways to Improve Customer Experience:

• Offer live chat or WhatsApp chat assistance during design
• Provide proof approval workflows before printing
• Enable design-saving for easy reordering
• Offer real-time order tracking and email/SMS notifications
• Package orders with care and include branding materials
• Collect and showcase customer reviews and photos for social proof

Loyalty tips: Provide small discounts on repeat orders or early access to new product launches. You can also offer design credits to encourage engagement.
