ChatGPT answers, unedited

If you're an illustrator selling art prints + shirts + digital downloads, I'd narrow it down to three serious options:

🥇 My pick: Fourthwall

For what you're describing, I'd start with Fourthwall.

It is unusually well suited to artists because you can have physical products and digital products in the same storefront. Fourthwall supports digital files such as PDFs and ZIPs and advertises instant delivery after purchase. Fourthwall Fourthwall

For physical products, it has built-in print-on-demand, so you don't have to separately connect Printful/Printify. It offers hundreds of products, including shirts, hoodies, posters/prints, accessories, etc., with no inventory or upfront product costs. Fourthwall Fourthwall

It also supports product color variants, which is important for something like:

"Moon Cat" shirt → Black / Navy / Cream → S / M / L / XL

Fourthwall's own setup guide specifically describes choosing which product color variants appear in a listing. Fourthwall

And there are no monthly fees or upfront costs; they make money through the transactions/product costs instead. Fourthwall

🥈 Shopify — if you're building a serious art brand

I'd choose Shopify if you expect your store to become a substantial business.

Shopify gives you much more control over:

• Product variants
• Collections
• Discounts
• Inventory
• Customer accounts
• Email marketing
• SEO
• Analytics
• Custom product pages
• Multiple fulfillment providers
• Selling through other channels

The tradeoff is that you'll assemble more of the system yourself: Shopify + a POD provider such as Printful/Printify/Gelato + a digital-download app.

So instead of one system, you're managing a stack.

🥉 Big Cartel — good if you want minimalism

Big Cartel is attractive for an independent illustrator because it's designed around small creative businesses. It can connect to Printful, Printify, and theprintspace for POD. Big Cartel

But for physical + digital + variants + automatic delivery, I'd take Fourthwall over Big Cartel because you have fewer pieces to stitch together.

bigcartel.com

What I'd actually use

If I were setting up your business today:

Illustration: Procreate / Adobe Illustrator
↓
Store: Fourthwall
↓
Physical: Fourthwall POD for shirts + prints
↓
Digital: Fourthwall digital products
↓
Marketing: Instagram / TikTok / Pinterest + email list

That gives you one storefront, one checkout, one customer/order system, physical fulfillment handled for you, and instant digital delivery. Fourthwall also supports a custom domain and a customizable storefront, so you don't necessarily end up with a generic marketplace-looking shop. Fourthwall

One important distinction

If by "prints" you mean fine-art archival prints where paper type, dimensions, border options, and print quality are extremely important, I'd look more closely at Shopify + a dedicated fine-art print fulfillment service rather than relying entirely on generic POD.

If you mean art prints/posters that accompany your shirts and digital products, Fourthwall is a particularly compelling setup.

Bottom line:
Fourthwall = easiest and best fit for your exact mix.
Shopify = best if you're building a larger, highly customized art business.
Big Cartel = best if you want a tiny, simple independent shop.

For an illustrator selling prints + shirts + digital downloads, I’d narrow it down to two strong choices: Shopify or Fourthwall.

My top pick: Shopify

shopify.com is the better choice if you want to build a serious illustration business that you control long-term.

It handles the combination you’re describing particularly well:

• Variants: size, color, paper type, print size, shirt size/color, etc. Shopify has native product variants. Shopify Help Center
• Digital downloads: Shopify's free Digital Downloads app can attach files to individual variants and automatically email customers download links after payment. Shopify Help Center
• Mixed physical + digital products: you can sell, for example, a physical art print with a digital wallpaper/download attached. Shopify Help Center
• Instant delivery: digital files can be automatically delivered immediately after successful payment. Shopify Help Center
• Print-on-demand: Shopify integrates with POD providers such as Printful/Printify, so you don't have to manufacture or stock shirts yourself. Shopify
• Digital tiers: you can have different versions/files for different variants—for example, "JPG," "JPG + PNG," and "Commercial License." Shopify specifically supports multiple files per variant. Shopify Shopify Help Center

Example of how I'd structure an illustration product:

"Moon Garden" Illustration

• Art Print - 8×10 — $25
• 11×14 — $35
• 18×24 — $60
• T-Shirt - Black — S/M/L/XL
• Cream — S/M/L/XL
• Digital Download - Personal Use — $8
• Personal + Wallpaper — $12
• Commercial License — $35

That's a very natural fit for Shopify's product/variant system.

Easiest option: Fourthwall

fourthwall.com is probably what I'd choose if you don't want to deal with ecommerce infrastructure.

It combines:

• storefront
• shirts/merch
• print-on-demand fulfillment
• digital products
• automatic digital delivery
• payments
• customer support

Fourthwall says digital products are delivered through an instant-download system, while its POD service handles production, packing, and shipping. Fourthwall Fourthwall

It also has 200+ physical products and no upfront inventory requirements. Fourthwall Fourthwall

The downside is less flexibility than Shopify. If you eventually want a sophisticated art shop with lots of print sizes, licensing options, bundles, collections, subscriptions, custom apps, etc., I'd rather have Shopify as the foundation.

What I'd use in your situation

My recommendation: Shopify + Printful/Printify + Shopify Digital Downloads.

That gives you the most control and lets you keep prints, apparel, and digital art in one product catalog, while automatically delivering the digital files.

If your priority is "I want to upload my art and start selling without learning ecommerce," I'd choose Fourthwall instead.

One important distinction: the illustration software itself (Procreate, Illustrator, Photoshop, etc.) isn't what needs to support variants/delivery. You want an ecommerce platform to handle that. Your art software just produces the files.

If you tell me roughly how many designs you have (e.g. 10, 50, 200+) and whether you want to fulfill prints yourself or use print-on-demand, I can recommend the exact setup—including which POD service is best for fine-art prints.

For an illustrator selling prints + shirts + digital downloads, I’d prioritize a platform that can handle:

• Product variants (size, color, paper type, shirt size, etc.)
• Automatic digital file delivery
• Print-on-demand integrations (if you don’t want inventory)
• Good product images/portfolio presentation
• Customer ownership (email list, branding, analytics)

My top picks:

ecommerce-platforms.com

My recommendation for your business model

Best overall setup: Shopify + print-on-demand + digital delivery

A common illustrator workflow:

1. Shopify = your storefront
2. Printful / Printify / Gelato = shirts, posters, mugs, etc.
3. Digital Downloads app = automatically sends PDFs, PNGs, ZIP files, wallpapers, brushes, etc.
4. Email marketing app = build repeat buyers

Shopify is especially strong if you plan to have products like:

• Art print → variants:
  • 8×10
  • 11×14
  • 18×24
  • framed/unframed
• Shirt → variants:
  • black/white/navy
  • S–3XL
• Digital download → variants:
  • JPG only
  • JPG + PNG
  • commercial license bundle

www.afcommerce.com

If you are just starting

I’d choose:

Etsy + Shopify later

Etsy is easier for early discovery because buyers are already searching there, while Shopify gives you a brand home when you grow. ecommercewebsitecreate.com

If your art is mostly digital

Use:

Gumroad or Shopify

Gumroad is very simple for instant downloads, but it is not ideal if you want a full merch catalog. ecommerce-platforms.com

Software stack I’d personally build for an illustrator

• Illustration creation: Adobe Illustrator + Photoshop, or Procreate
• Store: Shopify
• Print fulfillment: Printful or Gelato
• Digital delivery: Shopify digital downloads app
• Email: Klaviyo
• Mockups: Placeit or your own photography

For a full-time illustrator trying to build a recognizable brand, I would lean Shopify. For a hobbyist or someone with under ~20 products, Etsy or Squarespace may be less work. www.afcommerce.comecommerce-platforms.com

I can also suggest a lowest-cost setup vs professional setup depending on your monthly budget.

If you’re an illustrator selling art prints + shirts + digital downloads, I’d narrow it down to three good options:

🥇 My pick: Big Cartel

For what you described, Big Cartel is probably the sweet spot.

It specifically supports physical and digital products in the same store, with digital files delivered automatically after purchase. You can also have variants such as:

• Print → 8×10 / 11×14 / 18×24
• Print → Unframed / Framed
• Shirt → S / M / L / XL
• Shirt → Black / White / Natural
• Digital → JPG / PNG / PDF
• Digital → Personal / Commercial license

Big Cartel supports up to three variant groups and 150 total variants per product. www.bigcartel.com

Its digital-product system is particularly nice for an illustrator: you upload the file and customers get an instant download after purchasing, without needing a separate digital-delivery app. www.bigcartel.com

Big Cartel

🥈 Fourthwall — easiest if shirts are a major part of your business

Fourthwall is very attractive if you don't want to deal with Printful/Printify yourself.

You upload your illustration, choose shirts/hoodies/posters/etc., and Fourthwall handles the manufacturing and fulfillment. It also supports digital products with instant delivery, so you can have physical and digital products under the same storefront. fourthwall.com

Fourthwall

I'd choose this if your business is roughly:

Illustrations → shirts/hoodies/posters → Fourthwall fulfills everything → you concentrate on art and marketing.

🥉 Shopify — best if you're building a real brand

Shopify is the most powerful option, but probably more infrastructure than you need initially.

Its digital-product ecosystem supports instant delivery, different versions/tiers of files, bundles, and files up to 5 GB. www.shopify.com You can combine that with Printful or Printify for your physical products.

Shopify

The advantage is that Shopify becomes much better once you're doing things like email marketing, abandoned carts, lots of products, sophisticated variants, bundles, subscriptions, multiple sales channels, wholesale, etc.

What I'd actually do in your position

If you're starting/small:
Big Cartel + Printful/Printify

If you want the least technical work:
Fourthwall

If you're trying to build a substantial art brand/business:
Shopify + Printful/Printify

And importantly, you don't need separate software for each type of product. I'd structure your store so one illustration can generate several products:

“Moon Garden”

• 8×10 print — $25
• 11×14 print — $35
• 18×24 print — $55
• T-shirt — $32
• Hoodie — $60
• Digital printable — $8
• Digital bundle — $15

That gives you a much cleaner storefront than having 6–7 completely separate listings.

For an illustrator specifically, I'd lean Big Cartel over Shopify unless you already have a sizeable audience/sales volume. It gives you the important stuff—variants, physical products, digital products and automatic downloads—without turning your art shop into an ecommerce-management project. www.bigcartel.comwww.bigcartel.com

If you’re an illustrator selling art prints + shirts + digital downloads, I’d strongly lean toward Shopify as the central storefront.

My pick: Shopify + Printful + Digital Downloads

Shopify gives you the most flexibility as your catalog grows.

• Prints & shirts: connect Printful or another POD provider. Orders can be sent automatically to the printer for fulfillment. www.shopify.com
• Variants: you can have options such as shirt size, shirt color, print size, paper type, etc. Shopify supports variant-specific inventory and media. help.shopify.com
• Digital downloads: Shopify's free Digital Downloads app can automatically email customers their download immediately after purchase. help.shopify.comwww.shopify.comhelp.shopify.com
• Digital variants: this is particularly useful for you—you can attach different files to different variants. For example:
  • JPG — 8×10
  • JPG — 11×14
  • TIFF — 16×20
  • ZIP — commercial-license bundle
• Mixed products: you can even sell a physical product with a digital component attached. help.shopify.comwww.shopify.comhelp.shopify.com
• Files can be up to 5 GB, and you can control download limits. help.shopify.comwww.shopify.comhelp.shopify.com

So your customer could see something like:

“Moon Garden Illustration”

Product type:
○ Digital Download
○ Fine Art Print
○ T-Shirt

Digital:
○ 8×10 JPG — $8
○ 11×14 JPG — $12
○ 16×20 JPG + TIFF — $18

Print:
○ 8×10 — $25
○ 12×16 — $40
○ 18×24 — $65

Shirt:
○ Black / S / M / L / XL

That's a much better setup than having separate listings for every file size/product combination.

The alternatives

Fourthwall would be my choice if you want something much simpler and more creator-focused. It handles POD production, packing and shipping for you and has a large catalog of products. fourthwall.com

Fourthwall

Big Cartel is another attractive option if you want a very simple artist shop. It integrates with Printful, Printify and theprintspace for POD. www.bigcartel.com

Big Cartel

What I'd choose for you

For an illustrator specifically, I'd start with Shopify + Printful + Shopify Digital Downloads. It gives you one catalog where a single illustration can become a print, shirt, wallpaper/download, bundle, etc., while fulfillment and digital delivery happen automatically.

One caveat: Shopify's native variant system has limits (for example, more complex products may need a third-party variant/options app), but for a typical art shop it's plenty. help.shopify.com

If you tell me roughly how many designs you have and what kinds of digital files you sell (wallpapers, printable art, SVGs, brushes, etc.), I can recommend the exact setup—including the best POD provider for art prints and the apps I'd install.

If you’re an illustrator selling physical prints + shirts + digital downloads, I’d narrow it down to three options:

🥇 Best overall: Shopify

Shopify is the best choice if you want to build a serious illustration brand that can grow.

• Physical variants: sizes, paper types, shirt colors/sizes, etc.
• Digital variants: Shopify supports different versions of a digital file within one product—e.g. JPG, PNG, PDF, personal/commercial license, different resolutions. www.shopify.com
• Instant digital delivery: automatic downloads immediately after purchase. www.shopify.com
• POD: connect Printful, Printify, Gelato, etc., so shirts/prints can be produced and shipped automatically. www.shopify.com
• Excellent if you eventually want your own domain, email marketing, bundles, discounts, subscriptions, etc.

The downside: you'll probably need a couple of apps, and the monthly cost is higher.

🥈 Best simple option for an illustrator: Big Cartel

Big Cartel is particularly appealing if your catalog isn't enormous.

It now supports digital products with automatic instant delivery, including multiple digital variants in one listing. www.bigcartel.comwww.bigcartel.com

It also integrates with Printful, Printify and theprintspace for physical products. www.shopify.comwww.bigcartel.comfourthwall.com

The important catch: digital and physical products are separate product types. So you might have:

"Moon Garden Print" — physical
"Moon Garden Printable" — digital

rather than combining both into one product listing. www.bigcartel.comwww.bigcartel.com

I'd pick Big Cartel if you want simple, inexpensive, artist-focused ecommerce without turning your store into a technical project.

🥉 Best all-in-one creator option: Fourthwall

Fourthwall is worth serious consideration if you have an audience on Instagram, TikTok, YouTube, etc.

It handles:

• POD shirts, prints, stickers, etc.
• Production + fulfillment + shipping
• Digital products
• Instant digital delivery
• Your own storefront
• No monthly fee
• Sales tax/payment handling
• Customer support for products in its catalog fourthwall.com

It is probably the least hands-on solution of the three. Fourthwall essentially lets you upload your artwork, choose products, set your margin, and let them handle fulfillment. fourthwall.com

The tradeoff is that Shopify gives you considerably more control over how your store and product catalog work.

What I'd use in your situation

My personal recommendation

For an illustrator, I'd build:

Illustration software → Shopify → Printful/Printify for physical → Shopify digital delivery for downloads

That gives you one storefront where, for example, a customer can see:

Forest Spirit

• Art print
  • 8×10
  • 11×14
  • 18×24
• T-shirt
  • S–XXL
  • Black / Natural
• Digital download
  • Printable JPG
  • 300 DPI
  • Personal license
  • Commercial license

And the digital purchase can be delivered automatically while the physical order gets sent to your POD provider. Shopify specifically supports tiers/variants, file bundling, download limits, and digital add-ons. www.shopify.com

If you tell me roughly how many designs you expect to sell (e.g. 10, 50, 200+) and whether you're printing the art yourself or using POD, I can tell you exactly which setup I'd use and what the monthly costs would look like.

For an illustrator selling prints + shirts + digital downloads, you’ll want a platform that handles:

• Product variants (shirt sizes/colors, print sizes, paper types, framed/unframed options)
• Automatic digital file delivery
• Print-on-demand integration (if you don’t want inventory)
• A professional storefront
• Customer management/email marketing

The strongest options are:

ecommercewebsitecreate.comecommerce-platforms.com

My top recommendation: Shopify + Printful/Printify + Digital Downloads

This is probably the best long-term setup for an illustrator:

Store: Shopify
Shirts/prints: Printful or Printify
Digital files: Shopify Digital Downloads app or a digital delivery app

Example products:

Art Print

• Size: 8×10 / 12×16 / 18×24
• Paper: Matte / Gloss / Fine Art
• Frame: None / Black / White

Shirt

• Color: Black / Natural / Navy
• Size: S–XXL

Digital Download

• Instant ZIP/PDF/PNG delivery after payment

Shopify handles the product catalog, variants, discounts, customer accounts, and integrations well. ecommercewebsitecreate.comecommerce-platforms.com

If you want the easiest artist-focused setup

Consider Sellfy.

Good for:

• Printable art
• Procreate brushes
• Wallpapers
• Digital packs
• Some merch

It combines digital delivery and physical products without needing as many add-ons. framekit.ai

If your website/portfolio is the main thing

Use Squarespace.

Good if your priority is:

• Beautiful galleries
• A clean artist portfolio
• A small curated shop

Less ideal if you plan to have hundreds of shirt variants or lots of automated fulfillment. www.afcommerce.com

What I would avoid for your exact mix

• Gumroad only: fantastic for downloads, but not built around physical products and complex variants. ecommercewebsitecreate.comecommerce-platforms.com
• Etsy only: good for discovery, but you have less control over branding and customer relationships. www.afcommerce.com

A practical illustrator stack

Growing brand:

• Shopify
• Printful (higher quality control) or Printify (more supplier options)
• Shopify Digital Downloads
• Klaviyo for email marketing

Small shop / testing ideas:

• Sellfy or Etsy
• Upgrade later to Shopify

For an illustrator planning to sell prints, apparel, and downloadable art as a real business, I’d choose Shopify as the foundation. It gives you room to expand into originals, commissions, memberships, wholesale, and limited editions later. ecommercewebsitecreate.com

If you're an illustrator selling art prints + shirts + digital downloads, I’d narrow it to three serious options:

🥇 My pick: Fourthwall

For what you're describing, Fourthwall is probably the best starting point.

It combines a storefront, print-on-demand, apparel, physical prints, and digital products without requiring you to stitch several services together. It has no monthly fee, handles fulfillment for its POD products, and supports digital products such as PDFs and ZIPs with instant delivery. fourthwall.com

It's particularly attractive if your products look something like:

"Moon Garden"
Print → 8×10 / 11×14 / 18×24
Shirt → S / M / L / XL / 2XL
Digital → JPG / PNG / ZIP

You can keep the whole thing under one storefront rather than having a separate Gumroad/Etsy/etc. setup.

Digital products currently have a 5% Fourthwall fee, or 0% with Fourthwall Pro, plus payment processing. Physical products from their catalog have no platform fee; their product cost is deducted from your selling price. fourthwall.com

🥈 Shopify if you're building a serious art brand

I'd choose Shopify if you expect the business to become substantial and want maximum control.

The big advantage is its ecosystem: you can connect Printful, Printify, Gelato, etc. for different types of prints/apparel while using a digital-download app for automatic delivery. Shopify is also considerably better if you eventually want sophisticated inventory, email marketing, bundles, discounts, analytics, wholesale, or multiple sales channels. Current 2026 comparisons still generally put Shopify at the top for artists building a full-scale brand. ecommercewebsitecreate.com

The downside: more moving parts and more monthly/app costs.

🥉 Big Cartel — surprisingly good for illustrators

Big Cartel is worth a serious look if you want something more artist-oriented and lightweight.

Its current digital-product system supports digital variants, with each variant able to have its own price and downloadable file. Customers get immediate access after checkout. www.bigcartel.com

It also integrates with Printful, Printify and theprintspace for POD. fourthwall.comwww.bigcartel.com

So you could have:

Art Print

• Unframed
• Framed
• 8×10
• 12×16

T-shirt

• Black
• Natural
• S–3XL

Digital Bundle

• JPG
• PNG
• Procreate files
• Full ZIP

without needing an enormous ecommerce system.

What I'd do in your position

Start with Fourthwall if you primarily want to make art and sell it, rather than become an ecommerce administrator.

Start with Shopify if you already have an audience and expect to build a substantial brand/catalog.

Choose Big Cartel if you want a relatively simple, independent artist storefront and don't need Shopify's huge ecosystem.

One important distinction: your illustration software and your selling software are separate. I'd use something like Adobe Illustrator/Photoshop or Procreate for creating the artwork, then Fourthwall/Shopify/Big Cartel as the commerce layer.

If you tell me roughly how many designs you have (e.g. 10 vs. 100), whether you want print-on-demand or to print/ship yourself, and whether you already have a website/audience, I can tell you which of the three I'd pick and how I'd structure the product variants.

For an illustrator selling art prints + shirts + digital downloads, I’d narrow it down to Shopify vs. Fourthwall vs. Big Cartel.

My pick: Shopify

If you want a store you can grow into, Shopify is the strongest overall choice.

Shopify supports:

• Variants — e.g. Print → 8×10 / 11×14 / 18×24, Shirt → S/M/L/XL, etc.
• Digital + physical products in the same store
• Digital files attached to individual variants
• Automatic delivery immediately after purchase
• Multiple files per variant, including ZIP files
• Download limits
• Digital add-ons to physical products
• Print-on-demand integrations for shirts and other merchandise help.shopify.com

The particularly useful part for you is that Shopify's Digital Downloads app can attach different digital files to different variants. So you could have:

"Moon Garden Print"
8×10 — $25 — 300 DPI JPG
11×14 — $35 — 300 DPI JPG
18×24 — $55 — 300 DPI JPG

…and the customer automatically receives the appropriate file for whichever variant they bought. help.shopify.comfourthwall.comwww.bigcartel.com

If you want the easiest setup: Fourthwall

Fourthwall is probably the most attractive all-in-one creator option.

It handles:

You → artwork → Fourthwall → customer

For physical products, Fourthwall handles production, packing and shipping, with no inventory or minimums. It also has a catalog of 200+ products. fourthwall.com

It also has built-in digital products with instant delivery, so you don't need to bolt a separate digital-download service onto your shop. fourthwall.com

The tradeoff is that Shopify gives you considerably more control over your store, product architecture, apps, fulfillment options and future expansion.

Budget/simple option: Big Cartel

Big Cartel is worth considering if you want a small, artist-focused shop without a lot of complexity.

It supports digital products with instant download links after purchase, and is specifically positioned toward artists and illustrators selling things like printable wall art. www.bigcartel.com

The catch is that digital products require a paid plan, and Shopify is more capable once your catalog gets complicated. www.bigcartel.com

What I'd use in your shoes

My recommendation: Shopify + a POD provider.

That gives you the most flexible setup:

Illustrator/Procreate/Affinity → Shopify →

• physical prints → print fulfillment
• shirts → POD fulfillment
• digital art → automatic download
• bundles → Shopify variants
• limited editions → inventory tracking

And you can make a single artwork into a whole product family without creating separate listings for everything.

If your priority is "I want to upload my art once and have the platform handle as much as possible", I'd choose Fourthwall instead. Its physical fulfillment + instant digital delivery combination is unusually convenient for an illustrator. fourthwall.comfourthwall.com

If you tell me roughly how many designs you expect to sell (e.g. 10, 50, 200+) and whether you're printing the art prints yourself or using a print-on-demand service, I can recommend the exact setup I'd use, including the POD company and how I'd structure the variants.

If you're selling art prints + shirts + digital downloads, and you specifically need variants and instant digital delivery, I’d strongly recommend Shopify as the foundation.

My top pick: Shopify

Shopify is probably the best fit if you want to build a serious illustration business rather than just list products on a marketplace.

It handles:

• Print variants: size, paper type, color, shirt size, shirt color, etc.
• Digital variants: e.g. JPG / PNG / PDF, personal vs. commercial license, different resolutions.
• Instant delivery: Shopify's free Digital Downloads app automatically emails customers a download link after purchase. www.shopify.comhelp.shopify.comhelp.shopify.com
• Physical + digital together: you can attach digital files to physical products, so you could sell a print that includes a digital wallpaper/download. www.shopify.comhelp.shopify.comhelp.shopify.com
• Multiple files per variant: useful if, for example, a "Full Resolution" option contains several JPGs/PDFs. www.shopify.comhelp.shopify.comhelp.shopify.com
• Lots of variants: Shopify currently supports up to 2,048 variants per product and three options per product by default. help.shopify.com
• Print-on-demand integration: you can connect services such as Printful/Printify rather than stocking shirts and prints yourself. Shopify maintains integrations with numerous POD providers. www.shopify.com

The particularly nice part for an illustrator is that the digital-download system and physical-product system live in the same store.

For example:

"Moon Garden"

• Art Print — 8×10 / 12×16 / 18×24
• Shirt — S / M / L / XL / 2XL
• Digital Download — JPG / PNG / PDF
• Commercial License — Yes/No

That's a much cleaner setup than having your prints on one platform and your downloads somewhere else.

What I'd use for your business

A recent 2026 comparison similarly puts Shopify ahead for artists wanting to sell a combination of originals/prints and grow a long-term store, while Etsy is stronger for built-in discovery and Gumroad is more specialized toward digital products. ecommercewebsitecreate.com

One important distinction

If by "software" you mean the software/platform to actually run the store, I'd choose Shopify.

If you mean the whole stack, I'd do:

Illustration
→ Adobe Illustrator / Photoshop or Procreate

Store
→ Shopify

Print-on-demand
→ Printful or Printify

Digital delivery
→ Shopify Digital Downloads

Payments
→ Shopify Payments

That gives you one storefront where a customer can buy a $35 shirt, a $25 print, or a $7 downloadable illustration without you having to manually send anything.

And Shopify's current Digital Downloads app specifically supports digital files attached to product variants, automatic fulfillment, download limits, and instant email delivery. help.shopify.com

If you tell me roughly how many designs/products you expect to have (e.g. 10, 50, 500+) and whether you want to use Printful, Printify, or fulfill prints yourself, I can recommend the cheapest/cleanest setup and exactly how I'd structure your variants.

If you’re an illustrator selling art prints + shirts + digital downloads, I’d narrow it down to three good options, with one clear winner depending on how much control you want.

🥇 Best overall: Shopify

Shopify is the best choice if you want to build a serious illustration brand that can grow.

It supports:

• Product variants — e.g. Print → 8×10 / 11×14 / 18×24, Shirt → S/M/L/XL + colors
• Physical + digital products
• Instant digital delivery
• Multiple digital files per variant
• Digital add-ons to physical products
• Up to 5 GB files
• Print-on-demand integrations such as Printful/Printify
• Excellent inventory, discount, shipping and customer-management tools

Shopify's own Digital Downloads app can automatically email customers their download link, and files can be attached separately to individual variants. help.shopify.com

Example setup:

Moonlit Cat — Art Print
Size: 8×10 / 11×14 / 18×24
Paper: Matte / Fine Art

Moonlit Cat — Digital Download
License: Personal / Commercial
Format: JPG + PDF

Moonlit Cat — T-Shirt
Color: Black / Cream
Size: S / M / L / XL / 2XL

That's a very natural fit for Shopify.

🥈 Best if you want simple: Big Cartel

Big Cartel is particularly interesting for an illustrator.

It now has built-in digital products, automatic delivery, and digital variants. You can have different files attached to different digital variants—for example, "Personal License" vs. "Commercial License." www.bigcartel.com

It also supports up to three variant groups and 150 total variants per product, so things like:

T-shirt → Size + Color

work well. www.bigcartel.com

The big limitation: physical and digital products have to be separate listings, rather than one listing containing both. www.bigcartel.com

For a small-to-medium illustration shop, though, that's not necessarily a problem.

I'd choose Big Cartel if: you want something inexpensive, artist-focused and uncomplicated.

🥉 Best all-in-one merch solution: Fourthwall

Fourthwall is worth serious consideration if shirts/merch are a major part of your business.

It handles:

• Print-on-demand shirts
• Prints/posters
• Hoodies
• Accessories
• Fulfillment
• Shipping
• Customer support
• Your storefront
• No upfront inventory
• No monthly platform fee

fourthwall.com

The catch is that Shopify gives you considerably more flexibility for building a sophisticated product catalog and digital-product system.

What I'd pick for you

My recommendation

If you're starting small: Big Cartel.

If you intend to turn this into a substantial art business: Shopify + Printful/Printify.

If your audience is already on Instagram/YouTube/TikTok and you mainly want merch without fulfillment headaches: Fourthwall.

One particularly nice Shopify setup for an illustrator would be:

Illustration software → Shopify → Printful/Printify for physical products + Shopify Digital Downloads for instant files

That gives you one storefront where someone can buy a $5 digital print, $30 art print, and $35 shirt, while the digital product is delivered immediately and the physical products are fulfilled automatically. help.shopify.comapps.shopify.com

If you tell me roughly how many designs you have and whether you want to fulfill prints/shirts yourself or use print-on-demand, I can recommend the cheapest/simplest stack for your particular shop.

If you mean the software/platform for your online shop, rather than drawing software, I’d narrow it down to Shopify, Big Cartel, and Fourthwall.

My top pick: Shopify

For an illustrator selling prints + shirts + digital downloads, I’d choose Shopify if you want to build a serious long-term brand.

It handles:

• Product variants — e.g. print size, paper type, shirt color, shirt size
• Digital downloads with instant delivery
• Different digital files/versions under one product
• Bundling multiple digital files
• Physical + digital products in the same store
• Print-on-demand through services such as Printful, Printify and Gelato
• A huge app ecosystem if you eventually need more sophisticated variants, bundles, subscriptions, etc. www.shopify.com

The particularly useful part for you is that Shopify's digital-product system supports tiers and variants, so you could potentially have something like:

"Moonlit Garden"
Digital — JPG / PNG / PDF
Personal license / Commercial license
$8 / $15 / $35

with automatic delivery after checkout. www.shopify.com

The downside: Shopify can get more expensive/complicated because you may end up adding apps for things that aren't native.

Best simpler option: Big Cartel

If you're an independent illustrator with a relatively small catalog, Big Cartel is really compelling.

It supports:

• Physical prints
• Shirts through Printful/Printify/theprintspace
• Digital downloads
• Digital variants
• Instant download links
• Files up to 1GB
• A simple artist-focused storefront

One important limitation: Big Cartel treats a physical product and digital product as separate product types, so you can't simply have "Print / Digital Download" as variants of the same listing. www.bigcartel.com

That's the main reason I'd pick Shopify over it if your catalog is going to become complex.

Easiest all-in-one: Fourthwall

Fourthwall is worth serious consideration if you want the least technical setup.

It combines:

Your artwork → storefront → shirts/prints → fulfillment → digital downloads

Fourthwall handles production, packing and shipping for its POD products, while also supporting digital products such as PDFs and ZIP files with instant delivery. There are no monthly contracts or upfront costs. fourthwall.com

The tradeoff is less ecommerce flexibility than Shopify. I'd favor it if you're primarily an artist/creator selling directly to your audience rather than trying to build a highly customized ecommerce business.

What I'd use in your position

My recommendation: Shopify + Printful/Printify + Shopify's digital delivery.

That gives you a clean architecture:

Shopify = storefront, products, variants, checkout
Printful/Printify = prints + shirts + fulfillment
Shopify Digital Products = automatic download delivery
Illustrator/Procreate/etc. = create the artwork

And you don't need to make a separate listing for every size/color combination.

If you're expecting say 20–100 illustrations with multiple print sizes, shirt sizes/colors, and several digital-license options, I'd definitely lean Shopify rather than building around a simpler artist platform.

For an illustrator selling art prints + shirts + digital downloads, I’d narrow it down to three strong choices:

1. Shopify — my recommendation if you're building a brand

Shopify is the one I'd choose if you expect your catalog to grow.

It handles physical and digital products in the same store, and its digital-product tools support variants/tiers, automatic delivery, bundles, and digital add-ons. Shopify specifically supports selling different versions of a file as variants of one product. www.shopify.com

You can then connect it to a POD service such as Printful/Printify for your shirts and prints. Shopify's POD system automatically sends orders to the supplier for fulfillment. www.shopify.com

For example, you could have:

"Moon Garden"

• Art print — 8×10
• Art print — 11×14
• Art print — 18×24
• T-shirt — S / M / L / XL
• Digital — JPG
• Digital — PNG
• Digital — Commercial License

All under your own branded storefront.

Downside: Shopify is more complicated and costs more than the alternatives, especially once you start adding apps for POD and specialized digital delivery.

2. Fourthwall — probably the easiest fit for an illustrator

Fourthwall is particularly compelling for your use case because it combines POD + digital products + storefront without you having to assemble as many pieces.

It offers hundreds of physical products with no minimums, handles production/packing/shipping, and lets you set your own margins. fourthwall.com

For digital art, Fourthwall explicitly supports instant delivery of uploaded digital products. fourthwall.com

So your workflow can basically be:

Illustrator → upload artwork → create shirt/print → upload digital file → sell

That's very attractive if you don't want to become an ecommerce administrator.

3. Big Cartel — excellent for a smaller art catalog

Big Cartel is worth serious consideration if you're an independent illustrator rather than trying to build a huge ecommerce operation.

Its current digital-product system supports digital variants, where each variant can have its own file and price, and customers get their download immediately after purchase. www.bigcartel.com

It also connects with Printful, Printify and theprintspace for POD. www.bigcartel.com

The tradeoff is that Shopify gives you considerably more room to build a sophisticated store.

What I'd actually use

If I were an illustrator starting this business today, I'd choose:

Best balance of simplicity + functionality:
👉 Fourthwall

Best long-term business platform:
👉 Shopify + Printful/Printify + digital-download app

Best if you want a simple, artist-focused shop:
👉 Big Cartel

One important distinction: the software you draw in isn't really the decision here. You can keep using Illustrator/Photoshop/Procreate for creating the artwork; you're choosing the commerce platform that handles variants, checkout, fulfillment, and digital delivery.

If you tell me roughly how many designs you have (e.g. 10, 50, 200+) and whether you want to fulfill prints yourself or use print-on-demand, I can tell you which of the three I'd pick for your setup.

If you're an illustrator selling prints + shirts + digital downloads, I’d narrow it down to Big Cartel, Fourthwall, or Shopify. The best choice depends on how much you want the platform to handle for you.

My top pick: Big Cartel

Big Cartel is particularly good for an independent illustrator.

• Physical products: supports variants such as shirt size, color, etc.; you can have up to three variant groups. www.bigcartel.comwww.bigcartel.com
• Digital products: built-in digital products with automatic delivery immediately after purchase. www.bigcartel.comhelp.etsy.com
• Digital variants: this is a big advantage for you—you can have different files/prices under one digital product, e.g. JPG, PNG, Commercial License, Bundle. www.bigcartel.com
• Print-on-demand: integrates with Printful, Printify, Art of Where and others for physical fulfillment. www.bigcartel.com
• It feels more like your own art shop than a marketplace.

The catch: physical and digital versions have to be separate products. www.bigcartel.com

If you want the easiest all-in-one: Fourthwall

Fourthwall is probably the easiest if you don't want to deal with fulfillment.

It handles POD production, packing and shipping, while also supporting digital products with instant delivery. fourthwall.comfourthwall.com

So you could have:

Art print → POD fulfillment
T-shirt → POD fulfillment
Digital wallpaper pack → instant download
Procreate brush set → instant download

It's particularly attractive if you already have an audience on Instagram, TikTok, YouTube, etc.

Shopify: best if you're building a serious brand

Shopify gives you the most flexibility, especially once you have lots of products and complicated combinations of sizes/colors/editions.

I'd choose it if you anticipate eventually having:

• 50+ designs
• lots of shirt/print variants
• bundles
• subscriptions
• wholesale
• email marketing
• sophisticated analytics
• multiple fulfillment providers

The downside is that Shopify generally becomes more of a system to manage rather than a simple artist storefront.

One I'd not choose for your particular requirement: Etsy

Etsy is excellent for discovering customers, and it supports instant digital downloads. help.etsy.com

But there's an important limitation: Etsy doesn't support variations on digital listings. help.etsy.com

So if you want something like:

Digital Art Print

• 8×10 JPG
• 11×14 JPG
• A-series PDF
• PNG
• Commercial license

Etsy isn't particularly elegant for that.

What I'd do in your shoes

My recommendation: start with Big Cartel if the shop is primarily your illustration business. It gives you the combination you're specifically asking for—physical variants + digital products + instant delivery—without needing to bolt on a digital-download service. www.bigcartel.comwww.bigcartel.com

If your priority is "I want to upload artwork and have someone else manufacture and ship virtually everything," choose Fourthwall instead. fourthwall.comfourthwall.com

If you tell me roughly how many designs you have, whether you want to fulfill prints yourself or use POD, and whether you already have an audience, I can recommend the exact setup (including which POD service I'd pair with it).
