Straight answers, no fluff.

Yes, and it stays accurate. Upload a layered PSD and Customei rebuilds it as a template: the layer tree and names carry over, every layer lands at its exact pixel coordinates at the document's native size, and text layers stay editable with their font, size, tracking and leading. Missing fonts are reported rather than silently substituted, so you can upload the licensed file and re-import.

Yes, from Basic to Plus. On non-Plus stores we use hidden fee variants to add personalization pricing; on Plus we switch to a Cart Transform Shopify Function. The transition is automatic the day you upgrade.

Every plan (Maker, Studio, Atelier) ships with a 14-day trial. No credit card required. You can cancel from the Shopify admin in a single click, and nothing is charged until day fifteen.

They are dedicated layer renderers. Star maps draw the exact night sky for any date and lat/long via d3-celestial. String art turns a customer-uploaded photo into thread paths on a circular board. Crosswords run as a Lambda service that renders print-ready 3000x3000 puzzles from a word list, with four theme and grid presets. Interactive Mapbox maps, word clouds and word searches round out the set.

Yes. Customei supports customer uploads with automatic moderation and an optional manual review queue. Files are stored on Cloudflare R2 with signed URLs your fulfilment partner can read.

Our print pipeline runs on Lambda workers that render layered files at 300dpi, preserving the original color spaces and fonts. We deliver ready-to-print files to your fulfilment partner via S3, direct API, signed URL or webhook, and delivery state is recorded per file.

In Cloudflare R2, reached through signed URLs. Full-resolution originals go in a separate private bucket, and the backend refuses to boot without one, so an original is never served from a public bucket. The design record is stored apart from the rendered print file, so a file can be re-rendered or removed on its own.

On top of the base subscription you pay a small fee for each personalized item you sell. Quantity does not multiply it: three of the same engraved mug on one order line is one item, while three mugs each personalized differently is three. The fee is tiered by volume — once you pass a threshold inside a billing cycle, every further item is charged at the lower rate, automatically.

Plans are chosen mainly on what you can build (templates, uploads and integrations), not on the per-item fee.

Each personalized order line counts once, however many units it carries. A design that prints more than one sheet counts once per sheet, since each sheet is a separate print file.

An item is only counted once its artwork has rendered, so a render that fails costs you nothing. Regular, non-personalized products in the same order are never charged.

If you sell straightforward variations of a product, such as sizes or engraving text, and one artwork layout covers it, Maker is enough: option sets are unlimited there and you get one design template.

Move to Studio the moment an option needs to change the price, or you need a catalogue of different artwork, product mockups, your own fonts or a second store. Atelier is for production output (every print format, CMYK, 600 DPI) and outside integrations.

Yes, on the usage side. Each subscription carries a capped amount for personalization fees, derived from your plan's own rate ladder and never set below $8,000 per cycle. Shopify refuses any usage charge past that cap, so a sudden spike in orders cannot produce a surprise bill.

The base subscription is separate and always the plan price you signed up on.

Every plan starts with a free trial, so there are no charges while it runs. When the trial ends, the base subscription begins automatically on your Shopify invoice.

Cancel any time during the trial and you won't be charged.

Yes. Upgrade or downgrade any time from the billing page in the app. Shopify handles proration automatically on your next bill.

All charges go through Shopify Billing and show up on your regular Shopify invoice, with no separate payment method needed.

No. Customei has no preferred supplier and takes no cut of production. If your partner can read a file from a bucket, an API call, a signed link or a webhook, they are supported today.

A print-ready file at 300dpi with bleed, safe area and any cut path already applied, named with the order number, line item and panel — plus the option values, so they can verify without opening the design.

Yes. Proofing can be set to auto-approve, to require review on specific conditions (an upload, a long inscription, a high-value order), or to require review on everything.

Re-render it from the order. The design record is stored separately from the rendered file, so fixing a font or a print area and re-rendering does not require the customer to reorder.

On Cloudflare R2, reached through signed URLs. Full-resolution originals live in a separate private bucket, which the backend requires at boot — so an original is never served from a public one.

No. A flat mockup needs no mesh at all — leave the handles at the corners and it behaves like a normal rectangle. You only reach for the mesh on curved surfaces: drinkware, phone cases, caps, cushions, anything with a seam.

The mesh is a shader transform, not an image round-trip. Warping costs the same as drawing the un-warped layer, which is why the preview keeps up with typing even on mid-range Android.

Only through the fields you expose. Merchants build the layer stack; customers fill it in. That is deliberate — it keeps every order inside a layout you have already checked against the print area.

No. Rules are configured in the admin and evaluated by the storefront runtime. Conditional visibility is available on Studio and Atelier.

Any Online Store 2.0 theme supports app blocks, which covers every theme Shopify has shipped since 2021 and every current paid theme. For older vintage themes we install with a snippet instead — write to us and we will look at your theme.

The import summary lists it as missing and the layer keeps its metrics. Upload the licensed font to the brand library and re-import that layer — we never substitute a lookalike behind your back.

No — that is the reason for the fee-variant design. Fees are real line items on real products, so Shopify's own discount, tax and abandoned-cart logic applies to them like anything else in the cart.

Fee variants are removed and the block stops rendering. Your products, orders and order artwork stay exactly where they are.

No. The switch from fee variants to Cart Transform is automatic and your option sets, templates and print pipeline are untouched.

The device is a field, not a template. One template carries the artwork; the device field selects the print dimensions, the cut-out mask and the wrap width. Adding next year's model is one row of configuration.

Yes, with a minimum resolution gate so a 400px avatar cannot be printed at A3. Uploads run through automatic moderation with an optional manual review queue.

The field carries a character limit per line, with a live counter, so the customer sees the constraint while typing. Above the limit the item cannot be added to cart — the print worker never receives an unprintable order.

Start with one product rather than the catalogue: rebuild your bestseller as a Customei template, put it live behind the theme block, and judge the switch on that one product before you move the long tail.

Above roughly twenty thousand personalized items a month we open a custom plan on top of Atelier, and optional self-hosting is part of that conversation.
