Sign Customiser can now carry your customer’s chosen scene background through to the product image, so the picture they see in their cart and order matches the design they built — sign, background and all.

What’s Changed

• Backgrounds follow the design into the cartWhen a shopper picks one of your scene backgrounds in the visualiser, the product image can now use that same background instead of the default product photo.
• True-to-life sizingIf a background image has a real-world width set, the sign is scaled proportionally against it, so a small sign looks small and a large sign fills the scene — giving customers a realistic sense of what they’re ordering.
• You’re in controlThe feature is off by default. Turn on “Use the selected background in the product image” from the Scene Editor page whenever you’re ready — existing customisers keep working exactly as before.
• Works hand in hand with size scalingThe option pairs with “Scale visualisation with size”, so the product image only uses the scene background when the visualiser is showing the sign at its true scale.

Sign Customiser can now send customers an automatic confirmation when they submit a quote request or custom design form. Each customiser has its own opt-in setting, so nothing is sent until you turn it on.

What’s Changed

• Automatic acknowledgementsGive customers immediate confirmation that their quote request or custom design submission has arrived
• Separate wording for each formWrite a different message for quote requests and custom design submissions, with editable subject lines and email bodies
• Your branding and reply addressUse your store’s email branding and route customer replies back to your inbox
• Clear sending statusSee whether each submission flow is sending, with a direct link to fix any missing setup
• Safe template controlsBrowse customer-safe variables and reset the wording to Sign Customiser’s default at any time

Shopify discounts can now target every sign generated by Sign Customiser, or only the signs created through one customiser. New products join the right Shopify collections as they are created, so collection-based discount codes and automatic discounts apply on the shopper’s first cart or checkout attempt.

What’s Changed

• Target every generated signSign Customiser maintains a Sign Customiser Products collection for your store
• Target one customiserEach customiser gets its own collection when it creates its first product. The collection uses the customiser’s name and follows later name changes
• Apply discounts without a delayNew signs join both collections during product creation, so Shopify can apply collection-based discount codes and automatic discounts straight away
• Build your own Shopify automationsEvery new product also carries the sign-customiser-generated tag and a tag tied to its customiser
• Keep broad offers broadDiscounts set to all products still work as before

Shopify product discounts apply on top of the price set by your customiser. If more than one Shopify product discount overlaps, Shopify applies the better discount rather than adding the discounts together.

Shopify Starter and Retail do not support collection management. On those plans, discounts set to all products still apply to generated signs, but collection-based targeting is unavailable.

Sign Customiser now gives each newly generated Shopify product a product type that matches its sign category. This makes it easier to build collections, shipping rules and other Shopify automations for different kinds of signs.

What’s Changed

• Product types now match the signNew acrylic, metal, stencil, wooden, aluminium, braille, wood-frame and lightbox products receive their own clear product type.
• Neon remains familiarNew neon products keep the existing Custom Neon product type, so established neon workflows continue to work.
• Existing products stay unchangedThe new product types apply when Sign Customiser creates a product. Products already in Shopify are not renamed.

Sign Customiser now lets you set a different price for each letter position in Simple Letter and Advanced Letter customisers. You can include the first few letters at no extra cost, build a stepped pricing schedule, and charge longer signs accurately without configuring every possible text length.

What’s Changed

• Choose how letters are pricedKeep one consistent price for every letter or select Price by position for a more flexible schedule
• Include free lettersSet any position to zero when you want early letters covered by the sign’s base price
• Cover longer text automaticallyOnce a customer types beyond your configured schedule, every later letter uses the final price in the list
• Control up to 100 positionsAdd positions as needed, with each new position copying the last price to make longer schedules quick to set up
• Handle multiple lines predictablySimple Letter restarts at position 1 on each configured line, while Advanced Letter continues one sequence across the whole sign
• Switch modes without losing workSign Customiser keeps both pricing methods, so you can change modes and return to your saved values later

Choose Price by position beside the existing letter-pricing controls, then open the position editor for the size or line you want to configure.

Sign Customiser now measures every custom shape you upload — plaques, circles, stars, pill shapes — and uses its real proportions everywhere: on screen, in the price, and in the file your manufacturer cuts from. Upload any outline and trust that what your customer sees is what they get — a rounded square looks genuinely square, a circle is truly round, and the preview matches the finished sign.

What’s Changed

• True to real-life dimensionsA rounded square is now genuinely square on screen, not a stretched rectangle wearing the name. Every shape is drawn at the exact proportions it will be manufactured at, so the preview, the quoted size and the sign that arrives all agree.
• Pixel-accurate to the shape you uploadEvery custom shape is measured against its true outline, so the shape your customer sees in the customiser matches the file you uploaded exactly. No more small drifts between the preview, the quoted size and the finished sign.
• Proportions are never distortedA custom shape owns its own ratio. Your customer sets one dimension and the other follows automatically, so a circle stays a circle and a star stays a star at every size — there is no way to stretch or squash a shape out of proportion.
• Custom sizing only for shapesPreset size cards no longer appear once a custom shape is selected, because a preset would either have to match the shape’s ratio or distort it. Customers drag the size slider or type a width or height, and a padlock confirms the proportions are fixed by the shape they chose.
• Pricing that matches the real shapeSigns priced by area are now worked out from the shape’s true measured dimensions rather than an approximation, so the quote reflects the material actually being cut.
• Manufacturing files that match the designOrders for a custom shape include a precise cut path for the exact outline and size the customer chose, with lettering converted to clean cut lines — ready to go straight to production.
• Clearer guardrails when you set a shape upBorder margins and custom shapes are mutually exclusive, because a shape already owns its proportions, and the size settings now say so plainly instead of quietly ignoring the value. If a shape’s padding or your minimum and maximum size limits leave it with no usable size, Sign Customiser names the shape and tells you what to change.
• Shape wording in your own voiceThe new customer-facing messages — the finished size readout, the note that proportions are fixed by the chosen shape, and the size-adjustment prompts — are all editable per customiser and translatable like every other label.

We’ve refined Sign Customiser’s stencil sign around the details that matter when a sheet reaches production. The live preview now separates the usable design area from the overspray border, measures the true letter height of every line and keeps the finished sheet size visible. Pricing and eligible production files use those same bordered dimensions.

What’s Changed

• One clear border allowanceRectangular stencil sheets use the configured overspray border as the single source of padding around the design. A dashed guide marks where the usable design area ends, and the included demo uses a 1 inch border for 1 to 2 inch letters, 2 inches for 3 to 7 inch letters and 3 inches for 8 to 12 inch letters.
• Letter height means the letters themselvesSizing follows the visible glyph height instead of counting the full line box or the gap between lines. Every text line gets its own on-canvas height guide, so a 3 inch choice produces 3 inch letters on each line.
• Separate finished-sheet measurementsOverall width and height rails sit outside the sheet and include the full border. Customers can see the size you will manufacture without confusing it with the letter-height guides inside the design.
• One size from quote to cutThe live price, product image, order details and manufacturer handoff agree on the bordered sheet size. Compatible text-only designs carry the same physical dimensions into calibrated SVG and optional DXF files.
• A complete demo in one clickMerchants can install a ready-made stencil customiser with 12 letter-height tiers, tiered borders, three Mylar materials, four stencil-safe fonts, exact-height controls and production file settings already configured.

Sign Customiser now gives merchants a stable CSS class for each part of the customer customiser. Existing custom CSS can target controls and states more precisely, without relying on generated class names that may change after an update.

What’s Changed

• More complete CSS coverageStable classes now cover the customiser’s controls, forms, pricing details, previews, loading states and other visible elements
• Reliable pop-up stylingModals, tooltips and popovers have dedicated classes, including elements that render outside the main customiser container
• Predictable state selectorsSelected, open, active, disabled and error states use consistent class names where those states are available
• Embed wrapper controlsShopify theme embeds and website integration wrappers now expose stable classes for their containers, loading screens, modals and validation messages
• Safer saved CSSSign Customiser now handles merchant CSS and customiser setup data more safely when loading embedded, hosted and preview customisers

Sign Customiser’s previous-generation public API is now deprecated. Existing integrations continue to work, but developers should move to API v3 before the scheduled 22 January 2027 Sunset.

The new v2 to v3 migration guide maps every previous-generation operation to its v3 replacement. It also covers scoped Store-bound keys, pricing field changes, webhook subscriptions, order and product writes, error handling, pagination, and a safe cutover sequence that avoids duplicate writes.

Deprecated responses now include standard Deprecation, Sunset, and Link headers. These make the timeline and migration guide visible to API clients without changing existing response bodies, status codes, validation, or authentication behaviour.
