Mountings

Add mounting options for your signs. Set optional prices and colours.

Restrict mounting options

You can prevent customers from selecting a mounting when incompatible colours and backboards are chosen. Follow these steps to do so: Navigate to the admin of Sign Customiser for your store Click on "Customisers" in the home menu Click on the customiser you want to edit From the left-hand menu, go to Sign Components → Mountings. Create or click on an existing mounting option. While creating or editing a mounting in the admin backend, simply select the incompatible colours and backboards from their respective dropdown inputs with labels "Colour Exclusions" and "Backboard Exclusions" (cut-out metal customisers will see "Panel Exclusions" instead of "Backboard Exclusions").

Create Shopify discounts for custom sign products

For most Shopify stores, scope an Amount off products discount to Sign Customiser Products or to a collection named after one of your customisers. Sign Customiser adds each new sign to the right collections during product creation, so eligible automatic discounts and discount codes work on the shopper's first attempt. Use the collections managed by Sign Customiser Do not build a smart collection from product type or tag rules for discount targeting. Shopify indexes those rules later, after the shopper may already have reached the cart or checkout.

Shopify discounts vs built-in price discounts

Compare Shopify discounts with Sign Customiser's built-in price discount. Learn where each discount appears and how to use both.

Additional Options

Use Additional Input Options to offer customers choices that are not covered by other settings. You can use these options to provide greater flexibility, such as selecting a power supply, specifying a delivery date, or adding notes to help with manufacturing. There are four input types, each offering different ways for customers to select or enter information: Yes / No Images Dropdown Notes Yes / No Displays two buttons side by side. Each option can affect the price and exclude specific colours. Images Displays a row of image buttons, allowing customers to compare options visually. Each option can have its own price. Dropdown Displays a traditional dropdown menu. This is useful for options with three or more choices, such as power supplies. Notes Displays a text field where customers can enter information. Their notes are included in the product data.

Change the instructions on the Custom Design screen

Change the main heading and step text shown beside a form on the customer-facing Custom tab, and find the right settings when you are currently editing the form itself.

Set the Custom Design Form as the Initial Screen

You can show a Custom Design Form as the initial screen of your customiser. The form then replaces the default sign visualiser.

Custom Design Forms

A Custom Design Form is a contact form built into Sign Customiser. Use it to collect custom design requests that the app cannot generate automatically. The form appears in the customiser: On desktop, it opens from the Custom tab. This is the default tab name. You can rename it. On mobile, it appears as a link below the selections. Customers can upload files, write messages, and use dropdowns, checkboxes and multiple-choice fields. They do not leave the page while they fill in the form. After they submit, they stay on the page unless you choose Redirect to a page (see Step 4). To quote customiser designs, use Quote Mode instead. For more information, read Quote Mode.

Add and Edit Custom Form Field Options

This guide shows how to add and edit the fields in a custom form. Every form must have a required Email field. New forms include this field.

Order fulfilment for in-house and outsourced production

Sign Customiser supports sign businesses that manufacture in-house, outsource production or use a mix of both. It captures the customer's design and passes the same specifications into the order and production handoff. Sign Customiser does not manufacture or ship the sign. You keep control of feasibility checks, supplier costs, approvals, production, delivery and installation.

Export orders as CSV via email

Export your Sign Customiser orders as a CSV file. You get an email with a private download link. Choose a preset or custom date range.

Supplier / Manufacturer Emails

Yes. You can use Sign Customiser when another company makes your signs. When an order is created from your store, Sign Customiser can send the order email automatically. It sends the email to the Receiver Email address set for that customiser. The supplier receives an ordinary email. The supplier does not need a Sign Customiser account. You keep control of the customer, the supplier relationship, the approval process and the delivery.

SVG, EPS and .AI files for manufacturing workflows

Sign Customiser can make an SVG file of the sign design. CNC machines can use this file. It also helps you trace the letters of the sign. This setting is off by default. To turn it on, follow these steps. Go to Settings → General Settings in your customiser. In the Generate SVG image of sign section, set SVG Image to Yes. Save your changes. For Simple Letter customisers, the app checks your fonts first. If a font cannot make an SVG, the app lists those fonts and keeps SVG Image at No. Change the fonts, then do steps 2 and 3 again. When SVG generation is on, the Shopify order shows the SVG file as the _svg line item property. The manufacturer email also has a link to the SVG file for each order that has one. You can also make EPS and Illustrator-compatible PDF files for the same design. The Illustrator-compatible PDF has an.ai filename. To turn them on, set EPS Image or AI Image to Yes. Each of these settings also keeps SVG generation on. The Shopify order does not include the EPS file or the AI file. They reach your manufacturer in the manufacturer email. The default manufacturer email template has a link for each file type. A link shows only when that file exists. If you changed the template, make sure that it has the epsPreviewLink and aiPreviewLink variables. Stencil customisers also have a DXF (.dxf) option in the same section. The admin describes it as an "AutoCAD-compatible outline file for CNC, laser, and plasma cutters". It needs SVG generation, so this setting also keeps SVG generation on. The manufacturer email has the DXF link in the dxfPreviewLink variable. The Shopify order does not include the DXF file. Lightbox customisers do not show the Generate SVG image of sign section. Cut-out metal signs use the same files. The SVG has the cut-path geometry for the metal panel. The EPS file and the Illustrator-compatible PDF file come from the SVG in the same way. Cut-out workflows need no new file types or template variables. All current plans include this feature: Seed, Growth and Ultimate. The older Pro, Boost and Premier plans also include it. The older Starter, Standard and Launch plans do not include it. On those plans, the Generate SVG image of sign settings show Plan Upgrade Required. For detailed instructions on how to use these files in your manufacturing process, read these guides. How to enable/disable SVG, EPS, and Illustrator-compatible PDF files for manufacturing How to find the SVG, EPS,.AI file in the Shopify How to include SVG, EPS, and Illustrator-compatible PDF files in manufacturer emails

Update manufacturer email address

You can add one more email address by appending each email with a ',' character e.g. 'first@email.com,second@email.com' To change the manufacturer email address do the following: Navigate to the admin of Sign Customiser for your store Click on "Customisers" in the home menu Click on the customiser you wish to edit From the left-hand menu, go to Email Workflows → Manufacturer Email. Add the email under Receiver Email and click Save on the bottom right to save the changes.

How to include SVG, EPS, and Illustrator-compatible PDF files in manufacturer emails

Add SVG, EPS, AI and DXF download links to the manufacturer email template.

How to enable/disable SVG, EPS, and Illustrator-compatible PDF files for manufacturing

Use these steps to turn SVG, EPS, and AI files on or off for manufacturing. Open the Sign Customiser admin. Click Customisers. Click the customiser that you want to change. In the left-hand menu, go to Settings → General Settings. Scroll down to the Generate SVG image of sign section. This section has three options: SVG Image — the scalable vector file for CNC machines and letter tracing. EPS Image — an EPS file that our server converts from the generated SVG. AI Image — a PDF file saved with an.ai filename. Stencil customisers have a fourth option, DXF (.dxf). This is an outline file in AutoCAD R12 DXF format. Lightbox customisers do not show this section. To turn on a file type for this customiser, set it to Yes. To turn it off, set it to No. Click Save at the bottom of the form.

How to find the SVG, EPS, .AI file in the Shopify

whenever a sign is ordered, you can access the order in Shopify admin page and download the SVG file by clicking on the _svg: "Link". To use this feature, you must have already enabled the SVG Files for manufacturing.

Hide Custom Sign Products from Your Storefront

Every time a user adds a custom sign to the cart, our app creates the sign as a "product" in your Shopify backend. This is necessary for handling and purchasing the sign. However, since these are customised products, you may wish to hide them from being displayed on your storefront. There are two ways to do this — you only need to pick one: Option 1 (recommended): Unlist your custom sign products. A single setting in Sign Customiser hides every new custom sign from your storefront automatically. No further work required. Option 2: Keep products as "Active" and hide them through your Shopify storefront settings. This involves a few configuration steps in Shopify.

Automatically deleting generated products

Delete unpurchased Custom Neon products automatically with the Mechanic app. Use Test mode first, then switch to Live mode.

Retrieve generated sign products not purchased

Every generated sign product carries the sign-customiser-generated tag. Purchased products also carry the npc_ordered tag. Combine those tags in Shopify's product search to find generated products that have not been purchased. Log in to your Shopify admin and open Products. Open the product search or filter field. Enter tag:sign-customiser-generated NOT tag:npc_ordered. Shopify now lists generated sign products that do not have the purchased-product tag. Filter one customiser Add its sc-customiser-ID tag to the search. You can also open the managed collection titled with that customiser's name before reviewing products. Do not filter only on product type Custom Neon. That type now identifies neon signs only. Acrylic, metal, stencil, wood, aluminium, braille, wood-frame and lightbox products use their own category-specific types.

How your products are created

Sign Customiser makes a product each time a customer designs a sign and adds it to the cart.

How SEO is treated for Custom Signs in Shopify

The custom signs created by our app are automatically hidden from search engines. We apply standard Shopify properties to ensure these products are excluded from SEO indexing. These includes settings recommended in the following guide: Create A Hidden Product in Shopify. These settings are applied automatically when a product is created by our app, and no additional action is required on your end.

Change Shopify Sale Channel for Products

You can change the sales channel that a product generated by a sign customiser is assigned to by following these steps. Navigate to the admin of Sign Customiser for your Shopify store. From the home page, click Tools & Settings. Click Integrations and Webhooks. Click on the Shopify integration. Click Edit Integration in the top right corner. Select the Sales Channel you wish to automatically publish to by clicking on the Publication select option and choosing one. Click Save in the modal.

Autogenerate SKU for sign products in Shopify?

Our app generates a new product in Shopify for every custom sign added to the cart by a customer. While the app does not assign SKUs automatically, you can implement an automatic SKU generation system using a third-party app. Below is a step-by-step guide to help you set this up.

Free Shipping for Custom Products in Shopify

If you are looking to provide free shipping for your custom sign products generated by our app, you might face challenges with Shopify's default settings. Shopify does not currently support assigning Shipping Profiles to product types or collections—only to specific products. This limitation can complicate setting up free shipping for products created by our customiser. While "free shipping discounts" exist in Shopify, they do not offer conditional rules to restrict the discount to specific product types or collections. How to identify generated sign products Prefer the Sign Customiser Products collection or the sign-customiser-generated tag. To target one customiser, use its collection or the sc-customiser-ID tag. Product type is only a fallback: neon remains Custom Neon, while other categories use Custom Acrylic Sign, Custom Metal Sign, Custom Cut-out Metal Sign, Custom Stencil, Custom Wooden Sign, Custom Aluminium Sign, Custom Braille Sign, Custom Wood Frame Sign and Custom Lightbox.

Getting Started with the Simple Letter Model

The Simple Letter pricing model is for merchants who sell signs in standard widths or heights with simple pricing (for example 40 cm, 60 cm and 80 cm). You set prices by size, character count, and number of lines. If you need more flexible pricing and dynamic size scaling, see the Advanced Letter pricing model.

Sizes – Simple Letter Model

Sizes in the Simple Letter Model are based on your size strategy: fixed width or fixed height combined with the maximum characters per line and maximum number of lines allowed for each size.

Pricing - Simple Letter Model

This Sign Customiser guide covers Pricing - Simple Letter Model with the steps and context you need to complete the workflow.

Fonts - Simple Model

Before configuring fonts, make sure you have already set up your Pricing and Sizes sections. Fonts in the Simple Letter Model rely on these settings to accurately calculate sign dimensions and pricing.

Request Essential Information – Simple Letter Model

This guide explains how to collect the information you need from your manufacturer to set up the Simple Letter Model customiser.

Getting Started with the Advanced Model

The Advanced Letter Model is for merchants who need flexible pricing and scalable sign dimensions. The Simple Letter Model uses predefined sizes. The Advanced Letter Model calculates the dimensions and the price from the selected font, text, and size. This guide shows the main steps to build an Advanced Letter Model customiser. First, collect information from your supplier. Then set up Pricing, Sizes and Fonts.

Sizing - Advanced model

This guide explains how to configure Sizes for the Advanced Letter model. Each size has a Size Scale Multiplier. The multiplier scales the sign by a fixed factor from its base size. The base size comes from the font's minimum letter heights.

Pricing - Advanced letter model

Pricing in the Advanced Letter Model lets you combine several calculations into a price that matches your real production costs. When you choose Letter Material Cost, this model works out the cost from the material length each letter needs. The system measures the outline of every character, takes half of that length as an estimate of its midline (centreline) path, and multiplies it by your material rate. This guide shows how to set up Pricing for the Advanced Letter Model. Works with AI Sign Designer The Advanced Letter Model supports AI Sign Designer for neon signs and channel letter signs (Acrylic and Metal). The system measures an AI-generated SVG design in the same way as typed text. It measures every shape in the converted SVG, except a UV-printed face. For each shape, it takes half of the outline length as an estimate of the midline (centreline) path. A UV-printed face adds no material length, letter price or shipping. The system prices the measured length with your Letter Material Cost. To enable AI Sign Designer on an Advanced Letter customiser, see How to Enable AI Sign Designer.

Fonts - Advanced Model

This guide explains how to configure fonts for the Advanced Letter Model, assign pricing models, adjust font spacing, and test measurement accuracy.

Letter Material Cost

Letter Material Cost is a pricing method used in the Advanced Letter Model. It calculates the price of letters based on the actual amount of material required to produce them. Key Benefits: Accurate pricing: Charge based on the actual material used. Font-sensitive pricing: Complex fonts use more material and thus cost more. Flexible pricing tiers: Set different material costs for different sign dimensions. Real-time calculations: Prices update as customers change their text or fonts. AI Sign Designer compatible: The same calculation can be used for AI-generated SVG designs.

Understanding Font Measurements in the Advanced Letter Model

This guide explains how and what you need to consider when setting the minimum font size in the Advanced Letter model.

Manually calculate shipping cost value

To do these calculations yourself, first must have your shipping cost matrix provided to you by your supplier/freight company. The formula to calculate the shipping cost per centimeter squared based on a defined cost per measurement is as follows. For the current size range, you are editing the price formula; you should match the range limit value with the step in your shipping cost matrix and retrieve the cost price value. E.g. You have set a max size range that was 75cm, and in the shipping cost matrix, you have found the cost price for 75cm by 75cm to be a value of $98.00 Dimensions:75cm by 75cm Price:$98.00 Calculation:98 / (75*75) = $0.017 per centimeter~ number was rounded to 3 decimals

Determine Material Cost from Average Cost per Letter

If your supplier provides an average cost per letter instead of a material cost per centimetre or inch, you can use the Advanced Letter Model to determine an appropriate Letter Material Cost. This guide will show you how to calculate the average material length used by a font and use this information to determine the material cost per centimetre.

Request essential information - Advanced model

This guide explains how to collect the information required from your manufacturer to configure the Advanced Letter Model customiser.

Get your shipping cost matrix

This Sign Customiser guide covers Get your shipping cost matrix with the steps and context you need to complete the workflow.

Test Sign Measurement Accuracy

Use this guide to test how accurate the measurements of a font are. Make a sample SVG of any text in any font. Measure the width, height and material length in Adobe Illustrator. Then compare these values with the customiser.

Sizing - Frame Fit Model

The frame (outer edges of a sign) is the primary factor for a sizing. “Outer edges” refers to the full boundary or perimeter of your sign. In other words, it’s the total width and height measured from the very leftmost point to the rightmost point and from the topmost point to the bottommost point of the finished sign. By always measuring from the outermost tips of a sign, you’ll get a clear and consistent measurement for quoting, production, and installation. Cut-out metal signs also use Frame Fit sizing. For Mode B (AI silhouette) cut-outs, the bounding box of the AI-generated shape drives the size.

Pricing - Frame Fit model

Frame Fit prices a sign from its width and height. With a Volumetric parcel, the shipping charge also uses the depth and the packaging allowances. Frame Fit adds no charge for each letter. A Frame Fit pricing is not tied to a font. A Frame Fit customiser uses one pricing. Cut-out metal signs also use Frame Fit pricing. The width and height of the sign control the calculation. Lightbox, Braille, Aluminium Plate and Wood Frame customisers also use Frame Fit. For Neon Letter, Channel Letter and Wood Letter signs, you choose Frame Fit when you create a customiser. On the How do you price your signs? step, select Price per square meter/foot. For Metal Cut-Out, Lightbox, Aluminium Plate, Braille and Wood Frame signs, Frame Fit is set for you. The step does not show.

Frame Fit Model

Frame Fit lets customers choose a sign width and height. For a Lightbox, customers also choose a depth. A size boundary sets the sign's base price. You can add component and mounting charges. A separate parcel calculation can add a shipping charge. It can also send weight to Shopify.

Legacy: Fixed Height model (migrate to Simple Letter)

Important: The Fixed Height model is no longer available. You cannot choose the Fixed Height model when you create a customiser. Use the Simple Letter model. Set Size Strategy to Fixed Height - Width scales dynamically, and set Multi-line height measurement to Letter height. Enter the same height you used for the Fixed Height size, and the sign has the same size. Prices can differ between the two models, so check your prices after you migrate. If you have a Fixed Height customiser, the Customisers list shows a Migrate badge on it. The customiser page shows Action required: migrate this customiser to the Simple Letter model. Create the customiser again with the Simple Letter model. Do not duplicate it, because a copy of a Fixed Height customiser is also a Fixed Height customiser. For the steps, read Sizes – Simple Letter Model. A fixed height model is a collection of sizes. Each size has a set height. For example, Small is 10cm, Medium is 20cm and Large is 30cm. This article uses centimetres. For each size, you can set these parameters: The height The minimum number of characters The maximum number of characters on each line The number of lines of text that the size allows In the legacy model, the app scales each size so that its tallest line has the height you set. A single-line sign has one line, so that line is the tallest line. Illustration: one line with a height of 50cm.

Pricing - Fixed Height Model (Legacy)

The Fixed Height model is a legacy pricing model. Sign Customiser does not offer it for new customisers. You cannot change an existing customiser to this model. A copy of a customiser on this model stays on this model. This article is for customisers that already use it. A customiser on this model shows the banner Action required: migrate this customiser to the Simple Letter model. The Customisers list shows a Migrate badge for it. For a new Neon Letter Signs, Channel Letter Signs or Wood Letter Signs customiser, use the Simple Letter model. On the Pricing step, choose Fixed height per size (badged Simple ). Stencils and Address Sign Numbers have only the Simple Letter model. For them, the create flow skips the Pricing step and sets fixed height sizing without showing that option. To move an old customiser, create a new customiser in the same way. Keep Include demo data on, which is the default. If you turn it off, open the Sizes page and set Size Strategy to Fixed Height - Width scales dynamically on each size. For more information, see Pricing - Simple Letter Model and Sizes – Simple Letter Model.

Tracking events for ad conversions

A custom JavaScript event fires after a form submission or a successful Shopify cart addition. Use these events for ad tracking, CRM data, or storefront scripts. This article also shows how to save a ShareLink with a cart. Starter, Standard, and Pro plan families, including their yearly variants, do not receive the tracking events in the List of events section. One exception applies: a Shopify iframe embed can still send add-to-cart events. This restriction does not apply to ShareLink events. ShareLinks need a plan that includes sharing. Note: The form:submitted webhook was deprecated on 24 August 2026. It continues to send the same payload on every submission. There is no cut-off date. For a new integration, read submissions from the quotes API. The API also returns submission history.

Send Google Ads click IDs to your CRM

Sign Customiser stores the Google Ads click IDs (gclid, gbraid, wbraid) of each form submission. Read them from the quotes API, a webhook, merchant emails or JavaScript events, then report offline conversions back to Google Ads.
