--- title: "Frequently asked questions - Workflow Documents" description: "Common questions about generating PDF documents from Shopify Flow: templates, languages, the download link, plans and usage, the developer API and data handling." canonical: "https://docs.workflow-documents.app/faq" --- # Frequently asked questions Answers to the questions we expect most often. If yours is not here, [Troubleshooting](https://docs.workflow-documents.app/troubleshooting.md) covers errors in detail, and [Support](https://docs.workflow-documents.app/help/support.md) has every way to reach us. ### Do I need Shopify Flow? For automatic documents, yes. Flow runs your automation, and Workflow Documents adds a **Generate document** action to it. Flow is free from Shopify. Without Flow you can still generate documents through the Developer API. See [Set up the Generate document action in Shopify Flow](https://docs.workflow-documents.app/set-up-the-generate-document-action-in-shopify-flow.md). ### Which documents can I create? Any document about one order, one product or one customer: invoices, packing slips, delivery notes, order confirmations, product data sheets, customer summaries and your own. Ready-made templates exist for an invoice, a packing slip, a product data sheet and a customer summary. See [Create your first template](https://docs.workflow-documents.app/create-your-first-template.md). ### Do I need to know HTML? The ready-made templates work without touching the code: add your logo, colors and company details in Settings and they are yours. To change the layout or print more fields you edit HTML, CSS and Liquid, with a live preview next to the code. See [The template editor](https://docs.workflow-documents.app/template-editor.md). ### Can I use the Liquid from my Shopify theme or from Order Printer? The language is the same, the data is not. A document template sees the objects listed in [Template variables and Liquid](https://docs.workflow-documents.app/template-variables-and-liquid.md), with names close to Shopify's own, such as `order.line_items`. Theme objects, theme filters and includes are not available, so a template from elsewhere needs adapting. ### Is the PDF attached to the email or to the order? No. The action returns a download link that is valid for 7 days, and you put that link into an email or a request in the next Flow step. The PDF is not attached to the order in Shopify. ### What happens after the 7 days? The link stops working. The PDF itself stays downloadable on the **Documents** page for as long as your plan keeps it. See [Document history and downloads](https://docs.workflow-documents.app/document-history.md). ### What does it cost? **Free** includes 100 documents per rolling 30 days. **Starter** is $9 per month for 1,000 documents, and **Unlimited** is $29 per month without a limit. Every plan includes all features, and there are no charges per document. See [Plans and pricing](https://docs.workflow-documents.app/plans-and-pricing.md). ### Do previews count toward my plan? No. The live preview, **Preview PDF** and downloads in the app are free. Documents generated by Shopify Flow and through the API count, and a failed document does not. See [Plans and pricing](https://docs.workflow-documents.app/plans-and-pricing.md). ### What happens when my allowance is used up? Further documents are refused until the rolling 30-day window frees up, and the Flow step fails with a message that says so. To keep generating right away, change to a larger plan. Nothing is billed on top of your plan. See [Plans and pricing](https://docs.workflow-documents.app/plans-and-pricing.md). ### Can one template serve several languages? Yes. Add languages to a template, each with its own HTML and file name. The document is rendered in the language of the action's **Language** field, else the customer's language, else the template's main language. A new language starts as a copy that you translate yourself. See [Templates in several languages](https://docs.workflow-documents.app/languages.md). ### Can I use my own fonts? Yes. Upload WOFF2, WOFF, TTF or OTF files in **Settings**, or pick a built-in font or a Google font. See [Branding your documents](https://docs.workflow-documents.app/branding.md). ### Can one template look different from my brand? Yes. The **Branding** tab of a template sets colors, fonts and font size for that template only. What it leaves empty uses your brand. See [Branding your documents](https://docs.workflow-documents.app/branding.md). ### Can I rename a template? Yes, but workflows find a template by its exact name. After renaming, update the **Template name** in every Generate document action that used the old name, or those steps fail. ### Does a Flow retry generate the document twice? No. If Flow retries a step that already succeeded, we return the earlier result instead of generating again, so it is not counted twice. See [Set up the Generate document action in Shopify Flow](https://docs.workflow-documents.app/set-up-the-generate-document-action-in-shopify-flow.md). ### Can I generate a document for an old order? For orders of the last 60 days. Shopify does not give apps access to older orders by default, so a document for an older order fails with an order not found message. See [Troubleshooting](https://docs.workflow-documents.app/troubleshooting.md). ### Can I create documents for draft orders, fulfillments or collections? Not at the moment. Templates render orders, products and customers. If you need another kind, [Request a feature](https://docs.workflow-documents.app/help/request-a-feature.md). ### Are invoice numbers generated? The app does not keep a number sequence of its own. A template prints what the order carries, for example the order number with `order.name`. If your country requires a separate, gapless invoice number, check with your accountant whether the order number meets that requirement. ### Can I generate documents from my own code or an AI assistant? Yes. The **Developer** page issues API keys for a REST API and an MCP server. They manage templates and branding and generate documents. Documents generated this way count toward your plan. See [Developer API and MCP](https://docs.workflow-documents.app/developer-api-and-mcp.md). ### Where is my data stored? In the European Union. To render a document, the app reads the order, product or customer from your store at that moment. The generated PDF is stored for your plan's retention and then deleted.
