WordPress / WooCommerce Developer — Fancy Product Designer Configurator with Quote & Order Flow

MUST-HAVE: hands-on experience with the Fancy Product Designer plugin. This project is built around it — please do not apply without real FPD experience. ABOUT THE PROJECT We sell customizable products (e.g. branded baby items such as rubber ducks, bibs, rompers) to two customer types: manufacturers and clinics/businesses. We need a product configurator on our existing WordPress site where a customer personalizes a product, then either buys it directly (Stripe) or requests a quote that is emailed as a PDF. The configurator itself is the Fancy Product Designer plugin — we don't want a 3D engine built from scratch, we want it integrated, white-labeled and wired into the flow below. We already have a detailed spec, flow diagrams and a clickable prototype, which we'll share with the selected developer. WHAT YOU'LL BUILD Integrate and white-label Fancy Product Designer: set up 10 products, product color (preset palette + custom color code), a fixed logo upload area (image file only), and limit configuration to 1 product per order. Two entry pages using the same configurator: Manufacturer page: requires login (registered customers), quantity is fixed (predefined). Clinic / customer page: no login, quantity freely selectable with a minimum order. Two purchase paths after configuring: Buy now → order summary → Stripe payment → invoice. Request quote → quote PDF emailed → customer accepts → purchase (Stripe) → invoice. Quote handling: generate the quote, store it in the database (with the design preview image, product, color, logo) and email it. Manufacturer: email is known from the account; user just confirms or changes it. Clinic/customer: user fills a form (company, address, email, contact person, optional department). Invoicing: legally compliant invoices (German requirements: §14 UStG / GoBD, sequential numbers). Use an established invoicing plugin (e.g. Germanized / German Market / RechnungsPilot) rather than building from scratch. Invoice is triggered after online payment OR after a quote is accepted. Payment via WooCommerce + Stripe gateway (covers all products, not only configurator products). Internal admin overview of quotes / orders / invoices (who received what), showing the design image on accepted quotes. Link each saved configuration to its quote / order / invoice records. TECH STACK & SKILLS REQUIRED Strong WordPress + WooCommerce (custom post types, hooks/filters, plugin integration, templating). Solid PHP. Hands-on experience with Fancy Product Designer (or a comparable web-to-print / product personalization plugin) — required. Stripe integration via WooCommerce. Front-end / JavaScript for a clean configurator UX. German invoicing compliance, or proven experience setting up a compliant invoicing plugin. Clean, documented, maintainable code. TIMELINE 2 weeks NICE TO HAVE German language skills. Experience with product customizers / configurators and B2B quote-to-order flows. Good UI/UX sense. WHAT WE'LL PROVIDE A written specification (PDF), flow diagrams, and a clickable prototype of the full flow. Access to our WordPress environment and the Fancy Product Designer license. TO APPLY — PLEASE INCLUDE Start your proposal with the word "duck" so we know you read this post. 1–2 links to similar projects (configurator, WooCommerce, Fancy Product Designer, or quote/order flows). Your experience with Fancy Product Designer and Stripe. How you would handle German-compliant invoicing. A rough estimate (time + cost) and a short outline of your approach.
