Hi, You’re clearly trying to remove the hidden friction in your fulfillment flow: keeping Shopify as the single control center while Swiss Post and FedEx stay fully connected behind the scenes. I’ve built Shopify and PHP-based automation before, and this kind of admin-side workflow is exactly where careful API handling, order state logic, and clean UI matter most. I can build the public Shopify app with App Bridge and Polaris, handle partial fulfillments, customs automation, tracking write-back, timeline logging, label cancellation, and the sender/profile settings you described. I’ll also make sure the app structure is clean, documented, and ready for App Store review. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. I can start by reviewing the SoW and your Loom workflow, then map the API flow and fulfillment states before development begins. Do you already have API access and docs for Swiss Post/FedEx, or should I plan around getting those first? Thanks, Asad

@Rekhathakur

Hi, This is a highly specialized Shopify integration project, and after reviewing the requirements, I’m confident I can help architect and develop a robust public Shopify app that fully embeds Swiss Post and FedEx fulfillment workflows directly within the Shopify Admin experience. I have experience building custom Shopify applications, fulfillment integrations, carrier APIs, webhook-driven workflows, and admin interfaces using **Shopify App Bridge, Polaris, Node.js, React, and PostgreSQL**. My focus is on creating solutions that feel native to Shopify while maintaining reliability, scalability, and compliance with Shopify App Store requirements. A Few Technical Questions 1. Does Swiss Post provide all required label generation, customs, and cancellation endpoints through their API? 2. Will FedEx be used alongside Swiss Post on the same shipment workflows or as separate fulfillment methods? 3. Are there existing carrier account credentials already configured? 4. Will the app initially support a single Shopify store or multiple merchant installations? 5. Do you already have App Store publishing requirements defined? Proposed Workflow * Review SoW, Loom recordings, and current fulfillment process * Architecture and data model design * Shopify app foundation (App Bridge + Polaris) * Swiss Post and FedEx API integration * Partial fulfillment interface * Customs, CN22/CN23, PDDP, and EORI automation Best regards,

Hi! ~ I am a Shopify App Developer So I can build this custom Shopify public app with full fulfillment workflow integration. I have worked on Shopify apps using App Bridge and Polaris, including API integrations, order workflows, and automation inside the Shopify Admin. I am comfortable handling complex logic like partial fulfillments, customs automation (CN22/CN23), and carrier integrations. I will ensure: ~ Clean Shopify Admin UI for partial fulfillment and label handling. ~ Seamless Swiss Post + FedEx API integration. ~ Accurate tracking write-back and carrier mapping. ~ Automation for customs, signatures, and order timeline logs. ~ Scalable app settings and clean, well-documented code. Estimated timeline: 4–5 weeks Estimated budget: $2500 Quick question: Do you already have API access/credentials for Swiss Post and FedEx (including sandbox)? Happy to review your SoW and Loom videos and align on implementation.

Hi I can build a custom public Shopify app using Shopify App Bridge, Polaris, Shopify Admin GraphQL/REST APIs, OAuth, webhooks, and a secure backend in Node.js/Remix or similar. The main technical challenge is keeping fulfillment state, partial package quantities, label generation, customs documents, cancellation, and Shopify order status perfectly synchronized across Swiss Post, FedEx, and Shopify. My solution would use a structured fulfillment workflow with package-level item selection, carrier API abstraction, validation rules for CN22/CN23, PDDP, EORI, fallback currencies, and secure sender profile management. I would also implement smart tracking write-back, national carrier mapping, Economy shipment exceptions, Shopify Order Timeline logging, and fulfillment deletion on label cancellation. The app UI would live directly inside Shopify Admin with Polaris components so your team can complete the workflow without using the Swiss Post portal. I have experience with Shopify apps, API integrations, fulfillment automation, shipping labels, webhooks, admin dashboards, and documented hand-offs for internal teams. I will deliver clean documented source code, deployment-ready configuration, and walkthrough videos based on your SoW and current manual workflow. The architecture will be modular enough to support future carriers, new customs rules, and additional fulfillment automation without rebuilding the core app. Thanks, Hercules

@anirudhat

Eliminating the manual Swiss Post portal workflow with a native Shopify app is exactly the kind of complex integration I specialize in. I'll build this as a public Shopify app using Node.js with the Shopify App Bridge and Polaris UI, integrating directly against the Swiss Post Barcode/Webservice APIs and FedEx Ship API for label generation, customs automation, and tracking writeback. The partial fulfillment UI will hook into the Shopify Admin Orders page via app extensions, letting your team select line items per package, auto-generate CN22/CN23 forms based on declared value thresholds, and handle PDDP/EORI rules per destination country. Tracking updates will use carrier-mapped codes (USPS, Royal Mail, La Poste) written back via the Fulfillment API, with label cancellation triggering fulfillment deletion to cleanly reset order state. I'd love to review your SoW document and Loom videos — I can start immediately.

@doomshellsl

Hi, After reviewing the requirements, we noticed that this isn't a typical Shopify customization project. The objective is to replace a manual fulfillment process with a fully integrated workflow inside Shopify Admin, allowing your team to manage shipping, customs, tracking, and fulfillment actions without switching between multiple platforms. The complexity isn't limited to API connectivity. Features such as partial fulfillments, CN22/CN23 generation, country-specific PDDP rules, EORI handling, tracking-carrier mapping, fulfillment rollback on label cancellation, and timeline logging require careful planning around Shopify's fulfillment architecture and app lifecycle. The fact that you're already preparing a detailed SoW and Loom walkthroughs is a strong advantage because many of these workflows are highly business-specific. A couple of questions: • Will the app be installed exclusively on your store initially, or should the architecture be designed from day one to support multiple Shopify merchants through the App Store? • For Swiss Post and FedEx integrations, do you already have production API credentials and documentation access, or should sandbox setup and certification be included within the scope? The project appears well-defined and technically interesting, and we'd be interested in reviewing the SoW and workflow recordings before discussing implementation phases, timeline, and budget. Regards

@stelianrosca618

Hi, This is a well-specified app and the complexity is in the right places. These are all solvable but they need to be done carefully and in the right order. I've built Shopify apps with App Bridge and Polaris before so the admin UI embedded natively in the order page is familiar territory. The Swiss Post and FedEx API integrations are the more specialised piece - I'd want to review your SoW and watch the Loom videos of the current manual workflow before committing to a fixed timeline and budget. That's the right way to scope something this specific. The customs automation piece - CN22 vs CN23 based on value thresholds, PDDP rules for USA, FR, DE, AT — is where a lot of these projects go wrong if the country-specific rules aren't mapped out properly upfront. Happy to dig into that detail once I've seen the docs. Please share the SoW and Loom videos and I'll come back with a firm timeline and budget. Thanks.

@vladang

I can see the main goal here is removing the dependency on Swiss Post’s portal and turning the whole shipping flow into a native Shopify experience. I’d approach this by first building the Shopify embedded app structure with App Bridge and Polaris, then connecting the fulfillment logic with Swiss Post and FedEx APIs while keeping Shopify’s order state fully synchronized. The tricky parts are not just creating labels, but handling partial fulfillment, customs rules, PDDP variations, cancellation recovery, and tracking behavior correctly across different destinations. I worked on Shopify integrations for Ceevo and HL Fashions where reliability around external APIs and store workflows was critical, so I’d design proper validation, error handling, and logging from the beginning. One improvement I’d add is clear status visibility inside the order UI so staff always know what happened without checking logs. I’d like to review your SoW and Loom workflow to align the implementation details before starting.
