I need to automate the full invoice flow between my Prestashop store and Facturalia or Billit. Every order completed in Prestashop should trigger an invoice that is pushed to Facturalia or Billit; once Facturalia or Billit processes or rejects it, the corresponding status must sync back to Prestashop so customers and staff always see the correct state. The Billit API allows two approaches—webhooks or polling—but I’m still weighing the pros and cons. Part of your mandate is to advise which path is the most stable and future-proof in a typical Prestashop environment and then implement it. There is currently no Prestashop plugin or middleware in place, so the module has to be built from scratch, installed, and documented. All relevant resources are available here: • API overview: [login to view URL] • Architecture diagram (PDF): [login to view URL] Facturalia documentation [login to view URL] (please use google translate as all the info is in Dutch) [login to view URL] Deliverables—acceptance criteria 1. 2 x Prestashop module that captures completed orders, converts them to Billit-compliant invoices, and sends them automatically via the chosen method. 1 for Facturalia and 1 for Billit. 2. Real-time (or near-real-time) status updates from Billit or Facturalia reflected in Prestashop’s back office. 3. Error logging and basic retry logic so failed sends are visible and recoverable. 4. Installation guide plus a short screencast or screenshots proving the integration works with a live test order. When you reply, include a detailed project proposal that covers the recommended integration method, high-level architecture, milestones, and any dependencies you foresee.

Hi [ClientFirstName], I’ve read your need to automate Prestashop invoices into Billit and sync status in real time. I’ve built multiple Prestashop modules and API integrations in PHP/MySQL, including invoicing and status sync with external services. My approach is webhooks-first (Billit → Prestashop) with a lightweight polling fallback for resilience. A new Prestashop module will trigger on order completion to create a Billit invoice, map order data (customer, items, taxes, currency), and push it via Billit API. I’ll store a small mapping table (prestashop_order_id, billit_invoice_id, billit_status, prestashop_status) and implement retry logic with limited attempts and error logging. Billit webhooks will update Prestashop back in near real-time, with a secure endpoint and signature check. An installation guide and a short screencast will prove the flow with a live test order. Milestones: architecture/env setup; module skeleton and order hook; Billit API integration; webhook endpoint and status sync; logging/retries/docs. Dependencies: Billit credentials, Prestashop access, hosting that allows inbound webhook. Proposed timeline: 2-3 weeks for a working prototype, then refinements. Prestashop version and hosting details? Billit environment (test or live) and credentials status? Primary integration method: webhooks with polling fallback or polling only? Which Prestashop order states should trigger invoice creation (e.g., Payment accepted, Order delivered)? Which data fields

Hi, Your project to automate invoice flow between Prestashop and Billit clearly taps into a critical operational need—seamless integration to ensure accurate, real-time status updates and order management. Having developed custom Prestashop modules integrating third-party APIs, I understand how crucial stability and future-proofing are for your invoicing workflow. I recommend using the webhook approach for the Billit API for its real-time status updates and reduced server load compared to polling, which can be less efficient and slower to reflect changes. My plan involves building a robust Prestashop module that listens to completed orders, transforms them into Billit-compatible invoices, manages sending with retry logic, and updates order statuses based on webhook callbacks. Architecture-wise, the module will interface directly with the Billit API using secure REST calls, handle asynchronous status updates via webhooks, and log errors in Prestashop’s database for transparency and recovery. Milestones include module development, thorough testing with live data, documentation creation, and delivery of installation guides plus demonstration screencasts. 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. Given your preference for stability and real-time updates, are you leaning more toward webhook-driven integration, or would you prefer we fully evaluate poll

Hello,I recommend using Billit webhooks with a polling fallback. Webhooks provide near-real-time status updates and are the most future-proof option, while polling ensures reliability if a webhook fails. I will build a custom Prestashop module from scratch that captures completed orders, converts them into Billit-compliant invoices, and sends them automatically. Invoice status updates from Billit will sync back to Prestashop, with logging and retry logic for errors. Deliverables include the module, installation guide, and screenshots or a short screencast showing a successful live test order. Azad

Hi, thanks for your job posting. I have read your description carefully and I am sure that I can build a custom Prestashop module that fully automates invoice creation and status syncing with Billit. I will first evaluate Billit webhooks versus polling and implement the most stable, future-proof approach for your Prestashop environment. Completed orders will be automatically converted into Billit-compliant invoices and sent without manual intervention. Invoice processing or rejection statuses from Billit will sync back to Prestashop in near real time. The solution will include clear logging, retry handling, and a resumable state system for failed invoices. I will ensure the module is clean, maintainable, and safe to re-run without creating duplicates. You will receive full installation documentation plus proof of a successful live test order. This integration will give your staff and customers accurate, always-up-to-date invoice statuses. Best regards. Jijo

Hello, I understand this is about fully automating invoicing, not just sending data one way. Every completed order must reliably generate an invoice, and whatever happens next—accepted or rejected—needs to be reflected back so staff and customers always see the correct status. I’ll build a custom solution from scratch, recommend the most stable approach for keeping both systems in sync, and implement it end to end. This will include clear status updates, visible error handling with retry logic, and straightforward documentation so nothing is hidden or fragile. You’ll also get proof of the full flow using a live test order. I’ve handled similar billing and finance integrations where accuracy and traceability matter. Happy to walk you through the approach, milestones, and any dependencies before we begin. Best regards, Sagar P. Senior Web & Mobile Developer | AI Integrate | Scalable SaaS Solutions
