Premium modular short-stay platform — WordPress + MotoPress + Portuguese fiscal integrations

## Project overview I'm looking for a senior WordPress developer to build a custom booking platform for a premium short-stay property in northern Portugal (Marco de Canaveses). The property is a 4-bedroom house rented under a **modular configuration system**: instead of single rooms, the property is sold as 6 pre-defined configurations (whole house, left wing, right independent suite, individual rooms), with rules about which configurations can coexist on the same dates. Up to 4 different guests may share the property at the same time. A visual mockup is available at [login to view URL] for reference. **IMPORTANT: the mockup is for visual reference only — it was generated with Lovable (React/[login to view URL]) and is NOT to be imported as code.** The implementation must be in WordPress + PHP. ## Tech stack (decided, not negotiable) - **WordPress 6.x** (latest stable) on Linux VPS (Hetzner Cloud) - **MySQL** database - **MotoPress Hotel Booking** plugin as base reservation engine - **PHP custom code** for all business logic that the plugin doesn't cover - **Polylang** for multi-language (PT/EN/FR) - **Astra or Kadence** theme as base, with custom child theme Please do NOT propose alternative stacks (Node.js, Laravel, etc.). The stack is locked. ## Core features 1. **Modular reservation engine** — 6 pre-defined configurations modeled as MotoPress accommodation types, with a custom incompatibility matrix (PHP hooks). System must enforce that incompatible configurations cannot be booked on overlapping dates. 2. **Maximum 30-day rental period** per booking, validated server-side. 3. **Up to 4 concurrent reservations** on the same dates (when configurations are compatible). 4. **Seasonal pricing** — high/medium/low seasons with configurable dates and prices per configuration. 5. **Discount coupons** and email-based discounts (e.g., specific email domains get a discount). 6. **Guest account system** — registration, login, profile, NIF field, booking history, invoices. 7. **Payment integration**: - Stripe (cards, including UE/UK/international rates) - IfthenPay (Multibanco and MB WAY) — custom gateway 8. **Automatic invoicing** via InvoiceXpress API: - Invoice generated automatically on payment confirmation - Includes mandatory AT QR Code and ATCUD (handled by InvoiceXpress) - PDF sent to guest by email - Stored in admin panel - Auto credit notes for cancellations 9. **Self-service for guests**: - Modify dates (within rules) - Cancel booking with automatic refund - Resend access code - Help center with contextual FAQ 10. **Smart lock integration (Nuki Web API)** — automatic generation and expiration of access codes per booking, sent via email and SMS (Twilio). 11. **Review system** — automatic email 24h after check-out inviting review, public display with aggregate rating. 12. **Multi-language site** (PT, EN, FR) via Polylang. 13. **Admin dashboard** (WP-Admin with customizations) — bookings overview, calendar, pricing management, invoice list, guest management. 14. **Automatic emails** (transactional via Resend or Postmark) — confirmation, check-in instructions, access code, post-checkout review request. NOTE: AIMA / SIBA reporting is OUT OF SCOPE — the client will handle it separately. ## Required experience - **5+ years senior WordPress development** (not just plugin installation) - **MotoPress Hotel Booking** previous projects (please link) - **Portuguese fiscal integrations** — InvoiceXpress, Moloni, or Vendus API experience - **Portuguese payment gateways** — IfthenPay or EuPago - **Custom WordPress plugin development** in PHP (not just child theme tweaks) - **REST API integration experience** (Stripe, third-party APIs) - **Working Portuguese language skills** (the site is in Portuguese; legal/fiscal context is Portuguese) - Bonus: Nuki Web API experience ## Deliverables - Production-ready WordPress installation on the VPS I provide - All custom code in a single custom plugin (well-documented, PSR-compliant) - Polylang configuration for PT/EN/FR - All 6 pre-defined configurations modeled and tested - All integrations fully functional in a staging environment first - End-to-end testing: booking → payment → invoice → access code → check-in → review - Setup documentation and a short Loom video walkthrough of the admin panel - 90-day bug-fix warranty after go-live ## Timeline - Estimated 7–8 weeks from kick-off - Milestone-based delivery (staging environment with reservation flow → staging with payments and invoicing → production deployment) ## In your proposal, please include 1. Links to 2 or 3 similar WordPress + booking projects you've completed 2. Specific experience with MotoPress Hotel Booking and at least one Portuguese fiscal system (InvoiceXpress/Moloni/Vendus) 3. Your proposed milestones and timeline 4. Total fixed price (please don't bid hourly) Proposals that look generic or copy-pasted will be ignored.
