## 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.

Hello, With 15+ years of experience, I can deliver your custom WordPress booking platform for the premium short-stay property in Marco de Canaveses. Using MotoPress Hotel Booking as the base, I’ll implement the modular configuration system with PHP hooks, enforce incompatibility rules, and integrate Stripe and IfthenPay for payments. I’ll also connect InvoiceXpress for automatic invoicing, Nuki API for smart lock codes, and Polylang for PT/EN/FR multilingual setup. Would you prefer Elementor for flexibility or Kadence for lightweight performance? I’ve done similar work with great success and confident to fulfill your requirements. Let’s talk.

Hello, I understand you need a senior WordPress build for a premium short-stay house in Marco de Canaveses using WordPress, MotoPress, Polylang, PHP, and a custom plugin. I can build the 6 modular accommodation configurations, add the PHP incompatibility rules, max 30-day validation, shared occupancy logic, seasonal pricing, coupons, guest area, Stripe, IfthenPay, InvoiceXpress, Nuki, Twilio, emails, reviews, and admin tools. I will keep the Lovable mockup only as a visual guide and build everything cleanly in WordPress/PHP. My plan is to first finish staging with the booking rules and calendar, then payments and invoicing, then Nuki/SMS/emails, then full testing and production launch. I can work with fixed milestones over around 8 weeks and include setup docs, Loom walkthrough, and 90-day bug fixing after go-live. I can share private links to similar booking/API WordPress work in chat due to client NDAs. Can you confirm if you already have active API accounts/credentials for InvoiceXpress, IfthenPay, Stripe, Nuki, Twilio, and Resend/Postmark, or should setup support be included? Do you want refunds and cancellation rules to be fully automatic for all payment methods, or should some refunds need admin approval? Do you already have the exact 6 configuration names, coexistence matrix, season dates, and prices ready in a document? Should the guest self-service date modification allow price changes and extra payments/refunds automatically? Best regards,

Hello, Hope you are doing well, I understand you need a custom WordPress booking platform for your modular short-stay property in Marco de Canaveses using the exact stack specified — WordPress, MotoPress Hotel Booking, PHP custom logic, Polylang, and Astra/Kadence — with advanced compatibility rules, concurrent booking handling, seasonal pricing, and server-side reservation validation.

Hello, I’d build this exactly within the locked WordPress/PHP stack: WordPress 6.x, MotoPress Hotel Booking as the reservation base, Polylang for PT/EN/FR, Astra/Kadence child theme, and one well-structured custom plugin for the business logic and integrations. The key technical area is the modular booking model. I would implement the six configurations as MotoPress accommodation types, then enforce the incompatibility matrix, 30-day maximum stay, concurrent compatible bookings, seasonal pricing and discount rules server-side through custom PHP hooks, not only UI restrictions. For the operational flow, I’d structure the custom plugin around clear services: booking rules, Stripe/IfthenPay payments, InvoiceXpress invoicing/credit notes, Nuki access code generation, Twilio/transactional emails, guest account/self-service, reviews, logs and admin visibility. Before final delivery, I’d test the full chain in staging: booking → payment → invoice → access code → check-in instructions → review request. I’d also document setup, admin usage, API credentials, hooks and maintenance points. I would first validate sandbox/API access for IfthenPay, InvoiceXpress and Nuki to confirm all edge cases before production. Nico – widuIT - Top Freelancer LATAM

I've built three WordPress + MotoPress Hotel Booking platforms with modular room logic similar to your 6-configuration coexistence model. The incompatibility matrix (whole house vs. partial bookings) is something I've implemented via custom PHP hooks on MotoPress's booking validation. Approach: 1. Each configuration as a MotoPress accommodation type, mutual exclusivity enforced via PHP hooks on mphb_check_booking_availability with a custom incompatibility matrix in post meta. 2. InvoiceXpress integration for Portuguese fiscal compliance (AT tax authority). Experienced with Moloni too. 3. IfThenPay for Multibanco/MB WAY + Stripe for international cards, auto-triggering fiscal documents. 4. Polylang PT/EN/FR with translated booking flows, emails, and invoices. 5. Nuki Bridge API for automated access codes tied to confirmed bookings. Milestones: - M1 (Wk 1-2): Staging, theme, MotoPress config + incompatibility matrix - M2 (Wk 2-3): Booking flow, seasonal pricing, calendar sync - M3 (Wk 3-4): Payments + InvoiceXpress fiscal automation - M4 (Wk 4): Nuki, Polylang, end-to-end testing Can share staging access to a similar MotoPress booking platform I built for a Portuguese property.

Hi I can build your WordPress modular booking platform using WordPress 6.x, MotoPress Hotel Booking, custom PHP plugin development, Polylang, Stripe, IfthenPay, InvoiceXpress API, Nuki Web API, and Twilio/transactional email integrations. The main technical challenge is enforcing the custom configuration compatibility matrix, 30-day booking limit, concurrent reservations, seasonal pricing, payment-to-invoice automation, and smart-lock access flow without breaking MotoPress core behavior. I can implement the custom business logic inside a well-documented PHP plugin, configure all 6 accommodation configurations, integrate multilingual PT/EN/FR content, and test the full booking --> payment --> invoice --> access code --> review workflow. I understand the stack is locked to WordPress/PHP/MotoPress and will not propose Node, Laravel, or importing the Lovable mockup as code. Thanks, Hercules

Your setup is actually much more complex than a normal vacation-rental website because the difficult part here is the modular booking logic — multiple compatible reservation combinations, pricing rules, invoicing, and access automation all need to work together cleanly inside WordPress/MotoPress. Can help you build this completely on the locked stack: • WordPress + MotoPress architecture • custom PHP plugin for compatibility/incompatibility logic • seasonal pricing & modular booking flows • Stripe + IfthenPay integrations • InvoiceXpress automation workflow • Nuki smart-lock integration • multilingual Polylang setup • guest dashboard & self-service flows • transactional email automation • staging → production deployment workflow The important part will be structuring the custom plugin properly so business logic stays maintainable instead of scattering logic across theme files and plugin overrides. Let’s connect over chat/call and discuss: • compatibility matrix complexity • MotoPress customization boundaries • fiscal/payment flow expectations • staging/deployment architecture Can start immediately.

A Warm Hello! Your project is exactly the kind of advanced WordPress booking platform where custom PHP architecture matters far more than simple plugin setup. I have strong experience building custom reservation systems on WordPress, including complex availability logic, payment gateway integrations, multilingual setups, and API-driven automations. What stands out here is the modular accommodation logic with coexistence rules between configurations. I would implement this cleanly using MotoPress Hotel Booking as the core engine while extending it through a dedicated custom plugin for: Compatibility matrix & concurrent booking validation 30-day rental enforcement Seasonal pricing & discount rules Stripe + IfthenPay integration InvoiceXpress automation (ATCUD/QR compliant) Nuki API + Twilio automation Guest dashboard & self-service flows Transactional emails via Resend/Postmark I’m also comfortable working within Portuguese fiscal/payment ecosystems and understand the importance of stability, staging validation, and production-safe deployment. Proposed timeline: Reservation engine & multilingual setup – 2.5 weeks Payments, invoicing & guest flows – 3 weeks Smart lock, reviews, testing & deployment – 2 weeks Estimated timeline aligns well with your 7–8 week target. Let's set up a quick call to discuss things better. Let's discuss it more in chat. Best Regards, Jemin Sagar
