Get Custom Hotel AI Without Hiring a Full-Time Engineer
Small hotels should hire a specialized AI agency to build production-grade automation. Building in-house requires a full-time engineer, which most properties cannot afford. The challenge is integrating AI with a Property Management System (PMS), payment gateway, and smart lock system, beyond just a simple chatbot. A production system needs to manage real-time room inventory checks, booking modifications, and guest communication across SMS and voice reliably. The scope of an AI automation project for a hotel depends on the desired automations, complexity of PMS integration, and the number of communication channels to support.
Syntora offers specialized AI automation services for small hotels, focusing on integrating AI with existing Property Management Systems (PMS), payment gateways, and smart lock systems. This approach allows hotels to automate guest communication and check-in processes efficiently without requiring in-house AI engineering teams.
What Problem Does This Solve?
Most hotels first try off-the-shelf chatbot builders. These tools are great for answering static questions like "What time is checkout?" but they cannot access real-time hotel data. When a guest asks "Do you have a king room available for tonight?", the bot can only respond with "Please call our front desk," because it has no connection to the live inventory in your PMS.
A more technical owner might try to connect systems using integration platforms. This approach is brittle. A workflow to handle a new booking might need to read from your PMS, create a charge in Stripe, and send an SMS confirmation via Twilio. If the PMS API is slow to respond, the entire workflow times out, leaving the guest without confirmation and your staff unaware of the failure.
We saw this with a 20-room inn that tried to build a self-check-in process. A web form would email the manager, who then had to manually create a smart lock code and email it to the guest. This manual process frequently broke on weekends, with guests waiting outside for 30 minutes to get into their room.
How Would Syntora Approach This?
Syntora would begin by connecting directly to your PMS API, whether it is Mews, Cloudbeds, or another platform, using their documented REST or GraphQL endpoints. Syntora would map your guest communication workflows, from initial booking inquiry to post-checkout follow-up. This would allow for building logic that reflects your property's specific policies and room types.
For voice AI, a FastAPI application would manage incoming calls through Twilio. The Claude API would be used for natural language understanding to interpret caller intent, such as 'modify a booking' or 'request an early check-in'. We have experience building document processing pipelines using the Claude API for financial documents, and the same pattern applies to interpreting guest requests. Core Python logic would execute real-time availability checks against the PMS for every query.
For check-in automation, the system would query the PMS 24 hours before a guest's arrival, verify payment, and generate unique door codes using the smart lock's API (e.g., Schlage or Salto). That code would be scheduled for delivery to the guest via a Twilio SMS an hour before check-in time. All interaction data, including call transcripts and SMS logs, would be stored in a Supabase database for auditing.
The system would be deployed as serverless functions on AWS Lambda to manage hosting costs. Syntora would implement structured logging with `structlog` and configure alerts in Slack for any API failures or high-latency events, allowing for issues to be addressed.
What Are the Key Benefits?
Live in 4 Weeks, Not 6 Months
A full production system from discovery to deployment in one month. Your front desk staff sees an immediate reduction in repetitive tasks.
No Per-Agent SaaS Fees
You pay for the one-time build and a flat, low-cost monthly hosting fee on AWS. The price does not increase with call volume or staff size.
You Own the Code and Infrastructure
We deliver the complete Python source code in your GitHub repository and transfer ownership of the AWS account. You have zero vendor lock-in.
Real-Time Failure Alerts in Slack
If your PMS API goes down or a payment fails, we get an immediate Slack notification. We build runbooks to handle common errors.
Direct PMS and Smart Lock Integration
We connect directly to Mews, Cloudbeds, Schlage, and Salto APIs. The system reads and writes data to your core hotel software.
What Does the Process Look Like?
Week 1: System and Workflow Audit
You provide read-only API keys for your PMS and other systems. We document your current call handling and guest check-in processes and deliver a technical specification.
Week 2: Core Logic and API Build
We build the core FastAPI service that connects your systems. You receive a private API endpoint to test basic functions, like checking room availability.
Week 3: Voice and Chat Interface Deployment
We connect the backend to Twilio for voice and SMS. You receive a dedicated phone number to test the live voice agent and interact with it.
Week 4+: Launch, Monitoring, and Handoff
We go live and monitor system performance for 30 days. You receive the full source code, deployment scripts, and a detailed runbook for ongoing maintenance.
Frequently Asked Questions
- How much does a custom hotel AI system cost?
- Cost depends on the number of systems to integrate (PMS, smart locks, channel manager) and workflow complexity. A voice agent for a hotel with one PMS is typically a 4-week project. Adding automated check-in with a smart lock system adds another week of development. Book a discovery call at cal.com/syntora/discover for a detailed scope and quote.
- What happens if the AI gives a guest wrong information?
- The system is designed to fail safely. If the AI is less than 95% confident in its answer to a booking query, it automatically transfers the call to the front desk. For every interaction, a full transcript and the AI's reasoning are logged in a Supabase database, so we can audit any errors and retrain the system immediately.
- How is this different from a PMS with a built-in chatbot?
- Built-in PMS chatbots, like the one in Mews, handle simple FAQs. They cannot execute complex actions like modifying a booking or coordinating with external systems, such as telling a smart lock to generate a new key. A custom build orchestrates actions across all your hotel's software, not just the features within the PMS.
- Does this work with our existing phone number?
- Yes. We can port your existing front desk number to Twilio, which will route calls to the AI agent first. If a human is needed, the call is forwarded to your existing phone line or a mobile number. There is no change for your guests, and you maintain complete control and ownership of your phone number.
- Can the AI agent handle multiple languages?
- Yes, the Claude API we use supports multiple languages, including Spanish, French, and German. We can configure the voice agent to detect the caller's language and respond appropriately. This is scoped during the initial audit to ensure we use the correct voice fonts and translated responses for your property's specific needs.
- What ongoing maintenance is required after launch?
- The system runs on AWS Lambda, which is serverless, so there are no servers to manage. The primary task is monitoring for API changes from your PMS provider. If your provider releases a major breaking update, a few hours of developer time may be needed to adapt. We offer an optional monthly support plan to cover these updates.
