Production-grade playbooks for hotel PMS & channel manager rate parity automation.
Design, automate, and scale PMS/OTA synchronization, rate parity validation, inventory allocation, and revenue optimization.
Inventory Allocation is a working engineering library for the people who keep hotel distribution honest: revenue managers, hotel operations leads, and the Python automation engineers who build the pipelines behind them. It treats rate parity not as a manual spreadsheet drill but as a deterministic engineering problem — sub-second state synchronization, exactly-once processing, canonical schema contracts, and immutable audit trails.
Every page is a reference design for a real production workflow, grounded in concrete, runnable Python patterns, schema definitions, error-handling strategies, and observability hooks you can actually ship. No hand-waving, no stock diagrams — each guide walks from problem framing through architecture, runnable code, and the failure modes that bite in production.
- Revenue managers protecting ADR and RevPAR through enforced, monitored rate parity.
- Hotel operations leads who need physical and sellable room counts to stay identical across every channel.
- Python automation engineers building resilient PMS ↔ channel manager ↔ OTA integrations.
The library is organized into three areas, each a set of connected, in-depth guides:
Deterministic state sync, idempotent ingestion queues, a centralized pricing engine, parity circuit breakers, canonical schemas, OTA routing, security boundaries, overbooking prevention, compliance and audit logging, and PMS database optimization.
OAuth2 token lifecycles, webhook and polling ingestion, OTA rate-limit handling, error categorization and retry logic, dead-letter replay, batch reconciliation, and observability for sync pipelines.
Closing the parity loop: measuring OTA deviation, ingesting competitor benchmarks, driving a deterministic pricing rule engine, alerting on drift without alert fatigue, and tracking ADR/RevPAR KPIs.
A few of the reference designs practitioners open first:
- Rate Plan Taxonomy Design — canonical rate plan codes that survive PMS ↔ OTA mapping.
- Map Room Types Across Booking.com & Expedia — deterministic room-type mapping without parity drift.
- Building Batch Reconciliation Scripts for Daily Syncs — audit-grade nightly reconciliation with checksum validation.
- Parity Monitoring & Alerting — score OTA deviation and page only on sustained, real drift.
- Runnable Python — Pydantic v2 contracts, Polars for batch work,
httpx/tenacitytransport, andstructlogstructured logging, using realistic hospitality identifiers throughout. - Hand-authored diagrams — every architecture, data-flow, and state diagram is an original inline SVG that adapts to light and dark themes.
- Structured data — every page ships valid JSON-LD (Article, Breadcrumb, HowTo, FAQ) for rich search results.
- Fast and accessible — a static, offline-capable progressive web app that meets WCAG 2 AA.
- Eleventy static site generator (Nunjucks + Markdown)
- Prism syntax highlighting, hand-authored inline SVG diagrams
- Progressive web app (service worker, offline page, web manifest)
- Deployed on Cloudflare Pages
