A hotel extranet lets travel companies and hotels manage contracted rooms, rates and availability, and sell them through booking channels. Building one, or customising an existing product, involves decisions that shape how well it works for years. This article walks through the development steps and the key choices to make early.
1. Define the users
- Contracting team: loads contracts, rates and restrictions.
- Hotels: may log in to update availability, stop-sells and confirm bookings.
- Sales channels: B2C website, B2B agents and API partners who search and book.
- Finance: needs payables and margin reports.
Each group needs its own screens and permissions.
2. Choose the rate and contract model
Decide how rates will be stored: per room or per person, by season, meal plan and occupancy, with child policies, supplements and offers. This is the most important design decision, because every search depends on it. Getting it wrong leads to wrong prices or endless workarounds.
3. Design availability logic
- Allotments by room type and date.
- Release periods and free-sale rules.
- Stop-sells, minimum stays and closed-to-arrival dates.
- On-request booking when allotment runs out.
4. Build booking flows
- Instant confirmation within allotment.
- On-request bookings that hotels confirm or decline.
- Notifications to hotels by email or in their login.
- Cancellations with penalties based on contract terms.
- Vouchers for guests with hotel confirmation numbers.
5. Hotel logins (optional but valuable)
Giving hotels their own login to update availability and stop-sells reduces delays and errors. Keep their view simple: their property, rooms, dates and bookings.
6. Integrations
- Your booking engine, so extranet hotels appear next to supplier API hotels.
- Hotel mapping, so a hotel from your extranet and a bedbank appears once.
- APIs for partners who want to sell your contracted inventory.
- Optional channel manager connections for hotels that use them.
7. Reports
- Bookings and room nights by hotel and season.
- Allotment usage and released rooms.
- Revenue, cost and margin.
- Hotel payables.
8. Testing
Test real contracts: overlapping seasons, child policies, festive supplements, early-bird offers and long-stay discounts. Compare extranet prices with manual calculations for typical bookings before launch.
Build or buy?
Ready extranet products launch faster and cover common contract models. Custom development makes sense when your contracts or distribution model are unusual. Many companies customise an existing extranet rather than building from scratch.
In practice: starting with the rate model
A DMC's first extranet attempt stored only a single price per room per night. It could not handle child policies or meal plan supplements, so staff calculated many quotes by hand. The second version started with a rate model designed around real contracts, and almost every booking was then priced automatically.
Common mistakes
- Designing screens before agreeing the rate model.
- Leaving hotel logins and stop-sell handling for later.
- No mapping between extranet hotels and supplier hotels, causing duplicates.
Frequently asked questions
How long does extranet development take?
It depends on contract complexity and integrations; customising an existing product is usually much faster than a new build.
Can extranet rates be sold to other agencies?
Yes, through a B2B portal or an outbound API.
Key takeaways
- Design the rate and availability model around real contracts first.
- Give each user group, including hotels, the right tools.
- Integrate with your booking engine and mapping so inventory sells everywhere.
