Most hospitality businesses run on a collection of disconnected tools — a booking system, a point-of-sale system, one or more spreadsheets, a customer communication platform, and accounting software like Fortnox. Each system captures part of reality, but none holds the complete picture. A single relational data model connects them, so operations and accounting finally describe the same events.
What a relational data model actually means
A relational data model for operations treats reservations, orders, invoices, and customer interactions as connected entities. Instead of asking “which system owns this information,” the question becomes “how does this information relate to everything else.”
Here’s what that looks like in practice:
- A reservation links to a customer profile, a specific date and time, and one or more locations
- Orders placed on site attach to that reservation and customer
- Payments and invoices connect back to reservations and orders
- Accounting entries mirror these relationships, instead of existing as isolated lines
How staff use it day to day
Tools like Softr and TapeApp expose this structure to staff through custom interfaces. A staff member can search for a reservation and immediately see the related orders, payments, and notes — regardless of which underlying system stores each piece of data.
Fortnox and Pleo remain the financial backbone. The integration strategy respects the relational model, so every accounting entry has a clear origin in operations rather than sitting as an isolated line.
The result
Less manual work, fewer misunderstandings, and a foundation that’s easier to extend with new services later.
