Case study · Hotel construction

A hotel under construction,
every purchase tied to its budget.

A new hotel is being built. ARMKU set up the system that controls the money going out during construction: purchase orders, supplier bills and payments, each one tagged to its chapter of the project budget; a report that shows management where every chapter stands; and a step-by-step manual so the team runs it on its own.

Nothing bought outside the budgetEach purchase line lands in its budget chapter automatically.
One report for managementBudget, committed, billed and remaining, chapter by chapter.

How the money moves

From the quote request to the budget.

1

Request

The quote request goes to the supplier as a PDF.

2

Order

The confirmed order counts as committed in its chapter.

3

Advance

Advance payments are recorded before the bill arrives.

4

Bill

The supplier bill is created from the order and counts as billed.

5

Pay

Full or partial payments, and what is still owed to each supplier.

6

Control

The report shows every chapter against its budget.

What we built

Six pieces, one system.

Delivered: built, loaded with the client's own data and handed over to the team together with its manual.

01

The manager's report: budget control

Delivered
  • For each chapter: budget, committed in open orders, billed, remaining and percent consumed.
  • It reads the same orders and bills the team already enters: no spreadsheet on the side.
  • An in-house module, because the free edition of Odoo 18 has no budget app.
02

Purchasing and payments

Delivered
  • Quote requests, purchase orders, supplier bills and payments, full or partial.
  • Advance payments to suppliers, recorded before the bill.
  • What is owed to each supplier, always up to date.
03

Every line tagged to its chapter

Delivered
  • Eight chapters: site work, substructure, structure and facade, interiors, furniture and equipment, building services, bonds and insurance, and contingency.
  • Fifteen rules read the product category and fill in the chapter: nobody has to remember a code.
  • Budget figures loaded from the project's own work breakdown.
04

The project's data, from its own files

Delivered
  • 142 products and 62 suppliers, read straight from the client's spreadsheets.
  • 21 categories that separate construction work from furniture, fixtures and equipment.
  • A loader that can run again safely whenever the spreadsheets change.
05

Local taxes, set up in-house

Delivered
  • Odoo ships no tax package for that country, so we built it: sales tax, an exempt rate and two withholdings, each with its own account.
  • Every product picked up the right tax automatically.
06

The manual: a step-by-step guide

Delivered
  • Twelve sections and two annexes: request, order, advance, bill, pay and control the budget.
  • Written for the people who enter the purchases, not for programmers.
  • Delivered as a branded PDF together with the system.
  • The whole system in Spanish, screens and menus included.

What comes next

Electronic invoicing when the project has to issue its own tax documents, and hotel operations, from reservations to rates, when the building opens. Same system, new modules.

How we built it

The client's files first, then the software.

Their spreadsheets became the data

The budget, the furniture lists and the finishes schedule are inside the system, not in a parallel file.

Open-source Odoo, no license per user

What the free edition lacked, like the budget report, we built.

Loads that can run twice

Every data load and tax setup is a script that can run again without duplicating anything.

In the team's language

Screens, menus and the manual in Spanish, written for daily use.
