What it is
Every póliza (journal entry) has a number and a date. The number is a sequence that restarts at 1 every month. The date decides the period: the accounting month the póliza counts in.
How numbering works
- One sequence per month for every póliza: daily ones, manual ones, those created by supplier invoices, payments, payroll, depreciation and banking, and the year-end closing póliza.
- The number follows the order in which pólizas are recorded, not the date they carry. A manual póliza dated the 3rd and captured on the 20th gets the next free number of the month.
- A canceled póliza keeps its number: nothing is deleted, so no number is ever reused.
- If your hotel runs several properties in the same set of books, there is one sequence for all of them, and a single property's list may skip numbers.
The date each póliza carries
| Póliza | Date it carries |
|---|---|
| Daily | The business date, even if the day is signed the next morning. |
| Manual | The one you choose when you capture it. |
| Supplier invoice | Its issue date. |
| Supplier payment or payroll payment | The payment date. |
| Payroll record | The accounting date you give it when you record it. |
| Depreciation | The last day of the month being depreciated. |
| Bank movement recorded as an expense | The movement date. |
| Year-end close | December 31. |
The period
The accounting period is the month. While it is open it takes pólizas; once it is closed in Cierre de mes (month close), no new póliza dated in that month gets in: not the daily one, not a manual one, not those from other modules. The only exception is the year-end closing póliza, recorded on December 31 even if December is already closed (year-end close).
Step by step
- Open Containn → Pólizas.
- Type the month in the Mes (month) field as year-month: 2026-09.
- The list is sorted by date and, within each date, by number. The Póliza column shows the number with a # sign.
What can go wrong
- A day signed in a month that is already closed ends up without a póliza. The month close checks signed days, not that every day is signed. Close the month once all its days are signed (month-end close).
- A missing number is not a deleted póliza. In a hotel with several properties, it belongs to another property in the same books.
