Cost number

What is the cost number?

This number is intended for internal use only within your records. It helps Gekko uniquely identify and neatly organize your costs.

Can I change the number?

Although the field is editable, we strongly advise against changing it. The system manages the numbering automatically in the most efficient way.

What should I look out for if I change it anyway?

If you do decide to enter a number manually, please keep the following two points in mind:

• Avoid duplicate numbers: A cost number must be unique. If you use a number that already exists in your records, Gekko will not be able to save the expense.
  
  
• Cost Number vs. Invoice Number: Do not confuse the cost number with the invoice number of the receipt you are trying to upload. The invoice number is the number provided by your supplier; the cost number is your own internal reference number.

Our recommendation: The [YEAR]-000001 standard

We recommend using Gekko's standard notation: 2026-000001, 2026-000002, etc.

The main advantage is that the numbering automatically updates with the new year, keeping your administration organized and consistent over time.
