Fiscal Year sets when your company’s accounting year begins, and how far back and how far ahead a person may date a manual journal entry or a vendor bill. Set it when you onboard, before you generate accounting periods, and review it when your accountant changes your fiscal calendar.

Before You Start

  • You need settings.edit. Roles without it do not see Fiscal Year in Settings, and opening the page from a link shows Access Restricted with a Back to Settings button.
  • Talk to your accountant before changing the fiscal year start on an entity that already has accounting periods.

Open Fiscal Year

  1. In the deck, open Settings.
  2. Under System, choose Fiscal Year.
The breadcrumb reads Settings > System > Fiscal Year. You can also search for Fiscal Year in the command palette.

Set The Fiscal Year Start

  1. Choose the Start month.
  2. Enter the Start day (1 to 28). The day stops at 28 so the year always starts on a day that exists in every month.
  3. Read the preview banner.
  4. Click Save fiscal year.
The default is January 1, a calendar year. The banner then reads that your fiscal year runs January 1 to December 31, with periods Jan through Dec and a fiscal-year wrapper for each year. For any other start, the banner names the current fiscal year and its dates, for example a year that starts July 1. A fiscal year is named by the calendar year in which it ends, so a year running July 1, 2026 to June 30, 2027 is FY 2027. New accounting periods follow this window: 12 monthly periods plus a fiscal-year wrapper.
Changing the fiscal year start only affects accounting periods generated from now on. Periods that already exist, closed periods, and posted journal entries are left exactly as they are. Generate new periods from Period Close, or wait for the monthly automatic set-up of periods.

Set The Backdate Window

The Journal entry backdating card has one box, Days a journal entry may be backdated. It controls how old the date of a manual journal entry or the effective date of a vendor bill may be. The default is 180 days, and you can enter any whole number from 0 to 3650. The text under the box repeats your number: a date more than that many days in the past is refused.
  • A manual journal entry or vendor bill dated further back than the window is refused.
  • A person holding accounting.close_period can still post one outside the window by giving a reason. The reason is recorded on the entry’s audit trail.
  • The override never reaches a closed period. A prior-period entry still has to land in a period that is open.

Set The Future Posting Window

The Future posting dates card has one box, Days ahead a posting date may be set. It controls how far after today the date of a manual journal entry or the effective date of a vendor bill may be. The default is 0, so a date after today is refused until you raise it. You can enter any whole number from 0 to 3650. When the window is more than zero, the text under the box says the date may be up to that many days after today, and that the entry posts to the general ledger on that date.
  • A date beyond the window is refused.
  • A person holding accounting.close_period can still post one by giving a reason. The reason is recorded on the entry’s audit trail, and the entry can only go into a monthly accounting period that exists and is open.
  • The window applies to the dates a person chooses on a manual journal entry or a vendor bill. Payments, receipts and automatic postings keep their own rules.
  • Days ahead and days behind are counted from the server’s day, the same day the server checks when it posts, so a different date on your own device does not change the guidance.
Click Save fiscal year to save. The start month and day, the backdate window and the future window all save together in one request.

Messages You May See

A validation message shows in a red notice above the button, and nothing is saved until it is fixed. Save fiscal year stays disabled until you change something, including when the only change is one of the two windows.

What Changes Elsewhere

  • Accounting periods: periods generated after the save follow the new fiscal year. Existing periods do not move.
  • Journal entries and vendor bills: both windows apply to every manual journal entry and every vendor bill effective date from the moment you save. An entry outside a window needs accounting.close_period and a reason.
  • Audit trail: saving the fiscal year start or either window is recorded in the Audit Log.
  • Other open sessions: when another admin saves this page, your page refreshes to show it.
