Understanding Fiscal Periods

A fiscal year is a 12-month accounting period used for financial reporting. Bamboo tracks fiscal years and manages the period closing process to ensure your financial data is accurate and compliant.

Your fiscal year determines:

  • When your accounting year starts (e.g., January 1, April 1, July 1)
  • When financial statements are prepared (at year-end)
  • How income and expenses are grouped for reporting

In Bamboo, each fiscal year goes through three stages:

StatusDescriptionCan Post Entries?Can Reverse Close?
OpenCurrent working period✅ Yes
ClosedFinalized, in grace period⚠️ Yes (with warning)✅ Yes
LockedPermanently sealed❌ No❌ No

The lifecycle flows like this:

Open(you close the period)Closed(grace period expires)Locked

Bamboo automatically determines your current fiscal year based on:

  1. Your organization’s fiscal year start month (set during onboarding)
  2. Today’s date

Examples (assuming today is March 15, 2026):

  • January start: Your fiscal year is FY 2026 (January 1, 2026 – December 31, 2026)
  • July start: Your fiscal year is FY 2025-2026 (July 1, 2025 – June 30, 2026)

When your fiscal year ends, you’ll close the period which:

  1. Calculates net income (Revenue − Expenses)
  2. Creates a closing journal entry that transfers net income to Retained Earnings
  3. Resets income and expense accounts to zero for the new year
  4. Starts a grace period for any corrections

After closing, you have a configurable grace period (default: 14 days) to make corrections if needed.

During the grace period:

  • You can reverse the close with a reason
  • Reports show the period as “Closed”
  • Entries to the closed FY can still be posted (with a warning)
  • Entries to the new FY post normally without warning

After the grace period expires, the period is automatically locked and no entries can be posted.

Navigate to Reports → Period Close to:

  • View your current fiscal period status
  • See days remaining until year-end
  • Preview the closing entry (revenue, expenses, net income)
  • Close the period when ready
  • Reverse a closed period (during grace period)
  • View history of closed periods

Bamboo shows contextual banners based on your organization’s period close settings:

  1. Prepare early

    Start your year-end checklist 2-4 weeks before the fiscal year ends.

  2. Reconcile all accounts

    Ensure bank accounts, receivables, and payables are accurate.

  3. Review the closing preview

    Check that revenue and expenses look correct before closing.

  4. Close promptly

    Close within the first week of the new fiscal year.

  5. Document any reversals

    If you need to reverse a close, provide a clear reason for the audit trail.
