A financial period is a defined window of time — a month, a quarter, or a year — during which your organization records transactions and measures its financial performance. Think of each period as a sealed chapter in your financial history: while it is open, you can write in it freely; once it is closed, the record becomes permanent and tamper-proof. Managing periods well is one of the most important habits you can build as a tontine administrator, because it is what transforms a pile of transaction records into a reliable, auditable financial history.

​
The Three Period Types

When your organization is set up in Agatabo, an administrator configures one period type that applies to all your accounting cycles. Choose based on how active your group is and how much administrative capacity you have.
Closes: At the end of every calendar month (12 closings per year)Monthly periods give you the most frequent financial snapshots and the fastest feedback loop for spotting errors or emerging problems.Pros:
  • Errors are caught quickly — within weeks, not months
  • Members receive up-to-date statements more frequently
  • Easier to reconcile smaller volumes of transactions
  • Generates a rich set of period-over-period comparison data
Cons:
  • Requires consistent administrative effort every month
  • More closing procedures to complete annually
Best for: Active tontines with frequent loan disbursements, regular contributions, and medium-to-large membership (20+ members).
Aim to close your monthly period within 5–10 days of month-end while transactions are fresh. Waiting until day 20 makes reconciliation harder and increases the risk of missing entries.

​
Period Status

At any moment, each financial period in Agatabo has one of two statuses:
StatusWhat It MeansCan You Edit Transactions?
OpenThe current active period — transactions are being recorded✅ Yes
ClosedA locked historical period — the record is permanent❌ No
Only one period is Open at a time. When you close the current period, it becomes Closed and the next period automatically opens. Transactions are always recorded in the Open period; you cannot post a new transaction into a Closed period.

​
Why Closing Periods Matters

Closing a period is not just an administrative formality. It serves three essential purposes:
  1. Data integrity — Once a period is closed, no one can alter, delete, or backdate its transactions. This protects your financial history from accidental changes and deliberate fraud.
  2. Audit trail — A series of closed periods creates an immutable, time-stamped record. Auditors, board members, and regulators can trust that what they see is exactly what happened.
  3. Clean reporting — Closing a period posts the automated entries that reset revenue and expense accounts, carry net income into retained earnings, and prepare your chart of accounts for the next cycle.
Closing a period is permanent. Once you close a period in Agatabo, all its transactions become read-only and the closing journal entries are posted automatically. You cannot undo a close — you can only reopen the most recent closed period in exceptional circumstances. Complete all corrections, reconciliations, and report exports before you close.

​
What Happens When a Period Closes

When you trigger a period close, Agatabo performs the following steps automatically:
  1. All transactions in the period become read-only. No further edits, deletions, or additions are possible.
  2. Closing journal entries are posted. Revenue and expense account balances are transferred to retained earnings.
  3. The period status changes to Closed.
  4. The next period opens and becomes the new active period for recording transactions.
Example — Closing December 2025: 
Before closing:
  December Revenue:   500,000 RWF
  December Expenses:  300,000 RWF
  Net Income:         200,000 RWF

Automated closing entries:
  Debit  Revenue          500,000   (zeroes out revenue for new period)
  Credit Expenses         300,000   (zeroes out expenses for new period)
  Credit Retained Earnings 200,000  (net income transferred)

After closing:
  Revenue account:          0 RWF  (fresh start for January 2026)
  Expenses account:         0 RWF  (fresh start for January 2026)
  Retained Earnings:  +200,000 RWF (permanently recorded)
Your Balance Sheet immediately reflects the updated retained earnings, and your Profit & Loss for January starts clean at zero.

​
Pre-Close Checklist

Run through these steps before closing any period. Completing them in order prevents the most common closing errors.
1

Record All Transactions

Confirm that every contribution, loan disbursement, repayment, fee, and expense for the period has been entered in Agatabo. Check with your loan officer and treasurer for any pending items.
2

Reconcile Bank Accounts

Compare Agatabo’s cash balance against your actual bank statement. Investigate and resolve every difference before proceeding. An unreconciled bank account is the most common source of post-close corrections.
3

Verify Trial Balance

Run the Trial Balance report in Agatabo. Total debits must equal total credits. If they do not, there is an error to find and fix before you close.
4

Generate and Save Financial Reports

Export your Balance Sheet and Profit & Loss statement for the period. Save them to your organization’s archives (cloud storage, email, or printed copy). Once the period closes, these figures are locked — make sure you have your copies.
5

Clear Pending Corrections

If you know of any errors or adjustments to make, do it now. After closing, you cannot edit historical transactions — any corrections must be made as adjustment entries in the next open period.

​
Reopening a Closed Period

In rare cases, you may need to reopen the most recently closed period to correct a significant error. When reopening is appropriate:
  • A materially significant transaction was missed and cannot be adequately corrected in the current period
  • A regulatory requirement mandates a correction to the closed period’s records
  • An audit finding requires restating a prior-period figure
When to use an adjustment entry instead:
  • The error is minor and does not materially misstate any financial statement
  • You want to avoid the administrative overhead of a full re-close
  • The correction is a routine reclassification between accounts
Agatabo only allows reopening the most recently closed period. Older periods are permanently locked to prevent historical manipulation. This restriction is intentional and cannot be overridden.
How to reopen:
  1. Navigate to Advanced → Period Closing → Reopen Period
  2. Document the reason for reopening (required — this note becomes part of your audit trail)
  3. Make your corrections
  4. Re-run the pre-close checklist above
  5. Close the period again immediately — do not leave a prior period open while the current period is also active
Reopening should be a rare exception, not a routine practice. If you find yourself reopening periods frequently, it is a sign that your closing process needs improvement — not that reopening is the right solution.

​
Comparative Period Reporting

Once you have several closed periods, Agatabo can generate comparative reports that show multiple periods side by side — one of the most powerful tools for spotting trends and making informed decisions. Monthly comparison example:
ItemApril 2026May 2026June 2026
Total Revenue420,000450,000500,000
Total Expenses260,000280,000300,000
Net Income160,000170,000200,000
Year-over-year example:
Item20252026Growth
Total Member Savings10,000,00012,000,000+20.0%
Loans Outstanding8,000,00011,000,000+37.5%
Net Income800,000950,000+18.8%
Use these comparisons to identify seasonality in contributions, track the growth of your loan portfolio, and present clear performance narratives at board meetings.
