Reconcile accounts by comparing GL balances to subledgers, bank statements, or third-party data. Use when performing bank reconciliations, GL-to-subledger recs, intercompany reconciliations, or identifying and categorizing reconciling items.

Methodology and best practices for account reconciliation, including GL-to-subledger, bank reconciliations, and intercompany. Covers reconciling item categorization, aging analysis, and escalation.
Compare the general ledger control account balance to the detailed subledger balance.
Common accounts:

Common causes of differences:
Compare the GL cash balance to the bank statement balance.
Process:
Standard format:
Balance per bank statement: $XX,XXX
Add: Deposits in transit $X,XXX
Less: Outstanding checks ($X,XXX)
Add/Less: Bank errors $X,XXX
Adjusted bank balance: $XX,XXX
Balance per general ledger: $XX,XXX
Add: Interest/credits not recorded $X,XXX
Less: Bank fees not recorded ($X,XXX)
Add/Less: GL errors $X,XXX
Adjusted GL balance: $XX,XXX
Difference: $0.00
Reconcile balances between related entities to ensure they net to zero on consolidation.

Common causes of differences:
Items that exist because of normal processing timing and will clear without action:
Expected resolution: These items should clear within the normal processing cycle (typically 1-5 business days). No adjusting entry needed.
Items that require a journal entry to correct:
Action: Prepare adjusting journal entry to correct the GL or subledger.
Items that cannot be immediately explained:
Action: Investigate root cause, document findings, escalate if unresolved.
Track the age of reconciling items to identify stale items requiring escalation:
| Age Bucket | Status | Action | |-----------|--------|--------| | 0-30 days | Current | Monitor — within normal processing cycle | | 31-60 days | Aging | Investigate — follow up on why item has not cleared | | 61-90 days | Overdue | Escalate — notify supervisor, document investigation | | 90+ days | Stale | Escalate to management — potential write-off or adjustment needed |
| Item # | Description | Amount | Date Originated | Age (Days) | Category | Status | Owner | |--------|-------------|--------|-----------------|------------|----------|--------|-------| | 1 | [Detail] | $X,XXX | [Date] | XX | [Type] | [Status] | [Name] |
Track reconciling item totals over time to identify growing balances:
Define escalation triggers based on your organization's risk tolerance:
| Trigger | Threshold (Example) | Escalation | |---------|---------------------|------------| | Individual item amount | > $10,000 | Supervisor review | | Individual item amount | > $50,000 | Controller review | | Total reconciling items | > $100,000 | Controller review | | Item age | > 60 days | Supervisor follow-up | | Item age | > 90 days | Controller / management review | | Unreconciled difference | Any amount | Cannot close — must resolve or document | | Growing trend | 3+ consecutive periods | Process improvement investigation |
Note: Set thresholds based on your organization's materiality level and risk appetite. The examples above are illustrative.
development
Use this skill any time a spreadsheet file is the primary input or output. This means any task where the user wants to: open, read, edit, or fix an existing .xlsx, .xlsm, .csv, or .tsv file (e.g., adding columns, computing formulas, formatting, charting, cleaning messy data); create a new spreadsheet from scratch or from other data sources; or convert between tabular file formats. Trigger especially when the user references a spreadsheet file by name or path — even casually (like "the xlsx in my downloads") — and wants something done to it or produced from it. Also trigger for cleaning or restructuring messy tabular data files (malformed rows, misplaced headers, junk data) into proper spreadsheets. The deliverable must be a spreadsheet file. Do NOT trigger when the primary deliverable is a Word document, HTML report, standalone Python script, database pipeline, or Google Sheets API integration, even if tabular data is involved.
content-media
Interactive PDF viewer. Use when the user wants to open, show, or view a PDF and collaborate on it visually — annotate, highlight, stamp, fill form fields, place signature/initials, or review markup together. Not for summarization or text extraction (use native Read instead).
documentation
Write or review UX copy — microcopy, error messages, empty states, CTAs. Trigger with "write copy for", "what should this button say?", "review this error message", or when naming a CTA, wording a confirmation dialog, filling an empty state, or writing onboarding text.
development
Rapidly triage an incoming NDA and classify it as GREEN (standard approval), YELLOW (counsel review), or RED (full legal review). Use when a new NDA arrives from sales or business development, when screening for embedded non-solicits, non-competes, or missing carveouts, or when deciding whether an NDA can be signed under standard delegation.
