Looking at the reconciliation data, I've identified **three critical blocks to sign-off**:

## 🚨 **Blocker 1: Account 2150 (Sales Tax Payable) — $68,820 Unexplained Difference**
- **GL Balance:** -$91,760.00
- **Subledger Balance:** -$22,940.00  
- **Difference:** -$68,820.00
- **Reconciling items:** 0 (nothing posted to explain this)
- **Impact:** This massive discrepancy is marked "Reviewed" but has zero reconciling items and no explanation. This requires immediate investigation — likely an accrual/remittance timing issue or posting error.

## 🚨 **Blocker 2: Account 1200 (Inventory) — Not Yet Reviewed**
- **Status:** "Prepared" (missing reviewer sign-off from Dana Whitfield)
- **Unexplained difference:** $1,240.55
- **Open item:** Cycle count variance of -$3,215.70 marked as "adjustment-needed" but not yet posted (RI-09, 9 days old)
- **Impact:** Cannot sign-off without reviewer approval and the pending cycle count variance needs to be posted.

## ⚠️ **Blocker 3: Account 1100 (AR) — Ancient Unidentified Item**
- **Unresolved item:** RI-05 - "Unapplied receipt, Lumen Retail, no remittance advice"
- **Amount:** -$14,260.00
- **Age:** 127 days old
- **Impact:** Even though reviewed, this old unapplied receipt with no supporting remittance advice is a red flag that needs investigation/resolution before sign-off.

**Recommendation:** Prioritize clarifying the Sales Tax Payable discrepancy (largest dollar impact), post the Inventory cycle count variance, have Dana review Account 1200, and trace the Lumen Retail receipt.
