How do I know which of the seven breaks is causing my invoice–GL gap?

Follow the 90-minute checklist: check tax and rounding first (15–30 mins), then GL account allocation (31–50 mins), then timing and duplicates (51–70 mins), then refunds and reversals (71–85 mins). The variance amount often hints at the culprit—a ₹5K gap that's exactly 5% suggests a tax recalculation; one that's ₹0.49 suggests rounding; one that's exactly ₹5,000.00 suggests a refund or duplicate that posted separately.

Can I fix a historical invoice–GL mismatch without re-closing the month?

Yes, but carefully. If the variance is under 1% and clearly documented (e.g., a rounding error), many auditors allow a one-time adjustment entry posted to a "prior-period adjustment" account. If it's larger or the cause is unclear, you may need to reopen the period, fix the GL entry or the invoice, and re-close. Check your company's financial close policy and your auditor's guidance first.

What if my billing platform and GL use different tax rates for the same product?

This is a configuration mismatch. Audit both systems' tax settings for that product. One is wrong, or they're designed to use different rates intentionally (e.g., billing applies inclusive tax, GL applies exclusive). Decide which is correct for your business and your jurisdiction, then align the other system to match. If both are intentional, document it and adjust for it in your reconciliation process every month.

Should I sync invoices to GL on creation or on payment?

On creation. Syncing on payment introduces timing gaps (as described in break #4) and can cause invoices to post in the wrong accounting period. Revenue recognition principles require recording revenue when earned, not when paid. Configure your sync to post on invoice creation, regardless of payment status. If your GL requires a "paid" indicator, post that as a separate field, not as a gating condition for the main invoice entry.
