Who this is for

Built for spreadsheet-heavy reconciliation

Bank feed exports against ledgers

Open invoices against payment reports

Client-ready exception lists

Manual workflow in Excel

What teams do manually today

Most teams start by exporting two files, adding helper columns, and using lookup formulas to find missing rows.

Recurring work often becomes a workbook that only one preparer fully understands.

Reviewers need matched and unmatched outputs, not just highlighted cells.

Where manual reconciliation breaks

The common failure points

Manual formulas break when source headers change, keys repeat, or date and amount formats drift.

Grouped payouts, partial payments, refunds, and timing items are difficult to explain with one lookup column.

Audit handoff becomes slower when match logic lives across hidden tabs.

How FireLookup handles it

A cleaner reconciliation workflow

FireLookup gives teams a guided two-file reconciliation workflow.

Exact, fuzzy, one-to-many, and many-to-many matching help with real operational file patterns.

Matched and unmatched exports make review and follow-up easier.
