Corrections
Correct a posted document without rewriting the month
When a posted document turns out to be wrong, most systems offer three exits: reopen a signed month, delete the evidence, or post a manual journal that leaves stock and cost wrong underneath. Cairn gives a posted document two plain verbs, Delete and Reverse, and keeps the trail either way.

How Cairn closes the gap
The legacy gap
Reopening a closed month restates figures the owner, the lender and the auditor have already seen. Deleting rewrites history. A manual journal fixes the ledger while the shipment, the lot and the cost layers still say the goods left.
What Cairn does
Delete, in an open period only, unwinds a document and its postings and replays what came after. Reverse keeps the original on file with a Reversed badge and posts a mirror document (REV-n), dated today in the current open period and linked both ways. Stock goes back at the cost that left, and nothing in between is re-costed.
The payoff
October stays as it was signed. The correction is a visible, dated event in November, and an auditor reaches the original and its mirror from either record in one click.
The documents it keeps
Every step is a numbered record you can open, link and audit, not a note in an inbox.
REV-n
Reversal
The mirror of a posted document, dated today, linked both ways.
ICR-n
Inventory cost revaluation
A change of costing method or standard, posted as its own document.
What it does
Two verbs, one habit
Receipts, shipments, returns, credit memos, vendor returns, adjustments, builds, work-order completions, material issues and counter sales, plus invoices, bills, payments, deposits and journal entries.
The cost that left comes back
The mirror returns stock at the sale's own consumed cost, never today's cost, so a correction cannot manufacture margin out of an error.
Closed months stay closed
The mirror is dated in the current open period. Nothing after the original is re-costed, so figures people have already used do not move.
Cost of Sales Adjustment, only where it belongs
A third leg appears only for a standard-cost item whose standard moved since the original, and it sits on its own line where the controller can see it.
A change of basis is a document
A change of costing method or standard posts as an inventory cost revaluation (ICR-n) with its own postings, never as a quiet edit to the item.
Two presses, no clock
Delete and Reverse each ask for a second press before anything posts, and a refusal names the later document that must be corrected first.
