How to close the books for a manufacturer
A problem-to-playbook guide to the manufacturing close - from inventory reconciliation to a COGM schedule - so your cost of goods sold is right, not a plug.
Why a manufacturing close is different
A manufacturer’s close lives or dies on inventory. Raw materials, WIP, and finished goods all have to be right before cost of goods sold means anything, and the E&O reserve has to be trued up so inventory isn’t overstated. Skip those and COGS becomes a balancing figure instead of a computed one.
- Inventory movements must be posted and valued by the costing method.
- Open work orders carry WIP that has to be understood at period end.
- The E&O reserve is a close task, not an annual one.
The manufacturing close, in order
Five manufacturing-specific steps
- 1
Reconcile inventory
Confirm receipts, issues, and adjustments (including cycle counts) are posted and valued correctly per item.
- 2
Complete and review work orders
Complete finished work orders so WIP relieves to finished goods; review WIP still open at period end.
- 3
True up the E&O reserve
Recalculate the reserve and post the delta so inventory is carried at net realizable value.
- 4
Review variances
Read the variance report and understand material, labor, and overhead variances for the period.
- 5
Build COGM and COGS
Produce the cost-of-goods-manufactured schedule and the resulting cost of goods sold.
Controls that make the close reliable
A stock ledger with a running quantity, dedicated variance and reserve accounts, and journal entries for every cost-flow step mean the close is a review of real postings, not a reconstruction. Every inventory and COGS number traces back to a transaction.
How Fintra runs the close
Fintra posts every cost-flow step to the GL, keeps an auditable stock ledger, trues up the E&O reserve on a delta basis, and builds the COGM and COGS schedules from real work-order postings - with AI proposing and a person approving. The result is a manufacturing close that reconciles, month after month.
Frequently asked questions
What’s different about a manufacturing month-end close?
It centers on inventory: raw materials, WIP, and finished goods must be reconciled and valued before cost of goods sold is meaningful, and the excess-and-obsolete reserve must be trued up. Only then do the cost-of-goods-manufactured and cost-of-goods-sold schedules reconcile.
What order should I close a manufacturing period in?
Reconcile inventory movements, complete and review work orders so WIP relieves to finished goods, true up the E&O reserve, review variances, then build the COGM and COGS schedules. Doing inventory first ensures the downstream cost schedules are based on correct balances.
How does WIP affect the manufacturing close?
Open work orders hold WIP that hasn’t relieved to finished goods. Because cost of goods sold depends on the change in WIP and finished goods, understanding period-end WIP is essential - completing finished work orders and reviewing what remains open keeps COGS accurate.
Can Fintra automate the manufacturing close?
Yes. Fintra posts each cost-flow step to the ledger, maintains an auditable stock ledger, trues up the E&O reserve on a delta basis, and builds the COGM and COGS schedules from real postings - with AI drafting and a person approving each entry, so the close is repeatable.
