Outsourced Manufacturing Accounting Services

Manufacturing accounting is fundamentally different from service-based or retail accounting because of one factor: inventory. The conversion of raw materials into finished goods creates a complex cost flow that touches every part of the financial statements. Direct materials, direct labor, and manufacturing overhead must be tracked, allocated, and reported with precision to produce accurate cost of goods manufactured (COGM) and cost of goods sold (COGS) figures.

CPA firms serving manufacturing clients need specialists who understand job costing, process costing, standard costing, and activity-based costing (ABC) methodologies. Generic bookkeepers who post vendor invoices and reconcile bank statements cannot produce the cost variance analysis, WIP valuations, and inventory reports that manufacturing clients and their lenders require.

Job Costing and Work-in-Progress Tracking

Our manufacturing accounting specialists maintain job cost records that track direct materials, direct labor, and applied overhead for every production order. They calculate WIP valuations at month-end using the percentage-of-completion or units-of-production method depending on your client's operations, and they reconcile WIP sub-ledger balances against the general ledger control account.

For make-to-order manufacturers, this means accurate per-job profitability analysis that helps your clients identify which products and customers are truly profitable. For make-to-stock operations, we track standard costs against actual costs and calculate purchase price, labor rate, labor efficiency, and overhead volume variances.

Bill of Materials (BOM) and Variance Analysis

Maintaining accurate bills of materials is critical for cost accounting integrity. Your specialist works with the production team to ensure BOMs reflect current material specifications, labor routing times, and overhead allocation bases. When actual costs differ from standard costs, we calculate and report material price variances, material usage variances, labor rate variances, and labor efficiency variances so management can take corrective action.

Inventory Valuation and Management

Our team manages inventory valuation under FIFO, LIFO, weighted average, or specific identification methods per your client's accounting policy. We perform periodic inventory count reconciliation, adjust for obsolescence reserves, calculate lower of cost or net realizable value (LCNRV) adjustments, and produce the inventory disclosures required for audited financial statements.

For manufacturers with multiple warehouses or production facilities, we handle inter-facility transfers, in-transit inventory tracking, and consignment inventory accounting.
