Manufacturing Accounting know every product's cost.
For small and mid-sized manufacturers who want clear product costs, inventory they can trust, and margins they can explain to a lender or a partner.
Manufacturing accounting is where operations and finance meet. Material prices move, labor and machine time shift between products, scrap and yield vary by run, and overhead has to land somewhere. When the books treat all of it as one line called cost of goods sold, you lose the view you need to price a quote, buy equipment, or add a shift. TreeStar brings bookkeeping, payroll, tax, and advisory together for manufacturers across California and nationwide, building product-level costing, reconciled inventory, and tax planning that accounts for capitalization rules and equipment decisions.
Where it gets complicated
- 01 Costs hidden in one line
Material, labor, and overhead often post to a single cost of goods sold account. Without a breakdown, you cannot tell whether a margin drop came from prices, waste, or a slow line.
- 02 Inventory that drifts
Raw materials, work in process, and finished goods move constantly. When counts and the books part ways, gross margin swings from month to month for reasons no one can explain.
- 03 Capacity decisions on instinct
A new machine, a second shift, or a large customer order changes your cost structure. Deciding without a model of fixed costs and throughput turns a major investment into a guess.
- 04 Tax rules tied to inventory
Inventory capitalization rules, small business exceptions, and equipment expensing all depend on how your books are built. Planning works best when the accounting and the tax return come from the same team.

Common questions
Do you work with manufacturers outside California?
Yes. TreeStar is headquartered in Chico with offices in Garberville, Sacramento, and San Francisco, and we serve manufacturers across California and nationwide. Documents move securely through the TaxDome client portal.
We use QuickBooks Online. Is that enough for a manufacturer?
For many small manufacturers it can be, with a well-designed item list, inventory setup, and month-end costing routine. We assess your operation and tell you plainly where QuickBooks Online fits and where a separate costing process is needed.
Where should we start if our costs feel unreliable?
Usually with a diagnostic review of the books and a recent inventory count. That shows whether the problem sits in purchasing, production recording, or overhead, and sets the order of fixes.
