How do I track inventory for a construction business?
Most materials in construction aren’t really inventory in the accounting sense. They’re job costs. The distinction matters because it changes how you track them and where they show up in your financials.
When you buy lumber for a specific remodel, that’s not inventory sitting on a shelf waiting to be sold. It’s a cost that belongs to that job. Code it directly to the project in your accounting software and move on. Don’t complicate things by running it through inventory first.
True inventory for contractors means materials you keep in stock before knowing which job they’ll go to. Common examples include electrical fittings, plumbing parts, fasteners, or specialty materials you buy in bulk because it’s cheaper. These items sit in your shop or warehouse until they’re pulled for a specific project.
For tracking stock materials, start with what you actually keep on hand. Most contractors don’t need to track every box of screws. Focus on items with real dollar value that you purchase regularly and store before use. Set up inventory accounting in QuickBooks or whatever software you use. Each item needs a cost, description, and reorder point if you want reminders when stock runs low.
Physical organization matters as much as the accounting side. Keep stock materials in one location, labeled clearly. Running out of fittings mid-job because nobody knew the bin was empty costs real money even if it doesn’t show up on your books.
Count inventory periodically. Once a quarter works for most contractors. Compare what’s physically there to what your books say you have. Shrinkage happens through theft, damage, miscounting, and materials that got used but never recorded. Adjust your books to match reality.
When materials get pulled for a job, record that transfer so the cost moves from inventory to the specific project. This is where inventory tracking meets job costing. The material value leaves your inventory account and becomes a direct cost on that job.
The real question most contractors should ask is whether they need inventory tracking at all. If you’re buying materials for specific jobs and using them within days, bookkeeping services in American Fork focused on job costing handles everything you need. You only need formal inventory accounting when you’re holding materials before assigning them to projects.
If your shop has $20,000 in materials sitting on shelves at any given time, track it as inventory. If you buy what you need for each job and use it immediately, skip the inventory complexity and focus on coding costs to the right projects.

Contractors should review profit and loss statements, balance sheets, job cost reports, work in progress reports, and aging reports for receivables and payables. The job cost report matters most because it shows actual profitability by project rather than just overall company numbers.
Read answerWhy is tax time always so stressful?

Read answerCan QuickBooks handle job costing for construction?
Yes, QuickBooks can handle job costing for construction if it's configured correctly. Default setup won't work because it tracks expenses at the company level, not by job. Proper configuration includes enabling jobs, setting up construction-specific categories, and coding every transaction to the right project.
