Materials account for 40-50% of project costs, yet 10-15% of those materials are wasted. Owners Inventory helps construction companies reduce that waste by giving teams real-time visibility into what they have, where it is, and when to reorder, so every dollar spent on materials is accounted for.

Construction businesses deal with daily operational challenges that affect project timelines, material costs, site efficiency, and budget control when inventory is managed without a proper system.
Ordering too much leaves materials sitting on-site for weeks, blocking cash that could be used elsewhere on the project. Ordering too little stops work and forces expensive last-minute purchases. Excess stock gets moved around, left out in the weather, or simply forgotten. Without tracking what's being used and what's piling up, the same purchasing mistakes get repeated on every project.
When materials are spread across multiple job sites, warehouses, and service vehicles, keeping an accurate count manually is nearly impossible. Teams make purchasing decisions based on memory or outdated records. Lack of visibility leads to duplicate orders, missed stock, and budgets that keep getting stretched project after project.
The construction industry loses an estimated $1 billion annually to theft in the US alone. Power tools, copper wire, and building materials are common targets. Most of these losses go undetected for days or weeks because there's no system recording what left the site and when. The project is already behind by the time the shortage is noticed.
When material purchasing is handled through phone calls, emails, and separate spreadsheets, errors are guaranteed. The same order gets placed by two different people. A delivery gets missed because no one followed up. Unapproved purchases go unnoticed because there is no approval process for orders before they are placed. Without a structured construction purchase order management process in place, each of these problems keeps repeating project after project.
Owners Inventory connects material tracking, purchase order management, site-level stock control, and supplier records into one system so construction teams always know what they have, what has been ordered, and what needs attention.
Our software updates stock levels automatically every time a material is received, used, or transferred between sites. Your team no longer needs to call around or walk a site to get an accurate count. Every site, warehouse, and storage location is visible from one place. That means fewer duplicate orders and fewer surprises when a delivery doesn't match what was expected.
Every purchase order is created, tracked, and approved inside the same system. No more orders placed through phone calls or separate spreadsheets. If an order is pending, received, or overdue, the status is visible to the people who need to know. Unapproved purchases can be flagged before they go through, so spending stays within the project budget.
Our software tracks how materials are being consumed across each project. When teams can see usage patterns, they order closer to what's actually needed rather than what's estimated. Overstocking drops. Materials are less likely to be left exposed on-site until they're damaged or lost. That waste reduction directly protects project margins.
Every item that enters or leaves a site is logged. Owners Inventory software keeps a clear record of stock movement, so stock errors are caught early rather than weeks later when the project budget reflects the loss. Teams can identify patterns and take action before small losses become large ones.
Our software keeps all supplier information and delivery schedules in one place. When a delivery is expected, the system shows it. When something is delayed, teams find out in time to adjust the work schedule rather than after a crew has already shown up at a site waiting on materials that haven't arrived.
Paper logs and Excel sheets get replaced with a system that updates in real time. Every stock movement, purchase, and material transfer is recorded automatically. Reconciling inventory no longer takes hours at the end of the week. The records are accurate because the process of keeping them accurate is built into how the system works.

Construction sites deal with hundreds of different materials, tools, and equipment at any given time. Owners Inventory lets you organize everything by category, type, unit of measurement, or location. Finding a specific item takes seconds instead of searching through a spreadsheet. Whether it's structural steel, electrical fittings, or heavy equipment, every item sits in its own category with its own stock record.
Every material and tool can be assigned a barcode or SKU inside the system. Scanning an item at the point of receiving or issuing it updates the stock count instantly. This removes the need for manual entry and the errors that come with it. Items are tracked from the moment they arrive on site to the moment they're used, transferred, or written off.
Each material can be given a minimum stock level. When quantities drop below that level, the system sends an automatic alert before the item runs out. Project managers get notified in time to place an order without stopping work. It replaces the habit of ordering in bulk just to avoid running short.
When materials are damaged, returned, or written off, the adjustment is recorded with a reason, date, and reference. Nothing disappears from the records without a trace. Every correction is logged, so your stock count stays accurate, and any audit trail is ready when it is needed.
Materials can be moved between job sites, warehouses, or storage yards using transfer orders that the system tracks at every step. If one site has unused stock and another is running low, the transfer is initiated and recorded from a single dashboard. No reconciling spreadsheets between locations. No phone calls to confirm what was sent.
Not everyone on a construction project needs access to the same information. Site supervisors, procurement staff, and project owners can each be given different levels of access. A site worker can log material usage without being able to edit purchase orders. Sensitive financial data stays visible only to the people who need it.
Owners Inventory follows a structured workflow that keeps every material, order, site record, and purchase history connected from the start of a project to its completion.
When a delivery arrives on site, it gets checked against the original purchase order inside the system. Quantities are verified and added to the stock count immediately. If there's a shortfall or a damaged item in the delivery, it gets flagged and recorded against that supplier before the delivery is accepted. Nothing enters the site stock without a record attached to it.
Once materials are received, they are assigned to a specific project or cost code inside the system. This step connects material spending directly to the project it belongs to. When a project manager reviews costs, they can see exactly how much has been spent on materials for each phase of work. It removes the guesswork from project cost tracking.
When a site team needs materials, the request is logged, and the stock count is updated at the point of issue. The system records who requested the materials, which project they were issued to, and when. This keeps consumption data accurate across every active project and makes it easy to spot when usage is running ahead of what was planned.
As materials are used, stock levels update automatically. Project managers can check remaining quantities at any point without walking the site. When a material approaches its reorder point, an alert is triggered so the order can be placed before work is affected. No manual stock checks between deliveries are needed.
When restocking is needed, a purchase order is created directly from the dashboard and sent through the approval process before it reaches the supplier. The right person reviews and approves the order, and once approved, it is logged against the project budget. When the delivery arrives, it is matched back to that purchase order automatically.
At the end of a project, the system generates a full stock reconciliation report showing what was ordered, what was used, and what remains. Leftover materials can be transferred to another site or recorded as unused stock. The report gives project owners a clear final picture of material costs against the original budget, without having to piece it together from separate records.

Every material purchase, supplier payment, and stock adjustment made through Owners Inventory is recorded against the project it belongs to. Project owners get a clear view of total spending across every active site without pulling records from separate systems. All billing activity sits in one place, so comparing actual costs against the project budget is straightforward at any point during active work, not just at the end.

Owners Inventory connects with accounting software so material costs, supplier invoices, and purchase order data flow directly into your financial records without manual re-entry. When a purchase order is completed and a delivery is confirmed, the transaction is available to sync with your accounting system straight away. This keeps project accounts accurate and reduces the time your team spends reconciling inventory records against financial statements at the end of each month.
Every stock movement, purchase order, and material adjustment in Owners Inventory is recorded with a timestamp and tied to the user who made the change. Nothing is edited or deleted without a record of it. This gives project owners a full audit trail across every site and every project without any extra effort from the team.
Role-based access control means each person on the project only sees and does what their role requires. A site worker logging material usage cannot edit purchase orders or view financial reports. A procurement officer can manage supplier orders without accessing data from other projects. Access is assigned based on each person's role and kept within those boundaries. Data is backed up automatically to encrypted cloud storage, so records are protected even if a device is lost or damaged on site. Your data is never shared with third parties or accessed outside your account. For construction companies subject to contract audits or compliance checks, every transaction record, adjustment log, and purchase history is stored and ready to be pulled up when needed.
Owners Inventory connects with the accounting tools your construction business already uses, so material costs, purchase orders, and project spending stay consistent across every system without manual data entry.
