![Aerial view of a bulk material yard with large irregular stockpiles](https://rebulk.com/_next/image?url=%2Fwood-chip-yard-aerial.jpg&w=3840&q=75&dpl=dpl_8Ew6T9tu4Dd3SVVfPsxQaFRznR2X) [Solutions](https://rebulk.com/solutions) # Measure your inventory instead of estimating it. Counts happen on a calendar. Material moves every day. Rebulk measures what is actually on the ground, in the silo, and in every railcar, so the number you bill from and the number you have are the same number. [Book a Demo](https://rebulk.com/contact) [Read the Charm Industrial Story](https://rebulk.com/customer-stories/charm-industrial) Why it happens ## The number was never measured in the first place Inventory accuracy rarely fails at one point. It erodes between counts, through assumptions nobody wrote down. ### Counts happen on a calendar A pile gets measured at month-end or quarter-end. Material moves every day in between, so the number on the books is an estimate that quietly drifts until the next count corrects it. ### Estimates carry assumptions Visual estimates, loader counts, and bulk volume approximations get layered with density assumptions. Each one is defensible alone. Stacked together, they move the number by hundreds of tons. ### Survey results arrive after they mattered A third-party survey takes days to come back. By the time the report lands, the pile has been drawn down and rebuilt, and the number describes a yard that no longer exists. ### The pile and the paperwork live apart Scale tickets sit in one system and physical inventory in another. Shrink shows up as a month-end surprise, and a customer dispute becomes two sets of numbers with no way to settle between them. How far off is your last pile estimate?

How Rebulk solves it ## A measured quantity, kept current Rebulk Inventory builds a 3D model of the pile and the ground underneath it from LiDAR, drone, or mobile capture, then turns that into tons. Small errors in the baseline distort volume at scale, so the ground gets modeled too rather than assumed flat. Rebulk Transload keeps each measured quantity attached to the customer, commodity, location, and railcar it belongs to, so storage billing and customer reporting rest on ground truth. Measured inventory drives the reports and invoices your customers see. - Measured volume, not a running tally - Ground surface modeled, not assumed flat - Capture works offline and syncs later - Every measurement is a point on a trend line ![Rebulk inventory dashboard charting bulk inventory levels over time by customer and commodity](https://rebulk.com/_next/image?url=%2Frail-transload-inventory-over-time.png&w=3840&q=75&dpl=dpl_8Ew6T9tu4Dd3SVVfPsxQaFRznR2X) On-hand quantity by customer and commodity, tracked over time. Products involved ## Measurement and ownership, live today Know what's on the ground, in the silo, and in every railcar — without a manual count. The measurement Rebulk Inventory LiDAR, drone, and mobile capture turned into a 3D model of the pile and the ground beneath it, then into tons. Continuous at sites where material moves daily, on demand everywhere else. [Explore Inventory](https://rebulk.com/products/inventory) The ownership Rebulk Transload Keeps every measured quantity attached to the customer who owns it, the commodity, the location it sits in, and the railcar it arrived on.

The workflow ## From a photo to a number you can bill from Six steps, and only the first one happens in the yard. 1. 1 ### Capture Fly a drone, walk the pile with a phone, or leave a fixed sensor running. Field teams take photos; that is the whole job. 2. 2 ### Model Overlapping images become a dense 3D model of the pile and the ground surface under it, because bulk yards are rarely flat. 3. 3 ### Measure Bulk volume and packing factor give usable material, so piles with different internal structures compare on equal footing. 4. 4 ### Attribute Tons land against the customer, commodity, and location they belong to, alongside the railcar that delivered them. 5. 5 ### Track Measure the same site again and you have a trend instead of a snapshot: how piles grow, deplete, and move over time. 6. 6 ### Reconcile Measured on-hand sits next to receipts and shipments. Shrink surfaces while you can still do something about it. Proof ## Charm Industrial measures piles nobody could count Charm's feedstock is log piles from wildfire resilience projects and corn stover baled in fields, stacked on sloped, uneven ground across remote sites. With Rebulk, operators capture scans on standard mobile devices and sync them later, which matters when the yard is in mountainous Colorado with spotty cell service. Accuracy across measured biomass inventory Greater than 95% Field team effort Take photos > “Accurate measurement turns irregular piles into actionable data. Actionable data supports better operations. Better operations support scale.” [Read the Charm Industrial story](https://rebulk.com/customer-stories/charm-industrial) ![Packing factor analysis showing void fraction in a biomass pile](https://rebulk.com/_next/image?url=%2Fbiomass-packing-factor-v2.jpg&w=3840&q=75&dpl=dpl_8Ew6T9tu4Dd3SVVfPsxQaFRznR2X) Packing factor analysis: how much of a pile is material, not air. ## Put a measured number under your inventory Send us one site: the material, the storage, and how you count it today.
