Quoting container space in minutes — a use case for freight forwarders & 3PLs
Freight forwarding & 3PL
A use-case guide for Freight forwarding & 3PL teams to apply to their own operation — not a specific customer story. The workflow and ContainerMath features shown are real; the figures illustrate what this use case typically targets rather than results measured from one account.
A use-case guide for freight forwarders and 3PLs: how to quote how much cargo fits a 20ft or 40ft container the same day and stop giving paid-for space away — by reusing a shared box library of recurring client SKUs, confirming the 3D fit before a number goes out, and pricing on whether a load is space-limited or weight-limited.
The challenge
A forwarder's competitive edge is answering 'how much of this fits, and what will it cost to ship?' faster and more accurately than the next desk. Yet most teams start every quote from a blank spreadsheet: re-keying each client's carton dimensions, summing CBM by hand, and estimating fit from memory of past loads. Quotes that need a planner's judgment slip to the next day, and conservative guesses leave paid-for space empty — or, worse, promise space that doesn't actually fit once the cargo arrives, triggering a re-book. This guide walks the workflow ContainerMath replaces it with.
Before vs. after
- 1Re-key client dimensions every quoteEach enquiry meant copying carton specs out of an email or PDF into a fresh sheet — the same SKUs, re-entered for every client, every time.
- 2Estimate fit from experienceWhether a load needed one 40ft or spilled into a second container came down to a planner's recall of similar shipments, not a verified layout.
- 3Sum CBM and payload by handVolume and weight were totalled in Excel with no live check against the container's limits, so weight-out vs space-out wasn't obvious until loading.
- 4Quote, then hopeThe number went to the client before anyone confirmed the cargo physically fit — over-promises surfaced at the dock as re-bookings and amended invoices.
- 5Hand the warehouse a bare numberOperations received a CBM figure and a container size, with no stuffing plan, so the floor still had to work out the actual stack.
- 1Reuse every client's cartons from the Box LibraryRecurring SKUs are saved once and pulled into any quote — no re-keying dimensions out of email for the tenth time.
- 2Confirm the fit in 3D before quotingContainerMath places the cargo and shows utilization against the chosen container, so the quote is backed by a layout that actually fits.
- 3See space-out vs weight-out instantlyLive CBM and payload reveal whether a load is volume-limited or weight-limited, so the right container — and the right price — is chosen on data.
- 4Compare 20ft, 40ft and HC in secondsSwitching vessels recomputes the fit immediately, making it obvious when consolidating into one larger box beats booking two.
- 5Send the client a real loading planThe quote ships with a 3D plan and PDF the client and warehouse can both act on — a more credible answer than a bare CBM number.
Inside ContainerMath: the parts they used
The results
- Space quotes that need a planner's judgment can go out the same day instead of slipping to the next.
- Confirming the 3D fit before quoting reduces over-promised space and the re-bookings it causes.
- A shared box library ends the per-quote re-keying of recurring client dimensions.
- Seeing space-out vs weight-out up front means dense freight is priced on the limit that actually binds.
