Purpose-built, not a spreadsheet

In many shops quoting still lives in a spreadsheet, nesting happens on a machine seat and weld procedure documentation lives in a folder. ShopCalcs gives each stage a tool built for it. Estimators build the take-off and quote from one model. Planners put usable offcuts back on the shelf. QC managers can show an auditor who signed off every joint.

  • Enter the job once. Geometry and material carry forward instead of being retyped
  • One stock library with grade, thickness, heat number and MTR reference
  • One subscription. Every seat includes all three apps, and you add seats as the shop grows
  • An auditable trail on every save, stamped with the person who made it
  • Nothing to install. It runs in the browser behind your own Microsoft Entra sign-in

Three apps, one subscription

Take what your shop needs

Each app is a standalone tool that keeps its own records. Every subscription includes all three, so the estimator, the planner and the inspector each get the one they need..

Vessel Estimator
Quoting & take-off

Build the vessel from its shell, heads, nozzles and supports, and get the material take-off, labour hours and quoted cost out of the same model.

Take-off by component, not by guess
Material priced from your own stock
Labour hours by process and position
Quote, cost breakdown and margin
Kerfworks
Plate nesting

True-shape nesting for plate fabrication. Produces the DXF cutting file and PDF job drawing, and books the leftover offcuts back into stock.

True-shape placement, per-part rotation
Kerf, spacing, edge margin, grain
Rolled cone and frustum flat patterns
Utilization, cut time and cost per job
WeldMap
Weld mapping & QC

Put the joints on the drawing. Every joint carries its symbol, procedure, approvals, signatures and history until the drawing closes out as a QC package.

AWS A2.4 symbols, all 14 weld types
WPS control with approval separate from assignment
Welder sign-off and VT / PT / MT / UT / RT results
Exportable QC package per drawing

Browser-based, behind your own sign-in

ShopCalcs runs in the browser and on shop-floor tablets. Sign-in is Microsoft Entra only, so there are no separate passwords to issue and no credentials stored in the app. Access is enforced on the server by role, so an estimator, a welding engineer and an inspector each see the queue that belongs to them.

ACCEPTANCE CODES IN WELDMAP

Configurable per joint

Set the acceptance code the joint is being inspected to, and the QC package carries it through. Every joint keeps its own record, so a drawing closes out as evidence rather than as a folder that happens to match it.

One subscription, priced per seat

Every ShopCalcs subscription includes all three apps. Add seats as your shop grows, and pay for the seats you actually use.

All three apps run in the browser and on shop-floor tablets. No workstation install and no machine-locked seats.

Your stock, your procedures

Data library

One plate and stock library and one WPS library, shared by the apps that need them. Remnants return to the same shelf the plate came from.

Heat numbers and MTRs

Traceability

Grade, thickness, heat number and MTR reference follow the material from stock into the nest, onto the joint and into the QC package.

Separation of duties

Controls

Assigning a procedure and approving it are two different jobs, and changing what was approved sends the approval back to pending. A signed joint locks, editing means reverting the sign-off, and the revert is recorded too.

Documents the shop can hand over

Reports

PDF job drawings, DXF cut files and printable QC packages, plus CSV and JSON exports into your own systems.

Works when the wifi does not

Floor-ready

Viewing keeps working from cached data, and sign-offs are queued and replayed on reconnect with a banner confirming the sync.

Feature requests welcome

Customization

We take custom requests and build them into the application, rather than handing you a script to maintain yourself.
