What we changed in BuildTrace, newest first.

October 2026

BOMs and parts, Inventory

Where-used lists and editing locations and suppliers

A part’s Where-Used tab now lists the assemblies that use it. It shows direct uses, with the ECO that added the part, and uses through sub-assemblies, with the level, the path and the quantity per unit. If you can read production, it also lists the open build orders that will consume the part. Pick a revision to narrow the list. Each assembly links to its BOM.

Locations and suppliers can now be edited. On Inventory, the Manage locations panel has Edit, Deactivate and Reactivate. You can change a location’s name, kind and notes, and its code until something refers to it. A location cannot be deactivated while it holds stock or units, or while an open build order uses it, and the message says how many.

Suppliers have the same on the Suppliers page: edit the name, contact and notes, then deactivate or reactivate. Both pages hide inactive entries unless you turn on “Show inactive”.

Inactive locations and suppliers drop out of the pickers for receiving, transfers and new build orders. They stay in history and in filters.

Production, Quality

Final test plans for each revision

Each revision can now have its own final test. In the process editor, a Final test section sits under the work instruction. Add checks as a measurement with a unit, limits and target, a pass or fail, or a recorded value. Each check is required unless you untick it, and can carry instructions for the operator. A draft process ECO can replace the plan.

The produce wizard shows the checks for the revision being built, one field per check. It marks each measurement in or out of spec as the operator types, and shows an overall pass, fail or in progress. A revision with no plan says so and does not block production.

The server judges the results against the plan. If the plan changed while the operator was testing, the wizard reloads it and asks for the results again.

A unit that fails its final test is not lost. The operator can choose “Finish as failed”. The unit gets its serial number and a failed final inspection, and is quarantined for rework, retest or scrap.

The unit page shows the final test as it was when the unit was built: plan version, each result against its limits, and every inspection of the unit. The build order’s Units tab has a new Final test column.

Production

Manuals and images in work instructions

Work instruction steps can show photos and diagrams. In the process editor you add an image from the assembly’s files or upload a new one. Each image needs alt text and can have a caption. You can reorder and remove them. PNG, JPEG and WebP files up to 10 MB are accepted. Operators see the images in the produce wizard, and each unit’s page shows the images that were in force when it was built.

A step can cite a manual. Manuals now have their own file kind, and a step’s manual picker has a “Upload a manual” link, so you no longer need to file a manual as a datasheet first. The limit is 32 MB per file.

Each substep can name its page in the manual. While an operator works through the substeps, the manual pane opens at the page of the first substep not yet ticked. A substep’s page is a link that moves the pane there. The unit’s record keeps these pages too.

Inventory

Reorder points and stock counts

You can now set a minimum stock level for each part, and optionally a quantity to reorder. Set it from the Stock page or from the part’s Summary.

Stock marks a part “Below minimum” when its available stock, across all revisions and locations, is under its own minimum. Parts without a minimum are never marked. Available stock leaves out what open build orders hold, and for serialized parts it leaves out quarantined units.

The new Below minimum tab on Inventory lists each shortfall with the available quantity, the minimum and the quantity to reorder. You can edit the minimum on any row.

The dashboard shows a banner with the number of parts below their minimum and links to that tab.

Units that leave stock also count against the minimum. That covers quarantine, scrap, shipping, a failed inspection, a return for repair and deployment, as well as reservations and write-offs.

You can also record a stock count. To correct a lot after a count, expand a material on Stock, open “Adjust” on the lot, and enter the counted quantity and a reason. If the lot changed since you opened the dialog, the adjustment is refused and tells you the new quantity on hand.

Platform

Setup checklist for new workspaces

A new workspace now shows a “Set up your workspace” card on the dashboard. It has four steps: add your first product, add a location, receive your first stock and invite your team. Each step opens the form or dialog where you do it, and it ticks itself off when you finish. You can dismiss the card, and it goes away once all four are done.

The “Add a product” wizard names the product, lists what goes into it and says for each part whether it is tracked by quantity, by serial number or built by you. You can paste or upload a CSV of parts, check a preview of what is new and what you already have, and then create the product.

Empty pages now tell you what to do first. Parts and BOMs offers “Add a product”, and Inventory asks for a location before anything else.

Quality, Field and service

Lot inspections, recalls by revision, and unit actions

On the Quality page you can now record an inspection for a lot, not only for a single unit. Pick a raw part revision and a lot number. The page tells you whether the lot is now blocked or usable.

A lot whose latest inspection failed is blocked. It cannot be transferred or built into units, and its stock stops counting towards reservations. A passing inspection releases it.

A recall can now start from a part revision, for example a bad board revision, as well as from a lot or a supplier. It finds every unit of that revision, including spares in stock and units built or reworked with it, and the finished units they went into. Each result shows where the unit is now: its location, the unit it is built into, or its fleet, customer and site if it is in the field.

From the results you can select units and quarantine those still in stock, or open a rework order for each one. You can also export the results as a CSV.

Each unit page now lets you move, quarantine, scrap or release the unit, depending on its status and your role. Scrapping needs a reason and cannot be undone. A unit whose latest inspection failed cannot be released until a passing inspection is recorded.

Platform

Manage members and ownership

Settings now lists your members above the invites. You can change a member’s role or remove them, and the app only offers the roles you are allowed to give.

Removal and revocation take effect on the next request. A removed member is signed out of the organisation, and a revoked service account can no longer sign in.

Every organisation has at least one owner. An owner can make another member an owner, and can step down at the same time to hand over ownership. Nobody can remove an owner or change an owner’s role. An owner can give up their own ownership and stays an admin, as long as another owner remains.
