Capture the part, condition, specs, photos, cost, and seller notes before the details disappear.
PC parts inventory and build planning
One workflow for PC parts, builds, costs, and sales.
PartPlanner turns scattered hardware, purchase costs, build notes, and sales decisions into a clear operating system for PC parts work.

The messy middle
Parts move faster than notes.
A used PC arrives as one purchase, parts get pulled into inventory, some hardware becomes a finished build, and other pieces are better sold separately. PartPlanner is built for that real operational mess.
Workflow
Track the path from incoming hardware to the right sale.
Organize inventory
Keep part inventory and build inventory separate, while still seeing which parts are assigned to which builds.
Assign parts to builds
Plan builds from hardware you already own and see exactly where each component is committed.
Choose the selling path
Decide whether the money is in a finished build or a part-out, then track that sale path without mixing the two.
Margins matter
Break down a purchased PC into real part costs.
When you buy a whole PC, PartPlanner can help turn one purchase price into a practical cost basis for every part. Compare allocated cost against expected resale value so you can decide whether to part it out, use pieces in a build, or sell the system whole.

Feature proof
Built for part inventory, build inventory, and resale decisions.
Inventory that knows hardware
Track model names, serials, specs, condition, images, cost, and current status in one practical view.
Build planning from real stock
Stop planning against a wish list. Assign actual parts to actual builds and spot missing components early.
Status movement
Follow parts from available to assigned or sold, and builds from planned to listed or sold without crossing the records.
Cost basis and margin
Break a purchased PC into parts, allocate the purchase cost across those parts, and compare that against expected sale value.
Team-ready operations
Give a small shop or reseller team one shared place to see what changed and what is blocked.
Part details and specs
Use structured specs where they help, while keeping the workflow flexible enough for messy incoming parts.
Listing context
Keep sale prep close to inventory and build records so marketplace work starts from clean information.
Product preview
Keep part inventory and build inventory clear.
A part can be available, assigned to a build, or sold on its own. A build can be planned, assembled, listed, or sold as a system. The records stay connected without pretending a part and a build are the same sale.
