PartDelta: BOM Revision

Compare Parts & Alternates

$0.99 · Designed for iPad. Not verified for macOS.

Compare any two BOM revisions: every added, removed, and changed part, the cost impact for your build, and an approval packet. One purchase, no subscription. PartDelta compares bill of materials revisions on your iPhone and iPad. Keep every revision of an assembly, pick any two, and see exactly what changed, what it costs, and what still needs a decision. Built for hardware startups, embedded teams, prototype labs, contract-manufacturing handoffs, and serious electronics builders. NEW IN 2.0: A REAL REVISION COMPARE Version 2.0 rebuilds PartDelta around projects that hold unlimited BOM revisions. Compare any two revisions and PartDelta matches lines reference by reference, so range lists like R1-R8 are expanded and a part that gains two designators shows as two added placements, not a vague "changed" line. Hardware without designators (PCBs, screws, labels) is matched by part number, then description. WHAT YOU GET - Projects with unlimited BOM revisions: copy the latest, start empty, or import a CSV - Revision compare: added, removed, changed, and unchanged lines with every changed field (MPN, manufacturer, quantity, unit cost, lifecycle, alternate, DNP) - Cost roll-up per assembly and for your build quantity - Cost drivers: see how much of a change comes from part swaps, price changes, quantity changes, additions, and removals - Change review: approve or reject each change with a note; review progress and open items stay visible - Change packet export: a PDF for your change board or contract manufacturer plus a CSV of every difference and decision - Where-used search: find every project and revision that uses an MPN, including where it is listed as an alternate - Lifecycle exposure: NRND and EOL parts placed in the latest revision of each project - Data checks: duplicate designators, missing MPNs, quantity versus designator mismatches, EOL parts without alternates, lines without cost - CSV import that understands KiCad, Altium, Eagle/Fusion, and spreadsheet headers, quoted fields, semicolon or tab separators, and decimal commas - Revision CSV export that re-imports cleanly - Backup and restore of the whole library as one file - Choice of currency, a BOM revision guide, and a sample project to explore EVERYTHING INCLUDED One purchase, no subscription, no account. Everything is stored on your device. No ads, analytics, tracking, or network access. Your PartDelta 1.0 comparison is converted automatically into a project with two revisions, and approvals are kept. PartDelta compares the BOM data you enter or import. Confirm design intent, schematic and layout revision, qualification evidence, lifecycle and sourcing data, compliance, manufacturer specifications, and formal change approval in your system of record.
