Written and reviewed by Seller Profit Guard Editorial Team.
Add loaded labor cost, one-time tools and setup, creative adaptation, old-and-new platform overlap, and modeled lost contribution. Divide labor hours by approved weekly capacity for implementation time. Divide total migration cost by post-migration contribution per mature retained order and round up for payback volume.
Define scope
Add loaded labor cost, one-time tools and setup, creative adaptation, old-and-new platform overlap, and modeled lost contribution. Divide labor hours by approved weekly capacity for implementation time. Divide total migration cost by post-migration contribution per mature retained order and round up for payback volume. Keep scope, labor, nonlabor cost, overlap, lost contribution, capacity, contribution, forecast, authorization, and restoration separate. Checkpoint 1 in the migration cost ledger records source and target channels, product scope, permitted-data boundary, catalog version, URL plan, integration register, currency, labor categories, loaded rate, nonlabor costs, owner, reviewer, authorization boundary, monitoring trigger, and restoration before interpretation.
For define scope, keep catalog, cleanup, storefront, integration, URL, training, test, rate, app, setup, creative, other, overlap, lost contribution, capacity, retained-order contribution, forecast, threshold, and conflict in separate evidence fields.
Use invented or approved non-identifying aggregates only. Exclude buyer or customer names, emails, addresses, order rows, payment details, identifiers, credentials, invoices, customer lists, private exports, and account data from the public migration cost ledger.
