Costs are a dated ledger, frozen as of each sale. A later correction restates past orders, and the view as recorded at the sale is kept beside it.
Agents and AINot stated on the pages we read.Agents create and publish offers through the API and MCP. Nothing goes live until a real Storefront cart charges what the offer promises.

Where Fast Bundle wins

Where Offer Suite is different

  • Offer Suite's pricing includes shipping and subscriptions: a bundle's single label and pick and pack, free shipping, and the renewal margin at the subscribe-and-save price.
  • It tracks realized profit per option after the sale, renewals, refunds and cancellations included.
  • Nothing goes live until a real Storefront cart charges what the offer promises.

Questions

Is Offer Suite a Fast Bundle alternative?

For measuring and verifying bundles on profit, yes; for a ready-made bundle widget, no. Offer Suite's bundle calculator is on this site and free to use either way.

What does Fast Bundle's calculator leave out?

Its page lists product costs, fees and a returns reserve, and doesn't mention shipping costs or subscriptions. A bundle's shipping saving is usually the main reason it can be discounted.
