How to read the report

The important details stay visible from summary to individual ISBN

Start with the portfolio-level totals, then move into the rows to understand which books create the result. Every number remains connected to a specific vendor and action.

01

Review the totals

The summary cards combine the displayed ISBNs into purchase cost, potential sale revenue, and net estimated profit or loss.

02

Choose the right view

Switch between Sell, Buy, and Arbitrage without running the search again. Each tab reorganizes the same completed vendor data around a different goal.

03

Narrow a large inventory

Filter by minimum sell price, minimum profit, or vendor. Use “Profitable only” when you want to temporarily hide loss-making comparisons.

04

Understand every row

Green badges show positive spreads and red badges show losses. Buy and Sell buttons take you to the vendors behind those exact prices.

Built to make a large list manageable

See the opportunity—and the risk—before you act

A bulk report does more than return prices. It gives every ISBN the same decision-ready structure, so promising books rise to the top and weak spreads remain visible instead of disappearing from the analysis.

01

Prioritize the strongest books

Sort sell offers and estimated spreads so the inventory most worth your attention appears first.

02

Compare vendors side by side

See where to buy and where to sell, with direct vendor actions attached to each ISBN result.

03

Keep losses visible

Positive and negative spreads use clear color cues, helping you avoid inventory that looks attractive until the full cost is compared.
