How a retail buyer prepares for a supplier negotiation
A retail buyer prepares for a supplier negotiation by reading how the supplier's lines traded and turning that evidence into asks and walk-away points.
The evidence covers sales, margin, sell-through and availability, the lines at risk in the next range review, promotion results and funding, price position and supply problems. After the meeting, the buyer records what was agreed and who owns each follow-up.

Step by step
Read how the supplier's lines traded
Pull sales, gross margin, sell-through and availability for each of the supplier's lines over the same period. A line that was out of stock can look weak when it isn't, so compare its weekly units when in stock with its plain average. GMROI shows whether a line is earning margin by moving stock quickly or by carrying a high margin on slow sales.
Name the lines at risk in the next range review
List the supplier's lines that fall below the category's review line before the next range review. Group them by shopper need, so you know whether a delisting would remove the only option for a need. If the supplier is the category's category captain, check its range and shelf recommendations against your own sales, margin and shopper data, because it also benefits from its own lines getting space.
Check promotion results and funding
For each promotion the supplier funded, look at what it did to the whole category, not only to the promoted line. Promotional incrementality is the share of promoted sales that would not have happened without the promotion. A funded promotion can lift the line's units and still lower category gross profit if it takes sales from own label and other lines.
Compare price position on matched lines
For lines matched against the market, check where your price sits: your price position. Confirm each match is the same product and pack size before treating a gap as a reason to move. Published prices say nothing about a competitor's costs or supplier funding, so a gap is a question to put to the supplier, not proof of their terms.
Collect the supply issues
List each stockout that followed a late or short delivery, and estimate the lost demand: sales that never appear in a report because the line was unavailable. In the illustrative chilled-desserts example on the range review page, sticky date pudding averaged 45 units a week over 12 weeks, but it was out of stock for 5 of them after a supplier issue. In the 7 weeks it was available it sold 77 a week. That gap is a supply point for the meeting, separate from what shoppers wanted.
Set the asks and the walk-away points
Write down what you want from the meeting, each ask tied to evidence from the steps above: a fix for a line that kept running out, funding for promotions that added to the category, or terms for a line at risk in the review. For each ask, decide beforehand the point at which you would walk away, and check it against your margin floor and approval limits.
Record what was agreed and who owns the follow-up
After the meeting, record each agreement with the evidence behind it, the person who owns the follow-up and the date to check it happened. In twelfth that entry is a decision record: a permanent, timestamped entry holding what was committed and what was recommended.
