  "instructions": "Condense the supplied vendor offers into a comparison for the stated purchasing need. Use this to organize quoted terms, not to recommend an investment or invent a procurement decision.\n\nCompare like-for-like units and scope. Retain currency, tax treatment, quantity, term length, mandatory fees, support, delivery, exclusions, and quote validity where supplied. Keep an optional feature outside the base offer. Do not rank prices that cover different periods or quantities as if they were equivalent.\n\nUse a compact table with the purchasing criteria as rows and suppliers as columns. Mark an unstated term as not supplied, rather than treating it as free, included, or absent. Note conditions that could change cost or readiness below the table.\n\nPreserve any source-backed disqualifier or unresolved question. Remove vendor slogans and duplicate descriptions. Do not estimate missing charges, calculate a total with unknown inputs, or select a winner unless the user separately requests a recommendation.",

    "before": "We need 20 lockers installed before the office opens on 1 September. Harbor's quote is GBP 4,000 excluding VAT for 20 lockers, including delivery and installation. Harbor says installation can be completed by 27 August if we accept by 5 August. Harbor includes a two-year warranty. Meadow quotes GBP 3,600 excluding VAT for 20 lockers with delivery included, but installation is quoted separately and no installation price was supplied. Meadow estimates delivery in the last week of August and has not confirmed an installation date. Its warranty is one year. Both quotes remain valid until 5 August. Neither supplier has confirmed whether it can anchor the lockers to our hollow-block wall. Harbor describes its lockers as market-leading; Meadow calls its service exceptionally flexible. The team has not selected a supplier.",
    "after": "Need: 20 lockers installed before 1 September. No supplier selected.\n\n| Term | Harbor | Meadow |\n| --- | --- | --- |\n| Price, excluding VAT | GBP 4,000 | GBP 3,600; installation price not supplied |\n| Included | 20 lockers, delivery, installation | 20 lockers and delivery |\n| Timing | Installed by 27 August if accepted by 5 August | Delivery estimated last week of August; installation date unconfirmed |\n| Warranty | Two years | One year |\n| Quote valid until | 5 August | 5 August |\n\nOpen for both: Can they anchor lockers to the hollow-block wall? Prices do not cover the same scope.",
