Which document is legally binding, the quote or the confirmation?

Generally, a quote is an 'invitation to treat' and the order confirmation represents the acceptance of a contract. If the confirmation differs from the quote and you do not object, you may be deemed to have accepted the new terms.

What should I do if the price on the confirmation is higher than the quote?

Review the quote's validity period. If the quote is still valid, notify the supplier of the discrepancy. If the quote has expired, the supplier is usually entitled to apply new pricing, though many will honour the original price if asked.

Is a verbal quote valid for cross-checking?

Verbal quotes are difficult to verify. Always request a written summary or a 'soft' quote via email before an order is placed so you have a digital paper trail to compare against the formal confirmation.

How to Cross-Check a Quote Against an Order Confirmation

21 July 2026 · 3 min read

When a supplier sends an order confirmation, it is easy to assume it perfectly reflects the quote you accepted. However, administrative errors, system glitches, or updated pricing tiers can lead to discrepancies. Failing to catch these differences early often results in overpayment or receiving the wrong goods. To protect your margins and timelines, you must systematically cross-check the two documents before the order is processed or invoiced.

The Systematic Review Process

The most effective way to cross-check is to place both documents side-by-side. Start with the 'macro' details before moving to the specific line items. If your company uses a Purchase Order (PO) system, you should actually be comparing three documents: the initial quote, your PO, and the supplier's confirmation.

Check the high-level details first. Ensure the billing address, delivery address, and contact names are identical. A small error in a postcode or a department code can cause significant logistical delays that are difficult to rectify once the goods have left the warehouse.

Key Data Points to Verify

Once the header information is confirmed, you must perform a granular review of the goods or services listed. Discrepancies often hide in the fine print of product codes or unit measures.

Focus on these specific elements during your comparison:

Product Codes/SKUs: Ensure the confirmed part numbers match exactly what was quoted.
Quantities and Units: Look for errors such as 'cases' being interpreted as 'individual units'.
Unit Pricing: Verify that any agreed discounts or volume-based pricing have been applied correctly.
Incidental Costs: Check that shipping fees, insurance, or fuel surcharges match the original estimate.
Lead Times: Ensure the delivery date on the confirmation aligns with the urgency stated in the quote.

Handling and Resolving Discrepancies

If you find an error, do not assume the supplier is aware of it. Most order confirmations are generated automatically by ERP systems. Contact the supplier immediately via email, referencing the specific quote number and the exact line item that is incorrect. Do not authorize payment or acknowledge the confirmation until a corrected version is received.

For businesses handling high volumes of paperwork, manual checking is often the point of failure. Tools like Jittan’s DocumentChecker can automate this stage, allowing you to compare documents and schedules to spot mismatches or omissions instantly without the risk of human oversight.

Taking ten minutes to rigorously verify an order confirmation against a quote prevents hours of administrative work later. A consistent, detail-oriented approach ensures that what you pay for is exactly what you receive.
