How to check a window order confirmation before approval
An order confirmation records what your supplier has understood and accepted from your order. Before approving it, compare each window with the order you sent and any changes agreed in writing.
Match the same item, the same revision and the same units. Missing information still needs clarification, even when no difference is detected.
1. Gather the correct versions
Use the order actually sent, the supplier confirmation and any written amendments. Check the order number, project, date and revision. Match windows by item reference or room, since the rows may appear in a different order.
2. Check every window
Review the same fields for every item. This checklist supports document review; it does not replace a site survey or the manufacturer’s instructions.
Reference and quantity
Match item references and descriptions. Check quantities on each line, including identical windows in different rooms.
Width and height
Check units and measurement conventions. Opening dimensions, manufacturing sizes and overall frame dimensions may describe different measurements. Clarify these before treating a difference as an error.
Installation and configuration
Compare installation type, frame, accessories and number of sashes. Include explicitly requested options.
Opening direction
Check both wording and drawings using the supplier’s stated viewpoint. Inside and outside views can be read differently.
Colour and finish
Distinguish inside from outside colour, colour reference and finish. A generic description is not enough when a specific reference was ordered.
Glazing
Compare the stated composition and any safety, acoustic, solar-control or appearance requirements in your order. A missing field does not confirm the requested specification.
Price and delivery
Check unit prices, quantities, discounts, charges and total using the same tax basis and currency. Distinguish dispatch from delivery dates and check the delivery address.
3. Example: three points to clarify
Fictional example, item F01. Both documents specify overall frame dimensions in millimetres, so the width values are comparable.
| Check | Order sent | Confirmation | Action |
|---|---|---|---|
| Overall width | 1,200 mm | 1,250 mm | Ask for confirmation or correction of the 50 mm difference. |
| Outside colour | RAL 7016 | RAL 9016 | Ask the supplier to confirm the ordered colour reference. |
| Glazing | Composition specified | Not stated | Request the complete specification in writing. |
If one dimension referred to the opening and the other to the manufactured frame, clarify the measurement conventions first. Subtraction alone would not establish an error.
4. Clarify and recheck the revised confirmation
State the order number, item reference, ordered value, confirmed value and requested correction. Include the relevant extracts and ask for a written clarification or revised confirmation. Review the whole item again when it arrives, then retain the approved version and correspondence.

Frequently asked questions
Can I approve automatically if no differences are found?
No. No detected difference does not guarantee complete reading or technical compliance. Review the originals, drawings and missing information.
Should I check every line?
Yes, including apparently identical items. Quantities, options or orientation can differ.
What if the confirmation is a scanned PDF?
Text recognition can misread digits or miss labels. Check extracted values against the PDF and correct them before comparing.
