First make every supplier quote the same job
Two quotes are comparable only when they aim at the same workpiece result. Define the substrate, the layer to remove, the permitted surface change, the complete-part cycle time, the annual volume, the operating pattern and the site conditions. If one supplier is quoting a visual rust-removal demo and another is quoting a validated preparation process for bonding, their prices should not match.
Next, define the delivery boundary. Does the price stop at the laser cabinet and handheld head? Or does it include extraction, an enclosure, fixtures, interlocks, controls, training, freight, commissioning and acceptance testing? A quotation can be accurate and still be incomplete for your site.
Send every supplier the same representative samples and the same written acceptance criteria. Ask them to list every inclusion, exclusion, utility and buyer responsibility. This turns a confusing price comparison into an engineering comparison.
If you are still deciding which architecture fits the task, use the laser cleaning machine selector and the application feasibility checker before requesting final quotations.
