Capacity2 questions
From a single piece to a large series: not every job suits every business. These questions make clear which quantities and project sizes you can take on.
How it works3 questionsThis question needs attention now
Some customers want to hand everything over, others like to be involved. By explaining how you approach a job, you help AI match those different expectations.
Quality and guarantees3 questions
Anyone comparing businesses also looks for certainty. How long will something last? What happens if there’s a problem? Your answers help AI explain better what customers can expect.
Certifications and labels2 questions
For some searchers a quality mark is a plus; for others a specific certification is a hard requirement. That’s why we map out which accreditations you hold and what they cover.
Sustainability1 question
One person looks for reused materials, another wants less waste or a product that lasts longer. These questions make concrete which sustainable choices your business offers.
This is complete.
