FAQ

Common questions from procurement teams.

Do you support purchase orders (PO)?
Yes. Provide your PO number on the quote form or at checkout — it's referenced on the Stripe Invoice and on every shipment's packing slip.
What payment terms do you offer?
Approved government accounts default to Net-30. Net-15, Net-45, and Net-60 are available on request.
How do we get tax-exempt status applied?
Email a copy of your tax-exempt certificate to support@stampedsidewalks.com. We mark your account exempt before your first invoice.
Are stamps grant-eligible?
Sidewalk poetry installations are often funded through public art and placemaking grants — eligibility depends on your grantor. We'll provide quotes formatted to your grantor's requirements.

Bring sidewalk poetry to your city — within budget and on terms.

Send us your scope; we'll return a grant-ready quote within one business day.
