We accept
IO Windows accepts all major credit cards through our secure checkout, powered by WooCommerce. Your card is charged only after a window specialist has reviewed your order and confirmed every detail with you personally.
Zero down, zero interest financing
We offer zero-down, zero-interest financing for 12 months on qualifying orders. Spread the cost of your new windows or patio doors into affordable monthly payments with no upfront cost and no interest charges.
- $0 down — nothing due at the time of order
- 0% interest for 12 months
- Quick application during order review
- No prepayment penalties
Financing details are discussed when our team contacts you to review your order. We’ll walk you through the application process — it only takes a few minutes.
When is payment collected?
We don’t charge your card the moment you click “Place Order.” Here’s how it works:
- You place your order — your card is authorized but not charged
- We review your order — a specialist confirms your options, sizes and total
- You approve — only then is payment collected and your windows go into production
If you requested professional installation, our Hallmark crew field-measures your openings before production begins. You’re never committed to an order you haven’t personally confirmed.
Your information is safe
We respect your privacy and take data security seriously. All transactions are processed over encrypted HTTPS connections. We never store your full credit card number — payment processing is handled entirely by our PCI-compliant payment gateway. Your personal information is used only to process and fulfill your order.
