About Us

Built to serve. Priced like a product. Owned like a craft.

Four Thirteen Studios is a software studio in Norman, OK. We build client websites and our own products on the same stack — and we bill the way we wish our own vendors would: a fixed number, direct invoice, no monthly retainer.

If that sounds like how you'd want to work with a studio, we'd love to hear what you're building.

Fixed-price quotes

We quote a number, we stick to it. Scope creep comes out of our margin, not your invoice. You always know what you're paying before the project starts.

No retainers

Most agencies lock you into monthly retainers to justify their overhead. We don't. Pay per project; come back for another when you need one.

Direct invoicing

No agency markup, no third-party billing platform taking 10%. You get an invoice direct from us, pay card or ACH, and own the relationship.

Based in Norman, OK

We're local to Oklahoma — available for in-person meetings across Norman, Moore, Edmond, and OKC, and remote-friendly for clients nationwide.

Transparent Pricing

Straightforward tiers designed to fit every stage of your business—from your first website to a full-scale digital presence. All plans are invoiced directly.
