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.

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.
Convictions
Why we work the way we work.
Four Thirteen Studios is owned and operated by a Reformed Christian. The name is the verse — Philippians 4:13 — and the studio's business practices are downstream of a few specific theological convictions. We are not a "faith-based agency" in the sense of only working with churches or ministries. We work with clients of any background. But the way we work is shaped by what we believe, and clients deserve to know that up front.
Stewardship, not extraction
Our pricing model — fixed-price quotes, no retainers, direct invoicing — is a stewardship decision before it is a business decision. Hourly billing on a project the studio could quote concretely is a soft form of extraction: the longer it takes, the more we get paid. Retainers that outlive the work are the same problem stretched over months. We'd rather quote a real number, ship the work, and let the relationship continue because the client wants to come back — not because an auto-renewal made it inconvenient to leave.
Honesty in scope
We tell you what's in scope, what's out, and where we are uncertain — in writing, before the invoice. We tell you when we're not the right shop for a build and recommend someone who is. The ninth commandment is not a marketing slogan; it is a constraint on how we describe what we can and cannot do.
Work as vocation
We believe writing software is a real vocation — not a sideshow to "real ministry," not merely a means of funding other things. A well-built site that helps an Oklahoma HVAC operator route real leads at midnight, in summer, with no AC, is itself good work. We try to do it well because the work itself matters, and because the One we ultimately answer to sees what we ship.
Coram Deo
The phrase means "before the face of God." Practically, it means we write code, send invoices, write quotes, and answer email under the same standard whether the client is watching or not. It is the most concrete reason we keep the price on the quote equal to the price on the invoice — even when scope creep would let us bill more without anyone noticing.
Sola gratia, sola fide, solus Christus, sola Scriptura nos salvat — soli Deo gloria!
