The incentive problem
Hourly billing creates a perverse incentive: the slower the work, the more the agency earns. A junior developer who takes 20 hours to do a 4-hour task generates 5× more revenue than a senior who ships in 4. Agencies are run by people, so they hire the person who makes the books work — and that person is often the junior.
Scope creep is feature, not bug
Hourly agencies don't fight scope creep — they feed it. Every "what if we also added..." meeting is billable time. Every "let me check with the team" is billable. Every revision, every chat, every email thread is billable. The meter runs at $150-250/hour whether useful work is happening or not.
Why fixed-price fixes it
When a project is fixed-price, the agency's incentive inverts. Now we want the project done fast because every extra day eats into margin. We want the scope to stay clean because change orders are documented and signed. We want to ship on time because the client already paid for on time.
Our entire stack (Next.js, Vercel, OpenAI, Resend) is optimized for this. Modern tooling lets a senior engineer ship in a week what a junior at a traditional agency ships in a month. Fixed-price pricing captures the value of that speed.
What about unknowns?
This is the honest objection. "What if you hit something you didn't expect?" Good question. The answer: discovery. We spend a 30-60 minute discovery call mapping exactly what you need, then another 24-48 hours writing a detailed proposal. If we didn't uncover enough in discovery, that's on us, not on you.
When scope genuinely changes (you decide mid-project that you also need a blog, or you want to add Spanish), we send a written change order with a new fixed price for the addition. You sign it, we build it, you know exactly what you're paying. No surprise invoices.
Our last agency quoted $12k and we ended up at $38k over nine months. LobosTech quoted $6.5k and we shipped in five weeks. For exactly $6.5k. I don't know how to describe how much that mattered.
Red flags when hiring an agency
- They won't give you a total price up front
- The proposal includes vague phrases like "estimated 40-80 hours"
- They charge for meetings and calls
- They charge for "discovery" before you've even signed anything
- They won't commit to a delivery date
- The proposal doesn't list specific deliverables
The rule of thumb
If you can't get a total fixed price on a one-page proposal after a 30-minute discovery call, walk away. The agency either doesn't know what they're doing or is planning to bill you by surprise. Neither option ends well.
