How AI Is Changing What Your Developer Actually Bills You For

If you’ve worked with the same developer for a few years, your bills probably look a little different in 2026 than they did in 2023. Some things cost less. Other things cost more. A few categories of work have simply disappeared. The reason is AI — and it’s worth understanding the shift, because it affects how you should scope your projects and what you should expect to pay for.

What’s gotten cheaper

A lot, honestly.

Boilerplate code. The first hour or two of any project used to be spent writing the same scaffolding every time — routes, models, basic CRUD operations, form handlers. Developers now generate this in minutes with AI assistance. If you’re billed for “setting up the project,” that line item should be smaller than it used to be.

Documentation. Writing clear comments and internal docs used to be a real time investment. AI can draft decent documentation based on the code, and developers review and refine instead of writing from scratch. Same output, a fraction of the time.

Simple refactors. Renaming a function across a codebase, converting to a new syntax, reformatting code to match a new style — all of these used to be slow and error-prone. AI handles them reliably now, with human review.

Translating between languages. Porting a script from Python to JavaScript, or PHP to TypeScript, is something AI does well. It’s not perfect, but the human’s job has shifted from “do the work” to “review the work,” and that’s much faster.

Looking up how to do something. Developers used to spend a real chunk of their time searching Stack Overflow and reading documentation. AI short-circuits that — you describe what you want and get a working answer. Junior developers especially benefit, and the time savings flow through to your bills.

What’s gotten more expensive

Here’s the less-advertised side.

Judgment work. When most of the code is easy, the hard parts stand out more. Architecture decisions, product tradeoffs, edge cases, unusual requirements — these haven’t gotten easier. If anything, they’ve become a bigger share of every invoice because the routine work no longer fills the hours.

Good developers are leaning into this. You’re paying less for typing and more for thinking. That’s generally a good trade — the thinking is what determines whether the project succeeds.

Integration and glue work. AI is great at writing isolated code. It’s less good at connecting complex systems — an API talking to a database talking to a third-party service with specific authentication rules. These integrations often need a human who understands the whole picture. That work hasn’t sped up much.

Debugging the weird stuff. AI helps with routine bugs. It’s much less helpful when a bug is caused by an obscure interaction between three systems, or a race condition, or a caching issue that only shows up in production under specific conditions. Those bugs still take time, and they’re a bigger share of what gets billed.

Code review and oversight. Every line of AI-generated code needs a human check. Developers are spending more time reviewing than before, and rightly so — AI writes fluent-looking code that sometimes does the wrong thing, and catching those cases requires expertise. This isn’t wasted time, but it’s time.

What’s disappeared entirely

Some work has just stopped being billable:

• Hand-writing unit tests for straightforward functions (AI drafts, human reviews)
• Formatting data files, converting CSVs, cleaning up JSON — work that used to be “script writing”
• Generating placeholder content, lorem ipsum, test fixtures
• Writing basic SQL queries
• Explaining what a block of legacy code does (AI reads it faster than a human)

None of these were large bills individually, but they added up. Projects that used to have a “miscellaneous dev tasks” line item now have a smaller one or none at all.

What this means for your scoping

If a project was priced in 2022 based on 80 hours of work, it probably isn’t 80 hours of work in 2026. But it also isn’t 20 hours — because the time saved on routine work is partly offset by the increase in review and judgment. A reasonable rule of thumb: the same project might take 50-60% as long, not 25%.

Anyone who tells you “AI will make this 10x cheaper” is selling something. Anyone who tells you “AI doesn’t affect pricing” is ignoring reality. The honest answer is that some parts of software work are genuinely faster, some are the same, and your bills should reflect the actual breakdown — not a flat hourly rate that pretends nothing has changed.

What to ask your developer

When you’re scoping a project, two questions are worth asking:

1. “Where in this project is AI going to save time, and where isn’t it?”
2. “How are you factoring that into the estimate?”

A thoughtful developer will have a real answer. Something like “the boilerplate and the documentation will be faster, but the integration with your existing inventory system is still the hard part and most of the time will go there.” That’s a good sign. It means they’re paying attention to what’s changed and charging you accordingly.

If the answer is “we don’t use AI” or “nothing has changed,” be a little skeptical. The tools work. The developers who use them are honest about the time savings. You should benefit from that, and the ones who don’t pass the benefit along eventually lose work to the ones who do.
