Your board or lead investor has asked why you're still paying a dev agency when AI can write code. For most teams the honest answer is that you should renegotiate or shrink the contract, not replace the agency outright. In our view, AI tools change how routine code gets produced; whether that makes it cheaper isn't measured yet. They don't make owning a running system any cheaper, and the agency contract usually covers both.
This guide splits the work in a typical agency contract into what AI can absorb and what still needs a named human, then walks through four renewal options, the questions to ask the agency, and the terms worth putting on the table. It sits within our wider guide to Software development engagement models: staff augmentation, dedicated teams, nearshore and offshore.
Why boards ask this now
In June 2026, Harvard Business Review published Abhinav Agrawal's "AI Is Rewriting the Economics of Outsourcing". Its summary describes AI as automating "many routine, rules-based tasks that companies once sent offshore for labor savings." It's a fair description of why the question is live. In our judgment, some of what agencies bill hourly is work AI tools can help with. Whether that means your agency's bill should fall, and by how much, is a separate question that no one has a neutral number for. Treat everything below that isn't a quoted source as our judgment.
What AI can absorb from an agency contract, and what it cannot
Split the contract by type of work, not by headcount. This table is our judgment, not a measured result.
| Work type | AI-exposed? | Who must own it |
|---|---|---|
| CRUD endpoints and scaffolding | Yes | A reviewer who reads every diff |
| Tests and documentation | Yes | A reviewer who checks they test the right thing |
| Routine migrations and upgrades | Yes | An engineer who owns the rollback plan |
| Architecture decisions | Partly, as a sounding board | A named senior engineer |
| Domain logic | Weakly | Someone who understands your business rules |
| Security review | Weakly | A named senior engineer |
| On-call and incident response | No | A person who gets paged |
| Release ownership | No | One accountable person |
The bottom half of that table is where agencies earn their money, and it's the half a coding assistant mostly doesn't replace. The top half is where you have bargaining power in a renewal.
Two sources support the caution. The Stack Overflow 2025 Developer Survey found that "more developers actively distrust the accuracy of AI tools (46%) than trust it (33%)", and that 66% name "AI solutions that are almost right, but not quite" as their top frustration. Almost-right code needs a reviewer, and a reviewer is a salary or an invoice line. The DORA 2025 report puts it this way: "AI's primary role is as an amplifier, magnifying an organization's existing strengths and weaknesses." Our reading: an agency with weak review habits may ship weak code faster.
What the measured evidence says about AI speed-ups
The tempting move is to demand a percentage cut: if AI makes developers X% faster, hours should fall X%. The measured evidence doesn't give you an X.
METR's July 2025 randomised study gave 16 experienced developers 246 issues on repositories with over a million lines of code. METR reported that with AI tools "they take 19% longer than without". Developers had predicted a 24% speed-up. METR itself marks that result as out of date, calling it "a snapshot of early-2025 AI capabilities in one relevant setting".
Its February 2026 follow-up covered 57 developers, 143 repositories and over 800 tasks. METR wrote that "we believe it is likely that developers are more sped up from AI tools now", and also wrote that "our data is only very weak evidence for the size of this increase."
So the vendor-neutral answer is that there isn't one. Don't accept a number from the agency or from the board. Ask the agency for its own measured cycle times on your codebase, before and after it adopted AI tools.
Four options for the renewal
1. Keep the agency, renegotiate
This is the default for most teams. You keep the people who know the system and change the terms: an explicit clause on how the agency uses AI tools, a fixed seat count or rate card review, and either a capped fixed scope or an outcome-based component for routine work. If you're weighing the pricing mechanics, our guide to fixed price against time and materials covers hybrid caps and the minimum-hours trap. The terms to put on the table are further down.
2. Cut scope
Move the routine work (the top half of the table) to your own people with AI tools, and keep the agency on the hard part: architecture, security, release ownership. This only works if someone in-house can review AI output. If nobody can, you've moved the risk, not the cost.
3. Move to a smaller senior team
Replace a large blended team with a few senior engineers who use AI tools and carry the ownership work. In our view, fewer people at a higher rate each can keep the same accountability. Our guide to moving agency work in-house covers the cooperative exit, and the seat-versus-hire arithmetic is in the next-step link below.
4. Replace entirely
This holds in a narrow case: the codebase is stable and well documented, a named owner exists on your side, and the work is mostly maintenance. It fails when nobody is on call, when knowledge lives in the agency's heads rather than in the repository, or when the system is still changing fast. In our view, "replace entirely" is the least likely outcome of an honest review, and the one boards ask about first.
What to ask your agency before you decide
Use this as a checklist in the renewal meeting.
- How do your engineers use AI tools on our codebase, and which tools?
- What review gates stand between AI-generated code and production?
- Who signs off merges, and are they a named senior engineer?
- What is the measured cycle time on our tickets before and after you adopted AI tools?
- Who carries liability if AI-generated code infringes a licence or introduces a defect?
- Which of our tickets would you now estimate lower, and why?
- What would you stop billing hourly for if we moved it to a fixed price?
Vague answers to the first three tell you more than any discount does.
How to renegotiate: terms to put on the table
These are our suggestions, not market norms. We don't have sourced data on what agencies typically concede.
- Move routine work from a rate card to a fixed price or a capped scope, and keep the rate card for open-ended work.
- Reduce seats where the agency can show the work shrank, and ask to see the evidence.
- Add a clause that requires disclosure of AI tools used on your code, and a review gate on AI-generated changes.
- Remove any minimum-hours floor so you can scale down without a penalty.
- Shorten the notice period, so a smaller scope doesn't lock you in for another year.
- Write handover obligations into the contract: documentation, environment access, and a transition period at a defined rate.
- Confirm in writing that IP in all work product, including AI-assisted work, is assigned to you.
Get a lawyer to review the final wording. Handover and IP terms are the ones that cost the most when they're missing.
Handover and IP risk if you drop the vendor
The risk in cutting or replacing an agency isn't the code, it's the knowledge around it: deploy steps, credentials, undocumented decisions. If the exit is friendly, ask for a documented transition and a paid overlap. If the relationship has already soured, our guide to taking over a codebase when the agency fails covers the practical sequence. Either way, check before the notice period starts that you hold the repositories, the cloud accounts and the domain registrations yourself.
What this means for your agency renewal
This section is judgment, not sourced fact. Before the renewal date, decide which of the four options you're really choosing between. For most buyers it's renegotiate or shrink. Take the table above to the agency and ask which rows they'd bill differently today. Insist on the measured cycle time data, because the evidence we have doesn't support any particular discount. If you plan to bring routine work in-house, price the AI seats against the review time they create, not against the agency's hourly rate alone. And don't cut a person who holds on-call or release ownership until a named replacement has done a release.
For the cost side of that decision, read what AI coding seats cost against a senior hire.
Moving to a smaller senior team through HighCircl
If you choose the smaller senior team, or want a senior engineer to own the work you're keeping, senior engineers through HighCircl is one route. HighCircl sends a shortlist of 3-5 engineers within 72 hours, from seven EU countries. Four vetting stages run by senior engineers, and about 1 in 10 applicants pass. There's no minimum hour commitment, subscription or recruitment fee. Rates run EUR 45-105/hr ($50-115/hr), with a capped 20% margin on top of what the engineer earns. If an engagement isn't working, replacement carries no additional recruitment cost. Keep your agency where it's strong.
FAQ
Can AI replace a software development agency?
For most companies, not entirely. AI can take over a share of routine coding, but on-call, release ownership, architecture and security review still need accountable people. Entire replacement holds only for a stable, well-documented codebase with an internal owner.
Should I cut my outsourced developers because of AI?
Cut by type of work, not by headcount. Routine, reviewable work is exposed. Anyone holding on-call or release ownership isn't. The measured evidence from METR doesn't support a specific percentage cut, so ask for data on your own codebase before deciding.
How do I renegotiate a dev agency contract when AI makes coding cheaper?
Ask how the agency uses AI tools, ask for measured cycle times, and move routine work to a fixed price or capped scope. Remove minimum-hours floors and shorten notice periods. Treat any discount figure without data as a negotiating position.
Is a fixed-price contract better when the agency uses AI?
In our view, often, for well-defined routine work, because the agency can carry the speed-up risk and you get a known cost. For open-ended work, fixed price can lead to scope disputes. A hybrid with a cap is one compromise.
What do I do about code ownership if I leave the agency?
Confirm in the contract that IP in all work product is assigned to you, and that you hold the repositories, cloud accounts and domains. Check this before you give notice, not after.
