How to Manage a Software Development Agency (And Not Get Burned)

TechaizenJuly 10, 20267 min read

Most agency engagements that go wrong do so for predictable reasons. Here's how to set up the relationship for success — and the warning signs that something is going off track.

Hiring a software development agency is not the same as hiring employees — and treating it as if it were is one of the most reliable ways to end up with a difficult engagement. The skills that make you a good people manager don't automatically transfer to agency management, and the expectations that work for an in-house team don't automatically fit an external one.

This guide is for founders and product leads who are about to engage an agency, or who are mid-engagement and sense that something isn't working as well as it should.

Why Agency Engagements Go Wrong

Before the practices, the failure modes. Most agency engagements that go wrong do so for one of a small number of reasons.

The brief was underspecified. The agency built what they understood you to want, which turned out to be different from what you actually wanted. This is not always the agency's fault — ambiguous briefs produce ambiguous outputs. The client who says "you should have asked more questions" and the agency that says "you should have told us more clearly" are both partially right, and both partially responsible.

Review cycles were too long. Feedback that arrives at the end of a two-week sprint doesn't prevent two weeks of work going in the wrong direction. Agencies that aren't corrected frequently build momentum in the wrong direction — because that's the only direction available to them.

The relationship was treated as transactional. Agencies that feel like they're executing tasks rather than solving problems tend to stop raising concerns. The engineer who notices a design decision that will cause problems later says so when they feel like a trusted partner. They stay quiet when they feel like a contractor on a fixed-price job.

Expectations about communication weren't set. How often will there be updates? Who has decision authority on the client side? What's the process for scope changes? Teams that don't establish these conventions spend a disproportionate amount of time on meta-communication rather than the work itself.

Setting Up the Engagement

The first two weeks of an agency engagement are the highest-leverage period for everything that follows.

Agree on the definition of done. Before a line of code is written, establish what "complete" means for the first deliverable. What are the acceptance criteria? How will testing be handled? Who signs off? This sounds obvious, but many engagements skip it — and then discover that "done" means different things to different parties.

Establish communication conventions. Decide: how often will you have a synchronous call? What's the primary channel for async updates? How will blockers be escalated? Who is the single point of contact on the agency side, and who is it on yours? Two points of contact on each side with no defined hierarchy for decisions is a recipe for conflicting instructions.

Run the agency through a starter task. Before committing the full scope to a new agency, give them something meaningful but bounded — a single feature, a defined module, a clear deliverable. Evaluate their output and their process: how did they communicate during the work, how did they handle an ambiguity or blocker, what did the code look like at the end? This tells you far more than the sales process did.

Be explicit about your involvement level. Some agencies work well with a client who is deeply involved in product decisions throughout the build. Others are set up for more independent delivery and perform better with a clearly defined brief and a review at the end of each cycle. Know which one you're working with and set expectations accordingly.

Staying on Track During the Build

Review early and often. The single most effective thing a client can do to improve agency output is provide frequent, specific feedback. Not "I don't like it" — but "the flow from step 2 to step 3 doesn't match what we discussed: the user should be able to skip step 2 if they've already provided their payment details." Specific feedback enables fast correction. Vague feedback generates a second round of guessing.

Create a shared space for open questions. Agencies accumulate questions during development. If those questions have nowhere to go — if the client isn't responsive or the channel isn't clear — they get answered by assumption. Create a shared backlog for open questions, review it regularly, and make sure the agency knows they should surface ambiguity rather than resolve it silently.

Separate feedback on progress from feedback on product. A sprint review that conflates "is the code doing what was specified" with "does the specified thing solve the right problem" leads to confused action. Progress feedback tells the agency whether they've built what was asked. Product feedback tells you whether what you asked for is actually what you need. Both matter, but they require different responses.

Watch for the signs of scope drift. Scope grows in small increments that each feel reasonable. An agency that never pushes back on scope additions is either not tracking them or building a liability for a later conversation. An agency that's clear about what's in scope and what isn't — and what the implications are for timeline and cost when scope changes — is doing you a favour.

Warning Signs Something Is Off Track

You're not getting regular, unprompted updates. A well-run engagement surfaces progress, concerns, and blockers before the client asks for them. If you're always chasing status, the communication structure isn't working.

Demos don't match what was discussed. A meaningful gap between what was agreed and what's shown in a review is worth investigating. Occasional misalignment is normal. Consistent misalignment suggests the brief, the feedback loops, or the team's understanding of the requirements has a systemic problem.

Technical concerns aren't being raised. Good engineers notice potential problems before they materialise. If an agency never surfaces a technical concern or alternative approach — if every sprint is frictionless and affirmative — either the work is very well-specified, or the agency isn't engaged enough to identify problems.

The timeline keeps slipping without explanation. Timeline changes happen in software development. They're acceptable when explained and flagged early. Timeline slippage that's only revealed at the sprint review, without early warning, indicates a planning or communication problem.

When Things Go Wrong

If an engagement is not going well, name it directly rather than hoping it resolves itself. A specific conversation about what isn't working — with examples, not just an overall assessment — gives the agency the opportunity to respond and adjust. Agencies that can't respond constructively to that kind of direct feedback are agencies to reconsider; agencies that can respond are often worth keeping.

The worst outcome is to continue an engagement that isn't working because the conversation about what isn't working feels uncomfortable. The cost is time, money, and a product that isn't what it needs to be.

If you're looking for a development partner for a new product or a project that's going off track, get in touch. We're used to being transparent about scope, timelines, and concerns — it's how engagements end up going well.

We build the things we write about.
