Technical failures can happen in software development, but if your client approved a feature list three months ago, and they're currently upset it doesn't have a feature that was never in the original spec, then you have a documentation failure.
In this guide, I'll show you why you need a scope of work statement, and what should be in your document to avoid situations like this with clients. We’ll also share a template that you can edit for your clients.
A scope of work is a technical contract that defines what you're building, how you're building it, and when the project is complete.
It documents every feature with enough detail that both you and your client understand what every term used for the project means. It helps you separate one-time development work from ongoing services you may offer, like hosting, maintenance, and support. It also establishes how bugs are handled versus feature requests, and what triggers additional billing.
Software projects are easily susceptible to slow and unprofitable work if you don't clearly draw your boundaries beforehand. Let's see how that can happen:
Feature creep is when your client asks for extra features to the software than what was initially agreed on without additional pay.
Asking for extra features isn't bad.
Feature ideas come as you work on the software. What's wrong is if they expect you to work on these extra requests for free.
For instance, let's say your client asks for a date flier for the user list. They want their users to click a dropdown and select a date range.
They believe it's simple, but building those filters will require work throughout your entire application.
It takes time. Your scope of work prevents this by listing every feature with its technical specification. Rather than write user management only, write everything that will happen under User management, for example:
This lets them see the technicalities behind each feature requests that has been discussed, and if they have extra requests, you can bill them separately for that.
Your client paid for your services, but they don't necessarily know what goes on in the background, so they create their own assumption of what a feature is, and what it entails, and you end up in situations like this:

This Reddit user now has to deal with a client who's not sure of what they wanted and piles new features and changes on the developer mid-project.
That happened because they didn't document technical details beforehand.
Your client probably has an assumption on what the app will look like before the project even starts, but the problem is that their specification may not match that assumption.
Your scope of work solves this by including acceptance criteria for every feature. For instance, for payment processing, you may document that:
When you deliver exactly what's documented, clients can't claim that you didn't include all the features you discussed.
Let's look at this scenario:
Your client receives your development quote and signs the contract.
You build and deliver the application, but they still expect you to offer ongoing maintenance service that wasn't agreed on initially.
This happens because software development can blur into software operations. If you don't set your boundaries early, your clients will see the ongoing work as part of the original service they purchased.
Your scope of work separates one-time work from recurring services. It also documents what the project does not include.
Some clients may disguise new feature requests as bug fixes. They’ll say the dashboard is confusing when they actually want a new layout.
Your scope of work defines what qualifies as a bug, which are features documented in the scope that don't work as specified, like application crashes or unhandled errors, or security vulnerabilities.
You can also define the warranty period in the document. For example, if you’ll only offer thirty days of bug fixes after launch, state it.
You can build your scope of work with these nine components:
Start by stating why the software is being built and what problem it is intended to solve. This anchors every technical decision that follows.
This section should briefly outline:
Don't talk about the features in this section. It's about the project’s intent, over its implementation.
Once the purpose is clear, define what the software will do from a user and system perspective. This includes the core functionality that you need to meet the stated objectives, like the:
You should write these requirements out in a clear, non-technical language, so your client understands them.
You should also clarify how the software is expected to perform and operate.
This includes:
There's little to no room for assumptions when you’ve made everything clear about performance, scalability, or security.
Clearly identify what you will deliver to the client during and after the project comes to an end. You should do this for every feature you’ll deliver, so the client knows what to expect and you can focus on doing your real work.
For instance, the deliverables for User Authentication can be:
Pro Tip: Define your deliverables clearly. Add the format, timing, and dependency to avoid any ambiguities.
Break your development process into phases with clear deliverables. Let the client know what they’ll get from every phase of the project.
For example, add that:
Phase 1: Foundation will take the first 1-2 weeks, including:
Phase 2: Core Features (Weeks 3-5)
Phase 3: Polish & Testing (Week 6)
Phase 4: Deployment (Week 7)
For each major deliverable, include how it will be reviewed and approved. Acceptance criteria provide an objective basis for determining whether the work has been completed satisfactorily.
So structure your acceptance criteria to address:
This section protects you from accidentally signing up to run the client’s software forever. It helps you treat development as the work required to build, launch, and stabilize the application, and nothing more.
Make a list of what's included in the development and what’s not. The moment the app is live, anything that involves recurring effort, recurring cost, or ongoing responsibility needs to sit outside the core scope.
Be explicit about this boundary because clients can naturally assume you’ll handle hosting and updates for them after the app goes live.
This section will help you slow things down on purpose. Clients will ask for changes mid-build (which is normal), but you need a process that forces those requests to be deliberate, priced, and approved.
Make every change start with a written request so you can assess the impact before touching the code.
For example, if you use ManyRequests, clients can submit change requests through the request feature instead of mentioning ideas in calls, emails, or chats.

ManyRequests gives you a single platform to review every request the client sends in, estimate time and cost, and decide whether it fits the current phase. Once a request is submitted, you can respond with a clear estimate and create tasks from that single request.
Your terms should be clear in your scope of work. For example:
Requesting Changes:
You should also discuss the pricing.
Change Request Pricing:
Pro Tip: Wait for explicit approval from the client, after you estimate time and cost, before you start work.
When writing your scope, define what you’ll fix for free, or what would cost extra. A bug means the software does not behave the way the scope says it should, but if your client decides to change their mind on a feature, then that's not a bug, and they can pay for that.
Set a short, defined warranty window and stick to it. You should also fix real defects during that period, then switch to billable work once it ends. This tells your clients to respect the boundary between fixing mistakes and adding new ideas.
Here's how to customize our free software development scope statement template to fit your agency's needs:
Scope of work document protects you from an endless feature creep that could stretch the project more than agreed on. If you don't set your boundaries right with your client, they’ll pile on extra works until you lose track of what you discussed in the beginning.
This document is a reference point so you can avoid this. You can also further improve your project boundaries with ManyRequests. With our platform, you can bill for extra work, take client's requests, manage your team and the task, and sell your productized services, without leaving the platform. If this interests you, we offer a 14 days free trial to show you how it works.
Download the free software development scope of work template and adapt it for your next project. Document every feature with technical specifications, define clear acceptance criteria, and separate development from ongoing services before writing any code.
This prevents scope creep, eliminates arguments about what "done" means, and protects your profitability—so you can focus on building software instead of managing client expectations through endless email threads.
