TL;DR This article guides you through the process of working effectively with a software house. It explains what information you should prepare before starting, how technical documentation supports estimation, and why project management systems are essential for smooth communication. You’ll also learn about project implementation stages, the difference between fixed price and time & materials models, typical pricing ranges for different project types, and the scope of warranty and post-implementation support. The main takeaway: successful cooperation requires clear communication, transparency, and mutual involvement from day one.
You’re facing the decision of hiring a software house — and you’re not sure what to expect, what to prepare, or what to ask for. Here’s a practical guide based on our experience working with clients across e-commerce, B2B, and custom web application projects. The goal is to help you walk into the first conversation prepared, and to understand exactly how the process works from inquiry to launch.
At the beginning of the cooperation
Understanding how a software house works before you sign anything makes the whole project go better. When both sides are clear on the process, the scope, and the expectations, there are no surprises and no disappointments.
To estimate your project accurately — in time and in cost — we need to understand your business goals, your industry, and what you’re trying to build. You need to understand how we work and what the collaboration will look like day-to-day. That’s why the first step is always a conversation: a phone call, a video call, or if you prefer, an exchange of emails. There’s no wrong format.
What matters is that both sides leave that first meeting aligned on what the project is, what it isn’t, and what happens next.
What are we going to ask you about before we start to estimate the project?
We know that clients often struggle to articulate all requirements upfront — that’s normal, and it’s why we ask questions. The more specific your answers, the more accurate our estimate.
For an existing website, we’ll ask for the URL, hosting provider, technology stack, and target audience. For a new project, we’ll ask you to describe the idea in two or three sentences, name the competition, and identify the goal you want the software to achieve.
A few things that matter most:
Desired functionality. What should the software do? What should it not do? If you’re building an online store, we’ll ask about products, traffic expectations, and integrations. If you’re building a product configurator, we’ll ask about the configuration logic, the variables, and how pricing is calculated.
Timeline. When do you need the project to go live? This has a direct impact on cost. Rush timelines require additional resources and tighter scheduling. More flexible timelines allow us to plan work more efficiently and keep costs lower.
Budget. If you know your budget, share it. This isn’t a negotiating tactic — it’s the most direct way to find the right solution. A clear budget allows us to identify what’s achievable within that range and what might need to be phased or simplified.
As a general orientation for US clients: ongoing development work in the time & materials model starts at our standard hourly rates; larger fixed-scope projects such as a custom e-commerce implementation or a product configurator typically start from $15,000–$25,000 depending on complexity. More complex 3D configurators or full e-commerce builds with custom integrations are higher. For a detailed breakdown, see our article How much does custom software cost?
Creating technical documentation
Technical documentation is a universal document that you can use to ask different software houses to Technical documentation is a written specification of what the software should do. It’s the document you can take to any software house and ask for an estimate — and get comparable, apples-to-apples quotes in return.
For simple projects, full documentation isn’t always necessary. For complex or large-scale projects — multi-module e-commerce platforms, custom configurators, B2B portals — it is essential. If you don’t have documentation when you come to us, creating it becomes the first stage of the project.
A standard technical document covers:
- Recommended technologies
- Elements on each page and how they behave
- Integrations with third-party systems (CRM, ERP, payment gateways, shipping providers)
- User roles and permission levels (admin, logged-in user, guest)
- Allowed and restricted actions at each stage
- Notifications and how they’re triggered
- Admin panel functions
- Navigation structure and user flow
We can also create wireframes and mockups as part of this stage — visual representations of key pages like the product page, cart, and checkout — so you can review the structure before development begins.
Project management system
One of the most important components in the project is mutual communication. There are many ways of haEvery project we work on is managed through a dedicated project management system. This is where all communication, task tracking, time reporting, and change requests happen. It’s the single source of truth for both sides.
The practical benefits for you as a client:
All arrangements are in one place — no digging through email threads to find what was agreed three weeks ago. Tasks have clear statuses: awaiting assignment, in progress, done, requires additional information from you. You can set priorities on tasks that are critical to you. You can access the system 24/7 and submit requests at any time. And for projects billed in the time & materials model, you can see exactly how many hours have been spent on every task, reported with 15-minute accuracy.
This transparency is deliberate. You should never have to ask us “where are we?” — the answer should always be visible in the system.
Project implementation stages
Whether you have technical documentation or not, project implementation stages are more or less the same:
- Interview about your business goals, the company and industry
- Appraisal of the project
after the analytical process of creating technical documentation,
based on the delivered technical documentation.
- Software development and tests
- Website implementation
- Post-implementation service
What do you have an insight into and how can you report changes?
Each and every detail of important information can be found in the project management system, in Throughout the project and after launch, you have full access to the project management system. At any moment you can see:
- All tasks and change requests, both active and archived
- Time logged on each task, with 15-minute granularity
- Current usage of paid work hours (for time & materials projects)
- Task status for every item in the backlog
To order a change or report a problem, you create a new thread in the system. We respond and assign the task as quickly as possible. This applies both during active development and for live sites under ongoing support.
Fixed price vs time&materials – which one to choose?
The right model depends on what you’re building and how well-defined the scope is.
Fixed price is appropriate for projects with a clearly defined scope — typically larger builds like a full e-commerce implementation, a corporate website, or a product configurator with agreed specifications. The price is set upfront based on the documented scope. You know the total cost before work begins. Changes to scope outside the original agreement are handled as separate change orders.
Time & materials is appropriate for ongoing work — smaller feature additions, updates, bug fixes, and iterative development where the scope is not fully defined in advance. You pay for the actual time spent, reported with 15-minute accuracy. There are two payment structures available: monthly billing based on time records, or advance programming packages valid for 12 months from purchase.
For most clients, the pattern looks like this: a larger project starts as a fixed-price engagement. Once the project is live, ongoing maintenance and new features shift to a time & materials arrangement.
For a detailed comparison of both models, see our article Fixed price vs. time & materials — pricing models in software houses.

It may include a guaranteed response to any problems, unlimited support regarding the use of your application, and the ability to add new features. If you decide to utilize our server infrastructure, we will provide you with hosting space, and also include the SSL certificate, free for the first year.
How to cooperate with a software house – final thoughts
A successful software project is a joint effort. The more clearly you can communicate your goals, constraints, and feedback, the better the output. At the same time, a good software house should make this easy — by asking the right questions, keeping you informed at every stage, and giving you direct visibility into what’s being built and how much it costs.
The things to look for when evaluating any software house: they ask specific questions before estimating, not after; they use a project management system that you have direct access to; they report time transparently if billing by the hour; and they stand behind their work with a clear warranty.

FAQ
1. What is the difference between fixed price and time & materials?
In a fixed price model, the total cost is agreed upfront based on a defined scope of work. The price doesn’t change unless the scope changes. In a time & materials model, you pay for the actual hours spent on your project, reported with 15-minute accuracy. Fixed price works well for large, well-specified projects like a full e-commerce build. Time & materials works better for ongoing work, iterative development, or projects where the scope is likely to evolve.
2. How do I prepare for my first meeting with a software house?
You don’t need to have everything figured out — that’s what the meeting is for. It helps to come with a basic description of what you want to build (two or three sentences), a rough sense of your budget, and your preferred launch timeline. If you have an existing website, have the URL ready. If you’ve looked at competitors whose functionality you want to replicate, note those too. The more context you can provide, the more accurate the estimate you’ll receive.
3. What is technical documentation and do I need it?
Technical documentation is a written specification describing how the software should work — what pages exist, what each element does, how users interact with the system, and what integrations are required. For simple projects it’s often not necessary upfront. For complex projects — configurators, multi-role B2B portals, large e-commerce platforms — it’s essential for getting an accurate estimate and aligning both sides before development begins. If you don’t have documentation, creating it is typically the first paid stage of the project.
4. How can I track the progress of my project?
Through the project management system we use for every engagement. You have 24/7 access to all tasks, their statuses, time logged on each item, and the overall resource usage for time & materials projects. You don’t need to email us to ask where things stand — the system always reflects the current state of the project.
5. What does a software house warranty cover?
Our warranty covers bugs and unexpected behavior in the code we delivered — anything that doesn’t work as specified in the agreed scope. It includes guaranteed response times for reported problems and unlimited support for questions about using the application. It does not cover new features or changes to the original scope, which are handled under a separate agreement. If you use our hosting infrastructure, server monitoring and a first-year SSL certificate are also included.
6. How long does a typical web project take?
It depends on complexity. A standard e-commerce store or a corporate website with custom functionality typically takes 6 to 12 weeks from the start of development to launch. A product configurator project — particularly if it involves 3D visualization or complex pricing logic — typically takes 10 to 20 weeks. These timelines assume that client feedback is available at agreed review points. Delays in feedback or significant scope changes during development extend the timeline accordingly.
