WooCommerce Review from Amanda Viviano
We hired Qolos to build our local florist shop's website on WordPress and WooCommerce, and we couldn't be happier with the results. From the start, they took the time to understand our business and created a site that's not only beautiful but easy for our customers to browse and shop.
The WooCommerce setup was seamless, our online ordering works exactly the way we needed it to. But what really sets Qolos apart is their ongoing monthly maintenance. We never have to worry about updates, security, or technical issues because they stay on top of everything. Any time we've had a question or a small change request, they've been responsive and professional.
As a small local business, it means a lot to work with a team that genuinely cares about keeping our site running smoothly. Qolos has been a true partner, not just a vendor. Highly recommend them to any local business looking for reliable web design and maintenance!

Web Development Review from Sanjay Singh
I kept getting negative reviews about my app for technical glitches, heating issues, functionality, loading time, crashing, and more bugs. So, I reached out to QOLOS after going through 2-3 renowned review platforms. I explained my app issue to the team, and they did tremendous work with their mobile testing solutions. Also, I wanted to build a website for my app. They created a feature-rich and seamless website.

Shopify Review from Sarah Nesheim
Working with QOLOS was the best decision I have made in regards to scaling my business. They are professional, so creative, they communicate every step of the way and their pricing is fair for the highest quality work. The designer of our logo and website did it well and I am so impressed and proud of the final product! the designer listened and knew exactly what I wanted which made the process so simple. Seriously could not recommend QOLOS more!

Alice Boscaro's Review Sourced from Google
As part of the company’s administrative department, I’ve had the opportunity to work closely with Lasting Dynamics, and I can say the experience has been very positive. From the very beginning, their team demonstrated great professionalism, strong organization, and special attention to detail, which made the internal management of our project much easier.
Communication was clear and consistent—which for me is essential—and they were always willing to adapt to our needs. Beyond their technical quality, I especially value their ability to provide practical and efficient solutions that bring real value to the business.
I consider Lasting Dynamics to be a reliable, innovative, and committed company, and I would not hesitate to work with them again on future projects.

It has been 2 years now since I started my first international career as a UI/UX designer, and I am still amazed every day. The people I work with are truly inspiring, and the products they create reflect the same level of quality. Being part of this environment has been a meaningful experience where I’ve learned and grown alongside talented individuals.

I bought a variety pack of protein bites from the Made in Chicago Market. They taste really good and have a nice amount of protein. The chocolate chip cookie dough and fudge brownie are my favorites. The serving size is 3 seperate bites, but I was satisfied after 2. They are a great snack! If I’m just a little hungry and want something a tad sweet it’ll be great to just grab one from the fridge.

Menura Dolage
Review from Google
5.0★
Menura Dolage's Review Sourced from Google
Creative Software – Colombo 3 is a place I’ve come to know quite well, and overall, it absolutely lives up to expectations. I would recommend it to both organizations and individuals looking for reliable IT services, but also as a great workplace environment.
Getting in requires going through security and receiving a clearance card, so access is controlled and feels secure. Once inside, the environment is clean, well-maintained, and surprisingly comfortable for a corporate setting. It’s not overly crowded either, except maybe around lunchtime in the cafeteria.
What really stands out here is the workplace culture and facilities. The people are easily the best part; friendly, supportive, and great to work with. On top of that, the office has a lot of perks like free coffee, a pool table, PlayStation 5, foosball, board games, and even a gym with showers. It creates a relaxed and enjoyable atmosphere that makes day-to-day work much more pleasant.
The only real downside is parking. The underground car park isn’t sufficient for everyone, so there’s an additional parking area about 100 meters away, which can be a bit inconvenient.
Overall, it’s a clean, secure, and well-managed place with a cozy and positive vibe. It’s been a great experience for me, especially as an intern, and it’s somewhere I’d gladly continue being part of.

One of Sri Lanka's original start ups, and the first Scandinavian investment in the local software scene. With a cadre of over 700 software engineers, tie ups with major universities on software skills and technology enhancement, Creative is helmed and run by an easy going set of people bent on re shaping the software field and giving back to the nation in the form of various CSR projects.

What are the most requested services of custom software development firms?
The most requested services from custom software development firms are almost entirely AI-based products, delivered primarily through web application development, mobile development, AI agent development, and legacy system refactoring. UX/UI design, cloud infrastructure, DevOps, and QA automation are typically not sold as standalone services; instead, they are embedded within each of these project types.
As reported by Diffco, year-over-year trends show a prevailing shift: AI agent development has grown from a niche request into a significant share of overall volume, while demand for legacy system refactoring continues to rise as clients seek to prepare their existing systems to support AI capabilities.

How much does a software development company charge for its services?
The cost of software development services depends on the tech stack, core functions and features, compliance and integration requirements, project complexity, and engagement model.
Developers in North America will charge more than those in Europe or Asia, so you should budget for $120-$200/hr for American developers and $25-$150/hr for a software developer from Asia or Europe.
Custom software development cost estimates based on project complexity:
Project type
Cost
Simple App / MVP (minimal features)
$50,000-$150,000
Medium Complexity (CRM, marketplace sites)
$150,000-$500,000
Large Enterprise Software
$500,000-$2,000,000+
Examples (ERP/Complex Platforms)
$200,000 and up
How do I determine if a global company is the right size for my project?
To determine if a global software development agency is the right size for your project, match project complexity and scale to company capacity.
Choose a large/global agency with 1000+ staff, if your project:
Is complex or enterprise-grade, includes multiple software solutions, integrations, and compliance
Needs 24/7 support, multi-time-zone delivery, or long-term maintenance
Large software development companies reduce delivery risk for complex programs but typically charge higher rates and use more structured processes.
Choose a small or mid-size agency with 10-200 staff if your project:
Is an MVP or mid-scale build
Requires speed, flexibility, and direct access to senior talent
Has a tighter budget and well-defined scope
Who owns the Intellectual Property (IP) and source code at the end of the project?
In most software development projects, the client owns the Intellectual Property (IP) and source code upon completion of the engagement, unless the contract explicitly states otherwise. Standard practice dictates that the ownership of the source code, documentation, design elements, and custom deliverables belongs to the client upon full payment. Contracts typically use "work made for hire" or an IP assignment clause to formalize this.
Third-party or open-source components, however, are not owned by the client. Instead, they are used under their respective licenses. Some agencies retain ownership of pre-existing frameworks or reusable tools and grant the client a license to use them. You should also know that IP ownership is not automatic. To avoid disputes, ensure the contract clearly states full IP and source-code ownership transfers to you upon payment, with no usage limitations.
What tools and frameworks do software developers use?
They use various tools and frameworks, depending on the type of digital product they’re building. But the most common include:
How many hours of integration work do software development projects typically entail?
Software development projects require between 20 and 500 hours of integration work per system, depending on complexity.
Integration type
Typical effort
Simple services (email, SMS, analytics, payments)
20 to 80 hours each
CRM and auth/SSO
40 to 120 hours each
ERP, healthcare (HL7/FHIR), banking/KYC
150 to 500 hours each
As per Diffco, the number of integrations also scales with project size: small builds typically involve 2–4 integrations, mid-sized builds 5–10, and large enterprise platforms 10–25 or more. The software development company also discloses that integrations are inventoried and priced individually rather than folded into a single project total, allowing clients to phase the more costly integrations as needed.
