Hearing praises about WordPress is quite common, which could influence your decision to use this CMS for creating your website. If you’re leaning towards this, the next step is to find a trustworthy WordPress developer who fits your budget and schedule. This is a critical phase as it can significantly affect your entire project’s success.

When you begin your search, you’ll find two main options. You can either hire a freelancer or engage a WordPress development company.

Which is the superior choice? We can’t immediately guide you in one direction since both choices have their pros and cons. Ultimately, several factors may sway your final decision.

That’s why we’ve written this post, where we examine different aspects of the WordPress Agency vs Freelancer debate. We hope this comparison will provide a clearer understanding of what will serve your best interests in the long run. 

WordPress Development Company vs Freelancer: Factors to Consider Before Deciding 

Freelancers: Advantages 

Cost-Effective

Let’s start with something apparent: freelancers tend to charge less. There are a few reasons behind this.

Firstly, freelancers don’t have overhead costs like a WordPress development company. They don’t have HR managers, accountants, and other staff to pay. They also don’t have office rent, employee benefits, etc.

Secondly, the Internet has brought increased competition amongst independent professionals. Those who charge more may struggle to stay competitive. 

Greater Flexibility

Flexibility is another point favoring freelancers in the WordPress agency vs freelancer discussion. They strive to meet client needs and adapt to their requirements.

For instance, a WordPress agency has set operating hours. If an overseas client needs an urgent discussion over the weekend, it would likely have to wait until Monday morning.

On the other hand, freelancers are more willing to accommodate requests regardless of the day. 

Specialized Expertise

Depending on the complexity and scope of your project, this could be seen as an advantage or disadvantage. Typically, freelancers specialize in one particular area.

For example, they may be excellent front-end developers but might lack back-end knowledge. Therefore, if your task requires expertise in one specific area, a freelancer could be a good fit. 

Direct Communication and Trust

Another critical aspect of the WordPress Vs Freelancer debate is communication. With a WordPress agency, there’s a project manager acting as a go-between.

If the project manager lacks experience or efficiency, this indirect control and information exchange can slow down the process and cause bottlenecks. In comparison, you have a direct line of communication with a freelancer.

You can monitor their every move, ensuring deadlines are met and work is done to your satisfaction. This builds trust between you and the freelance WordPress developer, although it may consume more of your time that could be better spent managing your business. 

Freelancers: Disadvantages 

Limited Skillset

While a freelancer may excel in a particular area, they can’t be proficient in everything. As the saying goes, “Jack of all trades, master of none.”

So, if your project requires diverse skills such as front-end and back-end development, SEO, and server configuration simultaneously, we suggest opting for a WordPress development company that houses a variety of skilled professionals under one roof.

Inadequate Project Management Skills

Freelancers may fall short in the realm of project management, a point we can’t ignore in our WordPress agency vs freelancer comparison. In an attempt to maximize earnings, a freelancer might juggle multiple projects simultaneously.

If they fail to allocate appropriate time and effort to each task, it could negatively impact the final product’s quality or result in delays and missed deadlines. 

Project Completion Not Guaranteed

Working with freelancers carries inherent risk; you can never be entirely sure they will complete the task they’ve committed to. They could disappear without warning, leaving you in the lurch.

In most instances, there’s no legally binding document requiring freelancers to complete their assigned project or task, leaving clients powerless.

Imagine your hired freelancer abruptly quits. What’s your next step? You still need the work completed, prompting a potentially lengthy and laborious search for a replacement.

Even once you find a suitable substitute, they’ll need time to familiarize themselves with the previous freelancer’s work, resulting in further time and money wasted. 

Variable Quality

While many freelancers excel in their field, you may also encounter novices who lack familiarity with industry standards and best practices.

Consequently, the final product might not meet your expectations. This underscores one of the primary reasons to consider hiring a WordPress development company, which we’ll explore next. 

WordPress Development Company: Key Benefits 

Focused Project Attention and Effective Task Management

One significant advantage of partnering with a WordPress agency is the assurance that your project will receive undivided attention.

After placing your order, a dedicated manager will oversee your project from inception to completion, serving as a liaison between you and the development team while keeping you updated on progress and addressing any requests.

These project managers, experienced with numerous completed projects under their belts, adhere to proven workflows and management practices, providing a level of coordination few freelancers can match. The result? A high-quality final product, tailored to your specifications and delivered on schedule. 

Dependability

Another compelling reason to hire a WordPress development company is reliability.

Freelancers may leave you high and dry mid-project, forcing you to scramble for a replacement.

In contrast, established WordPress companies maintain a substantial pool of talented professionals equipped to handle complex projects. If a developer becomes unavailable, the management team can quickly replace them with another equally skilled professional.

This ensures uninterrupted development and timely project completion. 

Legal Protection

Business data is invaluable. The last thing you want is your sensitive information falling into the wrong hands. With freelancers, there’s no guarantee your project details won’t end up with competitors or cybercriminals, and you may have no legal recourse.

When you engage a WordPress development company, you sign a legally binding contract and non-disclosure agreement, protecting you from mid-project departures and data breaches. With white label WordPress development, you retain full ownership of the delivered code, without any mention of the development company. 

Broadly Skilled Talent Under One Roof

We’ve touched on this advantage in our WordPress agency vs freelancer discussion, but it bears repeating.

A company employs experts in various fields accustomed to team collaboration. This is particularly beneficial since businesses typically require comprehensive solutions. A website comprises front-end and back-end components and needs to be unique, user-friendly, and bug-free.

A web development company houses all the necessary WordPress expertise in one location, providing you with a visually appealing, thoroughly tested turn-key solution. You won’t need to scour the Internet for weeks searching for a suitable UX designer, then a front-end developer, then a back-end developer, and so on.

WordPress Development Company: Drawbacks 

High Costs

Indeed, it’s an undeniable fact that a WordPress development company will cost you more compared to a freelancer. This is primarily due to business overhead expenses such as employee salaries, benefits, multiple software licensing fees, and other compulsory outlays.

Furthermore, agencies typically prefer to hire experienced professionals who naturally command higher hourly rates compared to newcomers just starting their careers in WordPress development. 

Extended Response Times

Certain agencies have earned a reputation for subpar client service, often providing only one communication channel for clients. This can result in slower information exchange, leading to infuriating delays or miscommunications.

To Sum Up 

In conclusion, the decision to hire a freelancer or a WordPress development company for your custom WordPress web design largely depends on your specific needs and circumstances. While freelancers may offer a more cost-effective solution, they often come with potential drawbacks, such as unreliable delivery, variable quality, and lack of legal protections. 

On the other hand, a WordPress development company offers a broad range of skilled talent, focused project management, enhanced reliability, and legal safeguards, albeit at a higher cost. 

Remember to weigh these factors carefully to make the best choice for your custom WordPress web design or development project.

This post aims to guide you on how to pick an IT firm that will genuinely enhance your business value. The selection procedure is dual-pronged. It’s crucial to conduct thorough research before engaging in discussions with potential vendors on your list.

The need for software development services, especially web development outsourcing, has seen a consistent rise over the past few years. Last year it exponentially increased due to the ongoing pandemic crisis. Numerous businesses have transitioned a significant part of their operations online, embracing remote work.

This shift has resulted in a pressing demand for superior software development or IT services. Businesses are looking to automate most of their processes and hence, require expert web or software development support. Fortunately, this demand is met by a vast supply. Current data shows that there are 1.6 million software and web developers in the USA, equipped to tackle any job type (source: https://www.cyberstates.org/). 

A certain percentage of these are freelancers, but the majority are employed by IT firms. As per the same source, there are just under 560,000 tech business entities in the U.S. While this is a remarkable proposition, it poses a significant challenge. Many business owners struggle when choosing a trustworthy software development partner.

They need to navigate through countless questions. How to select an IT service provider who will create a product that meets all their expectations and serves them flawlessly for the foreseeable future? Don’t worry! We’ve compiled some insightful tips for those still undecided. Follow them, and hopefully, you’ll sidestep many common traps when selecting a web or software development agency. 

8 Guidelines on Choosing a Development Company That Suits You Best 

#1: Clearly Define Your Future Project’s Requirements

The initial step doesn’t involve any specific development company. It requires you to dedicate time and effort to clearly outline your needs and requirements. Write down a description of each feature you want the IT firm to develop, explaining why you need it and how it can benefit your customers or clients.

This will make the subsequent interviewing process simpler and save time and money. For instance, do you require a payment gateway integrated into your site? How do you envision the checkout page? Product pages? 

#2: Discover What Others Think About a Specific IT Service Provider

Ideally, you wouldn’t want to opt for an IT services firm that has just started. Look for a seasoned IT company with a strong track record of successful projects. One way to verify this is by checking their past clients’ testimonials.

Every software development company website showcases positive client reviews on its homepage. While we won’t question the legitimacy of these testimonials, vendors will undoubtedly highlight only positive feedback, so you’ll need to delve deeper to uncover the full picture. How?

Visit various specific websites where clients of web and software development companies can share their experiences. This feedback is meticulously reviewed by the administrators, ensuring its reliability. Some examples:

• Clutch
• Glassdoor

#3: Select a Development Company Based on Its Ranking Among Other Agencies

Consider the ranking of an IT company among other vendors

One way to guarantee you’re partnering with a reputable web or software development company is to check its ranking among competitors. You can do this by visiting one of many rating websites, such as:

• DesignRush
• Top IT Firms
• Top Ecommerce Development Companies
• Web Design Rankings
• TopDevelopers

IT companies are evaluated based on a wide array of criteria, including:

• Past projects
• Industry awards
• Team
• Client reviews

…and more.

#4: Review an IT Company’s Previous Work

Just as you would evaluate an architect’s past constructions before hiring them to build your home, similarly, it’s crucial to assess the previous projects of an IT company. Most reputable companies showcase their accomplished projects on their website.

Inspect these thoroughly. Do they align with your requirements? What sectors does the company cater to? For instance, a banking application will be vastly different from a training app.

#5: Assess the Quality and Information on Their Website

A professional and informative website is a good indicator of a competent IT company. If the website appears to be created using a basic website builder, it may raise doubts. Leading IT companies custom design their websites to ensure uniqueness, superior user experience, and quick load times.

Beyond aesthetics, the website should be informative and error-free. Opt for an IT company whose website is devoid of grammatical or spelling errors. Ensure that you can locate all the necessary client information. Look for responses to queries like ‘How is communication handled?’ or ‘How many experts are on the development team?’

Ideally, the website should also display pictures of all team members. 

#6: Choose a Development Company with Fair (not the Cheapest) Prices and Appropriate Pricing Models

Top software development firms don’t lure clients with low rates. They understand that crafting a quality product requires significant skill and effort to add real value to a business. While staying within budget is important, be wary of providers offering unusually low rates.

This is similar to purchasing a cheap car that constantly breaks down, costing you more in repairs than if you’d invested in a pricier vehicle.

Hence, our suggestion is to look for a web or software development partner with fair, not suspiciously low rates. Such an offer usually indicates the provider lacks experience, may deliver a poorly designed/coded app or website, and may take too long to complete the project.

Beyond rates, also consider the pricing models an IT company uses. For less complex or time-consuming projects, a flat rate might be the best choice. In such cases, opt for an IT development company that charges hourly rates.

#7: Understand an IT Company’s Data Protection Measures

In today’s digital age, any reliable web or software development service provider prioritizes personal data protection. The Internet is rife with freelancers and small IT firms with unclear data protection practices. They might disappear suddenly, leaving their clients uncertain about their valuable data.

Thus, when choosing a web development company, ensure they have a strong data protection system in place. A legally binding contract and a non-disclosure agreement are essential for any company in this field. 

#8: Ensure Transparency and Ease of Communication Regarding Project Progress

The commencement of a project, from discussing the initial requirements to its initiation, is merely the starting point. As the web or software development process unfolds, numerous aspects may arise. 

You may realize you require an additional business feature or wish to inquire about the current phase of the development work. The developers may stumble upon a more efficient resolution to your issue and need your input. The scenarios are endless.

Seamless and transparent communication is crucial in these situations. Opt for a web development firm that offers various methods for exchanging pertinent information (such as Skype, Slack, Email, Live Chat, etc.), starting with your preferred mode. 

A dedicated project manager should be available to promptly address your questions or update you about any modifications or concerns from the agency’s end.

Conclusion

Successfully selecting a web or software development company involves a multi-faceted approach. Firstly, it requires in-depth research into customer reviews and the company’s ranking among competitors.

Secondly, examining the company’s past projects and the quality of its own website can offer crucial insights into their capabilities and professionalism. 

Thirdly, the pricing structure should be considered carefully; while affordability is important, unusually low rates may indicate a lack of experience or quality. Lastly, the company’s data protection measures and their commitment to transparency and easy communication are crucial for a successful partnership.

By considering these factors, you can make an informed decision and select the right IT partner for your business.

In today’s world, a satellite can play the role of a primary network node, a telephone switch and a router-switch of a computer network, which is achieved by the interaction of satellite hardware not only with ground base stations, but also among themselves, forming direct space networks.

Modern satellites have four types of orbits, in which they move:

Geostationary satellite. The satellite rotates over the equator at the speed of the earth.

1. The satellite, due to its high orbit, covers a quarter of the Earth’s surface.
2. Satellite is stationary for ground antennas, which greatly facilitates the organization of communication, so there is no need to automatically correct the direction of the ground antenna, as we have to do for low-orbit and medium-altitude satellites.
3. Satellite is at a considerable height from the Earth’s atmosphere, the less wear and tear, which increases its service life. Low-orbit satellites, because of friction against the air, constantly lose altitude and have to regain it with engines.
4. Satellites have a large number of antennas, which allows them to maintain a large number of communication channels.
   To receive a signal from such a satellite, it is necessary to use parabolic antennas up to 10 m in diameter, but with the advent of directional antennas, which were installed on satellites,
   the diameter of the receiving antenna was reduced to 1 m.
   A disadvantage of satellites in geostationary orbits is that they are located at a great distance from the Earth’s surface, which leads to large delays (from 230 to 280 msec) in the transmission of signals. In addition, at such distances are very high signal losses.

Medium-orbit satellites.

These satellites cover 10,000 to 15,000 km of the Earth’s surface and have a delay in signal propagation.
terrestrial territory and provide signal propagation delay of about 50 msec. The most known systems using such satellites are GPS and GLONASS systems.
GPS satellites are located in six planes at an altitude of approximately 20 180 km from the surface of the planet. GLONASS satellites are located in three planes at an altitude of about 19,100 km altitude. The nominal number of satellites in both systems is 24.
Both systems use signals on the basis of pseudo-noise sequences which gives them high noise immunity and reliability at low transmitter power.
According to the purpose, each system has two base frequencies – L1 (standard accuracy) and L2 (high accuracy). GLONASS uses frequency separation of signals, that is, each satellite operates on its own frequency. Each satellite of the system besides basic information transmits also auxiliary information necessary for continuous operation of receiving equipment.

Low Earth orbit satellites.

The main advantage of such satellites – the proximity to Earth, and therefore lower power transmitters, small size of antennas and short signal propagation time (about 20-25 msec). The main disadvantage of these satellites is that They have a very small coverage area – only 8000 km. Revolutions period of such a satellite around the Earth Earth revolution period of such satellite = 1,5 – 2 hours. Time of communication with a base station is approximately 20 minutes. In addition, because of the low orbit, such satellites are very strongly affected by the atmosphere, which limits service life of such satellites 8-10 years. “Iridium and Globalstar are the main companies using low-orbit satellite systems for mobile communications in places where installing cellular base stations is not possible or very difficult.
Now in the Iridium system (Iridium) operates 66 low-orbit satellites, placed on the 6 circumpolar orbits. The mechanism of inter-satellite communications allows to transmit a signal from one satellite to another without retransmitting this signal to the Earth. The bandwidth in each direction is 25 Mbit/s. The Iridium satellites are located 780 km above the Earth’s surface, below all other satellites used by other known mobile satellite communications systems.
The space segment of the Globalstar system includes 48 primary and 4 reserve satellites, weighing about 450 kg each, located in circular orbits in 8 planes at an altitude of 1414 km, 6 satellites in each. “Globalstar” orbits have an inclination of 52 degrees. Thus, Globalstar does not extend to the polar regions. Globalstar satellites have two body-mounted antennas turned toward Earth.

Satellites of highly elliptical orbits.

Elongated elliptical orbits with a perigee radius of about a thousand kilometers and an apogee radius of one or several tens of thousands of kilometers.
If a satellite’s orbit is highly elliptical, it will spend most of its orbital period around the Earth in an area close to apogee where it moves very slowly. This means that the satellite can be within sight of ground stations for most of orbit period, then it disappears from visibility. By placing several satellites in the same elliptical orbit at equal distances from each other, a continuous service effect can be achieved.
Using a High Elliptical Orbit can provide signal coverage anywhere on the globe. The movement of HEO orbits is not limited to equatorial lines, the use of which leads to insufficient coverage of high and polar latitudes.
The main disadvantage of the elliptical orbit is that the position of a satellite in this orbit relative to the ground station position of the satellite relative to the ground station is constantly changing.
Since communications satellites are mostly located near the equator, the lack of communications in the high-latitude Arctic remains a serious problem that needs to be addressed as commercial, scientific, and tourist activities move farther out.
