SMEs Vs. Large Companies: What to Choose and Why?

10 Best Fintech Companies in 2024: Full Market Research & Analytics - 13

As you probably understand, the size of a company determines a lot of final results – which product will be developed, at what cost, how and how long. Without any doubt, you are likely to lean towards big fintech companies that are stable and recognized in the globe. This is a widespread belief. But what if you drip deeper and figure it out? Many fintech solutions are created using the same technologies, but at different costs in different companies. As a rule, large companies set higher prices for their services to cover all possible expenses, including overhead and operating costs. 

It may seem that if you have a large staff of experts or many competencies, you are in a strong position. Not always like this! First of all, you have to pay more money out of pocket for not always necessary areas of expertise. Secondly, you cannot be 100% sure that out of the total number of specialists, you will need all of them to successfully complete the project. This is especially true if you are not tech savvy. Thirdly, huge cross-functional teams are not so flexible and adaptable to all possible changes during the development process. 

In addition, keep in mind another important point – most large companies begin to cooperate with customers whose projects are estimated at more than $250,000. So, if you do not plan to launch a large fintech project, do not hesitate to contact a small or medium-sized company, whose technical potential is also great. 

Our blog article, “How to Estimate a Software Project Easily?” also may come in handy if you aren’t familiar with estimation methods in development projects. Follow simple methods on how to estimate the cost of a software project!

The final cost of your product will vary not only within several companies in the USA or any other country, but also on different continents. It is no secret that development costs in Eastern Europe or Asia are lower than in North America or even Western Europe.

Average Costs of Fintech Projects by Region*

North AmericaWestern EuropeEastern EuropeAsia
$200,000+$150,000+$100,000+ $80,000+

* Costs are calculated approximately based on the minimum rates of specialists required for a simple fintech project in each region


Whether you are currently considering a small, medium or large fintech company, you already have enough options. However, many points may influence your final decision. You should take into account the following points:

  • Scope of work;
  • Level of competency;
  • Planned budget;
  • Location of development, etc.

For example, when working with small and medium enterprises, you can focus on saving money if the budget is a key factor that affects your decision. In the case of cooperation with a large enterprise, instead of focusing on prices, you can safely develop advanced functions of your software.

You can benefit from the narrow specialization offered by mid-level companies, such as Mangosot. Our qualified specialists come up with effective solutions, some of which you can study in our examples or contact us for more information about our competency. So, do your best to use Fintech Application Development Services today to be successful tomorrow!
