FAQs

What does a backend development company do?

Backend development companies develop backend systems for your application, which include all the APIs, databases, business logic, security, and cloud infrastructure, enabling your frontend to work fast and keeping your data secure in the process.

How much does backend development cost

The price of backend development is affected by its scope, technologies used, and the seniority of the team. The offshore rates typically range from $20 to $50 per hour, whereas United States teams' prices start at $100 and increase from there. The simplest applications may start at $10,000, while advanced systems may cost over $120,000.

Can a backend development company modernize legacy applications? 

Yes. Most experienced backend development companies help businesses modernize legacy applications without rebuilding everything from scratch. They can refactor outdated code, migrate databases, redesign APIs, move workloads to the cloud, and gradually transition monolithic systems into scalable architectures while minimizing downtime and business disruption. 

How do I choose the right backend development company?

Consider their technologies, match their expertise in a particular industry, analyze the case studies, and evaluate other factors like communication, security policies, price, and support after deployment. A paid trial period will be the most secure way for you to make sure the company suits your needs.

Should I hire a backend development company or build in-house?

It would be better to choose a backend development company if you want to release an app within a few months. The other option can be applied only in cases when backend will be the core of the business, which means a lot of investments in recruitment.

How long does backend development take?

A simple API may be developed within a few weeks, but the whole backend for the SaaS may be developed in 3-6 months. Sometimes complex enterprise solutions with many integrations may take more time.
