Connect Your Systems with CRM, ERP and API Integrations

When sales works in one system, accounting in another and the e-commerce site somewhere else entirely, the same information gets entered again and again, figures don't match and errors are inevitable. With CRM, ERP and API integrations we connect these systems so data stays correct and current in one place.

Our service covers CRM and ERP connections, e-commerce, payment and shipping integrations, custom API development, data mapping and transformation, error handling and monitoring. We plan it together with our custom software development, reporting and dashboard systems and legacy system modernization work.

Who Is It For?

Which Businesses Is System Integration Suitable For?

It suits businesses of any size that use several software systems and want to automate the data flow between them.

Teams Entering the Same Data Twice

Teams that enter orders, customers or invoices by hand into more than one system.

E-Commerce Businesses

Companies that want to synchronize order, stock, price and invoice data between the online store and ERP.

Sales Teams Using a CRM

Sales organizations that want to connect customer, quote and order data with accounting and ERP.

Dealer and Branch Networks

Organizations that need data flow between a central system and dealer or branch applications.

Users of Third-Party Services

Businesses that want to connect payment, shipping, e-invoice, SMS or marketplace services to their system.

Teams With Legacy Systems

Companies that want an old application to talk to new systems without replacing it.

Frequently Asked Questions — CRM, ERP and API Integrations

We answered the most common questions about the integration process, security, data consistency and cost.

It is the automatic exchange of data between CRM and ERP systems. For example, a quote approved in the CRM becomes an order in the ERP, and stock and invoice information flows back to the CRM. The same data is no longer entered in two places.
An API is an interface that lets software talk to each other under defined rules. API integration means securely setting up one system to read data from, or send data to, another.
We can work with almost any system that offers an API or database access, including CRM, ERP, accounting, e-commerce, payment, shipping, e-invoice and marketplace services. In the first analysis we confirm the integration options of the system concerned.
Often yes. Through database access, file transfer or a custom middle layer, we can make an old system talk to new ones. We settle the method after analysis.
We use authorization, encrypted connections, access restrictions and transaction logs. Secrets are kept outside the code. For integrations involving personal data, we also take data protection requirements into account.
It is chosen according to need. Critical data such as orders and stock can move instantly or event-based, and reporting data on a schedule. We set the frequency of each flow according to the business requirement.
Failed transfers are logged, retried automatically and, after a set point, the relevant person is alerted. So errors don't go unnoticed and no data is lost.
It depends on scope. A simple flow between two systems can be done in a few weeks; multi-system, complex processes take longer. After the first analysis we give a clear plan and timeline.
