We Map the Systems
The data models, APIs, and constraints of every system to be integrated are documented. We map out which data flows in which direction, and when.
- System inventory analysis
- Data flow map
- API & format documentation

Talking to Each Other
We seamlessly connect your ERP, CRM, and third-party services through API integrations.
Our Solutions
Which Problem Are We Solving?
Data mismatches between systems, a manual transfer burden, or a fragmented infrastructure — whatever integration problem you're facing, we solve it.
01
Business System Integration
Automated data flow between ERP, CRM, accounting, and HR systems. When an order is entered into the ERP, the CRM updates automatically and an accounting record is created. Manual transfers, human error, and data inconsistency disappear.
02
E-Commerce & Payment Integration
Full automation with marketplaces like Trendyol, Hepsiburada, and Amazon, and payment systems like iyzico and Stripe. Real-time synchronization of order, stock, invoice, and shipping data across all channels.
03
API Development & Third-Party Integration
REST or GraphQL API development so your software can talk to the outside world. If your existing systems don't have an API, we build one; if they do, we integrate with it.
04
Data Migration & Synchronization
Moving data from your old system to a new one. Years of accumulated data is cleaned, transformed, validated, and transferred to the target system. A phased migration plan is prepared for a seamless transition.
How We Work
Integration Delivery in 6 Steps
From system analysis to a live integration — we move forward at every step while preserving your existing infrastructure.
We Design the Integration Architecture
The middleware layer, data transformation rules, error handling, and retry strategy are designed. We determine whether real-time or batch processing is needed.
- Middleware & bus architecture
- Data transformation rules
- Error & retry strategy
We Build the Connection
Connectors, data transformers, and workflow engines are developed. An API layer is added without touching existing systems; your production system runs without interruption.
- Connector development
- ETL pipeline setup
- Existing system stays untouched
We Verify Data Integrity
End-to-end testing is done with real data. Edge cases (null values, duplicates, format errors) are tested with particular care. Zero tolerance for data loss or corruption.
- End-to-end data testing
- Edge case testing
- Performance & load testing
We Deliver a Seamless Transition
With a phased rollout plan, the old and new integrations run in parallel. The old method is switched off only after everything is verified. A rollback plan is always ready.
- Phased rollout
- Parallel-run period
- Rollback plan ready
We Monitor Continuously
Integration success rate, latency, and error metrics are tracked from a monitoring dashboard. Automatic alerts fire on anomalies. Response is free under the 12-month warranty.
- Real-time metric monitoring
- Automatic error alerts
- 12-month technical warranty

We Won't Break Your Existing System
We always validate integrations in a test environment before going to production. We add an API layer on top of your existing system without touching it — production doesn't stop, data doesn't break.
Every Integration Is Observable
Every integration we deliver includes a monitoring dashboard. How many records were processed, how many failed, what's the average latency — you see it in real time.
Broad System Compatibility
We have experience integrating with ERP, CRM, e-commerce platforms, payment systems, and custom software. We can work with systems that have API documentation and those that don't.
Error Handling Comes Standard
A retry mechanism, dead letter queue, and automatic alert system are a standard part of every integration. Our team gets notified before you even notice something went wrong.
What You Get
What Do You Receive From the Project?
Every integration project's standard delivery package includes 6 components.
Working Integration
An integration that is live, tested, and running with monitoring tools installed.
SLA & Support Agreement
A service level agreement covering defined response times, priority levels, and a maintenance schedule.
Technical Documentation
Data flow diagram, API reference, transformation rules, and an error code guide.
Monitoring Dashboard
A ready-made dashboard for transaction volume, success rate, latency, and error metrics.
12-Month Technical Warranty
Integration errors and compatibility issues caused by system updates are resolved free of charge for 12 months.
Rollback Plan
A procedure for reverting to the previous state and an emergency response guide for unexpected issues.
Frequently Asked Questions
Everything You Want to Know
Have another question in mind? Let's talk directly.
We start with a scope analysis: documenting which systems, which data, and which business rules will be integrated. After validating in a test environment, we prepare a go-live plan. We share every step with you.
No. We validate integrations in a test environment before moving them to production. We add an API layer without touching your existing systems; a rollback plan is prepared in advance for every project.
Yes. We integrate through an API layer or middleware without changing your existing systems. Your systems keep running as they are — we just build a data bridge between them.
Yes. With webhook, event streaming, or polling architectures, we can sync data within seconds. We choose the best method together based on your latency tolerance.
A retry mechanism, dead letter queue, and alert system are a standard part of every integration. Our team receives an automatic notification when an error occurs; response is free under the 12-month warranty.
