System Integration Services: ERP, CRM and API
What Is System Integration? Enter Data Once, Use It Everywhere
System integration connects separate software, such as ERP, CRM, web shop, payment gateway, e-invoicing, courier and SMS services, through their APIs so data moves between them on its own. An order is entered once; stock, the invoice and the shipment are created in the other systems automatically. We connect what you already use and log every transfer.
Accounts live in one package, sales in another, the web shop and courier portal in separate browser tabs. An order is taken in one place, invoiced in another and deducted from stock in a third, with staff re-keying the data in between. It costs hours, the figures drift apart, and by month-end nobody is sure which screen is right.
Once the systems are integrated, that re-keying disappears: when an order is placed, stock is reduced, the invoice is issued, a shipment is booked and the customer receives tracking details. We build the links to keep a log of every transfer, so when one fails you can see which record is stuck and the right person is alerted.
For international companies operating in Turkey, this is often where local requirements bite: GİB e-invoicing, Turkish banks' virtual POS systems and local ERPs such as Logo and Mikro need to talk to your group systems. We handle both sides.
System Integration Scope: What We Connect
ERP:
Two-way transfer of sales, stock, customer account and accounting data with Logo, Mikro, Netsis, SAP and bespoke ERPs.
CRM & HR:
Customer records, order history and call logs into Salesforce, HubSpot or your own CRM; staff data kept in step with HR and payroll software.
Payments:
Card collection through iyzico and Turkish banks' virtual POS services, with the payment result posted to the order and customer account automatically.
e-Invoice / e-Archive:
Invoices created and sent through GİB-approved integrators, so a completed sale produces its invoice without anyone typing it.
Couriers & Logistics:
Shipments booked and tracking numbers retrieved through carrier APIs such as Aras, Yurtiçi, MNG and UPS, with tracking details sent to the customer.
SMS & Email:
Order, appointment and payment notifications through SMS providers such as Netgsm and Twilio, and through email platforms.
Maps & Location:
Address validation, route planning and field team locations via Google Maps and similar services.
Bespoke & Legacy Systems:
Including older or poorly documented software: REST, SOAP, GraphQL, file exchange or direct database links, whichever the system allows.
Two Ways to Work With Us
Every integration starts with a data map: where each piece of information originates, where it needs to go, and which system is the master for each field. Scope, phases and cost are then set out in a written proposal. From there, one of two routes applies:
Connecting Your Existing Software
It does not matter whether we or another vendor supplied it. If it offers API access, we connect it to the rest of your systems and your teams keep working in the screens they know.
New Software, Integration Built In
Software we build for you is designed with its connection points from day one, so adding a new bank, carrier or marketplace later does not mean reworking the system.
See also API Integration for API development on the software side, and Integrated Systems for bringing several modules under one roof.
If you are setting up a new sales channel, our own SmartSales e-commerce platform brings orders, payments, shipping, returns and marketplace integrations into one panel; the storefront, marketplaces and product feeds all draw on the same catalogue. To buy SmartSales, simply complete the SmartSales form.
Questions We Hear Before an Integration
- "Our software has no API." That is not always a blocker. During discovery we look at routes such as file exchange or a direct database link, and the proposal states which one can be applied safely.
- "What if a link drops; do we lose data?" Every transfer is logged. A stuck record does not disappear silently: you can see which record failed and why, and the responsible person is notified.
- "Will our team have to give up the software they know?" No. The integration sits between your systems; everyone keeps working in their own screens, and only the manual re-keying goes away.
- "Who looks after it once it is live?" The same team that built it, with technical support available 24/7.

Digital Bridge has been building software and hardware for businesses across Turkey from its base in Adana since 2013. Where an integration has a hardware side, such as moving data from readers, scales or field devices into your software, the same team handles both. Start with a list of the software you want to connect: we will map the data and send scope and cost in a written proposal.
Questions we hear most often
Frequently Asked Questions
What is system integration?
System integration connects separate software, such as ERP, CRM, web shop, payment gateway, e-invoicing, courier and SMS services, through their APIs so data moves between them on its own. An order is entered once; stock is reduced, the invoice is issued, the shipment is booked and the customer receives tracking details, with no re-keying.
Which systems do you integrate?
Logo, Mikro, Netsis, SAP and bespoke ERPs; Salesforce, HubSpot or your own CRM; HR and payroll software; iyzico and Turkish banks' virtual POS services; e-invoice and e-archive through GİB-approved integrators; carriers such as Aras, Yurtiçi, MNG and UPS; SMS providers such as Netgsm and Twilio; and map services such as Google Maps.
Can you connect our group systems to Turkish e-invoicing and local ERPs?
Yes. For international companies operating in Turkey, GİB e-invoicing, Turkish banks' virtual POS systems and local ERPs such as Logo and Mikro often need to exchange data with group systems. We handle both sides of that connection, starting from a data map that sets which system is the master for each field.
Do we need to replace our software to integrate it?
Usually not. Whether we or another vendor supplied it, if the software offers API access we connect it to the rest of your systems and your teams keep working in the screens they know. For older or poorly documented software we look for another route: REST, SOAP, GraphQL, file exchange or a direct database link.
What happens when an integration fails?
Every link is built to log each transfer. When one fails, you can see which record is stuck and the right person is alerted. Problems are therefore spotted when they happen rather than at month-end when the figures no longer match, and you can trace when each record was transferred.
How does an integration project start?
Every integration starts with a data map: where each piece of information originates, where it needs to go and which system is the master for each field. Scope, phases and cost are then set out in a written proposal, and you choose between connecting your existing software or new software built with integration in from day one.
