System Integration Services That Make Your Tools Work Together
We connect the systems your business runs on — CRM, ERP, ecommerce, finance, marketing and custom software — with secure APIs, reliable data integration and real-time sync, so information flows without copy-paste.
// overview
What are system integration services?
System integration services connect separate software systems so they share data and work as one — using APIs, webhooks, middleware and data pipelines. API integration services link your applications directly, while data integration combines information from many sources into a consistent view.
Disconnected systems create duplicate data, manual re-entry and decisions based on numbers nobody trusts. Good integrations remove that friction — and they are built with error handling, monitoring and documentation so they keep working as your systems change.

// sound familiar?
Signs you need system integration services
If three or more of these sound familiar, your systems are working against each other.
Warning: numbers never match
Reports from different tools disagree on the same figures.
Error: brittle connections
Old integrations break after updates and nobody knows why.
Warning: no API for a key system
A critical system has no easy way to share data.
Error: delays between systems
Stock, prices or statuses update hours or days late.
Warning: new tools mean new silos
Every new app adds another place where data gets stuck.

// how we measure
What we measure on integration projects
We agree these measures with you at the start and report on them in plain language.
01
// manual data entry removed
02
// sync delay before vs after
03
// data errors between systems
// a typical challenge
Distributor whose ecommerce, CRM and ERP each held different customer and order data.
// how we approach it
Two-way integrations with real-time order sync, shared customer records and monitoring for every connection.
// what we report
Progress against the measures above, every month, in plain language.
// who it's for
System integration for growing businesses
For companies whose growth depends on systems that talk to each other.
Ecommerce & Distribution
Orders, stock and customers synced. See trade and wholesale ecommerce.
SaaS Companies
Public APIs and integrations your customers ask for.
Finance & Operations
Accounting, billing and operations data aligned.
Data & Analytics Teams
Reliable data feeds for dashboards & BI.
// real-time sync
Webhooks and real-time sync
When stock, orders or customer details change, every system should know immediately. We use webhook integration and event-driven sync to push changes in real time — with queues, retries and alerts so nothing is lost when a system is slow or offline.
Need actions triggered by those events? See workflow automation.

System integration, explained
What teams ask before connecting their systems.
What is iPaaS?
iPaaS (integration platform as a service) is a cloud platform for connecting applications with prebuilt connectors and visual workflows. It is fast for standard apps and moderate volumes. Custom integrations or middleware suit complex logic, high volumes, legacy systems or strict security needs. Many companies use both.
API integration vs data integration
| Factor | API integration | Data integration |
|---|---|---|
| Purpose | Systems act on each other’s data | Combine data for one consistent view |
| Timing | Real time or near real time | Scheduled or streaming |
| Typical use | Orders, customers, payments | Reporting, analytics, migration |
Integration best practices
- Decide which system owns each piece of data
- Map fields and formats before building
- Use events and queues for reliability
- Handle errors with retries and alerts
- Log every sync for troubleshooting
- Document everything for future changes
How much do system integration services cost?
Cost depends on the number of systems, data objects and sync complexity. Main drivers: systems and APIs involved, two-way vs one-way sync, data volume and real-time needs, legacy systems, and monitoring requirements. After a scoping call you receive a written scope and estimate.

System integration FAQs
Straight answers to the questions we hear before integration projects.
What are system integration services?
System integration services connect separate software systems so they share data and work together, using APIs, webhooks, middleware and data pipelines.
What is the difference between API integration and data integration?
API integration lets systems act on each other’s data in real time; data integration combines data from many sources into one consistent view, often for reporting.
Can you integrate systems that do not have an API?
Often, yes — through database connections, file exchange, middleware or RPA, depending on the system and security requirements.
Should we use an iPaaS or custom integrations?
iPaaS is fast for standard apps and moderate volumes; custom integrations suit complex logic, high volume, legacy systems or strict security. We recommend after mapping your systems.
Do you build custom APIs?
Yes. We design and build APIs for your systems, partners and apps, with documentation, security and versioning.
How do you make integrations reliable?
Clear data ownership, queues, retries, monitoring, alerts and documentation for every integration.
How much do integrations cost?
Cost depends on systems, data objects, sync direction, volume and legacy complexity. After a scoping call you receive a written scope and estimate.
How long does an integration take?
Timing depends on how many systems are involved and the state of your data, and we agree a plan after a short review.
Is our data safe?
Yes. We use your own cloud accounts, role-based access and encryption, choose model providers and settings that meet your privacy requirements, and never use your data to train public models.
Who owns what you build?
You do. You own the code, prompts, workflows, data and accounts from day one. We document everything and offer ongoing support, but you are never locked in.
