Duplicate data entry
Move information between systems automatically instead of entering the same details more than once.
API integration services
Need two systems to talk to each other?
Large Solutions builds bespoke API integrations that connect the software your business already relies on — without forcing you to replace systems that otherwise work.
Focused automation and integration projects from £500.
The problem
Good software is less useful when the systems around it stay disconnected.
If staff are copying information between platforms, importing spreadsheets, re-keying orders or checking multiple systems to complete one process, an integration may remove those hand-offs.
Disconnected workflows
Trigger the next step when an order, payment, customer update or other business event occurs.
Manual imports and exports
Replace repetitive CSV and spreadsheet transfers with controlled data synchronisation where the systems allow it.
Integration examples
Connect the systems involved in the real workflow.
The right solution depends on the APIs and data interfaces available. These are common examples rather than a fixed list of supported products.

Bespoke integration
When a ready-made connector is not enough.
Off-the-shelf connectors are useful when the workflow is simple. Bespoke development becomes valuable when you need business rules, unusual data mapping, error handling or a system the standard connector does not support.
Understand the workflow
Identify which systems own the data, what should move between them and what needs to happen when something goes wrong.
Design the integration
Choose the appropriate APIs, webhooks or scheduled processes, with authentication, validation and maintainability considered from the start.
Build and test
Implement the integration against realistic workflows and handle the exceptions that make production integrations different from simple demos.
Deploy and support
Put the integration into use with clear ownership, logging and a practical route for future API changes or enhancements.
Relevant experience
Integration work grounded in software engineering.
Large Solutions works across APIs, backend services, databases, webhooks, payments and automation — including extending existing systems rather than rebuilding them unnecessarily.
Payments
Payment platform integration
API-driven workflows around hosted checkout, saved cards and authorisation/capture handling.
Automation
Data and workflow automation
Processing, transforming and moving data between services with fewer manual steps.
Existing software
Extend rather than replace
Work with existing applications and APIs when the core systems already meet most of the business need.
Pricing
A practical starting point.
A focused integration can often be scoped as a defined project. More complex work may benefit from a short discovery first.

API integration FAQs
Before we connect anything.
What systems can you integrate?
Any suitable systems that expose an API, webhook, database or supported data exchange method can potentially be integrated. The first step is checking what each platform makes available.
Can you work with our existing software?
Yes. Many projects are about connecting or extending software a business already relies on rather than replacing it.
What if there is no ready-made connector?
That is a common reason for bespoke integration work. We can assess the available APIs and data interfaces and determine whether a reliable custom connection is practical.
How much does an API integration cost?
Focused automation and integration projects start from £500. The final cost depends on the systems, authentication, data mapping, business rules, error handling and testing involved.
