ERP, CRM & API integrations

Make Your Systems Work Together Without People Holding Them Together

Reliable integrations for the systems, data and workflows your business already depends on.

When ERP, CRM, ecommerce and operational systems do not exchange information properly, people end up filling the gaps with spreadsheets, rekeying and manual checks.

Structurell designs, improves and troubleshoots integrations so the right information moves between systems reliably, with clear ownership when something goes wrong.

Discuss Your Integrations See Common Problems

The Same Data Is Entered More Than Once

Teams are copying customer, order, product or pricing information between systems because no single flow can be trusted end to end.

Failures Are Hard to Trace

Something stops syncing, but nobody can quickly tell where the failure happened, what was affected or who owns the fix.

Important Logic Exists in the Wrong Place

Pricing, stock, account rules or business logic has been duplicated across systems and now behaves differently depending on where it runs.

One Change Breaks Something Somewhere Else

The integration has grown without clear boundaries, making routine upgrades or platform changes much riskier than they should be.

Connected business systems

The Integration Is Usually Part of a Bigger Workflow

We look at what the data means to the business, which system should own it and what needs to happen when the normal flow fails.

Business data

Clear ownership and dependable movement between systems.

ERP

Products, stock, pricing, customers, orders, fulfilment and financial data.

CRM

Customer records, opportunities, account information and sales activity.

Ecommerce

Catalogue, customer accounts, pricing, orders and self-service workflows.

Custom Software

Internal applications, portals and operational systems with their own data and processes.

External Services

Payments, logistics, suppliers, marketplaces, identity services and specialist APIs.

Reporting & Automation

Data movement that supports reporting, workflow automation and better operational visibility.

Decide Which System Is Responsible Before Connecting Everything

Start with ownership

A lot of integration problems are really ownership problems.

If several systems can all update the same customer, product or pricing information, the technology quickly becomes harder to reason about and failures become harder to recover from.

Structurell helps define where important data should live, which direction it should move and what each system is responsible for before adding more technical complexity.

How we approach integration work

Understand the Workflow, Then Design the Data Movement

The API is only one part of the problem. The useful design starts with what the business expects to happen from beginning to end.

01
Map the Process
Understand the people, systems, data and exceptions involved in the real workflow.
02
Define Ownership
Decide which system owns each important piece of information and where business rules should live.
03
Build the Flow
Implement the APIs, events, queues or scheduled processes needed to move data reliably.
04
Make Failure Visible
Logging, retry behaviour and monitoring make it clear when something has failed and what needs attention.

Clear Ownership

Everyone knows which system is responsible for each important piece of data.

Predictable Failure Handling

Retries, exceptions and manual intervention are designed rather than improvised after something breaks.

Useful Monitoring

Failures and unusual behaviour are visible before users have to discover them.

Idempotent & Safe Processing

Retries and duplicate events do not quietly create duplicate orders, records or other unintended effects.

Maintainable Boundaries

A future upgrade to one system should not require understanding an undocumented chain of side effects elsewhere.

Business Rules in the Right Place

Pricing, stock and customer logic are not duplicated unnecessarily across every connected system.

Existing integrations

You Do Not Have to Replace an Integration Just Because It Is Messy

Sometimes the sensible answer is to stabilise what exists, improve visibility around it and remove the highest-risk parts gradually.

If the current integration genuinely needs replacing, we can establish that from the evidence rather than starting with a rebuild assumption.

After delivery

Keep Important Data Flows Visible

Integrations continue changing as APIs, platforms and business processes evolve. Ongoing technical assurance can help catch problems before another workaround becomes permanent.

Explore Ongoing Technical Assurance

Monitor

Know When Something Stops Working

Track failures, queues, slow processes and relevant production behaviour.

Review

Check Significant Changes

Review changes to integrations, APIs and surrounding systems where technical risk is higher.

Improve

Fix the Right Problems

Use evidence from real operation to decide where further engineering is actually worthwhile.
