Scale ERP Integration
ERP integration that keeps every system on the same page.
Your ERP holds the stock, the orders and the invoices. If the website, the CRM and the reporting each keep their own version, somebody is reconciling it by hand. We connect them, and when the ERP itself is the problem we implement and migrate it.
The service
What is ERP integration?
ERP integration services connect your ERP to everything that needs to read from it or write to it.
The ERP is meant to be the system of record: what you have, what you sold, what you are owed. It only earns that title if the other systems defer to it. When the website keeps its own stock figure and the CRM keeps its own customer list, you have three records and no answer.
Sometimes the integration is the whole job. Sometimes the honest answer is that the ERP is the wrong one, or was never set up properly, and that is work we do too: selection, implementation and migration.
Systems mapped before they are automated Deliverables
What’s included
Connections into the system of record, plus the implementation and migration work for when the ERP itself needs sorting.
ERP selection and implementation
Choosing and standing up the right system, scoped against how your business actually runs rather than against a feature list.
Data migration and reconciliation
Customers, stock, history and balances moved across, then reconciled line by line before anyone relies on them.
Website and e-commerce connections
Live stock, pricing and orders moving between the shop and the ERP, so the site never sells what you cannot ship.
CRM and finance connections
The CRM and the accounts reading from the same record, so sales and finance stop arguing about the number.
Monitoring and alerts
Failed records queue rather than disappear, and a broken connection reaches a person the same day.
Why it matters
Two versions of the truth.
Every disconnected system creates a second answer to the same question. The ERP says there are four in stock, the website says six, and the difference is found by a customer. Nobody budgets for that. It is paid for in refunds, apologies and the hour somebody spends every Friday squaring the two.
The cost compounds as you grow. More orders means more reconciling, so the back office has to expand to keep up with the front. Connecting the systems is what lets volume go up without headcount going up with it.
See the results →What you get
One system of record, and proof it agrees.
ERP work judged on whether the numbers match without anybody checking them by hand.
One stock figure
The shop, the warehouse and the accounts read the same number, so the site never sells something that has already gone.
A reconciled migration
Old and new run in parallel and the figures are matched line by line. You sign off the numbers before anything is switched off.
Nothing fails in silence
Failed records queue rather than disappear, and a broken connection reaches a person the same day.
How we work
From two sets of numbers to one.
Map the data
What lives where, which system should own it, and where the two disagree today.
Fix the process first
An ERP configured around a broken workflow just enforces it. The process gets straightened out before anything is built.
Build and run in parallel
Connections built, then old and new running side by side until the figures match.
Reconcile, cut over, monitor
You sign off the numbers, we switch over, and alerting watches it from there.
Our approach
Migrated in phases, reconciled before cutover.
ERP work goes wrong in one predictable way: a big-bang switch over a weekend, found to be wrong on the Monday. We do not work like that. Systems run in parallel, figures are reconciled against the old ones until they match, and you sign off the numbers before anything is turned off.
We map the process before configuring anything, too. An ERP set up around a broken workflow just enforces it, which is why this often starts as a business process design job.

Questions
Frequently asked.

Microsoft Dynamics 365 Business Central, Sage, NetSuite and the usual finance platforms at that end, plus anything that exposes an API or a supported data connection. Where a system has no safe route in, we will say so rather than promise a workaround we would not trust ourselves.
Usually not, and we will tell you when that is the honest answer. Most of this work is connecting what you already run. Replacement is a much bigger decision and should be driven by the system genuinely not fitting the business, not by it being awkward to integrate.
Longer than an integration, and it depends almost entirely on how clean the existing data is. We scope the data before quoting, because that is the part that surprises people rather than the build.
It is migrated, reconciled and kept. You also keep a readable copy of the old system’s data independently of the new one, so nothing important depends on a licence you have stopped paying for.
