Your systems,
finally working as one.
Northern Codes is a UK AI automation agency. We design, build and run the workflow automations, AI agents and integrations that move work between the platforms your business already uses.

What does an AI automation
agency do?
It takes the repetitive work your teams do by hand and builds software that does it instead. We connect the platforms you already run, your accounting, CRM, storefront, support desk and spreadsheets, so work flows between them without a person retyping it.
Finance & Back Office
Invoicing, reconciliation, purchase workflows, reporting packs. The work that has to be right every time, made repeatable and auditable.
Operations & Data Flows
Orders, jobs and records moving between systems automatically, with validation on the way through and an audit trail behind them.
AI Agents & Customer Response
Systems that read, decide and reply: enquiry triage, quote handling, support responses grounded in your own data, escalating to people when judgement is needed.
Integration & Custom Builds
Where nothing off the shelf fits, we build the missing piece: private APIs, internal tools, custom CRMs, joined to what you already run.
How engagements run.
No surprises.
Automation touches money, customers and live data, so the discipline is the product. The same four stages on every engagement, whatever its size.
Discover
We map the manual work: what it costs in hours, where it breaks, which systems it touches and who depends on it. No assumptions, no templates.
Design
You get a fixed quote, a timeline and a preview of what we intend to build. Sign-off happens before the build, not after it.
Build
Built on the platform that fits your workloads and governance requirements, tested against real data, documented as we go.
Run
Monitoring from day one, a close watch through the first weeks, then a clean handover, to us to operate or to your own team.
Governance built in
Access scoped, credentials managed properly, an audit trail on what ran and when.
Data residency, settled first
Some platforms keep processing in Europe; some run through the US. We set this out for your build before you commit.
You own the build
Workflows, code, documentation and credentials are yours. Nothing locks you to us.
Measured,
not promised.
For a UK hospitality staffing company we automated invoicing that was being done by hand, 30 to 40 invoices a week. The automation removes around 22 staff hours every week, and the build recovered its full cost within 60 days.
That is the standard every engagement is scoped against: a measured saving, on a known cost, visible in the first quarter.

AI consultingCommon questions. Straight answers.
What does an AI automation agency actually do?
It takes the repetitive work your teams do by hand, invoicing, moving data between systems, triaging enquiries, compiling reports, and builds software that does it instead. You describe the manual process; the agency designs, builds, tests and runs the system that replaces it, across the platforms you already use.
What does an engagement cost?
Every build is scoped and fixed-price. You get the number, the timeline and a preview of what we intend to build before any work starts, so the decision is made on a known cost against a measured saving. No day rates running open-ended, no surprises after kick-off.
How long does an automation project take?
A single well-scoped automation usually ships in one to three weeks. Multi-system programmes take longer and we say so up front, with the phases set out in the quote. Nothing starts until you have seen the shape of the build and agreed the plan.
Which platforms do you build on?
n8n, Make and Zapier where they fit, custom code where they do not. We hold no reseller deals with any of them, and we publish detailed comparisons of all three so our reasoning is checkable. The platform is chosen for your workloads, volumes and governance requirements, not for our convenience.
Where does our data live?
It depends on the platform, and we set it out for your build before you commit. Some platforms can keep processing in Europe; others process everything in the United States. Where residency matters to you, it becomes a selection criterion for the build, not an afterthought discovered in procurement.
Who owns what you build?
You do. Workflows, code, documentation and credentials are yours, handed over cleanly. We can run and monitor the system for you, or hand it fully to your own team; either way nothing about the build locks you to us.

A call, a straight answer on whether automation is worth it for you, and a fixed quote if it is. If it is not, we will say so.
