ERP software for growing UK businesses

Nexa AI ERP is an AI-native ERP platform for UK small and mid-sized businesses. It connects finance, sales, purchasing, stock, warehousing, production and people in one system, with embedded AI that answers questions about your own business data in plain English.

What is ERP software?

ERP (enterprise resource planning) software is the system a business uses to record and connect its core activity in one place: finance, sales, purchasing, stock, warehousing, production, projects and people. Instead of each team keeping its own system or spreadsheet, every transaction is recorded once and is visible, with the right permissions, to everyone who needs it.

A sales order reserves stock, a goods receipt updates inventory and the supplier ledger, and a manufacturing order consumes materials and records their cost. Because the records are connected, the finance team works from the same figures as operations, and reporting does not depend on reconciling exports from separate tools.

Why growing businesses move to ERP

Most businesses start with accounting software, a few specialist tools and a lot of spreadsheets. That works until the volume of orders, products, sites or people makes the gaps between systems expensive. Common signs include:

  • Month-end takes days because figures have to be collected and reconciled from several systems.
  • Stock figures in the warehouse, the sales team and the accounts do not agree.
  • The same order, invoice or product is keyed in more than once.
  • Managers ask for reports that someone has to build by hand.
  • Approvals for spend and exceptions happen by email, with no audit trail.
  • Adding a new site, company or product line means adding another spreadsheet.

If several of these apply, read our guide to moving from accounting software to ERP.

Disconnected systems

What disconnected systems cost a business

The problems are rarely one big failure. They are small, repeated costs that grow with the business.

01

Duplicate entry

The same data is typed into several systems, which takes time and introduces errors.

02

Delayed reporting

Reports wait for exports and manual reconciliation, so decisions are made on old figures.

03

Limited visibility

Nobody has a single, current view of stock, orders, cash and margin together.

04

Weak control

Approvals and changes are hard to trace when they happen outside the system.

Integrated operational management

In Nexa, finance and operations share one operating model. The main business processes run end to end inside the same system:

  • Order to cash. Quotation, sales order, picking and dispatch, invoice, receipt and credit control.
  • Procure to pay. Requisition, purchase order and approval, goods receipt and put-away, invoice matching and supplier payment.
  • Plan to produce. Bills of materials and routing, production planning, manufacturing orders, material consumption, batch tracking and quality control.
  • Record to report. General ledger, journals, budgets, fixed assets, intercompany transactions and consolidation, with custom dashboards and reporting.

Role-based permissions, approval workflows and audit history apply across every module, and APIs, imports, exports, multi-company and multi-currency support are available throughout the platform. Read about the Nexa platform.

Embedded AI in your ERP

Nexa is AI-native: its AI is part of the ERP rather than a separate tool working from exports. Powered by a locally hosted large language model (LLM), Nexa AI lets your team:

  • ask questions about business data in plain English;
  • get explanations of why figures have moved;
  • receive proactive alerts when targets are at risk;
  • review recommendations, then approve, edit or reject them.

Where the AI proposes an action, it is carried out only after a user approves it. What is AI-native ERP?

Questions you can ask

Illustrative examples of plain-English questions:

  • Why did gross margin drop this month?
  • Which customers have overdue invoices?
  • Where are stock shortages developing?
  • Which purchasing patterns require attention?

Illustrative examples, not actual AI outputs.

What a connected ERP changes

  • One version of the figures. Finance, sales and operations report from the same records.
  • Less re-keying. A transaction entered once flows through to stock, ledgers and reporting.
  • Faster answers. Questions that used to need a report can be asked of Nexa AI directly.
  • Clearer control. Approvals, permissions and audit history sit inside the system.
  • Room to grow. Multi-company and multi-currency support and a scalable multi-tenant architecture are designed for growing organisations.

What to check when choosing ERP software in the UK

Whichever system you consider, these questions help separate a good fit from a good demo:

  1. Process fit. Walk through your real order, purchasing, stock and month-end processes, not a generic script.
  2. UK requirements. Confirm how the system supports your VAT, statutory reporting and payroll arrangements, and which parts are handled by the ERP and which by a connected service.
  3. Data migration. Agree which records and how much history move across, and who cleanses them.
  4. Integrations. List the systems that must stay, such as e-commerce, banking or carrier tools, and how each will connect.
  5. Control. Check roles, approval limits and audit history against how your business signs off spend and exceptions.
  6. AI governance. Ask what data the AI uses, who can see its answers and whether it can act without approval.
  7. Implementation. Ask for a scoped plan with milestones, named responsibilities and a cut-over approach.

How a Nexa implementation works

Each implementation is scoped individually. A typical sequence is:

  1. Demonstration. A walkthrough of the modules, Nexa AI and the controls relevant to your workflows.
  2. Scoping. A review of the modules, users and existing systems involved, and the business data to be brought into Nexa.
  3. Configuration. Setting up roles, permissions and approval limits to match your organisation.
  4. Agreed timeline. Milestones are agreed for each project rather than fixed in advance.

Preparation on your side makes the biggest difference: named process owners, a decision on how much history to migrate and time set aside to clean customer, supplier and product records.

FAQ

Common questions

What is ERP software?

ERP (enterprise resource planning) software records and connects a business’s core activity, such as finance, sales, purchasing, stock, production and people, in one system, so every team works from the same data.

Is ERP only for large companies?

No. Growing small and mid-sized businesses use ERP when the cost of running separate systems and spreadsheets becomes significant. Nexa is designed for growing UK small and mid-sized businesses, particularly manufacturers and wholesale distributors.

What is the difference between ERP and accounting software?

Accounting software records financial transactions. ERP connects those transactions to the operational activity that creates them, such as orders, stock, warehousing and production. Our guide to moving from accounting software to ERP explains the difference in more detail.

Which modules does Nexa include?

Eleven: Finance & Accounting, Fixed Assets, Sales Management, Purchasing & Procurement, Inventory & Stock, Point of Sale, CRM, Warehouse Management, Manufacturing & Production, Projects & Job Costing, and HR & Payroll.

How is AI used in Nexa?

Nexa AI is embedded in the ERP and powered by a locally hosted large language model. It answers plain-English questions using your business data, explains why figures moved, flags risks with proactive alerts and suggests next steps. Actions it proposes are carried out only after a user approves them.

How long does an ERP implementation take?

It depends on the modules, users, data and integrations involved. Nexa implementations are scoped individually and milestones are agreed for each project rather than fixed in advance.
