AI Integration Services for UK Firms on Xero, Sage and Business Central

AI integration means wiring an AI model into the software a business already runs, so it reads real records and writes its result back where staff work. A model that drafts a supplier query is a toy until it can see the purchase order in Sage or Business Central and save the draft against it. The connection, the permissions and the checks are the integration. The model is one part of it.

Four we scope often for UK firms. An AI reads a PDF supplier bill and drafts it in Xero with a proposed nominal code. It reads a trade customer’s emailed purchase order and drafts the sales order in Business Central or NetSuite. It sorts Amazon.co.uk buyer messages that stall an order in Linnworks. It drafts a “where is my order” reply from the ERP record and the latest Royal Mail event. A person approves each one before it posts or sends.

Often the tool you already license is enough. Microsoft says Copilot in Business Central comes with the licence at no extra cost, on Business Central online only. Zapier says it connects more than 10,000 apps. A custom AI integration earns its cost when one job crosses several systems, such as Linnworks, a marketplace and Xero, or needs your own approval and audit rules. The comparison table on this page sets the options side by side.

In five moves. Pick one job with a clear measure, such as coding supplier invoices. Map the records that job touches and the system that owns each. Connect through the system’s own API with the narrowest permissions that work. Put a person’s approval in front of anything that posts money or messages a customer. Then test on a few hundred real past cases before it touches live data.

No single model wins every task. We pick per job, usually from Anthropic’s Claude, OpenAI’s GPT models and Google’s Gemini, and test two of them on your own past cases before choosing. The model sits behind your own integration layer, so it can be swapped when a provider retires a version or a better one appears, without rebuilding the links into Xero or your ERP.

AI development builds new software, such as an internal tool or a custom agent. AI integration connects AI to software you already own and keep, so staff see results inside Xero, Business Central, Linnworks or the helpdesk they already open each day. Most projects mix both. If you need a new application built, see our UK AI development page.

Yes. Typical jobs are reading supplier invoices and proposing the nominal code (the ledger account a cost is posted to) and VAT rate, matching remittances to open invoices, and drafting credit-control emails from aged debt. On Sage we first confirm which product you run, because Sage 50, Sage 200 and Sage Intacct connect in different ways. Nothing posts to the ledger until a named person approves it.

Yes. Microsoft’s documentation says its APIs are enabled by default on Business Central online and use standard REST calls (the common way software asks a web service for data), so any language that can call REST can connect. It also says the standard APIs cannot be extended with extra fields, so a custom field means a custom API page. We check your extensions on the scoping call for that reason. Read on 29 October 2026.

On the right plan. Odoo’s own documentation says access to data through the external API is only available on Custom pricing plans, and not on One App Free or Standard. It supports API keys in place of a password, shown once and impossible to restore after deletion. Check your Odoo plan before scoping, because it decides whether a direct link is possible.

Yes, at the exception stage. Linnworks, Brightpearl and Mintsoft already move routine orders. AI earns its place on the awkward ones: an address Royal Mail or Evri will reject, a buyer message asking to change a size, a listing on ManoMano or the B&Q marketplace whose stock disagrees with the warehouse. It reads the order, proposes the fix and a person accepts it.

Yes. NetSuite projects usually centre on sales orders, item records and customer service history. A common first job is reading inbound purchase orders from trade customers, by email or PDF, and drafting the NetSuite sales order for a person to check. We agree with your NetSuite administrator which roles and records the integration may touch before anything is built.

Through the ERP’s own API, under a dedicated user or role with only the permissions the job needs. The agent reads items, prices and open orders, and writes drafts, not posted documents. On Business Central that means its REST APIs. On Odoo it needs a Custom plan. On NetSuite we agree roles with your administrator. Every action lands in an audit log. In this kind of AI systems integration the ERP stays the record owner, and the agent only proposes.

Yes, for reconciliation and follow-up rather than for taking payments. Examples: explaining why a GoCardless Direct Debit failed and drafting the customer note, or splitting a Klarna or Clearpay settlement into the orders inside it so the books match the bank line. The AI reads payout and transaction records. Card numbers and bank details stay with the payment provider.

Within limits. GOV.UK says the Data (Use and Access) Act 2025 replaces Article 22 of the UK GDPR with Articles 22A to 22D once that section is commenced, allowing solely automated decisions in wider circumstances if safeguards are in place. The safeguards include telling people about significant decisions, letting them challenge one and letting them get human intervention. We design approval steps in from the start. Your data protection lead signs off the use.

In stages. GOV.UK says the Act received Royal Assent on 19 June 2025, and that regulations brought most of its data protection and privacy provisions in Part 5 into force on 5 February 2026. The ICO says its guidance on AI and data protection is under review because of the Act. So check the current ICO wording before you finalise a data protection impact assessment.

It can support them. HMRC’s VAT Notice 700/22 lists API transfer and automated data transfer as accepted digital links, and says copy and paste between programs is not one. An integration that moves figures into Xero, Sage or QuickBooks by API stays on the accepted side. Whether your whole VAT set-up complies is a question for your accountant, and we build to their posting rules.

It can. Article 2 of the Act covers providers placing AI systems on the EU market, wherever they are based. It also covers providers and deployers (firms that use an AI system in their work) outside the EU when the system’s output is used in the EU. A UK firm selling into Germany or Ireland with AI facing those customers should check its position. Take legal advice on your own case.

The European Commission’s page says the Act entered into force on 1 August 2024, prohibited practices and AI literacy rules applied from 2 February 2025, and general-purpose AI obligations from 2 August 2025. It became applicable on 2 August 2026 with exceptions. Rules for the high-risk uses listed in Annex III, such as hiring and credit scoring, were extended to 2 December 2027 by the AI Omnibus, which entered into force on 27 July 2026.

You choose. The AI provider account and the hosting can sit in your own name, at cost with no markup through us, so the contract and data terms are between you and the provider. We set it up on the provider’s business or API terms, which you read and accept in your own name, and we record which personal data each step sends to the model. Fields the job does not need are left out.

Market figures vary with the systems involved. Cloudswitched, a London-based managed IT services provider, published these integration ranges on 12 April 2026: £2,000 to £5,000 for one modern API, £8,000 to £25,000 across several SaaS platforms, £15,000 to £40,000 per legacy or on-premises system, and £25,000 to £80,000 for custom middleware. Its page does not say whether VAT is included. These are market figures. FactoryJet quotes a fixed price in writing after scoping.

It depends on the number of systems and the state of their data. One job across one system, such as invoice coding into Xero, is the shortest kind of project. A job that spans an ERP, a warehouse system and two marketplaces takes longer, mostly in agreeing record owners and testing awkward cases. The timeline goes in writing with each phase’s quote, after we have seen your systems.

Yes. Before a contract, we show working software on your own data. For an integration that usually means a sample of your real invoices, orders or tickets run through a test copy of the link, with the AI’s proposals shown next to what your team actually did. You judge it on your own cases.

Yes. Name the systems involved, with versions and editions (Sage 200 or Intacct, Business Central online or on-premises), rough monthly volumes, who approves changes, and any procurement or security questionnaire. Email the file to connect@factoryjet.com, or use the Send my brief button on this page. Bhavesh replies within 24 hours with questions or a call slot.

Check five things before you sign. They show working software on your own data first. Each phase has a fixed price, quoted in writing. You own the code and the repository. The AI and hosting accounts can sit in your name, at cost. A person approves anything that posts to the ledger or messages a customer. An AI integration specialist who will not agree to these is asking you to carry the risk.

You own the code and the repository from day one. Defects are fixed inside the build price for a cover period agreed before work starts. After that, support is optional: each change is quoted and approved before we do it, with no monthly minimum. FactoryJet quotes the build, and any support you choose, as fixed prices in writing.
