What is Nexus Business Register?

Nexus Business Register is one register for suppliers, spend and compliance evidence, built by Nexus Digital in Galway, Ireland for small and medium-sized businesses. It keeps suppliers, purchase requests and approvals, supplier invoices, spend reporting and forecasting, supplier reviews and ISO audit evidence in one workspace. An asset register for devices and software is coming soon.

Does Nexus Business Register include an asset register?

Not yet. A digital asset register for laptops, phones, software and licences is coming soon inside Nexus Business Register. If you need one today, Nexus Digital can set up and maintain an asset register for you as a service.

Who is Nexus Business Register for?

Owner-managed businesses, sole traders and growing SMEs that buy from several suppliers and want to control spend and keep evidence without the cost and complexity of enterprise procurement software. It suits trades and construction, professional services, hospitality, retail and other businesses in Ireland and the UK.

What problems does it solve?

It replaces supplier spreadsheets, retyped invoices, informal purchase approvals and scattered evidence with one system. Businesses use it to see what they spend and with whom, stop duplicate payments, spot supplier price increases, cost jobs accurately and answer audit or customer supplier questions quickly.

How is it different from accounting software?

Accounting software records the financial transactions. Nexus Business Register manages what happens before and around them: who the supplier is, whether the purchase was approved, whether the invoice matches what was ordered, what it cost per job and whether the supplier was checked. Accounting integrations with QuickBooks Online and Xero are planned.

How does it save time and money?

Upload and confirm replaces invoice retyping; it builds the supplier and subscription register from confirmed invoices, flags duplicate invoices and supplier price rises before you overpay, shows recurring costs before they renew and reveals the real cost of each job.

Is it procurement software for small businesses?

Yes. It provides purchase requests, approvals and supplier controls sized for small businesses, with owner-controlled purchasing for sole decision-makers and role-based approval for teams.

How much does Nexus Business Register cost?

There is a free 30-day trial with an allowance of 50 supplier financial documents per month. Essentials is €25 per month including VAT for 250 supplier financial documents per month. Professional is €47 per month including VAT for 1,000 supplier financial documents per month.

The problem it solves

Managing a business means keeping track of dozens of moving parts. When supplier costs creep up, assets go missing, or an auditor asks for ISO evidence, spreadsheets fall apart. Nexus Business Register consolidates your three most critical operational workflows into one unified command centre.

Designed around how your business buys

Keep purchasing accountable without inventing approval steps.

If you are the sole decision-maker, Nexus records your purchasing decision as an owner confirmation rather than pretending that another approver exists. The audit trail still captures the request, decision, supplier, value, evidence and timing. Small teams can add a manager or finance approval where it is useful, while higher-risk or higher-value controls can be introduced without making every purchase difficult.

Owner-controlled purchasingRecord request → Owner confirms → Procure

Clear accountability without an artificial self-approval loop.

Small teamRequest → Manager/owner approval → Procure

Keep one clear decision owner.

More controlRequest → Role-based approval → Procure

Add rules by value, risk or category only where the business needs them.

What Business Register looks like in practice

No typing necessary.

Upload a supplier invoice and the details are prepared for you. You just confirm or approve.

Catch price rises.

Invoices priced above the last one are flagged before you pay, so increases are questioned, not missed.

Know what is coming.

Expected spend from recurring invoices, this week and this month, before the bills arrive.

Stay audit-ready.

Every approval and change is kept with its evidence, ready for ISO and customer audits.

Cut down supplier and invoice admin

Upload it once. Confirm the details instead of re-entering them.

Nexus can structure supplier, invoice and purchasing information around the business record. The direction is simple: upload the evidence, capture the useful details, assign costs to the right person, licence or business use, and let the user confirm rather than repeatedly type the same information.

ExampleMicrosoftCloud productivity · approx. €1,200/year

“Microsoft 365 licences for five staff.”

Suggested details must be reviewed before they become a business record.

Work toward compliance as part of normal purchasing

Procurement can become the clean starting point for the rest of the business.

Nexus keeps supplier, approval, invoice, ownership and evidence records structured as you work, so audit readiness does not become a separate project later. Supplier purchasing can later feed asset creation and approved accounting integrations. QuickBooks Online and Xero connectivity remain planned capabilities, not required to use Nexus Business Register today.

Supplier→Request→Confirmation / Approval→Purchase→Invoice / Receipt→Owner / User→Asset / Accounts

Everything in one workspace

Match supplier invoices to projects without the admin headaches, and stay ISO-ready at the same time. No typing necessary. We do the hard work, you just confirm or approve.

Supplier register

One accurate list of who the business buys from: suppliers, categories, owners, status, evidence and spend in one place, instead of scattered across inboxes and spreadsheets.

Upload and confirm invoices

Purchase requests and approvals

A simple request, review and decide flow for purchases, sized to the business: owner confirmation when one person decides, role-based approval when a team needs it.

Spend analytics

Clear reporting on what the business spends, with whom and on what, built only from confirmed invoice evidence so every number can be traced back to its source.

Price mismatches and supplier price anomalies

Know at a glance when something on a supplier invoice is not right: a unit price that changed, an invoice that does not match what was ordered or delivered, or the same invoice arriving twice.

Project and job cost allocation

Put supplier costs where they belong. Allocate invoice lines to a project, job, reporting unit or cost type and see what each job really cost.

Supplier reviews and due diligence

Structured supplier reviews that gather the evidence, highlight blockers and record a clear decision, so you can show customers, auditors and insurers how suppliers were checked.

Audit trail and compliance evidence

Build audit readiness as a side effect of normal work. Every request, decision, invoice and review is recorded, and audits, findings and corrective actions have their own register.

Invoices, payments and cash due

A clear accounts payable flow for supplier invoices: confirm them, queue them for payment, see what cash is due and when, and keep finance reminders in one place.

Software subscriptions and licences

Every software subscription and licence the business pays for, with its billing cycle, seats, renewal date and owner, built from the invoices you already confirm rather than a separate spreadsheet.

Supplier offboarding and renewal notice

Stop paying for suppliers and subscriptions you no longer need. Nexus tracks renewal dates and notice periods, and gives offboarding a clear process with a reason, evidence and actions, so cancellations happen before the next bill, not after.

Supplier import and onboarding

Get started without a data project. Import the suppliers you already use, add new ones with only the essentials, invite the people who need access and choose how purchasing is approved.
