Cost per home is a guess
Materials arrive on many invoices from several merchants. Allocate invoice lines to each job or home to see real cost, materials versus labour, before the next job is priced.
Nexus Business Register for home energy upgrade and retrofit contractors
Supplier and job cost control for home energy upgrade contractors
Retrofit and home energy upgrade contractors buy large volumes of insulation, windows and doors, ventilation, heating systems, heat pumps and solar PV across hundreds of homes, and rely on installers and subcontractors to deliver them. Margins depend on knowing what each home really cost, catching material price rises early and keeping supplier and installer evidence ready when it is asked for.
Match supplier invoices to projects without the admin headaches, and stay ISO-ready at the same time.

The problems we solve for home energy upgrade and retrofit contractors
Material prices move quietly
Insulation, heat pumps, cylinders and PV panels change price between orders. Price tracking flags real unit-price changes so they can be challenged or passed on.
Deliveries do not match invoices
Link purchase orders and delivery evidence to the invoice to see whether what was ordered and delivered to site is what was billed.
Installer and supplier paperwork is scattered
Keep certificates, insurance and registration evidence against each supplier and installer, with reviews and expiry-aware checks, ready for customer, scheme or audit questions.
Invoice volumes are high
Upload invoices and confirm the details instead of typing them; duplicates are flagged before they are paid 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.
Learn more →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.
Learn more →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.
Learn more →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.
Learn more →Upload and confirm invoices
No typing necessary. Upload the supplier invoice; we do the hard work and you just confirm or approve. Invoices already uploaded are flagged, and each one stays linked to its supplier, approval and project.
Learn more →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.
Learn more →Questions from home energy upgrade and retrofit contractors
Can we see the materials cost of each home we upgrade?
Yes. Allocate supplier invoice lines to a project or job for each home, including materials versus labour, and Nexus reports allocated spend and cost mix per job.
Can Nexus track price changes on insulation, heat pumps or solar panels?
Yes. Nexus compares unit prices for the same item from the same supplier across confirmed invoices and flags material changes, keeping quantity changes separate.
Can we keep installer and subcontractor documents in one place?
Yes. Certificates, insurance and other evidence can be held against each supplier or installer and reviewed with blockers such as missing or expired evidence highlighted.
Does Nexus submit SEAI grant claims?
No. Nexus manages supplier, purchasing, invoice and job-cost records; grant applications and claims continue through the scheme's own processes.
