Why a generic invoice template falls short on building jobs

01

Construction units built in

Bill by m², m³, bags, tonnes, days or lots — not just "item" — so your invoice matches how the work was measured.

02

VAT handled for you

Switch on VAT and 7.5% is added and shown as its own line, with the total updated automatically.

03

Linked to your BoQ

Pull the section totals from a saved BoQ tender straight in as line items, or bill stage by stage.

Questions

Frequently asked questions

Q.Is the invoice generator free?+

Yes — you can create and print invoices free. Free printouts carry a small nigeriabuildingcost.ng watermark; a 7-day or 90-day pass removes it.

Q.Does it add VAT?+

Yes. Tick "Include VAT" and 7.5% is added to the subtotal and shown as a separate line on the invoice.

Q.Can I bill a construction project in stages?+

Yes. Enter your contract sum under "Bill by construction stage", adjust the percentage for each stage, and add it as a line item — one invoice per stage, or several stages on one invoice.

Q.Do you collect payments for me?+

No. This is an invoicing tool only — we never process, collect or hold payments. Your client pays you directly using the bank details on your invoice.

Q.Can I send the invoice to my client?+

Yes. Log in and save the invoice, then send it to your client by email or copy a payment link to share on WhatsApp.
