Three steps. Invoice sent.

No templates to fill in. No software to learn. Just describe the job and copy the result.

1

Describe the job

What you did, how long it took, what materials you used. Short notes are fine — "replaced consumer unit, 4 hours, parts £180" is enough.

2

Get your invoice

Flint writes a fully itemised professional invoice. Labor, materials, VAT, payment terms — laid out properly and ready to send.

3

Copy and send

Hit copy. Paste into an email or WhatsApp. Your customer gets a clean, professional invoice while you're still packing up your van.

A proper invoice. Not a scribbled note.

Flint uses real trade pricing and terminology — not generic figures from a spreadsheet template.

📋

Fully Itemised

Labor, materials, call-out fees, and sundries broken out line by line. Customers see exactly what they're paying for — which means fewer payment disputes and faster payment.

💷

VAT & Tax Handling

UK invoices include VAT where applicable. US invoices handle sales tax. Totals are clear and correct — keeps you compliant without the admin headache.

Electrician Invoice Templates

Consumer unit replacements, EV charger installs, rewires, service upgrades — Flint knows what electrical work costs and writes the invoice correctly. No more copy-pasting old invoices and hoping the numbers are right.

🔧

Boiler services, bathroom installations, emergency callouts, leak repairs — plumbing invoices done in seconds with correct labour rates and parts pricing built in.

📅

I used to batch my invoices at the end of the week. Now I send them from the van before I drive off. I swear I'm getting paid a week faster on average.

I'm a one-man shop. Used to take me Sunday evenings to catch up on invoicing. Now it's done on-site and I have my weekends back.

Common questions.

Yes. The free tier gives you access to the invoice generator and other tools with no credit card required. We have a paid plan for unlimited use, but you can generate real invoices on the free tier today.
Yes. When you sign up, you select your region. UK invoices include VAT at 20% where applicable, with correct VAT number fields. US invoices handle the appropriate tax treatment. Both formats are clean and professional.
Yes. Flint gives you a solid first draft — copy it and edit anything you want to change before sending. Most tradespeople use it as-is or adjust one or two line items. It's a starting point, not a locked document.
Flint does both. The quote generator is for pricing a job before you start — the invoice generator is for billing when the job's done. They're separate tools in the same account. Most tradespeople use both.
Plumbing and electrical are fully supported right now. HVAC support is coming very soon — along with builders and roofers. Each trade gets dedicated terminology and pricing, not a generic template.
