The Best Invoice Software for Your Trade

BillMate is used daily by thousands of UK workers across dozens of industries. Here's how it works for the most common trades.

Plumbers & Heating Engineers

Raise a VAT invoice the moment you cap the last pipe. Include parts and labour as separate line items, apply the correct VAT rate, and send it before you drive away. Customers pay the same day and your books stay clean for the Gas Safe register and HMRC.

Electricians

NICEIC and NAPIT registered electricians use BillMate to quote jobs, convert to invoices on completion, and track which certificates relate to which invoice. The legal support tools are invaluable on larger commercial contracts where payment can be slow.

Designers & Creatives

Freelance designers invoice for discovery, design and final delivery as separate milestones. Quote-to-invoice conversion means nothing gets re-keyed. Branded PDF invoices make the business look as professional as the work itself.

Builders & Contractors

Construction businesses with multiple active projects track each job's invoices and expenses separately. Stage payments, retention amounts and variations are all handled cleanly. Multi-business profiles suit contractors operating under more than one trading name.

Consultants & Coaches

Business consultants, management coaches and interim managers use recurring invoices for retained clients and project invoices for one-off engagements. The analytics dashboard shows which clients are most profitable and which take longest to pay.

Photographers & Videographers

Creatives working on weddings, events and commercial shoots send deposit invoices up front and final invoices on delivery. Clients can view and accept quotes digitally before the job begins, removing any ambiguity about scope or cost.
