Getting this document right
The invoices that get paid fastest are the ones the customer can check line by line without ringing you. Separating labour from parts, naming what was actually done, and referencing the original quote number all remove the friction that turns a two-week payment into a six-week one.
VAT is where plumbing invoices go wrong most often. If you're not registered you must not show a VAT line at all — showing one when you can't reclaim it is an HMRC problem, not a formatting one. If you are registered, your number has to appear and the rate has to be right, including the reduced rate where it genuinely applies. The tool handles this from your account setting rather than leaving you to remember.
Payment terms matter more than most plumbers use them. Naming a due date, the accepted payment methods, and your position on late payment gives you something to point at when you chase. Vague terms make chasing awkward.
Free to use — five documents a month, no card needed.
What people get wrong
Showing VAT when you're not registered
It's not a cosmetic error. If you're under the threshold and not registered, there must be no VAT line anywhere on the invoice.
One lump sum
"Bathroom work — £2,400" invites a phone call. Itemise labour and parts and the customer can satisfy themselves without one.
No due date
"Payment on receipt" isn't a date. Name one, and your chase has a reference point.
No invoice number
Sequential numbering is a basic record-keeping requirement and it makes chasing and bookkeeping far easier.
Write your next one in about twenty seconds.
