The small print at the bottom of an invoice is the only place your conditions are written down where the customer will see them.
Interest on late payment, goods once sold, warranty periods, jurisdiction: these are the lines nobody reads until something goes wrong, at which point their presence or absence on the bill is the whole argument.
Setting them once means every bill carries them, including the ones raised in a hurry by somebody else. Bank details in the same place save the phone call asking where to transfer the money.
The conditions you actually trade on.
Where you want the money sent.
See it as the customer will.
Every invoice carries them from then on.
The parts that make the app yours: your numbering series, your terms at the bottom of the bill, your branding, more than one firm under one account, and a way to bring existing data in from a spreadsheet instead of typing it.
This is setup work — done in the first week, and then again whenever the business adds a firm, changes a series or closes a year.
The rest of what makes the bill yours.
On the bill itself, in the place the template gives them.
Yes, along with your terms and notes.
Yes once set, including bills raised by staff — which is the point of setting them centrally.
The small print only helps if it is on the document the customer holds.
