Fill in the client's details — the price calculates itself, just like the calculator on the website — and when you're done tap Create PDF: your phone shows the share menu to send the letterhead sheet to the client or save it.
In Deep and Move-In/Out, baseboards and doors & frames are already included.
If you add a line with an amount, that line takes over and replaces the automatic calculation. Delete it and the calculator's price comes back.
The estimate is also available as text with "Copy text", in case you want to paste it into a message.
