I don't use Lyx for invoices or any documents with calculations in them. Instead I use Latex usually (depending on what I am doing) with the letter class adapted for window envelopes and my header. Latex takes care of the typesetting and a program called Scrivener looks after the arithmetic.
Grahame, Business A/P checks are processed and printed from GnuCash; personal checks are hand-written. All business invoices are LyX letters for professional services. When a project is on a retainer basis I invoice the initial retainer amount and provide a montly statement of the account, now using the KOMA-Script article class with spreadtab and longtable. When the retainer needs replenishing I send another letter invoice along with the statement. Other than A/P vendor payments which are physical checks sent via snail-mail, all other documents are transmitted as PDF attachements to e-mail messages. (I even recycle the bits!) I recently learned that I could use gnumeric to track retainer payments and draws and have the results automatically reflected in the LyX article's table, but that involves another application. The spreadtab package will do the calculations directly. Happy holidays, Rich
