[GNC] Starting from scratch

[David Warren]

Clint, you can make any of those work.  It all depends on what you are
trying to achieve going forward.

i.e. if you just want to test out gnucash, you could easily start a year
(e.g. 2026) and input opening balances for all asset and liability
accounts.  And just start tracking going forward.  Of course, you will miss
out on certain information, but many of us started out that way.  And, yes,
at any time, for accounts that were open prior to 2026-01-01, you could go
back and add one, five, or inception-to-date entries and just make sure
everything reconciles correctly going backward.  I certainly did some of
that and only added what I actually thought I would later use.  But if you
are not ever going to look back at spending or other reports from 2021 vs.
2031, then there might be no need.  I determined I could get all tax basis
reporting from my brokerage accounts, so why bother duplicating in
gnucash?  But you might want individual tax bases going back many years,
so... your choice.

I think others are answering "if it's easy enough to get your old data
ported, then why not?"  Fair enough.  But until you are fully committed to
using gnucash and figuring out *how *you want to use it and what types of
backward looking reports will be important to you, even an hour of porting
work may not be worth it.  And, yes, you can always do it later.

I will tell you that had I waited until 2026 to do some of my back-porting
work that I actually did myself, WOW is it easier today.  I just ask my
favorite LLM to do 90% of my gnucash entries these days, and life is
dramatically simpler!  Having Claude Code do all my complex splits is
fantastic.  And now it's like I'm talking to a world class accountant,
rather than trying to turn myself into one.  I speak English, and Claude
can turn that into debits and credits.  Worth considering if you have the
chops to use.
