Built a month-end close system for freelance bookkeepers — sharing what's in it

After looking at the workflows freelance bookkeepers actually use at month-end, I noticed a consistent gap: no standardized system. Every close looked different. Clients sent documents late, reconciliation errors piled up, and there was no template for "please send me these exact 5 things by the 5th."

So I built one. Three documents.

1. Month-End Close Checklist
5-phase workflow, 40+ line items, tagged [QBO] or [Xero] throughout. Phases: Pre-Close Setup → Transaction Coding → Bank Rec → Adjusting JEs → Final Review. Sign-off table at the bottom so the client is on record that everything's been reviewed.

2. Client Document Request Email Templates
9 templates covering the whole relationship lifecycle: standard doc request, two follow-ups (friendly → firm), payroll urgent, unknown transaction inquiry, new asset purchase, report delivery, scope creep, and end-of-engagement. Copy-paste, edit the [brackets], send.

3. Reconciliation Error SOP
10 common reconciliation errors, each with a diagnostic table and the exact fix steps. Includes journal entry examples for the Credit Card Payment as Expense error — the one that creates a doubled liability and confuses clients every time.

One thing I fixed that most templates online get wrong: the Retained Earnings formula. Most say "Prior Year RE + Net Income YTD" — but that ignores distributions/dividends paid during the year. The correct formula is RE(beginning) + Net Income YTD − Distributions paid YTD. Small thing. Wrong thing to hand a client.

Everything runs as HTML files — open in a browser, print to PDF if needed. No app, no subscription, works offline.

It's live at nexusai82.gumroad.com/l/bookkeeper-kit ($39).

Question for the community: do freelance bookkeepers here use standardized templates across clients, or is it always built fresh per engagement? Genuinely curious how common the "figure it out each time" approach is.
