Why Late Categorization Deletes Deductions
Software totals receipts — it doesn’t invent business purpose or method. Memories fade, context disappears, proof expires. Monthly close prevents that leak.
The Precise Monthly Close That Locks Evidence
5–7 day routine: reconcile accounts, categorize uncategorized, attach receipts + purpose notes, run reports, sign-off. Keeps books fresh and audit-ready.
Category-to-Deduction Rules & Audit-Trail Architecture
Custom chart: Home Office, Mileage, Phone/Internet, Supplies, Education, Software, Travel. Attach notes, receipts, logs. Folder structure + monthly export.
Simple Policies That Make Returns Faster & Safer
Prepaid amortization (12-month rule), travel memos, allocation methods, W-9 gatekeeping. Document once — reuse forever.
Month-End Close Checklist (copy-paste)
☐ Reconcile all accounts
☐ Categorize uncategorized transactions
