The short version
The most reliable quarterly routine is not a dramatic end-of-period tidy-up. It is a small loop: capture records when they happen, check the exceptions once a week, and review the quarter before it is due.
Capture the event, not the memory
A receipt on the passenger seat or an invoice remembered three weeks later creates uncertainty. Capture the expense or income when it happens, while the supplier and business purpose are obvious.
In SimpleTaxFlow, that can be a receipt photo, PDF, or a plain-English WhatsApp message. The goal is a useful digital record that you can review later, not a perfect piece of bookkeeping prose.
Give yourself one short review window
Set aside a small recurring slot to check Activity for uncategorised and needs-review records. The purpose is to resolve the handful of ambiguous items before they accumulate into a mysterious quarter.
A good review also checks whether receipt evidence is attached, income is complete, and the description explains the business purpose where it needs to.
Use the pre-submission checks as a conversation
Before a quarterly update, ask DUE to identify the next obligation and READY to find the gaps that still matter. Use PREVIEW to inspect the actual figures before submitting.
That sequence matters: it keeps submission as the end of a considered review rather than a button pressed under deadline pressure.
