Every investment club starts with a spreadsheet. Every investment club eventually breaks one. HWSW does the maths for you — member splits, tax figures, portfolio tracking — automatically.
Free to start. No credit card required.
It's not a question of if — it's when.
New member joins — entire sheet breaks
Recalculating ownership percentages across historic transactions is a full afternoon of formula-fixing. One wrong cell and the gains are wrong for everyone.
Member withdraws — nobody agrees on the amount
Working out exactly what a departing member is owed, factoring in unrealised gains and CGT liability, is almost impossible to do correctly in Excel without accounting training.
Tax time — someone has to do it manually
Extracting each member's share of capital gains, applying Section 104 rules or the correct cost basis method, and preparing figures for self-assessment takes days.
Multiple versions, nobody knows which is current
"Is it the one Dave sent on Tuesday or the one Sarah updated Thursday?" Spreadsheets shared by email are a version-control disaster waiting to happen.
No audit trail when something goes wrong
When a number looks wrong, tracing back through years of formula dependencies to find the error is brutal — and there's no history of who changed what.
