I run a Shopify store selling mystery football shirt boxes. Stock in three markets, a subscription base, suppliers on different terms, money moving in four currencies. Not a finance guy. Just a founder who kept getting surprised by his own bank account.
For years I did what everyone does. A cashflow spreadsheet in one tab. Stock levels in another. A sales forecast in a third. Every decision that mattered meant reading all three and doing the joining up in my own head — usually on a Sunday night, usually wrong.
And it was always the same decision that caught me out: how much stock to buy. That's a cash question wearing a stock question's clothes, priced off a forecast. I couldn't find anything that would answer it, because answering it properly needs all three at the same time — and every tool on the app store only does one.
So I built the thing that joins them. It reads my books, my store, my subscription platform and my bank, then models the next 13 weeks properly — payroll on payroll dates, VAT on VAT dates, supplier terms as they actually are rather than as they're written. Now the stock number and the cash number are on the same screen, and the reorder is just obvious.
It changed how I run the business. Reorders happen on a number. Payment runs get approved in minutes. I stopped being surprised. Enough store owners have asked me for it that I've packaged the whole thing up — and made it work with whatever stack you're already on, not just mine.
