Why a spreadsheet falls short for invoices and stock

A spreadsheet is cheap and familiar. The issue is not the formula; it is that stock, invoice and customer become three files you have to keep in sync.

MyFileTracker ties those three together. An order can hit inventory and become an invoice, without copy-paste. That is bookkeeping, not a growth hack.

The price is €15 per month or €150 per year after 30 days free. A card is required to start; you are not charged during the trial.
