When shared spreadsheets stop working, and what a simple custom system can change.
Spreadsheets are a great starting point, but they have limits. Files get duplicated, formulas break, and nobody is sure which version is correct.
A custom system stores your data in one place, controls who can see or edit it, and produces reports automatically. Tasks like issuing invoices, tracking fees or checking stock take minutes instead of hours.
You do not need a huge system on day one. Start with the one process that causes the most trouble, build it well, and add modules as your team gets comfortable.
