Spreadsheets to systems: when are you ready to switch?

Switching too late costs you orders. Switching too early wastes money. Here is how to tell where you are.

Spreadsheets are not the enemy. They are cheap, flexible and everyone can use them. The problem is not that you use them, it is that at some point you quietly outgrow them, and the cost of staying creeps up where you cannot see it.

The signs you have outgrown them

• Nobody is quite sure which version is the latest.
• One or two people are the only ones who understand the master sheet.
• You find out about problems late, usually from an angry customer.
• The same numbers get rekeyed between sales, planning and finance.
• Growth makes everything slower, not faster.

Why switching too early is also a mistake

A system you adopt before you need it is cost and disruption with little return, and you risk choosing for a business you do not yet have. The trick is timing: modernise when the pain of staying clearly outweighs the cost of moving, not because a vendor told you to.

The low-risk way to find out

You do not have to guess. A short, fixed-scope review maps where your spreadsheets are actually costing you and whether a system is the right next step or whether a few smaller fixes would do for now. Start small, prove the case, then move. That is the whole idea behind how we work.
