Meet Christopher

I create straightforward Excel and Google Sheets trackers for small businesses—organising enquiries, quotes, follow-ups and stock in one clear place. I tailor each sheet to your process and test it with sample entries before handover. My portfolio features self-directed examples using fictional data.
