About Sage & Vow

Sage & Vow was born from a simple frustration: planning a wedding means tracking hundreds of details across apps, notebooks and group chats — and still not knowing how much you've actually spent.

We build templates that do the work for you. Clean, calm, on-brand with your big day, and built so a couple with zero spreadsheet or design skills can open them and start planning the same evening.

Every template is tested formula by formula, works in Google Sheets, Excel and Canva, and gets free updates for life.
