Wedding-in-a-Box — plan the entire wedding in ONE spreadsheet instead of 47 open tabs. 15 ready tabs: budget with plan-vs-actual and automatic overspend alerts, guest list for 150 guests with RSVP / meals / thank-you tracking, seating chart that checks table capacity itself, a 31-task countdown checklist from 12 months out, minute-by-minute day-of timeline, vendor payment tracker, and a question bank to ask EVERY vendor before signing (hidden fees, rain plans, overtime rates). The dashboard counts everything for you: budget health, RSVP totals, planning progress and days to go. BONUS: a printable 6-page Day-Of Kit PDF (master checklist, emergency kit, contacts, vendor confirmations). Excel + Google Sheets, EN + RU, no macros, no passwords, demo data included. Normally $39 — one-time purchase, yours forever. What you get: a ready-to-use wedding_in_a_box.xlsx file. Works in Excel 2016+ and Google Sheets, English. Instant download, free re-downloads forever, 14-day money-back guarantee.
