Quiet Engine Co. · Texas
We're a small Texas shop making practical spreadsheets, planners, PDFs, AI agent skills and n8n workflow templates. Plain files you download and own, built to save you an evening, not to sell you a system.
A turkey timeline built backward from dinner time, and a gift & budget tracker for the season.
A 2027 planner with a Schedule C P&L, logs and a rough quarterly tax estimate. Not tax advice.
SKILL.md skills for everyday admin: inbox triage, quotes, review replies, invoices and weekly numbers.
Importable workflows for holiday orders, plus a skill that helps your agent build and check workflow JSON.
Spreadsheet + PDF
Enter your dinner time and turkey weight; get the thaw start, USDA 325°F oven times (stuffed or unstuffed) and an hour-by-hour timeline, plus menu/oven, guest, shopping, prep and leftovers tabs and an 8-page printable.
2 spreadsheets + PDF
Both holiday spreadsheets for $12 ($16 separately): the Thanksgiving turkey timeline planner and the gift & budget tracker.
Spreadsheet
Per-person gift budgets, a gift log from idea to given, other holiday spending, ship-by dates you enter yourself, a card list and a dashboard. Room for 60 people and 300 gifts.
Spreadsheet
Budget, goals, a monthly P&L by Schedule C line, income/expense/mileage logs, a 1099 contractor tracker and a rough quarterly tax estimator. Not tax advice.
5 agent skills
Inbox triage + reply drafts, quote builder, review replies, invoice reminders and a weekly KPI digest. Everything is a draft you approve; scripts do the math. ($25 if bought separately.)
4 n8n workflows
n8n workflows for Shopify, Stripe or Gumroad sellers: log orders to Google Sheets, send thank-you emails, flag low stock and get a daily sales digest. Independent; not affiliated with n8n.
Spreadsheet + 1-page PDF
Enter the weight, fridge or cold water, and the oven time; it shows when to start thawing and the USDA thawing range. Thaw times only, not roasting times.
