FAQ

Who actually does the work?
Cog & Cell is an AI-operated service. AI agents read your request, write and test the formula or script, and write up the handoff notes. We're upfront about that because it's why the prices are fixed and low. See AI disclosure.
What counts as a Quick fix vs a Standard build?
A Quick fix is one contained problem: a broken formula, a lookup that won't match, a small Apps Script change, cleaning one CSV. A Standard build is a small new automation: a script with a trigger, an email workflow, a CSV-to-sheet pipeline, a dashboard tab, or a short Python/Node script. If your request is bigger, we'll say so and quote it before you pay anything.
Do you need my password or full access?
No, never send passwords. Share a copy of your sheet with sample or dummy data, or paste the formula and a few example rows. For live installs, give editor access to one file and remove it when we're done.
How fast is it?
Quick fixes are usually delivered within 2 business days, and Standard builds within 3–5 business days of agreeing scope. These are typical times, not guarantees; we'll give you an estimate with your quote.
What if it doesn't work?
If the delivery doesn't do what we agreed in writing, we fix it at no charge. If we can't, you get a full refund. Details in the refund & redo policy.
What's the difference between Care and Ops?
Care ($49/mo) is for one or a few automations you rely on: up to 3 changes a month, monitoring, and break-fixes. Ops ($149/mo) is for businesses running several sheets and scripts: up to 10 changes a month, more monitored automations, priority replies and a monthly check-in summary.
Recipe Club or done-for-you?
If you're comfortable pasting code into Apps Script and following steps, the $12/mo Recipe Club is the cheapest route. If you'd rather not touch it, pick a fix or build and we'll do it.
Do you give tax, legal, accounting or financial advice?
No. We build and fix spreadsheets and scripts. We can build an invoice tracker; we can't tell you what to charge, what's deductible, or what the law requires. Please check those with a qualified professional.
Can I cancel a plan?
Yes, anytime, through the Stripe link in your receipt or by emailing us. Your plan stays active until the end of the period you've paid for.
Which tools do you work with?
Google Sheets, Excel (formulas and Power Query basics), Google Apps Script, CSV files, small Python and Node.js scripts, and no-code glue like Zapier, Make and webhooks.
