Hey everyone!
Every solo founder, consultant, and small studio I talked to had the exact same back-office headache: paying $150 $250/mo across QuickBooks, a separate CRM, a task tracker, and an invoicing tool only to export everything back into Google Sheets at tax time anyway.
At the same time, almost every Google Sheets invoice template breaks in real life for two reasons:
1. Using =IMAGE() APIs for payment QR codes triggers Google's scary yellow "trying to send data to external parties" warning banner.
2. You end up manually updating 15+ tabs until a formula breaks.
So for Sheetly Global OS (launching today!), I engineered two things under the hood:
100% local in-sheet QR generation triggered silently when you tick a print checkbox embedding your Stripe/PayPal Scan-to-Pay QR on a clean PDF invoice with zero external API calls.
A single Country Selector on Setup that rewires tax labels, Top 5 CPA write-offs, and a 25% tax reserve across US (IRS Schedule C), UK (HMRC VAT), Canada (GST/HST), Australia (BAS), EU VAT, and 0% Export while you only ever type into 5 simple dropdown/checkbox tabs.
Curious how fellow builders and solo founders here run their invoicing + tax tracking today do you stick with spreadsheets, Notion, or a dedicated accounting SaaS?

Hey Product Hunt! ๐
I built Sheetly Global OS out of a simple frustration: running a small service business, consultancy, or studio shouldn't require paying $150โ$250 every single month across QuickBooks, a separate CRM, a task manager, and an invoicing app โ while still scrambling through spreadsheets at tax time.
At the same time, most spreadsheet templates fail in real life because they're either blank grids where you break a formula on day two, or bloated files where you're expected to manually update 20 tabs every day.
So I engineered Sheetly Global OS โ a ready-made 19-sheet operating system that runs 100% natively inside free Google Sheets, stored privately on your own Google Drive:
โก Zero Daily Overwhelm: You only ever type into 5 simple tabs (Clients, Comm Log, Tasks, Invoices, Income/Expense) using dropdowns and checkboxes. The other 12 dashboards, calendars, and financial reports calculate themselves automatically.
๐งพ 60-Second PDF Invoices + Offline Scan-to-Pay QR: Pick an invoice number from a dropdown to generate a clean PDF bill complete with your Stripe/PayPal Scan-to-Pay QR code (generated 100% locally inside the sheet with zero external-data warning banners!) + 1-click pre-filled Email & WhatsApp payment reminders.
๐ 6-Jurisdiction Adaptive Tax & CPA Hub: Switch your country once on the Setup Page โ formulas, tax labels, Top 5 CPA write-offs, and a 25% quarterly income tax reserve adapt automatically for US (IRS Schedule C / 1099), UK (HMRC VAT), Canada (CRA GST/HST), Australia (ATO BAS), EU VAT, and 0% Global Export.
๐ 100% Private & $39 One-Time: Because you clone a private copy straight into your own Google Drive, we never touch or see your client list, bank balances, or revenue. No monthly subscriptions, no per-seat fees โ just a $39 one-time launch license (including 4 bonus templates & SOPs, backed by our 7-Day Working-System Guarantee).
I'd love your honest feedback โ what tools are you currently stitching together for client billing and tax tracking? Happy to answer any questions about how the Google Sheets architecture works under the hood! ๐
