Product 01
Giant Tiny
Office
A calm back office for independent professionals. Create invoices and quotes, track time and payments, prepare recurring work, and keep useful reports—all from one private Android app.
Know what is owed
Payments, overdue balances and unbilled time stay visible without an accounting maze.
Keep control of the record
Your data lives locally. Export backups and documents whenever you choose.
Practical guide 01
Build with Codex.
Keep your hands on the wheel.
CODEX 2026 is an eight-session beginner builder’s guide with a complete Community Help Finder companion project.
Built differently
Less software.
More agency.
Most business tools become platforms. Ours stays a tool: useful immediately, understandable completely, and quiet when you are not using it.
Paid once
Buy the app instead of renting access to your own workflow.
Local-first by design
Business and client records remain in the app’s private storage on your device.
Share only when you choose
Email, PDFs, reports and backups leave the app only through actions you initiate.
Useful without surveillance
No ads, developer analytics, behavioural tracking or hidden marketing profile.
Three clear steps
From work
to invoice.
Set up your business once, record the work, and create a polished document when it is time to bill.
Add your details
Business identity, clients, services, tax and payment instructions stay ready for reuse.
Create the work
Build an invoice directly, convert a quote, or turn tracked time into line items.
Review and share
Export or email a professional PDF using the apps already on your device.
Launching on Google Play
One purchase.
No monthly meter.

Plain answers
Questions
The product is intentionally straightforward. So are the answers.
Does Giant Tiny Office need an account?
No. There is no Giant Tiny Office account or developer cloud service.
Where is my information stored?
In the app’s private storage on your Android device. You can create your own backup files and store them wherever you choose.
Does it connect directly to Stripe or PayPal?
No. You may add your own payment instructions or link to an invoice, but Giant Tiny Office does not process payments or monitor your financial accounts.
Can I email invoices?
Yes. Giant Tiny Office hands the recipient, message and PDF attachment to a compatible email app you select.
Is this accounting or tax advice?
No. It is a record and document tool. You remain responsible for checking local invoicing, tax and record-retention requirements.
