Answers to common questions. The same topics are available offline in the Android app.
Getting started
Learn the basics and set up your account
From Home, tap + and choose Create Invoice. Add a client and line items, then save as draft or mark as sent. Preview and share a PDF from the invoice detail screen. Free plans can create up to 10 new invoices per UTC calendar month; older invoices stay visible.
Yes. Invoices, clients, catalog, and expenses live on this device first. You can start as a guest without an account. When you sign in and go online, changes queue for cloud sync. Local work is never blocked waiting for the network.
Open More → Business profile for name, address, and tax details. Logo and brand colour are under More → Branding. These appear on PDF invoices when set. MVP supports one business profile.
Use the in-app encrypted portable backup (and optional Drive) to export or restore your business data. Android Auto Backup does not include your financial database. Cloud sync (when signed in) is also available on Free and Pro.
Clients and payments
Manage clients, payments, and estimates
Go to More → Clients and tap Add. You can optionally import from device contacts — contacts stay on-device unless you save them as clients. Pick a client under Bill To when creating an invoice. Free plans can keep up to 3 live clients (delete one to add another).
Open an unpaid invoice, then use Mark as paid or Add payment. Partial payments update the balance. Payment history is under More → Payments. The app records payments for your books — it does not process card payments for your clients.
Estimates (quotes) let you send pricing before work starts. Convert an estimate into an invoice from the estimate detail screen (that counts as a new invoice create). Free plans allow 10 new estimates per UTC calendar month.
Add reusable products or services under your catalog (Free: up to 5 live items). Expenses can be recorded without a Free create cap. Tax fields are guidance only — you remain responsible for correct tax in your jurisdiction.
Premium and privacy
Billing, features, and data security
Free (per business, UTC month): up to 10 new invoices and 10 new estimates, 3 live clients, 5 live catalog items, 5 email sends, PDF with watermark, and 5 templates to use (you can preview all 50). Free may see ads; Invoice Maker Pro is ad-free. Invoice PDFs stay ad-free. Pro also removes the watermark, unlocks all templates, removes create caps, and unlocks full reports and CSV export. Cloud sync and portable backup are available when signed in on Free and Pro. Open More → Upgrade for the live comparison; Google Play prices are authoritative.
On the paywall or Premium screens, tap Restore and sign in with the same account that purchased. Entitlements are verified with our servers after Google Play confirms. To stop renewals, cancel in Google Play → Subscriptions. Cancelling stops future charges; it does not automatically refund the current period. History is never wiped when Pro expires.
Business data stays on your device until you sign in and sync. We do not sell invoice contents to advertisers. Free may see Google AdMob ads; Pro does not; invoice PDFs stay ad-free. We may use Firebase Analytics and Crashlytics for reliability. Optional contact import is on-device only unless you save clients. Optional biometric app lock stays on your device. Read the Privacy Policy and Cookie Policy on this site or under More → Legal in the app.
In the app: Settings → Account → Delete Account (reauthenticate and confirm). You have 7 days to sign in again and cancel deletion. After that window, personal data is anonymized and eligible data is erased on our schedule (about 30 days after anonymization). You can also use Delete account on this site. Cancel your Google Play subscription separately to stop renewals. Export anything you need before confirming.
Troubleshooting
Fix common issues and reach support
Ensure the invoice has a client and at least one line item, then try Preview again. Free PDFs include a watermark; Pro removes it. If share still fails, free some device storage and retry, or contact support with the invoice number.
Cloud sync needs a signed-in account and a working connection. Open More → Sync status to see the outbox. Local edits remain safe on the device; sync retries when the network returns. You can also use encrypted portable backup to move data.
You can share a public link or QR from an invoice. Recipients open it in a browser at invoice.dsource360.com/i/…. Optional PIN or expiry may apply. Shared pages show the document you chose to share — they are not a full web login for your account.
Use More → Contact us or More → Feedback in the app, or email support@invoice.dsource360.com. Include your app version and account email (never your password). We aim to reply within 1–2 business days. Android is the primary app today; iOS and a signed-in web workspace are planned.
