FACTURA INVOICE Help
Clear answers about the current founder preview and the next payment-ready release.
●Founder preview · No billing activeCan I use FACTURA INVOICE now?
Yes. You can create estimates and invoices, calculate deposits and margin, save drafts on this device, print or save PDFs, and export reports.
Is there a free version or trial?
This founder preview is available without billing. Final free-trial terms and subscription pricing have not been activated yet.
Where are my documents stored?
In this preview, drafts and expenses are stored only in this browser on this device. Cloud accounts, team access, and permanent file storage are part of the next integration layer.
Can I convert an estimate into an invoice?
Yes. Use the action button beside an estimate to convert it into an invoice without re-entering the customer, job, or amount.
Can customers pay deposits and milestone payments online?
Yes. Add a verified contractor-owned payment link and generate a printable QR now. Zelle, bank-link, PayPal, Cash App, and other payments require manual confirmation in this preview; automatic Stripe status starts after secure Connect onboarding.
How does commercial repair photo verification work?
Proofstac creates a proprietary evidence record with repair checkpoints, SHA-256 file seals, timestamps, optional jobsite location, QR access, and invoice thumbnails. The preview proves file consistency and recorded context; independent cloud signing is the next layer.
Are there hidden fees or active charges?
No billing is active in the current preview. Processing fees and subscription terms will be disclosed before any paid service is enabled.
