Massive Invoice

Massive Invoice is offline-first invoicing for freelancers and small businesses. Create an invoice, send a PDF, track who owes what, and get reminded to chase late payments — with no account, no server, and no bank sync. YOUR DATA STAYS ON YOUR IPHONE Clients, invoices, payments, templates, and your logo live in a local store on your device. There is no cloud account to create and nothing uploaded to our servers. MAKE AND SEND INVOICES FAST • Add clients (including from Contacts) • Line items, tax, discount, and multi-currency • Due dates with presets or any custom date • Three PDF templates with live preview • Share or email the PDF from your own Mail TRACK PAYMENTS AND REMINDERS • Status derived from payments and due dates (Draft, Sent, Paid, Overdue, Partially paid) • Record full or partial payments • Local reminders around the due date that open a prefilled email — you send from your own address BUILT FOR TRUST • Export everything as CSV or JSON, and import a prior backup • Plain-language privacy: no servers, no account, data stays on device • Manual payment link you control, printed on the PDF Honest about what Milestone 1 does not do: no bank sync, no “viewed” tracking, and reminders do not send email in the background — iOS does not allow that, and we will not pretend otherwise.
