Simple Invoice helps freelancers and consultants create repeat invoices from an iPhone in under a minute. Save your business details, clients, payment terms, logo, signature, and PDF design once. Duplicate a previous invoice, change what varies, review the exact document, and share a polished A4 or Letter PDF. FAST REPEAT INVOICES • Save clients and their billing defaults • Duplicate line items, adjustments, and notes • Allocate unique invoice numbers automatically • Track Draft, Sent, Overdue, and Paid states • Use EUR, USD, or save your own three-letter currency • Search and filter your local invoice library OPTIONAL SERVICE AGREEMENTS Write and activate your own reusable Markdown agreement template. Invoice details resolve into the agreement automatically, while agreement-only values can be overridden. Preview invoice and agreement separately, then share them as two PDFs on iPhone. Finalized agreement revisions remain available with sent invoices. Simple Invoice supplies document-generation tools, not legal clauses or advice. YOUR PDF, YOUR DESIGN Choose Clean, Ledger, or Compact. Adjust color, typography, density, page size, logo and signature placement, section order and visibility, labels, payment details, and footer. PRIVATE AND OFFLINE Editable data, agreement templates, revisions, and finalized PDFs stay on this device. There is no account, advertising, analytics, backend, or automatic cloud synchronization. PDFs leave only when you choose a destination in the iOS share sheet. Simple Invoice generates documents but does not certify tax or legal compliance. You remain responsible for requirements in your jurisdiction.
