Description
There is no cap on line items. Nothing stops at 26 rows, and nothing gets cut off on page two. Estimate, delivery note, invoice and receipt are all made from the same rows in a single tap.
Solo Invoice is an invoicing app for one-person businesses – freelancers, contractors and side-hustlers who do their own paperwork. No account, no cloud. What you type stays on your device.
NEVER RUN OUT OF ROWS - Unlimited line items; A4 pages are added automatically - The date column is free text: leave it blank or write a period - Units such as hrs, days or pcs - Heading rows to group work into sections - Drag to reorder
FOUR DOCUMENTS, ONE SET OF ROWS - Invoice / Estimate / Packing slip / Receipt - Turn a estimate into an invoice, or an invoice into a receipt, in one tap
SALES TAX, YOUR WAY - Sales tax differs by state and county, so you can enter any rate (e.g. 8.875%) - Per-line tax rates, with a summary per rate - Tax exclusive, tax inclusive, or no tax - You choose the rounding: down, up or half up
PICK A DESIGN (NEW IN 1.2) - Classic, Modern or Minimal - Six accent colors: ink, navy, green, crimson, orange, violet - The preview updates as you choose, and every PDF follows it
KNOW WHAT HAS BEEN PAID (NEW IN 1.2) - Expected payment date and paid date on each invoice - "Paid", "Overdue" and "Due soon" at a glance in the list - Filter to unpaid invoices only - Payment records stay on the device and never print on the PDF
ENTER IT ONCE - Business name, address, phone, email, and your EIN - Payment details: bank, routing number (ABA), account number and SWIFT - Logo and stamp/signature image - Automatic document numbers
SEE IT BEFORE YOU SEND IT - Check every page of the PDF in the app before you share it - Share by Mail, Messages, AirDrop, Files or AirPrint
ALSO FOR OTHER COUNTRIES - Switch any document to US, UK, Australian, German, French or Japanese format – currency, tax names and rates, IDs and payment fields change with it
NO ADS - No ad SDK, no banner covering your buttons
PRICING - A one-time purchase. Nothing more to pay afterwards - No in-app purchases and no subscription - Every feature is available from the start, with no caps on documents or line items
YOUR DATA - What you enter never leaves your device. To improve the app, only anonymous usage data (such as which screens are opened) is counted with Google Analytics (you can turn this off in Settings). - No sign-up - Export a JSON backup before you change phones, and CSV for your bookkeeping
