Invoicing for the people who do the work, not the people who file it. Oyster is a phone-native invoicing app for freelancers, contractors and small businesses. The job is done, you are still standing in the client's kitchen or closing your laptop at a cafe, and the invoice is already sent. Four taps, start to finish. FAST BY DESIGN Pick a client, add a line item, send. No laptop, no spreadsheet, no template you have to remember to update. Oyster numbers your invoices for you and keeps the sequence clean. A PDF THAT LOOKS LIKE YOU CHARGE WHAT YOU CHARGE Every invoice generates a real A4 PDF carrying your logo, your business details, your tax ID and your payment instructions. Choose from four invoice designs and save your own presets, so every invoice you send looks deliberate. OYSTER NEVER SITS IN THE MIDDLE OF YOUR MONEY Oyster does not process payments. Your client pays you directly, into your own account, using whatever already works between you: bank transfer, a local instant transfer, a payment app. You set the payment instructions, Oyster puts them on the invoice. ANY CLIENT, ANY CURRENCY Bill a client in New York today and one in Bogota tomorrow. Set the currency per invoice and include the payment details that actually work for that client. KNOW WHAT IS ACTUALLY OWED Outstanding, collected and overdue, at a glance. Record partial payments as they arrive and Oyster keeps the running balance. Mark an invoice paid on the day the money landed, not the day you remembered to check. BUILT FOR HOW YOU ACTUALLY WORK Saved contacts, so the second invoice to a client takes seconds Export to CSV for your accountant or your own records English and Espanol Light and dark Your data is yours: export it, or delete your account, whenever you want WHO IT IS FOR Designers, developers, photographers, consultants, translators, trades, agencies of one. Anyone who does the work and then has to ask to be paid for it. Your first invoice is free. Oyster Pro unlocks everything after that.
