InvoiceFlint: Invoice & Quote

InvoiceFlint is a simple invoice, quotation and receipt maker for freelancers, contractors and small businesses. Create an invoice, estimate or receipt in under a minute and send it as a PDF by WhatsApp or email, or print it.

Start right away, with no account needed. Sign in whenever you want your invoices backed up and synced to a new phone.

INVOICES IN UNDER A MINUTE
Pick a template, add your client and items, and send. Your logo, signature, payment terms and due date are added for you. Totals, discounts and tax are calculated automatically, so the invoice maker does the maths for you.

ESTIMATES AND QUOTES THAT TURN INTO INVOICES
Use it as an estimate maker and quotation maker before the job starts. When the client says yes, convert it into an invoice with one tap. No re-typing.

RECEIPTS ON THE SPOT
Give a signed receipt the moment a client pays, including cash jobs.

SEND BY WHATSAPP OR EMAIL
Share a clean PDF invoice on WhatsApp, by email or any app on your phone. Clients don't need to install anything.

KNOW WHO HAS PAID
See paid, unpaid and overdue invoices at a glance. Send payment reminders instead of chasing clients.

TAX, VAT AND GST
Save your tax rates once and reuse them. Works for sales tax, VAT and GST, with multi-currency and local date formats.

WORKS OFFLINE
Make invoices on a job site, in a basement or with no data. Everything syncs when you are back online.

NEVER LOSE YOUR BILLING HISTORY
