Take a look inside
This is what you get, from day one
Real screenshots of the xInvoice app. No mock-ups, no promises.
From request to payment in three moves
No spreadsheets, no Word files, no email ping-pong.
- 1
Create
Pick the client, add your services: the quote is ready with your logo, your terms and the tax worked out.
- 2
Send
Your client gets a link by email. They read it, sign with a finger or a mouse, and you get notified.
- 3
Get paid
The quote becomes an invoice in one click. The client pays by card or PayPal and the invoice marks itself as paid.
Everything you need to invoice. Nothing you don’t.
One app for your quotes, invoices, payments and clients.
E-signature
Clients accept your quote online. Name, date and IP address are recorded.
Online payments
Card payments via Stripe and PayPal: connect your account in one click, no API keys.
Automatic reminders
Unanswered quotes, invoices about to fall due or overdue: you choose when to nudge.
Mini CRM
Appointments with email reminders to clients, tasks, delivery dates, a 360° client view.
Expenses & reports
Log expenses with receipts, track revenue and export everything for your accountant.
Google Drive
Every document is filed in your Drive automatically. Import from other tools.
Multilingual & mobile
Documents in English, French, Portuguese or Spanish. On desktop, tablet and phone.
E-signature
A quote signed online, not a PDF lost in an inbox
Your client opens the quote on their phone, signs with a fingertip and can even pay the deposit straight away. You see when they opened it, when they signed it — or why they declined.
- Tracking: sent, opened, signed
- Proof kept (name, date, IP address)
- Quote turned into an invoice in one click
Online payments
Paid by card in 30 seconds, straight into your account
Connect your Stripe or PayPal account from xInvoice: a window opens, you log in, done. No API keys to copy. Money lands in your account, the invoice is marked paid and partial payments are handled.
- Cards, Apple Pay, Google Pay (Stripe)
- PayPal
- xInvoice fee: just 1% on online payments
Automatic reminders
Late invoices chase themselves
Set your rules once: a heads-up a few days before the due date, then polite reminders after. The same goes for quotes with no answer. You stay in control of the wording.
- Follow-ups for unanswered quotes
- Before-due notice + overdue reminders
- Editable email templates
Mini CRM
Your appointments and deadlines, right next to your invoices
Book an appointment: the client gets a confirmation with a calendar invite, then an automatic reminder. Track tasks, delivery dates and every client’s pipeline.
- Calendar + email reminders to clients
- Tasks, deliveries, calls, follow-ups
- Client page: quotes, invoices, unpaid, history
Your client's side
Your client signs and pays from their phone
No account, no app to install: one link in an email and it's done.
Less admin, more time for your actual work
Invoicing shouldn’t eat your Sunday. xInvoice brings together what used to be spread across a spreadsheet, a word processor, your inbox and your bank.
