Does this sound like your week?
You started your business to do your craft, not to chase your clients.
- 📞
You still call clients to ask where their payment is
- 📄
A quote has been pending for 3 weeks because the client has to print, sign and scan it
- 💸
Payment delays are blowing up and your cash flow takes a hit at month-end
- 📧
You're writing the same reminder email for the 4th time this week
- 🔌
None of your tools talk to each other: software, email, bank, signature… five apps, five passwords
- 01 Invoices sent as attachments, lost in inboxes
- 02 Chasing payments by hand, one email at a time
- 03 Quotes printed, scanned, signed, re-scanned
- 04 No idea if anything was even opened
- 01 A client portal designed to simplify every interaction
- 02 Reminders that send themselves until you're paid
- 03 One-click e-signature, tracked in real time
- 04 See the moment a document is viewed, paid, signed

What our existing clients say.
The DOOC team listens, is highly professional, and adapted the platform to fit my activity exactly. I no longer chase payments.
A solution that completely simplified my quotes and invoices. I save at least 5 hours a week. Customer service is close, authentic, really listens.
My clients receive their invoice, click, pay with Twint. Average payment delay went from 38 days to 11. Concrete, measurable, changes our cash flow.
I don't change anything about how I work. I keep using Bexio, and DOOC handles all client interactions. Exactly what I needed.
Online signature doubled my quote acceptance rate. Clients no longer hesitate because there's nothing to print anymore.
The portal with my logo is a detail that changes everything. My clients feel like they're dealing with a much larger, more professional structure.

No migration, no complexity, with a real human at the other end of the line when you need one."
