Comparison
An Assembly (formerly Copilot) alternative, simpler
Assembly, formerly Copilot, is a full client portal. If what you mainly need is to get things from your clients, with no tool for them to learn, Ouifait goes straight to the point.
Assembly in short
An American company, Assembly (Copilot until 2025) brings messages, files, invoices, contracts and embedded apps together in one client space. It's powerful, but it's a whole tool to set up, for you and for your clients.

Frequently asked questions
Does Ouifait handle invoicing?
No: Ouifait shows a deposit (amount, IBAN, SEPA QR code, your payment link), but doesn't replace your invoicing software.
Can I use Ouifait alongside another tool?
Yes, that's common: Ouifait handles what the client has to do, the rest stays in your usual tools.
