No more quotes in Excel
Many businesses in the Netherlands still manage their quotes in Excel or Word, then have to re-enter everything to create the invoice. With the Estimates module from Peppol Box, everything happens in one place: quote creation, client signature, deposits and final e-invoice.
Create and duplicate quotes in a few clicks
The editor uses the same interface as your invoices — familiar territory. Add your line items, pick your customer, set a validity date, and you're done. Need a similar quote? Duplicate and tweak it.
Get your clients to sign online
Send an electronic signature request directly from Peppol Box. Your client receives a secure link, signs online, and you're notified instantly.
During client meetings, you can also get signatures on the spot on your tablet.
Manage deposits without the hassle
For multi-stage projects, generate deposit invoices directly from your quote. The balance is calculated automatically, and the final invoice is created in one click.
From quote to e-invoice in one click
Quote accepted? Convert it into an invoice without re-entering anything. The invoice is automatically ready for the Peppol network.
Who is it for?
Consultants, tradespeople, architects, agencies, freelancers and zzp'ers… Any professional who sends quotes before invoicing will save time and gain clarity.
