Frequently asked questions
Which invoicing software also has contracts?
SmartWerk is one of the few freelance tools that combines invoices and contracts in one platform. Tools like Moneybird, e-Boekhouden and Boekhoudgemak offer no contract functionality.
Can I create an invoice directly from a signed contract?
Yes, on PRO and PREMIUM. After digital signing, start an invoice from the contracts list with the same client, rate and payment terms — no separate invoicing app or copy-paste.
How does the digital signature work?
You create the contract and send a link to your client. The client signs in the browser, no account needed. A PDF archive is created with timestamp.
Can I also send payment reminders?
Yes. Invoice list → Remind = one payment-due-soon notice before or on the due date (up to 7 days before; BASIC+: one per invoice, max. 10 on BASIC). Overdue follow-up (friendly → firm → final) is in Reminders (PRO+) only. PREMIUM adds automatic overdue follow-up.
Is SmartWerk suitable for international clients?
Yes. SmartWerk supports 7 languages and you can create invoices in euro, pound, dollar or other currencies.
What is the advantage over Word and Excel?
No manual formatting, no version control, no searching for files. Everything is online, always available, with automatic PDF export and client dossier.
