What our AI does with WeFact
Use cases
Automatic invoice follow-up
The agent tracks outstanding invoices in WeFact and prepares payment reminders as soon as an invoice is overdue. You review and send — no invoice slips through anymore.
Prepare invoices from other sources
Based on completed projects, time tracking or a CRM deal, the agent creates draft invoices in WeFact. You check the line items and amounts before anything goes out the door.
Debtor overview on request
Ask in plain language about your outstanding items or debtor position. The agent pulls current figures from WeFact and gives you a clear overview, without you having to search yourself.
Match payments to invoices
Incoming payments, for example via Mollie, are linked to the right open invoice in WeFact. Discrepancies or partial payments are flagged for your review.
Pass data to your accounting software
Invoice and customer data from WeFact is prepared for your accounting software, so your books stay in sync without double data entry. You review the transfer.
Flag risky debtors
The agent recognizes customers with a pattern of late payments and prepares an alert. That way you can weigh the credit risk yourself before accepting a new order from them.
