FAQ

Is Sanso compatible with my existing tools?
Yes. Sanso integrates with Pennylane, QuickBooks, Xero, your email, and your CRM — no need to change how you work.
How can I recover an unpaid invoice quickly?
To speed up payment, you need to follow up at the right time, personalize the message, choose the right channel, and reach the right person. The Sanso AI Agent automates all of this: it analyzes the context, detects no-response situations, autonomously finds decision-makers via LinkedIn or Apollo, works with your internal teams, and communicates directly with your clients until payment is made.
What’s the best tool to automate invoice follow-ups?
Sanso is more than a reminder tool — it's an AI-powered collections platform. It personalizes every message, chooses the most effective channel, finds the right contacts, and manages each invoice until payment is received.
How does Sanso compare to QuickBooks, Pennylane, or Xero reminders?
Built-in reminders send generic emails on fixed dates. Sanso understands the client's history, adapts each follow-up, uses multiple channels to increase success rates, interacts with your team for the right information, and communicates directly with clients to unblock payments faster.
What should I do if a client ignores my reminders?
If a client stays silent despite your follow-ups, you need to identify the right person to contact and vary your channels. Sanso’s AI agent automates this: it detects no-response situations, works with your internal teams to get up-to-date information, and autonomously finds the right contacts via LinkedIn, Apollo or other databases. It then communicates directly with them until the invoice is settled.
How can I improve collections without hiring more staff?
Outsourcing saves time, automation ensures speed and consistency. Sanso gives you the best of both: like an outsourced service, it handles everything end-to-end; like an automated tool, it works continuously without human intervention. It personalizes follow-ups, finds the right contacts via LinkedIn or Apollo, communicates with your clients, and manages each invoice until payment is made.
How can I cut the time I spend on late payments?
On average, Sanso customers spend less than 3 hours per month supervising overdue invoices — down from over 15 hours before. Everything else is automated: context analysis, personalized follow-ups, contact searches via LinkedIn/Apollo, client communication, and payment tracking.
Is Sanso secure and GDPR-compliant?
Yes. Sanso encrypts all connections, complies with GDPR, and stores only the data necessary to collect payments.
