Comparison
QuietBill vs Substly
Both track SaaS subscriptions. The difference is price and depth: Substly is priced for IT-led European mid-market teams, while QuietBill is built for smaller companies and reads the contract clause itself to compute your real cancellation deadline.
| QuietBill | Substly | |
|---|---|---|
| Entry price | $19/mo flat | €95/mo + €5-6/employee |
| Auto-renewal clause extraction | Yes | Not advertised |
| Real cancellation deadline (not just renewal date) | Yes | Not advertised |
| Email forwarding + Gmail/Outlook + PDF ingest | Yes | Partial |
| Price-increase detection | Yes | Limited |
| Best for | 2-30 employees | European SMB, IT-led |
Where Substly is strong
Substly is a mature, well-designed product with good vendor discovery and a clean UI. If you are an IT-led team in Europe that has already budgeted €95+/mo and a per-seat add-on, it is a reasonable choice.
Where QuietBill wins for small teams
The per-employee pricing is the problem for a sub-15-person company: it turns a flat tool into a growing line item. QuietBill stays flat at $19/mo and does the one thing that actually prevents the expensive mistakes, reading the auto-renewal clause and alerting you against the real cancellation deadline (renewal date minus the notice period), not the renewal date itself.
The honest take
If you have an IT department and want deep vendor management, look at Substly. If you are an ops manager or founder who wants renewal traps caught and a flat, cheap price, QuietBill fits better.
