FAQ

Frequently Asked Questions

TrimStack is purpose-built for the US market with comprehensive coverage of American SaaS vendors. Substly has a European focus with limited coverage of US-specific tools and pricing norms. TrimStack's Stack Intelligence Engine is trained on thousands of US SaaS products and can accurately identify, categorize, and flag waste across the tools most US SMBs use every day.

TrimStack auto-detects everything. Upload a CSV from your bank or credit card and our Stack Intelligence Engine automatically identifies every SaaS subscription in your transactions — no manual entry required. Substly's workflow is heavily manual-input-dependent, requiring you to add subscriptions one by one before you can see your full picture.

None. TrimStack is integration-free. You export a CSV from your existing bank, credit card, or accounting tool (QuickBooks, Xero, etc.) and upload it. No OAuth connections, no accounting software integrations, no API keys. Substly requires connecting your accounting software to get full functionality, which adds setup time and a dependency on third-party integrations.

Yes — that's TrimStack's core workflow. A CSV export from your bank or credit card contains all the transaction data TrimStack needs to identify your entire SaaS stack, flag duplicates, calculate waste, and generate a shareable audit report. No integrations, no connections, no waiting. The whole process takes under 5 minutes.
