FAQ

Frequently Asked Questions

Do I need to install anything?
No. Flowstack runs entirely in your browser — nothing to download, nothing to maintain. It works the same on your laptop, tablet or phone.
Can I bring my existing customers and data over?
Yes. Import your customer list from a spreadsheet or CSV in a couple of clicks, and you're ready to start quoting right away — no manual re-entry.
What happens when my free trial ends?
Nothing gets deleted. You automatically drop to the Free plan, keep all your data, and can upgrade again whenever you need more room.
Can my whole team use it together?
Yes, from the Business plan up. Add teammates, assign roles, and everyone sees the same live customer, quote and schedule data — no spreadsheets passed around.
Is my data actually secure?
Everything is encrypted in transit and at rest, backed up automatically, and access is scoped per team member. Your data stays yours — export it anytime.
Can I cancel whenever I want?
Yes, no contracts or notice period. Cancel in one click from your account settings, and export your data before you go if you'd like a copy.
