Questions, answered
How does the free trial work?
You get 7 days to use Kostomer with your real customers. No card is needed to start. You only pay if you decide to keep going.
Can I bring in my existing customers?
Yes. Upload your Excel or CSV list and Kostomer imports your customers and leads in one go, so you don’t start from zero.
Does it really send SMS and email for me?
Yes. Maintenance, rent, payment and follow-up reminders go out by SMS and email automatically on the right day. Your plan includes a monthly allowance of reminders.
Can my staff use it?
Yes. Invite managers, sales reps and installers. Each person only sees what their role needs, and you can see who is handling which customer.
Is my data safe?
Your data is stored securely and only your team can see it, never other businesses on Kostomer. We never sell your data, and subscription payments are handled by Paystack.
Do I need to install anything?
No. Kostomer works in your browser on your phone, tablet or laptop. Sign in from anywhere.
What happens if I stop paying?
Your account pauses, but nothing is deleted. Renew any time and pick up exactly where you left off.
Can I pay monthly?
Yes. Pay monthly, or yearly and get 2 months free. You can cancel any time from your settings.
