Our support approach
CalcStack is built by a small, focused team that cares deeply about the product and the businesses using it. When you reach out, you are talking to someone who actually builds and maintains the platform , not a scripted support agent. We prioritize clear, honest, and helpful responses over generic templates.
Common reasons to get in touch
- Technical support, embedding issues, calculator configuration, analytics questions, or anything not working as expected.
- Feature requests, want a new calculator type, integration, or builder feature? We plan our roadmap based on real customer feedback.
- Partnership inquiries, agencies, resellers, and integration partners are welcome. We offer co-marketing opportunities and referral arrangements.
- Custom plans, if your needs go beyond the Agency plan, we can build a custom package with direct founder support and bespoke tool development.
- Billing and account, subscription changes, invoices, refund requests, or account deletion.
Response times
We aim to reply within 24 hours on business days. Agency plan customers with priority support receive responses within 2 hours during business hours (9am-6pm EST). For urgent embedding issues affecting live websites, mention "urgent" in your subject line and we will prioritize your request.
You can also email us directly at contact@calcstack.net.
We built CalcStack as a small team that responds to every message personally. When you contact us, you are talking to the people who build the product, not a scripted support queue. That direct connection is how we learn what to build next.

Frequently Asked Questions
What is the fastest way to get help with embedding?

Do you offer custom tool development?
Yes. Beyond the Agency plan we take on custom work: bespoke calculators, scorecards, and decision engines tailored to your industry and data. Contact us with your requirements and we will scope the project.
Can I request a feature?
Absolutely. Many of our most popular features, including PDF reports, dark mode, and webhook integrations, came from customer requests. Describe what you need and we will add it to our roadmap.
