Frequently asked questions
What uptime SLA do you offer?
Custom tier customers get a 99.9% monthly uptime SLA with response-time credits. API and Widget tiers run on the same infrastructure but without a contractual SLA.
Where do your rates and tax rules come from?
We pull directly from RBI (repo rate, lending rates), CBIC (GST), EPFO (PF rates), and the Income Tax Department (slabs, deductions). Updates ship within 24 hours of any rule change.
Can I get custom calculators built?
Yes. Custom tier includes 2 custom calculator formulas per quarter built to your spec, plus priority support for edits and changes.
Is my usage data shared?
No. Business tier data is stored in an isolated Postgres schema per customer. We never share usage patterns or inputs across tenants or with third parties.
Do you offer exclusivity in a vertical?
Exclusivity deals are available for Custom tier customers on a case-by-case basis. Reach out via the form below to discuss terms.
How long does onboarding take?
Widget tier: same day. API tier: 1-3 days for key provisioning and docs walkthrough. Custom tier: 1-3 weeks depending on scope and custom calculators required.
