Can you help us become SOC 2 ready?

Yes. We implement the technical controls — access reviews, audit logging, change management, backups and encryption — and produce the evidence your auditor will request.

Do you support usage-based pricing?

We have built seat-based, tiered and metered billing with Razorpay and Stripe, including proration, dunning, GST/VAT invoices and customer self-service portals.

Who owns the source code and IP?

You do. All source code, designs and documentation are assigned to you on payment of each milestone, and the repository lives in your organisation from day one.

How long does delivery take, and what does it cost?

Every scoped release is planned for delivery within 1–4 weeks, and larger scopes are planned to fit that window rather than stretching the schedule. A fixed quotation follows a free 30-minute scoping call.

Can we negotiate pricing for a long-term engagement?

Yes. Commitments of 3–5 months earn 5% off, 6–11 months 10% off, and 12 months or more 15% off with a 12-month rate lock and a dedicated delivery lead. Invoices are monthly in advance, scaling down or exiting needs 30 days’ written notice, and discounts are recalculated if a commitment is shortened. Everything is negotiable before signing.

How do you handle security and confidentiality?

Every engagement starts with a mutual NDA. Engineers work on managed devices with SSO and MFA, secrets never leave your vault, and production access is granted per person with audit logging.
