AI API on a purchase order (India)

Enterprise teams: use unoblox via purchase order, net-30 terms, GST invoicing, and vendor compliance forms. No upfront payment.

PO-based billing for enterprise teams

Large organizations in India need procurement rigor: POs, approval workflows, and vendor documentation. unoblox supports full PO-based billing—no credit cards, no pre-payment, net-30 invoicing from an Indian entity.

How PO billing works

  1. Raise a PO to unoblox (GSTIN shown in your welcome pack and on every invoice) for ₹5,00,000+ per quarter.
  2. Get approved by your finance team (net-30 terms, standard).
  3. Send the PO to billing@unoblox.ai with your vendor onboarding form and MSA.
  4. Use immediately—we'll provision your API key while approvals process.
  5. Receive monthly invoices with token usage, costs, and GST breakdowns for your GL.

Dedicated support for your team

Once you're on a PO, you get:

  • Assigned account manager in India (email + Slack)
  • Quarterly business reviews to optimize spend & model mix
  • Custom usage reports for chargeback to internal teams (cost center allocation)
  • Volume discounts as spend grows

Vendor documentation checklist

Bring these to expedite approval:

  • unoblox's GST registration certificate (GSTIN printed on every invoice)
  • MSA (template provided, ~1 hour to sign)
  • Insurance certificate details, shared on request for your vendor-risk file
  • Indian vendor onboarding form (in place of a W-9, since unoblox is an Indian entity)
  • Authorized signatory list (2 signatories on file)

Frequently asked questions

Q: What's the minimum PO amount?

₹5,00,000 per quarter. Smaller teams use our self-serve billing.

Q: Can we commit to a smaller amount and add more later?

Yes. PO tier is flexible—set a floor, overage is billed at month-end.

Q: How long does MSA negotiation take?

Most enterprises sign in 1–2 weeks. Redlines are rare since we start from a standard, India-drafted SaaS MSA template.

Q: Do you accept three-way invoices (for cost-center billing)?

Yes. Invoice to Company A, consume under Project B, charge back to Department C. We support all three lines on each invoice.

Q: What's your audit trail for cost allocation?

Your dashboard shows usage per API key, tag, and team member. Export CSV monthly for your finance system.

Q: If we underspend, do we lose the committed PO amount?

No. POs are a floor only. You pay for actual usage; the minimum commitment ensures we reserve capacity.
