Karbon Business is an India-founded fintech, incorporated in 2019, backed by Y Combinator. It serves over 3,000 businesses, known for its flat-fee export receiving and fast settlement, with quite strong support.
For Indian exporters, Karbon gives you a live USD receiving account, plus card acceptance in EUR, GBP and more currencies. Funds convert at a flat ~1% fee and settle directly into your Indian bank account within one to two business days after your payment is captured fully.

Karbon for Indian Freelancers and Exporters
Karbon Business has clear strengths and real gaps still today.
When Karbon makes sense.
You want a flat, low percentage fee with fast settlement. You value auto FIRA on every transaction. You're comfortable starting with a USD-only virtual account for now. You want a dedicated account manager for larger payments.
When Karbon stops making sense.
Your invoices are large and infrequent, so a percentage fee compounds fast. You need multi-currency virtual accounts beyond USD today. You need eBRC confirmed in writing. You want flat-fee predictability regardless of invoice size.
Karbon User Reviews: What Customers Say
Quotes paraphrased from public G2 and Trustpilot reviews from Indian Karbon Business users.
"The fixed charges and transparency of the forex payments have enabled us to control payments accurately."
"I used to dread getting paid from abroad because I never knew what exchange rate the bank would give me. With Karbon, it’s much more transparent."
"My transfers got stuck with banks before; the account manager guided me quite well."
"Tight connection between Karbon and Quickbooks reduced manual entries and sped up our reconciliation process."
"Currency options are still limited to USD mainly, which is a bit of a hassle for us."
"Unprofessional company with misleading, tall claims. They waste your time, collect loads of documents"

Frequently Asked Questions About Karbon
Is Karbon available for businesses in India?
Yes. Karbon Business is an Indian company headquartered in Bengaluru, built specifically for Indian exporters and freelancers. It offers a live USD receiving account today, with EUR, GBP and other currencies accepted via card, and more virtual account currencies reportedly planned. It's backed by Y Combinator and operates via partner-bank arrangements rather than an independent RBI licence.
How much does Karbon charge in India?
Karbon charges a flat fee of roughly 1% on receiving international payments, applied at a live forex rate with no separate markup layered on top. There's no monthly subscription or setup fee found on its public pages. On a $10,000 invoice, that works out to around $100-105 in total fees.
Can I hold USD in my Karbon account in India?
Not by default. Karbon typically settles funds into your Indian bank account within 24-48 hours rather than holding them in foreign currency. That said, Karbon reportedly supports short-term holds of up to 60 days for services proceeds, which can help if you have upcoming dollar expenses to time against.
Does Karbon provide FIRA?
Yes, automatically. Karbon auto-generates FIRA for every transaction at no extra cost, which is one of its clearer strengths. However, it doesn't explicitly confirm automated eBRC generation on its public pages, so exporters who specifically need eBRC for DGFT purposes should verify this directly with Karbon.
Is Karbon safe to use in India?
Karbon is a Y Combinator-backed Indian fintech, founded in 2019, with ISO 27001 certification and partner banks in India. It operates via a partner-bank compliance model rather than holding an independent RBI PA-CB licence of its own, which is worth understanding if regulatory status matters to your decision.
What's the best Karbon alternative for Indian freelancers?
For freelancers collecting mostly in USD who want fast settlement and automatic FIRA, Karbon is a reasonable option. If you need broader multi-currency virtual accounts today or want flat-fee pricing that doesn't scale with invoice size, a platform like Skydo may be a better fit for larger or varied invoices.
Can I send money out of India with Karbon?
Karbon's core receiving product is built for bringing money into India, not sending it out. Karbon does offer a separate outward remittance product with a markup starting at 0.1% for import payments and overseas expenses, which is a different flow from its exporter-focused receiving account.
Should I use Karbon or Skydo?
It depends on your needs. If you mostly collect USD and value fast settlement with automatic FIRA, Karbon's flat 1% fee works well. If you need multiple currencies as native virtual accounts today, or want a flat fee that doesn't scale with invoice size, Skydo's India-first model may suit larger invoices better.
