Talk to the person who built it
There is one address, and it reaches Jeel — the person who writes the code and the GST guides. No tier-one queue, no ticket number, no bot asking you to rephrase the question.
- Replies within one working day, Monday to Friday, IST.
- Answered by the person who wrote the code. There is no tier-one queue and no ticket number.
- Bug reports get an acknowledgement and a status, not a canned response.
- Security reports are answered within 24 hours.
What are you writing about?
Every link below opens your mail app with the subject already filled in. They all go to the same inbox — the subject is the routing, and there is no separate billing desk or security team to be routed to. Saying which one it is just gets you a faster answer.
Using Mavoin
Something isn't behaving, an invoice won't come out right, or you can't work out where a setting lives.
Reply: One working day, Mon–Fri IST
GST and export invoicing
Whether Mavoin handles your case — LUT and zero-rated exports, place of supply, SAC codes, an existing invoice series you need to continue.
Reply: One working day, Mon–Fri IST
Billing, refunds and cancelling
Invoices for your own accounts, a refund within the first 14 days, or closing the subscription. Nobody will ask you to justify leaving.
Reply: One working day, Mon–Fri IST
Getting your data out
Export is self-serve — Settings → Data gives you CSV, a full JSON archive or your invoice PDFs, free on every plan. Write in if you want it in a shape that screen doesn't produce, or moved somewhere else.

Security and privacy
Reporting a vulnerability, or a question about where your data sits and who else can touch it. Please don't include the exploit details in the first line — just tell us what you found.
Reply: Within 24 hours
Anything else
Feature requests, a bug you hit in the free tools, writing about Mavoin, or telling us it doesn't fit how you bill — that last one is genuinely useful.

We'll tell you how Mavoin handles a GST case and where the rule comes from, but Mavoin is not a Chartered Accountant service and nothing we send is tax advice for your specific situation. Verify GST specifics with your CA before you rely on them.
What to include
None of this is required — write in with a one-line question if that's what you have. It just tends to turn three emails into one.
- The email address on your Mavoin account, if you have one.
- What you were trying to do, and what happened instead.
- The invoice number if it's about a specific invoice, or a screenshot if it's about a screen.
- Never send your password, and never send full card details. We will never ask for either.
Answers you don't have to wait for
Most of what people email about is already written down, and these pages answer at 2am on a Sunday:
- FAQ — GST compliance, continuing an existing invoice series, USD invoices and INR books, moving over from Zoho.
- Pricing and refunds — what it costs, what the trial includes, how to get your money back.
- Trust — who you're paying, where your data sits, every sub-processor named, and what happens if Mavoin shuts down.
- Security and privacy — how the data is held and what we do and don't collect.
- Changelog — whether the thing you asked for has shipped since you last looked.
- Free invoice generators — raise a GST or export invoice right now, without an account.
What we don't have
- No phone number. One person builds and supports this, and a number nobody could answer reliably is worse than no number at all.
- No live chat and no ticket portal. Nothing to log into, no ticket number to quote back.
- No contact form on this page — deliberately. Email means the thread is in your sent items as well as ours, so you can see exactly what you sent and chase it if we're slow.
Where we are
Mavoin is operated by JEEL SOFTWARE CONSULTANCY, a sole proprietorship in Ahmedabad, Gujarat, India, working IST. That is the party you contract with under the terms, where the full registered address is set out; the entity details and how to verify them are on the trust page.
Not urgent, but worth saying: if you're writing from outside IST, a reply landing “the next working day” may be overnight for you. Include everything you can in the first email and it usually only costs you one night.
