As published, GST e-invoicing through the Invoice Registration Portal (IRP) is mandatory for GST-registered businesses whose aggregate annual turnover exceeded ₹5 crore in any financial year since 2017-18, with that threshold effective from 1 August 2023. This threshold has been lowered several times since the mandate began, so it should not be treated as fixed — confirm the current figure with your adviser rather than relying on this page alone. Separately, a 30-day IRN (Invoice Reference Number) reporting window applies to businesses with turnover of ₹10 crore or more, effective from 1 April 2025 (as published — confirm current requirements with your adviser).
LATYNEX Digital builds the workflow around the invoice data your IRP-integrated e-invoicing provider needs. This page covers it for Mumbai businesses. The general service is at Workflow Automation & Systems Integration, and the market overview is at LATYNEX Digital for businesses in Mumbai. Delivery is in English, and this page names no client.
Typical industries
- Small and mid-sized retailers and service businesses
- Wholesalers and distributors invoicing B2B customers
- Manufacturers billing domestic and export customers
- Finance and back-office teams preparing invoice data
- Businesses newly in scope after a lowered turnover threshold, or approaching the 30-day IRN window
Common lead-handling problems
- Sales recorded in a spreadsheet or ERP export, then re-keyed for invoicing
- Invoice fields split across several tools with no single IRP-ready source
- No record of which invoices the IRP rejected, or why
- A missing field found only when an IRP-integrated provider rejects a batch
- No internal owner for tracking the 30-day IRN reporting window where it applies
Direct answer
If your Mumbai business's turnover puts it inside the current GST e-invoicing threshold, LATYNEX can build a workflow that turns your existing sales or billing records into one clean invoice data set, checks it against the fields your IRP-integrated provider expects, and gives every rejected or exception invoice an owner before it is resubmitted — including tracking the 30-day IRN reporting window where it applies.
Why the global page and the Mumbai hub are not enough
The global Workflow Automation & Systems Integration page has no GST e-invoicing threshold to design against, and the Mumbai hub is broad discovery for the market. Here the design point is that the turnover threshold has moved down repeatedly since the mandate began and a separate 30-day reporting window applies above ₹10 crore, so the invoice data has to be checked against whichever rule currently applies to your business, not a threshold from an earlier year.
What we configure and build
The work sits before your IRP-integrated e-invoicing provider, not in place of it.
- An invoice data workflow pulling from your existing sales, billing or ERP records
- Field checks against the IRP structure your e-invoicing provider confirms
- A queue for rejected or exception invoices, with an owner and a status
- A tracking view for the 30-day IRN reporting window, where your turnover puts you in scope
- A log of what was prepared, when, and the outcome, plus a written handover
What stays with you and your IRP-integrated provider
Reporting to the Invoice Registration Portal, obtaining the IRN and QR code, and any dealings with the GST authorities stay with your accountant or IRP-integrated e-invoicing provider. Whether a given invoice meets the current GST e-invoicing threshold or reporting window is for you and your adviser; we prepare and check the underlying data, we do not report it to the IRP.
What needs API support or custom scope
LATYNEX claims no IRP integration and no GST-authority accreditation. Any connection to your IRP-integrated provider, ERP or accounting system is scoped per project through the documented API or export format if access is permitted, after technical review.
What we do not do, and where LATYNEX is not the right fit
LATYNEX does not give tax or legal advice, does not connect directly to the IRP, does not say an invoice is compliant, and holds no GST-authority accreditation. It has no Mumbai office or named clients, and delivery is in English only. If you already run an ERP with a working IRP connector, this page is not for you.
How delivery actually works
LATYNEX Digital has no office in Mumbai and does not claim one. We work with Mumbai businesses remotely, over video calls and written updates, in English, with the same team and process as in every other market.
Questions
Do you have an office in Mumbai?+
No. We work with businesses in Mumbai remotely, over video calls and written updates, in English, and we do not imply a local presence.
Do you connect to the IRP or report invoices for us?+
No. Reporting to the Invoice Registration Portal and obtaining the IRN stay with your accountant or IRP-integrated e-invoicing provider. We prepare and check the invoice data beforehand.
What is the current GST e-invoicing turnover threshold?+
As published, the threshold is aggregate annual turnover exceeding ₹5 crore in any financial year since 2017-18, effective from 1 August 2023. This figure has moved down several times since the mandate began, so confirm the current threshold with your adviser rather than treating any figure, including this one, as permanent.
What is the 30-day IRN reporting rule?+
As published, businesses with turnover of ₹10 crore or more must report B2B invoices to the IRP within 30 days of the invoice date, effective from 1 April 2025. Confirm whether it applies to your business with your adviser.
Does this make our invoicing compliant?+
No. We give no tax or legal advice and cannot say your invoicing meets requirements. Confirm current requirements with your adviser; we build to the data set they and your e-invoicing provider specify.
How are you invoiced, and in what currency?+
In EUR, by Latynex Trade OÜ, a company registered in Estonia (EU). Tax treatment for a client in India is confirmed on the quote, and we do not give tax advice.
