Prepare GST documents from a chat
Say which month you want. Robnu works out whether that month exists yet, prepares it if it does, and if it does not, tells you the date it will. The refusal is the useful part, because a month that has not been issued cannot be filed from any tool.
Send a request shaped as an instruction, such as prepare GST documents for September, or GST docs for this month for all accounts. Robnu resolves the period, checks the marketplace has issued it, and prepares it. A month not yet issued is refused with the date it becomes available.
- Ask by period in ordinary words: this month, last month, a named month, or last quarter. All four resolve to real month keys.
- A marketplace issues a month after it closes, so this month can only ever mean the most recent issued month, and the reply says which one it used.
- A month that does not exist yet is refused with the date it arrives, rather than returned empty or silently swapped for a different month.
- A quarter is refused as a whole if any month inside it is still unissued, because a part quarter is not a quarter.
- A question about GST is not a request for documents. Questions go to the read only assistant and change nothing.
The awkward thing about marketplace GST is not the arithmetic, it is the calendar. A month's report does not exist the moment the month ends, so half the requests a seller makes in good faith are for something that has not been published. A tool that answers those with an empty file teaches the seller that the tool is broken. A tool that answers with the date tells them something true, and that is the difference this page is about.
Ask for it the way you would say it
The request is ordinary language, not a command code. Prepare GST documents for September. Send GST docs for this month for all accounts. GST documents for last quarter. Each of those resolves to a set of real month keys before anything else happens.
The period words that work are the ones people actually use: this month, last month, a month by name, and last quarter. A named month is read as the most recent occurrence of that month, so asking in January for December means last December rather than a December eleven months away.
The tax and document words are recognised in Hindi and Gujarati script as well as English, and in the romanised forms sellers type on a phone, such as dastavez and kagaz. That matters because this is a request people make in a hurry at the end of a month.
Why this month is not the month you are in
A marketplace closes a month and then issues its report some days later. On Meesho that is the seventh of the following month. So on the third of November, the latest month that exists anywhere is September, and October arrives on the seventh.
Robnu resolves this month to the most recent issued month rather than to the calendar month you are standing in, and the reply names the month it used. Being told September when you said this month is not a mistake, it is the only honest answer, and seeing it in the reply is what stops you filing against a month you have not got.
The alternative designs are both worse. Returning the calendar month gives you an empty document that looks like a product fault. Returning the latest month silently gives you the right file with the wrong label on it, which is the kind of error that is found during an audit rather than during a chat.
The refusal carries the date
Ask for a month that has not been issued and the reply says so, names the month, says it comes out on the seventh of the following month, and tells you the latest month you can actually have. That is four facts, and together they mean you do not have to ask again tomorrow to find out.
A quarter behaves the same way but as a unit. If any month inside the quarter is still unissued, the whole quarter is refused with the name of the month that is holding it up, because three months minus one is not a quarter and a return built from it would be wrong.
This is the same principle the rest of the chat runs on. A refusal that explains itself is a result. A refusal that just says no sends the seller to support, and an empty success sends them to their accountant with the wrong numbers.
A question about GST is not a request for documents
How is GST worked out on my report is a question. Prepare GST documents for September is an instruction. The two take completely different paths, and the test is the shape of the sentence rather than the presence of the word GST.
An instruction needs a verb and a document word, so it reaches the documents flow. Everything else, including every question that merely mentions tax, reaches the read only assistant, which can explain what a deduction is and cannot prepare, send or change anything.
This split is deliberate and it runs throughout the WhatsApp surface. It means asking a curious question at eleven at night cannot start a job, and it means the part of the product that talks has no ability to act.
A period, resolved before anything is prepared
The calendar is the hard part of marketplace GST, not the arithmetic
One account or all of them
A seller with several marketplace accounts can ask for one or for all of them in the same sentence, and asking for all is the common case at the end of a month.
Each account is prepared against the same resolved period, so a set of documents from one request covers one month across every account rather than a different month per account, which is the mistake that happens when you collect them by hand across several tabs.
The documents produced are the same ones the Tax documents screen produces, because it is the same code. Nothing about the chat route makes a different file, so anything you check on the screen is the same fact.
The part of this Robnu does for you
Robnu reads your Amazon account and reconciles every settlement line back to the order that caused it, so a wrong deduction is visible the day it lands.
- Orders, returns, payouts and inventory synced
- Every settlement line matched to its order
- FBA units Amazon has not made good, listed
Where this sits in the rest of your Amazon operation
On Amazon, Robnu syncs your orders, returns, payouts and inventory, reconciles every settlement line back to the order that caused it, lists the FBA units Amazon's own ledger has not made good, flags a return that never came back before the SAFE-T window closes, and scans returns in at your dock. It reads your Amazon account rather than writing to it, so accepting orders and making labels run on AJIO and Meesho today. Related reading:

Questions sellers ask
Because a marketplace issues a month after it closes, on Meesho on the seventh of the following month, so the latest month that exists is usually one or two behind the calendar. Robnu resolves this month to the most recent issued month and names it in the reply, so you can see which one you actually received. Returning the calendar month would hand you an empty file that looks like a fault.
You get a refusal that names the month, says it is issued on the seventh of the following month, and tells you the latest month you can have right now. That is deliberate. An empty document would look like a product failure, and quietly substituting a different month would give you a correct file under the wrong label.
Yes, and it is treated as one unit. If every month in the quarter has been issued you get the quarter. If any single month is still outstanding the whole quarter is refused and the reply names the month that is holding it up, because a quarter missing a month is not a quarter and a return built on it would be wrong.
No. A question goes to the read only assistant, which can explain how something is calculated and has no ability to prepare, send or change anything. Only a sentence shaped as an instruction, with a verb and a document word, reaches the documents flow. The word GST alone is not enough.
Yes, and that is the usual month end request. Every account is prepared against the same resolved period, so one request gives you one month across all accounts rather than a different month for each, which is the error that creeps in when you gather them by hand.
Yes. The chat calls the same code the Tax documents screen calls, so the files are identical and anything you verify on the screen is the same fact. The chat is a different way in, not a different product.

Every Robnu WhatsApp Command, And What Each One Does
The short commands Robnu matches exactly, the modes they open, and the much larger set of things you can simply ask in a sentence. Including which ones change something and which only read.
What A WhatsApp Chat Can And Cannot Change In Your Shop
Running a shop from a chat is only sensible if a chat cannot do something you did not intend. Here is the whole safety model: who the sender must be, which permission each action needs, and why the assistant cannot act at all.
The Daily Order Update, And When It Arrives
Robnu sends one daily summary of your orders to WhatsApp, at a time you choose, with the option of a second. Here is what it carries, the rules the schedule enforces, and why it refuses times that would promise a precision it cannot deliver.
Process Your Marketplace Orders From A WhatsApp Chat
Say process my orders in a WhatsApp chat, pick the account, confirm, and Robnu runs the real accept, label and manifest pipeline. Four gates stand between a tap and a live run, and the assistant is not one of them.
Download A Shipping Label From WhatsApp In One Message
Send an order number, an AWB or a time window and the label PDF arrives in the chat, built to your own label settings. This path only re-downloads a label you already own. It never accepts an order and never mints a new one.
Receive Returns By Sending Codes In A WhatsApp Chat
Say return scan, then send AWB after AWB as the parcels come off the van. Each one is marked received the moment it lands, and shows up everywhere a scan from the web dock does, reports included.
Capture A Claim On WhatsApp, With Photos And Video
Say start claim, describe what happened in any language, and send the AWB photo, the barcode, a photo of what you received and the opening video. Robnu reads each photo and tells you what it read. The draft is finished and submitted from the app.
Someone else created the ASIN for your product
Finding your product already has a page another seller built is normal and usually workable. What you can change, what you cannot, and when a new ASIN is the right answer.
