Invoices on Telegram
Invoices sent on Telegram land in the right client and come out read.
Your client opens the link you send them, taps “Open in Telegram” and from then on sends their invoices there. They get a “Received” and, if needed, a notice: it is not an invoice, it could not be read, it is for another company.

What can be sent to the bot?
A PDF or a photo, up to 15 MB. What it does not accept it says, and it names the type.
The bot accepts a file with its type declared, and it accepts a photo, of which it takes the largest resolution Telegram offers. The types allowed are PDF, JPEG, PNG and WEBP, with a cap of 15 MB.
An iPhone photo sent as a file arrives in HEIC, which cannot be read, so the bot asks for it to be sent as a photo, and Telegram converts it. A file of another type, or a larger one, gets a refusal that names its type or the cap, and it is not downloaded.
Sending receipts on Telegram works the same way as sending an invoice: the photo of a supermarket receipt with several VAT rates is read with its breakdown by rate, base and VAT amount, because the model reads the whole page and not a template per supplier.
A ZIP, on the other hand, is refused: archives and folders are only walked through in the browser, where the ZIP is opened before anything is uploaded.

How does the link get to my client?
One link per client, sent once through WhatsApp or Telegram.
In iCifra you open the client and tap “Send to the client”. The link is copied, shown as a QR code or sent through WhatsApp or Telegram with the message already written.
Your client opens it on their phone: they can upload the photos or PDFs right there, with no account or password, or tap “Open in Telegram” and be connected to that client, so that everything they send to the bot is filed under that client without asking anything.
The link is shown only once and the database keeps only its hash. If it gets lost, “Send again” creates another and the old one stops opening, while anyone already sending through Telegram carries on as before; “Deactivate” stops everything, Telegram included.
The accountant connects their own Telegram from Settings › Your account, and the bot suggests the client from the NIF of each document.

What does the bot reply when it receives a file?
First that it has received it, and then the summary or the reason. No reply is silence.
In a client's Telegram, the reply is “Received. Your accounting firm will review it.” and, if needed, at most two notices: it is a delivery note, a quote, a proforma or a receipt, it cannot be read well, it looks like another company's, or it had already been received. Never a supplier, an amount, a date, or the name of the client or the firm.
In your own Telegram, the bot acknowledges the file and then the summary arrives — supplier, total and date — with a note when the document stays in review or the recipient does not match the client; or “possible duplicate”, saying it has not been posted; or a refusal from the plan, in the chat's language.
The reading is done by AI: an Anthropic model (Claude) reads the PDF or the photo and returns the fields; what it does not settle stays in review until a person approves it.
If the arithmetic does not balance against the printed total, the document stays in review — the summary says so — and the figures are not corrected. If the database fails, the bot replies that nothing has been lost and that you should send it again in a minute, and the real error is logged.
- Three languages
- The bot speaks Spanish, English and Russian. The choice saved in the chat always wins over the language of the Telegram client, and each of the three buttons reads in its own language.
- The commands
- In your own Telegram, “/which” says which clients you can send for, “/unlink” disconnects it from your account and “/language” changes the language. A client's Telegram only sends documents and changes language; it shows nothing about the client or the firm, and the firm disconnects it with “Deactivate the link”. There is no code to type: the link does it all.
- Duplicates
- The same file, sent again to the same client, is not registered again: the bot says it was already there. An invoice that is already there as another file is recognised by its content — same supplier and same number, or same supplier, total and date — and stays as a possible duplicate, not posted.

Where does the file you send end up?
In the client whose link brought it, under “To review”; or, from an accountant’s own Telegram, in the client they confirm with one tap.
What arrives through a client's Telegram is filed straight into that client, under “To review”, and is never approved without a person.
In your own Telegram, if you can open only one client, the file goes into it; if there are several, the bot reads the document once and suggests the client whose NIF it carries, with “Yes” and “Other”, or asks you with a button per client or a search by name or NIF. Before each file is downloaded, it checks that you can still open that client.
Only two kinds of chat file anything: a client's Telegram, connected through its link, and yours, connected in Settings › Your account.
Any other chat — one nobody has connected, or a group — downloads nothing and reads no client: it gets a pointer to what to do, at most three times an hour, and then goes quiet. In a group, ordinary conversation gets no reply. If a client's link is deactivated, their Telegram becomes one more of those chats.

Which plans include the bot, and at what rate does it read?
During the beta there is one plan: the bot comes with it, and it reads up to 500 invoices an hour.
Invoices read per hour are 500 for every firm in the beta. The limit is checked on the server before the model is called, and the window rolls. The bot's door is closed by default: a plan that cannot be resolved is refused, not let through. The database checks the plan again when the client's link is created or renewed, and the bot again on every file.
When the rate is reached, your own Telegram says so in these words: “Invoice reading has reached your plan's rate of 500 an hour. Your documents are saved unread: once the hour has passed, open them in iCifra and press ‘Read again’.
If you need a faster rate, write to us.” Your client does not get that notice: their file is kept, under “To review”. It prints no count because the rate is shared with the assistant and both come out of the same counter.

What does the bot not do?
It does not open ZIPs, it does not post anything by itself, and it lets nobody in just for writing to it.
It does not expand archives: that happens only in the browser. It does not receive email: the two doors are the browser and Telegram. It does not issue invoices and it files nothing with the tax office. And it lets nobody in for writing to it: a chat that is not connected, or that of an accountant whose account is not approved yet, downloads not one byte.
Nor does it post anything on its own. What a client sends always stays “To review”, and only an approved document reaches the Libro Mayor, the figures and the quarter's sheets.
A reading that fails never becomes your fault: the document is kept with its reason. And the reports screen does not show 0,00 € when it could not read the data: it refuses to show figures, because a zero there would look like nothing to declare.
