Can Lyro confirm a customer's VAT or tax ID is genuine?

Yes. Validate Tax ID checks the identifier the customer supplied, Create Tax ID and List Registered Tax IDs record and list the ones you already hold, and Retrieve Tax Jurisdiction confirms which jurisdiction the sale sits in. Calculate Tax Rate then returns the rate that actually applies instead of one someone keyed in by hand.

Can Lyro handle a subscription billing change?

List Recurrings and Retrieve Recurring return the recurring billing on a customer, Update Recurring changes it, Create Recurring sets a new one up, and Delete Recurring stops it. A plan change agreed in a conversation can land on the billing record in the same exchange rather than in a follow-up task.

How does Lyro produce a tax report?

By requesting one and reading it back. Create Report Request queues the report, List Reporting Requests shows what has been asked for, and Retrieve Reporting Request returns a specific one once it is ready. The request and the result are separate calls, so Lyro reports the outcome rather than returning a file the instant it is asked.

What is the difference between an estimate, an invoice, and a receipt here?

Quaderno treats them as separate documents and the toolkit follows that. Create Estimate and Deliver Estimate cover the quote stage, Create Invoice and Deliver Invoice the bill, and Create Receipt and Deliver Receipt the proof of payment. Lyro can produce whichever one the conversation actually calls for instead of forcing everything through an invoice.

How businesses use Quaderno + Lyro

Each card is one request a support team gets, and the Quaderno actions Lyro runs to close it.

Find the invoice a customer is asking about
Lyro locates the customer by the ID their payment processor gave them, lists the invoices on that account, and opens the one in question, so a billing query is answered from the record itself.
Retrieve Contact by Processor IDList InvoicesRetrieve Invoice
Raise the invoice and get it delivered
Lyro creates the invoice from what was agreed, sends it to the customer, and records the payment against it once it clears, so the billing record and the conversation end in the same place.
Create InvoiceDeliver InvoiceRecord Invoice Payment
Get the tax right before anything is sent
Lyro calculates the rate that applies to the sale, validates the tax ID the buyer supplied, and checks which jurisdiction the transaction falls under rather than trusting a figure someone typed.
Calculate Tax RateValidate Tax IDList Tax Jurisdictions
Handle the refund or the chargeback
Lyro pulls the credit note raised against an invoice, assembles the evidence a disputed charge needs, and marks an invoice uncollectible when the money is not coming back.

How it works

Get started in 3 steps

Connect once, then just ask. There is no workflow builder to learn and nothing to maintain — Lyro reads the Quaderno actions it has and picks the ones a request needs.

01
Connect Quaderno
Authorize the Quaderno account your team already uses — one consent screen, no API keys, no mapping tables. Lyro can only do what you granted that account, and you can disconnect it at any time.
02
Tell your agent what you need
Describe the job the way you would hand it to a teammate. Lyro maps it to the Quaderno actions that close it and chains as many as the request needs.
03
Watch it work
The agent runs the actions inside the conversation the customer is already in, so nobody copies data between tabs and your team can take over at any point.
