Product

Everything you need to invoice, in one place

Built for self-employed professionals and small businesses that want to invoice quickly and have peace of mind about the rules.

Chained invoicing

Every invoice you issue is cryptographically linked to the previous one — the technical foundation Veri*Factu requires.

All your contacts in one place

Customers and suppliers in one place, ready to invoice without typing a tax ID again.

Series and numbering

Automatic numbering with no gaps, with your own series for invoices and corrective invoices.

PDF with verification QR code

Every invoice includes the tax QR code required by the regulation, so your customer can check it on the Spanish Tax Agency's website.

Bank reconciliation

Upload your bank statement (Norma 43 format) and Kullqi automatically matches payments to your outstanding invoices.

Bookkeeping that keeps itself up to date

Journal, ledger, profit and loss and balance sheet generated automatically from your invoices and expenses — no manual entries.

Online payments

Connect your Stripe account and let your customer pay the invoice in one click, straight to your bank.

Your own email domain

Send invoices to your customers from invoices@yourcompany.com, not from a generic sender.

Connected to Shopify and WooCommerce

Every sale in your online store (Shopify or WooCommerce) or on your Shopify POS automatically creates its Veri*Factu invoice or receipt, with the QR code on the POS screen.

Customers all over the world

Invoices in Spanish or English, exports and sales to EU businesses with their VAT number checked against the European VIES register.

Quotes and pro formas

Send quotes and pro forma invoices as PDFs and turn them into an invoice in one click when your customer confirms.

Expenses without typing

Upload the PDF or a photo of your supplier's invoice and Kullqi fills in the expense for you: supplier, date, amounts and VAT.

How it works

From draft to tamper-proof record

Three steps, in order, without leaving Kullqi.

Step 1

Issue

You create the invoice; Kullqi works out the taxable amounts, VAT and totals for you.

Step 2

Chain

It is sealed with the hash of the previous invoice — tamper-proof from that moment on.

Step 3

Verify

Any party can verify the full chain at any time: you, your customer or the Spanish Tax Agency.
