Invoice, keep the books, and reach the 20th with your taxes already worked out
Cairos is the Spanish ERP for autónomos (registered self-employed workers), small businesses and non-profit organisations. Invoices with VeriFactu, expenses, inventory, cash flow, and the AEAT tax forms already worked out from what you have entered over the quarter.
The quarter does not get complicated because of the accounting.
It gets complicated because of the loose data.
Invoices in one program, expenses in a folder, the bank in another tab and the spreadsheet only you understand. When the 20th comes round — the day the quarterly returns are due — it all has to be pulled together by hand, and that is where the hours go and the mistakes appear.
How it is normally done
- Invoices in one program, expenses in another and the VAT in a spreadsheet.
- Modelo 303 gets worked out by hand, and nobody knows where each box came from.
- Deductible expenses turn up in March, when they are no longer any use for the quarter.
- Nobody notices that invoicing a German client means you have to file a modelo 036.
- If your accountant asks about an invoice from two years ago, you have to go and find it.
- And now VeriFactu on top of it.
With Cairos
- One single database: what you invoice and what you spend feed the same set of books.
- Modelo 303 comes out calculated, showing which invoice goes into each box.
- Expenses go in as they happen, and the result for the quarter is always up to date.
- The ERP flags the modelo 036, because it is the only thing that knows you have invoiced abroad.
- Everything is stored, searchable and exportable, with the PDF attached.
- VeriFactu included from day one, on the free plan too.
One module for each thing your business does
You switch on only the ones you need. An autónomo invoicing for services sees four screens; a garage with a warehouse sees its own. Nobody has to learn a whole program in order to issue an invoice.
Invoicing with VeriFactu
Invoices, quotes, delivery notes and pro forma invoices with your own series, your own numbering and your own design. Every invoice generates its chained record and its QR code, and the customer views and downloads it from a private link, with no account and no password.
Accounting
Record books, journal entries and annual accounts, without having to know accounting to use it.
AEAT tax forms
303, 390, 347, 349, 111, 115, 130, 180, 182, 200, 036 and 720, worked out from your own data.
Inventory
Stock by warehouse, batches with expiry dates, transfers and stock counts.
Cash flow
Due dates, reconciliation against the bank statement and a 90-day cash forecast.
Time tracking Coming soon
The working time record the law requires, on the Empresa plan. It is not open inside the ERP yet: its own page sets out what exists today and what is still missing.
CRM and projects
Opportunities, and what each project costs and brings in.
And what no general-purpose program gives you
A members' register with fees collected by direct debit and its SEPA file, donations with their certificate and modelo 182, the application of a cooperative's surplus under your region's own law, the VAT exemption on a sports club's membership fees, grants and the evidence they require, the equivalence surcharge, IGIC in the Canary Islands and IPSI in Ceuta and Melilla.
VeriFactu is not a paid feature. It is the law.
The Regulation on computerised invoicing systems requires every invoice to leave behind a record that cannot be altered and that is chained to the one before it. Cairos does this on its own, on every plan, the free one included.
- An issue record and a cancellation record for every document
- Chained SHA-256 hash: if someone touches an old invoice, it shows
- QR code and the compulsory legend on the PDF
- Submission to the Spanish Tax Agency in VERI*FACTU mode, with your own certificate
The quarter comes out of what you have already entered
There is nothing to type in again. Every modelo is worked out from the invoices and expenses for the period, and you can open any box to see exactly which documents make it up. Filing it is still down to you or your accountant, at the AEAT's electronic office.
VAT
Quarterly modelo 303 and annual modelo 390, with the pro rata rule, capital goods and adjustments.
Withholdings
Modelo 111 for employment and professional withholdings, modelo 115 for rent, and their annual summaries, 190 and 180.
IRPF for the self-employed
Modelo 130 with the gastos de difícil justificación (the flat hard-to-evidence deduction) and accumulated depreciation.
Operations
Modelo 347 for transactions with third parties and modelo 349 for intra-Community ones, with a warning when a modelo 036 is due.
Your business does not invoice like the one next door
A building site does not invoice like a consulting room, and an association is not taxed like an S.L. Each page sets out what genuinely changes in each case, not the same list of features with a different photo on top.
Self-employed
Modelo 130 or 131, deductible expenses and the month's social security contribution.
Small businesses
Several users, permissions, inventory and Corporation Tax.
Accountants and tax advisers
Several companies from a single account, and figures that arrive already reconciled.
Hospitality
Till receipts, reduced VAT rates, staff and daily suppliers.
Construction
Reverse charge, stage payment certificates and withholdings.
Associations and foundations
Membership fees, donations, grants and Law 49/2002.
This is what the quarter looks like when it is up to date
This is not a mock-up: it is the program's own screen. The dashboard tells you what you have invoiced, what you are owed and what is coming at you, before the 20th arrives.
Look inside without committing to anything
The free account asks for no card and does not expire. Issue a couple of test invoices and you will see how the program behaves with your own data.
From nothing to your first invoice in ten minutes
No installation, no consultant, and no sales call before you can try it.
Create the account
With an email address. No card, no lock-in.
Enter your tax details
NIF, address and the series you number with. Two minutes.
Bring what you already have
Contacts and products, typed in as you go. Importing from CSV or Excel is on the way.
Invoice
With its VeriFactu QR code and its chained record from the very first one.
A small team, in Spain, that picks up the phone
Cairos is not a fund's portfolio product, nor anybody's Spanish subsidiary. We build it here, we maintain it here, and we handle support ourselves, in Spanish and without escalation tiers.
There is a bad side to that and it is worth saying: we are new, we do not have twenty integrations or ten years behind us. And a good side: when you write in, the person who answers has written the code.
- Servers in the European Union, backed up daily.
- Your data exports whole, from your own account.
- No lock-in: if it is not working, you leave and you take everything with you.
