Everything Cairos does, grouped by what you need

A whole ERP does not come across well as a list of two hundred tick boxes. This is set out by area, with what each module solves and a link to read it in full. And with what it does not do yet, which is written down as well.

Modules switch on and offVeriFactu on every planYour data leaves with you
Selling and getting paid

Invoicing

The heart of the program, and the one thing on every plan: if you cannot invoice properly, nothing else matters.

Buying and storing

Purchasing and inventory

What comes in through the back door: suppliers, goods and the VAT you deduct.

Expenses and suppliers

Input VAT, IRPF withholding, the attached document and recurring expenses.

Purchase orders

Purchase orders with partial deliveries that move stock, and direct conversion into an expense.

Inventory and warehouses

Stock by warehouse, batches with expiry dates, transfers and stock counts with their value impact.

Products and services

Price, cost, margin, price history, minimum stock and a warning when you sell below cost.

Making sure the money does not run out

Finance and cash flow

Invoicing is not the same as being paid. This is where you see the difference, and how far ahead.

Payments in and reconciliation

Split due dates, partial payments, reminders and bank statements in Norma 43 format.

Cash flow forecast

A balance curve at 30, 60, 90 and 180 days with an overdraft warning, based on what is already committed.

Reports

Sales by month and by customer, purchases by supplier, VAT by quarter, stock and due dates, all downloadable as CSV.

Fixed assets

Monthly depreciation schedules, net book value on the balance sheet, and disposals with the gain or loss they produce.

Closing the quarter

Accounting and tax

The modelos come out calculated from what you have entered, and every box can be opened to see where it came from.

VAT and IRPF forms

303, 390, 347, 349, 111, 115, 130, 180 and 190, broken down box by box.

IGIC and IPSI

The Canary Islands' 420, 425 and 415 and the Ceuta and Melilla forms, with the rates set by each local ordinance.

Books and journal entries

The VAT record book, the general journal, the profit and loss account, the balance sheet and the year-end close.

Tax calendar

The year's deadlines, flagged on the dashboard and exportable to your phone's calendar.

An ERP that switches on piece by piece

The difference between a program that gets used and one that is abandoned in the second month is usually right here: how many screens you see on day one. An autónomo who invoices twenty times a year has no business running into expiry batches or the minute book.

That is why in Cairos modules switch on and off from inside the application itself, and the side menu only shows what you have active. When you sign up, the ones that fit your activity are ticked, and from there you add or remove them whenever you like. Invoices, contacts and VeriFactu cannot be switched off, because without them there is no program.

Some modules drag others along because the data demands it, not on a whim: grants need expenses in order to be evidenced, and a sports club needs its members' register. When you switch one on, the ERP switches on whatever is needed and tells you so.

What Cairos does not do yet

This list matters as much as the one above, and it is here so that you read it before you subscribe and not afterwards:

  • Payroll. It neither calculates nor files it. Staff costs are recorded as an expense.
  • Time tracking and employee records. They are on the Empresa plan and not yet open inside the ERP.
  • Point of sale. There is no till software for the counter.
  • Automatic reading of purchase invoices. The document gets attached; the figures get typed in.
  • Online payment. The portal shows the customer their invoice, but there is no payment gateway.
  • Sending the email from our servers. The message is prepared with its PDF attached and sits in the outbox: the sending provider is still to be connected.
  • Importer from CSV or Excel. Built but not yet open; it comes with the Autónomo plan.
  • API, webhooks and automations. Nor are there integrations with shops or payment gateways.
  • Electronic signature of quotes and contracts.
  • SEPA direct debit batches for customer invoices. They do work for membership fees and donations.
  • Factura-e in XML for public administrations, and TicketBAI for the Basque regional rules.
  • Consolidation across companies. Each company is kept separately, even when they share an account.
  • Barcodes, customer-specific rates, supplier-specific prices and expense approval.
  • Connections to online shops, multi-currency and manufacturing with bills of materials.
  • Filing the modelos with the AEAT. They are calculated and broken down; signing and sending happens at the electronic office, with your own certificate.

Everything above is on the roadmap, and some pieces are half built. What we are not going to do is advertise them as though they were finished.

What is never charged for, whatever happens

Issuing invoices and looking them up, the VeriFactu record, your contacts and the full export of your data are always available, including if you stop paying. Holding someone's invoices hostage so they cannot leave strikes us as indefensible.

Switch on only what you use

Free plan forever, no card needed. And if you outgrow it, you can move up then.

Start with whatever is pressing today

Almost everyone arrives for the invoicing. The rest gets switched on when it is needed.
