Short guides per module, answers to the most asked questions and how to write to us.

Guide by module

Invoicing

  1. Create a client under “Clients · Products” (or type their details on the invoice itself).
  2. Press “New invoice”, add the lines and check VAT and income-tax withholding.
  3. Issue the invoice: it gets its serial number, a chained fingerprint and a QR code on the PDF. An issued invoice is no longer edited: it is corrected.
  4. Email it from the invoice itself (you see the message first and you confirm) or download the PDF.

AI Expenses

  1. Upload a photo or a PDF of the invoice or receipt.
  2. Check what it read: amounts, tax ID and date. Doubtful data is flagged.
  3. Confirm the expense: it goes to the expense ledger and to the Taxes calculations.
  4. The Free plan includes 15 documents a month; “Allowance” shows your usage and lets you top up credits.

Collections

  1. Issued invoices appear with their due date and collection status.
  2. Mark each invoice as paid when you get paid.
  3. Client reminders are optional: they are only sent automatically if you switch them on and the server has email configured.

Banking

  1. Import your bank statement as CSV or Norma 43 (we do not connect to your bank).
  2. Match each transaction to an invoice or an expense, or give it a category.
  3. See the 30-day cash forecast.

Taxes

  1. Check the calendar of tax deadlines for the period.
  2. Review the expense ledger and fill in any missing data.
  3. Models 303 and 130 are indicative: they help you prepare the filing, which you or your accountant submit to the Tax Agency.

My money

  1. Create your household and log income and spending; each entry can be shared or personal.
  2. Set a budget per category and see how you are doing.
  3. Invite another person to the household by email (your own email must be verified).

Frequently asked questions

What does the Free plan include?

Invoicing with chained fingerprint and QR, 15 Expense-AI documents a month, up to 120 invoices a year, and My money. Other modules can be bought individually or as a plan, with no lock-in.

Do the invoices comply with Verifactu?

They are designed with the Verifactu chained-fingerprint and QR format. They are not yet certified and are not sent to the Tax Agency.

How do I recover my password?

On “Log in” press “Forgot your password?”. We email you a link that works once and expires in one hour. Changing the password signs out your other sessions.

Why do you ask me to verify my email?

To check the account is yours. You can use FlexiFlow without verifying, but until you do, you cannot buy anything or invite other people. You can resend the link from “My account”.

No email is reaching me

Check your spam folder and that the address in “My account” is right. If the server does not have email sending configured yet, nothing is sent: write to us through the contact form.

Can I take my data with me?

Yes. In “My account” you can download a ZIP with your invoices, clients, expenses, transactions and settings, as JSON and CSV.

How do I delete my account?

In “My account”, “Delete my account”. There is a grace period (14 days by default) to cancel it. Paid subscriptions are cancelled and your accountancy firm is unlinked. Issued invoices are kept because the law requires it; the exact period is pending confirmation by the lawyer.

Is there a lock-in?

No. You pay month to month (or yearly with two months free) and can leave any time; the free modules stay active.
