What Regulo actually does
Invoices and credit notes are generated automatically for every order, with sequential numbering, your branding, logo and sender address, and delivery to the customer by email and through their account. Orders from the online store, from connected marketplaces and from Shopify POS all flow into the same document stream, which matters because mixed-channel sellers otherwise end up invoicing from two systems. Documents are produced in Factur-X, the French hybrid format that carries structured XML inside the PDF.
On the accounting side the app exports the FEC file in Excel for your accountant, and lists compatibility with Pennylane, Sage, Cegid, ACD and MyUnisoft. The dashboard reports revenue excluding tax, VAT collected, order and document counts, and breaks revenue down by country and by shop, which is useful if you run more than one storefront, multi-store and multi-entity support appears from the $199 tier. French and EU VAT rules are handled including reduced rates, and the awkward cases that generate credit notes rather than invoices, refunds, exchanges, gift cards and return fees, are covered explicitly.

Before you spend trial time
- Count your monthly invoices plus credit notes, not orders, and match that to a tier before the trial ends
- Generate a document for each awkward case you actually have: a refund, an exchange, a gift card and a return fee
- Send a test FEC export to your accountant and have them load it into your ledger before you commit
- Check the invoice template carries your legal entity details, VAT number and sequential numbering correctly
- Confirm marketplace and POS orders appear in the same document stream as online store orders
- If nobody on your team reads French, have whoever will maintain it try the configuration during the trial

Closing take
For a store with French VAT obligations this does the unglamorous work properly: compliant documents in the right format, generated for every channel, with an export your accountant can use without re-keying anything.
Judge it on two numbers. Your real monthly document count, including credit notes, decides which tier you are on and whether overage will bite. And your team’s French decides whether day-to-day administration is comfortable or constant translation. Get both right and this is a cheap solution to an expensive problem; confirm your actual e-invoicing obligations and dates with your accountant rather than any app’s marketing.

Frequently asked questions
Is Regulo available in English?
No. The listing states the app is not translated into English and the interface is French only. The documents it produces follow French and EU standards, so a French accountant will be comfortable with it, but an English-speaking team will find configuration harder.
What is Factur-X?
The French hybrid electronic invoice format: a PDF that carries structured XML data inside it, so the same file is readable by a person and by accounting software. Regulo generates invoices in this format automatically.
How is Regulo priced?
By document volume. $9 a month covers 100 invoices or credit notes, $39 covers 500, $99 covers 2,000, $199 covers 10,000 and $399 covers 25,000. Documents above the allowance are charged individually, from $0.20 down to $0.04 depending on tier.
Does it handle refunds and credit notes?
Yes. Refunds, exchanges, gift cards and return fees are handled explicitly, along with reduced VAT rates. Remember that a refund creates a second document, which counts towards your monthly allowance.
Will my accountant be able to use the exports?
It produces the FEC French tax audit file in Excel and names compatibility with Pennylane, Sage, Cegid, ACD and MyUnisoft. Send a test export to your accountant during the 14-day trial rather than at year end.
Is French e-invoicing mandatory?
The reform has been through several timetable changes, so confirm your own obligations and dates with your accountant rather than relying on any app’s marketing. What is clear is that Factur-X is the format French rules are built around, and this app produces it.
