# I didn't charge the correct VAT! / I now have to charge VAT

Ouch, you followed the billing process perfectly fine, everything went smoothly, but suddenly you realize that:
- you now need to invoice VAT and it applies to the invoice you have already issued
- you invoiced the wrong VAT amount (10% instead of 20% for example)
- you charged VAT but did not indicate it on the site
and now it's panic time.

It happens, grab a hot (or cold, or alcoholic, no judgement) drink and follow these simple steps:

# 1/ Provide all the necessary information in your administrative profile

Do it now or you will forget.

###### a/ How do I do that?
Simply by indicating your VAT number in the VAT number field and then specifying your VAT rate, easy!

###### b/ I don't have my number yet!
We have taken this into account. You cannot yet modify your profile, but for the next invoice at the end of the project/month, you can still add a VAT rate without indicating the number.
Remember to update your profile as soon as you have your number!

# 2/ What about invoices already issued?

Do not cancel them (otherwise it will delay clients' payment deadlines even further).

You will have to send us this little accounting monument called a VAT catch-up invoice to the address [finance@acracy.co](mailto:finance@acracy.co):

In short, it is a corrective invoice for the first invoice that must:
- indicate "VAT catch-up invoice not invoiced on invoice XXXX" (this is the reference of the invoice in question, which you can find in your "Invoices" space on the site)
- indicate the TOTAL amount of the project, including VAT as if you were invoicing correctly for the first time
- then deduct what has already been invoiced (i.e. the project's net amount)
- to leave only the VAT amount

So for example, you invoiced a project of 1000€ net via the site, and you need to catch up on 20% VAT (i.e. 200€).

Your invoice must contain this information:
__VAT catch-up invoice not invoiced on invoice XXXX__
_Project YYY for ZZ days = **1000€**_
_VAT (20%) = **200€**_
_Already invoiced = **-1000€**_
_Amount to pay = **200€**_

Yes, it's less complicated than it sounds.

Send all this to [finance@acracy.co](mailto:finance@acracy.co) and hop, let's forget about it and start fresh.
