Certificate done.
Invoice drafted.
Link your iCertifi app to Mint Books once. From then on, every certificate you finish turns up in Mint Books as a draft invoice, with your customer, the address and your price already filled in. No retyping, no Friday-night catch-up.
DraftExample figures. You set your own price for each certificate type.
Linked in two minutes.
Then forget about it.
You do this once. After that you just use iCertifi the way you always have.

iCertifi: Settings › Mint Books › Link to Mint Books
Set your prices, then just work
Tell Mint Books what you charge for each certificate type. Every draft invoice arrives with the right amount on it, ready to check and send.
Price it once.
Every invoice arrives priced.
Set a rate for each type of certificate you do. When one comes across from iCertifi, Mint Books puts your price on the draft. You can still change it, add a line for parts or labour, or edit the description before it goes to your customer.
Every invoice starts as a draft. Nothing is sent without you.
Always know
where it's up to.
iCertifi keeps a log of every certificate it has sent to Mint Books, so you can see at a glance what's been invoiced and what needs a look.
- No signal on site? The certificate waits and goes across on its own when you're back online.
- Sent the same one twice? Mint Books spots it by its reference and updates it. No duplicate invoices.
- Got a backlog? Send older certificates in one go: last month, last year, all time or from a date you pick.
Your data stays yours.
Linking iCertifi to Mint Books is built to keep your customers' details safe.
Everything travels over HTTPS, encrypted from your phone to Mint Books.
Your link key is stored in the iPhone and iPad Keychain, not in ordinary app storage.
Every request carries your key. If you remove the link in Mint Books, iCertifi disconnects itself.
Certificates go to your own Mint Books account and nowhere else.
Good questions.
Does it work offline?
Yes. A certificate you finish without signal waits in iCertifi and goes across by itself as soon as you reconnect. There's nothing to remember.
Can I change the invoice before it goes out?
Always. Every certificate creates a draft. Change the price, add line items or edit the description, then send it when you're happy.
What if the same certificate is sent twice?
Mint Books recognises it by its reference number and updates the one it already has. You won't get duplicate invoices, so sending again is always safe.
Can I send certificates from months ago?
Yes. In iCertifi go to Settings, Mint Books, Sync From. Pick Last Month, Last Year, All Time or a date, then tap Sync All.
Does it cost extra?
The link itself costs nothing. Mint Books has its own subscription for invoicing and accounts: 14 days free, then £1 a month for six months, then £9.99 a month on Essential.
