Can I only add invoices and receipts?

You can add any document to OkiOki that you would like to have instantly available and/or share with your accountant. OkiOki wants to be your one-stop-shop for your financial documents. This includes contracts, agreements, tax statements…

How can I get my outgoing invoices in OkiOki?

There are multiple ways to get your outgoing invoices in OkiOki today:

  • Send them to your clients via your email address linked to OkiOki and they will be picked up automatically.
  • Send them via your favourite invoicing tool and put your linked email address or your personal OkiOki email address in BCC and OkiOki will also pick them up.
  • If you store them somewhere on your cloud storage, then link that cloud storage folder with OkiOki and again, OkiOki will fetch them for you.
  • You can always upload them into OkiOki manually, but hey, who wants to do that if OkiOki can automate it for you.

By the way, by getting your outgoing invoices into OkiOki, she will follow-up on their payment status. Because every unpaid invoice will be missing a transaction. And OkiOki keeps track of that for you.

How does OkiOki send documents to my accountant?

OkiOki converts your documents in real digital invoices (UBL's as they are called) and sends them directly to your accountancy (software) via your personal accountancy email address or FTP.

Can I choose which documents from my mailbox are picked up by OkiOki?

No. OkiOki uses her own intelligence to decide which emails and documents are relevant for your administration. Try her out. You will see that she's quite good in doing this. There are however two ways to 'push' a document to OkiOki:

  • You can put it in a cloud storage folder. Every document in that folder will be picked up by OkiOki.
  • You can send the document to your personal OkiOki email address.

How can I add my credit card statement to OkiOki?

To add your credit card statement to OkiOki, follow these steps:

  1. Go to your menu and select "Upload document" under "Documents"
  2. In your documents, choose the scan of the statement or the PDF you received from the bank.
  3. Add your document. OkiOki will now process your expense report. This may take a few minutes as she will read your document.
  4. Afterwards OkiOki will link the transactions of your expense report to the corresponding documents. If she needs your help, she will let you know via your to-do list.

Important: If you receive your statement on paper, make sure you get a good quality scan. The reading of the different lines requires that the document is perfectly straight on the scan. Also make sure that you scan all pages of your statement for the most correct result.

When does OkiOki send my documents to my accountant?

There are 2 ways in which documents can reach your accountant:

OkiOki forwards it automatically

OkiOki automatically forwards your document to your accountant as soon as she knows it is relevant for accounting purposes. This usually happens in 3 cases:

  • If OkiOki can match a document to a transaction
  • If the document is a sales invoice
  • If OkiOki can recognize that it is a document paid by credit card or direct debit. Then she snoozes the document and forwards it to your accountant.

OkiOki forwards the document after your intervention

This occurs when OkiOki is not sure if a document can be send to your accountant because she can't find a transaction. Then OkiOki will put the document on your task list and it is up to you to indicate if and how that invoice was paid. Once you take one of the following actions, OkiOki will forward the document to your bookkeeper:

  • You set a payment reminder.
  • You indicate that the document was paid by credit card, private money or cash.
  • You snooze a document.

If you delete a document, OkiOki will of course not send it to your accountant.

You can also set up your documents to be sent to your accountant only when you specify it. This is useful if you have an analytical bookkeeping system and you want to indicate to your accountant, for example, to which branch or project this document can be booked.

Can OkiOki help me with invoices I have to download on a supplier portal?

Yes. Lots of suppliers expect you to login to their website to download your invoice. Think about Acerta, Engie, Partena, Proximus, Velocity… OkiOki will relieve you from that hassle as well. If you store your username and password in OkiOki, then she will go and fetch your invoices on their portals. This is one of OkiOki's key strengths today.

Note: OkiOki is built with the most recent security best practices. Credentials you store in OkiOki are only available to the app and to you, even the support team cannot access them.

Can I manually add documents to OkiOki?

Yes you can. There are three ways to do so:

  • You take a picture with the OkiOki app.
  • You upload an existing document (picture/pdf) from your phone or desktop computer.
  • You send a document to your personal OkiOki email address.

Which file types can OkiOki process?

OkiOki can process the following file types: bmp, gif, jpeg, pdf, png and tiff.

Is there a limit in the number of docs I can add?

Depending of your OkiOki license, 25, 70 or 200 documents per month are included as a standard. When you go above that number then there is a cost per document that will be invoiced. But there is no physical limit. You can manage as many documents in OkiOki as you'd like.

However, if your accountant offers you OkiOki, there is never a limit on the number of documents.

If there an upload size limit for documents?

Nope, there is no size limit. But be aware that large files take more time to upload, so they may affect OkiOki's performance.

Can I download my documents?

In OkiOki you can always download your documents in 3 different ways:

Download one specific document

Each document can be downloaded individually using the download feature in the document 'overflow' menu.

Download a set of specific documents

If you want to download a particular set of documents, you do so via your document list. There you can select several documents at once and download them. Of course, you can also search or filter your document list and select and download all resulting documents at once.

Download a complete archive

And finally, you can download all your documents by month, quarter or year using the 'Download Archive' menu.

OkiOki allows you to download your document-archive by month, quarter or year and you will receive the documents in both the PDF and UBL (digital invoice) formats.
