Multivers integration
Exchanging sales invoices, relations and payments with Multivers
With the Multivers integration, OWNER automatically sends your sales invoices and relations to your Multivers administration, and payments you match to a sales invoice in Multivers automatically come back to OWNER. In this article, you'll read how to set up the integration and how to work with it day to day, and you'll find answers to frequently asked questions.
Prefer to keep everything in OWNER? With OWNER Wallet (expected late 2026), you receive payments in your own bank account in OWNER and they're processed automatically. Read OWNER Wallet or accounting integration: which suits you?

What does the integration do?
| Section | Direction | How often |
|---|---|---|
| Sales invoices | OWNER → Multivers | Every 15 minutes (automatically) or when you submit them |
| Relations (debtors) | OWNER → Multivers | With the first sales invoice, then daily at 12:00 UTC |
| Payment status | Multivers → OWNER | Every 15 minutes |
Before you start
- Access to Multivers with a user who won't be deleted or blocked any time soon; the integration is tied to that user.
- General ledger accounts and VAT codes are already set up in Multivers. You decide which account belongs to which sales item, on your own or together with your accountant.
How to set up the integration
Step 1 – Install Multivers in OWNER
- Go to Settings and, in the environment settings, open Connected apps.
- In the marketplace, choose Multivers and click Install.
- Log in to Multivers with the user from Before you start.
Step 2 – Link owners to administrations
- Assign each owner in OWNER to the right administration in Multivers.
- Multiple owners? Link an extra administration at the top, next to the Multivers logo, via Connect administration.
Step 3 – Choose your settings per administration
In the integration, open Settings at the top.
General tab
| Setting | What it does |
|---|---|
| Sales journal | The sales journal in which the sales invoices are posted. |
| Book invoices automatically | On: all sales invoices for this owner are sent to Multivers automatically. Off: you choose which sales invoices to submit. |
Other tabs
| Tab | What you link here |
|---|---|
| Ledger Accounts | Sales items in OWNER to general ledger accounts in Multivers. Required for every sales item you use in this administration. |
| Vat Codes | VAT codes in OWNER to VAT codes in Multivers. |
Done? Then the integration works right away.
Working with the integration day to day
In the integration, you'll find Invoices at the top. There you work with two overviews:
- Unsynced – sales invoices that haven't been sent to Multivers yet. Select them and click the Play icon to submit them manually.
- Failed – sales invoices that got stuck because of an error message. Check here regularly.
Note: if you turn on Book invoices automatically later, all sales invoices still under Unsynced are also sent to Multivers immediately.
Frequently asked questions
Connecting and setting up
Which other accounting packages can I connect?
Exact Online, AFAS, Twinfield, SnelStart and Multivers. See Which accounting packages can you connect to OWNER?
Exchanging sales invoices
How long does it take for a sales invoice to appear in Multivers?
If Book invoices automatically is on, sales invoices are sent to Multivers every 15 minutes, at fixed times such as 10:00, 10:15, 10:30 and 10:45. If the option is off, you submit them yourself via Invoices → Unsynced and the Play icon.
A sales invoice isn't being exchanged. How do I fix that?
Do you see the message “This sales invoice could not be exchanged with the accounting package”? Open the integration and check under Invoices → Failed which error message is shown. The most common cause is a sales item without a ledger account (see the next question). Still stuck? Send support the exact text of the error message.
Why is a sales invoice stuck because of a missing ledger account?
A sales invoice is only sent to Multivers if every sales item on it is linked to a ledger account.
- Open the integration, click Settings and go to Ledger Accounts.
- Find the sales item without a ledger account and link the right account.
- Submit the sales invoice again via Invoices → Failed.
Tips for creating a sales invoice:
- Always choose a real sales item, such as base rent, with a linked ledger account.
- Is it a credit, refund or down payment? Put that in the title or subject, not in the sales item.
- Manual sales invoice for a rent discount? Choose Rent as the sales item.
Can I create a sales invoice with an invoice date in the past?
No. This is deliberately not supported, because the financial period in your accounting package may already be closed.
Relations and debtors
How often are relations updated in Multivers?
Once a day, at 12:00 UTC (14:00 Dutch summer time, 13:00 winter time). The update goes from OWNER to Multivers, so always change the name, email address and phone number in OWNER.
Why isn't a tenant listed as a debtor in Multivers yet?
A tenant is only created as a debtor with their first sales invoice. You don't need to do anything for this. If creating the debtor fails, check the error message under Invoices → Failed.
Payments
How does a payment from Multivers come back to OWNER?
In Multivers, match the payment to the sales invoice. Within 15 minutes, the integration picks this up and OWNER marks the sales invoice as paid (for a full payment). Only payments matched to the sales invoice in Multivers come back.
Can I record a partial payment or a payment outside Multivers?
You don't record partial payments manually in OWNER; they come in via the integration. Was a sales invoice paid outside OWNER and outside Multivers? Open the sales invoice and choose Actions → Change status → Change payment status → Paid outside OWNER. See also How do I manually mark a sales invoice as paid?
