Before you start, we recommend that you consult the first video or the first guide on the **connection between Plexflow and QuickBooks**, because that step must already be completed. ## Step 1 – Confirm that QuickBooks is connected Go to 👤 **Profile**, then open the **Integrations** tab. You will see, in particular, the **Quickbook company Id**. This identifier is an important element, because it acts as an **access key** between Plexflow and the right QuickBooks account. In other words, this identifier lets Plexflow send the information to the right QuickBooks environment. ## Step 2 – Check the synchronization settings Still in the **Integrations** section, make sure the synchronization settings are properly configured. The important setting to turn on here is **Invoice Sync**. For Plexflow to be able to transfer rent invoices to QuickBooks, this option must be turned on. > **Note:** > The setting related to **Expense sync** corresponds to another part of the process, distinct from rent synchronization. ## Step 3 – Choose the class synchronization mode Plexflow offers **three synchronization options** for classifying invoices in QuickBooks: ### 1. No class No class will be associated with the invoice in QuickBooks. ### 2. Class The invoice will be associated with the **Plexflow property name** as a class in QuickBooks. ### 3. Subclass The **property** will be used as the class and the **unit** will be used as the subclass in QuickBooks. This setting is useful if you want to organize your invoices with more or less precision in your QuickBooks reports. ## Step 4 – Choose the customer name to synchronize The customer-synchronization setting determines the name that will appear on the invoice in QuickBooks. Plexflow offers you **two choices**: - display the name of the primary tenant - display the name of the tenant defined as the payer This lets you adapt the synchronization according to your management method. ## Step 5 – Set the synchronization start date You can then configure a **Sync start date**, if you want to specify one. If you set a date, **only invoices from that date onward will be synchronized**. Earlier invoices will therefore not be transferred to QuickBooks. ## Step 6 – Turn on the properties to synchronize Finally, you must make sure to turn on synchronization for each of the **properties concerned**. Only the properties turned on in this section will be able to send their invoices to QuickBooks. > Without this activation, synchronization will not be able to take place for the property in question. ## Step 7 – Confirm that an invoice is present in Plexflow Once the setup is complete, an invoice must already be present in Plexflow to allow synchronization. If there is currently **no invoice to synchronize**, no transfer will be made to QuickBooks. ## Step 8 – Create a new invoice To allow synchronization, you must first create a new invoice. To do this: 1. Go to the **unit record** 2. Access the **Upcoming Invoices** section 3. Proceed with the **collection of one month of rent** This action will create a new invoice in Plexflow, which can then be synchronized to QuickBooks. ## Step 9 – Locate the transaction identification number Once the month has been collected, a transaction identification number will appear. This number lets you: - locate the transaction - make the link between **Plexflow** and **QuickBooks** - confirm the tracking of the synchronization between the two platforms ## Step 10 – Check the synchronization status In the synchronization section, you can see how many invoices remain to be synchronized, if there are any. Because synchronization usually takes **a few seconds per invoice**, simply **refreshing the page** will generally let you see this number decrease gradually. ## Step 11 – Understand how it works with several collections If **two collections** are made, the system will generate **two distinct identification numbers**. On the QuickBooks side, **two invoices will then be created**, according to the amounts associated with each of the collections. ## Step 12 – Understand the automatic update of amounts It is important to know that if you change: - the **invoice amount** - or the **collection amounts** Plexflow will automatically synchronize these changes with QuickBooks. In other words, if a change is made after the initial creation, the information will be automatically updated on the QuickBooks side. ## To remember For the synchronization of rent invoices to work correctly, you must: - connect Plexflow to the right QuickBooks account - turn on Invoice Sync - configure the right settings - turn on the properties concerned - create an invoice in Plexflow Once these elements are in place, the invoices should synchronize automatically with your QuickBooks account.
