Important information
This feature is available for:
Bookings created from 5 May 2025 onwards. Older invoices cannot be managed using this method.
Sites with Invoice Enhancements.
Find out more about this feature in our support article: Invoice Enhancements overview.
Benefits of this feature
Enabling access to Room Billing after checkout introduces several operational advantages:
Improved post-stay service: Users can amend invoices after a guest has checked out, ensuring accurate billing adjustments.
Enhanced billing accuracy: Users can create invoices, credits and corrections without needing to undo checkout.
Better cashflow management: Ensures timely adjustments, reducing outstanding balances created by checkout errors.
Post-stay upsell opportunities: Allows additional services or charges to be added after checkout.
Audit trail for record keeping: Captures all post-checkout billing actions for accountability.
Amend room billing before check-out
If a billing mistake is found while the booking is still resident, you can amend the bill within room billing.
If the Invoice has been finalised, you can select Reinstate Invoice, which:
Creates a credit or reversed bill split.
Creates a new bill split and recreates all of the previous postings.
Allows you to amend charges as required.
Amend billing after check-out
This is now possible without having to un-do a check out.
To correct a billing mistake after the guest has been checked out, follow to steps below:
Open the required reservations invoice:
Navigate to Accounting, Reports and then select Invoice reprint. Use the filters to find the invoice and then select Room Billing.
Or, within the bedroom reservation, select the 3‑dot menu, then select Room Billing.
Within the Room Billing, click to Reinstate Invoice.
Make the required changes, such as:
Add new postings or charges.
Reinstate a split if you need to perform invoice corrections.
Amend the Billing Address.
Assign to a ledger account.
Once the changes are complete and the bill split shows a zero balance, select Finalise to close billing.
⚠️Important: Finalise not only completes the bill but also ensures the reporting for post-stay room billing amendments is correctly updated.
Reporting for post-stay room billing amendments
When you access Room Billing and begin making post-stay amendments, the booking will automatically appear in the relevant financial reports:
Room Balances report: The booking is listed under the new Checked-out Bedroom Balances and Credit Limits section. This section displays all non-resident bookings with open balances reactivated splits, ensuring clear visibility of any post-checkout billing activity.
In-house CFWD figures: Any open balances will also be included in the period-end In-house CFWD totals until the invoice is finalised.
Once you complete all required amendments in Room Billing, selecting Finalise will automatically:
Remove the booking’s balance from the Room Balances report.
Remove the balance from the EOD CFWD section.
Troubleshooting
Why can’t I access Room Billing after checkout for some bookings? This is only available for bookings created since 5 May 2025. If the booking was made prior to this date – you will need to use our article: Correct an invoice passed the check out date.
If I finalise the bill and then spot another mistake, what should I do? You can follow the same steps in this article to make further amendments.
How can i view all post-stay room billing amendments? The booking reference will not be listed within the Room Billing screen drop-down. You will need to access via the Reservation each time. You can see a list of open room billing for checked-out reservations by navigating to Accounting, then within Reports select Room Balances. Scroll to the bottom of the report to the section entitled Checked-out Bedroom Balances and Credit Limits.
Why is a Reservation still showing on Checked-out Bedroom Balances and Credit Limits when the balance is 0.00? Checked-out balances show for any invoices that have not been finalised. You can finalise the invoice to remove it from this list of outstanding room balances, by navigating to the reservations room invoice reprint, then selecting Finalise.
We do not have Invoice Enhancements – what does this mean for us? This feature is not available for sites in Thailand that are using Document Tracking. For sites in other regions, please read our support article on Invoice Enhancements and how to activate this feature.
What user permissions or audit logs are there for post-stay billing changes? Permissions/role requirements: Room Billing; Room billing - Amend; Invoice Reprint; Regenerate Invoice. You can see within Reservation Logs that the Finalise button shows as “Checked out” within the logs.
I cannot use the feature because the “for date” on the invoice will be incorrect. When the transaction is posted:
The Posting Date is set to the current accounting period.
The For Date remains the original date used in the initial postings.
I cannot reinstate the invoice, the button is greyed out. When you hover over the button, Rezlynx displays the reason why the action is unavailable. In most cases, this occurs because one of the following has happened:
A credit note has been allocated to the invoice in Aged Debtors.
A deposit has been invoiced to the ledger against the invoice.
To reinstate the invoice:
Go to Aged Debtors.
Locate the company and the affected invoice.
Unallocate the credit note, or related allocation, from the invoice.
Once the allocation is removed, return to the invoice — the Reinstate button will become available.
When a reversed split is created, Rezlynx automatically allocates the reversed split to the original invoice. This allocation happens automatically; the user does not need to manually allocate it in Aged Debtors.
