Introduction
Every booking keeps a change log: the app's record of who saved it, and when. Every time a booking is created or saved, the app writes one row: who did it, when, and the value of each of the booking's fields before and after. You open the log from the booking itself. On the classic booking screen it is the Logs button at the start of the bar of buttons across the top. On the Booking details screen it is the Open log button on the History tab, under All changes to this booking are recorded in the booking log.
The log opens on a screen headed Log with a Back link above the heading. It is one table with a row per save, newest first, and a view icon at the end of each row. Clicking a row opens a second screen, also headed Log, with the details of that one save.
You would come here when:
- A customer says the price or the return date was different when they booked, and you want to see what was changed and by whom.
- A price or date on a booking looks wrong and you want to know when it changed.
- A colleague asks who confirmed or cancelled a booking.
- You want to check what happened to a booking before you call the customer back.
Admin → Logs is gone. The main menu used to have a Logs item under Admin that showed the log of every booking in one place. It was taken out of the menu, so the log can now only be read one booking at a time, from the booking.
Terms used on this screen

| Membertype | Attribute for a plain value, Reference for a link to one other record (a vehicle, a customer), Reference set for a link to several |
How to use
Configuration
There is nothing to set up. The log records automatically, and what it records and the date format are fixed for every company. You cannot switch it off or change it.
Before you start: only a company administrator can open a booking's log. The Logs button and the Open log button do not appear for other accounts. Nobody can change or delete a row in the log, not even a company administrator.
Using the change log
Open the booking, from Bookings → Overview or from wherever you found it. Which booking screen opens depends on your company's Use new booking screen setting; see Find your way around the Booking details screen.
- Open the log. On the classic booking screen, click Logs in the bar of buttons at the top. On the Booking details screen, click the History tab and then Open log. The screen headed Log opens.
- Read the table. It has the columns Date time, Number of changed members, Log type, Reference id and Name (the colleague who saved). Each column has a filter box above it: pick a date above Date time to see the saves of one day, pick Change above Log type, or type part of a name above Name. Date time is in universal time (UTC): in the Netherlands, add one hour in winter and two in summer.
- Open one save. Click the row, or the view icon at the end of it. The details screen shows Reference # and a table with the columns Member, Membertype, Old value and New value, each with its own filter box. Type a field name, such as DropOffDateTime, in the box above Member to find it quickly.
- Go back. Click Back to return to the table, and Back again to return to the booking.
Nothing on these screens changes a booking. You can look as much as you like.
Key details
Every save writes a row, even when nothing changed. Each row lists every field of the booking, changed or not. Number of changed members only counts the fields that really changed, so a row with 0 is a save where nothing changed. You can skip it.
Worked example. On 8 October 2026 a colleague extends booking 14230 by three days. The return date moves from Friday 9 October to Monday 12 October, and the total goes from €1,000.00 to €1,150.50. The log gets one new Change row. In its details:
| Member | Old value | New value |
|---|---|---|
| DropOffDateTime | 10/09/2026 (UTC) | 10/12/2026 (UTC) |
| TotalPriceInclVat | 1E+3 | 1150.5 |
Dates in Old value and New value are written month first, American style, without the time, and in universal time (UTC). Dutch time is one hour ahead of UTC in winter and two hours ahead in summer. Amounts drop the euro sign and trailing zeros. A round amount is written in short scientific form: 1E+3 is €1,000, 5E+2 is €500.
What the log leaves out. Before you rely on the log, know what it cannot show you:
| Not in the log | Why, and where to look instead |
|---|---|
| Anything that is not a booking: customers, vehicles, prices, invoices, payments, settings, users | Only bookings are recorded |
| Changes to a branch | Branch changes are not recorded anywhere. See the Q&A below |
| A change to the time of day only | Dates are stored without the time, so moving a pickup from 09:00 to 15:00 on the same day looks like no change at all |
| Which vehicle, customer or location a booking was linked to | Link fields show only 1 reference or no reference |
| Extras, insurance and drivers | These are kept as separate records, so they are not in the booking's row |
| Quote and Mark as invoiced | These save the booking without a log row; see Correct a booking's details and check its history |
| A booking that has been deleted | Its log goes with it as far as any screen you can open is concerned. See the Q&A below |
What to do next: if the log shows a wrong price or date, put it right on the booking, as described in Correct a booking's details and check its history. If the log shows who made the change, talk to that colleague before you change it back.
Q&A
A booking has gone from Bookings. How do I find out who deleted it? You cannot from any screen at your company any more. The log opens only from the booking, and a deleted booking has no screen. The overview of all bookings' logs that used to be under Admin → Logs is no longer in the menu. Contact RentVisie support with the booking number and the approximate date. To rebuild the booking, create a new one with Create a booking; it gets a new booking number.
Where has Admin → Logs gone? It was taken out of the main menu. Open the booking and use Logs on the classic screen, or History then Open log on the Booking details screen.
Why can't I see the Logs button, or the Open log button, on a booking? The log is for the company administrator role only. Ask a colleague with that role, or ask your administrator to check your role on Add an employee and set their permissions.
How do I find out who changed a branch? You cannot. Branch changes are not recorded, so there is no log for them. The branch screen does not show who last saved it either. Ask the colleagues who hold the company administrator role. Branches are covered on Set up your branches.
Why does a changed pickup time show the same old and new value? The log keeps only the date. A change to the time within the same day shows identical values and is not counted as a change. The booking itself holds the right time, so check it on the booking.
Why is a date in the log one day earlier than on the booking? The values in the log are in universal time. A pickup at 00:30 on 4 October, Dutch summer time, is 22:30 on 3 October in UTC, so the log shows 10/03/2026 (UTC).
Why does an amount read 1E+3? That is €1,000 written in short form. 1.5E+3 is €1,500. Amounts that are not round, such as 1150.5, are written out in full.
Why is Name empty, or showing an account nobody recognises? The row stays even when the colleague's user account is later deleted, but the name goes. A save the app made by itself, or one that came in from outside (such as your website), is shown under the account that made it rather than under a colleague.
Why do the old and new values of a vehicle change both say 1 reference? For a link to another record, the table only says whether a link was there. It counts as a change, so you know the vehicle (Rentals.Booking_Asset) was swapped, but not from which to which. The booking itself shows the vehicle it has now.
Can I delete or correct a wrong row in the log? No. The log cannot be changed by anyone at your company, which is what makes it a reliable record.
