How to judge rental software
There is no single best platform. There is a best fit for your season, your risk and your volume — and five questions that settle it.
No monthly subscription to start — two plans lower your costs as you grow.
The short answer
Judge rental software on five things: how it prices you across a full year, whether deposits are held rather than charged, whether damage evidence is built in, how payments are handled, and whether availability understands turnaround time. Feature lists rarely differ enough to matter; these five do.
Almost every rental platform can take a booking. What separates them is what happens either side of it — and how the bill behaves in the months you are closed.
What actually differs
| Question | Why it matters | What good looks like |
|---|---|---|
| How am I billed across a year? | Rental is seasonal. A flat monthly fee charges you the same in your closed months as your peak ones. | Cost that follows revenue, or a subscription low enough that four dead months do not hurt. |
| Are deposits held or charged? | A charged-and-refunded deposit costs two transaction fees and leaves the customer out of pocket for days. | Pre-authorisation that holds without moving money and releases automatically. |
| Is damage evidence built in? | Most disputes are about condition. Without dated photographs you lose either the money or the customer. | A checklist and photographs at both ends, attached to the booking. |
| Who handles payments? | A separate payment contract means deposits, refunds and payouts live in a different system from the booking. | Payments in the same flow, whitelabel, with cost shown as its own line. |
| Does availability know turnaround? | Most double bookings come from an object being bookable the instant it is due back. | Buffer time per category, set by you. |
Subscription or commission?
This is the decision that changes your bill the most, and it turns on one number: how evenly your bookings are spread across the year.
If you take a steady, high volume every month, a flat subscription usually works out cheaper — above a certain number of bookings, a percentage costs more than a fixed fee. If your revenue arrives in a burst and you are quiet or closed for months at a time, commission wins, because a closed month costs you nothing.
reservationbay sits on both sides of that trade rather than picking one: Flex is €0 a month at 2.95% per booking, Pro is €149 a month at 0%, with Growth between them. Work it out against your own numbers — take last year's bookings, apply each plan, and compare the annual totals.
Be honest about the boundaries
reservationbay is a strong fit in some cases and a weak one in others.
- Strong fit: seasonal rental, where four quiet months make a subscription painful.
- Strong fit: businesses where deposits and damage disputes are a real cost.
- Strong fit: rental businesses with no website, via the SitePack integration.
- Weaker fit: if a competitor's flat fee undercuts Pro at €149 a month with 0% commission, which is worth checking at very high volume.
- Weaker fit: anyone who needs a mature public API today — ours is still in development.
- Weaker fit: branches we have not shipped yet, like self-storage and subscription rental.

Frequently asked questions
Which rental software is best?
There is no single answer, and any vendor who gives you one is selling. The right platform depends on how seasonal your revenue is, how much deposit and damage risk you carry, and whether you already have a website that can take bookings.
How do I compare pricing models fairly?
Take last year's actual bookings, month by month, and apply both models to them. A subscription looks cheap in August and expensive in January; a commission does the opposite. Only the annual total tells you anything.
What do people most often get wrong when choosing?
Comparing feature lists. Nearly every platform can take a booking and show a calendar. The differences that cost you money are in deposits, damage evidence, turnaround time and how the bill behaves out of season.
Should I trust a vendor's comparison page?
Only as far as it names cases where the other platform wins. Ours do. Treat the rest as informed but interested, and check anything decisive with the other vendor.
