You are running several projects at once, and you forget to call off an equipment rental or reclaim a deposit. Small slips like that turn into real money, daily charges that keep running, and deposits that sit locked up. Renting equipment is part of construction. Tracking it does not have to add to the stress.
What an open contract is
An open contract is a rental agreement with no fixed end date. It lets a contractor keep equipment for as long as the job needs it. The rental starts on a specific date, the end date is open-ended, the contract sets a daily rental rate, and a security deposit is usually required. General contractors reach for open contracts because of that flexibility, but the same open end is what causes problems.
The built-in challenges
- No fixed end date. Forget to return the equipment and the daily charges keep accruing.
- Busy schedules. A contractor juggling many tasks can easily forget to call off a rental.
- Unclaimed deposits. Forgetting to return equipment also means forgetting to reclaim the deposit, which ties up funds.
What it costs to forget to call off a rental
An untracked open rental has knock-on effects across the project:
- Ongoing costs. With no fixed end date, charges keep adding up until the equipment is returned or the rental is called off.
- Cash flow problems. Unclaimed deposits mean less money available for other project needs.
- Financial confusion. Without a system, tracking multiple rentals gets messy.
- Strained vendor relationships. Late payments and unresolved rentals damage relationships with equipment suppliers.
- Project delays. Mishandled finances disrupt project schedules.
- Wasted resources. Returning equipment late leads to inefficient use and higher costs.
- Reputational damage. A pattern of financial mistakes makes it harder to win new contracts.
- Operational disruptions. Poor financial management disrupts project progress and resource use.
- More administrative work. Fixing financial problems pulls you away from more important tasks.
How APARBooks keeps equipment rentals under control
APARBooks handles the two failure points directly. You can set a future time for APARBooks to email the general contractor a reminder, so a rental gets called off and a deposit gets reclaimed before charges pile up. And you can record a deposit the moment it is returned, which keeps the rental records accurate and current.


What you get
- Timely notifications. Reminders make sure rentals are called off on time, which prevents unnecessary daily charges, and automated email keeps you on track.
- Deposit management. Recording deposits as they are returned keeps records accurate, and reclaiming them quickly frees up cash for other project needs.
- Centralized tracking. A dashboard shows every open rental, its status, and its due date, with all rental and deposit information in one place. This ties into broader expense management across the project.
Frequently Asked Questions
Why do open-ended equipment rentals cost contractors money?
An open contract has no fixed end date, so the daily rate keeps charging until the equipment is returned or the rental is called off. If the contractor forgets, the charges run and the security deposit stays tied up.
How can a contractor avoid forgetting to call off a rental?
APARBooks lets you set a future date for an email reminder, so the rental is called off and the deposit reclaimed on time rather than being missed on a busy schedule.
How does APARBooks handle security deposits on equipment rentals?
You record a deposit in APARBooks the moment it is returned, which keeps the financial records accurate and puts the funds back into circulation for other project needs.
