A deposit safe (or drop safe) lets staff put cash into a safe without being able to take it out. Notes or sealed envelopes go through a slot, chute, drawer or rotary hopper into a locked compartment that only a manager or cash-in-transit crew can open. Any business that builds up cash in its tills during the day, such as a pub, service station, supermarket or takeaway, benefits from one.
In this article we explain the main deposit mechanisms, how they support dual control and cash collection, and how to choose the right size and rating. It is part of our complete guide to commercial safes, which covers every type of business safe.
How a deposit safe works
Every deposit safe has two parts: a deposit opening that anyone on shift can use, and a main door that only authorised people can open. The trick is in the deposit opening. It must accept cash easily while stopping anyone from reaching or “fishing” items back out.
The result is a simple separation of duties. Counter staff can move cash out of the register as soon as it builds up, but they cannot get it back. That removes the temptation for internal theft and makes a hold-up less rewarding, because staff genuinely cannot open the safe.
The main deposit mechanisms
Top or front slot with anti-fish baffle
The simplest design is a slot in the top or front of the safe with an internal baffle that blocks hands, tools and wires. The Stronghold Drop Safe Size 1 uses an anti-fishing baffle, and the CMI Commerce Safe Front Deposit range uses an anti-fish deposit chute.
Rotary or hopper deposit
A rotary deposit has a drum or hopper. You place the envelope in, turn the handle, and the drum drops it into the safe while closing off the opening. At no point is there an open path into the safe body. The CMI Rotary Deposit Safe FL1 and FL2 use this design.
Drawer or trap deposit
A drawer deposit works like a pull-out tray. You open the drawer, place the cash in, and closing the drawer tips it into the safe. The Chubb Mini Banker Drawer Trap MKII and the CMI CashGuard CG1 both use deposit drawers.
Front or rear deposit on larger safes
Heavier commercial safes can have the deposit on the front, or on the rear so it can be fed through a wall from another room. In our range, the CMI Commerce Safe comes in both front deposit versions such as the COM1 and rear deposit versions, with a listed cash rating of $40,001 to $60,000.
Dual control, time delay and cash collection
A deposit safe is most effective when the lock arrangement matches your cash procedures.
- Dual control: safes such as the Platinum Safes Manager DM2KK with dual key locking need two keys, held by two different people, to open the main door.
- Time delay: the lock waits a set time after the correct code before opening. Victoria Police recommends safes with a post-feed, time-delay lock and dye device in its robbery prevention advice for businesses.
- Separate compartments: some safes split a deposit-only section from a float or change section. The CMI CashGuard CG1 has a dual-key internal cash management compartment and a roll-out change drawer with time-delay latching.
- Multi-user and audit locks: advanced electronic locks record who opened the safe and when. Our post on the Dormakaba Axessor multi-user safe lock shows features such as one-time codes used by cash collection services.
If you use a cash-in-transit service, ask them what lock arrangement they work with before you buy. Some services supply or specify their own locking system.
Which businesses need a deposit safe?
Any business where cash builds up at the counter faster than it can be banked. Common examples include:
- Service stations and convenience stores: long hours, small teams and late-night trading.
- Supermarkets and larger retailers: several registers feeding one safe.
- Fast food and takeaway: high cash volumes and young, rotating staff.
- Pubs, clubs and bars: shift takings from bars and bistros. We cover venue needs in more detail in our guide to safes for hospitality venues.
- Car parks, laundromats and vending operators: cash collected from machines.
If you only take a small amount of cash at one register, a till drawer safe under the counter may be enough. Many businesses use both.
Choosing the right deposit safe
Cash rating
Work out the most cash the safe will ever hold between collections, then ask your insurer what rating they require. Deposit safes in our range span a wide band. The Platinum Safes Defender series is listed at $10,001 to $20,000, the Platinum Safes Night Guard and Chubb Mini Banker Drawer Trap at $20,001 to $40,000, the CMI Commerce at $40,001 to $60,000, and the CMI CashGuard CG1 at $60,001 to $80,000. Our article on cash ratings vs fire ratings explains what the numbers mean.
Deposit opening size
Check that your standard banking bag or envelope fits the slot, drawer or hopper. If you deposit bundles of notes or coin bags, choose a larger opening or drawer.
Capacity
Deposited envelopes take more space than neatly stacked notes. Size the internal compartment for your busiest period between collections, not an average day.
Lock type
Choose dual key or dual code if you want two-person control, a digital lock if you need to change codes regularly, and time delay if robbery risk is a concern.
Placement
The deposit opening needs to be close enough that staff use it after every few sales, but out of customers’ view. Behind or under the counter is typical.
What deposit safes cost
In our range of deposit and drop safes, basic deposit containers and counter units start from a few hundred dollars. Rated drop safes such as the Platinum Safes Defender D1 start from around $860, the Platinum Safes Night Guard NG1 from around $2,240, and the CMI Commerce Safe Front Deposit COM1 from around $6,470. Prices change, so check the product page for current pricing.
Installation and anchoring
A deposit safe near a counter is an obvious target for carry-off, so it must be bolted down. Most have pre-drilled holes in the base for anchoring to a concrete slab. Our safe installers in Melbourne and nationally will check the floor, the delivery path and the best position for the deposit opening, then anchor the safe.
Once it is in, pair it with simple written procedures: when to drop, who holds keys or codes, and when to bank. Our guide to cash handling procedures for small businesses gives a practical template.
Frequently Asked Questions
What is a deposit safe?
A deposit safe, also called a drop safe, is a safe with a slot, chute, drawer or rotary hopper that lets staff put cash or envelopes inside without being able to open the main compartment. Only a manager or cash collection crew with the code or key can access the contents. It reduces the cash held in tills and limits who can touch the takings.
Can staff get money back out of a deposit safe?
Not through a properly designed deposit mechanism. Quality deposit safes use anti-fish baffles, rotary hoppers or trap drawers so items cannot be pulled back out through the opening. Staff without the main lock code or key have no access to the contents. Cheap slot boxes with simple openings offer much less protection, so check the deposit design before you buy.
What cash rating should a deposit safe have?
Base it on the most cash that will sit in the safe between collections, including your busiest periods, then confirm the requirement with your insurer. In our range, deposit safes run from basic units with low ratings through to safes rated $40,001 to $60,000 and above. Bolting the safe down is normally a condition of its rating.
Do deposit safes need to be bolted down?
Yes. A deposit safe usually sits near the counter, which makes it an easier target to carry off than a safe in a back office. Bolting it to a concrete floor through the pre-drilled base holes is the standard approach and is generally expected by insurers. Our installers can position and anchor it so the deposit opening stays convenient for staff.
