What it means
When your business receives payment by cheque, waiting for the post to arrive, processing the paperwork, and walking to the bank branch delays access to your money. A lockbox service solves this bottleneck.
You instruct your customers to mail their payments to a dedicated PO Box controlled entirely by your bank. Bank staff collect the mail multiple times a day, open the envelopes, deposit the cheques into your business account straight away, and securely send you the payment details.
This process dramatically shortens the collection period, often by several days, giving you faster access to your working capital. For managers, this is crucial because cash flow is the lifeblood of any organisation.
Faster collections mean your cash is available sooner to pay suppliers, fund payroll, or invest in growth. It also strengthens internal financial controls.
Since your own employees never touch the physical cheques, the risk of internal theft or human error drops significantly. While traditional cheque usage is declining, lockbox services have evolved.
Modern providers digitise incoming payments and integrate the data directly with your accounting software. This automation matches customer payments to outstanding invoices automatically, saving your finance team countless hours of manual data entry.
Imagine having a secure drop-box outside your house where tenants slide their rent cheques directly to your landlord, rather than waiting for you to collect them, drive to the bank, and queue at the counter.
In practice
Real-world examples
Example 1
A boutique furniture maker receives about fifty cheque payments a month from retail stockists, averaging $240 each, or roughly $12,000 a month. With a bank lockbox, cheques are processed the day they arrive instead of waiting for a weekly trip to the branch. The cash lands nearly four days sooner, which helps the business pay its timber supplier on time.
Example 2
A regional commercial cleaning contractor manages eighty corporate clients who pay by post. Setting up a lockbox cuts administrative data entry time by ten hours a week. It also removes the risk of cheques sitting unbanked in a drawer during staff holidays.
Example 3
A wholesale food distributor supplies cafes across the country and receives about $60,000 a day in customer remittances. Using regional lockbox addresses reduces postal transit times, so funds reach the account up to three days earlier. The finance team uses the daily bank file to see which invoices have been paid before the credit controller makes her morning calls.

Formula
Calculation
Cash Released = Average Daily Collections x Reduction in Days of Collection Time
Worked example: a business collects $50,000 a day by cheque and the lockbox cuts mailing, handling and deposit time by 2 days. Cash Released = $50,000 x 2 = $100,000, which is available a little earlier and stays available for as long as the lockbox is in use.
To judge whether the service is worth paying for, value that cash at the interest earned or borrowing saved. At an annual rate of 5%, Annual Benefit = $100,000 x 5% = $5,000. If the bank charges $400 a month, the annual fee is $400 x 12 = $4,800, so the interest benefit alone barely covers the cost and the case rests on the staff time and control benefits as well.Case study
Seen in the real world
This is a fictional, illustrative scenario. Brighton Office Supplies, a mid-sized distributor of stationery, struggled with delayed payments because cheques were mailed to its head office and often sat on desks for days before being processed. To fix this, the finance manager set up a bank lockbox service in London. Previously it took an average of six days from the customer writing the cheque to the funds clearing in the company bank account.
With the lockbox, bank staff collected the mail twice daily and deposited cheques within hours. The collection cycle dropped to just two days. With annual revenue of $3,000,000, which is about $8,200 a day, reducing the float by four days released roughly $33,000 of trapped cash. The service was not free.
The bank charged a $300 monthly fee plus $0.50 per cheque, and with about 400 cheques a month the annual cost was 12 x ($300 + $200) = $6,000. Interest on the released cash at 5% was only about $1,650 a year, so the real saving came from the accounts receivable team, whose time spent opening envelopes and stamping deposit slips fell by half. The finance manager concluded the lockbox paid for itself mainly through staff time and tighter control, not through interest.
Watch out
Common mistakes
- Assuming lockboxes are only useful for large corporations, ignoring the benefits for growing small businesses.
- Failing to integrate the lockbox data feed with existing accounting software, creating extra manual reconciliation work.
- Forgetting to update customer billing addresses, causing payments to still arrive at the main office.
