Deposits and other security amounts are easy to forget because they often sit unchanged for a long time. For UK small businesses, the key is to separate them from normal operating costs and review them regularly.

What should be in place?

  • the reason the money is tied up is clear
  • the contract or counterpart can be found quickly
  • payment and return are tracked separately
  • the balance is reviewed at each close

Where do mistakes happen?

AreaTypical problem
Classificationthe deposit is treated like a normal expense
Follow-upno one checks whether the amount is still active
Exitthe refund or offset is not processed cleanly

A practical routine

  1. Keep deposits separate from routine supplier activity and review them alongside Supplier statement reconciliation .
  2. Use the same thinking as Supplier prepayments and Customer prepayments , where timing differs from the cash movement.
  3. Review the balances within Balance sheet review before month-end , so they are not forgotten on the balance sheet.
  4. Keep agreements and support with Archiving accounting records , so the background remains clear.

In summary

Deposits stay manageable when they have a clear purpose, a clear account and a regular review at each close.
