Accelerating Cash Collections - Float Types and Techniques

## Managing Cash Collections and Disbursements

Two main objectives:

1. Collect receivables as quickly as possible

2. Delay payments legally within the permissible period

This improves liquidity and allows better control over working capital.

## Understanding Float

Float = the time delay between a sale and actual receipt of usable cash.

Type of FloatWhat Causes the Delay
Billing FloatTime between making a sale and sending the invoice
Mail FloatTime the cheque takes to reach the company by post
Cheque Processing FloatTime to process and deposit the cheque internally
Banking Processing FloatTime taken by the bank to credit the amount

> Mnemonic: B-M-C-B → Billing, Mail, Cheque Processing, Banking Processing

## Techniques to Reduce Float and Accelerate Collections

### 1. Concentration Banking

A decentralized collection method with multiple regional collection centers.

How it works:

  • Customers in each region send payments to their local collection center
  • Each center deposits into a local bank
  • Local bank transfers funds to the company's centralized (head office) account

Benefits:

  • Reduces mail and processing float
  • Local deposits are faster and more efficient
  • Funds quickly consolidated at head office

---

### 2. Lock Box System

A bank-operated system where customers mail payments directly to a Post Office Box (lock box) controlled by the company's bank.

How it works:

  • Bank collects cheques from the lock box multiple times a day
  • Immediately processes and deposits them into the company's account
  • Bank sends deposit reports to the company

Advantages:

  • Eliminates mail float and cheque processing float
  • Speeds up funds availability
  • No internal cheque handling needed by the company

Disadvantages:

  • Costly — banks charge fees for the service
  • Suitable only when cheque volumes are high and average cheque value is large

### Decision Rule for Both Systems

> Implement the system only if:

>

> Marginal income from earlier access to funds > Additional cost of the system

>

> - Benefit > Cost → Implement

> - Cost > Benefit → Avoid

Worked example

### Example 1

Lock Box Decision:

A company receives cheques worth ₹1 crore/day on average. With a lock box system, it can receive funds 2 days earlier. The bank charges ₹5,000/month for the lock box service. The company's opportunity cost of funds is 12% p.a.

Benefit (earlier access):

  • 2 days × ₹1 crore = ₹2 crore released earlier
  • Annual benefit = ₹2 crore × 12% = ₹2,40,000/year = ₹20,000/month

Cost:

  • ₹5,000/month

Decision: ₹20,000 > ₹5,000 → Implement the lock box system.

Net monthly benefit = ₹15,000.

⚠️ Common exam mistakes

  • Confusing Concentration Banking (decentralized collection using regional centers) with Lock Box (bank-operated PO Box system) — both reduce float but via different mechanisms
  • Forgetting that Lock Box has a disadvantage (cost) and is not always suitable — it requires high cheque volumes and large average cheque values to be worth it
  • Omitting the cost-benefit decision rule when asked about 'when to use' these systems — this rule is frequently tested
