Late Payment Law For Cashflow For Business
Many companies do not realise that there is late payment law; The Late Payment of Commercial Debts (Interest) Act 1998 (the Act) and there are many companies who decide they are going to pay late to improve their cashflow position and seem to think they can merely pay what is on the invoice when they decide to pay (we know the head of finance of one multinational who boasted they earned over £2m per year by deliberately paying invoices on 90-120 days instead of the agreed 60 days eom).
Late payments create cash flow problems and can increase the risk that you will not be paid at all. Using your legal right to claim interest from late-paying customers can encourage customers to pay on time.
The statutory right to interest and compensation applies to all contracts. You need to decide whether to enforce your rights, and if so how.
2. The right to charge interest
Every business has a statutory right to charge interest on late payments
c. The right applies to sales to business and public sector customers.
d. The right does not apply to sales to consumers.
3. You can set out in your own contractual agreement instead
a. The contractual agreement must provide a 'substantial remedy' if the customer pays late.
b. The customer cannot impose unfair terms: for example, contractual payment periods are usually capped at 60 days.
c. Public sector customers must pay within 30 days and interest on late payments cannot be lower than the statutory amount.
d. In the absence of any specific payment terms, the statutory right will apply
e. Interest starts being chargeable from the end of the agreed credit period
f. If you have not agreed credit terms, normally a payment is late after 30 days.
4. What difference does it make?
a. Under the law, company finance directors who made a habit of taking extra credit from suppliers to improve cash flow may have had to think again.
b. There will be less free credit to be had just by paying slowly
The 'base rate +8% set out in the law means money 'borrowed' by delaying payment is more expensive than overdraft money from the bank.
5. The rate of interest
The law gives you the right to charge interest at the Bank of England base rate plus 8%
a. For example, todays base rate is 3.75% so interest can be charged at 11.75%
b. You can also claim Statutory Charges and reasonable debt recovery costs
c. You can claim £40 for debts of less than £1,000, £70 for debts between £1,000 and £10,000 and £100 for debts of £10,000 or more. #
d. If your costs are higher than this (for example, if you are using a debt collection agency) you can claim 'reasonable' recovery costs.
e. You can only claim these costs if you are claiming the interest due under the Act. If you do not claim interest, or you claim it under a contractual provision or the provisions of a different Act, you cannot claim the costs.
6. At all times assess the effectiveness of your credit control system and always be clear in your terms and condition about who is paying you and when and never be frightened to ask for your monies son time plus interest as you retain the right to define your own terms and conditions.
7. Inform customers when interest begins to accumulate
8. Claims for interest on late payment do not have to be made straight away.
a. A supplier has six years in which to make a claim
b. Trading terms must have been agreed and the customer duly notified when interest began to accumulate.
c. The six-year claims period is the same throughout England, Wales and Northern Ireland, but the period is only five years in Scotland.
d. Businesses may still make claims after they have stopped supplying a customer
e. Liquidators and receivers acting in connection with a business can also pursue ex-customers for interest on late payments, going back up to six years.7. What if a customer objects?
9. Despite the law, your customer may be unwilling to pay interest on late payment - but they cannot 'opt out' of doing so. In the interests of customer relations, try other ways of obtaining your money before considering legal action.
