The first rule of business is to never to give anybody credit facilities unless they have agreed to your terms and conditions of trading in writing and you have carried out a credit reference check.
If you are prepared to carry out work without doing the above, expect to be shafted on a regular basis. This world is full of rogues and crooks.
If your customer is not prepared to pay up front or to undergo credit reference checks and also agree to your terms and conditions of trading then don't work for them. You might as well sit at home and earn nothing, than to work hard and still earn nothing!
You can carry out a simple credit reference check yourself on a Company's financial stability by using information stored at Companies House for a very reasonable fee:
www.companieshouse.gov.ukWhen your customer agress to your terms ask him for a written purchase order for your services on the terms, and if possible, the price agreed.
In the unlikely event you still don't get paid within the terms of your terms and conditions take legal action through the courts under the Late payment of Commercial Debts (interest) Act 1998. You can even do this on-line.
www.courtservice.gov.ukWhen taking court action you are entitled to claim interest at 8% over base, a late payment compensation fee and repayment of court fees.
By the way, the late Payment of Commercial Debts (interest) Act 1998 also states that unless your terms and conditions ask for anything different then the recognised legal period for payment is 30 days from submission of invoice.
More information regarding how to get paid on time can be found at
www.payontime.co.ukI have only ever not received payment when the debtor has gone into liquidation. This was mainly during the last recession. No customer of mine went into liquidation between 1998-2007. I have had one this year but I expect some more in the future - a new recession is on the way! Protect yourself now by having a robust 'debt recovery' system. The good times are over!
