Managing director Ian Carrotte said print companies would be left to count the cost if they put off pursuing late payments any longer than is needed.
His comments come as the agency helped to recover £900,000 in bad debt throughout August. Elsewhere, he said £600,000 had been written off that month – up from £410,000 in July.
"Still we keep on hearing that a printer is reluctant to ‘upset his customer’ by chasing his money when it is due. Tragically, this reluctance usually ends in the printer being more than just a little upset," he added.
"If money is due, chase it. If done properly you can actually enhance relations with your customer, not weaken it."
