‘I was initially introduced to 6 4 G Ltd by my invoice financier as I needed someone to undertake the credit control for my business and improve the cash flow. They very quickly evidenced their understanding of what we do and became a seamless part of our business. Within a few weeks we had also outsourced our payroll and complete bookkeeping requirements to them. As far as our customers are concerned, 6 4 G is part of Crucial Environmental; handling all our credit control, payment, invoicing and purchase ledger queries through the dedicated phone line and email address.
As my team spend the majority of their time out on site, it is essential for us to have the confidence that our back office requirements are being handled professionally; this is what we get with 6 4 G’

‘While we transitioned our accounting function we quickly realised we had issues regarding the allocation of previous payments coupled with ongoing credit control across ‘000’s of transactions. We outsourced this area of grave concern to Harley and Wendy of 64G Ltd. Within a short time frame and through seer hard work on their behalf our Aged Debtors was pulled into shape and our credit control brought up to speed within a timescale we couldn’t have anticipated. Their commitment, hard work, diligence and ability to un-pick incorrect allocation issues coupled with credit control has brought our business from what can only be considered a very dangerous situation. We are and will always be thankful to 64G for what they have achieved on behalf of our business. I couldn’t recommend 64G enough and would welcome anyone who is considering their services for a more detailed reference’

‘We initially approached 6 4 G to investigate and correct some historic misallocations on our ledger; We were so impressed with the accuracy and commitment that we requested 6 4 G to take over all the credit control for our sales ledger. At the time our bank was increasing pressure to bring in significant cash receipts as, due to the previous misallocations, we had significant ageing and growing debts outstanding. By the end of month 1; despite being given the cash target only a week before month end, 6 4 G had collected sufficient cash to please the bank. By the end of month two, 6 4 G had smashed the cash collections target by 140%. With 6 4 G our ledger is clear and our end column if completely in control. Most importantly the processes and procedures implemented mean, our cash comes in smoothly and on time month on month.’
