A company that processed and handled the ordering of several large charities' fundraising materials has gone into voluntary liquidation.
The closure of Netpack Fulfilment was announced last week by its parent company, Otter House, a publisher and distributor of calendars, cards and gifts, after what was described in a statement as "increasing competition in the fulfilment sector".
The three charities said alternative arrangements were being made.
Stephen Hobson, an insolvency practitioner and partner at the accountancy firm Francis Clarke, who is assisting Netpack in its liquidation process, said: "Despite ongoing investment in the business, the financial outlook for the company has deteriorated in recent months, with the board of directors finally concluding that the company was unlikely to achieve profitability going forward."
Anthony Jervoise, a director of Netpack, said all stock previously stored in its warehouse would be returned to the relevant charities or forwarded to alternative fulfilment companies by 20 May.
A branch manager for the RSPCA, who asked not to be named, said he was concerned that he would be short of fundraising materials because all of the branch's branded items, such as pens and pencils, came from Netpack.
He said the branch had planned six events in June, for which he would need materials, and that he had only enough stock for one at present.
An RSPCA spokesman said: "There has been a temporary interruption to supplying our branches with fundraising goods while we make alternative arrangements. But this is now in hand."
Claire Robinson, fundraising manager at the Dogs Trust, said the situation was under control and that Otter House would find another fulfilment company to carry out these services. "For us, it should be business as usual," she said.
