Adult Volunteer Information This page contains information useful for our adult volunteers… OSM Training Videos Claiming Expenses * Additional point: If you do need paying urgently, finalise your “invoice” but then obviously let the treasurer know it’s there…! Event Costs on OSM When planning an event, there is a charge to take online payments through OSM. To allow for this, a small additional charge should be included e.g. if the supplier of an event charges us £13 per person, then the cost should be advertised as £13.75 (i.e. £13 + additional 75p) GoCardless charges = 1% + 20p OSM charges = 1.95% Event CostAdditional Charge£0 – £1050p£10 – £1575p£15 – £25£1£25 – £50£1.50
