A permanent placement fee is a large lump sum, and a client under pressure will let it drift or lean on the rebate period to justify a pause. On a temp or contract desk the pain is different: you have already funded the contractor's pay, and every week the client is late is a week you are out of pocket. A graduated, professional escalation applies real pressure while keeping the tone of a business chasing a business.
RobinReturn is general England & Wales county-court recovery for an undisputed debt up to £10,000. It does not resolve a rebate dispute, a back-door hire, or an argument over whether the fee is even due — if your case turns on those, take advice. For a clear, overdue invoice the workflow does the paperwork and you stay in control.
Many overdue fees settle at the reminder or Letter Before Action stage, once it is clear a County Court claim is the next step — though every case is different and nothing is guaranteed. Statutory interest (Bank of England base rate plus 8%) and fixed compensation are recoverable from the debtor, and they are yours to keep.
