Resolving A Long-Running Billing Dispute With A Commercial Supplier

This example describes a typical challenge Pioneer Estates addresses for commercial property clients. Specific client details, site names and financial figures are not disclosed.
What the client needed to resolve
A managing agent acting on behalf of a commercial landlord became aware that a supplier was consistently invoicing at a unit rate higher than the agreed contract. The discrepancy had continued for several billing periods and, despite internal attempts to resolve the matter directly with the supplier, no correction had been made and no formal acknowledgement of the error had been received.
The managing agent's team had made multiple attempts through the supplier's customer service process, but without detailed documentation of the contracted rate, the invoiced rate and the specific periods affected, the supplier was not progressing a resolution. The dispute was consuming management time without moving towards a conclusion.
The landlord faced the prospect of having overpaid for a significant period, with no clear pathway to recovering the difference or preventing the same billing error from continuing on future invoices.
Pioneer's approach, step by step
Pioneer obtained the contracted supply agreement and reviewed it alongside the invoices issued during the disputed period, identifying the exact rate discrepancy, the affected billing periods and a calculation of the amount overbilled.
Pioneer documented the dispute formally, setting out the contracted rate, the invoiced rate, the discrepancy per invoice and the cumulative total — providing the supplier with a clear, structured case that could be escalated within their organisation.
Pioneer managed all ongoing correspondence with the supplier on behalf of the client, following up consistently and escalating within the supplier's dispute resolution hierarchy until a written acknowledgement was received.
Once the supplier acknowledged the error, Pioneer verified that the corrected billing rate was applied to subsequent invoices and confirmed that any agreed credit note covered the full overbilled amount.
