Hi ELSLtd, thanks for joining the QB Community - supplier credits are only available through our higher tiered plans; the lowest plan to access this is QB Online Essentials, which is priced at £24 p/m + VAT. Alternately, you can enter a credit on the supplier account manually using a journal entry - we'd recommend reaching out to your bookkeeper or accountant if you're unsure on how to enter this. :)
