Methods and systems for replenishing a consumable include order satisfaction responsive to an indication of imminent failure or depletion of a consumable based on detected parameters. A sensor reading may indicate that a consumable is performing below a threshold, or has limited remaining capacity. Responsive to a determination that a replacement is necessary, the method may recommend one or more alternatives. The recommendation may be made based on how closely a candidate replacement's performance or other characteristic (e.g. cost, capacity) matches that of a currently-used consumable. The recommendation may be based on one or more attributes of a candidate replacement compared to a currently-used consumable. An order may be automatically placed according to the currently-used consumable or the recommended alternative(s). The order may be delivered with instructions regarding where and when to replace the consumable.
