Delivery & scaling
Demand can double in a fortnight with no extra kitchen. What breaks is sequencing, not cooking - and the fix is throttling, menu triage and a pack station, in that order.
The good problem
A platform feature, a viral clip, a rival closing, a wet Friday: delivery demand can double in a fortnight - or an evening - with no warning and no extra kitchen. What breaks first is never the cooking. It is the sequencing: tickets stacking faster than the pass clears, couriers queueing where prep should happen, and food dying in the window while the app promises times the kitchen stopped owning an hour ago.
Doubled volume mishandled is worse than volume declined, because every late, cold or wrong order arrives with a rating attached and the algorithm reads the ratings. The sequence below is the one that keeps quality and the listing intact while you find out whether the surge is a spike or a new baseline.
The sequence
The load nobody watches
The invisible casualty of a delivery surge is the extraction system. Doubled fryer hours mean grease loading the duct at roughly double the rate the cleaning schedule assumed, while the hotter, busier kitchen needs the airflow more than ever. A site that moved from moderate to heavy use has moved cleaning bands - from six-monthly to quarterly - whether or not anyone rebooked the contractor. Check the interval against the new hours in the same week you review the sales data; the fan that carried the boom should not be the thing that ends it.
Questions
Yes - briefly and early beats late and often. A short pause or busy-mode window while the line clears protects your delivery times and ratings, which are what the ranking algorithm actually reads. Extending quoted prep times is the gentler first lever; the mistake is holding a 25-minute promise you stopped being able to keep an hour ago, because every late order converts a customer into a bad review.
Cut, then bundle. Remove poor travellers and anything with a long, unshared prep chain; keep items that fire fast from common mise en place and survive twenty minutes in a box. Bundles and meal deals raise average order value, which matters because packaging, labelling and dispatch effort are per-order costs - fewer, larger tickets beat many small ones at the same revenue.
Hold the same lines you would in a full restaurant: hot food waits in hot-holding at 63C or above until dispatch, not in a bag pile; chilled items stay refrigerated until packing; times and temperatures stay logged even on the worst night. Volume pressure invites part-cooking buffers and cooling shortcuts - exactly the practices that turn one busy month into an incident investigation.
When the extra hours persist. TR19 Grease banding follows cooking hours: a kitchen that moves from a few service hours to 12-plus a day has moved from a six or twelve-month interval toward quarterly. If doubled delivery volume has your fryers running most of the day, reassess the interval now - grease loading tracks the hours, not the calendar, and the system was quoted on the old ones.
