Are you struggling to work out why sales fell off this week? Is it the algorithm, the weather, the new place down the street? Did something break that nobody told you about? Should you throw a promo at it?
When one owner's orders went from 59 to 21 in a single period, the first thing I checked was the campaigns. That's what a promo ending usually looks like, and it was the answer. Most drops I look at come down to something just as ordinary.
This post is the order I check things in, with where to look in each portal. Start at the top, because the cheap, common causes are the ones people skip.
Quick answers and quick fixes
- Down for one or two days? Wait. One or two bad days isn't something to solve for. Compare full weeks and full months.
- Did a promo end or change? Check end dates and schedules in each app's Marketing section before anything else.
- Edited the menu in your POS? Check your item-level BOGOs. A POS edit can change item IDs and quietly break them.
- Not sure people can find you? Search from a phone with an address inside your delivery zone, at lunch and at dinner.
- Ads getting fewer impressions? Nudge the budget, or replace a DoorDash listing that's been running more than 6 weeks.
- Rating slipping? Look for a run of low reviews, or one customer leaving several.
Is the drop real, or just a slow stretch?
First make sure you're comparing like with like. A full week against the same week before, or a full month against the last full month. Mondays are slow everywhere, and the peak runs 6 to 10 PM, so a Monday next to a Friday tells you nothing. Skip the dashboards' "vs 7 days prior" view. I've seen it show sales up 11,000%. I explain why in how to read your delivery statements.
Then split it two ways:
- Which apps? If DoorDash and Uber Eats both dropped in the same week, I look at things on your side first, like hours, the kitchen, weather and holidays. If only one app dropped, I look inside that app: its campaigns, its listing, its rating, its menu.
- Orders or ticket size? Sales are orders times average ticket. Fewer orders points to traffic or conversion. Same orders at a smaller ticket usually means a spend-and-save offer or a bundle stopped running.
Did anything change in your campaigns?
This is the most common cause I find, and the easiest to miss. Open the Marketing section on each app and check:
- End dates. A new-customer BOGO that ended last Sunday shows up as a drop this week.
- Schedules. I once looked into a "dud" offer that was only live 5 hours a day.
- Changes someone else made. Reps set up and edit campaigns, and Uber sometimes changes offers itself during national promos. On Uber, a live campaign can't be edited, only ended and recreated, so check that nothing got ended along the way.
- Ad credits. If a credit ran out, your ad spend may have stopped with it.
Did a menu or POS change break something?
If you run Toast or another POS, editing an item there can change its item ID on DoorDash. Any item-level campaign tied to the old ID stops working, and nobody tells you. I learned this one the expensive way, when a BOGO campaign just went flat.
Other quiet breaks I see: items marked out of stock in DoorDash's menu manager come back after 24 hours, 86'd items that don't sync, photos you uploaded to DoorDash overwritten by the next Toast publish, and a publish that pushed every pending change live at once. I go through each one in fixing Toast menu sync problems.
The check: open your store on a phone and look at it like a customer. Is the BOGO tag on the items it should be? Are your top sellers available and photographed? If not, fix the item and rebuild the campaign.
Can people still find you?
Search for your store from a phone with an address inside your delivery zone, once at lunch and once at dinner. If you don't show up, or show up as closed, check:
- Hours and pauses. On DoorDash, Store availability shows your hours, special hours and closures, with a View history option. Insights, then Operations quality, shows downtime during business hours (DoorDash learning center). Pausing in a rush is fine. Just remember to turn it back on.
- Closed days. Delivery demand is occasion-based. If someone wants dinner on a Tuesday and you're closed, that order goes to whoever is open. A store that's dark several days a month also gets less favorable placement on the days it's open, so you pay for closures twice.
- Category tags, and for virtual brands, DoorDash's rule that a new brand's menu be at least 50% different from your others.
Is it a traffic problem or a conversion problem?
If none of the above explains it, split the funnel. On Uber Eats, go to Analytics, then Customers, then Conversion Funnel. It shows how often your menu was viewed, how often items went into a cart, and how often an order was placed (Uber Eats academy).
- Views down: traffic. Look at your sponsored listing. A listing left at the same level for a long time goes stale, and manual bids in a crowded market can lose impressions. More in how to set your ad bids and budgets.
- Views steady, orders down: conversion. Check the rating, a run of low reviews, a missing photo or a sold-out best seller.
I cover the two buckets in more depth in why your restaurant is invisible on DoorDash and Uber Eats.
Is it something outside your store?
Sometimes it is. Bad weather usually lowers delivery sales. People expect the opposite, and it's usually not the case. Holidays move demand around. Seasons matter too: for a coffee bar we manage in Philadelphia, January was the low month.
A new competitor is the one owners worry about most. Don't react on price. A smash-burger ghost kitchen we manage in Houston had its best day ever the day a hyped competitor opened nearby, from the overflow. If you want to see where you actually stand, here's how I size up local competitors.
And sometimes the dip is the plan. When a store moves from growth to profit, we pull back on giveaways, so sales come down while the payout ratio goes up. At an Arab coffee bar in New Jersey, the payout ratio went from 48.6% in May to 53.0% in June 2026 when we made that pivot. Lower sales, more money kept per dollar.
What I wouldn't do is throw a new promo at a dip before you know the cause. If the real problem is a broken BOGO or a store that was paused for two evenings, a new offer just adds cost on top of it. Find the cause, fix that one thing, and give it a full week before you judge it.
Example: the checklist in one picture
Work through it in order and stop when you find something. Then change one thing and give it a full week or two.

Resist the urge to fix everything at once. If you change the menu, the prices and the promos in the same week and sales come back, you won't know which change did it.
How does Blender handle a sales drop?
We watch spend, redemptions, ad returns, store views and new customers every week, so most drops show up in days. The monthly report decides what changes. When something does need fixing, we change one variable, write down why, and read it on a full month. That's how we run campaign management, and the thinking behind which lever to pull is our campaign strategy work.
We also say so when a month misses. At that San Francisco diner, September 2026 came in at $34,521 across Uber Eats, DoorDash and Grubhub, against a $36,000 goal, a 4.1% miss. The payout ratio was 76.1%, above the 70% target. Under the main brand's drop, three of the smaller brands grew: breakfast up 73.5%, steaks up 49.1% and pies up 43.6%. The report named Uber Eats store views as the first thing to fix, and the stale DoorDash listing is being reposted.

FAQ
Why did my DoorDash sales suddenly drop?
The most common causes I find are a campaign that ended or changed, a POS menu edit that broke an item-level promo, store hours or pauses, a stale sponsored listing, or a run of low reviews. Check those before blaming the algorithm.
Why did my Uber Eats orders go down?
Open Analytics, then Customers, then Conversion Funnel. If menu views fell, it's traffic, so look at your ads and offers. If views held and orders fell, it's conversion: rating, photos, price or a sold-out best seller.
Can editing my Toast menu hurt my DoorDash sales?
Yes. Editing an item can change its ID on DoorDash and quietly break item-level campaigns like a BOGO. Make changes on a Monday and rebuild those campaigns right after you publish.
How long should I wait before reacting to a sales drop?
One or two bad days isn't something to solve for. Compare a full week with the week before, and judge changes on full months.
Does bad weather increase delivery orders?
Usually not. In the stores I manage, bad weather tends to lower delivery sales, even though most people expect the opposite.
