Your BFCM Plan Shouldn't Start With a Discount Percentage

Somewhere in your BFCM plan there is a blank space next to the words "discount %". That blank will eat more hours than anything else on the page. It is also the one decision on that page your competitors already made for you. By late November your category has settled into a range, and everybody is standing inside it. Pick 25, pick 30, you are moving around a room somebody else built. At 300 orders and an $85 average order value, that whole argument is worth $1,275 for the week. Nobody asks who is receiving the 25%. That question is worth twice as much.

Starting with the percentage feels like starting with the hard part. It goes on the banner. The ad creative gets built around it. It is the one number visibly attached to margin, so it feels like the risky one. It is still the wrong place to start. Depth is the last number on the page, not the first. Choose it first and every other decision gets bent to justify a number you picked blind.

By the end of this you will have the four decisions in a BFCM plan, listed in the order that protects margin. Plus one calculation you can run against your own order count before the next planning call. Start with why the percentage was never yours to pick.

The Percentage Is the One Number Your Competitors Already Chose for You

During BFCM week, a shopper is not comparing your offer against your own full price. They are comparing it against a screen of similar offers from stores selling similar things. That comparison squeezes every category into a narrow band by late November. Your store does not set the band. It joins it. So depth is the decision you control the least and the one that eats the most planning time. Bad trade. And easy to prove with your own numbers.

Why the Percentage Wins Every Planning Meeting

It wins because it is the only decision that fits in one cell. "Who is eligible for an offer" needs a paragraph. "What the offer attaches to" needs a diagram. "Does the deadline hold" needs somebody to open a second tab and check. A percentage needs one integer, and one integer is what a meeting can hold. So merchants keep confusing the decision that is easiest to argue about with the decision worth arguing about. The percentage is not the biggest lever in the building. It is just the easiest one to see.

What Five Points Actually Buys

Run it at your own volume. Take 300 orders in BFCM week at $85 each. The gap between 25% off and 30% off is $4.25 an order. Across the week, $1,275. Call that the five-point argument, because that is the whole prize for winning it. Now ask what the meeting skipped. Of those 300 orders, how many came from dedicated buyers, the ones already reading reviews and moving toward checkout? Use your own share. Say 40%. That is 120 buyers taking a 25% discount that changed nothing. $2,550 gone.

The decision What it is worth at 300 orders and $85 Planning time it gets
25% off versus 30% off, all week $4.25 per order. $1,275 total. Weeks. Plus the whole meeting.
120 orders that were converting anyway $2,550 paid for sales you already had. Usually zero minutes.
Cutting that 40% share down to 20% $1,275 back. Headline number untouched. Never on the agenda.

Look at the last row for a second. Cut the share of discounted orders that were converting anyway from 40% to 20%, and you get $1,275 back. That is exactly what winning the depth debate is worth. And you never touched the number on the banner. Your offer still looks just as generous to everyone who needed it.

The five-point argument is worth $1,275 at 300 orders. The question nobody raised is worth twice that. You have been spending your scarcest planning hours on the cheaper one.

Three Decisions Sit Underneath the Percentage, and Each One Changes What It Is Worth

A promotional plan is four decisions, not one. Who is eligible for an offer at all. What the offer attaches to. What the deadline is and whether it holds. Then, fourth, how deep the discount goes. The market has not pre-decided the first three, which is exactly why your margin lives there. Each of them also changes the answer to the fourth. Answer the fourth first and the other three get bent to fit it.

What the Offer Attaches To Beats How Deep It Goes

A 25% discount on whatever lands in the cart is one thing. A 25% discount on a cart you built to shape is another. Same $85 order. Say your structure moves that basket to $115 before the discount applies, through a spend tier or a bundle. Now 25% off $115 leaves you around $86 net. Above where you started at full price. The percentage never moved. The thing it multiplied did. Planning depth first means picking a multiplier before you know the balance.

A Deadline That Holds Is Worth Discount Points

Urgency gets filed under conversion tactics. It belongs in the margin column. If a shopper believes the offer genuinely ends, the clock does part of the persuading, and your number can be shallower for the same job. If they have learned your timer resets on refresh, or the code still works Tuesday, the clock does nothing. The discount carries the load alone. Stores with a deadline nobody believes pay for it in percentage points every year and never see the line item.

Percentage-first plan Structure-first plan
First decision made How deep the discount goes. Who is eligible to receive an offer.
What the number applies to Whatever happens to be in the cart. A basket the plan was built to shape.
Who receives it Everyone, dedicated buyers included. Visitors likely to leave without purchasing.
Role of the deadline Decorates the banner. Does part of the selling, so depth can be lower.
How the number gets chosen Argued in a meeting, benchmarked against last year. Calculated from the three decisions above, then tested.
If a competitor goes deeper You match, and the plan has no second move. Three other levers exist before price gets touched.
A flat sitewide percentage is not a strategy somebody chose. It is what is left on the page when the three decisions underneath it were never made.

The structural layer is the part most BFCM plans skip. Instead of one number applied to everything, Growth Suite runs a scheduled campaign with spend tiers. So 10% under $100, 15% from $100 to $150, 20% above that. Now the discount shapes the order instead of only shrinking it. Its discount rules then fence off the parts of the catalog that should never be in the promotion. Exclusions by vendor or product title, plus a hard dollar cap so no single order runs away with your margin.

Depth Is an Output of the Plan, Not an Input to It

"What percentage should we run" cannot be answered until you name who receives it. Not a hard question. An unanswerable one. Your store has two kinds of visitor in it, and the same number does opposite things to your profit on each. No single number is right for both.

The Same 25% Does Two Opposite Jobs

Send 25% to a shopper who read the reviews, compared two variants, and is halfway into checkout. That discount is a refund on a sale you already had. Send the same 25% to a window shopper drifting through the catalog. She is one distraction from closing the tab, thinking "I'll buy it later." Now the discount is the entire conversion. Same number. Opposite outcomes. Ask what percentage to run sitewide and you are asking your store for one answer to two populations that need different ones. Then you blame the answer when margin comes in soft. The number was never the failure. The question got asked before anyone named the audience.

Why the Range Collapses Once the Other Three Are Set

Fixing the first three decisions does something useful to the fourth. It shrinks it. If only visitors likely to leave without buying are eligible, your depth no longer has to defend itself against your whole customer base. If the structure lifts basket value first, you can go shallower and still land where you need to. If the deadline holds, the clock does part of the work. A fifteen-point argument turns into a four-point question. And four points is small enough to settle with data instead of volume.

Every point of credibility your deadline does not have is a point of discount you will pay to replace it.

Once depth belongs to the visitor instead of the store, you need something that holds more than one answer at a time. Growth Suite reads live session behavior and sets both depth and duration per visitor, inside the minimum and maximum you set. A high-interest shopper gets a smaller discount on a shorter clock. A drifting visitor gets more room. Each offer carries a unique single-use code, deleted from the Shopify backend the moment the timer hits zero. The deadline is enforceable rather than decorative, and the code cannot live forever on a coupon site.

Decide the Percentage Last, and Let a Test Decide It Instead of the Room

Here is the strange part. The five-point argument is the only decision in the whole BFCM plan that is cheap to test. It is also the one most often handed to whoever has the most authority in the room. You settle the testable item by vote, then give the untestable ones whatever is left of the hour.

The Order of Operations, Written Out

  1. Decide who is eligible: be specific enough that a dedicated buyer already at checkout is excluded by design, not by luck.
  2. Decide what the offer attaches to: a spend tier, a bundle, a threshold, a post-purchase add-on. Something that shapes the basket instead of only shrinking it.
  3. Decide the deadline, then verify it: refresh the page, open a new tab, come back tomorrow. A deadline that fails any of those is not a deadline.
  4. Only now, pick the depth: and pick it from a split test, not from last year's number or a category benchmark.

Three of those four are decisions your competitors are not making. That is the whole reason the margin sits there.

What to Do With the Meeting You Were Going to Have

Keep the meeting. Change the agenda. Spend it on eligibility and structure, because those two cannot be tested cheaply and they need human judgment. Then take the depth question out of the room. Route it to a split test on live traffic, judged on total revenue or margin, not conversion rate alone. A depth that wins on conversion and loses on profit is the classic false read of the season. Run it now, on ordinary traffic. Answer it during BFCM week and you are reading the most distorted week of the year. Every visitor is already being discounted by somebody else.

Are We Doing 25 or 30?

Depth is the number you control the least. The market squeezed your category into a band before you opened the plan, so the five-point argument is the least useful fight on the page. At 300 orders and $85, winning it outright is worth $1,275. Cutting the share of orders that were converting anyway from 40% to 20% is worth the same money. And it costs nothing on the banner. Three decisions set what any percentage is worth. Who is eligible, what the offer attaches to, whether the deadline holds. None of them have been decided for you.

Run one line this week. Take last November's order count, multiply by your average order value, then by five percentage points. That is what the depth debate is worth to you, in dollars, specifically. Then write down your honest estimate of how many of those orders came from buyers already heading to checkout. Bring both numbers to the next planning call and watch which one people want to talk about. When somebody asks whether you are doing 25 or 30, you now have the better answer ready. Wrong first question. Who is getting it?

If your BFCM plan keeps starting at the blank space next to "discount %", Growth Suite helps you tell walk-away customers apart from dedicated buyers. It holds the offer back from the ones already moving toward checkout. So the depth you land on gets spent on orders that would not have happened, without discounting the shoppers who were already going to buy. It is free to install on the Shopify App Store, with a 14-day free trial.

Frequently Asked Questions

How much should I discount for Black Friday?

Decide it last, not first. Depth only becomes answerable once you have fixed three things. Who is eligible for an offer, what the offer attaches to, and whether the deadline actually holds. Each of those changes what a given percentage is worth to you. Your category compresses into a narrow band during BFCM week anyway, so the profitable question is not how deep to go. It is who receives it and what it multiplies.

Do I have to match my competitors' Black Friday discount?

You need to stay inside the band your category settled into. Matching point for point buys almost nothing. During BFCM week your shopper is comparing you against a screen of similar offers, so three points either way rarely decides anything. Three things do decide it. Whether the offer applies to a basket you shaped. Whether your deadline is believable. And whether that shopper needed a discount at all. Match the band, not the number.

What should a BFCM plan include besides a discount percentage?

Three decisions that come before it. Eligibility, meaning which visitors can get an offer and which ones convert at full price without one. Structure, meaning what the offer attaches to, like a spend tier, a bundle, or an add-on that raises basket value before the discount applies. And the deadline, including checking that it survives a refresh, a new tab, and a return visit tomorrow. Depth is the fourth item on that list.

Is a deeper Black Friday discount always more effective?

No, and the reason is who gets the extra depth. Going from 25% to 30% adds cost to every order in the week. That includes orders from dedicated buyers who were already at checkout and needed nothing. If a real share of your holiday orders would have happened anyway, the deeper number mostly raises what you pay for sales you already had. Depth without eligibility control is just an across-the-board cost increase.

When should I lock in my Black Friday discount depth?

After the other three decisions are made, and after a split test has narrowed the range. In practice that means locking it well before the traffic shows up, not in the final week. Answer the depth question during BFCM week and you answer it on the most distorted traffic of the year. Every visitor is already being discounted by somebody. Test it on ordinary traffic weeks earlier, then commit and stop reopening it.
