For Shopify stores selling blinds, shades and window coverings
Your Options App Adds the Motor. It Can’t Read Your Width by Drop Table.
One roller shade. Twenty-four widths, thirteen drops, seven fabric bands.
That’s 2,184 prices sitting in a table your app has nowhere to put.
So the page ends up saying “contact us for a quote”, and the sale goes to whoever showed a number. Appify reads the price straight out of your supplier’s table. Width, drop, fabric band, lift, cassette. It even names the cell it landed in.

Why the search took this long
The First Five Minutes of Listing One Blind
Blinds break a normal options app in four specific places, and they’re all in the first five minutes of trying to list one.
A grid, not a formula
A real roller table steps from $366 to $553 between the 97 and 108 inch columns. That’s 51% more money for 11 more inches, because that’s where the fabric has to be seamed. An area formula smooths straight over it and quietly hands you the difference. As one merchant put it on the Shopify forum, “there is alway breakage between sizes.”
Fractions of an inch
Windows come in at 43 and an eighth, not 43. Another merchant’s summary of trying it natively: Shopify “does not have native support for made-to-measure products with flexible pricing. And it can’t do fractions.” Round to the nearest inch across a house and every blind is short.
Minimums that live on the wrong field
Chain drive goes down to 16 inches. Motorised wand needs 23. Quiet Lift needs 29 and a half. The minimum width isn’t a property of the blind, it’s a property of the lift they picked three fields later. Almost no options app can hold a rule that points backwards like that.
Deductions that change per product
Inside mount takes a quarter inch off a cellular shade. A sheerview cordless takes an eighth off the headrail and one and an eighth off the fabric. A skylight takes nothing at all, because finished size must be supplied. One deduction rule across a catalogue guarantees scrap.
What the reports don’t show
The Orders You Never Knew You Lost
None of these turn up in a report. The customer never complains, they just don’t come back.
The visitor who met a quote form at 11pm
They measured the recess, found your page, and got a contact form instead of a price. The next shop showed a number in four seconds. You never knew they were there.
→ A price from your own table, on the page, at any hourThe blind that was cut before anyone noticed
The order came through with a reverse roll and a cassette, which cannot be built together. By the time the factory flagged it the fabric was cut, and a cut order carries a 50% minimum charge.
→ Rules that stop impossible combinations before checkoutThe eighth of an inch they rounded off
The form only took whole numbers, so 43 and an eighth became 43. Every blind in the house is an eighth short, and every one of them is a remake at your cost.
→ Ordering in eighths, the way the factory takes itThe double deduction nobody caught
They took a quarter inch off before entering it, and the factory took another quarter off after. The light gap looks like a defect, and the remake comes out of your margin.
→ The deduction happens once, in the calculator, where they can see itThe motor that needed 29 and a half inches
They picked Quiet Lift on a 26 inch window. Nothing stopped them. Two weeks into a four week lead time, the factory rejected it and the conversation started again.
→ Each lift carries its own minimum width, enforced on the pageThe second window ordered three weeks later
Same room, same fabric, different dye lot. The colour is visibly off, it isn’t a warranty claim, and the customer blames you.
→ Reorder brings back the original spec, so a whole room can be ordered at onceYou can’t fix what nothing reports.
What Lands on the Order
Not a recess measurement in a notes field. Everything the fabricator needs, in the format they ask for it.
Reorder and cart recovery
Buying It Again Shouldn’t Mean Building It Again
Blinds are a whole-house purchase bought one room at a time. The second order should be the easiest sale you have. It’s also the one most likely to go wrong. A different dye lot on the window next door isn’t a warranty claim. It’s a complaint, and it’s yours.
It All Comes Back With It
Would you rather just go and use it?
Our Shopify demo store runs a real blinds configurator. Enter a width in eighths, switch the lift, watch the rules bite. Nothing to install and no signup.

Real People Who Have Built These Setups
Ask a question during the trial and you’ll get an answer while you’re still sitting in front of the problem.
Four questions that rule out an app in two minutes
Ask these before you install the next one, Appify included. They’re the four things a listing almost never tells you.
- Can it price from a width by drop table? Not a list of sizes you set up in advance. The actual grid your supplier sends you.
- Can one option limit another? The lift they pick should set the minimum width. Chain goes to 16 inches, Quiet Lift needs 29 and a half.
- Can a customer type 43 and an eighth? Or does the field round it to 43 and leave every blind in the house short?
- Does the deduction happen before the factory sees it? Applied once, in the calculator, where the customer can see what changed and why.
Four yeses is rare. Run them on the calculator at the top of this page before you run them on us.
You Might Be Wondering
“This sounds technical. I don't write formulas.”
Most merchants here don’t. A price grid is a table you paste in, not a formula you write. For the rest, describe how your supplier prices a blind in plain language and the AI-assisted setup builds it. Support will do the awkward part with you during the trial.
“My supplier's table has thousands of cells.”
That’s the normal case and it’s why this exists. A table with hundreds of cells per fabric band is data, not variants, so it never touches Shopify’s variant or option limits.
“Every product has different deductions.”
Expected. The deduction is a property of the product and the mount, so cellular, sheerview and skylight can each carry their own rule inside one store.
“I already have an options app.”
Most do, and for options they work. The question is whether yours can read a two-dimensional table, take a measurement in eighths, and refuse a size the factory can’t build. If any of that is happening by email, that’s the part this replaces.
“Will this slow my product pages down?”
No. Options load with the page and add to cart natively, without a separate cart flow or a third-party checkout.
“How do I know it fits my products before installing?”
Go and use it. Our Shopify demo store runs a real blinds configurator, so you can enter a width in eighths and watch the rules bite before you install anything.

Every Window Priced From Your Supplier’s Own Table
Not the standard roller. The one with the motor and the minimum width.
The one where the fabric caps out before the grid does.
The one that cost you a remake in March.
If it can’t handle that one, you’ll know inside a week and you won’t have paid anything.

Frequently Asked Questions
Can it price from a width by drop table?
Yes. A two-dimensional price grid is a lookup, so the price comes from the cell your supplier set rather than from a formula that smooths across the bands.
What about the jump between size bands?
That’s exactly why a table is used instead of a rate. A real roller grid steps from $366 to $553 between the 97 and 108 inch columns, and a lookup reproduces that step precisely.
Can customers order in fractions of an inch?
Yes. Widths and drops can be entered in eighths, the way a factory takes them, rather than rounded to whole inches.
Can the minimum width depend on the lift chosen?
Yes. A rule can read one option to constrain another, so chain drive, cordless, motorised wand and Quiet Lift can each carry their own minimum width.
Can I stop combinations that can't be manufactured?
Yes. Options can be made mutually exclusive, so a reverse roll and a cassette can’t be ordered together, and a blocked size refuses to price with a line explaining why.
Do mount deductions happen automatically?
Yes. Inside mount can deduct while outside mount does not, and specialty products that need a finished size can take no deduction at all.
How many price cells can one product hold?
Enough for a full supplier table. Prices live in a pricing table rather than in Shopify variants, so a product with thousands of size and band combinations never runs into the variant or option limits.
Can I add motors, remotes and cassettes?
Yes. Add-ons can be priced per unit, per foot or per metre, and conditional rules can show remotes and hubs only when a motor is selected.
Does this create extra variants in my store?
No. Options and pricing live outside the variant system, so no size or fabric combination becomes another SKU.
Do I need to know how to write formulas?
No. A grid is pasted in as a table. For everything else, describe your pricing in plain language and the AI-assisted setup writes it.
Can I edit without customers seeing a broken page?
Yes. Work in draft and publish when you’re ready. Every publish saves a version and you can restore an older one at any time.
What does it cost?
From $39 per month, with a 14-day free trial. The subscription scales with how much you use the calculators, and monthly AI credits are included, with an overage charge only if you go past them. Shopify Partner development stores are free.
