Plan the next drop with a clothing inventory app
that counts every size and colorway.

Tell the agent how your styles, sizes and seasons work. Netiva builds a web app that tracks stock for each variant, lines up every drop and shows which sizes sold out first.

Starter prompt

Build a clothing inventory web app for a small fashion label that sells in its own shop and through a Netiva store. Track styles with a style number, season, category, size scale, unit cost and retail price. Give each style a variant for every size and colorway with a SKU, barcode and units on hand. Plan seasonal drops with a vendor, expected arrival and release date, and list the units ordered and received per variant. Staff sign in with their own accounts. Show a size grid on each style page, a drop calendar, a broken-sizes list and sell-through by size.

Overview

Who this clothing inventory app is for

A boutique never stocks just “the linen shirt.” It stocks that style in three colorways and six sizes — 18 SKUs that sell at different speeds. In a spreadsheet, the black medium sells out in a week while the sage XS waits for the end-of-season sale, and next season’s order repeats the same size split. A clothing inventory app built with Netiva keeps styles, variants, drops and sales figures together, so owners and buyers can see stock for every size and color, what lands in the next drop and how each size sold through before they reorder.

Key features

What your clothing inventory app can do

  • Size-and-color stock grid

    Each style opens as a grid with sizes across and colorways down. Every cell is a variant record with its own SKU, barcode and on-hand count, so a gap in the size run is visible at a glance.

    • Sizes shown in the style’s own scale order, from XS to XL or 26 to 34 waist
    • Sold-out and single-unit cells highlighted
    • A swatch photo per colorway, uploaded once and shown beside its row
    • Totals on hand per style, colorway and size

  • Seasonal drop planner

    Plan every drop with its vendor or factory, expected arrival and release date, then list the size run ordered for each variant. When cartons arrive, staff record what came in against the plan.

    • Drops by status: Planned, On order, Received or Live
    • Ordered versus received units for every size
    • Late drops flagged once the expected date passes
    • An email to the buyer a week before each release

  • Sell-through by size

    The report divides units sold by units received for each style, colorway and size, so the next buy follows what customers actually took home rather than last season’s guess.

    • Sell-through by season, category, style and size
    • A four-week figure saved for every drop line by a scheduled job
    • A suggested size split for the rebuy, each size weighted by its sell-through on the last drop
    • Slow sellers listed as end-of-season sale candidates

  • SKUs that match your Netiva store

    The app uses the same variant SKUs as your Netiva store catalog, so a style reads the same in the stockroom and at checkout. The store keeps sizes, colors, SKUs and per-variant price and stock of its own, and holds new products in Draft.

    • One SKU per size and colorway, written the same way in the app and the store
    • New-season products kept in Draft until you mark them Active
    • A release-day checklist of the SKUs to flip from Draft to Active
    • Stock counted separately on each side, tied together by the SKU

How it works

From prompt to a live clothing inventory app

  1. Describe your line

    Tell the agent which seasons you run, how your sizes are scaled and whether drops come from wholesale vendors or your own factory. It drafts collections for styles, variants, drops and drop lines.

  2. Build out the variants

    Add styles in the collection grid, then ask the collection assistant to draft a variant row for every size and colorway of a style. Review the SKUs before you keep the rows.

  3. Check a style in the preview

    Open a style grid and a drop in the live preview. Annotate anything that looks wrong, such as sizes in the wrong order, and the agent fixes it while you watch.

  4. Go live before the next drop

    Publish with one click, have staff create their sign-ins and turn on the buyer’s release reminders. If a later change breaks the grid, roll back to an earlier checkpoint.

Examples

Ways teams use it

  • A multi-brand boutique

    The owner buys from several wholesale labels twice a year. Before market week, the owner reviews each label’s sell-through by size and trims the sizes that sat on the rail, rather than repeating last season’s size run.

  • A direct-to-consumer label with monthly capsules

    A two-person brand releases a small capsule each month through its Netiva store. The drop calendar tracks factory dates, and each capsule’s products wait in Draft until release morning.

  • A denim and workwear shop

    Waist and inseam sizes turn one jean style into a grid with dozens of cells. Staff see exactly which combinations, such as 32×30, are gone, and the buyer restocks those before the weekend.

Good to know

Before you build

  • Sales still come from your register

    The app doesn’t ring up sales. Sold-to-date numbers come from your POS’s sales-by-SKU report, entered weekly, or from its API if your provider offers one, and on-hand counts follow from them. Returns and damaged stock drift until someone counts the rail and corrects the cell.

  • Store stock and app stock

    A Netiva store keeps its own per-variant stock, and so does the app; the SKU is all the two share. Name one of them as the record staff work from — most shops pick the app’s count and lower it when the store ships an order — and write that rule down for whoever packs parcels.

  • Barcodes for your own label

    If your label uses barcodes, each size-and-color combination needs its own GTIN, which US brands get from GS1 US. The app keeps those numbers on file but doesn’t issue them. Multi-brand boutiques can usually use the UPC on each vendor’s hang tag.

  • Garment labels are still your job

    In the US, most garment labels must show fiber content, country of origin and the name or RN of a responsible company, and the FTC’s Care Labeling Rule adds care instructions. The app can hold that text for each style but doesn’t check your labels.

FAQ

Questions about building a clothing inventory app

How do I track clothing inventory by size and color?

Store each design once as a style, then give it one variant for every size and colorway, each with its own SKU and on-hand count. The style page lays those variants out as a grid, sizes across and colors down, so a sold-out medium or a single remaining XL stands out. Filtered views list the same variants by season, category or status.

What is sell-through, and how does the app work it out?

Sell-through is the share of what you received that has sold: units sold divided by units received. If a drop brought in 24 mediums and 18 have sold, that size is at 75%. The app calculates it for each drop line, and a scheduled job saves the figure four weeks after release, so you can compare drops that launched at different times.

Can it handle carryover styles as well as seasonal drops?

Yes. Give core styles the season Core and seasonal ones a code such as SS27 or FW26. A carryover style keeps the same variants and SKUs, and each restock is added as a new drop line. Sales by SKU fill the oldest line that still has units left before they count against the newer one, so a restocked style keeps one history of orders, arrivals and sell-through.

Does the app work alongside a Netiva online store?

Yes. Netiva’s store catalog handles products with size and color variants, SKUs and per-variant price and stock, plus checkout. Give the app the same SKUs so both describe the same items, and keep new drop products in Draft until release day. The two keep separate per-variant stock, though: pick one as the count staff work from, and adjust it when the store ships an online order.

How do I get my current styles into the app?

Add styles in the collection grid, which works like a spreadsheet, or describe a style to the collection assistant and it drafts the variant rows for you to review. Bulk edits help with repetitive work, such as filling in a season code or reformatting SKUs across many rows. Start with the current season’s styles and add older stock as you count it.

Can I move the clothing inventory app’s code somewhere else later?

Yes. Netiva writes clean, framework-standard code that you can read in the code view, edit and export whenever you like, with no proprietary runtime. Every change the agent makes is checkpointed, so you can compare versions and roll back if an update to the size grid or the reports doesn’t work out.
