summary: "Store quotes swing from $1,000 to $12,000+ for what looks like the same brief. The real cost drivers are integrations and catalog complexity, not the design."

Two stores can have the same number of pages, the same product count and
wildly different price tags. The design usually looks similar too — a
grid, a product page, a cart. What actually separates a $2,000 quote
from a $20,000 one almost never shows up in a screenshot: it is what the
store has to talk to, and how complicated a single product is to sell.

## The ladder, from simplest to most connected

Template or builder store, $1,000–3,000. Shopify, WooCommerce, a
theme with your logo and products loaded in. You get a working store in
days. What you give up: custom checkout flows, real control over
performance, and any integration the platform's app marketplace does not
already offer. For a small catalog with one payment provider and
standard shipping, this is genuinely enough — do not let anyone sell you
more than you need.

Storefront, from $2,500, live in 4-6 weeks. A designed store with
payments and delivery wired in properly, catalog up to about 50 SKUs.
The fast way to start selling direct and test demand past what a
template can do, without yet needing to sync with internal business
systems.

Full store, $5,000–12,000, a 2-4 month project. ERP or inventory
sync so the site never sells stock that is not there, a customer
account with order history and saved details, promo codes and loyalty
mechanics, hundreds of SKUs, often a configurator for products sold in
variants. This tier is a piece of business infrastructure, not a
marketing page with a cart bolted on.

## What actually multiplies the price

It is not the number of pages, and it is not the visual design. A
five-page store and a fifty-page store can cost the same if the
five-page one has to sync inventory with an ERP in real time and the
fifty-page one does not connect to anything.

The real multipliers are integrations. Each payment provider is
configuration and testing, not a checkbox. Shipping gets expensive fast
once you add multiple carriers, live rate calculation, or international
zones. ERP or warehouse sync is the biggest jump on the list: it means
building a reliable two-way link so stock, prices and order status stay
correct on both sides, and handling what happens when that link fails.
CRM and email platform connections, tax calculation by region, loyalty
and promo logic — each one is real engineering, and each one is a line
that should appear in the quote by name, not folded into "integrations"
as a single vague item.

## Catalog size and product complexity

Product count matters less than product structure. A hundred simple
products with one photo and one price are a straightforward catalog
import. Twenty products with a dozen variants each — size, color,
material, bundle options — are a different build: the catalog needs a
real variant model, and the storefront needs a configurator that shows
the right combination, price and stock for whatever the customer picks.

Configurators are their own budget line. Anything from a simple
size-and-color selector to a build-your-own-bundle tool has to handle
combinations that do not exist, prices that change per option, and
inventory that is tracked per variant, not per product. Quote this
honestly during discovery rather than discovering it mid-build.

## What discovery should surface before you get a number

A quote is only honest if it is built on the actual systems involved.
Before pricing a store, we want answers to a short list: which payment
providers, which shipping carriers and zones, whether inventory lives in
an ERP or spreadsheet today, whether products have variants and how many,
whether promo codes and loyalty points are part of the plan, and who
updates the catalog after launch. Skip this step and the quote is a
guess — and guesses get revised upward once the real integrations
surface during the build, not before it.

## Where we stand

Our own work starts at the storefront tier: from $2,500 for a store
with payments and delivery wired in, $5,000–12,000 for a full build with
ERP sync and promo mechanics, and ongoing development after launch from
$2,000 a month. If you want an honest read on which tier your catalog
actually needs, tell us about your [e-commerce](/services/ecommerce)
plans and we will scope it against your real integrations, not a
generic feature list.
