“How much for a custom WooCommerce store?” is the first question every merchant asks — and most agencies answer with “depends”. This guide gives actual ranges from projects we and our peers deliver, what moves the price, and where money is wasted.
The honest price table
| Engagement | Typical range (USD) | Timeline |
|---|---|---|
| Theme customization on an existing lean theme | $2,000 – $6,000 | 1–3 weeks |
| Custom B2C store build (theme + full Woo setup) | $8,000 – $18,000 | 4–8 weeks |
| B2B build: pricing rules, quotes, VAT invoicing | $12,000 – $25,000+ | 6–12 weeks |
| Custom plugin / feature | $1,500 – $4,000 | 1–3 weeks |
| ERP / CRM / marketplace integrations | $2,000 – $15,000+ | 2–10 weeks |
What actually drives the price
- B2B logic. Role-based price lists, quote workflows and negotiated accounts are custom engineering — consumer plugins only fake them.
- Integrations. Every external system (ERP, PIM, shipping carriers, marketplaces) adds discovery, API work and failure handling.
- Content migration. Product data quality dictates import effort — 5,000 clean SKUs cost less than 2,000 messy ones.
- Design originality. “Distinctive, not a template” is more design hours, and worth it for brands with real differentiation.
Where money gets wasted
The two most common wastes we see in inherited projects: (1) a $60 multipurpose theme bloated into a $10,000 pile of child-theme CSS patches, and (2) nine plugins stacked to approximate one custom module. Both cost more to maintain than the honest custom build would have — see what plugin stacking leads to.
How to scope smart
- Start with the free audit — know your baseline before pricing anything
- Phase the build: catalog + checkout first, integrations second, nice-to-haves third
- Ask for acceptance criteria in the quote, not day estimates
- Insist on staging demos — weekly, not “when it’s done”
- Confirm who owns the code (answer: you, always)
Our WooCommerce development service and custom development service both follow this model — fixed quotes from written scopes. The free site audit is the no-cost first step.
Frequently asked
Hourly billing rewards slowness. We scope, quote fixed, and absorb estimation risk — you approve outcomes, not timesheets. For stores where design and workflow are the brand: yes, measurably — in speed, maintainability and conversion. For testing a product idea on a budget: start with a good lean theme, and graduate when the model is proven.Why is custom work quoted fixed-price instead of hourly?
Is a $8k custom build really better than a $300 theme setup?
