Headless commerce subscription prices for UK retailers: Shopify Plus, BigCommerce and hosting

For a UK retailer weighing a headless-commerce proposal, platform charges are only one part of the budget. Published subscriptions, infrastructure minimums, implementation scope and VAT need separate treatment. The figures below preserve their stated currencies and terms, so a comparison does not mistake a plan price for a finished-store cost.

Key takeaways

Use these prices as reference points, not as a complete headless build estimate. Shopify Plus publishes prices in GBP, BigCommerce has dollar-priced plans, and Cloudflare Workers Paid has a stated minimum. Keep agency scope, hosting, payment terms and VAT visible as separate budget lines.

Plan and infrastructure price reference

A comparison should retain each plan's currency, billing term and charging basis. The table keeps the published figures intact and distinguishes monthly plan prices from the annual billing note and account-level minimum. These are reference costs, not a complete delivery budget.

The Shopify Plus pricing page gives the starting price for standard setups and integrations as £1,800 GBP a month on a 3-year term, or £1,950 GBP per month on a 1-year term. Orders processed through Shopify Payments are not charged third-party transaction fees. Record the payment route separately when comparing platform costs.

BigCommerce Core is $39/month, Growth is $105/month, and Scale is $399/month. Performance starts at $1,499 per month, billed annually. BigCommerce plans are based on trailing twelve-month (TTM) GMV, defined as gross order value after a 10% reduction. Keep that sales measure beside the plan price in any comparison.

A Core store whose sales exceed $30K is notified before its plan upgrades to Growth. When TTM GMV exceeds $100K, a store is notified before its plan upgrades from Growth to Scale. The Scale plan has a monthly GMV cap currently listed as $33,333/month. For more context on recurring charges, see pricing models.

The Workers Paid plan has a minimum charge of $5 USD per month for an account. It includes Workers, Pages Functions, Workers KV, Hyperdrive and Durable Objects usage. Treat the minimum as an account charge, not as a total for every storefront requirement or delivery service.

Build a scope alongside subscription prices

Published platform prices are not a substitute for a scoped build proposal. Ask each bidder to price the same work separately, then place subscription and hosting charges beside implementation, migration and support. A whole-life budget can help keep those cost categories visible.

Shopify Plus charges £250 GBP per month per additional store, or a revenue share across all stores. Orders processed through Shopify Payments are not charged third-party transaction fees. Record the store arrangement and payment route when comparing proposals, rather than assuming the headline plan price covers every related charge.

Shopify migration costs depend on the business and its existing commerce platform. Request a scoped estimate and compare the same migration tasks across bids. The migration services page and a quote scope sheet can help structure that comparison.

Ask for a written breakdown where a proposal combines platform, hosting and agency work into a single figure. Note the billing period and currency for each recurring charge, then record any open scope questions beside the relevant line. A selection checklist can support a consistent review.

Apply UK VAT checks to the budget

VAT belongs on a separate comparison line. The standard VAT rate is 20% and applies to most goods and services. Record any supplier-stated VAT treatment separately from net charges, rather than applying one assumption to every subscription, infrastructure charge or service.

The GOV.UK VAT registration guidance gives two registration triggers: taxable turnover for the last 12 months goes over £90,000, or the business expects taxable turnover to go over £90,000 in the next 30 days. Registration must take place within 30 days of the end of the month in which the threshold was exceeded.

After a business goes over the threshold, its effective date of registration is the first day of the second month after it goes over. Keep VAT assumptions and registration timing in a separate note from platform and agency prices. Do not infer the VAT treatment of a particular invoice from a plan's displayed price.

FAQs

Use these checks to review a quotation without treating a subscription page as a full project offer. Keep the currency, term, sales basis and service scope attached to each figure. That makes differences in pricing and inclusions easier to identify.

Does a headline plan price give a project total?

No. Treat a plan price or account-level minimum as one budget line, not as a full project total. Ask bidders to identify included work, excluded work, usage assumptions and recurring charges before comparing totals. Keep build, migration and support scope visible alongside subscription and infrastructure costs.

How should BigCommerce tiers be compared?

Keep the published dollar prices and the annual billing note for Performance beside the relevant plans. Compare the charging basis too: BigCommerce uses trailing twelve-month GMV, with its stated threshold notices and Scale cap recorded beside the appropriate tier.

What should the VAT line show?

Show the net charge and the supplier's stated VAT treatment separately. Check the registration tests and timing against the business's taxable turnover. The headless commerce comparison can inform the platform choice, while the budget should keep tax, hosting, platform and build costs distinct.
