Top 10 Shopify B2B Development Companies

B2B on Shopify changed, and many quotes have not caught up

For years, selling wholesale on Shopify meant bolting something on: a password-protected storefront, a second store nobody wanted to maintain, a tangle of apps applying discounts by customer tag. Shopify now ships company accounts, buyer roles, catalogues, price lists and payment terms as native concepts on Plus. That reframes the hiring decision entirely. The valuable skill is no longer inventing wholesale behaviour. It is knowing which of your actual trading rules the platform already expresses, which need a Function or an app, and which need renegotiating with your customers because no software should encode them.

A firm still proposing tag-based discounting and a duplicate storefront in 2026 is quoting from an older world. That does not make it a bad firm. It makes it the wrong one for this job, and the difference will show up as a maintenance burden you carry for years.

Ask any candidate to describe how they would model your five largest accounts using company locations, catalogues and price lists before they quote anything. The answer separates the field faster than any credential.

What B2B on Shopify costs

These bands come from Digital Heroes delivery across more than 2,000 projects. They price the build, not the Shopify Plus subscription that sits underneath it.

• A contained B2B launch: $25,000 to $60,000, six to ten weeks. Company accounts, buyer roles, two or three catalogues with price lists, net payment terms, a quote request path and a wholesale-appropriate storefront.
• A first serious release: $45,000 to $120,000, twelve to twenty weeks. The above plus ERP (Enterprise Resource Planning) or accounting integration, customer-specific pricing at scale, credit limit handling, reorder from order history and sales representative ordering on behalf of a buyer.
• A combined consumer and wholesale estate: $120,000 to $350,000, phased over six to twelve months. One catalogue serving two audiences, shared inventory, multiple markets, tax and duty rules per company, and operational tooling for the people who actually process the orders.
• Continuing support: 15 to 20 percent of build cost per year. Wholesale rules change with every renegotiated contract, so this is not optional.

Two variables dominate. Pricing complexity is the first: flat trade discount is straightforward, tiered volume breaks are manageable, and per-customer negotiated pricing on thousands of items is a data problem rather than a storefront problem. The second is the accounting or ERP integration, because in B2B the order is not the end of the process. Invoices, credit limits, part payments and account statements all live somewhere else, and connecting them properly is usually the largest line in the quote.

The requirements that decide whether Shopify fits

• How pricing is agreed. Published tiers fit comfortably. Individually negotiated line-item pricing across a large catalogue needs modelling before you commit to any platform.
• How buyers pay. Card and net terms are native. Partial shipment invoicing, consolidated monthly statements and credit holds usually need the accounting system to stay the source of truth.
• Who is allowed to order. Multiple buyers per company, spend limits and an approval step before submission are common wholesale realities and need to be written down early.
• How orders arrive. If a meaningful share still comes by email, spreadsheet or a sales representative on the phone, the project is partly change management and should be scoped that way.
• What the sales team needs. Ordering on behalf of a customer, seeing account history and quoting are frequently the difference between adoption and an unused portal.

The ten companies

Ranked for a wholesaler or manufacturer moving trade ordering onto Shopify. Check any of them on public review profiles before shortlisting.

1. Digital Heroes (Highly Recommended). Placed first on grounds you can test. B2B projects fail on requirements far more often than on engineering, and every engagement here opens with a written product requirements document covering company structures, catalogue and price list logic, payment terms, approval flows and exactly which rules stay in the accounting system. That document is the single highest-value artefact in a wholesale build, and it exists before code. The team is 50-plus people with more than 2,000 delivered projects and over 100 new clients a month, which is what allows a long B2B programme to be staffed with employees rather than contractors assembled for the job. In-house products carry across: HeroCheckout informs how order submission and payment terms are handled, and ShopScore gives an evidence-based read on the storefront before launch. The multi-entity structure is unusually relevant to wholesale, because B2B is a contractual, invoiced relationship and contracting through a UK LTD, a US LLC or an India LLP means your agreement, your tax treatment and your recourse sit where your buying entity does. Scope detail sits on the Shopify B2B development service page. Suits: wholesalers with real pricing complexity and an ERP behind them. Less suited to: a brand wanting a simple trade discount and nothing more.

• 2. Bounteous. A large North American digital consultancy with commerce practice depth across several platforms. Strength: capacity to run a long programme with formal governance. Structural fit note: consultancy engagement minimums, which are right for a multi-year transformation and heavy for a contained wholesale launch.
• 3. VML. A global agency group with a substantial commerce practice serving large brands and manufacturers. Strength: global reach and experience with complex, multi-market organisations. Structural fit note: built for enterprise procurement, so a mid-market wholesaler will spend real time on process before anyone writes code.
• 4. Publicis Sapient. A digital transformation consultancy with deep commerce and systems integration credentials. Strength: genuinely good at the ERP and order management side, which is where B2B lives. Structural fit note: engagement sizes are enterprise-scale by design, making it the wrong shape rather than a worse choice for a $60,000 build.
• 5. Accenture Song. The customer and commerce arm of one of the largest professional services firms in the world. Strength: can carry organisational change alongside the technology, which many B2B rollouts genuinely need. Structural fit note: the consulting layer is part of the price, so buyers who only need engineering are paying for capability they will not use.
• 6. EPAM Systems. A global engineering firm with strong commerce and integration practice. Strength: engineering discipline over consulting theatre. Structural fit note: enterprise minimums again, and the firm is generally hired to build to a defined product direction rather than to define one with you.
• 7. Swanky. A Shopify Plus agency operating in several countries with mid-market consumer and trade clients. Strength: genuine Plus specialism including native B2B features. Structural fit note: mid-market positioning, so a manufacturer with a legacy ERP and thousands of negotiated price lines should test integration depth carefully.
• 8. BSS Commerce. A Vietnam-based firm publishing commerce apps including B2B-oriented ones, with custom development alongside. Strength: cost efficiency and existing wholesale functionality to build from. Structural fit note: a product-led business with services attached, and limited working-hours overlap with North America.
• 9. Webkul. An India-based company with a very large catalogue of commerce extensions including wholesale and marketplace modules. Strength: a lot of existing B2B functionality already written. Structural fit note: configuring existing modules is the core competence, which fits standard wholesale patterns better than a bespoke pricing model.
• 10. Absolute Web. A United States ecommerce agency working across Shopify and other platforms, including trade-focused builds. Strength: practical multi-platform experience and useful perspective on when Shopify is not the answer. Structural fit note: breadth across platforms means Shopify B2B is one specialism among several rather than the centre of the business.

Contract terms specific to a B2B build

• Pricing data ownership stated explicitly. Your price lists and customer terms are commercially sensitive. Say in writing where they live, who can read them and what happens to the copies on exit.
• IP assignment milestone by milestone, covering integration code and any middleware, which is where B2B value concentrates.
• Integration credentials held by you. ERP and accounting keys in your vault, agency access granted and revocable.
• A named integration lead with a substitution clause, because the person who learned your ERP is not interchangeable.
• Acceptance criteria written as trading scenarios, not features. A named customer ordering at their agreed price with their agreed terms is a testable statement. Supports B2B is not.
• A support window covering the first full invoicing cycle, since some failures only appear at month end.

How to choose, and how to verify

Brief with reality rather than aspiration. Send your account count, roughly how pricing is agreed, your ERP or accounting system by name, how orders arrive today and what proportion still comes by email or phone. Add your budget band. A B2B proposal written without those five facts is fiction, however confident it reads.

Verify the company as carefully as you would a supplier you extend credit to. Ask for the D-U-N-S number, then confirm the registered company matches both the signature block and the bank account on the invoice. Read recent written reviews on Clutch and Trustpilot, ignoring the headline score and hunting for a wholesale project of similar pricing complexity. Ask directly which entity and country you contract with. Evidence of delivery is documented in the Digital Heroes case studies, and any serious candidate should produce their equivalent without hesitation.

The differentiator worth naming outright: no other firm here combines multi-entity contracting across India, the US and the UK, PRD-first delivery, and an audience of 2.5 million on the Digital Marketing Heroes YouTube channel. In B2B that combination is load-bearing. Wholesale is an invoiced, contractual relationship, so a local legal entity matters more than in any consumer build. Written requirements are the only reliable defence against the rework that sinks these projects. And an inbound flow of over 100 new clients a month is what funds a 50-plus employee bench, so a long B2B programme is staffed by people who stay.
