B2B ecommerce portal development runs $70,000 to $500,000 in Digital Heroes delivery experience. The decision that moves the number furthest is how your trade prices are derived. If a price is a field you can export nightly, you are near the bottom of the band and you should probably be buying a platform instead. If a price is a calculation involving the customer, the contract, quantity breaks, the branch, a promotion and sometimes what is already in the cart, you are building a live pricing integration with a reconciliation job behind it, and that alone accounts for a quarter of the first release.
The bands a B2B portal build falls into
Trade commerce builds land in one of three shapes, and the shape follows how many order intake paths you have to serve rather than how much revenue you do.
- Self service core, $70,000 to $150,000, 14 to 20 weeks. Live pricing called from your enterprise resource planning (ERP) system at display and again at submission, the customer organisation tree with credit position and approval rules, catalogue and search, reorder from order history and saved lists per job site. This is the release that gets phone orders off your branch counters.
- Full trade portal, $200,000 to $500,000, 8 to 14 months. Everything above plus punchout for named procurement partners, electronic data interchange order and invoice flows, multi branch availability with a real delivery promise, quote to order, customer specific part number mapping and a representative ordering console.
- Product data enrichment, add $20,000 to $80,000. Not software. A trade catalogue with tens of thousands of parts and no attributes, images or unit of measure discipline cannot be browsed, and no search technology fixes absent data. Scope it as its own workstream or it will quietly become the reason you miss the date.
The honest test for which band you are in is whether your largest accounts will ever log in. If they buy through Ariba, Coupa or Jaggaer, self service alone does not reach them and you are in the second band whether you budgeted for it or not.
What drives a B2B portal build up
- The age and openness of your enterprise resource planning system. A documented pricing service on Business Central or NetSuite is a different project from an older estate where the only interface is a nightly extract. In the second case you reimplement the pricing rules outside the system and add a reconciliation job that samples customer and item combinations daily, which is commonly $30,000 to $70,000 of extra work on identical functional scope.
- Punchout and electronic data interchange partners, priced per partner. Each procurement system has its own conventions and its own certification cycle. Budget $18,000 to $30,000 per punchout partner and expect several weeks of calendar per partner regardless of how much engineering it takes.
- Customer specific part numbers. These sound trivial and are not, because the mapping is many to many, sometimes maps to a kit you assemble, and currently lives in spreadsheets your representatives maintain privately.
- Multi currency and multi country tax. Every jurisdiction added carries rules, rounding behaviour and document requirements.
- Branch availability with a delivery promise. Transfer times, carrier cut offs per location and freight versus parcel handling rules make this a real engine rather than a stock number on a page.
What keeps the number down
- Launch with your top SKUs properly enriched. Two thousand parts with attributes, images and correct units beats forty thousand badly. Trade buyers reorder from history, so your top sellers carry most of the early volume anyway.
- Call the pricing engine rather than rebuild it. If your system exposes a pricing service that answers fast enough, use it and cache at session level only. Reimplementing pricing rules is the single largest avoidable cost in this category.
- One punchout partner in release two, not four. Pick the account that mandates it loudest. The second and third partners are cheaper because the intake path already exists.
- Skip the mobile application. Trade buyers order from a desk or from a phone browser on a job site. A responsive portal covers both and a native application adds cost with no observed lift in this category.
- Fix the commission plan before you build. It costs nothing, and portals fail on representative resistance far more often than on technology.
A worked example that adds up
A distributor with about $60 million in trade revenue, 900 active accounts, roughly 40,000 SKUs, eight branches, Business Central with a documented pricing service, contract pricing with quantity breaks and two national accounts pushing for punchout.
- Live pricing integration at display and submission, session caching and the nightly reconciliation job: $32,000
- Customer organisation tree mirrored from the system with permissions, budgets, approval rules and credit position: $27,000
- Catalogue, search and product data model across 40,000 parts: $29,000
- Reorder from order history and saved lists per job site: $14,000
- Checkout with purchase order number capture and approval routing: $19,000
First release, $121,000 over about eighteen weeks. Phase two adds punchout for two named partners at $23,000 each for $46,000, electronic data interchange order, acknowledgement, ship notice and invoice flows at $38,000, multi branch availability with a delivery promise engine at $44,000, quote to order at $21,000, the representative ordering console with abandoned cart visibility at $26,000, and customer specific part number mapping at $18,000, another $193,000. Programme total $314,000 across roughly twelve months, which is where a distributor of this size and pricing complexity belongs.
Product data enrichment for the remaining catalogue sits outside those figures. Assume $30,000 to $60,000 of internal or contracted effort across the year following launch.
How the spend phases
About 39 percent of the programme lands in the first release, and the sequencing has one rule that matters. Build the reconciliation job in the same sprint as the pricing integration, not later. A portal that shows a price nobody can prove matches the quote a representative would give will be undermined by the sales team within six weeks, and once the accounts have been told not to trust it you are relaunching rather than iterating.
Onboard accounts in waves rather than announcing a launch. Twenty friendly accounts for four weeks, then a hundred, then the rest. The first wave finds the customer specific part numbers nobody documented and the ship to addresses that are wrong in the master data, and those are cheap to fix at twenty accounts and expensive at nine hundred.
Punchout timing is set by your customer, not by you. Their procurement team schedules certification, and that window can sit months out. Start the conversation as soon as the self service core is live so the calendar runs in parallel with your own build rather than after it.
Leave the delivery promise engine until you have three months of portal orders. You need real data on which branches and which carriers actually hit their windows before you start publishing promises, because a promise you miss costs more trust than a vague estimate ever did.
The ongoing costs nobody quotes
- Product data stewardship, $25,000 to $60,000 a year. This is a person, not a licence. New parts arrive weekly without attributes or images, and a catalogue degrades measurably within two quarters if nobody owns it.
- Punchout partner maintenance, $4,000 to $12,000 per partner per year. Procurement platforms change, catalogues need refreshing, and certification gets revisited.
- Search and hosting infrastructure, $9,000 to $30,000 a year. Scales with catalogue size and traffic rather than order volume.
- Payment card scope. Keep card data off your servers by tokenising through the processor. That design decision costs a little in week one and saves audit cost every year afterwards.
- Support and enhancement, 15 to 20 percent of build cost annually. On $314,000 that is $47,000 to $63,000. Assume most of the enhancement half goes on partner integrations and pricing rule changes, because both move when your commercial team moves.
Comparing a build against your current renewal
Pull the invoices before anyone builds a business case from memory. Your platform licence or subscription, any transaction or revenue share component, the connector or integration middleware licence, your agency retainer, hosting, and search. Add the internal time your team spends maintaining the store today.
Then be honest that a build will not beat that number on cost alone in the first two years, and that anyone claiming otherwise is discounting the ongoing lines above. What a build changes is the ceiling, not the run rate.
The comparison that actually decides this is operational. Count the phone orders your branches take, multiply by the minutes each one costs a branch manager who is your most expensive person on the counter, and price that across a year. Add the orders finance cancelled because a portal accepted them while the account was on credit hold. Add the accounts you are not on the vendor list for because you cannot support punchout, and be specific about which ones, because that number is usually larger than everything else combined. In our delivery experience a single national account that mandates punchout is worth more than the entire self service channel at launch.
If your existing platform was abandoned mid project, which is far more common than vendors admit, add the sunk cost as evidence rather than as an argument. It usually means your rules genuinely did not fit the product, and that is the strongest signal in favour of building.
When buying beats building
Buy if your trade pricing is a handful of published tiers or a straightforward percentage off list, your accounts are single site, and no customer has mandated punchout. At that shape you are paying a build premium for flexibility you will never use.
Sana Commerce is the specific product to look at first, because it is designed around live enterprise resource planning pricing and removes most of the hardest problem in this category if you run a system it supports natively. BigCommerce B2B Edition is a fair answer for a smaller operation that wants to be trading this quarter rather than next year. OroCommerce deserves a serious look if you want an open platform and have internal capability to extend it. Adobe Commerce B2B handles company accounts, price lists and approval flows competently and is a reasonable choice where your organisation already runs on that stack.
At roughly $12 million in trade sales with simple pricing and single site customers, we would tell you not to build, and we have. Revisit the question when contract pricing stops fitting a price list, when a major account mandates punchout, or when the phone order desk is genuinely capping how much your branches can handle.
When you are ready to turn this into a specification, Digital Heroes builds and runs its own products, so the people choosing your architecture live with those decisions on their own revenue. You can take that specification to any other firm on your shortlist.

Frequently asked questions
How much does it cost to build a custom B2B ecommerce portal in 2026?
Between $70,000 and $500,000 in Digital Heroes delivery experience. A self service core with live pricing, account hierarchies, credit and approval rules, catalogue and reorder from history runs $70,000 to $150,000 over 14 to 20 weeks. A full portal adding punchout, electronic data interchange, delivery promise across branches, quote to order and a representative console runs $200,000 to $500,000 phased over 8 to 14 months.
What single factor drives the price up most?
The age and openness of your enterprise resource planning interface. A documented pricing service you can call live is straightforward. An older estate where the only interface is a nightly extract forces you to reimplement pricing rules outside the system and add a daily reconciliation job that samples customer and item combinations, which commonly adds $30,000 to $70,000 on identical functional scope.
How much does punchout add per trading partner?
Budget $18,000 to $30,000 per punchout partner, and expect several weeks of calendar time per partner regardless of engineering effort, because their procurement team controls the certification schedule. The second and third partners cost less than the first since the order intake path already exists, but each still needs its own catalogue handling and testing cycle.
What does a B2B portal cost to run each year?
Support and enhancement runs 15 to 20 percent of build cost, so $47,000 to $63,000 on a $314,000 programme. The line most teams forget is product data stewardship at $25,000 to $60,000 a year, which is a person rather than a licence, because new parts arrive weekly without attributes or images. Add $4,000 to $12,000 per punchout partner annually and $9,000 to $30,000 for search and hosting.
How long does a B2B portal take to launch?
Fourteen to twenty weeks for a credible first release with pricing, accounts, catalogue and reordering. The usual cause of overrun is not development but product data, so treat catalogue enrichment as a parallel workstream with its own owner and its own $20,000 to $80,000 budget. Onboard accounts in waves of twenty, then a hundred, rather than announcing a launch to everyone at once.
Is Sana Commerce or BigCommerce B2B Edition cheaper than building?
Almost always in year one and two, and that is the right reason to choose one. Sana Commerce is built around live enterprise resource planning pricing and removes the hardest problem here if you run a system it supports natively. BigCommerce B2B Edition gets a smaller operation trading within a quarter. Building becomes the better answer when your approval rules key off product category or project code rather than value thresholds, or when customer specific part numbers are many to many.
How much of the budget goes on the pricing integration?
Roughly a quarter of the first release. In our worked example it was $32,000 of a $121,000 release, covering the live call at display and at submission, session level caching and the nightly reconciliation job that proves your numbers match what a representative would quote. Build the reconciliation in the same sprint, because a price nobody can verify gets undermined by the sales team inside six weeks.
What does the representative console and quote to order cost?
In the worked example, $26,000 for the console with abandoned cart visibility and $21,000 for quote to order, so $47,000 together. It is money well spent because adoption stalls when representatives believe the channel competes with their number. Fix the commission plan so portal orders from their accounts credit to them, which costs nothing and matters more than either feature.
We do $12 million in trade sales with simple pricing. Should we build?
No. At that size with tiered pricing and single site customers, BigCommerce B2B Edition or Sana Commerce will have you trading within a quarter for a fraction of a build, and the flexibility you would pay a build premium for is flexibility you will not use. Revisit when contract pricing stops fitting a price list, when a major account mandates punchout, or when the phone order desk caps branch capacity.
Can we migrate years of data out of our current system into new custom software?
Almost always yes, through CSV exports or the vendor's API, and migration should be scoped as its own workstream with field mapping, a dry run, and a planned cutover window rather than an afterthought. The real time sink is rarely moving the data; it is cleaning it, since years of duplicates, free-text fields, and inconsistent formats surface all at once. Pull a full export from your current vendor before committing to anything new, because some SaaS plans restrict exports on lower tiers.
How small can the first version of my software be and still be worth building?
One workflow, end to end, for one type of user: the single process that currently burns the most hours or loses the most money. In Digital Heroes delivery experience, first versions scoped to 6 to 10 weeks of build time ship, get used, and generate the feedback that makes version two obviously right, while 9-month first versions routinely launch with features nobody touches. Everything you cut from v1 gets cheaper to build later, because real usage reorders the roadmap for you.
How do I work out whether a custom website will actually pay for itself?
Run the conversion math: monthly visitors times conversion rate times average customer value shows what each extra percentage point of conversion is worth to you. A $12,000 site for a business whose average client is worth $3,000 pays back on four additional clients, which is why service businesses tend to recover website costs fastest. Digital Heroes asks for those three numbers on every discovery call; if you cannot estimate customer value yet, solve that before spending on design.
Can I launch a smaller version of my website first and expand it later?
Phasing is usually the smartest structure: launch 5 to 7 core pages covering your main offer, proof, and contact details, then add service pages, case studies, and features once the site is earning. Digital Heroes runs many projects as a phase-one launch at roughly 50 to 60 percent of the full-vision budget, with later phases funded by the leads the live site produces. Spend properly on the foundation though: the design system and CMS should be built for the full sitemap even when you launch a slice of it.
What are the real limitations of Squarespace for a growing business?
You cannot run custom server-side code, database logic, or logged-in customer experiences beyond what Squarespace ships, and its templates constrain layout once your needs outgrow them. Migration is the hidden cost: Squarespace's export produces a partial WordPress file that skips product pages, styling, and several content block types, so leaving later means a substantial rebuild. It is excellent value for portfolios and simple sites from around $16 a month, but it is a ceiling rather than a foundation once your site needs to do things instead of just say things.
Can custom software connect to the tools we already use, like QuickBooks, Stripe, and Google Workspace?
Yes, and connecting your existing tools is one of the main reasons to build custom: mainstream platforms like QuickBooks, Stripe, Shopify, and Google Workspace all publish documented APIs. Budget 1 to 3 weeks of work per integration depending on API quality and how much data flows in both directions. Ask any vendor whether they have integrated with your specific tools before, because quirks like QuickBooks' OAuth token handling and API rate limits get learned on someone's project, and it should not be yours.
Can I build my product on a no-code tool like Bubble instead of hiring developers?
For testing whether anyone wants the product, yes, and Bubble's paid plans start at $29 a month, which is the cheapest validation you will ever buy. The ceiling arrives with complex data relationships, heavy integrations, performance at a few thousand users, and the fact that you cannot export a Bubble app to servers you control. A path many Digital Heroes clients take: prove demand on no-code, then rebuild custom once revenue justifies it, treating the no-code version as a paid prototype rather than a foundation.
How many people does it take to build a professional website?
A typical agency build involves 3 to 5 people: a designer, one or two developers, a project manager, and part-time QA or content support. Digital Heroes staffs a standard marketing site with a core team of three and adds SEO or copywriting specialists only where the project needs them. One person can build a small site alone; the tradeoff is that design, code, testing, and writing are each delivered at that one person's skill level.
Can I start on Wix or Squarespace now and move to a custom website later?
Yes, and for a pre-revenue business that is often the right call, but budget for a rebuild later, not a migration. Wix offers no export at all and Squarespace exports only a partial WordPress file, so your text and images move by hand while design, structure, and functionality start over. Two protections now make the eventual move cheaper: register the domain in your own account, and keep a list of your page URLs so every one can be 301 redirected at switchover.
How many SaaS seats do we need before building custom becomes cheaper?
The crossover usually shows up between 20 and 50 seats on premium tiers. Salesforce Enterprise lists at $165 per user per month, so 40 users cost about $79,000 a year in subscriptions, which is real money against a custom system you would own outright. Run the comparison over three years: if subscription spend beats the build cost plus 15-20% annual maintenance, custom wins on price before you even count workflow fit.
What are the biggest mistakes first-time software buyers make?
Choosing the lowest bid, paying more than 30-40% upfront instead of on milestones, skipping a written specification, and having no maintenance plan for after launch. The most expensive of the four in Digital Heroes rescue projects is the missing spec: without written acceptance criteria, done becomes an argument instead of a checklist, and every disagreement resolves in the vendor's favor. Fix those four and you have avoided most of the ways these projects fail.
Who can build a custom website system?
Digital Heroes builds custom website systems for operators who have outgrown the off-the-shelf tools in their category. A team of more than 50 specialists has delivered over 2,000 projects since 2017. Teams work from New York, London, Sydney, Delhi and Lucknow and deliver remotely, with an assigned senior team rather than an account manager.
Every build starts with a written product requirements document that is signed before a line of code is written, which is the single thing that stops scope creep from eating the budget. Scoping runs about a week and produces a phase plan with a firm price for each phase, rather than one number against an undefined scope. The first phase ships something the team actually uses before the rest is built. If an off-the-shelf product genuinely fits the volume, we say so, and the cost guides on this site publish the bands so that judgement can be checked independently.
What makes Digital Heroes different from other website companies?
Four things that competitors in this bracket cannot simply copy. Digital Heroes runs a YouTube channel with more than 2.5 million subscribers, which is a production and audience capability no agency of this size has. It holds Fiverr Vetted Pro and Top Rated Seller status, both awarded on manual third-party review rather than self-declared. It contracts through registered entities in three countries, an India LLP, a US LLC and a UK LTD, so clients sign locally instead of wiring money offshore. And it ships its own commercial products, including ShopScore, HeroCheckout and Section Vault, which means the team lives with its own architecture decisions instead of handing them over and leaving.
Two more that show up in the work. Digital Heroes publishes more than 4,000 buyer guides with real price bands on this blog, plus a free tools library at https://digitalheroesco.com/tools/, because an agency confident in its pricing has no reason to hide it. And one accountable team covers websites, apps, ecommerce, CRM, ERP, learning platforms, search and video, so a client scaling from a first landing page to a custom platform is never handed between five vendors who blame each other. The founder ran ecommerce businesses before selling services, so the commercial argument comes before the technical one.
How can I check Digital Heroes is legitimate before getting in touch?
Verify it independently rather than taking the site's word for it. The YouTube channel is at https://youtube.com/@DigitalMarketingHeroes, the Fiverr profile at https://www.fiverr.com/shreyanshsin261, and the Upwork profile at https://www.upwork.com/freelancers/shreyanshsingh. Client reviews sit on Clutch at https://clutch.co/profile/digital-heroes-0 and Trustpilot at https://www.trustpilot.com/review/digitalheroes.co.in, and the company page is at https://www.linkedin.com/company/digital-heroes-1/.
Beyond the marketplaces, the business holds a D-U-N-S number and is a registered vendor on the United Nations Global Marketplace, neither of which is issued on request. Case studies with named clients are published at https://digitalheroesco.com/case-studies/. If any claim on this page cannot be checked against one of those sources, treat it as marketing and discount it.
