What a B2B website development company actually charges

How to buy B2B web development without guessing

1. Separate the build from the run. A quoted build price almost never includes the year that follows it. Ask for the launch figure and the monthly figure side by side, and ask what the monthly covers: hosting, security patching, content changes, or only uptime monitoring. Two firms quoting the same build can differ by a factor on the run.
2. Price the integrations, not the pages. Page count is the cheapest part of a B2B build. The cost sits in the connections: CRM field mapping, marketing automation, gated asset delivery, single sign-on, ERP product data. Ask which integrations are in scope, who owns the API credentials, and what happens when the vendor on the other side changes their schema.
3. Ask who writes the words. Many development quotes assume the client supplies final copy, then stall for months when it does not arrive. Establish whether writing, technical review and approval sit with the agency or with you, and put a named owner and a date against each page before the build starts.
4. Get ownership in writing before kickoff. The repository, the domain registration, the DNS, the analytics property and the licences for any commercial plugin or theme should end up in accounts you control, with the agency granted access. Confirm it in the contract rather than discovering it during a handover you did not plan.

What moves the price

Scope moves it most, and in B2B scope usually means systems rather than screens. A marketing site with a contact form is priced in one band; the same site with lead routing into a CRM, a gated resource library, account-based landing page variants and a partner portal is priced in another, because each one adds integration work, testing and a failure mode someone has to own. Complexity of the sales process is the honest proxy for cost: the more people who have to be convinced before a deal closes, the more the site has to do.

Two other factors move it quietly. The first is the state of what you already have: a migration from an ageing platform carries redirect mapping, content audit and data cleanup that a greenfield build does not. The second is compliance. If your buyers are in regulated sectors, accessibility, data residency, consent capture and security review add real hours, and a quote that omits them is not cheaper, it is incomplete.

Questions that separate a partner from a vendor

Ask what happens in month four. A vendor answers with a support inbox; a partner answers with a named person, a response window and a plan for iterating on what the analytics show. Ask to see a site they built two years ago and still maintain, then look at whether it has evolved or frozen. Ask how they would measure success, and listen for whether the answer is traffic or qualified pipeline.

Then ask the uncomfortable one: what would you refuse to build for us? A firm with a point of view will name something, and the reasoning tells you more about their judgement than any portfolio grid. A firm that says yes to everything is quoting your wish list back to you, and that quote will be revised upward the first time reality intervenes.

Questions people actually ask

What does a B2B website development company cost?

It depends far more on integrations and content volume than on page count. A marketing site with a form sits at the low end of any agency's range, while a build that routes leads into a CRM, gates a resource library and serves account-based variants sits well above it. Ask for the build figure and the ongoing monthly figure separately, because they are quoted separately and only one usually appears in a pitch.

How long does a B2B website build take?

Discovery and content approval, not development, set the timeline in most projects. Builds slip when copy has no named owner and no date. Ask the agency for the critical path and ask which items on it are theirs and which are yours, then staff your side of it before kickoff.

Should the same firm do the build and the SEO?

It can work, and it removes the argument about whose fault a traffic drop is. It also removes the second opinion. If you combine them, insist on separate reporting for build quality and for search performance, so a slow launch cannot be reported as a search win or the reverse.

Who should own the code and the accounts?

You should. The repository, domain, DNS, analytics and any paid licences belong in accounts you control, with the agency granted access. Agencies that resist this are describing a switching cost, and switching costs are a price you pay later rather than a discount you receive now.
