The line between website and software
A website presents and persuades: pages, proof, enquiry paths. Software executes: logins, accounts, workflows, data that changes state. The line is crossed the moment a user expects the site to remember them or a process to complete without a human forwarding emails.
Common crossing points in B2B: trade portals with account pricing, partner platforms, client document exchange, quoting and configuration tools, booking and scheduling, compliance workflows and dashboards. Quartix's partner platform and Universal Gas's dual-market enquiry routing both live on this line.
Why the seam between agencies fails
The standard failure: a brand agency designs screens a development shop then quotes triple for, or a dev shop builds workflows wrapped in an interface buyers do not trust. Each blames the other, and the business pays for the translation layer in both money and months.
The fix is structural, not contractual: have the same senior people design the marketing site and build the software. That is Web Hero's wedge. Rudo-style design agencies stop at the marketing site; Dapper-style marketing agencies stop at campaigns; we design the site and ship the software behind it.
How to phase it without overbuilding
Build the website first with software-grade structure: real data modelling, component systems and analytics. Then add software where measured demand appears, on the same stack. This is how a £4,500 site grows into a portal without a rebuild.
Overbuilding is the opposite risk: shipping a portal nobody asked for. The test is a named user with a weekly pain, stated in their words. No named user, no build.
- Phase 1: marketing site with structured data and measurement (from £4,500)
- Phase 2: the first workflow with a named user and a weekly pain (scoped from £18,000)
- Phase 3: integrations that remove manual steps, priced after technical discovery
Signals you are ready for the software phase
Spreadsheets emailed weekly between you and customers, password-protected PDF dances, manual rekeying between systems, or sales answering identical pricing questions daily. Each is a workflow asking to run through the site. Bring one to a call and we will tell you honestly whether it is a £6,000 integration or a £25,000 product.
