SPP (2025): custom client portal $20k–$50k initial development + $10k–$25k/yr maintenance; Agency Handy $25k–$60k all-in over 6–12 months
Summary
Claim: SPP (2025), verbatim: "Based on 2025 market rates, a custom client portal typically costs between $20,000–$50,000 in initial development, with annual maintenance costs of $10,000–$25,000."
Agency Handy, verbatim: "Custom client portals typically cost $25,000–$60,000 when you factor in development, tools, and ongoing maintenance... takes, on average, 6–12 months to build."
Real case: an agency spent $80K building two custom dashboards over 8 months before abandoning them.
Source: SPP (2025); Agency Handy.
Confidence: Single-source each, consistent across sources.
Caveat: Both sources sell client-portal SaaS — build-vs-buy vendor incentive is real. See R6 — Flag the vendor incentive on every cost claim — AWS price-cut count, SaaS build-vs-buy ranges, agency portal estimates.
Why this matters for Candid: The most-cited figures in any "what does a portal really cost" client conversation. Pair with Pendo 2019 Feature Adoption Report: 80% of software-product features rarely or never used (615 subscriptions analyzed) for the adoption-reality counterweight.
