How much does it cost to build a client portal?

A custom client portal ranges from around $10k with a freelancer to $120k+ with an agency, depending on how many workflows it carries. A no-code add-on is cheaper monthly but you rent it. On the devkyn subscription it runs on a plan matched to the workload, and most portals take four to eight weeks — so you pay for roughly one to two active months, not a lump sum.

How long does it take to build a client portal?

Most custom client portals land in four to eight weeks. A status-and-documents portal is on the faster end; one with billing, messaging, and multi-role teams takes longer. On a subscription you see usable pieces ship every week. See the Client Portal Build for the week-by-week process.

What changes the price of a client portal?

The number of workflows, mostly — documents and status are quick; payments, e-signatures, messaging, and multiple client roles each add weeks. Whether it stands alone or has to slot into your existing app and auth also moves it. On the subscription you reprioritize as real client feedback lands instead of paying a change order.

Is a subscription cheaper than an agency for a portal?

For a single-engineer build, usually — a plan matched to the workload with no contract typically beats a $25k–$120k+ agency lump sum, and you skip the pod overhead. A no-code add-on is cheaper to start but you never own it and hit a wall on custom workflows. If you need a large team in parallel, an agency fits better and we'll say so.

What do I own when the portal is built?

The whole thing — unlike a no-code add-on you rent, the code ships into your repo and your cloud account and it's yours. You own the portal, the deploy pipeline, and the client data, and the same subscription can keep maintaining it after launch or hand it off entirely.

Cost guide - Client Portal Development Cost

A client portal — logins, a dashboard, documents, messages, invoices — is a real software build, not a plugin bolted onto your marketing site. That's why the price swings so widely: a no-code tool and a custom agency build are worlds apart in cost and in what they can do. Here's an honest look at each option, the rough weeks each takes, and what you end up owning.

The honest options, compared

Most custom client portals land in four to eight weeks of senior engineering, depending on how many workflows they carry — a status-and-documents portal is faster than one with billing, messaging, and multi-role teams. No-code is cheapest until it hits a wall; an agency is the priciest lump sum; a subscription sits in the middle with no contract.

Option	Typical cost	Rough timeline	What to know
Custom agency build	$25k–$120k+ fixed bid	2–4 months	A full project team and a lump-sum quote. Capable, but you pay for the overhead and change orders, and the timeline is set by their pipeline.
Freelancer	$10k–$50k, variable	1–3 months	More affordable, but you manage the build and carry the risk of a stalled handoff on something your clients log into every day.
No-code / SaaS add-on	$50–$500+/month	Days to set up	Fast and cheap to start, but you rent it, brand it their way, and hit a ceiling the moment you need custom workflows or real ownership.
devkyn subscription	Variable by plan	Variable by scope	One senior engineer builds a portal you own, week by week. The selected plan is the monthly rate, not the total — most portals run a month or two of active build, and the code ships into your repo.

About that monthly number

The selected monthly plan is the flat subscription the build runs on, not a fixed project total. A four-to-eight-week client portal is roughly one to two active months of subscription — you pay for the weeks it's active, pause between phases, and after launch the same subscription flips to task mode for the steady trickle of new views and fields a live portal generates.

Rough timelines by build type

Cost tracks time on the subscription, so the honest way to estimate is by build. These are the typical ranges for real devkyn builds:

Build	Typical timeline
Client Portal Build	4–8 weeks typical	See the build →
Internal Tools & Admin Platform	5–8 weeks typical	See the build →
Productized Service Platform	5–8 weeks typical	See the build →

What changes the price

How many workflows the portal carries — status and documents is faster than billing, messaging, and multi-role teams.
Whether it needs payments, e-signatures, or integrations with tools you already run.
How many distinct client roles and permission levels there are.
Whether it's a standalone portal or has to slot into an existing app and its auth.
