What tech stack does an expert practice need?
Ask the internet what software a new expert practice needs and the answer comes back as a table. Twelve tools, five categories, a monthly total somewhere near $400. Many of those tables are published by a company that sells one of the twelve.
The shorter answer has four items.
A one-person expert practice needs four things:
- a website at an address you own
- email on your own domain
- one way for people to book time with you
- a record of who you are talking to
That is the list. Everything past it has to earn its place against a cost that never appears on the invoice.
The address is the asset, and it belongs in your name
Buy the domain yourself, in your own name, at your own registrar. Cloudflare Registrar sells and renews domains at the price the registry charges, with no markup and no renewal premium. GoDaddy is the one most people already have, and it works.
Whoever builds your site can work through delegate access on your account. The account stays yours. When a working relationship ends, you keep the address and the records. You can point them somewhere new the same afternoon.
Hosting is a smaller question than it looks. A site of 10 or 12 pages, edited a few times a year, runs without a content management system. Hosting for a site like that is free or close to it on any modern platform.
Email on your own domain covers two of the four
Google Workspace Business Starter runs $7 per user each month on annual billing, or $8.40 month to month. Microsoft 365 sits in the same range. Either one gives you email at your own domain, a calendar, documents, file storage, and video calls.
People read the address before they read the message. A five-figure proposal from a free consumer account tells its reader something the sender did not intend.
The suite also carries your calendar, which is where booking time with you starts.
One booking page is usually the whole scheduling problem
A practice that sells one thing needs one booking page. Google Workspace includes appointment booking inside Calendar, with the number of pages set by your plan. If that covers your consultation, scheduling costs you nothing beyond the email subscription you already bought.
Calendly's free plan covers one event type. Standard runs $10 per seat each month on annual billing. It adds unlimited event types, automated reminders, and payment collection. A practice with paid sessions and several appointment types gets that money back quickly.
In August 2026, Calendly added two AI tiers priced $8 per seat per month above the plans below them. The scheduling features did not change. That pattern is now common across the category. A tool bought for one job starts charging for a second you never asked for.
Your client record can start as a spreadsheet
The fourth item is the one people overbuy. Four columns cover it: name, source, date of last contact, and the next thing you owe them.
At 20 or 30 open conversations, a spreadsheet holds that without complaint. The discipline of writing it down is what pays.
A dedicated system earns its place when one of three things happens. A second person needs the same view of the same people. The number of open threads passes the point where you can hold them in your head. Or you have started forecasting revenue and need the pipeline in stages.
The all-in-one platforms sold to solo professionals bundle the client record with proposals, contracts, and invoices. HoneyBook, Dubsado, and 17hats are the ones you will meet first. Their own reviewers describe setup as a project in its own right. One reported being two years in with features still unconfigured. Another, a fractional COO comfortable with software, found the interface hard to navigate. That is worth knowing before you spend a launch month on it.
Every tool costs more than its invoice
Every added tool is a login, a renewal, and a new home for your client information. Next year it is also a decision you make again, when the price moves.
The subscription is the smallest part of that. The attention is the rest. In a practice where one person does the work, attention is the scarce thing.
Useful is not a high enough bar for a new tool. A tool earns its place when it removes something you do every week. Improving something you do twice a year does not clear that bar, however good the demo looked.
The automation layer is where this shows up first. Vendor stack lists nearly always add one, so that a booking creates a record and fires a follow-up. With four tools and a handful of consultations a month, there is little there to automate. The wiring costs more attention to build and repair than the copying it removes.
There is also a quieter cost. Each platform you adopt holds a piece of your client history. Platforms change hands, change prices, and shut down. A decade of client history is easier to carry when it lives in fewer places.
What a thin tech stack will not do
Regulated practices do not get to choose. If you hold client money, your state bar sets the records you keep. It also sets how often you reconcile them, and the rules differ by state. Read your own bar's rule rather than a vendor's summary of it. The summary is written to sell the software underneath.
The same goes for health information. A free consumer email account cannot carry protected health information. A paid suite carries it only after a business associate agreement is signed. The settings then have to match, which is a conversation with counsel rather than a plan comparison.
A thin stack also assumes one person. The day a second person needs the same view, personal systems stop being enough. That is when shared ones start earning their cost.
And no arrangement of software produces demand. The stack keeps the practice running once people are talking to you. Bringing them is a different job.
Pull up your card statement for the last three months and read every recurring charge out loud. For each one, say what it did for a client. The charges that leave you quiet are the ones to cancel this week.
