Web Development · St. Petersburg, FL

St. Petersburg web development for firms whose clients would rather log in than chase an email.

Professional and business services lead private employment in Pinellas County. Firms in that field may need client portals and internal tools, and our view is that this is where custom development pays for itself, if it does.

An advice business runs on documents and on waiting. A client sends something, wonders if it arrived, and emails to ask. A login that shows what's been received and what's still needed can end a lot of that. We built a law practice a custom intake application, so a prospective client can start their matter at midnight and the firm wakes up to an organized file. We built a finance leadership firm a site that sends each visitor to the right seat before anyone picks up the phone. Those are the kinds of jobs we mean by a custom web application, and they apply to financial and legal firms alike. Security and record-keeping rules are for your own adviser to set.

A homepage test can't see inside a portal, and we have no St. Petersburg sample. Here's what it saw across 1274 homepages in our 31-city sample. Blocking time, when a phone can't respond to a tap, had a median of 277 ms. Browser errors turned up in the logs of 38%. 573 ran WordPress and 355 ran on other or custom platforms, with median speed scores of 62 and 62. We build custom, so we'd love to report a clear win. We can't. 12 of the 343 professional services sites had online booking on the homepage. Choose a platform for what it has to do, and not for the score.

A restaurant or venue has a simpler need: reservations and event dates that hold up on the weekend of the Grand Prix. Web apps begin at $575, depending on complexity, with a fixed price after scoping. API integration ties in the billing or calendar you already use. We also build native iOS and Android apps, from $3,750. The St. Petersburg report has the wider picture. Tell us which question your staff answers most by email, and we'll say whether a tool would answer it better.

What web development has to get right in St. Petersburg

  • A client login that shows what's in and what's still needed.
  • Intake forms that produce an organized file.
  • Your adviser's sign-off on how client records are kept.
  • Connections to the billing and calendar you already use.
  • A browser console with nothing to report at launch. 464 of 1228 sites in our 31-city sample had errors in theirs.

Web Development in St. Petersburg: questions we hear.

Should we buy a portal product or have one built?

Buy, if one fits your work and its fees make sense. We'd tell you so. Custom work earns its cost when your process doesn't fit or the tools won't talk to each other.

Is WordPress good enough for a professional firm?

For a brochure site it can be, and in our 31-city sample its median speed score was no different from custom work in any way we'd lean on. A login with client documents is a different question. We do WordPress work and we'll tell you where it stops making sense.

What does a client portal cost?

Web apps start at $575, depending on complexity, and a full portal costs more than a small tool. We quote a fixed price after scoping. The full price list is published, and a firm here pays what a firm anywhere pays.
