Website design for Delaware, delivered remotely

We take on website work for Delaware businesses remotely from Malvern, PA, and every stage is reviewed in your own browser.

Why it matters: 29,706 business establishments operated in the state in 2023, and 85.9% of them employed fewer than 20 people.

Go deeper: how a remote build runs, stage by stage

Health care and social assistance alone holds 16.8% of the 457,635 paid employees counted in the state in 2023.

Most of a build runs remotely; New Castle County is one of the six counties in our Business Profile, so in-person sessions there are easiest when a project calls for them.

The three cards above are the three largest of the 12 sectors we read for the state, by paid employees: health care and social assistance, retail trade and accommodation and food services.

Finance and insurance is fourth, with 45,586 paid employees in 1,999 establishments.

  1. Health care

    76,784 paid employees across 3,066 establishments in 2023; a site here needs online booking, intake forms and an accessible path for every patient.

  2. Retail

    62,102 paid employees across 3,742 establishments in 2023; a site here needs stock that matches the till and a phone checkout.

  3. Hospitality and food

    46,106 paid employees across 2,444 establishments in 2023; a site here needs hours, menus and bookings that read on a phone in a hurry.

Websites we built

Six live sites we built open here in a preview window, the same way your build is reviewed before launch.

Why it matters: A working site shows how a build loads, reads and takes an enquiry, which no mock-up can.

Go deeper: how the previews work

Preview opens the live site inside a sandboxed frame on this page. Atlas Peptides blocks framing, so its preview is a dated screenshot instead.

None of the six is presented as a Delaware business; each one shows a job a site has to do, whatever the city.

Between them they cover a configurator that prices as you build, online scheduling, booking with reviews pulled in, a shared stock count, a quote form and a checkout.

29,706 businesses, in public numbers

The state had 29,706 business establishments in 2023, +15.3% since 2018, by County Business Patterns.

By the numbers: 1,051,917 people lived in the state in 2024, +8% since 2019, and payrolls counted 457,635 employees.

Go deeper: what County Business Patterns counts

Of the 29,706 establishments, 25,503 had fewer than 20 people and 3,549 employed 20 to 99. Another 576 employed 100 to 499, and 78 employed 500 or more.

Within the 20-to-99 band, 2,650 establishments had 20 to 49 people and 899 had 50 to 99. The average establishment employed 15.4 of the 457,635 paid staff.

County Business Patterns counts employer establishments, locations with paid staff, so a sole owner with no employees is not in the 29,706; that is one establishment for every 35.4 residents.

NAICS 541511, custom computer programming, includes custom web page design and all other custom software, so 257.5 per 10,000 businesses is a ceiling on web-design firms in the state.

Health care leads, with 76,784 employees

Health care and social assistance employed 76,784 people in the state in 2023, the most of the 12 sectors we read.

Why it matters: who a site talks to follows the sector mix, and retail trade comes next at 62,102 employees.

  • Health care: 25 employees per establishment; booking and intake matter most.
  • Retail: 16.6 employees per establishment; stock and checkout must agree.
  • Hospitality and food: 18.9 employees per establishment; hours and menus must read fast.
Go deeper: who these pages are written for

3,066 health care and social assistance establishments in the state need online booking, intake forms and an accessible path for every patient. The 3,742 in retail trade need stock that matches the till and a phone checkout.

Accommodation and food services counts 2,444 establishments that need hours, menus and bookings that read on a phone in a hurry, and finance and insurance, fourth at 45,586 employees, needs secure forms, plain disclosures and a short path to a call.

Professional, scientific and technical services ranks fifth at 39,610 employees, and the 12 sectors we read cover 402,214 of the 457,635 paid employees in the state.

Together the four employ 230,578 people, 50.4% of the payroll count; the sector figures shape the scope, and the six sites above are our delivered work.

765 custom programming firms statewide

765 custom computer programming establishments (NAICS 541511) operated in the state in 2023, +76.7% since 2018.

Yes, but: that code also covers all custom software, so 257.5 per 10,000 businesses is a ceiling on web-design firms, not a count.

  • Graphic design (NAICS 541430): 38 establishments in 2023.
  • Marketing consulting (NAICS 541613): 268 establishments in 2023.
  • Advertising agencies (NAICS 541810): 72 establishments in 2023.
Go deeper: how to compare the firms on your list

With 803 programming and graphic design establishments in the state, ask each firm for live sites you can open, who will own the code and domain, and a written scope.

The wider NAICS 5415 group, computer systems design and related services, counted 1,407 establishments, 473.6 per 10,000 businesses.

Marketing consulting (268) and advertising agencies (72) often sell websites too, so the full field in the state is wider than the programming count.

Custom programming establishments went from 433 in 2018 to 765 in 2023, while graphic design stood at 38, 12.8 per 10,000 businesses.

Those 765 programming firms employed 5,925 people, about 7.7 each. The wider 5415 group employed 11,143.

From 25,771 to 29,706 businesses since 2018

Establishments in the state rose from 25,771 in 2018 to 29,706 in 2023, a change of +15.3%.

The bottom line: information grew the most of the 12 sectors, +82.9% in establishments, while finance and insurance moved −0.4%.

  • 20 to 99 employees: 3,170 establishments in 2018, 3,549 in 2023.
  • 100 to 499 employees: 531 in 2018, 576 in 2023.
  • 500 or more employees: 70 in 2018, 78 in 2023.
Go deeper: what the change means for a website

Information went from 585 to 1,070 establishments between 2018 and 2023; finance and insurance went from 2,008 to 1,999.

Professional, scientific and technical services came second, +41.6%, and educational services third, +30.7%.

That is a net gain of 3,935 establishments: each new one needs a first site, and each established one carries addresses and rankings a rebuild must keep.

Paid employees went from 405,809 to 457,635 over the same years, +12.8%. Population moved +8% from 2019 to 2024, to 1,051,917.

Ranked 60th of 64 places by businesses

The state ranks 60th of the 64 places we build pages for by business establishments, and 2nd for programming firms per 10,000 businesses.

By the numbers: population growth since 2019 ranks 13th of 64, and the share of establishments under 20 staff ranks 17th.

Go deeper: why every place is measured the same way

Every place page uses the same Census tables, so these ranks compare like with like: 29,706 establishments here against the 64 places' own counts, 5th for their change since 2018.

Programming firms run 257.5 per 10,000 businesses here against a median of 85.2. The under-20 share is 85.9% against 84.4%.

The 64 are the places whose web design searches clear 500 a month in Semrush's exact data, state pages counted with any places folded in; this one draws 740, 55th of the 134 places we measured nationwide.

How a Delaware web project runs

A project here runs in the same five stages as every build of ours, from agreeing what the site is for to launch.

What you get: the scope, price and schedule in writing at stage two, before anything is designed or built.

Go deeper: what happens at each stage

Stage one fixes who the site talks to; in the state, where health care and social assistance employs 76,784 people, that answer often sets the integrations.

Stage five hands the site over in your own accounts, a handover any of the 1,407 systems design establishments in the state could pick up from.

For the 3,742 retail trade establishments here, stage two usually lists stock that matches the till and a phone checkout.

The five stages in order; the written scope, price and schedule come at stage two.
  1. Agree what the site is for

    Who the site talks to, what it must get them to do, and what it connects to.

  2. Scope, price and schedule in writing

    Pages, integrations, price and dates on paper before any design starts.

  3. Design in the browser

    Real content at real widths, reviewed on your own phone as it takes shape.

  4. Build and wire it up

    Code, forms, CRM, analytics and accessibility checks, in one pass.

  5. Launch, hand over, stay on

    The site goes live in your accounts, and we stay on for support.

Web design questions from the state

Not answered here? Call the office: (610) 890-9711

Yes. We take on website work for Delaware businesses remotely from Malvern, PA, and every stage is reviewed in your own browser. You deal directly with the people designing and coding the site, and calls are set in Eastern hours, the clock the state's 29,706 establishments keep.

The scope sets the price, not the ZIP code: pages, integrations and what the site must do, for one of the 25,503 small establishments here or a larger one. You get the price and schedule in writing first; advertisers paid about $7.69 a click for the main web design phrasing here (Semrush).

Hire a designer when the site has to book, quote, sell or connect to a CRM; a builder fits a site a standard template can serve. In the state, 85.9% of establishments employ fewer than 20 people, so we say which route fits before quoting anything.

Yes. Titles, headings, page speed and schema go in while the site is built, and Search Console is connected at launch, so the 560 monthly searches (top phrasing 390) in the table above are targeted from day one. “web design delaware” alone draws 390 a month, by Semrush’s count.

Your accountant decides how to book it, under federal and Delaware rules. Our proposals separate design, development, hosting and support, so each line can be booked on its own; 29,706 establishments in the state face the same question, and we do not give tax advice.

Not when every old address is mapped to its new page and redirected before launch, so rankings and links carry over. For any of the 29,706 establishments in the state, that map is the first thing a rebuild of ours produces.

Yes. We build to WCAG 2.1 AA: keyboard paths, contrast, labels and headings checked before launch, with no overlay and no certificate claimed. It matters most for the 3,066 health care and social assistance establishments in the state, whose patients include people of every ability.
