Our story
Started with the businesses around us.
Our first clients were local service businesses: junk removal, hauling and landscape supply. Most had a website that didn't bring in calls, and follow-up that depended on someone remembering to do it.
We kept the work simple. Build a fast website, get the business found on Google, and automate the repeat parts of the day, like call-backs, quote follow-ups and reminders.
Today we have delivered work in 10 industries, including junk removal, material hauling, landscape supply, tire shops, auto repair, construction, a yoga studio, equipment rental and a nonprofit. Two businesses also run their counters on Inerica POS, our point-of-sale system.
Based in Berkeley, CA. We work with businesses across the Bay Area, and with one in Sacramento.

Meet the founder
Hi, I'm Pankaj.
I started Inerica Systems after watching good local businesses lose jobs for ordinary reasons: the website didn't show up in search, a missed call never got a call back, or a quote sat in an inbox for a week.
I'm a developer, and the company is based in Berkeley, CA. We build the website, the search setup and the automation behind it, quote it before we start, and hand over the code so you own it.
“You should know the price before we start, and own what we build when we finish.”
What we stand for
How we treat your money and your time.
Four rules we hold to on every job, and that you can hold us to.
You see the work
You get every deliverable, a monthly report on what we did, and an invoice that matches the quote.
No lock-in
You own the code, the data and the hosting. If you stop the monthly plan, the site keeps running.
Plain answers
If something won't help your business, we say so before you pay for it, and we put the price in writing first.
A schedule with dates
Most websites launch in about two weeks; we work to a 14-day target. Larger builds get a dated schedule before work starts.
What we do
One team for the whole job.
The website, the marketing, the automation and the AI are built by the same people, so there is one number to call when something needs changing.

What our clients say.
Three clients, quoted word for word. Each quote links to the case study of the build it is about.
“Inerica built our website and handles our marketing. We went from zero Google visibility to getting daily calls within the first month. Best investment we made.”
“They redesigned our site, set up our marketing, and built automations that handle lead follow-up for us. We stopped losing jobs to slow response time. Worth every penny.”
“We work with hundreds of contractors across the Bay Area. Inerica redesigned our site for the contractor experience and now qualified buyers find us easily.”
Questions
Before you get in touch
Straight answers about who we are and how we work.
Who is Inerica Systems?
A small team led by founder Pankaj Tyagi, a developer. We build websites, run local search, set up automation and write custom software for Bay Area businesses. We have built 10 sites so far, and 6 are live on the clients' own domains.
Where are you based, and where do you work?
The company is based in Berkeley, CA. We work with businesses across the Bay Area, including Berkeley, Oakland, San Francisco, Richmond, Albany, El Cerrito and Vallejo, and with one in Sacramento.
How does a project run?
It starts with a free 30-minute call. We then send a written plan and a fixed quote, and nothing starts until you agree to it. Work ships in weekly pieces you can open in a browser. Most websites go live in about 14 days; larger builds get a dated schedule before work starts. A person replies to every message within one business day.
Who owns the code when you're done?
You do. You own the code, the data and the hosting, and on handover you get the source, the database and the deployment notes. If you stop the monthly plan, the site keeps running.
What does it cost?
Builds start at $1,500. Every job is quoted in writing before work starts, so the invoice matches the quote. The full price ladder is on the pricing page.
Do you use AI on client work?
Where it helps. Erica, our assistant, drafts, sorts and answers routine questions inside a client's workflow, and a person approves anything that matters. Erica says it is software wherever it speaks.
