A contractor website that showcases your track record and turns leads into tenders

A project portfolio with before-and-after photos, service types (renovation, new build, interiors), online quote requests, SBU certification, and client testimonials.

Indonesia's contractor industry is highly fragmented: from large firms handling state-owned enterprise and high-rise projects, to local contractors specializing in home renovations with a crew of 5-10 workers. What separates the winners from those who stay stuck: the ability to present a project portfolio credibly. A client won't hand a IDR 500M-5B project to a contractor that exists only as a WhatsApp account with no digital portfolio. Webiti helps mid-sized contractors, renovation specialists, and home-building services in Madiun, Surabaya, Yogyakarta, and other cities build a website that showcases a professional project portfolio, the certifications that make them credible in the eyes of government and corporate tenders, and a quote-request flow that connects clients directly with the sales team.

// industry context

Reality & opportunity for Contractor websites.

Indonesia's construction industry is estimated at IDR 2,500-3,000 trillion per year, split across: building construction (the largest sector), infrastructure (toll roads, bridges, irrigation), industrial (factories), housing, and specialties (MEP, finishing). The market is divided among the state-owned construction firms (WIKA, Adhi, PP, Hutama, Brantas), large private contractors (Total Bangun Persada, Acset), and thousands of small-to-mid contractors focused on residential and small-to-medium commercial work. The regulations are very strict: Law No. 2/2017 on Construction Services, BUJK (Construction Service Business Entity) certification from the construction services board (LPJK), the SBU (Business Entity Certificate) per work classification (B-construction, M-mechanical, E-electrical, SP-specialist), the SKK (Work Competency Certificate) for experts, and — for government projects — registration on the LKPP procurement system (SPSE) and a construction business license (SIUJK). Since Presidential Regulation No. 12/2021, government tenders have become more transparent via SPSE — contractors without a strong digital presence struggle to qualify. Key trends: private tenders increasingly ask for an official website link to verify; a digital portfolio with photos/drone-shot video becomes a differentiator; and corporate client testimonials with company logos sell strongly. In the Madiun region, there are hundreds of mid-sized contractors and home renovation services with good quality but no digital presence — a big opportunity to capture the middle-class market looking to renovate or build a new home.

// pain point

Specific challenges for Contractor websites.

challenge 01

The project portfolio is scattered across phone galleries

Photos of finished projects sit on a worker's or supervisor's phone. When a new client asks 'have you handled a similar project?', there's no link to share. A website with a structured gallery becomes permanent proof of work.

challenge 02

Chaotic quote requests over WhatsApp

A client chats: 'How much to renovate a 4x5 kitchen?' — the admin replies, the client asks for a breakdown of materials, labor, and profit, and so on. It can take 30+ messages for one quote. An online quote form with structured fields cuts that cycle short.

challenge 03

SBU and SIUJK certifications aren't highlighted

The contractor already holds the BUJK, SBU, and SIUJK, but the certificates just sit in a drawer. When bidding on a tender, the client asks for a verification link. A website with a certifications page (certificate photos + numbers) meets the compliance requirement.

challenge 04

Before-and-after photos aren't curated

A renovation is most persuasive through before-and-after shots, but the 'before' photos are often not taken from the same angle as the finished result. Without a before-and-after gallery, clients can't visualize the transformation.

challenge 05

Corporate client testimonials aren't displayed

The contractor has handled large corporate projects (factories, offices, hospitals, malls) with great testimonials, but that information has no channel. Client logos + official testimonials sell strongly for a new tender.

// features you need

What a Contractor website must have

Project Portfolio with Filters

Filter by: category (residential/commercial/industrial/renovation), location (city/province), year, project value (range category). Each project has a page with multi-angle photos, a description of the work, the duration, and a client testimonial.

Services Page with Specializations

Structured services: building a new home, full renovation, partial renovation (kitchen/bathroom/roof), interior fit-out, MEP, AC ducting, and more. Each service has an indicative price range and an FAQ.

Structured Quote Request Form

Fields: type of work, area size, existing condition (photo upload), preferred material specs, target timeline, budget range. The engineering team can quote more accurately with complete information.

Certifications and Legal Page

SBU, SIUJK, BUJK, ISO certificate if any, and SKK for experts (certified civil engineers). Certificate photos + numbers for verification. Required to qualify for government and corporate tenders.

Before-After Gallery

Specifically for renovations: before and after photos from the same angle, with the work timeline. A visual transformation that is highly persuasive for renovation clients.

Client Testimonials with Logos

The client company's logo (with permission), a written testimonial from the project manager/director, the project value, and a case-study link. Trust badges for a new tender.

// why a website matters

Why a Contractor website becomes a priority

Because choosing a contractor is a high-trust decision: the client commits to a project worth tens to hundreds of millions that will run for 3-12 months with plenty of risk. A client won't pick a contractor on a neighbor's recommendation without independent verification. They search, check the portfolio, read reviews, and verify certifications. Without a website showing the track record, certifications, and testimonials, your contractor is seen as a 'handyman' even if you're capable of corporate projects. With a seriously designed website, even a mid-sized contractor can position itself on par with a large firm and win tenders that were previously out of reach. Beyond trust, a contractor website is lead generation for tenders. Many private and corporate clients today search 'office renovation contractor Surabaya' or 'home building service Madiun' before requesting a quote. The contractor that appears at the top of search results gets high-quality, pre-qualified leads (they've already seen the portfolio and are interested). What's often overlooked is that a contractor website is also a compliance tool for government tenders. The LKPP procurement system grows ever stricter in demanding transparency, and a contractor with a website showing complete certifications scores better in the LKPP rating system. Webiti designs contractor websites with a professional tone, photo-first design with project drone shots, and a structure that makes certification verification easy.

// case study

CV Karya Bangun Sentosa, Madiun — A Digital Portfolio Delivered Its First Corporate Tender

CV Karya Bangun Sentosa, a mid-sized contractor in Madiun skilled at renovating homes and shophouses, struggled to move up to corporate projects because it had no provable portfolio — all the project photos sat on a supervisor's phone. Every quote request took dozens of WhatsApp messages. We built a website with a filterable project portfolio, a before-and-after renovation gallery, a structured services page, a quote-request form with complete fields, and a certifications page displaying the SBU, SIUJK, and BUJK for tender verification.

outcome

Won its first corporate office renovation tender six months after launch, the incoming quote requests were far more complete so the engineering team could prepare quotes 3x faster, and clients began listing the website link as a verification requirement

// client testimonial

Our quality of work is honestly no less than the big contractors', but without a portfolio to show, we were always treated as 'handymen.' Once we had a website with project photos and full certificates, tender committees started taking us seriously. We won our first corporate office tender precisely because they could verify our track record online. The quote form also means my team is no longer drowning in WhatsApp chats.

Common questions about Contractor websites

How do I display project photos without violating client privacy?

Client consent before uploading photos is mandatory. For corporate projects, the owner usually agrees because it's positive exposure for them too. For private homes: get the owner's written consent, and blur sensitive details (address, license plates).

Will the website be friendly to SPSE LKPP tenders?

Yes. We structure the certification info (BUJK, SBU, SIUJK), project experience (per LKPP classification), and expert personnel so an LKPP compliance officer or tender committee can verify it easily. The file format is ready to attach to tender documents.

Can quotes be generated automatically from the form?

For rough quotes (an IDR/m² range), yes. For accurate quotes with a detailed bill of quantities (BOQ), a site visit and engineering review are still needed. The online form cuts the early stage short: filtering serious leads from people who are just asking around.

What about individual contractors without a BUJK?

You can still use a website, but with positioning as a 'renovation service' or 'skilled handyman service' rather than a 'contractor' (which implies a BUJK). The B2C market (private homes) doesn't require a BUJK as strictly as large government/corporate tenders.

How much does it cost to build?

The Company Profile package at IDR 499k suits a small-to-mid contractor with a basic portfolio and a quote form. The Profile + Blog package at IDR 799k for a contractor with multiple services, a before-and-after gallery, and a complete certifications page.

Is there SEO for 'home renovation service Madiun'?

Yes. We prioritize local SEO with service + location keywords. A page per service + per location (home renovation Madiun, home building Magetan, etc.) to capture specific searches.
