We see the aftermath of bad contractor choices regularly. A client bought a plot, got multiple quotes, chose the lowest, and six months into a 14-month build has a stalled project, quality disputes, and a contractor demanding additional payment for items that were supposedly in the original scope.
This happens because selecting a construction company is not the same as selecting the lowest price for a commodity service. The variables between contractors are substantial: build quality, material substitution practices, project management competence, and what happens when something goes wrong.
Here is what to check.
A portfolio of completed, comparable projects
Not renders. Not projects under construction. Completed villas you can visit or that have verifiable rental history. Ask for addresses. If a contractor has completed five 2-bedroom villas in Canggu and you are building a 4-bedroom in Uluwatu, their track record is related but not directly comparable. Larger projects and different terrain add complexity.
Client references you can actually contact
Ask for three recent clients. Call them. Ask: did the build finish on time, was the final cost close to the quote, how was issue resolution, and would they use the same contractor again? Most contractors can produce one or two happy references. Consistent positive references across multiple projects is the signal you want.
Licensing
A legitimate construction company in Bali should hold a SIUP (business licence) and ideally a construction-specific licence (Sertifikat Badan Usaha). The SIUP at minimum. Contractors without proper business registration have no legal accountability in the Indonesian system. Always check.
A fixed-price contract structure
Day-rate or cost-plus contracts put all the budget risk on you. A fixed-price contract pins the contractor to a total cost for a defined scope. Change the scope and there is a defined variation order process. Do not change the scope arbitrarily and expect the price to stay the same - but baseline costs should be locked.
A milestone-based payment schedule
Do not pay large percentages upfront. Payment should be tied to physical construction milestones: foundations complete, structural framing complete, roof on, walls up, fit-out complete, handover. A typical split might be 20% on signing, 20% at foundations, 20% at roof, 20% at fit-out, and 20% at handover. Contractors who want 50%+ upfront present a risk.
A materials schedule in the contract
Material substitution is how cheap bids become cheap builds. A contractor quotes using specific tiles, joinery, and fittings in the estimate, then substitutes cheaper equivalents during construction. A detailed materials schedule in the contract - with specified brands or grades - closes this gap. If they resist, ask why.
A retention clause
Retention means holding back 5-10% of the total contract value for 3-6 months after handover to cover any defects that appear after you move in. Defects that only show up after the first rain, or after the first season of use. A contractor confident in their work will accept a retention clause. One who is not will push back.
A defined variation order process
You will change your mind about something during the build. A kitchen layout, a window position, an additional outdoor shower. Every change has a cost and should be documented, priced, and approved in writing before work starts on the variation. Projects without a clear variation order process end up with disputed invoices at handover.
Who actually manages the site
Some construction companies are essentially sales operations that subcontract everything. Ask who the site supervisor is, how many active projects they currently manage, and how often the supervisor will be on site. A supervisor managing eight projects simultaneously gives each one proportionally less attention. Three or four is more reasonable.
What happens when there is a problem
Ask directly: what was the biggest construction issue you had in the last 12 months and how did you resolve it? Good contractors have answers. Every build has issues. The measure is how they handle them. Contractors who claim flawless track records either have a short history or are telling you what you want to hear.
Red flags worth knowing
Beyond the ten checks above, these are the situations that consistently precede difficult builds:
- -The quote is 30%+ below all other quotes - find out why before being pleased
- -No completed projects you can actually visit or verify
- -Pressure to sign quickly or to pay large upfront sums before documentation is complete
- -Reluctance to put material specifications in writing
- -Subcontracts everything and has no direct employees
- -Cannot name their project supervisor for your job
- -Based overseas with no on-the-ground Bali presence
The cost of getting it wrong
A bad contractor does not just deliver a worse building - they cost more than a good contractor over the life of the project. The reasons stack up: substandard materials that need replacement sooner, structural defects that require remediation, delays that push back your rental start date, and the management overhead of resolving disputes instead of managing occupancy.
The gap between a suspiciously cheap quote and a fair one usually comes down to one thing: whether the builder actually constructs to the bill of quantities. The BOQ is the agreed schedule of exactly what goes into your villa - the grade of steel, the strength of the concrete, the waterproofing system, the fittings and finishes. A good builder prices to it and builds to it. Cheaper operators win the job on the low number and then quietly swap the specified materials for inferior ones: thinner reinforcing bar, lower-grade concrete, a budget waterproofing membrane, fittings that photograph the same but do not last. You do not see the substitution. You see the consequence two or three years on, as cracks, damp, and failures that cost far more to fix than the saving was ever worth.
So the premium you pay a proven builder is not a markup on the same product. It buys the materials you actually specified, the supervision that catches problems before they are buried in concrete, and the quality control that holds the build to the standard you signed off on. No shortcuts where they do not show.
Paying $200-400/sqm more for a proven contractor on a 200sqm villa is $40K-$80K. Against a total project cost of $300K-$600K and 25+ years of rental income, that is one of the better investments you can make in the project.
