Construction ERP software for contractors in Bangkok
ERP Infra tracks purchase, stock, labour, machinery and cost on every site, and flags what does not add up the same day. Below is what is being built in Bangkok and where projects there tend to lose money.

On 1 April 2026 the Thai Contractors Association warned of abandoned projects, saying diesel had risen 14.3 baht per litre since early March and rebar at least 4.5 baht per kg, and calling the 1989 K-Factor price adjustment formula used in state contracts dangerously outdated.

The work that dominates
- metro rail lines (Orange, Purple extension)
- public-sector civil works under state procurement
- fixed-price private building contracts
Where Bangkok projects tend to lose money
Litres per hour against each machine’s normal.
The Thai Contractors Association reported a 14.3 baht per litre diesel rise in March 2026, which hits plant and haulage budgets directly.
How it worksBudget, committed and actual, per site, every day.
Fixed-price private contracts and an outdated K-Factor formula leave contractors absorbing rebar and fuel increases.
How it worksEvery quotation ranked on landed cost.
Rebar rose at least 4.5 baht per kg in weeks, so purchase rates need to be tracked against what was priced in the tender.
How it worksFigures in the screens above are sample data.
Terms used on Bangkok sites
The words differ from place to place; the records behind them are the same.
- K-Factor
- The price adjustment formula in Thai state construction contracts that compensates for material and fuel cost changes
- Comptroller-General's Department (CGD)
- The agency that runs state procurement rules and contractor registration
- MRTA
- Mass Rapid Transit Authority of Thailand, the client for the metro lines
- e-GP
- Thailand's electronic government procurement system
State contracts use a K-Factor price adjustment formula created in 1989, which the Thai Contractors Association said in April 2026 often tracks consumer price items rather than fuel and steel.

- Can contractors in Bangkok use ERP Infra?
- Yes. ERP Infra is web-based: office staff use it in a browser and site staff in a phone browser, so it can be used on projects in Bangkok. Demos and onboarding are done online by the Flip Retail team.
- Does ERP Infra have an office in Bangkok?
- No. ERP Infra is made by Flip Retail, based in Jaipur, India. Work with companies in Bangkok is done remotely, starting with a one-month pilot on one project.
- What should a construction company in Bangkok check before choosing an ERP?
- Check that it is organised by project and site, that site staff can use it on a phone, and that it can show the same evening what a site cost and whether material used matched the work done. Then ask for a pilot on one of your own projects before committing.
Let’s put every site on one screen.
Tell us how many projects and sites you run. We will walk you through the system on a call and suggest where a pilot would pay back first.
