Add a project code to every contract, and keep milestones, site materials, and overdue payments in one place.

One-month free trial before you buy.

Sound familiar?

  • Progress billing is tracked in a spreadsheet only one person understands
  • Materials are bought centrally and used on sites, but never checked against each other
  • A client's 90-day payment term quietly becomes 150 days
  • When you need to act on a late payment, the records are scattered everywhere

What changes with Flows

The money side of every project, organized:

Phase billing in spreadsheets
A payment plan whose periods match the project's milestones
Materials lost between warehouse and site
A warehouse per site, with transfers and stock cards
Late payments followed up from memory
A collections timeline with penalty interest
Project codes only in file names
Custom fields on contracts — searchable and exportable

Why Flows

What makes Flows different

Not another generic ERP — a system built around how Thai SMEs actually buy, sell, and collect.

Frequently asked questions

Can Flows handle progress billing?

You can set the project's phases as the contract's payment plan, each with its amount and expected date. When a phase is finished, issue its invoice from the contract and write it off once the client pays.

How does Flows help our team communicate?

On any contract or customer, you can @ a colleague and they get a notification, for example to follow up a payment or check materials on site. The whole conversation stays on one screen, so everyone sees the latest updates.

Can we track materials per construction site?

You can set up each site as a warehouse and transfer materials to it from your main warehouse. You'll then see what is at each site and each item's stock card.

How can Flows help when a client pays slowly?

The collections module marks overdue periods automatically and records every call and promise on a timeline. Letters and other documents are kept on file, and penalty interest is calculated daily if your contract includes it.

Keep your projects' payments and materials in one system.
