Service businessesget paid on time

Billing dates, invoices, and unpaid fees in one system, so your team spends time on clients, not on chasing payments.

One-month free trial before you buy.

Sound familiar?

  • Project invoices go out late because nobody tracks the billing dates
  • Monthly fees renew quietly, get billed late, or get missed
  • Service fees stay unpaid while the client says 'next month'
  • It's hard to see which clients bring in the most revenue

What changes with Flows

Billing dates and unpaid fees, kept by the system:

Billing dates in personal calendars
Payment plans that send their own reminders
Monthly fees renewed from memory
A period per month on the contract, invoiced on schedule
Unpaid fees sitting in a spreadsheet
An up-to-date receivables list with collections behind it
No clear view of top clients
Revenue by customer from real data

Why Flows

What makes Flows different

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

    One annual price, every module included. Add users freely within your tier — no feature gates, no seat fees.

  2. Three languages with auto-translation

    Thai, English & Chinese UI — and the data your team enters is translated automatically, so everyone reads the same records.

  3. Your documents, exactly your format

    Send us your invoice and receipt templates; our team configures them into Flows. Every document comes out looking like yours.

  4. We walk you live — and stay

    Five-step onboarding at no extra cost, then quarterly system stability reports. We don't disappear after go-live.

“Flows ERP lets us cost each piece of work properly and shows where the money moves, which makes controlling costs and judging returns much easier.”

Frequently asked questions

Is Flows still a fit if we don't hold stock?

Flows works well without stock, because its core is contracts, payment plans, invoicing, write-offs, collections, and reports. You can simply leave the inventory module unused.

Can Flows bill a monthly fee on schedule?

Yes, you can set up the job as a contract with a payment due every month. Flows reminds you before each due date and generates the invoice from the contract, so you never miss a billing date.

How do we bill by project phase?

Set each project phase as a payment in the contract, with its amount and due date. When a phase is finished, issue its invoice from the contract, and the write-off center shows how much has been paid.

What happens when a client leaves fees unpaid?

Flows marks the contract as overdue, and you can manage it in the collections module, where every follow-up call and promised payment date is recorded. Flows also supports charging late-payment penalties if your contract includes them.

Bill on the day it's due, and know what's unpaid.
