Pro 365

Enter it once.
It shows up
everywhere.

Accounting, GST, payroll, staff, customers, bookings, a shop and compliance, on one system. A single thing that happens in your business ripples through everything it touches.

S$365 a year, or S$49 a month, for every module.1

The booking is the only entry. Everything under it is derived from that one fact, which is why nothing can disagree.

That is what a large company pays six figures for and calls an ERP.

Your first hour.
Nothing to migrate.

01

Answer four questions

Business name, sole trader or Pte Ltd, financial year end, GST registered or not. That is the whole setup.

02

Upload this month’s receipts

They are read, categorised, GST split and posted. Start from today; older ones can be scanned any time, or never.5

03

Turn on what you need

Add staff, open a booking page, put a shop link in your bio. Each is a few minutes, and we walk you through the first ones.

04

It joins itself up

A booking, an order, a paid invoice, a payroll run and a staff claim all post themselves into your accounting, in the right month.

And it works
the other way round.

TotalS$86.00

Nobody re-keys anything. Photograph a supplier receipt and the shop is filed as a supplier, the GST is split out, and the expense lands in the right category. Next month the scanner already knows where that shop belongs.

Every module files people into one address book. Customers from bookings and orders, suppliers from receipts. Which is why a customer record shows what they owe, what they booked and what they have spent without you assembling it.

And the assistant reads all of it. Ask what you actually made last quarter after your own salary, in plain English, and it answers from your real numbers rather than from a generic model.6

How we compare

Pro 365 vs buying
the same tools apart

These are the market rates a Singapore small business would otherwise pay for the same jobs, one subscription at a time. It is not a straw man, and the last two rows go the other way.

What it costs
S$365 a year for everything, or S$49 a month
S$2,700 to S$6,800 a year, and still not joined up3

The other way people solve this is to hire somebody. An admin hire in Singapore is S$2,000 to S$3,000 a month.

Ask the assistantIncluded
What did I actually make last quarter after my own salary?
Net profit for July to September was S$49,130. Your own salary and employer CPF are already inside that, at S$28,800 across the three months.
And how much GST do I owe?
S$5,555.70 for the quarter. Output tax S$11,343.60 less input tax S$5,787.90.

Plain English, answered from your own accounts rather than from the internet.6

This is not the end
of this platform.

Ask for something and it gets built. Every account has a Feedback button that raises a real ticket, read by the person who writes the code. If it would help more than one Singapore business it goes into the platform and lands in every account, usually by the next working day. If it is specific to just you, we say so rather than take your money for it.

Need it to work with a tool you already use? Ask the same way. We check that it can be done and tell you straight. You subscribe, by card or PayNow, we build the connection, and you try it on your own account. If we cannot make it work, you get your money back.

Before you sign up, hello@kevinchiahd.com reaches the same place.

From a customer

“An entry point for a small start-up, without being overwhelming.”

“Looking for an easy way to manage my small business, I came across app.kevinchia.sg. This solution has an entry point for a small start-up, not overwhelming, while having more sophisticated features for future scaled-up operations. Had a chance to speak to the founder Kevin and was greatly encouraged that he listens to his clients, big or small, and is always open to see how he can improve the client experience. app.kevinchia.sg not only provides a solution, but provides the relationship management as if you are a big corporate. Very glad to chance upon this software.”

One price, and it stays one price

Everything we build later is already paid for.

Pro 365 is every module for S$365 a year, and every module built after you subscribe arrives in your account at no extra cost. There is no per-user fee, nothing is skimmed off what your customers pay you, and you can take your data with you whenever you like.

Sale or expense Categorised In the P&L GST worked out Tax computed

Built in Singapore, for Singapore rules: GST at 9%, CPF age bands and PR rates, IR8A, ACRA deadlines, public holidays and PayNow. Not an overseas product with a currency setting.

Questions

Frequently asked.

What happens to the numbers I already have somewhere else?

Nothing has to move. Start from the current month. There is no cut-off date and no import step you have to finish before the product works. Older receipts can be scanned whenever you feel like it, and CRM contacts import from a CSV if you have one. Migration is the reason most people stay stuck on a system they dislike, so we removed it as a requirement.

Is there a per-user charge?

No. One price covers the account, and you can invite your team at no extra cost. Employee logins for the staff portal are unlimited at no extra cost, so every member of staff can have one.

Can I buy just one module?

No. Every module comes as part of Pro 365, because they work as one system. If you already pay for a single module, you keep your plan and your price.

How do I get started?

Email hello@kevinchiahd.com and tell us a little about the business. We onboard every business personally: we set up the account, bring in what you already have and walk you through the first month.

What about restaurants, shops and other industries?

Our industry systems (restaurant, retail, tuition, studio, car workshop and car dealer) include Pro 365 at no extra cost, from S$199 a month for your first location. Membership management for associations includes Pro 365 too, from S$99 a month.

What is the working session with the founder?

One session during your paid year, on your own business: your numbers, your pricing, hiring, how you are running things. It is explicitly not a software walkthrough, and you can use it as a clinic on one part of the business. Book it whenever suits you.

Where does my data live, and who can see it?

In a managed Postgres database on AWS, encrypted at rest and backed up nightly, with row-level security so one account can never read another. Sensitive payroll and customer fields are encrypted individually on top of that. It is never sold and never used to train a model. You can export it, and you can delete it.

I am too small for something like this.

That is exactly who it is for. Paid yearly it is about S$30 a month, less than most businesses pay for one of the tools it replaces, and a one-person business gets its accounting, payroll, bookings and a shop in one place. We run our own company on it, and we are a small, senior team.

Do I need to be a Pte Ltd?

No. Sole proprietors, partnerships and companies all use it, and the setup asks which you are so the right things appear. Compliance is the one part aimed specifically at company directors, because ACRA annual returns and directors’ resolutions only apply to companies.

What if the thing I need is not built?

Ask, and you get a straight answer in a few working days. The bar is whether it would help more than one Singapore business. If it would, it gets built into the platform and lands in every account, including yours at no extra cost. If it is specific to just your business we say so rather than take your money for it.

Can it connect to a tool I already use?

Ask through the Feedback button, or email hello@kevinchiahd.com before you sign up. We check whether it can be done and tell you straight. If it can, you subscribe, by card or PayNow, we build the connection and you try it on your own account. If we cannot make it work, you get your money back.

Stop being the
integration layer.

Four questions and this month’s receipts, and you have a working back office. Email us and we set you up ourselves.

  1. Pro 365 is S$49 a month, cancel any time, or S$365 a year billed yearly. Modules are not sold one by one; businesses already paying for a single module keep their plan and price. Industry systems are S$199 a month for the first location plus S$100 a month for each extra location (S$1,999 and S$999 a year paid yearly), and membership management is S$99 a month or S$999 a year, both with Pro 365 included. Team and staff portal logins are unlimited at no extra cost.
  2. Pro 365 includes every module, every limit lifted, and every module built afterwards at no extra cost. The working session with the founder is one session during your paid year, on your own business rather than a software walkthrough, booked whenever suits you.
  3. Comparison figures are indicative Singapore market rates for the same jobs bought one subscription at a time, at the time of writing, and vary with headcount, plan and transaction volume. They are given as a range for that reason and are not quotations. Competitor prices are not stated on this site because they are not ours to keep current.
  4. Your data is held in a managed Postgres database on AWS, encrypted at rest and backed up nightly, with row-level security so one account can never read another. Sensitive payroll and customer fields are encrypted individually on top of that. It is never sold and never used to train a model, and you can export it to CSV or delete it at any time.
  5. There is no migration step and no cut-off date. Older receipts can be scanned at any time or not at all, and CRM contacts import from a CSV. Figures shown in the screens on this page are illustrative.
  6. The AI assistant is included in Pro 365, subject to a fair-use daily limit. It answers from your own data and does not give tax or accounting advice.
