P&L & Invoicing

Minutes a month.
Accounting done.

Upload a month of receipts in one go. They are read, categorised, GST split and posted into your profit and loss, and your balance sheet follows. You type nothing.

Built for small businesses in Singapore. Part of Pro 365, with every other app.kevinchia.sg module.1

Drag a whole month in at once. You do not type a single figure.

Upload them.
Everything else happens.

01

Upload them

Drop the whole month onto the page at once from your computer, or forward a photo to the Telegram bot from your phone. A crumpled thermal receipt is fine.

02

It reads the whole thing

Shop, date, total, every line item, the currency, and whether there is GST on it, including IRAS simplified tax invoices with no separate GST line.

03

It files itself

Into your own category list, with GST split out and the tax code stamped. The shop is remembered, so next month it already knows.

04

Everything downstream updates

Your P&L, your GST F5 boxes and your corporate tax computation. No second entry anywhere.

The GST is split, not just noted. S$86 becomes S$78.90 of expense and S$7.10 of claimable input tax, with the IRAS tax code stamped on it. That is what makes the F5 boxes add up at the end of the quarter without a classifying session.

The shop becomes a supplier. It lands in Contacts on its own, so the address book fills itself as you work. Supplier records never count toward your contact limit. Charging you for scanning receipts would be a strange way to encourage it.

And it remembers. Confirm once that this shop belongs in that category and it will lean that way next time. Nothing is ever learnt silently. You are asked before a rule is written, and you can delete any rule.

How we compare

app.kevinchia.sg P&L vs Xero

Xero is a proper accounting package, built for a business that has a bookkeeper. This is built for the person who is the bookkeeper, and the salesperson, and the one doing the deliveries. Both are honest tools. They are aimed at different people.

This is not the end
of this module.

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 module and lands in every account, usually by the next working day.

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.”

It does not stop at accounting

The rest of your back office is on the same system.

Your P&L is where everything else lands. A confirmed booking, a shop order, a paid invoice, a payroll run and an approved staff claim all post themselves here, in the right month and the right category, without you entering anything twice.

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

That is what a large company pays six figures for and calls an ERP. Pro 365 is every module for S$365 a year, or S$49 a month, plus every module we build after you subscribe.

Questions

Frequently asked.

How much does it cost?

It is part of Pro 365: S$49 a month, or S$365 a year paid yearly, which works out about S$30 a month. That covers the full P&L, invoicing, GST F5 and Form C-S, every other app.kevinchia.sg module, and every module we build later. Email us and we set your business up ourselves.

Can I really upload a whole month at once?

Yes. Drop the lot onto the upload page and they are read one after another, each one categorised, GST split and posted. You can also forward photos to the Telegram bot through the month and never sit down to a batch at all. Whichever way they arrive, the scan count is the same.

What if the scan gets something wrong?

You correct it, and it is a normal editable transaction from then on. If you correct the same shop twice you are asked whether to remember it, and after that the scanner leans that way. Nothing is ever learnt silently, and you can delete any rule it has picked up.

Does it handle GST properly?

Yes, and it stays completely out of the way until you are registered. From your registration date onward, sales are split at 9% and stamped as standard-rated, purchases with GST are stamped as claimable input tax, and the F5 page computes every box from your real transactions. You can flip individual lines to zero-rated, blocked input or import GST where they belong, and the quarter is anchored to your own IRAS filing cycle rather than the calendar.

How many invoices can I send?

As many as you like, with no monthly cap and everything included: your branding, the PayNow QR, sending by email or WhatsApp, reminders and quotes. They are proper tax invoices with your numbering and your GST number, and a paid invoice posts the money into your P&L on its own.

Do I still need an accountant?

For anything that needs professional judgement or a signature, yes. This is not advice and it does not file anything for you. What it changes is what you hand over: categorised, GST split, currency converted and exportable to CSV. Most people find the bill goes down because the typing is already done.

What about my existing numbers?

Leave them where they are. Start from this month. There is no cut-off date and nothing has to be imported before the product works. Scan an older receipt any time you like, or never.

I already pay for the P&L on its own. Does that change?

No. If you are already paying for a single module, you keep your plan and your price.

I buy in US dollars. Does that work?

Yes. Ten currencies are recognised and converted to SGD on the transaction, so your P&L is always in one currency while the original amount stays on the record.

Stop finding out in March.

Upload this month’s receipts and you have a P&L. Email us and we set your business up ourselves.

  1. Pro 365 is S$49 a month, or S$365 a year paid yearly (about S$30 a month). It includes every app.kevinchia.sg module, this one included, with the limits lifted and unlimited invoices, and every module built after you subscribe. Fair-use limits apply to receipt scanning.
  2. GST is 9% and applies only from the registration date you record on your own account. Until then no GST is split anywhere in the product. Figures are computed from the transactions you have entered; app.kevinchia.sg does not file anything with IRAS on your behalf. Figures shown in the screens on this page are illustrative.
  3. Corporate tax figures are a computation from your own P&L and the adjustments you enter, using the published start-up and partial exemption tiers. This is not tax or accounting advice and it is not a filing service.
  4. Ten currencies are recognised and converted to SGD at the point the transaction is recorded; the original amount and currency stay on the record.
  5. Competitor prices are not stated on this site because they are not ours to keep current. The link goes to their own published pricing page. Comparison correct to the best of our knowledge at the time of writing; if a row here is wrong, tell us at hello@kevinchiahd.com and it will be corrected.
  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.
