Chasing eats your evenings
Checking who has paid, working out what's overdue and writing reminder after reminder is slow work that keeps getting pushed to "later".
Singapore-based · For small businesses
Get paid faster, without the awkward chasing.
Polite invoice reminders go out on time, from your own email address, in your own words, with a one-tap WhatsApp draft for each. We set it up and look after it, so you can get back to running your business.
- Nothing goes out until you've approved the wording
- Works with your current invoice list. No new software to learn
- Monthly plan, cancel anytime
The problem
You did the work. Now you're chasing the money.
It feels awkward
Nobody wants to nag a good customer. So reminders go out late, or not at all, and "30 days" quietly turns into 60.
Cash flow takes the hit
Late payments mean you cover salaries, rent and suppliers out of your own pocket while money you've earned sits with someone else.
How it works
Your reminders, running on autopilot
Each customer gets each reminder only once. As soon as an invoice is marked paid, reminders for it stop.
-
01
It starts with the invoice list you already keep
A simple spreadsheet or an export from your accounting software. No new system for your team. Every morning the system checks which invoices need a nudge.
-
02
Reminders go out on a set schedule
Friendly first, firmer later. Stages and timing can be adjusted to suit your payment terms.
-
03
Email from you, plus a one-tap WhatsApp draft
Emails go out from your own business address, so replies come straight to you. For each reminder you also get a ready-made WhatsApp message: one tap to open, you press send.
-
04
A monthly report shows where your money is
What was collected, what's still outstanding by age, your top late payers and who needs a personal call. You also get a short weekly list of who still owes you.
Getting started takes 1–3 weeks

FAQ
Questions owners ask
What about my customers' data and the PDPA?
Your customers' names, emails and phone numbers are personal data under Singapore's Personal Data Protection Act (PDPA). We handle them like this:
- Written consent first. Before any real data is loaded, and again before sending is switched on, you confirm in writing.
- You own the data. We use it only to send your payment reminders and summaries. We don't use it for marketing or share it with anyone.
- Minimal data. We only need invoice number, customer name, email/phone, amount and dates.
- Deleted when you leave. If you cancel, we hand back or delete your data.
You remain responsible for being allowed to contact your customers about money they owe you (for example, an existing business relationship). Reminders are about the invoice only, never marketing. We're not lawyers, so if you're unsure, check the PDPC's guidance or ask your adviser.
Do reminders come from you or from my business?
From your business. Emails go out from your own email account (ideally a dedicated address like accounts@yourcompany) using a separate app password that you can cancel at any time. Customers reply to you directly. We never message your customers in our own name.
Does it send WhatsApp messages automatically?
No, and we'd rather say so upfront. For each reminder we prepare the WhatsApp message and a one-tap link. You (or your staff) open it and press send. Fully automatic WhatsApp needs the official WhatsApp Business API, which comes with extra cost and approval steps. If enough clients want it, we may offer it later.
What happens when a customer pays?
You mark the invoice as paid in the shared invoice list, or just message us and we'll update it. Reminders for that invoice stop. The system doesn't read your bank account, so keeping "paid" up to date is the one thing we need from you.
Won't this annoy my customers?
Each customer gets at most four short, polite messages per invoice, in wording you've approved. At 30 days overdue the system stops and flags the invoice for you to handle personally, because that's when a call works better than another email.
I already use accounting software. Do I need to change anything?
No. We work from your invoice list, either a shared spreadsheet or an export from your accounting software. Some accounting software has built-in reminders. If yours already works well for you, we'll tell you on the call.
Can I cancel anytime?
Yes. It's a month-to-month plan with no lock-in contract. Tell us before your next billing date and we'll stop the reminders, disconnect from your email and hand back or delete your data. The setup fee covers work already done and isn't refundable once you've gone live.
How long does setup take?
Usually 1–3 weeks from the first call, most of which is the test run where you check the messages. How fast it goes mainly depends on how quickly we can get your invoice list and email access sorted.
