You already know who owes you. Your spreadsheet doesn't.
FrostLedger is a purpose-built invoice tracker for minute-writing, corporate secretarial and small service firms. Open it, log an invoice, and it tells you what's outstanding, what's late, and which clients quietly take 60 days to pay.

Chasing money is a second job you never applied for
Small firms rarely lose invoices. They lose track of them — which is the same thing three weeks later when the money hasn't arrived and nobody remembers who was supposed to follow up.
The invisible overdue pile
A spreadsheet shows dates. It doesn't shout when one passes. Invoices go late quietly, and you find out when the bank balance does.
The month-end reconstruction
Re-sorting, re-summing, fixing a total that broke because someone typed 12,500 into a text cell. Same ritual, every month, forever.
Billing through an intermediary
You invoice one entity but the work belongs to another. Spreadsheets have one "client" column, so the trail goes cold when someone asks who the job was actually for.
No memory of who pays badly
The client who always pays at 75 days looks exactly like the one who pays at 10 — until you've built a payment history you can actually sort.
tracker_final_v7(2).xlsx
Two people, two copies, one overwrite. Or a cloud subscription that locks your ledger behind a login and a monthly bill.
Accounting software is too much
Full ledgers want a chart of accounts, tax codes and a training day. You wanted to know what's unpaid.
Four things it does that a spreadsheet can't
These are live, looping recordings of the real interface. Nothing here needs a plugin, a login, or a connection.
Log an invoice, and every total updates itself
Invoice number, amount, dates, who you billed, who the work was for, PIC, salesperson, PO and reference — one form, dd/mm/yyyy throughout, MYR by default with 11 other currencies.
Hit save and the six KPI cards, the ageing, the client history and the 12-month chart all move together. There is no formula to drag down.
Nine filters, one search box, instant answers
All, outstanding, overdue, due within 7 days, draft, sent, viewed, partially paid, paid, cancelled — tap one and the list answers immediately.
Search runs across invoice number, client, end client, PIC, salesperson, PO, reference and description. No filter menus, no re-sorting, no lost row.
Late invoices flag themselves
Every invoice carries a live due-date colour: amber inside seven days, red once it passes. Status flips to Overdue on its own — you don't maintain it.
Crystal, the advisor built into FrostLedger, reads your ledger every time you open it and says, in plain language, what needs attention today — the biggest exposure, who has started paying slowly, and what lands this week.
Meridian Advisory holds your largest open balance. Worth confirming their payment run dates.
Rank clients by how they actually pay
The leaderboard sorts your top ten four ways: by amount billed, by average days to pay, by number of invoices, and by a five-star payment rating the app works out from your own paid dates.
Each customer record holds phone, email, director, credit limit, last contact and notes — and warns you when their open balance crosses the limit you set.
The same job, two very different Mondays
Nothing against spreadsheets — FrostLedger exists because one stopped being enough. Here's where the difference actually shows up.
| Task | Spreadsheet or notebook | FrostLedger |
|---|---|---|
| What's outstanding right now | Filter, re-sum, hope no cell is text | On screen the second you open it |
| Spotting overdue invoices | You check, or you don't | Colour and status change on their own |
| Adding an invoice | Insert row, copy formats, drag formulas | One form, everything recalculates |
| Partial payments | A second column, or a note nobody reads | Amount paid tracked; balance shown on the tile |
| Billing an intermediary | One client column, so context is lost | Billed-to and end client kept separately |
| Who pays slowly | Guesswork, or a pivot table you'll build once | Average days to pay and a 5-star rating per client |
| Client details | A second tab, usually out of date | Phone, email, director, notes, credit limit warnings |
| Duplicate invoices | Found eventually, by accident | Invoice numbers stay unique and searchable |
| Month-end picture | Build a chart if you have the hour | 12-month billed vs collected chart, always current |
| Backup | Whichever copy is newest, probably | Auto-saved locally; one-click JSON export |
| Cost & setup | Free but manual, or a monthly cloud bill | Open it and start working. No account, no renewal |
| Learning curve | You already know it — that's the trap | About five minutes, because it only does this |
Built around how service firms actually get paid
Six KPI cards
Outstanding, overdue, paid this month, due this week, billed this year, and average payment time.
Nine status filters
Draft, sent, viewed, partially paid, paid, cancelled — plus outstanding, overdue and due within 7 days.
Search that reaches everything
Invoice number, client, end client, PIC, salesperson, PO number, reference and description.
12-month billing chart
Billed against collected, month by month, with outstanding stacked on top.
Client leaderboard
Top ten by amount, pay time, invoice volume or star rating.
Customer records
Contact details, director, notes, last contact date and a credit limit that warns you when it's breached.
Payment ratings
A five-star score per client, calculated from how fast they've actually paid you.
Crystal, your advisor
Flags what needs chasing the moment you open it: overdue balances, invoices due this week, and clients slipping behind.
Twelve currencies
MYR by default, plus SGD, USD, EUR, GBP, AUD, JPY, CNY, INR, THB, IDR and HKD. Dates in dd/mm/yyyy.
Day and night modes
The same icy interface, warm-lit or midnight. Compact view when the list gets long.
Auto-save and ledger files
Saved to your browser as you type. Save or open a ledger file directly on your computer where supported.
JSON export and import
Your whole ledger in one portable file — the backup, and the way you move between devices.
Your ledger stays yours
FrostLedger was built by a working corporate services practice to run its own billing. That shaped every decision about where the data lives.
- Nothing leaves your machine. No server, no sync, no analytics. The app has nowhere to send anything.
- No account, ever. There's no sign-up, so there's no password to lose and nobody to lock you out.
- Works offline. On a plane, in a client's meeting room, on hotel wifi that doesn't.
- Yours to keep. No licence server to check in with and no remote switch that can turn it off.
- Portable by design. JSON export is a plain readable file, not a proprietary format you'd need this app to open.

Reasonable questions
Where is my data actually stored?
In your own browser, on your own device, saved automatically as you work. You can also save a ledger file directly to a folder on your computer in Chrome and Edge, and export the whole thing as JSON at any time. Nothing is uploaded anywhere.
What happens if I clear my browser data?
The local copy goes with it — which is exactly why JSON export exists. Export after any significant session and keep the file wherever you keep your other business records.
Can I use it on more than one device?
Yes. Export the JSON from one device and import it on the other. It's a deliberate manual step rather than an automatic sync, because automatic sync would mean putting your ledger on somebody's server.
Does it replace my accounting software?
No, and it isn't trying to. FrostLedger tracks invoices and how clients pay them. It doesn't do tax, double entry or statutory reporting — it's the layer most small firms were doing in a spreadsheet.
I already have years of invoices in a spreadsheet.
They can be brought across. Migration is handled as a paid setup service — your existing records are checked, cleaned and loaded so you start with your real history rather than a blank ledger.
Which browsers does it work in?
Chrome, Edge, Firefox and Safari, on desktop and mobile. Saving a ledger file directly to disk needs Chrome or Edge; everywhere else, auto-save plus JSON export covers you.
Open it and log one invoice
That's the whole evaluation. If the dashboard tells you something your spreadsheet wasn't telling you, you have your answer in about two minutes.
