Bills, slips, and questions in one place

You should spend your time on the business, not on a pile of receipts

Because small paperwork tends to pile up right when you're busiest

If you've ever told yourself “I'll do it later” and watched the pile grow — you're not alone.

Digging through your bag for receipts every month-end

Expense proof is scattered across your bag, email, and chats — and you can't tell what's gone missing.

You don't know real profit until the books close

You see the numbers too late — by the time you realize you're in the red, the whole month has passed.

All your time goes into keying in data

Hiring someone to key it in costs money, an accounting firm makes you wait — so in the end the owner does it.

From the first receipt to the file you send your accountant

Paper does the back-office work end-to-end — but everything stays in your sight and control

AI reads your bills automatically

Snap a photo or attach a slip — the system splits income and expenses in seconds, no typing.

Issue substitute documents

No original bill? The system generates a compliant substitute document per accounting standards.

Payment & receipt vouchers, ready to go

All your proof in one place, ready to hand to your accountant or auditor.

A dashboard of your whole business

See money in and out in real time on one screen — no waiting for month-end.

Auto-filed to Drive

Sorted by month and by business automatically, searchable anytime.

Instant sync to Sheets

When the paperwork gets lighter, so does life

Example experiences from business owners of many kinds

I used to sort bills every month-end. Now I just snap a photo into the chat and the rest is done — no more digging through a bag of receipts.

I don't have to chase down my own monthly subscription slips anymore — the system catches them all from email.

Sales from several online channels get summarized in one place — no more opening multiple screens to compare them myself.

I worried about data security at first, but after trying it I feel much more at ease — every entry is checked before it's saved.

Still wondering about something?

Read the common questions, or just talk to our team — no need to have your questions perfectly ready.

Send us your question
Do I have to type in the data, or is sending a photo enough?
Just snap a photo or attach the bill/slip into the chat — the system reads and categorizes it automatically. No bill? Type a short note and it'll record that too.
How secure is our business data?
Every piece of data is encrypted end to end and stored to enterprise-grade security standards. We keep only what's needed to read and categorize your documents.
Is it really free? Do I need a card?
Genuinely free with no credit card. The free plan reads 10 bills automatically per month; upgrade later if you need more, and cancel anytime — no contracts.
What happens if I go over my quota that month?
Quota resets on the 1st of each month. Over it, you can buy extra credits instantly — they never expire — and you can still record entries manually, unlimited, in the meantime.
How many businesses can I manage, and are they kept separate?
Up to 5+ businesses in one account (by plan), with each business's data, documents, and reports kept clearly separate.
What documents can it issue?
Sales side: quotations, invoices, receipts, and tax invoices. Expense side: substitute receipts and payment/receipt vouchers. Download as PDF instantly.
If I cancel, do I lose my data?
No. All files are stored in your own Google Drive from the start — even if you cancel, your files and document history stay intact.
