Illustrative example. Tarsier proposes the entry as a card, and nothing posts until someone with the right access approves it.
Built for businesses that have outgrown spreadsheets and bolt-on apps: multi-branch groups, distributors and retailers, lenders and cooperatives, property owners, rental and service companies, staffing firms, and the accountants who keep their books.
Start from what a business needs
Feature lists are long. What a business actually needs is shorter. We designed TarsierLens around these seven needs and checked every module against them.
“Is this figure right, and can I prove it?”
Every invoice, receipt, payroll run and stock movement posts to one general ledger. Unbalanced, mis-coded or out-of-period entries are refused at posting and flagged on drafts, so month-end isn't when you find them.
“Why am I keying in what's already on paper?”
Forward bills to your company's own inbox, connect bank feeds, drop in a statement or a scan. Tarsier reads them and drafts the documents, and your team reviews and approves.
“Where did that money go?”
Ask in plain words, search everything from one box, follow any document to its journal and back, and trace cash from its source to where it was spent.
“What's due, and is it ready?”
A compliance calendar knows each tax and statutory due date, including holidays, authority extensions and your own. Government forms are prepared from the same ledger.
“Would we pass an audit or a regulator's visit tomorrow?”
Every change to every record is kept in an audit history that can't be edited. Tax and statutory forms are prepared from the same ledger as your accounts, and a copy of each form is kept exactly as it was prepared. Large cash transactions are gathered across branches into a watchlist for AML review. Personal data is encrypted, consent is recorded, and access is limited field by field, as privacy law expects.
“Who can see salaries, and who can approve?”
Access is granted per screen and per action, and the server checks it on every request. Personal names are encrypted and masked for anyone without the grant, including on printed forms.
“Will it still fit in five years?”
Add modules as the business adds lines. Run several companies and branches, trade in any currency, and keep your full history as you grow.
Ask it
Tarsier is built into TarsierLens. It reads the same records you do, has only the access you have, and shows where every answer came from.
Works for the person at the keyboard, with exactly that person's access. It answers questions and drafts work for you to approve.
Works for the company on a schedule or when something happens. For example, it sorts forwarded email and checks clearing accounts overnight. It prepares work for review. It posts only what a standing rule you wrote covers exactly, and records your name as the approver.
Already use an AI agent? It can connect on behalf of a named person and is limited to what both that person and the agent are allowed to do.
You set the rules
Most bookkeeping is the same exact match, day after day. Write a standing rule for that class of entry and Tarsier posts it under your name. Everything else still comes to you.

Illustrative. You choose the conditions, limits and expiry.
Illustrative trace. Any document opens onto everything it's connected to.
See it
Auditors and owners ask the same questions: what is this, where did it come from, and who changed it? TarsierLens answers each one with a click.
Know it
If an error can be caught when an entry is posted, it is caught then. Drafts show warnings early. Period-close checks are the last line of defence, not the first.
Each clearing account is checked against zero. Anything left open names the document and the missing half, and its owner gets a morning summary.
Bring in statements from a live bank feed, a CSV or a PDF read by Tarsier. Lines are matched to the book, bank-only items are booked, and the session is tied out and approved.
Documents move from draft to approved to posted, and corrections are reversals rather than overwrites. Every approval names the person who gave it.
Each module sets its own numbering, with monthly or yearly reset. Numbers have no dashes, so a partial number still finds the document.
A separate test environment runs beside live and can't contact anyone: outbound email, messages and payments are switched off there.
Modules
Start with what you need today and switch on more later. Every module posts to the same books, uses the same permissions and is covered by the same audit trail.
Currency handling goes beyond a single exchange-rate field. Each document line carries its currency and the rate as quoted, and settlements post their exchange gains and losses. Revaluation reports any balance it skipped. Yen are kept in whole units and dinars in thousandths, so no precision is added or lost.
Run a group from one sign-in. Each company keeps its own books, number series, locale and tax currency, and each user works in the company and branch they choose. Reports can cover one branch or all of them.
Trust & security
Attachments are stored encrypted with keys held in a cloud key-management service, separate from the database.
Access is checked by the service on every request, not by hiding buttons. When access is removed, it takes effect on the next request.
Change history is append-only. Telemetry and secrets are excluded only by an explicit, documented policy.
Tarsier has the same access as the person it works for. Its queries are read-only, and its analysis runs in a throwaway sandbox. Anything it writes is a proposal for someone to approve, unless it falls under a standing rule a person set, with limits and an expiry.
TarsierLens runs on a distributed SQL database designed to keep working through hardware failures.
Personal data
Customers, borrowers, tenants and employees trust you with their details. TarsierLens treats each personal field as protected data with its own key to read it, not as one "sensitive" switch.
One customer, two viewers · example
| Field | Collections officer | Teller |

Illustrative. Each person sees what their own grants allow, on screen, in exports and on printouts.
Moving in
Changing systems shouldn't mean starting from a blank page. We work with you to bring your data across, whether it lives in another system or in spreadsheets, and check the numbers with you before you switch.
We go through what you keep today and agree together what moves across: accounts, customers and suppliers, staff, opening balances and open items.
Your chart of accounts, customer and supplier lists, staff pay and bank statements upload from CSV or Excel files, or hand Tarsier the file in chat. Where your data doesn't fit a ready-made upload, we work it through with you.
We compare balances and open items against your old records together, and your team tries it in a test environment loaded with your own data. That environment can't email or pay anyone.
You go live on a date you choose, starting from the opening balances you signed off.
Pricing
TarsierLens is billed monthly, based on the modules and companies you use. Add a module when the business needs it, and stop paying for one you no longer use.
Questions
No. Lending is one module among many. TarsierLens covers accounting, purchasing, sales, inventory, assets, property, rental, subscriptions, HR, payroll and tax, all on one ledger.
Only where you have said it may. By default, Tarsier drafts documents as cards and a person with the right access approves each one. To let routine work flow through on its own, you write a standing approval rule:
A rule can only be created by someone who holds the posting permission themselves, and it can't do more than its author can. Tarsier can't create one. If the author loses the permission, the rule pauses.
No. Tarsier works with your access and no more. Protected fields such as personal names stay masked for it just as they do for you.
The Philippines and Ireland today. The compliance calendar is built to hold more than one country, each with its own rules, holidays and extensions.
Yes, and we do it with you. Charts of accounts, customer and supplier lists, staff pay and bank statements upload from CSV or Excel files, and opening balances carry your position across. For anything else your business depends on, tell us what you have and we'll work out how to bring it in.
Yes. Start with the settings: numbering, approval steps, standing rules, reports, permissions. If something you need isn't there yet, tell us. We work through it with you, try it on your own data, and when it's built it reaches every customer.
Bank feeds can pull transactions automatically through supported providers. Any bank's statements can also be imported from CSV or PDF.
Partner with us
A tarsier's ears are almost as big as its eyes, and we try to live up to that. TarsierLens grew out of the daily work of a real business, and it keeps growing the same way: from the problems our customers bring us. Tell us what slows you down and we'll work through it with you.
Before we show you a screen, we sit with the people who do the work, at the counter, in accounts and in the warehouse. We learn where the time goes, what gets keyed in twice, and which report you rebuild by hand every month.
Much of what you need is a setting: numbering, approvals, standing rules, report layouts, who sees what. What isn't a setting yet, we design with you, test against your own data, and refine until it fits how you work.
When something you raised is built, you hear it from us, not from a release note. And because there is one system, an improvement made for one customer reaches every customer.
Things we hear, and want to hear more of
Tell us how your business runs and where it hurts. We'll walk you through TarsierLens with data shaped like yours, and work with you on what it still needs.
