Your books, kept up to date by your bank account.
Arubis is accounting software from Olympus. Transactions arrive from your accounts, Athena suggests where each one belongs, and your VAT return and financial statements are ready when you need them.
Premium is free until 1 December 2026. No card needed to start.
Good morning
Illustrative interface.
Everything a set of books needs.
Proper double-entry accounting, connected to where your money actually moves.
A real general ledger
Every invoice, bill, payment and bank line posts balanced journal entries to your chart of accounts. Nothing is a spreadsheet underneath.
Bank feeds and statements
Olympus accounts sync on their own. Statements from any other bank import from CSV or Excel.
Invoices, quotes and bills
Quotes customers accept online, invoices with payment links, and bills that go through approval before they are paid.
Botswana VAT
VAT returns under the VAT Act 2026, transfer duty and withholding tax, on invoice or cash basis.
Reports you can trace
Profit and loss, balance sheet and cash flow, with every figure opening to the transactions behind it.
Athena
Ask about your numbers in plain language. Athena reads receipts and proposes entries you approve.
Bank lines arrive. Most of them sort themselves.
Each bank line is matched to an open invoice or bill, caught by a rule, or given a suggested account by Athena. You confirm in bulk and keep moving. When you edit a suggestion, Arubis learns the rule for next time.
- Olympus accounts sync automatically; other banks by statement upload with column mapping
- Match one payment to several invoices, or several lines to one bill
- Reconcile to the statement balance, with a reconciliation report you can reopen

Invoices that collect. Bills that wait for approval.
Send a quote, let the customer accept it online and turn it into an invoice. Invoices can carry an Olympus payment link, so a paid invoice closes without anyone matching it. On the other side, bills need an approver who is not the person who entered them, and a payment run pays several at once.
- Recurring invoices, credit notes and automatic overdue reminders
- Receipts and supplier bills read by Athena and booked for you
- Duplicate bills held before anyone pays them twice

Intelligence that does the routine work, and asks first.
Athena answers questions about your books from the ledger itself, reads the receipts and bills you upload, and suggests rules, matches and entries. Autopilot runs every 15 minutes to match payments and hold duplicates. Anything that changes your books is a proposal until you approve it.
- Questions answered from your own ledger, with the figures shown
- Receipt and bill reading, VAT included
- Proposals you approve or dismiss, never silent changes
- Compared September with August Profit and loss

Built for Botswana tax from the start.
Tax codes carry effective dates, so a rate change applies from the day the law says and older periods stay as they were filed. The VAT return for any period is worked out from the ledger, with each box opening to the transactions behind it.
- VAT Act 2026 returns, on invoice or cash basis
- Transfer duty and withholding tax codes
- Recoverable and non-recoverable input tax
- Lock dates so a filed period cannot change
