Accounting built for Trinidad and Tobago.
Invoices, bank matching, payroll with NIS, PAYE and health surcharge, and VAT laid out like the BIR form. For businesses, and for the accountants who look after them.

The dates you keep in your head, kept for you.
VIKI Books knows the Trinidad and Tobago calendar. It lists every deadline for your business, soonest first, with your BIR numbers beside each one.
What it does, on the screens you will use.
Tick off the bank statement in one click
Import the statement and VIKI Books has already found the match for each line: the payment, the date, even when the bank is a day behind your books. You check them, then accept them all at once.
- Lines it cannot match: find, create or ignore, one click each
- Bank rules for the charges that repeat every month
- Reconcile to a difference of zero, and undo if you need to

Quote, invoice, paid
Choose the customer and what you sold; the price and VAT fill in themselves. When they say yes, the quote becomes the invoice in one click, with your logo and their payment terms. Record the payment and it is in your bank.
- Send by email or as a WhatsApp message
- Credit notes, customer statements, payment reminders
- Bills and expenses kept apart, because only one of them is a debt

Payroll with NIS, PAYE and health surcharge worked out
Start a pay run for the pay date and every person's deductions are calculated at the rates in force on that date. Add overtime or a bonus, check the draft, post it. Wages and the employer's NIS go into your books in one go.
- Payslips ready to print or send
- Monthly NIS, PAYE and TD4 figures ready to carry over
- TD1 deductions, staff loans and union dues taken off by themselves

VAT return in the BIR layout
When VAT is due, open the return. It is set out box by box, in the same order as the BIR form, so you copy the figures onto e-Tax. Mark it filed and paid, and it comes off your list.
- The TT$600,000 registration check over the last 12 months
- Corporation tax, business levy and green fund levy estimates
- Clearance certificates with their expiry dates

Room tax and service charge for guest houses and restaurants
Switch on hotel accommodation tax and a service charge once. Tick which lines each one goes on, rooms yes, dinner no, and each shows as its own line on the bill. Room tax is kept apart as money owed to the BIR, never counted as sales.
- A monthly report of room tax collected and service charge earned
- Products remember which charges apply to them

For accountants: every client on one page
Each client company has its own books, bank and VAT. You see them all together, with what needs attention. Combined reports put companies side by side with a total, and you decide which of your staff sees which client.
- Review and year-end checks, and requests to your clients
- Data entry access for client staff who should not see the bank or profit

Moving from QuickBooks or a spreadsheet
Export your lists from the old system and import them here, in the order the page shows. VIKI Books reads a QuickBooks export as it comes out. "Check first" shows what would be added and skipped before anything changes.
- Balances and every unpaid invoice and bill come across
- Your old reports are kept as PDFs with the business
- Compare the two trial balances to the cent before you switch

Your data is yours, and it is kept safe.
A full copy every night
Your books are copied automatically every night and kept for 30 days. Each copy is checked after it is made.
Take it with you any time
Download a backup whenever you like, or export everything to one Excel file. You never have to ask us for it.
Each person sees only their part
Every person has their own sign-in. Data entry staff never see your bank, profit, reports or taxes.
Every change is recorded
The audit trail shows who changed what, when, and the value before and after. Nobody can edit or delete it.
Closed months stay closed
Close a month and nothing dated in it can be changed by accident. Reopening it is recorded too.
Guessing a password does not work
Ten wrong passwords and sign-in is held for fifteen minutes. A forgotten password is reset by email.
To be clear: VIKI Books prepares your VAT, PAYE and NIS figures and your deadlines. You, or your accountant, check them and file them with the BIR and NIBTT.
