A BETTER STARTING POINT
Keep the ambition.

Turn supported receipts and bank transactions into organised records—with an explanation of what each entry means.
Bookkeeping tools plannedNo mystery at year-end.
See what’s complete, what’s missing and what needs a closer look before preparing accounts or a return.
Reviewed filing preparation plannedTRY A WORKED EXAMPLE
“I put money in.
Is that income?”
Not if it’s a loan to your company. Explore three everyday examples and see how the books change.
Use an illustrative amount. Nothing is saved or submitted.
Enter an amount from €0.01 to €1,000,000, using at most two decimal places.
Educational examples only. No VAT, tax relief or currency conversion is calculated. The real treatment depends on your documents and circumstances.
EXAMPLE, NOT YOUR BOOKSEUR
A loan adds cash. It doesn’t create profit.
The company receives €500 and owes you €500. Repaying that loan later is not a second expense.
Company bank+€500.00
Owed to founder+€500.00

Keep the evidence
Bank transfer record and a clear record that the money is a loan, not share capital.

Good questions.
Clearer answers.
Start here when the terminology gets in the way. These are general explanations, not a decision about your company’s tax position.
Read Revenue’s record-keeping guideWhat is the difference between bookkeeping and filing?
Bookkeeping records what happened, supported by evidence. Accounts organise those records into financial statements. Tax preparation applies the relevant tax rules; filing sends the required return to the relevant authority. A balanced spreadsheet is not, on its own, a completed tax return.
Do I automatically need an accountant?
Not every small company must appoint an accountant to prepare its books. Audit requirements are a separate question. Directors remain responsible for adequate records and compliant financial statements, even where audit exemption applies. Eligibility must be checked, and complex situations can need qualified advice.
Check CRO audit-exemption guidanceIs money I put into the business a sale?
Not necessarily. A documented founder loan creates an amount the company owes you. Share capital is different again. Neither should automatically be recorded as customer income. Keep the evidence explaining the purpose of the transfer.
Can I ignore tax registration until I make sales?
Don’t assume that having no sales means having no obligations. Registration depends on the company’s activities. Buying services from overseas can create VAT questions, and paying anyone can create employer obligations. Check your actual circumstances with Revenue or an appropriately qualified adviser.
Revenue guidance on services received from abroadAre CRO, Revenue and RBO the same thing?
No. CRO deals with company incorporation and company filings. Revenue deals with tax registration and returns. RBO records beneficial ownership. Completing one does not complete the others, and the company’s own internal records also need to be maintained.
Will Sentinel Books file returns automatically?
Not at this stage. Future filing tools would need validated calculations, supported filing formats, appropriate access and your explicit approval. No return, incorporation or payment can be submitted from this website. We are not claiming Revenue or CRO approval or affiliation.
What should I gather first?
Start with your incorporation and share records, original invoices and receipts, bank statements, details of company costs paid personally, and any registration correspondence. Keep dates and explanations. Don’t mix personal and company spending or invent an opening balance to make a report balance.

IRELAND FIRST. A WIDER AMBITION.
Local rules.
A more accessible world of business.
Our longer-term aim is guided business setup and bookkeeping across more countries, with conversational help. Each country needs its own reviewed sources, supported business types and tested rules—not a one-size-fits-all answer.
Ireland orientation.
General Irish LTD setup guidance, official-source links and simplified bookkeeping examples. No live filing or personalised tax advice.
Conversational help.
A future ChatGPT-connected assistant could explain records, ask for missing facts and cite the rule it relies on. Calculations and submissions would use separate, tested tools and owner approval.
Country by country.
No other country is supported yet. Before adding one, we would verify local requirements, effective dates, filing access, data rights and where professional review is required.
