Accounting for a new LLC in Estonia: a practical 90-day setup plan for documents, deadlines, payroll, VAT, and first management reports.
Days 1-15: define the finance operating system
The first 90 days are not about perfect accounting. They are about removing ambiguity early enough that routine work becomes repeatable. A new company should decide, during its first two weeks, where documents live, who approves expenses, who owns bank access, and how month-end will be closed.
Founders often postpone these decisions because transaction volume is still low. That is exactly when the setup is easiest. Once invoices, employee expenses, and customer contracts are already scattered across email, chat, and personal folders, every later cleanup becomes more expensive.
Start with three basic rules: one archive for source documents, one cut-off date for monthly delivery, and one named owner for each filing. Those rules create more value than additional software in the first month.
Days 16-30: lock the document flow
By the end of the first month, the company should have a stable route for incoming invoices, outgoing invoices, bank statements, receipts, and founder reimbursements. Decide the required file naming, the approval chain, and the point when a document is considered complete.
If you plan to outsource, this is where the relationship is won or lost. A provider can close the month well only when the client's document flow is predictable. Use the same discipline described in the mistakes review and, if relevant, the e-invoice rollout guide.
Do not mix bookkeeping storage with ad hoc founder notes. Source evidence, approvals, and explanations should live together so that month-end review does not depend on memory.
Days 31-60: clarify tax and payroll routines
In the second month, shift attention from setup to compliance rhythm. Confirm whether VAT registration is already required or likely soon, how employee or board payments will be handled, and what data must reach the accountant before filing dates.
If the company will pay salaries or board fees, design payroll cut-offs early. Late timesheets, unapproved bonuses, or missing leave information are common reasons for avoidable TSD errors. The payroll workflow guide helps define these handoffs.
The founder should also know what questions must be escalated instead of booked automatically: cross-border sales, shareholder loans, unusual expenses, or related-party transactions.
Days 61-90: add management reporting before problems scale
By the third month, the company needs more than compliance. Management should receive a short pack showing revenue, cash position, liabilities due, receivables aging, and open exceptions. Even a lean board pack is enough if it arrives on time and highlights what changed.
This is the stage when founders realise whether they want a pure bookkeeping supplier or a more structured finance partner. If reports arrive late or without commentary, decisions will drift into reactive mode.
Pair the reporting pack with one short monthly review. Ask what surprised the team this month, which balances remain open, and what must be fixed before the next close.
The founder dashboard for the first quarter
Keep the first-quarter dashboard practical:
- cash runway and cash due within 30 days;
- documents still missing for the latest close;
- VAT or payroll items awaiting decision;
- customer receivables older than agreed terms;
- any filing or reporting deadline at risk.
This dashboard should fit on one page. The aim is not sophisticated FP&A. The aim is to stop the company from discovering basic process failures too late.
When to involve an external partner
A founder can keep finance coordination in-house for a while, but should bring in outside support once VAT, payroll, international sales, or board reporting become regular. At that point the cost of improvisation often exceeds the cost of structure. See also: cost to register a company in Estonia in 2026.
If you are choosing the model now, compare it against the questions in service vs in-house and pressure-test the expected scope with your pricing benchmark. See also: share capital in Estonia 2026.
The first 90 days should leave the company with a repeatable close, a visible compliance calendar, and management data that arrives while it is still useful. That is the real milestone, not just surviving incorporation paperwork. See also: legal address and contact person in Estonia.
In my experience, accounting for a new llc becomes risky only after responsibilities stay verbal for too long. Write the owner, cut-off, and review step before the busy week starts. See also: company registration timeline in Estonia 2026.
Frequently asked questions
What is the first accounting rule a founder should set?
One document archive and one monthly cut-off date. Without those two rules, every other control becomes unstable. See also: e-Residency vs power of attorney in Estonia.
When do we need monthly management reporting?
As soon as the founder needs to decide on hiring, pricing, or cash use based on current numbers rather than bank balance intuition. As stated in Commercial Code (ÄS), it is worth verifying the latest requirements before applying this step.
Should payroll be designed before the first salary run?
Yes. Payroll errors usually come from missing cut-offs and approvals, not from calculation formulas. As stated in EMTA employment register, it is worth verifying the latest requirements before applying this step.
Can we outsource from day one?
Yes, but only if the company still owns the document flow, approvals, and access rights.
What usually breaks in the second month?
Late document delivery, unclear treatment of founder expenses, and missing escalation for VAT or payroll edge cases. As stated in EMTA guidance on VAT, it is worth verifying the latest requirements before applying this step.
