For many firms KPiR is where the tax story lives: income, deductible costs, depreciation, sometimes VAT beside it. We post from invoices and internal paperwork that actually reaches us, and we aim for consistency between the ledger and agreed tax registers. We do not second-guess borderline "is this deductible" questions remotely — those need business context and often a tax advisor’s opinion.

Entries come from source documents: invoices, bills, agreed internals. If a supplier description is vague or a line looks odd, we pause and ask rather than silently booking a fiction that collapses in review. We do not provide tax advisory on marginal deductibility; the entrepreneur ordinarily decides in cooperation with an advisor.
An asset starts with proper acquisition or production records, depreciation method and rate. We run depreciation schedules from data you confirm and from statute. Disposals, sales or mid-year corrections need a clean chain from opening balances to closing — we help keep that mechanical story straight in the books.
With VAT registration, sales and purchase registers should talk to invoices and to what eventually files as JPK. If documents arrive late, the feasible work is limited to what we hold. We watch calendar deadlines and communicate backlog risk; signing returns and filing corrections stay with you or your representative.
On request we prepare simple P&L-style slices, cost structure views or income categories by month or year-to-date — enough to feel trend before you commission heavy analytics. This is grounded in KPiR and related registers, not an open-ended BI warehouse.
