Pre-accounting: who owes what, what you owe, on one screen.
Customer and supplier accounts, invoices, cash & bank and cheques in one place. Aging splits overdue receivables into day buckets; cash flow, VAT and profitability reports come from the same data.
What Ön Muhasebe does
Current accounts
Receivable/payable status of customers and suppliers in one list. For each account: balance, currency, overdue amount and last-activity date.
Aging
Uncollected open receivables are split by due date: not-yet-due, 0-30, 31-60, 61-90 and 90+ days. It is clear which customer is delaying how much.
Invoices
Sales and purchase invoices line by line; VAT, discount and total calculated automatically. Each invoice is linked to an account and to collection.
Cash & Bank
Cash, bank, POS and credit-card accounts in one place. Collection, payment and transfer movements; each account live balance and ledger.
Cheques & notes
Cheques/notes receivable and payable are tracked separately; these amounts are not included in the cash-bank balance and turn into cash as they mature.
Cash-flow report
Incoming and outgoing cash compared per period; with expected collections and payments, the forward cash position becomes visible.
VAT report
Output and input VAT are totalled automatically from invoices; the period VAT position can be seen before the declaration.
Income-expense & profitability
Income and expenses by category; period profitability is produced from real movements, no manual table needed.
Period close
When a period is closed its records are locked; retroactive changes stay auditable and reconciliation is preserved.

1 dayPre-accounting software for SMBs
Pre-accounting is the system that keeps a business daily money movements — who owes what, what is owed, how much is in cash and bank — in one place. Most SMBs run this on Excel sheets that drift apart over time, turning month-end reconciliation into painful work. ERPKolay keeps pre-accounting in the same database as accounts, invoices, collections and stock, so the same figure is never entered twice.
Current accounts and aging
The current-accounts screen shows each customer and supplier live balance, currency and overdue amount in one list. The real value is in aging: uncollected open receivables are split into day buckets by due date (not-yet-due, 0-30, 31-60, 61-90, 90+). This table shows clearly which customer is delaying payment and by how much, and where collection pressure should be applied.
Cash, bank and cheques
Cash, bank, POS and credit-card accounts are gathered on one screen; each account opening balance, movement count and live balance are visible. Cheques and notes are tracked separately, and this is deliberate: cheques receivable have not turned into cash yet, so they are not added to the cash-bank balance, and cheques payable are not deducted yet. So the cash you see on screen is the cash you actually hold; cheques enter or leave the balance as they mature.
Reports: cash flow, VAT, profitability
Cash flow, VAT, income-expense and profitability reports are all produced from the same invoice and movement data. Because output and input VAT are totalled automatically from invoices, you can see your period position before the declaration; profitability comes from real income and expenses, not a hand-kept table. Combined with expected collections from won quotes and expected payments from the payment plan, the forward cash position becomes predictable.
Period close and auditability
When a period is closed, its records are locked. This prevents a past month figures from silently changing later and preserves reconciliation; every change leaves a dated, user-stamped trail. That traceability builds trust when handing data to an auditor or your accountant.

What does pre-accounting software cover?
Current accounts (customer/supplier receivable-payable), sales and purchase invoices, cash-bank movements, cheques/notes, plus aging, cash-flow, VAT, income-expense and profitability reports.
How is aging calculated?
Uncollected open receivables are split by due date from the remaining invoice amounts: not-yet-due, 0-30, 31-60, 61-90 and 90+ days. For each account, how much is overdue and by how long appears in separate columns.
Why are cheques not in the cash balance?
Cheques receivable have not yet turned into cash, so they are not added to the cash-bank balance; they are collected and added as they mature. Cheques payable are not yet deducted either. This keeps the cash position accurate.
Are multiple currencies supported?
Yes. Accounts and cash/bank accounts can be held in different currencies (TRY, USD, etc.); aging and reports are shown converted to the chosen comparison currency.
Are VAT and profitability reports automatic?
Yes. Output and input VAT are totalled automatically from invoices; income-expense and profitability are produced from real movements, so no separate table is needed.
What is period close for?
When a period is closed, its records are locked and retroactive changes remain auditable. This prevents reconciliation from breaking and silent changes to past periods.
Can I issue invoices?
Sales and purchase invoices are created line by line; VAT and discount are calculated automatically and the invoice is linked to the account and payment plan. E-invoice/e-archive integration is assessed during setup.
Is it linked to purchasing and stock?
Yes. Purchasing invoices and goods receipts feed from the same data as accounts and stock value in pre-accounting.
