Why you need a monthly calendar
SME accounting isn't a "whenever the receipt arrives" task — it is a predictable monthly rhythm dictated by strict statutory reporting deadlines. A well-structured calendar eliminates improvisation, reduces stress around the 25th of the month, and ensures nothing falls through the cracks. Here is the week-by-week ritual for an SME using local software or an ERP.
WEEK 1 (Days 1-7) — Closing the previous month
Day 1-2 (Mon-Tue):
Verify previous month closure — ensure all issued and received invoices are recorded, and all receipts and payments are reconciled with bank statements.
Adjusting entries — depreciation, foreign exchange differences, inventory adjustments.
Provisional trial balance — check that balances are consistent (receivables vs. unpaid invoices, payables vs. unpaid bills).
Day 3-5 (Wed-Fri):
Generate sales and purchase ledgers — see the correct printing guide.
Prepare VAT returns — deadline usually falls on the 25th; verify totals against the trial balance.
Prepare informative declarations — check transactions exceeding statutory thresholds (e.g., 5,000 RON for local reporting).
Prepare SAF-T D406 (if mandatory) — see the XML validation guide.
Day 6-7 (Weekend): Rest. Let the automation handle the heavy lifting on Monday morning.
WEEK 2 (Days 8-14) — Current operations + Payroll
Throughout the week:
Record incoming invoices — as they arrive (do NOT accumulate them until the end of the month).
Record bank statements — daily or every 2-3 days maximum.
Check e-invoicing portals — download newly received invoices from ANAF (the Romanian tax authority) SPV and import them into your system.
Day 10: Deadline for previous month's social security contributions. Verify the submission status.
Day 11-14:
Generate current month payroll — timesheets, calculations, payslips.
Payroll tax returns — preparation and verification.
WEEK 3 (Days 15-21) — Statutory submissions
Day 15: Deadline for paying payroll taxes and social contributions withheld at source. Compliance is mandatory to avoid penalties.
Day 15-20:
Submit payroll declarations (for the previous month).
Monitor e-invoicing returns — invoices rejected by the tax authority must be corrected and resent.
Interim reconciliation — cumulative bank statements vs. system records.
Day 21: Last window to correct SAF-T errors before the day 25 deadline.
WEEK 4 (Days 22-28) — The reporting rush
DAY 25 = CRITICAL DEADLINE:
VAT Return (previous month) — submitted via the official portal.
Informative declarations (previous month) — submitted via the official portal.
SAF-T (D406) — submitted via the tax authority portal (if applicable).
VAT Payment — transfer to the treasury.
Day 26-28:
Confirm submission status — verify that all filings are marked as "Accepted" (not just "Processed").
Correct rejections — any tax authority rejection requires a rectifying filing within 5 days.
Monthly PDF archiving (see organized archiving).
DAY 29-30 — Next month preparation
Complete database backup (see backup guide).
Software updates — apply any new versions containing legislative changes.
Clean up master data — inactive items, deregistered clients, unused accounts.
Management briefing — Top 5 financial indicators (turnover, monthly profit, receivables balance, payables balance, cash on hand).
Other calendar items (Quarterly / Annual)
Quarterly (March, June, September, December):
Corporate income tax advance payments.
Quarterly profit tax declarations.
Physical inventory counts (for companies with stock).
Annual (January-April):
Annual financial statements (submission by May 30 for the previous year).
Annual corporate tax returns (final profit/loss).
Dividend and micro-enterprise income tax filings.
Full fixed asset inventory + revaluations.
How to reduce time by 50%+
For an SME with 100-1,000 invoices/month, the calendar above represents 20-40 hours of manual work. With Azuvio layered over your existing system, we eliminate:
Manual entry of incoming invoices (automatically fetched from the tax authority, validated, and matched with POs).
Bank reconciliation (automated matching with fuzzy logic).
Live ledger generation (without manual runs).
SAF-T validation (zero errors at submission).
Typical savings: 50-60% of accounting time. See the Saga ↔ Azuvio connector or "When your software becomes too small".
Conclusion
A monthly accounting calendar equals predictability, zero missed deadlines, and zero tax penalties. Save this article and use it as your checklist. For a more relaxed rhythm: automate everything that doesn't require professional judgment (Azuvio does exactly that). See also the "2026 Tax Authority Calendar" for detailed statutory deadlines.
