month-end-closing

# Month-End Closing Accrual reversal + depreciation + salary accrual. 3 calls total. ## Turn 1: GET accounts + GET postings (parallel, 2 calls) Example (adjust numbers from the prompt): ``` GET /ledger/account?number=1700,1720,5000,2900,6010,6030,1000,1005,1080,1100,1200,1209,1210,1230,1250&fields=id,number,name GET /ledger/posting?dateFrom=2026-03-01&dateTo=2026-04-01&fields=account(number),amount&count=500 ``` Put ALL accounts in this ONE call: every account from the prompt + 1000,1005,1080,1100,1200,1209,1210,1230,1250 (possible contra accounts). This is the ONLY account lookup — no follow-up GETs. From GET /ledger/posting: sum the amounts on the salary expense account (e.g. 5000) to get the salary accrual amount. Accumulated depreciation contra account mapping (pick whichever exists from the GET results): - 6000 (buildings) → 1080, 1100 - 6010 (transport) → 1230, 1249 - 6015 (machinery) → 1200, 1210 - 6017 (inventory) → 1250, 1270 - 6020 (intangibles) → 1000, 1005, 1080 ## Turn 2: POST ONE combined voucher (1 call) Combine ALL journal entries into a SINGLE voucher with 6 posting rows. Do NOT create separate vouchers. ```json POST /ledger/voucher { "date": "<last_day_of_month>", "description": "Månedsavslutning", "postings": [ {"date": "<last_day>", "account": {"id": <expense_acct_id>}, "amountGross": <accrual_amount>, "amountGrossCurrency": <accrual_amount>, "description": "Periodisering - reversering", "row": 1}, {"date": "<last_day>", "account": {"id": <prepaid_acct_id>}, "amountGross": -<accrual_amount>, "amountGrossCurrency": -<accrual_amount>, "description": "Periodisering - reversering", "row": 2}, {"date": "<last_day>", "account": {"id": <depr_expense_id>}, "amountGross": <monthly_depr>, "amountGrossCurrency": <monthly_depr>, "description": "Månedsavskriving", "row": 3}, {"date": "<last_day>", "account": {"id": <accum_depr_id>}, "amountGross": -<monthly_depr>, "amountGrossCurrency": -<monthly_depr>, "description": "Månedsavskriving", "row": 4}, {"date": "<last_day>", "account": {"id": <salary_expense_id>}, "amountGross": <salary_amount>, "amountGrossCurrency": <salary_amount>, "description": "Lønnsavsetning", "row": 5}, {"date": "<last_day>", "account": {"id": <accrued_salary_id>}, "amountGross": -<salary_amount>, "amountGrossCurrency": -<salary_amount>, "description": "Lønnsavsetning", "row": 6} ] } ``` monthly_depr = acquisition_cost / useful_life_years / 12 (round to 2 decimals). **3 calls, 0 errors.** ## STRICT RULES - GET /ledger/account: ONE call with ALL account numbers comma-separated. NEVER make separate lookups. Include the wide net of contra accounts listed above. - ONE single POST /ledger/voucher with ALL 6 posting rows. Do NOT create separate vouchers. - Skip trial balance verification — it's read-only and not scored. - All dates: last day of the month. - No voucherType needed. - Salary amount = sum of postings on the salary expense account from GET /ledger/posting.
