SOP for Accounts and Finance Department in a Manufacturing Company

Last updated: 22 October 2026

Quick Answer: An SOP for the accounts department in a manufacturing company is a written procedure for payables, receivables, payroll, cash and bank, month-end close and MIS. Once approved, it fixes the owner, documents and deadline for each task. Two statutory anchors shape it: the 45-day cap on paying micro and small suppliers and the 30 November input tax credit cut-off.

A manufacturer's accounts team handles high invoice volumes, purchase returns and statutory deadlines at once. A written procedure turns that load into repeatable steps with named owners, so every figure traces to a document and a person.

What should an SOP for the accounts department cover?

A workable SOP covers the whole transaction cycle, not only voucher entry. Each section should state the purpose, the documents required, the step-by-step process, the control point, the exception route and the record retained.

Where a judgement is needed, such as provisioning or a write-off, the SOP should name the person who decides and the limit of that authority.

Who should prepare the SOP and who approves it?

The accounts head or finance controller should prepare the draft, because that role sees where vouchers stall and which controls fail in practice. Process owners in purchase, stores and dispatch confirm the steps that touch their documents, and the MD or the board approves the final version.

Each accounts staff member signs an acknowledgement. Date every version and keep superseded copies, so an auditor can see which procedure applied in a given month.

How does an SOP for accounts payable work in a plant?

An SOP for accounts payable in a manufacturing company rests on one discipline: no invoice is entered or paid unless it matches the purchase order and the goods receipt note.

1. Receive and stamp the supplier invoice on the day it arrives, with a sequential inward number.
2. Match three documents: purchase order, GRN and invoice, line by line for quantity, rate and tax.
3. Route mismatches back to purchase or stores for resolution, and record the resolution in writing.
4. Enter the invoice in the books with the correct account head, tax code and due date.
5. Release payment only through the approved payment run, with dual sign-off above a stated limit; larger plants often add an independent check of vendor payments before release.

Which statutory deadlines does the payables SOP track?

Section 15 of the Micro, Small and Medium Enterprises Development Act, 2006 requires a buyer to pay a registered micro or small supplier by the date agreed in writing, which cannot exceed 45 days from acceptance or deemed acceptance, or, where no date is agreed, within 15 days of acceptance or deemed acceptance.

Paying late costs twice: section 16 of the same Act gives the supplier compound interest, with monthly rests, at three times the bank rate notified by the Reserve Bank, and section 37(2)(g) of the Income-tax Act, 2025 defers the deduction to the tax year of payment. Companies with such payments pending beyond 45 days file MSME Form-1, a half-yearly return to the Ministry of Corporate Affairs, by 31 October and 30 April. Under section 22, audited accounts must also disclose the principal and interest still unpaid at the year end. Since 15 October 2026, missing that disclosure draws a warning, then a ₹10,000 to ₹50,000 penalty, then a ₹50,000 to ₹1 lakh fine, under section 27(2) as substituted by the MSMED (Amendment) Act, 2026.

On the tax side, section 16(4) of the Central Goods and Services Tax Act, 2017 ends input tax credit on an invoice at 30 November after the financial year, or the annual return date if earlier, so a late-booked invoice can lose credit even for a genuine purchase. Credit is also taken only on invoices the supplier has reported, and credit on an invoice still unpaid 180 days after its date, other than a reverse-charge supply, is paid back with interest, then taken again once the supplier is paid.

What belongs in an SOP for accounts receivable?

An SOP for accounts receivable should control credit before it controls collection. Every new customer needs a credit limit approved at a defined authority level, and every dispatch needs a check that the limit is not breached. The tax invoice should be issued before or at the time the goods leave the plant, as section 31 of the Central Goods and Services Tax Act, 2017 requires, and matched to the sales order and the dispatch record. Where the company is covered by e-invoicing, the invoice must carry an invoice reference number from the invoice registration portal before the goods leave.

The SOP should fix a weekly ageing review, a first reminder at a stated number of days past due, and an escalation ladder up to the MD. Provision for doubtful debts follows a written policy. For distributors and depots, a monthly balance confirmation signed by the counterparty stops disputes ageing silently.

How is the month-end close run to a fixed calendar?

The SOP should list every close task with an owner and a due day, and the accounts head should sign off a completion checklist before the trial balance is frozen.

• Day 1 to 2: stop entries to the closed month, complete bank and cash reconciliation.
• Day 2 to 3: reconcile physical stock with book stock, and value closing stock per the costing policy.
• Day 3 to 4: accrue unpaid purchase and expense invoices, and account for goods received but not invoiced.
• Day 4 to 5: compute depreciation from a fixed asset register verified physically on a cycle, post payroll cost and reconcile statutory ledgers.
• Day 5 to 6: review the trial balance with the finance controller and lock the period in the software.

How does the close handle stock, work in progress and job work?

The close should value raw material, work in progress and finished goods by the costing policy, and confirm goods lying with job workers against the job work challans and the job workers' own statements. Scrap and by-product sales need a register reconciled to the weighbridge or dispatch record. Before the trial balance is frozen, the costing profit and loss should be reconciled to the financial profit and loss, with each difference explained.

What goes into the monthly MIS pack for management?

The SOP should specify the MIS pack's contents, cut-off and due date. A useful pack for a manufacturer holds the profit and loss statement against budget, a cost-per-unit trend, working capital and bank position, receivable and payable ageing, and a stock summary by item class.

It should also note any line that moves beyond a stated percentage, with the reason and action, and list next month's statutory filings and dues.

What does an SOP for finance department work add?

An SOP for the finance department usually adds four procedures:

• Cash forecast: a rolling forecast for the coming weeks, updated weekly from the payables and receivables ageing.
• Bank limits: the monthly stock and book-debt statement to the lender, prepared from the closed books and reconciled to the drawing power allowed.
• Budget: an annual budget by cost centre, with variances explained in the MIS.
• Capital expenditure: a written approval route by value, from request to the fixed asset register.

How does the SOP keep the audit trail and records compliant?

The proviso to rule 3(1) of the Companies (Accounts) Rules, 2014 requires every company that uses accounting software, for financial years from 1 April 2023, to use software that keeps an edit log of every change, which cannot be disabled. The statutory auditor reports on it under rule 11(g) of the Companies (Audit and Auditors) Rules, 2014, and ICAI's implementation guide on rule 11(g) sets out the checks. The SOP should therefore forbid backdated edits outside a documented correction route.

Vouchers with supporting documents, reconciliations, registers and signed close checklists are filed by month, kept for at least eight years as section 128(5) of the Companies Act, 2013 requires for books of account, and retrievable within a stated time.

How does a small accounts team keep duties apart?

Whoever enters a vendor should not release its payment, and whoever maintains the cash book should not reconcile the bank account. Where the team is too small for full segregation, as in a three-person accounts office, the SOP should name a compensating review by someone outside the entry chain, usually the MD or a director, who checks the bank statement, the payment run and every change to the vendor master each month.

What should trigger a change to the accounts SOP?

Review the SOP once a year, and immediately after a change in law, accounting software or plant structure, such as a new warehouse or ERP module. The accounts head runs the review and the MD initials the changes.

Internal audit findings are a ready-made review input, and so are the internal financial control weaknesses the statutory auditor reports: each repeat finding usually points to a step that is missing, unclear or bypassed.

Who can help draft and test these procedures?

The draft can come from the company's own finance controller, an accounts outsourcing firm, a virtual CFO service or a management consultant. Astral Business Consulting LLP, a Coimbatore-based management consulting and audit firm, prepares accounts SOPs through its Best Accountant division, whose listed work includes SOPs, an authority matrix and defined roles. Its process-based internal audit also covers Accounts and Finance.
