Monthly Close Checklist in 5 Days: AP, AR & Reconciliations Simplified

Closing the books doesn’t have to drag on for weeks. At FinSouthern, we’ve built closing routines for startups and SMBs that wrap up in five business days, without sacrificing accuracy.

A structured close not only gives leaders timely numbers, but also builds trust in reports by keeping the process transparent, repeatable, and audit-ready. The goal isn’t speed for its own sake, it’s about clarity, accuracy, and control.

The 5-3-2 Cadence

A five-day close works best with a 5-3-2 rhythm:

  • 5 days to complete the close
  • 3 streams of work: Accounts Payable (AP), Accounts Receivable (AR), and Reconciliations
  • 2 reviews: Controller sign-off on Day 4, leadership review on Day 5

This keeps focus sharp, reduces task-switching, and makes handoffs seamless.

Who Owns What

Every stream needs a clear owner:

  • AP Owner → Bills, approvals, accruals, and payment cutoffs
  • AR Owner → Invoicing, receipts, credits, and reserves
  • Reconciliation Owner → Bank, payroll, merchant accounts, fixed assets, and balance sheet tie-outs
  • Controller → Policies, approvals, and final close package
  • FP&A → Variance analysis and refreshed forecasts after the numbers lock

Clear ownership reduces delays and finger-pointing.

The Close Calendar

A successful close depends on predictable cutoffs. Publish a one-page calendar with:

  • Billing and usage locks
  • Bill intake deadlines
  • Payment runs
  • Review meetings

Set standard cutoff times so teams know what to expect every month.

Day-by-Day Close

Day 0 – Pre-Close Prep

  • Confirm bank feeds and downloads
  • Lock tax settings and price lists
  • Send reminders for timesheets, expenses, and approvals

Day 1 – Cash & Banking

  • Reconcile all bank accounts
  • Tie merchant settlements to fees and payouts
  • Apply receipts against open invoices

Day 2 – Revenue & AR

  • Confirm invoicing and lock usage
  • Post revenue recognition (time-based, usage, or milestone)
  • Record credits and adjust bad debt reserves

Day 3 – AP & Expenses

  • Collect and approve vendor bills
  • Accrue missing bills based on contracts
  • Post payroll, benefits, and prepaid schedules

Day 4 – Reconciliations & Controller Review

  • Reconcile all balance sheet accounts
  • Prepare variance notes with drivers and amounts
  • Controller signs off on recons and adjustments

Day 5 – Leadership Review & Publish

  • FP&A refreshes dashboards and forecasts
  • Package includes: P&L, Balance Sheet, Cash Flow, AR/AP agings, variance notes, and management summary

Standard Operating Procedures (SOPs)

AP SOP

  • One intake channel for bills
  • Approval matrix by amount and department
  • Maker-checker control for vendor bank changes

AR SOP

  • Standard invoice format with clear tax and due dates
  • Credit memos tied back to original invoices
  • Collections follow a set reminder plan

Reconciliation SOP

  • Standard recon template (opening, activity, ending)
  • Reconciling items must have owner + plan to clear
  • Items >30 days require controller comment

Controls That Protect Accuracy

  • Role-based access → Separate who sets up vendors, approves payments, and posts journals
  • Change logs → Chart of accounts, tax settings, and revenue rules documented with dates and approvals
  • Evidence on file → Every journal supported by memos, screenshots, or exports with standardized file names

Offshore + Onshore Model

Many founders use blended teams. Our best-practice split:

  • Offshore teams → Prepare cash posting, bills, invoices, and first-pass reconciliations
  • Onshore controllers → Review, approve, and handle judgment-heavy items

Daily standups + one central tracker keep the process clean and transparent.

Metrics That Matter

  • Close Time → Target: 5 days
  • On-Time Tasks → 90%+ checklist items completed on schedule
  • Recon Quality → Zero aged reconciling items beyond 30 days
  • Post-Close Adjustments → Low count = strong process

Common Issues & Fixes

  • Late usage or settlement data → Accrue with clear method, reverse next month
  • Net deposits booked as revenue → Break out sales, fees, and refunds separately
  • Unbilled but known expenses → Post accruals tagged with vendor + service
  • Revenue drift from contract changes → Add a contract change form with same-day routing

Building Continuity

  • Runbook & Templates → Calendar, SOPs, and sample entries kept current
  • Cross-Training → Quarterly role swaps ensure backups know the process

Conclusion

A 5-day close isn’t just an efficiency win—it’s a leadership tool. With the 5-3-2 cadence, clear owners, and standard SOPs, you get faster insights, fewer surprises, and more confidence in your numbers.

At FinSouthern, we help founders and finance teams turn chaotic closes into calm, predictable routines that scale.
