ROI and Business Case

[YourCompany.com] · Finance Department · Prepared by FullSpec · [Today's Date]

This document shows you, in plain numbers, what your current accounts payable process is costing your business, what changes after automation, and whether the investment makes financial sense. FullSpec has built this case using the details captured in your process mapping session, cross-checked against benchmarks for businesses processing around 60 invoices per month. You do not need to do any calculations yourself. Read through each section and use the assumptions log at the end to flag anything you want to adjust.

01What the current process is costing you

The three highest-friction steps in your current process are the ones that consume the most time, introduce the most errors, and cause the most downstream delays. Each one compounds the others.

• Invoice Data Extraction (Step 2): 30 minutes per batch, repeated daily. The bookkeeper manually keys line items, totals, supplier names, invoice numbers, and due dates from PDFs. Poorly formatted documents cause frequent keying errors that only surface at month-end reconciliation. This is the single largest time sink in the process.
• Account Code Assignment (Step 4): 15 minutes per batch, every day. Coding decisions rely on the bookkeeper's memory of supplier history. New suppliers or unusual line items require a judgement call that varies by person, producing inconsistent coding across the chart of accounts and making financial reports harder to trust.
• Approval Request to Budget Holder (Step 6): 10 minutes to send, then hours to days waiting. The bookkeeper emails the relevant approver with invoice details and waits for a written reply. There is no structured reminder, no deadline, and no visibility over outstanding approvals. When approvers go quiet, invoices miss payment dates, late fees accrue, and early-payment discounts are forfeited.

02What changes after automation

After the build goes live, three agents handle invoice intake, coding, approval routing, bill posting, and remittance delivery end to end. The Invoice Intake Agent picks up every invoice the moment it arrives, extracts the data, and checks for duplicates. The Coding and Approval Agent suggests account codes from supplier history and routes a structured approval message to the right person in Slack, with automatic reminders built in. The Payment and Remittance Agent posts the approved bill to Xero, schedules the payment, and emails the remittance to the supplier without anyone lifting a finger. You keep one decision point: your bookkeeper reviews the small percentage of flagged exceptions, such as an unmatched PO, an unknown supplier, or an invoice an approver has queried. Everything else runs without manual input.

06Assumptions log

These numbers are built on your confirmed invoice volume of approximately 60 per month and a bookkeeper rate of $52 per hour. If either figure changes, the savings scale proportionally. A business processing 90 invoices per month would typically see manual processing time rise to 10 or more hours per week, pushing the annual staff cost toward $27,000 and increasing the net saving accordingly. Equally, if your actual hourly rate is lower, say $40 per hour, the annual saving reduces to approximately $13,000 but the payback period remains under five months because the build cost is fixed. The tool costs in the stack are largely fixed regardless of volume, so higher invoice throughput improves the return without increasing running costs.
