Monthly report
September 2026 at a glance
How the month went, what to decide and what moved your profit, written for the director.
This is a synthetic example: invented figures for an imaginary business, shown so you can see the format. It contains no client information. A client’s report is built from that client’s own records and approved by their consultant before it is sent.

September's growth did not reach the bottom line. Sales rose by £23,700 to £412,600, while operating profit fell by £13,700 to £38,400.
Most of the fall came from delivery costs. More of the work was done by contractors, whose day rates are higher than your own team's, so gross margin dropped from 44.8% to 41.2%.
Cash is healthy at £286,300, but it dipped because clients are paying more slowly.
Decisions this month
Three things to decide, and their financial impact.
Agree a day-rate cap with Northgate Associates before extending their contract
We recommend capping Northgate's day rate for the October extension, or moving the Brightwater project back to your own team from November.
Next step: Ask Northgate for their August and September invoices before agreeing the extension.
What it's worth
A cap at your current internal cost would add about £5,000 of gross profit a month.
Likely: Northgate's September invoices not yet seen
Evidence: appendix, points 4 and 5.
Invoice the approved time not yet billed
We recommend billing the approved time that has not yet been invoiced this week.
Next step: The finance lead raises the invoices from the matched timesheet list.
What it's worth
236 approved hours from July to September are on no client invoice; at agreed rates they total £18,400.
Firm: full timesheet and invoice records
Evidence: appendix, points 6 and 7.
Hold the third planned hire until gross margin recovers
We recommend holding the third planned hire for one month, until the contractor rate is settled.
What it's worth
The planned salary and on-costs are £4,900 a month.
Likely: depends on the first decision
Evidence: appendix, points 8 and 9.

Based on the dated client invoices and supplier bills in our cash schedule.
Payroll and tax payments are not all in the schedule yet, so treat this as a guide, not a forecast.
Opportunities worth discussing in our call
Where more could be made, and what happened since last month.
Bring debtor days back to target
Bringing debtor days back to target would release about £94,000 of cash. Three clients account for most of the slowdown.
Firm: full sales ledger
Review prices for clients on older rates
Each 5.0% increase for clients still on older rates would add about £3,100 a month.
Likely: rate cards not yet seen
Follow-through from last month
| Status | What we agreed, and what happened |
|---|---|
| Done | Agreed: chase the two overdue Fenwick invoices. The two overdue Fenwick invoices were paid in full in September. |
| In progress | Agreed: cancel the software subscriptions nobody uses. Four of eleven unused subscriptions cancelled, saving £640 a month. |
| Not started | No update recorded yet. |

How to read this report
We calculate every figure and chart in this report from your accounting records, and each one is checked independently before we approve the report.
Figures are rounded to the nearest £; totals use exact values.
Percentages are shown to one decimal place. A change in a percentage, such as gross margin, is given in % points.
Confidence: Firm means we checked the full records. Likely means the evidence points one way but a record is still missing. Open means we cannot say yet.
