What does one bank reconciliation really cost?

Ask a bookkeeping firm what a bank reconciliation costs and you will usually get a shrug, or a fee. The fee is what the client pays. The cost of a bank reconciliation is something else: the minutes of every person who touched it, the review, the rework and the emails in between. Very few firms have ever written that number down for a single task, which is odd, because it is the number that decides whether a fixed fee is profitable, where to put a new hire, and whether any AI tool is worth paying for.

This post costs one reconciliation step by step. The figures are illustrative, not research. The point is the method, which you can run on your own work with your own numbers in an afternoon.

Costing one bank reconciliation, step by step

Take a hypothetical bookkeeping firm and one client with a single main business account, reconciled monthly. A preparer does the work, a senior reviews it. Say the preparer's loaded cost (salary, employer costs, a share of overheads) is £30 an hour and the senior's is £55. Your own numbers will differ; use them.

Here is how the time might break down in an ordinary month:

1. Import and auto-match. Pull the statement or check the feed, let the software suggest matches, accept the obvious ones. 20 minutes.
2. Investigate the unmatched items. The card payment with no receipt, the transfer that covers three invoices, the refund booked to the wrong month. 60 minutes.
3. Client queries. Write the email, wait, chase, read the reply, chase again for the one item still missing. 30 minutes of actual effort, spread over a week.
4. Adjustments. Post the corrections and the reclassifications. 15 minutes.
5. Review. The senior checks the reconciliation, the unreconciled items and anything unusual. 20 minutes.
6. Rework. The senior's two questions come back and get fixed. 15 minutes.

That is 140 minutes of preparer time and 20 minutes of senior time. At the illustrative rates, about £70 plus about £18, so roughly £88 for one reconciliation, or a little over £1,050 a year for one account.

On its own that is not alarming. Multiply it by every account on every client, and a firm running, say, 150 of these a month is spending around £13,000 a month on one recurring task. Again illustrative. Your figure might be half that or double. You will not know until you count.

The matching is not where the money goes

Look at where the minutes sit. In this example the part people picture when they say "bank rec", importing and matching, is 20 minutes out of 160. The other 140 are exceptions, chasing, fixing and checking.

That pattern is common, and it matters for two reasons.

First, it tells you what to fix. If most of the cost is unmatched items, the question is why they are unmatched. Often it is the same three causes every month: a client who never sends receipts, a payment platform that bundles transactions, a supplier paid in one lump for several invoices. Those are rules. Rules can be written down, and once written down, they stop costing an hour each month.

Second, it tells you where any automation will and will not help. A tool that speeds up matching attacks the cheapest part of the task. The expensive part is the judgement about exceptions, and that only becomes cheaper when the know-how behind it is documented somewhere other than the preparer's head.

Per task economics beat per seat economics

Most conversations about AI in finance teams are framed per seat. A licence costs so much per user per month; is it worth it? That is the wrong unit. A seat is a person, and a person does dozens of different tasks, some of which any tool will help with a great deal and some not at all. Averaging across them hides everything useful.

Per task, the question becomes concrete. Before: 160 minutes and £88. After: how long does the review take, what does the agent or tool cost to run, and how many exceptions still come back to a person? If an agent drafted the reconciliation and a person approved it, as we described in drafts first, trust later, you could compare the two numbers month by month and see whether the handover is actually paying.

Per task numbers also answer questions that have nothing to do with AI:

• Pricing. If a client's reconciliation costs £88 and their fixed fee only covers £60 of bookkeeping, you know which clients to reprice, and why.
• Capacity. Hours per task, times frequency, gives you the real workload of the month, which is a far better guide to hiring than headcount ratios.
• Training. A task that takes one preparer 90 minutes and another 200 is not a performance problem. It is usually a documentation problem.

Where the returned hours go

It is worth being clear about the goal. Cutting the cost of a recurring task is not about needing fewer people. It is about the same team doing more of the work that grows the firm: taking on clients without a matching rise in the hiring plan, spending time on the advisory conversation the client actually values, and giving preparers a path to the work seniors do today.

The preparer who no longer spends an hour a month chasing the same missing receipts has not lost anything. They have lost the dullest hour of their month. If you say that to the team plainly, and early, they will also help you find the real costs, because they know exactly where the time goes.

How to cost your own tasks

You do not need a system to start. You need one task and one honest month.

1. Pick one recurring task with a clear start and end. A bank reconciliation is a good first choice.
2. Break it into five or six steps, as above. If you already have a list of your recurring work, as described in how to build your recurring task list in a week, start from that entry.
3. Ask the people who do it to note the minutes per step for one cycle. Rough is fine; guessed afterwards is not.
4. Apply a loaded hourly cost per role and add it up.
5. Circle the step that costs the most and ask why it costs that much.

Measured, rather than remembered, effort is the honest version of this. It is also why tools like Beaks record time from the work itself rather than asking people to estimate it.

One thing to do this week

Pick one client's bank reconciliation and cost it, with the minutes noted while the work happens. You will end up with one number and one circled step. The number tells you what the task is worth. The circled step tells you what to write down first, and that is the step that makes the task cheaper for whoever, or whatever, does it next.
