A Claude Code Skill for Bookkeeping Reconciliation: The Hours It Hands Back
Four hours a month matching bank lines at $60 an hour is $2,880 over 12 months. A Claude Code skill for bookkeeping reconciliation pairs the lines that agree and hands you only the ones that do not.
💵 The cost: Hours a month x your rate x 12.
🧾 The skill: A script pairs bank lines with ledger lines. You check the leftovers.
⏱️ The test: $250 pays back in about a month at 4 hours and $60.
What does reconciliation cost you over 12 months?
Multiply the hours you spend matching bank lines each month by your hourly rate, then by 12. At one hour and $40 that is $480 a year, at four hours and $60 it is $2,880, and at eight hours and $80 it is $7,680.
Try your own numbers
Count only the hours you spend matching. You still check the leftovers either way.
At 4 hours a month and $60 an hour, matching costs $2,880 over 12 months.
Think of a sock drawer: pairing the socks that plainly match is the slow part, and anyone can do it. The odd ones left at the end are the only ones that need your eye.
What a reconciliation skill does
A skill is a folder of written steps Claude Code follows. It can carry a script, so the pairing is done by code and the same two files give the same pairs.
↓
📒 2. You save the ledger for the same dates
↓
🔗 3. The script pairs lines with the same amount and date
↓
🔍 4. It flags near matches, same amount a few days apart
↓
📋 5. You get a short list of lines with no pair
What stays with you
| Job | The skill | You |
|---|---|---|
| Exact pairs | Pairs them | Nothing |
| Near matches | Flags them | Say yes or no |
| Lines with no pair | Lists them | Find out why |
| Changing the books | Never | Always |
Core insight: the skill writes a list and stops. Nothing in your books changes until you change it.
When it does not pay
Divide $250 by what a month of matching costs you. If the answer is more than 12, leave the chore manual.
Build
- 4 hours a month at $60: back in about 1 month
- 1 hour a month at $40: back in about 6 months
Skip
- 30 minutes a month at $40: over 12 months
- Your bank feed already pairs most lines
What does it cost to get one?
You can write one yourself for free with our step-by-step skill guide. Or keep the hours and have it built for a fixed $250, with the scope written before I start: get a custom Claude Code skill built.
This is the scope I would write, not a case study. The build service is new and has no independent case study yet.
- Scripts in skills: Claude Code skills docs, code.claude.com/docs/en/skills ("Skills can bundle and run scripts in any language").
- $250 fixed: the custom build page.
- Every other figure: arithmetic on example hours and rates you overwrite, not survey data.
