A time tracking accounting export should let your books agree with your tracker without hand-copying every line. If it does not contain the right dates, references, rates, invoice context, and adjustment history, you end up rebuilding the same numbers twice and still not trusting either system.
The practical answer is not to force the tracker and the ledger to match every raw minute. The answer is to export enough structure that accounting can recognise the work, invoice it once, and keep the working record separate from the posted record. FlatHours is built for that sort of setup, and its pricing is flat, so the cost of keeping better records does not grow with the number of projects, clients, or tasks.
What a time tracking accounting export needs to contain
An export that is meant for accounting has a narrower job than a reporting export. Reporting can be useful with totals alone. Accounting needs the path from tracked work to billed work, because that is what lets you explain a number later.
At minimum, the export should contain the fields below. Some teams keep them in one file, others split them across time entries and invoice lines. The shape matters less than the presence of the information.
- A stable identifier for the time entry or grouped line item.
- The client and project names as they appear in the books.
- The work date, and the invoice date if the work has already been billed.
- The person or role that did the work, if rates vary by person.
- The task or work type, if different tasks carry different rates.
- The hours or minutes tracked, plus the rounding rule used before invoicing.
- The billing rate, or the method used to calculate it.
- Whether the line is billable, written off, or included in a fixed fee.
- The invoice number, if the work has already been posted to accounting.
- A note or description that a bookkeeper can read without opening the time tracker.
If you are tracking work for agency clients, that last item matters more than people think. A bookkeeper should be able to see why a line exists without asking the project lead to re-explain the job six weeks later.
What does not belong in the export
Do not push every internal field into the accounting file just because the software can carry it. Private comments, rough drafts, and anything that would confuse a tax file should stay out. Keep the export clean, then keep the fuller work history inside the tracker where it belongs.
That separation is also why it helps to have an invoice export that is boring on purpose. FlatHours can export to Xero on the Solo plan, and it keeps the accounting surface narrow instead of making you translate the same work through three different formats.
Where books and trackers usually disagree in a time tracking accounting export
The biggest mistakes are rarely dramatic. They are usually small mismatches that compound. The tracker tells one story, the invoice tells a second story, and the ledger ends up with a third.
| Topic | Tracker side | Books side | What to reconcile |
|---|---|---|---|
| Date | Time is logged on the day the work happened | Revenue is posted when the invoice is issued or recognised | Keep both dates and decide which one drives each report |
| Rounding | Entries may be rounded for billing | Books usually need the billed amount, not the raw minute count | Store the rounding rule and the post-rounding total |
| Adjustments | Work may be edited after review | Posted invoices should not keep changing | Export the final billed line, not just the first draft |
| Write-offs | Some tracked work is never billed | Books need to show the write-off or discount clearly | Carry the reason for the reduction |
| Rates | Different people or tasks may have different rates | Books need the rate behind the amount | Export the rate source, not only the final number |
| Grouping | Work may sit in many short entries | Books often want a cleaner invoice line | Preserve the link from grouped line back to source entries |
The table shows the real problem. Books are asking, “What was billed, when, and why?” The tracker is asking, “What happened?” Those are related questions, not identical ones. A good export answers both.
Timing is the first mismatch
Time trackers record when work happened. Accounting often cares when the invoice was sent, when payment was collected, or when revenue is recognised under your own rules. If you do not carry both dates through the export, you will get one report that looks right and another that does not.
That is where many teams start re-keying by hand. They are trying to make one system behave like the other. It is better to leave the systems different and export the bridge between them.
Rates and billable status are the second mismatch
In the tracker, a task can be billable in principle but not billed in practice. It can be included in a retainer, written off after review, or billed at a lower agreed rate. Books need the final treatment, not the raw intention.
This is where a tracker with per-person and per-task rates helps, because it makes the export less ambiguous. FlatHours Team includes both, and that makes it easier to send a clean record into accounting instead of reconstructing the billing logic later.
How to reconcile without re-keying
You do not need a second data entry process. You need one path from time entry to invoice line, then from invoice line to book entry. If that path is stable, the reconciliation becomes a check, not a rewrite.
- Pick one source of truth for the tracked work.
- Group entries only once, at the point where you invoice or post them.
- Export the grouped result with the original references attached.
- Keep the invoice number in both systems.
- Use the same client and project names everywhere you can.
- Store the final billed amount, not only the raw time.
- When something changes, post an adjustment instead of editing the historical record.
The last point matters. If you edit history, the books and the tracker will drift and nobody will remember which version was real. If you post an adjustment, the trail stays visible. That is what an accountant can work with.
For teams moving off another tool, the initial import matters too. FlatHours includes a full import from Harvest, however big. That means you can bring the old record across and then start exporting a cleaner one without rebuilding the backlog line by line.
When the export should be simpler than the tracker
There is a tempting failure mode here. People try to make accounting ingest the entire project system. That usually makes the export harder to trust, not easier. Accounting does not need every internal detail. It needs the business facts that affect the number on the invoice and the number in the ledger.
That is why a plain export is often better than a clever one. If the file can be opened, read, and matched to an invoice without a specialist explaining it, the export is probably doing its job.
The goal is not perfect symmetry between tracker and books. The goal is a clear trail from work done to money billed, with no manual re-entry in the middle.
That said, there is one honest limitation. If your process depends on custom revenue recognition rules, complex multi-currency posting, or a bookkeeper who insists on a very specific file shape, you may still need a mapping step outside the tracker. The export can carry the facts, but your accounting policy still decides how those facts are posted.
Why flat pricing matters here
Reconciliation work is already unglamorous. It gets worse when the software bills you more every time you add a project, a client, or a task. Then the price of keeping better records becomes part of the accounting problem itself.
FlatHours keeps that separate. Free is $0/month for one person. Solo is $5/month for one person. Team is $29/month for unlimited people. Annual billing charges 10 months for 12, and there is a 14 day trial. We never charge for invoices sent, projects created, clients added, tasks used, or a percentage of payments you collect.
That matters if you are building an operation where AI agents do billable work as well. The billing should be about the work, not about how many records you needed to keep the books straight. If you want the broader picture behind that, the billing for the work AI agents do page is the better companion piece.
The argument is simple. A useful time tracking accounting export should carry the final billed fact, the source work behind it, and the adjustment trail between them. If it does that, you do not need to re-key. You only need to reconcile.
