Switching profit trackers is easier than switching almost anything else in a store, because the orders live in Shopify rather than in the tool: any tracker worth using rebuilds the sales side from your own store history in its first sync. What does not come across is the work you did, which is the cost data, and that is the whole of the migration. This is the order to do it in, what you should export before cancelling anything, and the two things that genuinely will not transfer. Written by nouz, which is one of the destinations, and dated: any competitor figures mentioned were checked 1 Sep 2026.
- The sales history rebuilds itself from Shopify, so you are not losing orders by switching.
- Your cost rules are the asset. Export them before you cancel anything, in whatever form the old tool allows.
- Run both tools in parallel for one month and compare a single day end to end.
- Two things do not transfer: whatever the old tool computed for months you no longer have costs for, and any attribution model.
Export first, cancel later
The single mistake worth avoiding is cancelling before exporting. Take out unit costs per variant, shipping rates, payment fee rules, your fixed cost list and any manual ad spend, in whatever format is available, even if it is a screen you have to copy by hand.
Dates matter more than the figures. If the old tool holds any history of when a cost changed, that is the most valuable thing in the export, because it is the part that takes months to reconstruct and cannot be recovered from a supplier's memory. A price list with effective dates is the shape to hold it in.
What the first sync gives you for free
Orders, refunds, products, variants and payment transactions, back to the store's first sale, which means every revenue line is correct on day one. What is missing on day one is everything below revenue, because the new tool has no costs yet and will say so rather than guessing.
That is the right order to work in anyway. Get the revenue lines agreeing with your own expectations first, then add costs from the top down: goods, then fulfilment, then fees, then the fixed block, each one making one more margin real.
| Comes from | Effort | |
|---|---|---|
| Orders and refunds | Shopify, on first sync | none |
| Products and variants | Shopify, on first sync | none |
| Unit costs | your export | an afternoon |
| Shipping and fee rules | your export | an hour |
| Fixed costs | your own records | an hour |
| Historical ad spend | platform connectors or a CSV | minutes |
Run both for a month
Parallel running is cheap insurance and it is the only way to find the differences that matter. Pick one finished day, reconcile it end to end in both tools, and write down every discrepancy with its cause: a different VAT treatment, a refund booked to a different day, a shipping cost computed per order rather than per parcel.
Every difference you find is either a bug or a definition, and both are worth knowing before you rely on the new numbers. If two tools disagree by exactly your tax rate, you have learned something about at least one of them.
The two things that do not transfer
First, computed history for periods you cannot cost. If the old tool held costs you did not export, its margin history for those months cannot be reproduced anywhere, which is the strongest argument for exporting properly rather than quickly.
Second, attribution. If your old tool modelled which channel produced which order and you relied on that, understand that we do not build it at all and will not. Blended figures answer whether advertising pays overall; they cannot answer which ad did it, and pretending otherwise would be the wrong kind of migration promise.
The week, in order
- Day one: export everything from the old tool, especially any dated cost history, before touching a subscription.
- Day one: connect the store to the new tool and let the full backfill run.
- Day two: enter unit costs, then shipping, then fees, then the fixed block, checking a margin after each.
- Day three: connect the ad accounts, and import older spend with an ad spend import template where the connector cannot reach back.
- Weeks two to four: run both tools, reconcile one day fully, then cancel the old subscription once nothing surprises you.
What to expect afterwards
Numbers that differ slightly from the old ones, and the difference should be explainable rather than mysterious. Where the new tool prices costs with effective dates, a change closes the previous rule the day before and opens a new one, so your history stops moving when you edit a cost. What nouz costs is Base 69 euro, Pro 99 euro and Scale 249 euro a month, net, flat, set out in full under nouz's flat pricing, and the reasons a store leaves TrueProfit specifically are covered in TrueProfit alternatives, prices dated there too.
