It only finds what you thought to look for
A query written for last quarter's problem does not notice this quarter's. Nobody is looking at the systems nobody has complained about yet.
Stop comparing systems manually.
Reconcile once. Verify everywhere.
Mosaic automatically verifies that your business systems agree — across your entire data fleet, without moving your data.

all 3 checks passed · 2 patterns · 1 of 247 sources unread
One reconciliation — yesterday's sales, point of sale against ERP — run across a whole estate. The fourth row is missing. The fifth was never read, because that source did not answer, and Mosaic will not call those the same thing.
Reconciles the systems you already run
Still comparing systems by hand?
Somebody exports a CSV. Somebody writes the query again. Somebody opens Excel and checks the numbers, every morning, and phones a store when they don't add up.
It stops when the person does
The check happens when somebody has time. Holidays, handovers and busy weeks are the gaps discrepancies live in.
It cannot be handed over
The logic is in one person's spreadsheet and one person's head. Nobody else can run it, and nobody can prove what it did last Tuesday.
It does not scale past a few sources
One pair of systems is an afternoon. Two hundred stores is a job nobody is going to do by hand, so it does not get done.
One reconciliation. Every source.
Define what should agree once. Run it across ten sources, or a thousand, on a schedule — without writing it out again for each one.
Collections
A group of equivalent data sources — every store's point of sale, every regional warehouse — addressed as one thing. Add a store, and it is in every reconciliation that used the collection.
Your systems don't have to look alike
Database to API. API to warehouse. Spreadsheet to ERP. Mosaic does not care how the data got there — it verifies whether it agrees.
On a schedule, and quiet when it should be
Say what counts as agreement, then leave it. A run that finds nothing says nothing — which is what makes the mornings it does speak worth reading.
Mosaic runs where your data lives
Cloud, hybrid or on-premise. The reconciliation happens inside your own network, so the operational data being checked never has to leave it.
Reconciliation is its own question
Your data can be valid, your pipeline healthy and your transformation correct, and two systems can still disagree. That is the gap Mosaic exists for.
Data quality
Is this data valid?
Observability
Is my pipeline healthy?
ETL testing
Did the transformation work?
Monitoring
Is the system running?

Every one of the 16 differences in NET_TOTAL is exactly −2.00.
14 of 16 disagreeing rows are on Store 027 (88%).
IT defines what should agree
The sources, the keys that make a row the same row, the figures that ought to match, and the threshold that decides pass or fail. Written once.
Operations reads which things are wrong
A list, a difference and a source. No query, no schema, no credentials — the answer without the machinery that produced it.
Finance gets a number it can defend
Reproducible, exportable, and the same at 07:00 tomorrow as it was today.
Nobody has to ask you to run it
It ran at six. The people who needed it already have it.
Evidence, not guesses
Mosaic tells you what the data proves. It does not invent a cause, and it does not round a difference away to make a page look tidy.
It states the difference
Point of sale 12,400. ERP 11,920. Difference 480. Not a theory about which integration broke, unless the data proves it.
It separates absent from unread
A row missing from a system and a source that never answered are different findings with different fixes. Most tools report both as missing.
Every result is reproducible
The same run, the same rows, the same verdicts — exportable, and traceable back to the sources that produced them.
AI helps you get there, not decide
It suggests mappings and drafts queries. The source of truth stays the data, and the verdict stays arithmetic.
Can I trust what I'm looking at?
That is the question behind every dashboard, and the one a BI tool cannot answer about itself. Mosaic answers it about the systems underneath — so the number on the report is a number somebody has checked.
Publish the result, not a spreadsheet
One address the people who need it can keep, with the filters they may change.
Group reconciliations into one page
Sales, stock, payments, returns — a menu down the side, published together.

Start with one reconciliation
Take something you check by hand every morning and let Mosaic run it instead. One reconciliation, however many sources it has to reach.
