TraceBenchBY SMARTFACTFREE LOT AND BATCH TRACEABILITY
Updated
A mock recall is a planned exercise that tests your traceability: you choose a lot and check how quickly and fully your records show where it went and what went into it. TraceBench does the tracing part free in your browser, from your own production and despatch exports, with the row behind every link and every gap named.
Free to use. No account, email address or trial. Your files are never uploaded.
Whether your records can answer two questions quickly and fully: where did this lot go, and what went into it? Customer and certification audits often also expect quantities to be reconciled and a time limit to be met. TraceBench answers the tracing questions from the records you load; reconciling quantities stays a separate check in your own system.
Usually two exports: production records that state which input lot went into which output batch, and despatch records that state which batch went into which shipment. Load each as a UTF-8 CSV and say what it records. A goods-in file on its own shows what arrived, not where it was used, so it cannot answer where a lot went.
Scan or type the lot number exactly as recorded, choose the starting record and Forwards: where did it go?, then Run this trace. To cross from production into despatch, first confirm under Links between the two files that the batch codes in both refer to the same batches. The result lists every reached batch and shipment, and every link opens to its file, record number and original cells.
TraceBench says so. A missing sequence number in a range you declared, coverage you are not sure of, or a code in the other file that nobody has confirmed as the same batch leaves the result Partial or Unknown, with the reason named. A code with no match is reported as No recorded match within what you loaded, never as proof that it was not made or not shipped.
Download the trace as an A4 PDF or a CSV. Both hold the exact question, every link with its rows, the gaps, the separate project warnings and each file's name and SHA-256 fingerprint. Keep the trace in the project history and download a backup, so the exercise can be reopened later with the same files and decisions.
It does not decide whether to recall, hold stock or notify customers, and it does not reconcile quantities or time the exercise. It reads only what the loaded files record, two files at a time, with no connection to your ERP. A result describes the records, not what physically happened.
For quality and technical managers at small food and engineering manufacturers preparing for a customer audit, a certification audit or their own traceability test.
A USEFUL STARTING POINT
In a mock recall it is easy to fill a gap from memory, or to join two spreadsheets on a code that only looks the same. TraceBench follows the links your files record and the ones you confirm, shows the row behind each and keeps every gap in the answer, so the exercise tests your records rather than your memory of them.
FROM QUESTION TO EVIDENCE
Export the production and despatch records for the period, load them as CSV files and say what each column means, including the numbering each code uses and what the file covers.
Scan or type the lot, choose Forwards: where did it go? and run the trace. Confirm a link between the two files only where you know the codes refer to the same batch.
Read the gaps, download the PDF or CSV for the exercise file, keep the trace in the project history and download a backup.
In the built-in example, which declares that both files use the same batch numbering, the records show supplier lot SL-0042 going into batches B-1001 and B-1002, and those batches in shipments S-501, S-502 and S-503. The production file declares sequence numbers 6 to 8, but number 7 is missing, so TraceBench reports the trace as Partial and names the missing sequence. It does not assume the missing record was unimportant.
USED IN PRODUCTION
TraceBench answers one question at a time, from files you load on one device. When traces become regular work for a quality team, LotTrail keeps the declared sources, reviewed identity links and evidence together. LotTrail is an invited trial, with scope agreed with you.
Invited trialLotTrail follows a lot or serial number through the records your factory already keeps, with the source of each link and the gaps shown. Sources are declared, mappings are reviewed, identity links are approved by a supervisor and the evidence is retained for quality work. The invited trial covers two declared sources at one site.
BEFORE YOU START
No. Quantities appear only as they are written in the original rows, and TraceBench never adds, allocates or reconciles them. Where several inputs share one production operation, every input may relate to every output, and TraceBench labels that as potential attribution instead of dividing the quantities.
Yes. Enter the shipment number from the despatch records and trace backwards: TraceBench follows the shipment's recorded contents to the batches and supplier lots behind them. A shipment can only be traced backwards.
It is a record of what your files show. The PDF states the question, the files and their fingerprints, every link and every gap. A fingerprint shows that a file has not changed since it was loaded; it does not show that the records are true or that they cover everything that happened.
TraceBench is a reading of the records you load, not a recall decision or proof of what physically happened. It has no recall, hold, stock or customer-notification actions, does not allocate or reconcile quantities, and never links records because their codes, times, descriptions or row order look alike. Two current files at a time, each UTF-8 CSV with column names in the first row, up to 5 MiB, 5,000 data records and 40 columns, and 10,000 recorded facts across both. A trace follows up to 20 manufacturing steps and stops at its limits with a stated reason. XLSX files are not read, and there is no connection to your ERP or any other system.
Your files stay in this browser. Work is held in memory until you choose Save on this device, which keeps the whole project, original files included, in this browser. Files are read and fingerprinted on your device and never uploaded, and there is no account or email step. Reports and backups contain your records and file names, so check them before sharing. Google Analytics is optional and loads only after you accept; it never receives codes, rows, file names or results. Use Analytics settings to change your choice; see /privacy/.
