Three artefacts, one derivation: the pack that went in, the batch that recorded it, the label that proves it.
One label is all it takes.
Since October 2021, food packed on site before it's ordered must carry a full ingredients list with the 14 regulated allergens emphasised. That's Natasha's Law, and it applies to a market stall exactly as it applies to a supermarket.
Most small food businesses manage this with a spreadsheet, a late night, and hope. The label gets typed by hand, from memory, from the recipe as it was written, not the batch as it was made. Swap to a different brand of chocolate on the day and the label quietly stops being true.
ProvenBatch removes the typing, and with it the gap. Labels are derived, never written by hand, so a label can never disagree with what went in the mix.
Three steps to a label you can stand behind
1
Photograph your packs
“Snap now, and I’ll read it. Sort it out later.”
Snap the ingredients panel and ProvenBot reads the declaration back to you, word for word. Check it against the pack and confirm. Do a few each time you put a delivery away, and you’ll type almost nothing.
2
Build your recipes
“Twelve lines, matched to your ingredients.”
Paste a recipe, link one, photograph a book page or drop in a PDF. The lines are matched to your ingredients: quantities converted, sections kept. Costing runs live from your real pack prices.
3
Batch and print
Pick which supplier's pack actually went in today. The label, allergens included, rebuilds from that pack, prints on your labels, and the batch is recorded forever.
This is the moment the label becomes proof.
The whole loop in 79 seconds: real app, real data. More on our YouTube channel.
Derived from the batch, not the recipe
Every other tool derives the label from the recipe. ProvenBatch derives it from the batch that was made: at batch time you choose which supplier's pack actually went in, and the label rebuilds from that pack's declaration. If the alternate brand declares different allergens, you're warned before you continue.
Recording a batch stores an immutable snapshot of exactly what was printed and which pack went into every ingredient — an audit trail built as you work, not reconstructed when someone asks.

Swapped from usual — declares the same allergens ✓
Software that checks its own work
Allergens are detected automatically and never trusted: everything arrives unverified until you confirm it against the pack. An independent second-opinion scan re-reads every declaration with a different rule set and flags disagreements.
Append-only history nobody can edit. Including you. That's the point.
The typing is removed
This is ProvenBot. He does the reading.
Photograph a pack and he reads the declaration back to you, word for word. Photograph a receipt, or forward the PDF from your inbox, and the expense arrives matched and pre-filled, with price rises flagged against your costings.
He reads, he never decides. Nothing he finds is ticked for you, and he can't change a record. Only you can.

If the FSA recalls something you buy, you'll know by morning
Every night we read the Food Standards Agency's allergy alerts and product recalls and check them against the supplier products in your own catalogue. If one matches, it's waiting on your Today screen when you open the app, with the FSA's notice and the product it matched.
Nobody sends you a letter when a supplier reformulates or a batch is withdrawn. This is the part that watches for you.

If you pack food where you sell it, this law is yours
PPDS is critical for many small food businesses. The FSA publishes guidance for bakers, butchers, caterers, farm shops, delis, market stalls and preserve makers alike, all in scope on the same terms.
Home bakers & cake sheds
Photograph packs instead of typing; costing that stops underpricing.
Caterers & meal prep
Plan a production day as a session; print every label set in one go.
Farm shops & food halls
Swap a supplier and the label follows; shopping lists by supplier.
Delis, cafés & sandwich makers
Fast reprints from stored snapshots; uncertain batches blocked.
Butchers
Compound ingredients declared properly; use-by handled per product.
Preserves, chocolate & sauces
Offline capture at the market; per-batch records at stall scale.
Restraint is the feature
Your data is held in the UK
Database, files and accounts live in the UK. Where photos or voice notes are read by AI, we say so plainly, and it's disclosed in full in our privacy notice.
Never held hostage
Stop paying and your account becomes a read-only archive: everything visible and exportable. We will never lock a food business out of its own allergen records.
No per-label fees. Ever.
Label everything; that's the point. No setup fees, no per-user fees below your tier, cancel monthly.

Asked and answered
Does ProvenBatch make my labels legally compliant?
No software can promise that, and you should be wary of any that does. Legal responsibility for a food label always rests with the food business operator: you. What ProvenBatch does is make it much harder to get wrong: labels are derived from your real data, uncertain batches are blocked rather than guessed, and everything is recorded so you can prove what you did.
What happens when my trial or subscription ends?
Nothing is billed and nothing is deleted. Your account drops to a read-only archive: everything stays visible and exportable. Printing stops; your allergen history doesn't vanish. More about the free trial.
Is there a per-label charge?
No. Label everything; that's the point.
