How Chai & Crumbs cut 7.5 hours of admin a week — without dropping a single shift.

A 5-staff independent café in Birmingham switched to ZayPOS in May 2026. We sat down with the owner two weeks in and measured the real numbers — rotas, supplier invoices, EHO logbook, Natasha's Law allergen labels — hour by hour.

The numbers, in one paragraph

Indicative weekly time saved across the four tasks the AI features cover. The 60-day guarantee promises 5 hours a week — Chai & Crumbs is winning back 7.5. The extra 2.5 are the cushion that makes the guarantee easy for us to offer.

Before vs after

Two weeks into the switch. Same café, same five staff, same supplier list. Everything in the right-hand column happens automatically or in a single tap.

Before ZayPOS

  • Rota built every Sunday on a Google Sheet — copy-paste from last week, then 30+ WhatsApp messages for swaps
  • Supplier invoices typed into a stock spreadsheet by hand every Monday morning
  • EHO temperature checks logged on a paper clipboard pinned to the fridge — lost twice in 2025
  • Natasha's Law allergen labels designed in Word, reprinted whenever the menu changed
  • Separate payroll app (£28/mo) reconciled against till-end-of-day reports by hand
  • Three different apps open at any time: POS, rota, stock

After ZayPOS Complete

  • Rota auto-generated Sunday morning from the sales forecast — owner approves or tweaks in 5 minutes
  • Photograph of each supplier invoice → AI keys it into stock & updates prices — reviewed in 2 minutes
  • EHO temperature checks logged on iPad with date/time/staff stamp — one-click "Food Inspector Pack" generates the full report
  • Allergen matrix is part of every menu item — labels print on demand, change once and the matrix updates everywhere
  • Tips and wages reconcile inside ZayPOS — HMRC RTI submission triggered from the same screen
  • One app. Owner uses her existing iPad behind the counter.

What changed, task by task

Each of the four big wins, in plain terms.

1. Staff rotas — ~3 hours/week saved

Before: Sunday morning ritual. Pull last week's Google Sheet, copy the structure, redo the cells, then send WhatsApp pings to the team to confirm. Mid-week, two people would ask to swap shifts — reshuffle, re-message, reprint the rota on the staff-room board.

After: ZayPOS reads the previous four weeks of sales data, predicts how busy each shift will be, and proposes a rota that matches staff availability. The owner reviews, tweaks the two shifts that need a specific person, and publishes. Staff get notified by SMS automatically. Swap requests happen in-app — manager taps approve, both rotas update, no reprint needed.

2. Supplier invoices — ~2 hours/week saved

Before: every Monday, the owner sat with a stack of paper invoices and typed each line item into a stock spreadsheet. Item, quantity, cost. Then updated retail prices if the cost had moved. Then archived the paper. Roughly 90 minutes if it was a quiet week, 2.5 hours if a big delivery came in.

After: when the delivery arrives, the staff member who signs for it takes a photo of the invoice with the till iPad. ZayPOS reads it, matches the line items to existing stock SKUs, updates quantities and cost prices, and flags anything ambiguous for the owner to confirm. Owner reviews in 2 minutes the next morning. Original invoice photo is archived against the supplier record.

3. EHO logbook + Natasha's Law — ~1.5 hours/week saved

Before: paper clipboard on the fridge for temperature checks. Paper opening/closing checklist. Allergen matrix was a Word document on the shared drive that no one updated when the menu changed. Two separate apps tried — one £35/mo, one £42/mo — both were dropped because the data didn't connect to the till.

After: ZayPOS prompts the duty manager twice a day to log fridge and freezer temperatures (with staff name, time and any corrective action recorded). The opening/closing checklist runs from the same iPad. The allergen matrix lives inside each product — change a recipe once, every label, every QR menu, every printed receipt updates automatically. When the EHO turns up, the "Food Inspector Pack" button generates a PDF covering everything an inspector will ask for.

4. Payroll reconciliation — ~1 hour/week saved

Before: separate payroll app (£28/mo). At the end of each pay period, the owner exported staff hours from the rota app, imported them into payroll, then exported tips totals from the till reports, then reconciled tips-to-staff manually before pressing send on HMRC RTI.

After: rotas, hours worked, tips collected and payroll all live in ZayPOS. End-of-period: review one screen, confirm tips allocation (which now follows the rule the owner set once), submit RTI. The separate payroll app got cancelled in week one.

In the owner's words

A short quote from the filmed walk-through. The full clip will land on this page later this week.

The thing I didn't expect was how much of my Sunday morning came back. The rota used to eat 90 minutes minimum and put me in a bad mood before the week even started. Now I review what ZayPOS suggests, change two shifts, and I'm done before my coffee's cold.

The invoice photo thing felt like a gimmick when they showed me. It isn't. I haven't typed a supplier invoice into a spreadsheet in twelve days.

The 60-day guarantee, in context

The numbers above are why the guarantee exists. We promise 5 hours a week back. Chai & Crumbs is getting 7.5. The 2.5-hour gap is our safety margin — and the answer to "what if your café isn't typical."

Try ZayPOS for 60 days from your first paid charge. If you don't save at least 5 hours a week on rotas, supplier invoices, EHO logbooks and Natasha's Law allergen updates — combined — we refund every penny. No interrogation, no retention call.
