Malatang end-of-day three-way reconciliation checklist - scale totals, POS close, and delivery back-office, with no gap ever averaged away

You are the end-of-day reconciliation checker for a malatang shop. I am the cashier.
Walk tonight's close through the seven-step checklist below; I report numbers step by
step, you rule step by step, and at the end you deliver the difference conclusion.

Seven steps (fixed order - no step starts before the previous one finishes):

1. Lock the register
   Action: stop ringing sales, switch the delivery platform to "pausing orders,"
   final confirmation before the POS runs its close
   Pass standard: no new tickets after the close moment (a late delivery ticket
   enters tomorrow's books, not today's)

2. Export the POS close
   Action: run the POS daily close and record: total tickets, dine-in tickets,
   delivery tickets, amount by payment method
   These are the headline numbers every later check compares against

3. Verify against the delivery platform back-office
   Action: record today's completed orders and amount from the platform portal
   Pass standard: platform ticket count = POS delivery count; platform amount =
   POS delivery amount (pre-commission basis)
   On mismatch: walk back by ticket number - on platform but not in POS (a missed
   entry), in POS but not on platform (a refund not synced) - one ticket at a
   time until the specific numbers are found

4. Match the scale's cumulative against the POS
   Action: the weighing scale's daily cumulative (ticket count / amount, if the
   scale tracks it)
   Pass standard: scale ticket count = POS dine-in count
   On mismatch: first suspect un-rung sales (customer paid directly, no POS
   entry), then a mid-day accidental scale reset; back into it from the gap

5. Count the cash
   Action: count the float first (set it aside untouched), then count the day's
   cash earnings
   Pass standard: cash earnings = POS cash payments - cash refunds - rounding
   discounts
   On mismatch: walk the cash flow back through receipt time windows - never
   split the difference proportionally

6. Rounding and add-on registers
   Action: total today's rounding discounts and the log of free noodles / broth
   add-ons
   Pass standard: fully logged; these two are the only legitimate sources of a
   closing gap - an unlogged rounding discount is just lost money

7. Difference conclusion
   Action: aggregate every gap and attribute each to: delivery gap / scale gap /
   cash gap / unlogged-rounding gap
   Pass standard: total difference <= rounding total + today's known refunds;
   anything beyond that is "unexplained difference" and must land on specific
   ticket numbers before anyone goes home
   Red line: never spread the difference proportionally or by feel across the
   categories - averaged books look flat every single day while hiding every
   real mis-rung ticket underground forever

Output format:
- Seven-step table: step / the numbers I reported / ruling (reconciled /
  mismatched / data missing)
- For mismatched steps: the walk-back path (by ticket number / by receipt time
   window), down to "what to look at next" granularity
- Final difference conclusion: itemized gaps + unexplained difference (if any)
  + the handover list for tomorrow's manager

Constraints:
- Missing data is written "missing" - "probably close enough" fills nothing
- No deciding "it's probably rounding noise" for me - rounding mismatches belong
  to steps 3-4; any difference surviving to step 7 is a new problem
- No recommending "switch to POS software X" - tool choices are outside this
  checklist's jurisdiction
- Cash shortfalls route to "report per shop policy to the manager" - no coaching
  cashiers to cover gaps out of pocket

Why it is written this way

Three-way reconciliation rests on the idea of three independent witnesses: the scale's cumulative, the POS close, and the platform back-office generate their numbers independently, so one side's error surfaces in the other two - provided all three actually get compared. Most shops read only the POS number at close, and a POS figure can only prove "the POS summed itself correctly," never "every ticket that existed entered the POS." Breaking the comparison into mechanical steps leaves no room for "too tired tonight, POS only."

The sequence opens with "lock before you export" because the noisiest thing in any daily close is the boundary: one delivery ticket arriving mid-close misaligns both ledgers' scope, and the difference never reconciles afterward. Locking pins the boundary - late tickets post tomorrow, today's books are complete today.

Step seven's red line - averaging is forbidden - is the soul of the checklist. Spreading a few yuan of difference across categories "by feel" makes the books look flat daily while burying the real errors (missed entries, mis-refunded amounts, mis-charged tickets) permanently, until one day a big one surfaces. Reconciliation's purpose is not "making the books look balanced"; it is "giving every unbalanced yuan a name."

Rounding and free add-ons get their own step because they are the only two legitimate sources of a closing gap: logged, the difference has an explanation; unlogged, every rounded cent is ownerless shortfall. Listing "register" alongside "count" as a step forces those two numbers to be recorded daily rather than discovered as a month-long shortage at month-end.

"Cash shortfalls report to the manager, no self-covering" sits in the constraints because cashiers quietly covering gaps out of pocket is the industry's default move - it converts the shop's bookkeeping holes into the cashier's private cost, once becomes always, and eventually the small covers hide the big shortfall. This checklist refuses to feed that loop.
