A daily till record in a Korean telecom retail store is not a simple cash count. It is a compressed summary of the day's revenue across three or four distinct income streams, each with different timing, different verification paths, and different implications for your monthly settlement position. Reading it correctly takes about five minutes when you know what each line is telling you. Reading it wrong, or not reading it at all, is how small discrepancies accumulate into month-end surprises.
This post walks through the main line items in a typical daily till summary and explains what each actually measures, what it does not measure, and what a deviation from expectation usually means.
Gross device sales versus net device revenue
Gross device sales is the total face value of all handset transactions processed during the day, including the carrier subsidy component. If a handset retails for 1,200,000 KRW and the carrier is contributing a 400,000 KRW subsidy (공시지원금), the gross device sales line will show 1,200,000 KRW.
Net device revenue is what remains after subtracting the subsidy pass-through. In this example, net device revenue is 800,000 KRW: the portion of the handset price covered by the customer's payment or financing agreement, excluding the carrier's contribution. The carrier subsidy is not your revenue; it is a pass-through you handle on behalf of the carrier and recover through the settlement process.
The distinction matters because if you look only at gross device sales, you will consistently overestimate your store's actual revenue from device transactions. The subsidy component can be anywhere from 200,000 to 600,000 KRW per device depending on the carrier plan tier and the promotional cycle, which means gross and net can diverge substantially on days with heavy activation volume on subsidized models.
Activation count broken down by type
A good daily till record shows activation count segmented by 신규 (new subscriber), 번호이동 (number port-in), and 기기변경 (device change on existing plan). The aggregate activation number tells you how busy the day was. The breakdown tells you the commission structure you should expect in settlement for that day's activations.
신규 and 번호이동 carry higher sales incentives than 기기변경 in most carrier commission structures. A day with eight activations, six of which are 기기변경, has a very different expected commission value than a day with eight activations split evenly across all three types. If your expected daily commission calculation does not account for activation type, the number will be consistently wrong and you will not know in which direction.
The activation count in the till record also serves as a daily audit checkpoint against the carrier portal. Most carriers update their activation records within 24 to 48 hours. A same-day or next-day check of the activation count showing in the carrier portal against your till record is the fastest way to catch activations that processed through the carrier but were not recorded in your POS, or vice versa.
Commission receivable versus commission received
This is the line that causes the most confusion for operators who are newer to the Korean telecom retail commission structure. Commission receivable is the estimated incentive amount you expect to receive from the carrier based on the day's activations. Commission received is the actual cash or credit that has landed in your account.
These two numbers will almost never match on a daily basis, because carrier settlement is not daily. SKT and KT settle monthly; LG Uplus settles on a 25th-of-month cutoff. So commission receivable accumulates daily, while commission received arrives in a single monthly credit. The daily till record's commission line is a running receivable, not a daily cash flow item.
Where operators misread this line is in using commission receivable as a proxy for that day's profitability. It is more accurately a contribution to the month's expected settlement position. The actual profitability of any given day depends on whether the commission rate applied in the calculation matches what the carrier will actually pay, which is not confirmed until settlement arrives.
Accessory margin
Accessory margin is the gross profit from accessories sold during the day: screen protectors, cases, charging cables, and similar items. In most Korean telecom franchise stores, accessory margin contributes 10 to 20 percent of total monthly gross profit, but it is highly variable by day and by staff selling behavior.
The accessory margin line in a daily till record is worth watching for two reasons. First, it is one of the few revenue lines where the store has meaningful control independent of carrier commission structures and activation volumes. A store that consistently attaches accessories to activations will show a materially higher monthly margin than one that does not, at the same activation volume. Second, accessory margin is the line most susceptible to till entry errors: when devices and accessories are sold as a bundle and the allocation is miskeyed, the accessory margin line absorbs the error and becomes unreliable as a performance indicator.
If your accessory margin is tracking consistently at zero or near-zero on days when you know accessories were sold, the entry workflow at the POS is the first place to check.
Cash position versus expected cash
The cash position line is the physical count of notes and coins in the till at close. Expected cash is what the POS calculates should be in the till based on cash sales and change given during the day. The variance between the two is the daily cash discrepancy.
Small variances (under 5,000 KRW) are normal and typically trace to rounding on change or minor counting differences. Persistent variances in the same direction (always short, always over) suggest a systematic entry problem. Large one-off variances usually trace to a specific transaction that was handled incorrectly: a deposit recorded as a full payment, a cash refund that was not entered in the POS, or a cash sale that bypassed the system entirely.
In Korean telecom retail, cash transactions are a smaller share of daily volume than in general retail because most device purchases go through installment financing (할부) or carrier billing arrangements. But accessory sales and device deposits often involve cash, so the cash position line is still a meaningful daily checkpoint even if total cash volume is modest.
What the daily total does not tell you
The daily till total does not tell you your actual profitability for the day, because the largest revenue component, carrier commission, will not arrive until month-end settlement. It does not tell you whether your activations will qualify for the commission rates you applied in your calculation, because eligibility depends on plan tenure and subsidy rules that may only be confirmed in the settlement file. And it does not tell you whether the activations that processed through the carrier system today will remain eligible at settlement: clawback conditions (주기 내 해지, plan downgrade within the eligibility window) can reduce the settlement amount for any activation in the month.
This is not a reason to stop tracking the daily till closely. It is a reason to treat the daily total as an operational checkpoint rather than a financial statement. The daily record catches entry errors before they age into reconciliation problems. It tracks the day's activity against the store's normal patterns. It gives you the data you need to verify the month's settlement when it arrives. Used that way, 10 minutes of daily till review is one of the highest-leverage operational habits in telecom retail.
