Every post answers one question. Not a product pitch — how the calculation you run into while selling across borders actually works.
Where automation helps, where it fails silently, and why approval before applying is cheap insurance.
Amazon Management
A launch and a mature product need different targets. How to set the strategy and when to switch.
Amazon Management
Top of search converts better and costs more. How to decide with the placement report instead of a rule of thumb.
Amazon Management
Negative keywords stop your ad showing on a query. When to add one, exact versus phrase, and why shared lists beat per-campaign entry.
Amazon Management
A bid is the maximum; CPC is what the auction charged. Placement multipliers raise the real bid above the number you typed, which is why break-even has to be computed on the adjusted figure.
Amazon Management
A keyword is what you bid on; a search term is what the customer typed. The gap between them is where broad match spends money.
Amazon Management
SQP shows the whole market on a query and your share of it, covering organic as well as paid. Which funnel step you are losing.
Amazon Management
TACoS compares ad spend to total sales including organic. What a rising TACoS with a flat ACoS tells you.
Amazon Management
There is no universal good ACoS. The right target is the product’s own break-even ACoS, which comes from its margin after fees, COGS and returns.
Amazon Management
Revenue rankings and profit rankings disagree in most accounts. The reasons are fee tiers, size, returns and ad spend.
Amazon Management
Referral fee, FBA fulfilment, storage, returns processing and other deductions — what each one is and where it appears.

Referral rates, FBA fees, shipping distance and return behaviour all differ by marketplace. How to compare them honestly.
Amazon Management
Amazon reimburses some losses automatically and leaves others to be claimed. How to compare reimbursements against inventory movements.
Amazon Management
Net profit on Amazon is sales minus referral fees, FBA fees, storage, advertising, returns and COGS. How to build the calculation per order and why monthly reports hide the problem.
Amazon Management
Matching statement lines to records, why automatic matching must be reversible, and what to do with what is left.
Pre-Accounting
A running-balance calendar beats a receivables total. Confirmed versus expected, and why marketplace payouts are not cash.
Pre-Accounting
Stock value is a cost decision, not a reporting one. What goes into unit cost and what happens when it is wrong.
Pre-Accounting
Why a marketplace belongs in the books as one account, and what stays on the order.
Pre-Accounting
Comparing expected fees against deducted fees order by order, and why the payout total always looks plausible.
Pre-Accounting
Each document at the rate of its own day, FX differences realised on payment, and why converting everything at today’s rate breaks reconciliation.
Pre-Accounting
Rare costs are the ones left out. Defining them once puts them on the calendar months ahead.
Pre-Accounting
Profit and cash answer different questions. Where the gap comes from for a marketplace seller.
Pre-Accounting
Output and input tax by rate, reverse-charge sales, and entries with no document — the three places the return and the books disagree.
Pre-Accounting
Landed cost is the real cost of a unit by the time it reaches your warehouse. How to allocate freight, duty and insurance correctly.
Pre-Accounting
Derive bundle availability from components instead of maintaining a second stock figure that will drift.
Pre-Accounting
Quantity-based matching, bundles, and what happens when an unmatched listing sells.
Pre-Accounting
Reorder timing from days of cover and lead time, with in-transit units counted and the primary route, not the fast one.
Pre-Accounting
What changes with the country and entity type: documents, tax fields and reporting — and what does not.
Pre-Accounting
Reverse charge for intra-EU B2B sales: when it applies, what the invoice must say, and how it is reported.
