The month-end spreadsheet vs event capture.
Let's be fair to the spreadsheet: it's free, everyone on the team can read it, and it bends to any rate structure a client dreams up. Most SME 3PLs bill from one, and most of those invoices go out and get paid. The problem isn't the software. It's that the spreadsheet bills from reconstruction — what someone remembers, finds or infers weeks after the work — and reconstruction is where 3–15% of billable revenue quietly leaves the building.
| The question | Month-end spreadsheet | Event capture |
|---|---|---|
| When a charge is recorded | At month-end, from memory: packing slips, WhatsApp threads, emails and a walk of the floor, reconstructed weeks after the work happened | At the moment of work: every receive, storage snapshot, pick, pack and kitting task writes its billable event against the client's rate card as it happens |
| VAS charges | The most likely to vanish — kitting, labelling and returns happen off the standard flow, so unless someone wrote it down on the 14th, by the 31st it never happened | Task = event: a VAS job carries a client and a rate from the moment it's raised, so completing the work and recording the charge are the same act |
| Storage days | Argued: “we shipped those pallets on the 12th” meets a formula in column H, and the goodwill credit usually wins | Snapshotted on schedule: GRN in-date, dispatch out-date, the days between counted by record — with long-term storage surcharges applied by rule, not by whoever remembers |
| A rate change mid-quarter | Formula archaeology: which cells got the new rate, which clients kept the old one, and which tab was copied the week before the change | Versioned rate cards per client: the new rate applies from its effective date, and every event knows which version priced it |
| Defending an invoice | Goodwill credits — the dispute costs more to fight than to write off, so it gets written off, and the client learns that disputing works | GRN-to-dispatch evidence: bin history, storage snapshots, scan records. The argument ends with a receipt, not a discount |
| Hours spent billing | Days of month-end assembly — and the Extensiv benchmark puts warehouses that can't close billing inside 16 hours a month on the wrong side of the profitability line | A review of captured events. Warehouses closing billing in under 16 hours a month are 2.8× more likely to report high profitability growth (Extensiv, 200+ warehouses) |
3–15% LEAKAGE (BEST-IN-CLASS <0.1%) AND 2.8× / <16 HRS: EXTENSIV BENCHMARK, 200+ WAREHOUSES · THE OFT-QUOTED “80%+ OF 3PLS LEAK REVENUE” IS EXTENSIV-ORIGIN — TREAT AS DIRECTIONAL
What the spreadsheet actually costs
Nothing, on the invoice from Microsoft. That’s exactly why it survives — the cost never shows up as a line item. It shows up as the charges that were never billed, because a spreadsheet can only invoice what someone successfully remembered, and month-end memory is the worst witness in the building.
- The leakage tax: the industry runs at 3–15% of billable revenue uncaptured, while best-in-class operations hold it under 0.1%. On thin 3PL margins, that band is often the entire difference between a good year and a flat one. Put your own volumes through the leakage calculator and see where you land.
- The reconstruction tax: the person building the invoice usually isn’t the person who did the work. Every charge has to travel from the floor to the spreadsheet through handwriting, memory or a WhatsApp photo of a whiteboard — and every hop drops a few.
- The dispute tax: an invoice assembled from reconstruction can’t defend itself. When a client pushes back on storage days or a kitting charge, the spreadsheet has a number but no story — so the credit note becomes the cheapest way out, every single month.
When the spreadsheet genuinely wins
Honestly: at one client and tiny volume, it does. If you run a single client’s stock, a few dozen orders a month, and the person typing the invoice is the same person who did the receiving and the picking — there’s nothing to reconstruct, because nothing was ever forgotten. The spreadsheet is free, it’s honest at that scale, and replacing it would buy you ceremony, not revenue.The line moves the day the second client arrives with a different rate card, or the day the person doing the billing stops being the person doing the work. From then on, every charge is a message that has to survive the month intact — and some won’t.
We build Binsy, the event-capture side of this table, and this page says so plainly. Our claim is narrow and checkable: keep your spreadsheet exactly as it is, let Binsy capture events alongside it for one billing cycle, and compare the two invoice drafts line by line. The difference between them is your leakage — with a number on it, from your own floor.
Keep the spreadsheet while one person can hold the whole month in their head — it works, and it costs nothing. But billing from reconstruction stops scaling the moment the floor moves faster than the memory of it: multiple clients, multiple rate cards, VAS jobs squeezed between waves. At that point the choice isn’t spreadsheet vs software — it’s whether charges get recorded when the work happens or reassembled from evidence three weeks cold. The work already happened. Bill it while it’s warm.
Run the parallel month.
Keep your spreadsheet as the control. Binsy captures every billable event alongside it for one cycle — then you compare invoice drafts and put a number on the leak.
