Formulas (excerpt, 6 of 10)

E2 — payment terms from the client list =IFERROR(VLOOKUP(B2, Clients!A:C, 3, FALSE), 30) Looks up the client's terms in the "Clients" tab; if the client isn't there, uses 30 days.

F2 — due date =IF(C2="", "", C2 + E2) Adds the terms to the issue date. Stays empty for blank rows.

H2 — status =IF(C2="", "", IF(G2<>"", "Paid", IF(TODAY()>F2, "Overdue", "Open"))) Paid if a payment date is entered; otherwise Overdue after the due date, else Open.

I2 — days overdue =IF(H2="Overdue", TODAY() - F2, "")

Dashboard!B2 — total outstanding =SUMIFS(Invoices!D:D, Invoices!H:H, "<>Paid", Invoices!C:C, "<>")

Dashboard!A5 — balance by client (one formula fills the table) =QUERY(Invoices!B:H, "select B, sum(D) where H <> 'Paid' and B is not null group by B order by sum(D) desc label sum(D) 'Owed'", 1)

Where to paste

  • Put E2, F2, H2 and I2 in row 2 of "Invoices", then drag down to row 500
  • Paste the two Dashboard formulas once; they update by themselves
  • Conditional formatting on H2:H500: text is "Overdue" → light red fill

Edge cases handled

  • Partly paid invoice: add a row with the remaining amount and a new number like INV-041b
  • Client renamed: change it only in "Clients"; the drop-down keeps rows consistent
  • Excel instead of Sheets: all formulas work except QUERY; use a PivotTable on columns B, D, H instead

Check example

Invoice INV-038, client Northside Dental, issued Sep 1, terms 14 days → due Sep 15. Today Oct 20, not paid → Overdue, 35 days.

Client: a 4-person video production studio. Tool: Google Sheets. Task: "We lose track of who has paid. We need one sheet that shows overdue invoices and how much each client owes."

The client and all details are made up.

About this service

Marketplace sellers often find that a product with a good markup barely makes money once every fee is counted. We build a per-product calculator that takes your landed cost and subtracts referral and fulfillment fees, Etsy listing, transaction and payment fees or Shopify payment fees, shipping, ad spend and returns. The fee rates sit in a settings table, so when Amazon or Etsy changes them you update one cell.

What is included

  • What you getFormulas, the calculator and settings layout as CSV text and setup steps; in Premium also a script that updates profit by SKU from a pasted order report. Delivered as text for Excel or Google Sheets.
  • Every fee countedReferral, fulfillment, listing, payment
  • Profit per unitNet margin and ROI per SKU
  • Break-even ad spendThe highest ACoS you can afford
  • Target priceThe price for the margin you want

We will ask you:

  • Do you run ads or use Etsy Offsite Ads?
  • What return or refund rate do you see?

Payment protection

You pay when you order, but the money is released only for accepted work.

  • Fixed priceThe package price does not change after you pay.
  • The money is reservedWhen you pay, the amount is only reserved. It is released to the service once you accept the work.
  • Checked before deliveryEvery result goes through a quality check before it reaches you, and you see it on the order page before accepting it.
  • Free revisionsAsk for changes within your brief as many times as the package allows.
  • Acceptance after 3 daysIf within 3 days of delivery you neither accept the work nor ask for changes, it is accepted automatically. If you write in the order chat after delivery, the order waits; once we answer, we may start the 3 days again and will say so in the chat.
  • Redo or a full refundIf the result does not match your brief and the revisions did not fix it, or the work takes more than twice its deadline, write in the order chat: we will redo the work or refund the payment in full.

Questions and answers

Are the fee rates up to date?

We use the rates you confirm from your seller account or the marketplace's fee page. They change often, which is why they sit in one settings table you can edit.

Can it read my sales reports?

Yes. You paste the order or payment report into a data sheet, and the formulas match each line to your products by SKU.

What is break-even ACoS?

It is your margin before ads as a share of the price. If ad spend per sale goes above it, that sale loses money, and the sheet shows the number for each product.
